Description
Definition:
The Thrust (Release) Bearing 631663 is a high-precision, heavy-duty component specifically designed for Claas agricultural machinery, such as combines and forage harvesters. It is a critical part of the clutch system, typically a single-use or non-regreasable unit, engineered to withstand the demanding conditions of agricultural operation.
Primary Functions:
-
Axial Load Management: Its core function is to handle significant axial (thrust) loads. These are forces applied parallel to the shaft’s axis, generated when the clutch pedal is depressed and the pressure plate’s diaphragm spring is engaged.
-
Clutch Disengagement: It acts as the direct interface for disengaging the clutch. When the clutch is actuated, the bearing is pushed against the rotating fingers of the pressure plate. This action releases the clamping force on the clutch disc, interrupting power transmission from the engine to the gearbox.
-
Motion Conversion: The bearing facilitates a critical conversion of motion. It translates the linear movement from the clutch release mechanism (e.g., hydraulic slave cylinder or mechanical linkage) into the rotational movement required to disengage the pressure plate.
-
Reducing Friction and Wear: By providing a smooth, low-friction surface between the stationary release mechanism and the rotating clutch components, it minimizes wear on both the pressure plate and the release fork, ensuring smooth operation and longevity of the clutch system.
