Question description

1. The working conditions of the clutch release bearing and forceRelease bearing in the process of using the axial load, impact load, and the effect of high-speed rotation of the radial centrifugal force, in addition, because the fork lift and separation of leverage reaction is not a straight line, also form a torque. Clutch release bearing poor working conditions, the intermittent high-speed rotation and high friction, high temperature, lubrication condition is bad, no cooling conditions.2. The failure reasons of clutch release Low Price SKF 608 BearingClutch release bearing damage and the driver’s operation and maintenance, the adjustment has much to do, the damage reason to roughly the following:1) working temperatures cause overheatingMany drivers in turn or slow, often a half step clutch, some shift hind feet still on the clutch pedal. Some vehicles free stroke adjustment is too large, to separate the clutch is not completely, in joint and separation condition, the dry friction caused by the state of this and produce a large amount of heat transfer to the release bearing, bearing is heated to a certain temperature, melt the butter or dilute flow, make the separation bearing temperature rise further, when the temperature reaches a certain extent it burn out.2) lack of lubricating oil and wearClutch release bearing lubrication in butter, butter to join, there are two ways for 360111 release bearing, should be in the maintenance or remove the transmission, fill open rear cover of the bearing grease, then the back cover to fit up; For 788611 k release bearing, it can tear it down in the molten grease dip cooked, take out after cooling, can achieve the purpose of lubrication. Driver is easy in the practical work, which is blind to this point, cause the clutch release bearing short of oil. In separation without lubrication or less lubrication bearing lubrication and is often worn after several times to dozens times the amount of wear and tear. Wear increases, the temperature will also have greatly improved, and thus are more likely to be damaged.3) free stroke is too small or too many loadedAccording to requirements, the clearance between the separation between the lever and the clutch release bearing is more suitable for 2.5 mm, reflect on the clutch pedal free stroke for 30 to 40 mm, free stroke is too small or no free stroke, will make separate lever and is often joint state of release bearing. According to the principle of fatigue damage, the bearing working time long, the more serious damage. Under load, the more isolated bearing is easy to produce fatigue damage. And the longer you work, bearing the higher the temperature is, the easier it is burning, reduces the service life of the release bearing.4) in addition to the above three reasons, split the lever to adjust whether level off, the release bearing return spring is good, has a great influence on the release bearing damage also.
