Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the directions or positional relationships indicated as the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., appear based on the directions or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" as appearing herein are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

The specific embodiment of the present invention is shown in fig. 1-5.

Fig. 1 shows a thrust ball bearing according to the present embodiment, which includes a shaft ring 03, a race 04, and a ball 02.

The embodiment is a thrust ball bearing retainer, adopts PA66 or PA64 injection moulding to form, and engineering plastics have for metal material that matter is light, intensity is high, coefficient of friction is little, the high performance such as machining efficiency is high, can bear higher mechanical stress and comparatively harsh service condition.

This embodiment includes the annular main part 01 and sets up the pocket 011 that supplies spin 02 to put into in the main part 01, the middle part of pocket 011 inner wall is sunken to the direction of keeping away from pocket 011 axis and makes whole inner wall be the drum type, the inner wall and the spin 02 butt of pocket 011, in this embodiment, the inner wall and the spin 02 laminating setting of pocket 011, the maximum aperture of pocket 011 equals spin 02's diameter, all be equipped with the boss that prevents spin 02 and break away from pocket 011 on the both ends face of main part 01, the boss is including setting up the interior boss 012 and the outer boss 013 of the radial arrangement along main part 01 between adjacent 02, there is the passageway spin 014 that supplies the circulation of lubricating oil between interior boss 012 and the outer boss 013.

After spin 02 embedding pocket 011, interior boss 012 and outer boss 013 and spin 02 butt, lock spin 02 in pocket 011, make spin 02 and pocket 011 only take place relative rotation in the time of actual operation, prevent that spin 02 from rocking in pocket 011, interior boss 012 and outer boss 013 components of a whole that can function independently set up, when guaranteeing interior boss 012 and outer boss 013 locking spin 02, reduce the contact surface of interior boss 012 and outer boss 013 and spin 02, reduce the frictional force of interior boss 012 and outer boss 013 and spin 02 in the time of actual operation, passageway 014 makes things convenient for the lubricant circulation, can balance the lubricant mass on each spin 02. This embodiment processing is convenient, and the finished product yields is high.

The height of the protruding main body 01 of the inner boss 012 and the outer boss 013 is less than the height of the protruding pocket 011 of the rolling ball 02, and the maximum distance between the opposite faces of the inner boss 012 and the outer boss 013 is less than the minimum aperture of the pocket 011. The height and width of the outer bosses 013 and the inner bosses 012 prevent the bosses from contacting the collar 03 and the race 04, and prevent the inner bosses 012 and the outer bosses 013 from affecting the normal operation of the thrust ball bearing.

The surfaces of the inner boss 012 and the outer boss 013 facing the rolling ball 02 are respectively provided with a limiting surface 015 attached to the rolling ball 02. Spacing face 015 can be better with spin 02 locking in pocket 011, prevent when the actual operation, spin 02 appears rocking and influences the operation of thrust ball bearing in pocket 011.

The surface of the inner boss 012 remote from the outer boss 013 is inclined toward the outer boss 013 from the side close to the main body 01 to the side remote from the main body 01, and the surface of the outer boss 013 remote from the inner boss 012 is inclined toward the inner boss 012 from the side close to the main body 01 to the side remote from the main body 01. When guaranteeing boss locking spin 02, reduce the contact surface of boss and spin 02, reduce the utility model discloses whole weight.

The utility model discloses do not confine the above-mentioned embodiment to, the general technical personnel in this field can adopt other multiple embodiments to implement according to the utility model discloses a, perhaps all adopt the utility model discloses a design structure and thinking do simple change or change, all fall into the utility model discloses a protection scope.
