Abstract
The utility model discloses a release bearing and belongs to the field of bearings. The defects that the conventional automobile clutch release bearing cannot automatically restore to an initial state after self-aligning, the secondary automatic self-aligning is difficult and a self-aligning spring is easy to damage are overcome. The release bearing comprises an outer ring, an inner ring, rollers, a sealing piece, a retainer, a self-aligning spring, a shaft sleeve, a base and a return spring, wherein the rollers are uniformly separated and fixed on the retainer; the outer ring is set to be in a disc shape in the center of which a hole is reserved; the inner ring is pressed against the inner end face of the outer ring through the retainer and the rollers; the end face of the other sides of the inner ring and the outer ring is provided with the sealing piece; two ends of the self-aligning spring are respectively pressed against the inner end face of the outer ring and a stepped surface of the shaft sleeve; the base is embedded in a groove of the shaft sleeve; the disc-shaped bottom of the outer ring is attached to the end face of the base; the return spring is sleeved on the outer ring; and an outer ring side of the return spring is pressed against the end face of the base. By the release bearing, the overall structure is simplified, and the manufacturing cost is reduced.
Description
Technical field
The utility model belongs to field of bearings, especially with a kind ofly return to reset condition automatically, be prone to carry out the secondary self-aligning and the non-damageable release bearing of aligning spring is relevant.
Background technique
Vehicle clutch disengaging bearing is one of main accessory in the car transmissions; Be installed between clutch and the speed changer; It can make separator levers rotate an edge clutch output shaft on one side and move axially, thereby it is smooth-going to have guaranteed that clutch can engage, and separates soft; Reduce wear, prolong the working life of clutch and whole drive unit.Most of vehicle clutch disengaging bearings adopt the aligning spring that speed changer and clutch are rotated with one heart; Yet receive radial load owing to just rely on the aligning spring to pass; Be prone to make the aligning spring to damage, need change release bearing frequently, increased the maintenance cost of automobile.
The model utility content
The purpose of the utility model be for overcome existing vehicle clutch disengaging bearing exist can not restPose automatically, secondary self-aligning difficulty and the flimsy defective of aligning spring, provide a kind of and can return to reset condition automatically, be prone to carry out secondary self-aligning, the non-damageable release bearing of aligning spring.
For this reason, the utility model adopts following technological scheme: a kind of release bearing comprises outer ring, inner ring, roller, Sealing, retainer, aligning spring and axle sleeve; The even spaced fixed of roller will make roller in moving process, remain relative distance on retainer like this, and the plate-like of boxing out in the center is arranged in the outer ring; Inner ring is resisted against the outer ring interior edge face through retainer, roller, and the opposite side end face of inner ring and outer ring is provided with Sealing, can effectively avoid extraneous impurity to get in the bearing; Improved the working life of bearing widely; The two ends of aligning spring are resisted against respectively on the interior edge face and axle sleeve step surface of outer ring, do the time spent when release bearing receives eccentric force, and the aligning spring will make that release bearing and axle sleeve are concentric through self-deformation; It is characterized in that: described release bearing also comprises base and Returnning spring; Base is inlaid in the groove of said axle sleeve, and the plate-like bottom surface of said outer ring and base end face paste clothes, and Returnning spring is sleeved on the described outer ring; The outer rim side of Returnning spring is resisted against the end face of base; Returnning spring plays buffer function in release bearing self-aligning process, and clutch with can make release bearing return to reset condition after speed changer separates, guarantee that next self-aligning can carry out smoothly.
The beneficial effect that uses the utility model to reach: the radial displacement of the utility model through aligning spring and Returnning spring and stressed; Realize the self-aligning function of clutch release bearing; The wearing and tearing of clutch release bearing have been reduced; Increase the service time of release bearing widely, also reduced the cost of upkeep of automobile simultaneously; Simplify axle sleeve structure, reduced manufacture cost.

Embodiment
Be described in detail below in conjunction with the embodiment of accompanying drawing the utility model.
Like Fig. 1, shown in Figure 2, the utility model comprises outer ring 1, inner ring 2, roller 3, Sealing 4, retainer 5, aligning spring 6, axle sleeve 7, base 8 and Returnning spring, and roller 3 even spaced fixed are on retainer 5; Make roller 3 in moving process, remain relative distance; The plate-like of boxing out in the center is arranged in outer ring 1, and inner ring 2 is resisted against outer ring 1 interior edge face through retainer 5, roller 3, and inner ring 2 is provided with Sealing 4 with the opposite side end face of outer ring 1; The two ends of aligning spring 6 are resisted against respectively on the interior edge face and axle sleeve 7 step surfaces of outer ring 1; Do the time spent when release bearing receives eccentric force, aligning spring 6 will make release bearing concentric with axle sleeve 7 through self-deformation, in the groove of base 8 setting-in axle sleeves 7; The plate-like bottom surface of outer ring 1 and base 8 end faces paste clothes; Returnning spring is sleeved on the outer ring 1, and the outer rim side of Returnning spring is resisted against the end face of base 8, and Returnning spring plays buffer function in release bearing self-aligning process; And clutch with can make release bearing return to reset condition after speed changer separates, guarantee that next self-aligning can carry out smoothly.
