Dust into the wind turbine bearing,increasing noise

In recent years, the major bearing manufacturers in terms of the radiator's new technology, Wind turbine bearing , such as magnetic bearings, water bearing, bearing core, to Fu bearings are also on top of the basic forms of bearings made to improve the operation of the principle did not change .

Ordinary air-cooled radiator oil bearings and ball bearings are mainly used.And this bearings over time, due to the oil seal (computer radiator products are impossible to use high-grade seals, generally is ordinary paper seals), insert ball bearing ,oil will gradually evaporate and dust will enter the bearing, causing the fan slow speed, noise increases and other issues, but also because of a serious bearing wear caused by severe vibration caused by eccentric fan. These phenomena, Deep groove ball bearing either open seal refueling, or to purchase another new fan only eliminated.

ZYS wind turbine bearing

Bearing type is the air-cooled heat sink fan-shaped bearing type used. In mechanical engineering,Wind turbine bearing ,bearing class shaped very much, but also on the radiator so few products in use, the use of sliding friction sleeve bearings and use a rolling bearing friction ball bearings and two forms of combining these three.


The use of oil-bearing sliding friction sleeve bearings, when used as a lubricant and lubricant DRA initially run using low noise,angular contact thrust ball bearing , low manufacturing costs, but this badly worn bearings, ball bearing life than there is a big gap.

Deep groove ball automotive bearing are the most commonly used rolling bearings. It's simple and easy to use. Mainly used to bear radial load, but increase the bearing radial clearance, with certain features of the angular contact ball bearings can withstand radial and axial joint load. When should not be used in high speed and thrust ball bearings, can also be used to bear the pure axial load. Deep groove ball bearings with the same sizes of other types of bearings, such bearings friction coefficient, high speed limit. But the impact of intolerance, unfit to bear heavy loads.
In many cases, bearing corrosion will occur, leading to corrosion of bearings There are many reasons, the most common in our daily lives mainly in the following several factors.
1) due to poor sealing means is penetrated moisture, dirt, etc.;
2) bearing long-term need, more than rust period, the lack of maintenance.
3) the metal surface roughness is relatively large;
4) contact with a corrosive chemical media, bearing cleaning is not clean surface dirt buildup, or sweat hand contact bearings, the Hydrodynamic Bearing cleaning, packing or installation is not timely, long-term exposure to the air, water and air by the invasion contamination;
5) the ambient temperature and humidity and exposure to various environmental media; rust inhibitor failure or quality does not match the requirements.

Paired angular contact ball bearings can bear radial

Paired angular contact ball bearings can Hydrodynamic Bearing radial load mainly radial and axial joint load can also be subject to pure radial loads. Tandem configuration can only bear axial load in one direction, the other two configurations can withstand axial load in either direction. This type of bearing is generally matching pairs by the manufacturer to submit a user after installation preload interference, rings and balls in the axial pre-load condition, thereby enhancing the entire group as a single bearing support stiffness and rotation accuracy.

Angular contact ball bearings

Angular contact ball bearings: 7000C-type (α = 15 °), 7000AC type (α = 25 °) and 7000B (α = 40 °) of several types. This kind of bearing lock port on the outer ring, the inner and outer rings can not be separated in general, can withstand radial and axial joint load and axial load in one direction. Axial load capacity from the contact angle, the contact angle is larger, the ability to withstand high axial loads. This kind of Rolling mill bearing can limit the axial displacement in one direction shaft or housing.
Higher speed limit contact ball bearings can support radial load and axial load can also be subject to pure axial load, axial load capacity by the contact angle and the contact angle increases with the increase.

Universally matchable bearings are specially processed

Universally matchable bearings are specially processed, when the vibration measurement is installed close to each other, any combination can achieve the established internal clearance or preload, and the average load distribution, without the use of shims or similar devices.
Paired bearing applications: When insufficient load carrying capacity of a single bearing (using channeling associated configuration) or when to bear the role of joint load or axial load in both directions (with back to back or face to face configuration).
2, the basic design of the bearing (can not be used as general-purpose with the group), is used to configure the way the individual bearings
Single row angular contact ball high precision bearing are mainly applied basic design of only one bearing configuration at each location. Its width and the amount of outstanding ordinary level tolerances. Therefore not suitable for the two single row angular contact ball bearings close to the installation.

If paired installation

If paired installation, so that one pair of bearing outer ring relative to that wide side face of wide and narrow side facing the narrow end. This can avoid additional axial force, and the shaft or housing to limit axial clearance within the range in both directions.
Its inner and outer ring raceway relative displacement on the horizontal axis, so it can support radial load and axial load - combined load (single row angular contact ball surface profile measurement can withstand axial load in one direction, so often paired installation).
Cage made ​​of brass, synthetic resins, etc., depending on the bearing forms, and application conditions.
More angular contact ball bearings are manufactured abroad bearing manufacturers, domestic applied to imported equipment such as more angular contact ball bearings 3204RS, etc.
Think back to back, back to front contact contact more simple, narrow side out, including wide-brimmed, another broadside included, narrow home, is back to back contact.
