Description

Technical Field

[0001] The utility model belongs to the technical field of an automobile inner ball cage retainer, and more specifically, particularly relates to a durable automobile inner ball cage retainer. Background Art

[0002] The ball cage generally refers to the constant velocity universal joint. The ball cage in the car is connected to the differential part of the gearbox. The ball cage in the car is generally composed of a bell-shaped case, a cage, a tripod bearing and a steel ball. The cage is used to limit the rolling of the steel ball and can be used to withstand large centrifugal force, impact and vibration, so that the steel ball always remains within the appropriate range.

[0003] The existing application number is: CN202220842790.8. The utility model relates to the technical field of ball cage retainers, and in particular to a durable automobile inner ball cage retainer, comprising a frame body, a bottom ring body fixedly mounted at the bottom of the frame body, a plurality of notches distributed in a circumferential array are provided on the frame body, the notches penetrate the frame body, grooves are provided on both sides of the notches, buffer blocks are inserted in the grooves, a plurality of second springs distributed in a circumferential array are fixedly connected to the bottom of the annular movable bar, and the lower ends of the second springs are fixedly connected to the bottom of the annular slot. The utility model arranges a plurality of buffer blocks inside the frame body, and the inner wall of the bell-shaped shell contacts the plurality of buffer blocks when it is active and drives the buffer blocks to slide along the grooves, and the first spring is compressed, which can replace the frame body to directly contact the inner wall of the bell-shaped shell when the frame body is working to avoid direct contact between the frame body and the inner wall of the bell-shaped shell, greatly extending the service life of the main body, and there is no need to replace the frame body as a whole.

[0004] Based on the above, the retaining frame in the ball cage inside the car will produce friction with the steel ball during use. After a certain period of use, the outer surface of the steel ball is prone to some scratches due to friction, which causes the friction between the steel ball and the retaining frame to increase when rolling, thereby affecting the normal use of the ball cage inside the car. Therefore, it is necessary to replace the steel ball with scratches on the surface. The retaining frame is usually integrally formed during manufacturing, and the steel ball fits tightly to the inner circumference of the retaining frame. Therefore, it is more difficult to take the steel ball out of the inner circumference of the retaining frame, affecting the efficiency of replacing the steel ball. Utility Model Content
