In addition to SKF Nautilus bearing cage design,

In the early market, in order to meet the design requirements for single bearing, usually bearing the three cylindrical roller bearings. The design is similar slewing bearing, a rolling body (similar to the cylindrical roller bearings) to bear all of the radial force, the other two rolling elements (similar to roller thrust Precision bearing) bear a bidirectional axial force. The bearing of the bearing arrangement appears to meet some of the features alone, but by running the analysis bearing thrust bearing function as two rows of rolling bodies to make the whole circle of the bearing is rotated, the both end surfaces of the rolling elements can not achieve the same speed, which it means that the bearings during the large number of sliding friction. And as rolling bearings, sliding friction is to try to avoid, because it will not only bring more bearing heating, while the lubrication of sliding friction in the bearing lubrication is also a very difficult question. Because of the design on some of the issues, the bearing is now unable to meet the growing power of the wind turbines to the demand.
Comparison of different designs cage
In addition to SKF Nautilus bearing cage design, the market there are several different cage designs. Respectively, are to compare the advantages and disadvantages of several cage.
Figure 4 is one of the wear metal pin-type cage. As the name implies, the rolling elements of the bearing design of the through hole in the middle of a rolling pin are connected to the ends of the retainer ring side. By design, the size of this bearing rolling elements bearings other than the same size is much larger, because not only sufficient to meet the load carrying capacity, but also in the rolling open a hole inside the body in order to wear a pin-type cage installation. In addition, the lubrication of the sliding member is an important issue, which has been mentioned in the above. The body bore bearing rolling pin and cage wear are all between the sliding friction, lubrication problems not only not been resolved, it brings the bearing heating and must be of concern.

The Nautilus bearing contact angle break through the traditional design,

The traditional pairing (or double row) tapered roller bearings, the contact angle is generally only 20 or so, to ensure its larger radial load capability, Bearing test machine axial load carrying capacity and the ability to withstand the overturning moment has certain limitations. Therefore, to ensure that a spindle designed to meet the application requirements, there must be another as a second pivot bearing to bear additional radial force, and the two bearing configurations, to meet the axis when subjected to the overturning moment , no deformation.
The Nautilus bearing contact angle break through the traditional design, the contact angle of each single bearing enlarged to 45. With conventional dual bearing configuration comparison, Nautilus bearing two single bearing contact points of connection is much higher than the normal distance between the tapered roller bearing, which connect two points of contact can be used as the point of intersection of two entire shaft a focus, a support shaft running spots.
segmented plastic cage
In addition to the larger contact angle, but the bearing Another notable feature is the use of segmented plastic cage. Internal parts of the bearing, the rolling bearing is an important component, in addition to maintaining the roll cage operating state, there are separate to avoid their mutual rolling friction function. Cage is not a force element, can not afford any form of force. Accordingly, it is often used to produce lighter material, while maintaining the frame material to meet another requirement that sufficient strength. Since the operation of the bearing cage rotation power needed is provided by the rolling body, therefore, the holder of the material requires a certain strength to ensure its normal operation.
For SKF Nautilus bearing, in order to ensure that the contact angle connection enough to withstand the force system, bearing sizes are often very large, more applications currently on the market with a diameter of 2 ~ 2.5 m of bearing products. Therefore, reducing the weight bearing itself as its design need to overcome technical problems. As part of the inner and outer bearing rings and rolling elements, in order to ensure that the bearing capacity, in the selection can not have the slightest careless. SKF Nautilus bearings of plastic, not only to ensure adequate strength and weight, to ensure the rotation of the bearing performance, while reducing friction within the bearing.
Segmented design SKF Nautilus bearing another feature (Figure 3). Four or five in the bearing rolling elements sharing a cage assemblies, and each cage without any other links between the components. If the bearing used in the conventional one-piece cage, the size is too large, the weight of the holder causes it to deform in the bearing during operation, this deformation causes the rolling element and the additional contact with the cage, generate additional friction. This will not only increase the bearing operating temperature, but also on the cage and rolling friction material wear and tear can lead to even rolling element cage deformation, and ultimately affect the carrying capacity of the bearing or even life.
Segmented cage, each individual component is very small, even if many components together, will not produce distortion. Also, because each component is only four to five rolling, therefore, the friction generated by the holder will be reduced to a minimum.
3 Application Features
Nautilus bearing is now widely used in high-power wind turbine, instead of the dual bearing design, reducing the size of the drive chain. So what this application can bring benefits in the end, in the application will produce what the problem?
Spindle conventional wind turbine designs, the division of the bearing force is generally fixed side bearings to withstand the axial load and part of all radial load, and the other end of the receiving section as a floating bearing radial load. Wind farm Wind determines the required size of the load bearing size, the bearing size is determined the distance between the two bearings, and also determines the length of the transmission chain.
Single bearing (Nautilus) is designed to ensure the same conditions, the bearing force by a bearing to withstand all of the axial and radial loads, reducing the size of the entire transmission chain. Single bearing design should be considered in addition to the internal preload, but in terms of the application of the bearing with double bearing without any distinction. And single bearing special cage design, so that in grease and oil lubrication conditions have a very good performance.
Only a bearing on the spindle, have realized the role of two bearings, then the stiffness of the bearing in the bearing design has become a key factor that must be considered. Nautilus bearing inner ring for the two separate parts, the application by checking wind turbines, in the production of bearing internal clearance will be designed into the ideal range, the bearing after installation, you can achieve optimal pre-
Clamping force, simplifying installation of bearings

At the same time according to the working conditions of the bearing

Blade spindle bearings (24044CC)
Blade spindle by two spherical roller bearing. As Blade spindle bear the load is very large, and very long shaft, easily deformed, therefore, requires the bearing must have good self-aligning performance.
Determining internal bearing and cage structure parameters of the structure, the bearing has good performance and long life.

Gearbox mountings
Gearbox bearings in many types, mainly by gearbox gear oil lubrication. More metal particles in lubricating the bearing life is greatly shortened, therefore required to adopt a special heat treatment process, so there raceway surface compressive stress, reduce particulate impurities raceway on the degree of sensitivity, improved bearing life. At the same time according to the working conditions of the bearing, the bearing structure further optimized design, improved bearing processing method, and further improve bearing performance.

Generator bearings
Generator wheel bearing and cylindrical roller bearings deep groove ball bearings. By these two bearing structure design, processing methods to improve the production process controls and related components cleanliness preferable to lower the vibration noise of the bearing, the bearing

In order to ensure safe and reliable operation of the pitch bearing

Wind turbine pitch wind turbine bearing grease selection
In order to ensure safe and reliable operation of the pitch bearing, the work in pitch bearing to minimize friction and wear, avoiding the pitch bearing and the inner surface of the ball channel failure, the bearings must be lubricated. Bearing lubrication and cooling, dust, rust, sealing, cushioning and so on.
Bearing lubrication can be divided into two kinds of grease and oil lubrication. To prolong the life of the pitch bearing, the bearing must be based on the conditions of use, the adoption of appropriate lubrication. Grease has good adhesion is not lost, does not drip, compression resistance, sealing against dust resistance, good corrosion resistance and other characteristics. In the low, medium, medium temperature, high load bearing operation using very common. As the pitch bearing condition is a high load, low speed, the pitch of the bearing means are lubricated with grease. Grease is a base oil, thickener and additives between the between the solids and semi-fluid lubricant. In the content of the grease base oil accounts for 80-95%, and only when under pressure grease base oil from the grease to lubricate the flow effect, when the pressure is removed, grease base oil can be re-absorbed, grease lubrication performance is determined by the performance of the base oil. Grease consistency (from soft to hard) inside grease thickener is determined by the number, the liquid may contain only 2% of grease thickener, and the thick grease may contain from about 20% of the thickening agent. The content and type of additives to form a variety of different characteristics of grease, bearing grease are commonly used calcium based grease, sodium grease, sodium calcium based grease, lithium grease, aluminum grease disulfide molybdenum grease and so on.
A pitch bearing according to the actual conditions, the selection of the pitch bearing grease are taken into consideration fat types of additives, the viscosity of oil, grease dropping point,; E13N oil pumping performance and other properties of the needle penetration.

Check the toothed belt

(1) Check the toothed belt wheel bearing position shown in Figure 3.
    Toothed belt is used in the transmission between the crankshaft and camshaft work, which not only guarantees the accuracy of the transmission, and noise. But after a long toothed belt usage occurs after hardening, cracking, peeling off, loose fibers and other wear and damage to the phenomenon, and in severe break. If it is found during an inspection of the above, you must replace the toothed belt.

Check the belt installation state.

   Some engines using a flat fan belt pulley mounted on the belt and the pulley should be checked with the situation shown in Figure 2. Flat-belt pulleys should fit well, or belt life will not last long. Is used on some bearing manufacturer V-belt. V-belts should be installed to achieve the state shown in Figure 2, the error phenomenon, should be promptly corrected.

Adjust the V-belt tightness.

  If the fan belt is too loose, it will cause insufficient charging and engine overheating failure.
     The fan bearing manufacturer  the adjusting bolt of the entire alternator displaced in or out to adjust the tightness of the belt shown in Figure 1. Adjustment, shall be securely tightened bolts. Be careful not to adjust the belt too tight, otherwise the belt tight through the General Assembly hurt fan belt and bearings. Operation should be taken to avoid contamination belt is grease, otherwise it will cause slipping and shorten its life.

Check belt condition and tightness.

   Check belt for damage, spalling, bearing manufacturer before the break, there will be slipping sound of the belt surface will be cracked cracks, wear and spalling and other precursory phenomena. Therefore, should be carefully observed, such as the above phenomenon should be replaced belt (note the difference: the belt tightness is not enough, there will be slipping sound). Check the fan belt tightness, with the thumb to 9-10kg of force when pressing the middle of the belt, the deflection should be 5-1Omm. If you do not meet the requirements, should be adjusted.

Check the V-belt condition, adjust the tension

 Check and adjust the belt tightness
     Insufficiently charged, the temperature rises too fast basic reasons too loose fan belt or belt failure. wheel bearing the fuel in the cylinder, a considerable part of the work done with the cooling consumption among various losses. Because of the high temperature combustion engine parts will be welded shut, so the majority of car engine with water cooling the engine to maintain a certain temperature.
     Supplement battery power, air conditioning systems, and many other accessories are needed driven by the belt to work. Therefore, V-belt on the engine is critical, belts bad state, the engine is not working. ,

Install thrust ball bearings should note the following:

A) distinguish between the taper roller bearing  ring and tighten loose ring (according to bearing bore size judgment, aperture difference O.1 ~ O.5mm).
2) **** Koo distinguish mechanism (that is, without moving parts, mainly refers to the assembly).
3) No matter what happens, the bearing ring should always be loose against the end face of the stationary member

Bearing installation method, under normal circumstances the majority of the shaft

ft rotates, so the inner ring and shaft with an exaggeration win cooperation,

Bearing outer ring and bearing manufacturer chamber fit for the clearance fit. Thrust bearing assembly primarily axial load, and its application

Extensive. Although the thrust bearing installation operation is relatively simple, but the actual repair is still often errors occur, namely the bearing ring and loosen tight

Ring mounting location is incorrect, the results of the bearing out of action, the journal will soon be worn. Tight inner ring and the journal for the transition fit

When the shaft rotates driven tight ring, and with the stationary element face friction, subjected to axial force (Fx), the friction will occur

Torque is greater than the inside diameter with resistance torque, resulting in tight ring and the shaft with face mandatory rotation, exacerbated journal wear.

thrust ball bearing installation precautions and the use of performance

 Thrust ball Bearing manufacturer can withstand high speed thrust load design, the ball rolling with a rolling groove of the washer-like ring structure

Percent. Because saddle-shaped rings, therefore, thrust ball bearings are divided into flat seat type and tone spherical thrust ball bearings hheey

Seat model types. In addition, the bearings can withstand axial load, but can not bear radial load. Comprehensive and bearing force

Shaft with generally transition fit, seat ring and the bearing housing bore with the generally loose fit, so this bearing easier installation

, Spring thrust bearing should the shaft axis fixed relative to the axis of rotation in order to prevent

Tapered Roller Bearings

taper roller bearing inner ring and the outer ring raceway is conical roller, it is also rolling cone, the apex of the conical surface are three polylactide point on the bearing axis. This design makes tapered roller bearings particularly suitable for both radial and axial directions of combined loads. Bearing axial load size, depending on the size of the contact angle α. Commonly used in the bearing dimensions table angular size of the calculation of the coefficient A represents a, a larger value withstand greater axial load. Tapered roller bearing load carrying capacity of the same size is much larger than the angular contact ball bearings, but it's far below the speed limit angular contact ball bearings, so it is commonly used in low speed, heavy load bearing lathes, boring and milling machine and jig boring on the spindle.

Tapered roller bearings series consists of a separable outer ring and the inner ring, cage, roller assembly combination. For precision tapered roller bearings, the outer ring are not interchangeable.

Clutch control mechanism divided into mechanical steering mechanism

 Hydraulic control mechanism, in order to reduce taper roller bearing lutch pedal force, and not because of the transmission gear ratio is too large to increase the pedal stroke, in some heavy-duty trucks and some cars with a clutch pedal power devices. There is also a pressure-assisted clutch control mechanism using the engine driven air compressor operation as the main energy sources, the driver's body as a secondary or backup the manipulation of energy, more with the car's air brake system or other pneumatic devices share a compressed air source.

Clutch adjustment

Clutch use, the driven plate thinning due to wear and tear, the free gap becomes smaller, ultimately affect the normal clutch engagement, so the use of the clutch needs to be adjusted over time. Clutch adjustment is intended to ensure proper free play. Clutch adjustment method according to the location and specific models may be. Clutch pressure plate is active member, always with the flywheel, usually by projection, a key or pin drive, it rotates together with the flywheel, and the pressure plate and can be moved backward relative to the flywheel, the clutch. Driven mainly by the driven plate body plate, friction plate and driven disc hub consisting
From the separator to the engagement of the clutch bearing in the process, friction between the flywheel and the pressure plate to friction, generate a lot of heat. These calories need to be shed in order to avoid friction disc damage due to high temperatures, so the clutch cover has a window, and some also made ​​a wind guide sheet, in order to strengthen its internal ventilation

Clutch pedal free travel

To eliminate from the clutch pedal free play is the corresponding free travel pedal stroke. Clutch pedal clutch pedal working stroke working stroke :
eliminate free play, continue to depress the clutch pedal, there will be slewing ring  this process corresponding to the pedal stroke is working stroke. Clutch working process can be divided into the separation process and the engagement process in the separation process, the clutch pedal, the clutch free travel within the first elimination of the free space, and then in the working stroke to generate separation gap clutch
In the bonding process, gradually release the clutch pedal, pressure plate under the action of the compression spring to move forward, first remove the separation gap, and in the pressure plate, driven plate and the flywheel effect work surface sufficient clamping force; after release bearings under the action of the return spring moves backward, resulting in free play, the clutch engagement.

Clutch Works

Automotive driveline clutch is directly linked with the engine parts, which is responsible for the transmission of power and cutting and binding effect, so we can ensure a smooth start when the car slewing ring, but also to ensure the smooth shifting, but also to prevent the transmission overload. Today we'll look at a simple understanding of the working principle of the clutch, as well as several common clutch.
The clutch is a drive mechanism, which has active part and a driven part, the two parts being separated may also be combined slowly, and in the transmission process, there may be relative rotation, so that the clutch between the drive member and the driven member will depend on contact friction to transfer torque, or the use of the pressing force required by the friction, or the use of liquid as the transmission medium, or the use of magnetic transmission, etc. to transmit torque.
Now widely used in the car is by spring-loaded friction clutch. The car is moving in the process need to keep the power transmission, power is only a temporary interruption needs, so in the process of moving a long period of the driving and driven parts bound state, when the driver depresses the clutch pedal, through mechanical transmission, let the driven part and active part of the separation
  Friction clutch, the friction surface used as the number of forms and the compression spring mounting position and the operating mechanism with different, there are many different. Divided by the number of driven disc and double-disc clutch single plate clutch. One single plate clutch is mainly used in cars and light trucks, while the double-disc clutch torque transmitted is large, so is mainly used for medium and heavy vehicles. In accordance with the compression of the spring structure is divided into a coil spring clutch and the diaphragm spring clutch.

Wind turbine bearings

  Yaw bearing assembly (660PME047)
Turbine yaw bearing assembly is guaranteed timely tracking changes in wind direction. Fan slewing ring, yaw acceleration ε will have an impact torque M = Iε (I inertia of the cabin). Yaw speed Ω higher, the greater the acceleration ε. Because I very large, so that the already great impact multiplied. In addition, the fan if the process in motion deflected yaw gear will withstand considerable gyroscopic moment, likely to cause fatigue failure of the yaw bearing.
According to the mechanical characteristics of the fan bearings, yaw bearing a "zero clearance" Designing a four-point contact ball bearings, the channel for special design and processing, can withstand large axial load and moment loads. Yaw gear to choose the right materials, modulus, hardness of tooth surface contours and to guarantee the life and the matching between the driving gear. Meanwhile, we must adopt appropriate treatment measures to improve the strength of the tooth surface, the bearing has good abrasion resistance and impact resistance.
Fans exposed to the wild, so the sealing performance of the bearing has strict requirements that must form the bearing seals to optimize the design of the bearing sealing performance simulation study, the bearing life and the life of the same fan. Fan mounted on the altitude of 40m, expensive assembly and disassembly, so there must be a very high level of reliability, generally require 20 years of life, coupled with the bearing structure is complex and therefore must be installed prior to the test computer simulation tests to ensure that the bearing design parameters correctly.

Wind turbine pitch bearing grease selection

In order to ensure safe and reliable operation of the pitch bearing, the work in pitch bearing to minimize friction and wear, avoiding the pitch bearing and the inner surface of the ball channel failure, the bearings must be lubricated. Bearing lubrication and cooling, dust, rust, sealing, cushioning and so on.
Bearing lubrication can be divided into two kinds of grease and oil lubrication. To prolong the life of the pitch bearing, the bearing must be based on the conditions of use, the adoption of appropriate lubrication. Grease has good angular contact ball bearing is not lost, does not drip, compression resistance, sealing against dust resistance, good corrosion resistance and other characteristics. In the low, medium, medium temperature, high load bearing operation using very common. As the pitch bearing condition is a high load, low speed, the pitch of the bearing means are lubricated with grease. Grease is a base oil, thickener and additives between the between the solids and semi-fluid lubricant. In the content of the grease base oil accounts for 80-95%, and only when under pressure grease base oil from the grease to lubricate the flow effect, when the pressure is removed, grease base oil can be re-absorbed, grease lubrication performance is determined by the performance of the base oil. Grease consistency (from soft to hard) inside grease thickener is determined by the number, the liquid may contain only 2% of grease thickener, and the thick grease may contain from about 20% of the thickening agent. The content and type of additives to form a variety of different characteristics of grease, bearing grease are commonly used calcium based grease, sodium grease, sodium calcium based grease, lithium grease, aluminum grease disulfide molybdenum grease and so on.
A pitch bearing according to the actual conditions, the selection of the pitch bearing grease are taken into consideration fat types of additives, the viscosity of oil, grease dropping point,; E13N oil pumping performance and other properties of the needle penetration.
