Abstract
The utility model discloses an axial thrust bearing for an automobile clutch, comprising an upper thrust sheet and a lower thrust sheet, wherein a rolling body is connected between the upper thrust sheet and the lower thrust sheet in a rolling way. A cage is also arranged between the upper thrust sheet and the lower thrust sheet, and provided with a ball pocket. The rolling body is arranged in the ball pocket. The wall of the ball pocket forms a spherical pocket shape, and the spherical surface is matched with that of the rolling body. The cage is made form reinforced nylon. The peripheries of the upper thrust sheet and the lower thrust sheet are also provided with outer casings. As the wall of the ball pocket forms the spherical pocket shape, the rolling body is placed into the ball pocket, both ends of the rolling body are respectively butted with the upper and lower thrust sheets and rotate opposite to each other, and the cage is held in the center of the rolling body, and cannot generate friction with the lower thrust sheet when moving to the direction of the lower thrust sheet due to gravity or other reasons, so the precision and service life of the bearing are ensured.
Description
Technical field
The utility model relates to a kind of axial thrust bearing, particularly relates to the axial thrust bearing that a kind of automobile clutch is used.
Background technique
Existing automobile clutch is mainly gone up thrusting plate and following thrusting plate with axial thrust bearing and is placed, several rolling elements between the following thrusting plate, rolling element and last, following thrusting plate is rotatably connected, in order to prevent the certain distance between the rolling element, axial thrust bearing also must be provided with retainer, retainer is a diameter and last, the suitable circle of following thrusting plate, at the first-class branch setting of the circle axial circular hole identical with rolling element quantity, the diameter and the rolling element of circular hole are complementary, during Bearing Installation rolling element is put into circular hole, like this, when bearing is transported, rolling element with on, when relatively rotating, following thrusting plate can not influence the precision of bearing each other because of the mutual friction of contact phase.But, adopt the automobile clutch axial thrust bearing of this form retainer, in the bearing rotation process, install because bearing is vertical usually, retainer downward thrusting plate direction under the effect of gravity moves, make between rolling element and the circular hole gap takes place, cause steel ball to skid, influence the precision of bearing, in addition, because retainer contacts with following thrusting plate, cause retainer and following thrusting plate to rub, and strengthened the frictional resistance of bearing, and simultaneously, because of friction also can cause local pyrexia even wearing and tearing.
The model utility content
For overcoming above-mentioned defective, the utility model aims to provide the automobile clutch axial thrust bearing that a kind of retainer can not contact with the thrusting plate friction.
For achieving the above object, the technological scheme that the utility model provides is: the axial thrust bearing that a kind of automobile clutch is used, comprise thrusting plate and following thrusting plate, the described rolling element that has been rotatably connected between thrusting plate and the following thrusting plate of going up, described going up between thrusting plate and the following thrusting plate also has retainer, and described retainer is provided with ball pocket hole, and described rolling element places in the ball pocket hole, the hole wall in described ball pocket hole is the sphere pocketed, and the sphere of described hole wall and the sphere of rolling element are complementary.
The material of described retainer is a nylon.
Also be provided with shell on the periphery of described upward thrusting plate and following thrusting plate.
The axial thrust bearing that has adopted automobile clutch of the present utility model to use, because the hole wall in ball pocket hole is the sphere pocketed, during assembling, after pushing rolling element in the goal pocket hole, between rolling element and the retainer just displacement can not appear, be rolling element by pocket in ball pocket hole, like this, when two ends of rolling element contact and relatively rotate with upper and lower thrusting plate respectively, retainer remains on the central position of rolling element, can not rub, guarantee the precision and the working life of bearing because of gravity or the downward thrusting plate direction of other reason move with following thrusting plate.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing in ball pocket of the present utility model hole.
Among the figure: the last thrusting plate of 1-, thrusting plate under the 2-, 3-rolling element, 4-retainer, 5-ball pocket hole, 6-hole wall, 7-shell.
Embodiment
As depicted in figs. 1 and 2, the utility model discloses the axial thrust bearing that a kind of automobile clutch is used, comprise thrusting plate 1 and following thrusting plate 2, the described rolling element 3 that has been rotatably connected between thrusting plate 1 and the following thrusting plate 2 of going up, described going up between thrusting plate 1 and the following thrusting plate 2 also has retainer 4, described retainer 4 is provided with ball pocket hole 5, the hole wall 6 in ball pocket hole 5 is a cylindrical shape, described rolling element 3 places in the ball pocket hole 5, in sum, the axial thrust bearing basically identical of using with existing car clutch is when bearing working, retainer 4 easily downward thrusting plate 2 directions under the effect of gravity move, and cause rubbing between retainer 4 and the following thrusting plate 2.
Main innovate point of the present utility model is that the hole wall 6 in described ball pocket hole 5 is the sphere pocketed, and the sphere of the sphere of described hole wall 6 and rolling element 3 is complementary.During assembling, after pushing rolling element 3 in the goal pocket hole 5, between rolling element 3 and the retainer 4 just displacement can not appear, be rolling element 3 by pocket in ball pocket hole 5, like this, when two ends of rolling element 3 contacted and relatively rotate with upper and lower thrusting plate 1,2 respectively, retainer 4 remained on the central position of rolling element 3, can not rub, guarantee the precision and the working life of bearing because of gravity or downward thrusting plate 2 directions of other reason move with following thrusting plate 2.
Because the hole wall 6 in ball pocket hole 5 is the sphere pocketed, two aperture positions that are ball pocket hole 5 are slightly littler than the diameter of rolling element 3, like this, after pushing rolling element 3 in the goal pocket hole 5 during the bearing assembling, rolling element 3 just can remain in the ball pocket hole 5 and not be subjected to displacement with ball pocket hole 5, the material of described retainer 4 must both have certain intensity, has certain elasticity again, so, the material of described retainer 4 of the present utility model can be high-strength nylon, in actual applications, the material that adopts usually is a reinforced nylon 66.Can certainly adopt both to have had certain intensity, have certain flexible other material again, not remake here one by one and introduce.
In order to protect bearing, also be provided with shell 7 on the periphery of described upward thrusting plate 1 and following thrusting plate 2.Usually one of them in shell 7 and last thrusting plate 1 and the following thrusting plate 2 fixed, and another then can relatively rotate with shell 7.
