ZYS clutch bearing damage causes

ZYS clutch bearing operation and maintenance of bearing damage and the driver to adjust a great relationship, damage generally have the following reasons:
1) Operating temperature is too high overheating
Many drivers cornering or deceleration, often half-pedal ZYS clutch bearing, some hanging files also on the back foot Bearing test machine pedal; some vehicles free stroke adjustment is too large, making the ZYS clutch bearing is not complete, in a semi-engaged semi-isolated state, this state Dry friction caused by a large amount of heat transfer to the bearings, bearing the heat reaches a certain temperature, melt butter or diluted flow, so that the release bearing temperature is further increased when the temperature reaches a certain level will be burned.
2) lack of lubrication and wear
Bearing life testing machine release bearing grease lubrication, there are two methods added butter, for 360,111 bearings, it should be removed or transmission, open the back cover of the bearing grease fill during maintenance, and then re-install the cover close to; for 788611K bearings, it may remove it in the melted grease digesting, removed after cooling, can achieve the purpose of lubrication. In practice this is easy to overlook the driver, causing the ZYS clutch bearing release bearing short of oil. Separation of wear of the bearing lubrication or less in the absence of lubrication is often lubricated amount of wear several times to several times. Wear increases, the temperature will be greatly improved, so more damage.
3) free travel is too small or too many times by the load
Upon request, the general ZYS clutch bearing release bearing and the separation gap between the lever is 2.5mm more appropriate to reflect on the ZYS clutch bearing pedal free travel is 30-40mm, free travel is too small or no freedom of travel, and will make the separation lever release bearing is normally engaged state. According to the principle of fatigue damage, bearing work longer, the damage more serious; the more times by the carrier, the more easily separated bearing fatigue damage. And the longer working hours, the higher the temperature of the bearing, the easier burning, reducing the separation of bearing life.
4) In addition to the above three reasons, the separation lever is adjusted to smooth out bearing return sp

ZYS clutch bearing Caution

1) In accordance with operational requirements, to avoid half-engaged ZYS clutch bearing semi-isolated state, reduce the frequency of use of the bearing measurement
2) pay attention to maintenance, or when a regular annual maintenance in vetting, by cooking method make butter soaked it with ample lubricant.
3) Note leveling ZYS clutch bearing lever return spring force to ensure compliance.
4) Adjust the free travel, it meets the requirements (30-40mm), to prevent the free travel is too large or too small.
5) Minimize engagement separation times, reduce the impact load.
6) Cross roller bearings light step, easy to engage smoothly and separation.

ZYS clutch bearing action


ZYS clutch bearing  installed between the ZYS clutch bearing and the gearbox, separate loose sleevesealed angular contact ball bearings on the transmission of the first axis of the tubular extension of the bearing caps, by the return spring to release bearing shoulder always against the release fork, and retreat to the final position maintain the separation lever ends (separation means) about 3 ~ 4mm gap.
The ZYS clutch bearing pressure plate, release lever and the engine crankshaft synchronous operation, and the separation ZYS clutch bearing fork can move axially along the output shaft, with the release fork to direct dial release lever is clearly not enough, by separating the bearing can release lever while rotating an edge ZYS clutch bearing output shaft axial movement, thus ensuring the smooth Super precision ball bearings to engage, separation soft, reduce wear and extend ZYS clutch bearing life and the entire drivetrain.

ZYS clutch bearing Failure

(1) Free travel by excessive load is too small or the number. According to the requirements, generally ZYS clutch bearing gap between the Bearing manufacturing machine and the separation lever is 2.5mm more appropriate, is reflected in the free travel of the ZYS clutch bearing pedal 30 ~ 40mm, free travel is too small or no free travel, will make the separation with the separation lever Bearing in a normally engaged state. According to the principle of fatigue damage, bearing work longer, the more severe the damage; the more times by the carrier, the more easily separated bearing fatigue damage. And the longer working hours, the higher the temperature of the bearing, the easier burning, reduce the service life of bearings.

(2) whether the separation was smooth adjustment lever and release fork is deformed, release bearing measurement return spring is good, but also have a significant impact on the release bearing damage. Separated uneven, release fork deformation, release bearing spring does not return, will result in the ZYS clutch bearing release bearing against the work, the separated bearing condition is always in work, higher and higher temperatures, burn easily bearings, lower bearings life.

ZYS clutch bearing Failure

(1) excessive operating temperatures result in overheating. Many drivers cornering or deceleration, often half-pedal ZYS clutch bearing, and some also on the back foot in gear ZYS clutch bearing pedal; some vehicles free stroke adjustment is too large, making the ZYS clutch bearing is not complete, in a semi-engaged, semi-isolated state, this Status cause friction generated between sliding friction plate and flywheel, a large amount of heat transfer to the Wind turbine bearing, bearing the heat reaches a certain temperature, melting grease or diluted flow, so that the release bearing temperature is further increased when the temperature reaches a certain level will burn bad bearings.

(2) the lack of grease and abrasion. super precision bearings  lubricated with grease. In practice repairman Neglected release bearing lubrication problems, not the release bearing lubrication during installation, leading to ZYS clutch bearing release bearing short of oil. No lubrication or less the amount of wear lubricating bearings are often lubricated bearings several times to several times. Wear increases, the temperature will increase a lot, so more damage bearings. So in the repair process, the installation of the ZYS clutch bearing release bearing lubrication to be checked, timely lubrication maintenance.

ZYS clutch bearing Works

Automobile Dental bearing release bearings are a more important part, if not faulty maintenance, will not only cause economic loss, but also dismantling a rather cumbersome, need to spend a lot of man-hours. So, find out the ZYS clutch bearing release bearing cage failure cause and reasonable care and maintenance in use, to extend the life of bearings, improve labor productivity, achieve better economic efficiency are important. When the ZYS clutch bearing release bearing work, the ZYS clutch bearing pedal force will be transmitted to the ZYS clutch bearing release bearings.  ZYS clutch bearing pressure plate toward the center, so that the pressure plate is pushed away from the ZYS clutch bearing, the ZYS clutch bearing plate and flywheel separation. When the ZYS clutch bearing pedal is released, the pressure plate before the spring pressure will push the pressure within the disc, press the ZYS clutch bearing, the ZYS clutch bearing plate and ZYS clutch bearing  separation, and complete a cycle.
