Detailed Description
The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
Referring to fig. 1, a drawn cup needle roller and thrust ball combined bearing includes a drawn cup needle roller bearing 1 and a thrust ball bearing 2. The drawn cup needle roller bearing 1 includes an outer ring 11, a needle roller bearing holder 12, and a needle roller 13, the needle roller 13 is mounted in a raceway of the needle roller bearing holder 12, and a spring piece 14 abutting against the needle roller 13 is further provided in the raceway of the needle roller bearing holder 12. The thrust ball bearing 2 includes a steel ball bearing holder 21 and a steel ball 22.
As shown in FIG. 1, a mounting plane 23 extends outwards from the end of the drawn cup needle roller bearing 1, a flange 24 extends upwards from the outer circumference of the mounting plane 23, the steel ball bearing retainer 21 is mounted in the mounting plane 23 and the flange 24, a cover 3 covers one end of the thrust ball bearing 2 away from the drawn cup needle roller bearing 1, and the inner side wall of the cover 3 is attached to the outer side wall of the flange 24.
As shown in fig. 1, in order to improve the pretightening force of the drawn cup needle roller bearing 1 and make the thrust ball bearing 2 not easy to fall off, a gasket 4 is arranged between the cover 3 and the thrust ball bearing 2, the outer circumference of the gasket 4 is attached to the inner side wall of the flange 24, and the upper surface of the gasket 4 is flush with the upper end surface of the flange 24.
As shown in fig. 2, in order to further prevent the thrust ball bearing 2 from falling off, a rib 5 extends in the direction of the spacer 4 on the inner wall of the flange 24, and a step 6 abutting against the rib 5 is provided on the upper surface of the spacer 4. The side of the rib 5 facing the step 6 is provided with an inclined surface, the inclined surface is provided with a plurality of first saw teeth 51, and the step 6 is provided with second saw teeth 61 engaged with the first saw teeth 51. The flange 5 can resist the gasket 4, so that the gasket 4 is not easy to move axially, and the first sawteeth 51 and the second sawteeth 61 are meshed so that the gasket 4 is not easy to move axially and move radially, so that the pre-tightening force of the gasket 4 is improved.
As shown in fig. 2, in order to prevent the cover 3 from falling off from the drawn cup needle roller bearing 1, a connecting rod 7 is disposed on an end surface of the flange 24, a plurality of elastic members 71 are disposed on an end surface of the connecting rod 7 along a circumferential direction thereof, and a guide arc 72 is disposed on an end of each elastic member 71 away from the connecting rod 7.
