Clutch disengaging bearing

1. Clutch separation bearing function

The clutch separation bearing is installed between the clutch and the transmission, the separation bearing seat is loosely sheeted on the tubular extension of the first shaft bearing cover of the transmission, and the shoulder of the separation bearing is always against the separation fork through the return spring, and the final position is maintained with the separation lever end (separation refers to) about 3~4mm clearance.

Due to the clutch pressure plate, separate leverage and engine crank synchronous operation, and the separation of the fork can only move, the clutch output shaft axis with separation fork to dial directly separate lever is obviously not enough, by rotating a separation bearings can make separation lever side edge of the clutch output shaft axial movement, so as to ensure the clutch can engage a smooth, separation of downy, reduce wear and tear,Prolong the service life of the clutch and the whole transmission system.

2. Clutch separation bearing condition

In the process of use by the axial load, impact load and high-speed rotation of the radial centrifugal force, in addition, because the fork thrust separation lever reaction force is not in the same line, but also form a torsion moment.Clutch separation bearing working conditions are poor, intermittent high-speed rotation and high speed friction, high temperature, poor lubrication conditions, no cooling conditions.

3, clutch separation bearing unit tolerance

1) The single inner diameter deviation of the bearing unit shall be specified in Table 3-2.2) The single diameter deviation of the contact circle △ D1s is ± 0.5mm.3), single diameter deviation of the connecting groove △ D2S is: upper limit: 0 mm, lower limit: -0.30 mm.4), the actual embedded deviation △ Hs with the classification fork is: upper limit: 0 mm, lower limit: -0.30 mm.5), in the case of no axial load, the actual fit width deviation of bearing unit △ TOS: push bearing unit is ± 0.5mm, pull bearing unit is ± 0.8mm.

4. Failure form of clutch separation bearing

The main failure forms of clutch separation bearing are: separation bearing loose sleeve, bearing inner and outer ring separation steel ball scattered, separation bearing ball head and surface wavy (concave, convex) wear, separation bearing abnormal sound, separation bearing stuck.

5. Other special bearings

Other special bearings for automobiles mainly include tensioning wheel bearings, water pump shaft coupling bearings, steering shaft bearings and steering gear bearings in some steering systems, as well as some bearings in manual transmission and main reducer.
