Description

Technical Field

[0001] This utility model belongs to the field of bearing technology, specifically relating to a bearing with a self-locking retaining ring. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy.

[0003] During the bearing manufacturing process, a self-locking retaining ring is usually installed on the inner ring of the bearing. Its function is to fix the bearing to the shaft and prevent the bearing from shifting axially. However, traditional self-locking retaining rings mainly rely on their own elasticity to lock into the inner ring. When the bearing rotates at high speed, the axial force on the retaining ring may exceed its elastic limit, causing the retaining ring to come off the inner ring. This will not only affect the normal operation of the bearing, but may also shorten its service life. Utility Model Content

[0004] The purpose of this invention is to provide a bearing with a self-locking retaining ring to solve the problem in the prior art where the axial force on the retaining ring may exceed its elastic limit when the bearing rotates at high speed, causing the retaining ring to come off the inner ring. This not only affects the normal operation of the bearing but may also shorten its service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bearing with a self-locking retaining ring includes an inner bearing ring and a retaining ring mounted on the outer wall of the inner bearing ring. The outer wall of the inner bearing ring has a groove, and the retaining ring is engaged inside the groove. One end of the retaining ring is provided with a engaging part, and the other end of the retaining ring is provided with a retaining seat part. The engaging part and the retaining seat part cooperate with each other to fix the retaining ring inside the groove.

[0007] Preferably, the snap-fit ​​part includes a first connecting block and a first locking block. One end of the retaining ring is fixedly connected to the first connecting block, and the end of the first connecting block that moves away from the retaining ring is fixedly connected to the first locking block. The end of the first locking block that moves away from the bearing is fixedly connected to a limiting hemisphere.

[0008] Preferably, the first locking block has a first abutting part at the end away from the first connecting block, and the first locking block, the first connecting block and the retaining ring have the same thickness and are located on the same plane.

[0009] Preferably, the card holder includes a second connecting block and a second locking connector, the other end of the retaining ring is fixedly connected to the second connecting block, the end of the second connecting block away from the retaining ring is fixedly connected to the second locking block, and the second locking block and the first locking block are engaged with each other.

[0010] Preferably, the second locking block has a second abutting part at the end away from the second connecting block, the second abutting part has a first limiting groove, and the second locking block has a second limiting groove at the end face near the retaining ring. The first limiting groove and the second limiting groove are connected and cooperate with the limiting hemisphere.

[0011] Preferably, the second connecting block has a third limiting groove and an inclined groove on one end face near the retaining ring. The third limiting groove and the inclined groove are connected. The limiting hemisphere is located inside the third limiting groove and is slidably connected to it. The thickness of the second connecting block and the second locking block is greater than the thickness of the retaining ring.

[0012] Preferably, the front end faces on both sides of the retaining ring are provided with disassembly and assembly holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model achieves fixation by engaging the retaining ring with the retaining seat at both ends. This design allows the retaining ring to rotate with the bearing at high speed. The fixing effect at both ends prevents the retaining ring from coming out of the inner ring due to axial force exceeding the elastic limit. This structure not only ensures the normal operation of the bearing, but also helps to extend its service life.

[0015] 2. This utility model achieves the installation process of the retaining ring through the mutual cooperation of the first limiting groove, the second limiting groove, the third limiting groove, the inclined groove, and the limiting hemisphere. During installation, the limiting hemisphere first enters the first limiting groove, then slides to the second limiting groove, and finally moves to the third limiting groove, thereby completing the engagement of the first locking block and the second locking block and fixing the retaining ring. When it is necessary to remove the retaining ring, the limiting hemisphere is moved by the second locking block, causing it to slide into the inclined groove and slide upward, thereby causing the first locking block to disengage from the second locking block and achieving the effect of removing the retaining ring.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-5 As shown, this utility model provides a bearing with a self-locking retaining ring, including an inner ring 1 and a retaining ring 2 mounted on the outer wall of the inner ring 1. A groove 11 is provided on the outer wall of the inner ring 1, and the retaining ring 2 is engaged inside the groove 11. One end of the retaining ring 2 is provided with a engaging part 21, and the other end is provided with a retaining seat part 22. The engaging part 21 and the retaining seat part 22 cooperate to fix the retaining ring 2 inside the groove 11. During operation, the retaining ring 2 is fixed by the engagement part 21 and the retaining seat part 22, allowing the retaining ring 2 to rotate with the bearing at high speed. The fixing effect at both ends prevents the retaining ring 2 from dislodging from the inner ring due to axial force exceeding its elastic limit. This solves the problem that when the bearing rotates at high speed, the axial force on the retaining ring 2 may exceed its elastic limit, causing the retaining ring 2 to dislodge from the inner ring, which would not only affect the normal operation of the bearing but also potentially shorten its service life.

[0024] In a further embodiment, refer to Figures 3-4The snap-fit ​​portion 21 includes a first connecting block 211 and a first snap-fit ​​block 212. One end of the retaining ring 2 is fixedly connected to the first connecting block 211, and the end of the first connecting block 211 moving away from the retaining ring 2 is fixedly connected to the first snap-fit ​​block 212. The end of the first snap-fit ​​block 212 away from the bearing is fixedly connected to a limiting hemisphere 214. The end of the first snap-fit ​​block 212 away from the first connecting block 211 is provided with a first abutment portion 213. The first snap-fit ​​block 212, the first connecting block 211, and the retaining ring 2 have the same thickness and are located on the same plane. The snap-fit ​​seat portion 22 includes a second connecting block 221 and a second snap-fit ​​connector. The retaining ring 2 also... A second connecting block 221 is fixedly connected to one end of the second connecting block 221. A second locking block 222 is fixedly connected to the end of the second connecting block 221 away from the retaining ring 2. The second locking block 222 is engaged with the first locking block 212. A second abutting part 223 is provided at the end of the second locking block 222 away from the second connecting block 221. A first limiting groove 224 is provided at the second abutting part 223. A second limiting groove 225 is provided at the end face of the second locking block 222 near the retaining ring 2. The first limiting groove 224 and the second limiting groove 225 are connected and cooperate with the limiting hemisphere 214. Disassembly holes 23 are provided on the front ends of both sides of the retaining ring 2.

[0025] In this embodiment, the pointed tip of the needle-nose pliers is inserted into the disassembly hole 23, and then the pointed tip is expanded to drive the two ends of the retaining ring 2 to move closer to each other. At this time, the first abutting part 213 and the second abutting part 223 are in contact with each other, and the first locking block 212 and the second locking block 222 continue to move, so that the first locking block 212 encounters the right side of the second locking block 222 and abuts against the right end face of the second locking block 222, thereby achieving the locking effect.

[0026] In a further embodiment, refer to Figure 5 The second connecting block 221 has a third limiting groove 226 and an inclined groove 227 on one end face near the retaining ring 2. The third limiting groove 226 and the inclined groove 227 are connected. The limiting hemisphere 214 is located inside the third limiting groove 226 and is slidably connected to it. The thickness of the second connecting block 221 and the second locking block 222 is greater than the thickness of the retaining ring 2.

[0027] In this embodiment, during installation, the limiting hemisphere 214 moves into the first limiting groove 224. During the movement of the first locking block 212 and the second locking block 222, the limiting hemisphere 214 slides in the first limiting groove 224 and then slides into the second limiting groove 225. The limiting hemisphere 214 moves into the third limiting groove 226, thus achieving the locking effect. Since the limiting hemisphere 214 slides inside the first limiting groove 224, the second limiting groove 225, and the third limiting groove 226, it can limit the movement of the first locking block 212. When it is necessary to disassemble the retaining ring 2, the first locking block 212 and the second locking block 222 are moved by needle-nose pliers, so that the limiting hemisphere 214 slides from inside the third limiting groove 226 into the inclined groove 227. When the movement distance is reached, the first locking block 212 and the second locking block 222 disengage, thereby expanding the inner diameter of the retaining ring 2, making it easier to remove the retaining ring 2 from the inner ring 1 of the bearing.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
