Free travel is too small or subject to excessive load times.

Free travel is too small or subject to excessive load times. Upon request, the general clutch lever clearance between the bearing and the separation of 2.5mm more appropriate to reflect on the clutch pedal free travel for 30 ~ 40mm, free travel is too small or no free travel, will make the separation lever and separation Slewing bearing in a normally engaged state. According to the principle of fatigue damage, bearing work longer, more serious damage; load times by the more, the more easily separated bearing fatigue damage. And the longer working hours, the higher the temperature of the bearing, the easier burning, reduce separation bearing life.
(2) whether the separation was smooth adjustment lever, release fork is deformed, release bearing return spring is good, but also has a great influence on the damage to the separation of the bearing. Separate adjustment is not flat, isolated fork deformation, release bearing spring does not return, will result in the clutch release bearing against the work, so that the state is always in work release bearing, the temperature rising, burn easily release bearing, reducing the separation bearing life.

Clutch release bearing failure

Clutch release railway bearing failure
(1) Operating temperature is too high lead to overheating. Many drivers in turning or deceleration, often half-pedal clutch, some Guadang rear foot on the clutch pedal also; Some vehicles free travel adjustment is too large, making the clutch is not complete, in a semi-bonding, semi-isolated state, this causing the state of the friction generated between the sliding friction plate and flywheel, a large amount of heat transmitted to the bearings, the bearing is heated to a certain temperature, the melted grease or diluted flow, the temperature of the bearing to further improve the separation, when the temperature reaches a certain degree will burn bad release bearing.
(2) the lack of grease and abrasion. Clutch release bearings with grease lubrication. Repair personnel in practical work release bearing lubrication problem is easy to ignore, and do not release bearing lubrication during installation, causing the clutch release bearing starvation. No lubrication or less the amount of wear of bearings lubricated separate release bearing lubrication is often several times to several times. Wear increases, the temperature will increase greatly, so more damage to the release bearing. So in the repair process, the installation of the clutch release bearing lubrication to check, timely lubrication maintenance.

XR series of cross-tapered roller bearings designed to provide high accuracy and rigidity of rotation in a smaller space

XR series of cross-tapered roller automotive bearing designed to provide high accuracy and rigidity of rotation in a smaller space, dramatically saving material costs. These bearings are the two bearing raceways and rollers are mounted together cross at right angles, adjacent roller in the opposite direction, is mounted between the roller and roller isolation block, the roller is also equipped with support pads this allows the rollers to fit into the two half-columns in the same space. Angle and taper bearing geometry makes bearings effective span than the actual width of the bearing itself several times.
XR series bearings for high-speed machine tool applications such as vertical boring and vertical grinders. Many are also particularly suitable for the limited space, high precision rotating equipment.

Crossed roller bearings internal structure was 90 ° roller arranged perpendicular cross

Crossed roller Wind turbine bearing internal structure was 90 ° roller arranged perpendicular cross,
Spacing between rollers fitted retainer or isolation block to prevent roll-tilt roller mill mutual observation between child, effectively preventing the increase in rotational torque. Further, one of the rollers does not occur or the latch-up phenomenon of the contact; same time as the inner and outer ring is a split structure, the gap can be adjusted even if the preload is applied, can be obtained with high accuracy rotation.
2, the operation simplifies installation
Divided into two parts of the outer or inner ring, and after loading the roller holder is fixed together, so when you install operation is very simple.
3, bear large axial and radial loads
Because the rollers are arranged vertically spaced retainer by 90 ° to each other in a V-shaped groove raceway, this design makes cross roller bearings can withstand higher radial load, axial load and moment load and all load direction.
4, substantial savings in installation space
Small, thin structure of particular cross-roller bearing inner and outer rings is a minimum size is close to the limit of small size, and has high rigidity, so the most suitable for the joints of an industrial robot or a rotary portion of the rotary machining center versatile table, robot rotating part, precision rotary tables, medical equipment, measuring instruments, IC manufacturing devices.
High 5 speed capability
Reducing the length of the shaft 6 and the processing cost, result in a limited thermal expansion changes the geometry

Cross roller bearings

Cross roller super-precision bearing, because the inner or outer ring is split, and the interval after loading the roller cage, and Cross-Roller Ring secured together to prevent separation from each other, so when you install the Cross-Roller Ring Operation simple. Since the roller is staggered, so only one set of Cross-Roller Ring can withstand the loads in all directions, compared with the traditional model, rigidity increased by 3 to 4 times. Meanwhile, due to cross roller bearing inner or outer ring is constructed of two split, adjustable bearing clearance, even if they are applied preload can be obtained with high precision rotary motion.

Crossed roller bearings are roller between the inner and outer wheel....

Crossed roller surface profile measurement are roller between the inner and outer wheel intervals intersecting at right angles to each other arranged. They can withstand the load from all directions (such as an axial thrust or momentum load, etc.). Due to the roller surface into line contact with the rail, therefore, the possibility of bearing a load and elastic deformation is small. This type of bearings are widely used in industrial automation, such as robots, machine tools and medical facilities, etc., need high rigidity, compact and high-speed still ensuring accurate of occasions.
In cross roller bearings, cylindrical roller in was due to a 90 ° V-shaped groove raceway is vertically aligned with each other through a spacer retainer, so a cross roller bearings can bear radial load, axial load and load torque loads in all directions and so on. Minimum size of the inner and outer rings are miniaturized, in particular close to the limit of a very thin type of compact size, and has high rigidity, it is most suitable for the joint portion or a rotating portion of the industrial robot, the rotary table of the machining center, use the rotating portion of the manipulator, precision rotary tables, medical equipment, meters, IC manufacturing equipment, etc..
