Embodiment 1

[0040] Please refer to figure 1 and figure 2 , this embodiment provides a bearing seal cover 100 , including a snap ring 110 , a seal cover 120 and a locking ring 130 . The snap ring 110 and the locking ring 130 are respectively detachably connected to two ends of the sealing cover 120 .

[0041] Please refer to image 3 and Figure 4 The snap ring 110 includes a first annular body 111 and a first connecting piece 113 , and the first and last ends of the first annular body 111 are detachably connected by the first connecting piece 113 . Specifically, both ends of the first annular body 111 have a first protruding portion 115 extending outward, and the first protruding portion 115 is provided with a first through hole 117, through which the first connecting member 113 passes through the first through hole 117 for The first and last ends of the first annular body 111 are connected. Compared with the existing single ring structure, this structure avoids the high swing frequ...

Embodiment 2

[0050] Please refer to Figure 7 , the present embodiment provides a bearing sealing structure 200 based on the bearing sealing cover 100 , including the connecting rod 210 , the ball bearing 220 and the bearing sealing cover 100 . The end of the connecting rod 210 is provided with a groove 211 matching with the ball bearing 220. The ball bearing 220 includes a ball head 221 and a ball seat 223. Most of the ball head 221 is arranged in the groove 211 and is arranged in the groove. The part outside 211 is connected with the ball seat 223 . Both ends of the sealing cover 120 are detachably connected to the connecting rod 210 and the ball bearing 220 respectively.

[0051] A first annular groove 225 matching the first engaging portion 121 is formed on the outer surface of the ball head 223 near the end of the ball head 221 , and the first engaging portion 121 is engaged in the first annular groove 225 . Then the sealing cover 120 is connected with the ball bearing 220 through t...

Abstract

The invention provides a bearing seal cover and a bearing sealing structure and relates to the technical field of automobile steering. The bearing seal cover comprises a snap ring, a seal cover and alocking ring, wherein the snap ring comprises a ring body and a connecting part, and the front and tail ends of the ring body are detachably connected through the connecting part. One end of the sealcover is hermetically connected to the snap ring, and the locking ring is hermetically connected to the end, far from the snap ring, of the seal cover. According to the structure, the snap ring is ensured to be not stretched elastically, so that the bearing seal cover does not fall, and therefore, the sealing property is further guaranteed. The bearing seal cover is simple in structure and convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to the technical field of automobile steering, in particular to a bearing sealing cover and a bearing sealing structure. Background technique [0002] Bearings are common parts in mechanical equipment. In order to keep the bearings in good working condition, lubricants such as grease are usually filled in the bearings. If dust or dirt outside the bearing enters the bearing, or if the lubricant in the bearing leaks out of the bearing, the lubrication state in the bearing will be damaged, resulting in poor operation of the bearing and shortening the service life of the bearing. For this purpose, a sealing cage is usually provided in the structure of the bearing. By providing the sealing cover, the dust or dirt outside the bearing can be prevented from entering the bearing, and the lubricant in the bearing can be prevented from leaking out of the bearing. [0003] In the existing sealing cover, when the swing frequency of the ball ...
