Description

Technical Field

[0001] This utility model relates to the field of plastic cage technology for rotary bearings, specifically a plastic cage for rotary bearings that reduces vibration and noise. Background Technology

[0002] A plastic bearing cage is a part used in bearings. Its main function is to partially enclose all or part of the rolling elements and move with them, thereby isolating the rolling elements, guiding them to move on the correct track, and holding them within the bearing.

[0003] In traditional bearings with plastic cages, the bearing is usually housed within the inner wall of the cage, which helps stabilize the bearing rotation. However, traditional methods rely solely on the plastic cage itself for vibration damping, which reduces the bearing's damping efficiency. Furthermore, the traditional bearing is prone to wear and tear when rotating within the plastic cage for extended periods, generating noise and affecting the bearing's stable rotation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a shock-absorbing and noise-reducing plastic bearing cage to solve the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a shock-absorbing and noise-reducing plastic retainer for a rotating bearing, comprising a main ring 1, a bearing body movably sleeved on the inner wall of the main ring 1, an outer ring provided on the outer edge of the main ring 1, and the inner wall of the outer ring movably sleeved on the outer edge of the bearing body, an inner ring provided on the inner wall of the main ring 1, and the inner wall of the inner ring movably sleeved on the outer edge of the bearing body, a main ring 2 overlapping on the side of the main ring 1, and the inner wall of the main ring 2 movably sleeved on the outer edge of the bearing body, a U-shaped plate overlapping on the side of the main ring 1, an auxiliary plate overlapping on the side of the U-shaped plate, and the inner wall of the auxiliary plate overlapping on the side of the main ring 2, a limiting rod slidably sleeved on the inner wall of the main ring 1, and the outer edge of the limiting rod passing through the inner wall of the U-shaped plate and slidably sleeved on the inner walls of the main ring 1, the main ring 2, and the auxiliary plate.

[0006] As a preferred embodiment of this utility model, a spring is fixedly connected to the side of the inner wall of the limiting rod, and a triangular block is fixedly connected to the end of the spring away from the inner wall of the limiting rod, and the side of the triangular block is in close contact with the side of the auxiliary plate.

[0007] As a preferred embodiment of this utility model, the outer edge of the outer ring and the inner wall of the inner ring are both provided with slots, and arc-shaped shock-absorbing plates are fixedly mounted on both sides of the inner wall of the U-shaped plate. Rubber pads are fixedly mounted on the sides of the arc-shaped shock-absorbing plates, and the sides of the rubber pads are slidably connected to the inner wall of the slots.

[0008] As a preferred technical solution of this utility model, the inner walls of both the first main ring and the second main ring are provided with drum-shaped grooves, and an oil inlet groove is provided on the side of the drum-shaped groove closest to the first main ring.

[0009] As a preferred embodiment of this utility model, there are two outer rings and two inner rings, and the inner walls of the two adjacent outer rings are in contact with each other. The connection structures of the two outer rings' sides are completely identical, and the connection structures of the two inner rings' inner walls are completely identical.

[0010] As a preferred embodiment of this utility model, there are two triangular blocks, and the sides of the two triangular blocks are slidably connected to the inner walls of the limiting rod near both sides, and the connection structures of the sides of the two triangular blocks are completely identical.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The vibration-damping and noise-reducing plastic cage of the bearing uses the cooperation of the outer ring and the inner ring, and the main ring one and the main ring two are used to move the bearing body. Then, the outer ring and the inner ring are used to limit the bearing body and thus assist the bearing body to move. Then, the arc-shaped damping plate and the rubber pad are used to assist the movement of the outer ring and the inner ring, thereby reducing the vibration of the bearing body.

[0013] 2. The vibration-damping and noise-reducing plastic bearing cage uses a combination of a drum-shaped groove and an oil inlet groove. The oil inlet groove assists the main ring 1 in receiving oil. Then, the outer edge of the bearing body rotates within the inner walls of the main ring 1 and main ring 2, thereby assisting the oil to flow within the inner wall of the drum-shaped groove. Subsequently, the oil flows steadily with the bearing body to the outer edge of the bearing body, thereby reducing bearing body wear and reducing noise.

[0014] 3. The shock-absorbing and noise-reducing plastic retainer for the rotating bearing, through the cooperation of the limiting rod and the U-shaped plate, allows the outer edge of the limiting rod to slide through the inner wall of the U-shaped plate and slide into the inner walls of the first main ring, the second main ring, and the auxiliary plate. Then, the spring pushes the triangular block to move, and the side of the triangular block is in close contact with the side of the auxiliary plate. Thus, the inner wall of the limiting rod and the side of the triangular block assist the U-shaped plate and the auxiliary plate in stably clamping and limiting the first main ring, the second main ring, the outer ring, and the inner ring.

[0024] Please see Figures 1-7A shock-absorbing and noise-reducing plastic bearing cage includes a main ring 1, a bearing body 2 movably sleeved on the inner wall of the main ring 1, an outer ring 3 disposed on the outer edge of the main ring 1, and the inner wall of the outer ring 3 movably sleeved on the outer edge of the bearing body 2, an inner ring 4 disposed on the inner wall of the main ring 1, and the inner wall of the inner ring 4 movably sleeved on the outer edge of the bearing body 2, a main ring 2 15 overlapping the side of the main ring 1, and the inner wall of the main ring 2 movably sleeved on the outer edge of the bearing body 2, a U-shaped plate 7 overlapping the side of the main ring 1, an auxiliary plate 8 overlapping the side of the U-shaped plate 7, and the inner wall of the auxiliary plate 8 overlapping the main ring 2 15. The sides overlap, and the inner wall of the main ring 1 slides and is fitted with a limiting rod 9. The outer edge of the limiting rod 9 passes through the inner wall of the U-shaped plate 7 and slides and is fitted with the inner wall of the main ring 1, the inner wall of the main ring 2 15, and the inner wall of the auxiliary plate 8. Through the cooperation of the outer ring 3 and the inner ring 4, the outer ring 3 and the inner ring 4 are used to assist in limiting the movement of the bearing body 2 as the main ring 1 moves. Through the cooperation of the U-shaped plate 7 and the auxiliary plate 8, the U-shaped plate 7 and the auxiliary plate 8 are used to assist in fixing the main ring 1 and the main ring 2 15, thereby ensuring that the inner walls of the main ring 1 and the main ring 2 15 assist in the stable rotation of the bearing body 2.

[0025] In a preferred embodiment, a spring 10 is fixedly connected to the side of the inner wall of the limiting rod 9, and a triangular block 11 is fixedly connected to the end of the spring 10 away from the inner wall of the limiting rod 9. The side of the triangular block 11 is in close contact with the side of the auxiliary plate 8. Through the cooperation of the spring 10 and the triangular block 11, the spring 10 pushes the triangular block 11 to move on the inner wall of the limiting rod 9, thereby making the side of the triangular block 11 in close contact with the side of the auxiliary plate 8, thus helping the main ring 1 and the main ring 2 15 to be stably and tightly attached.

[0026] In a preferred embodiment, slots 14 are provided on the outer edge of the outer ring 3 and the inner wall of the inner ring 4. Arc-shaped damping plates 12 are fixedly mounted on both sides of the inner wall of the U-shaped plate 7. Rubber pads 13 are fixedly mounted on the sides of the arc-shaped damping plates 12, and the sides of the rubber pads 13 are slidably connected to the inner wall of the slots 14. Through the cooperation of the arc-shaped damping plates 12 and the rubber pads 13, both of which are made of rubber, the arc-shaped damping plates 12 and the rubber pads 13 are used to assist the outer ring 3 and the inner ring 4 in shock absorption movement.

[0027] In a preferred embodiment, both the inner walls of the main ring 1 and the main ring 2 are provided with drum-shaped grooves 5, and the drum-shaped groove 5 is provided with an oil inlet groove 6 on the side near the main ring 1. Through the cooperation of the drum-shaped groove 5 and the oil inlet groove 6, the inner wall of the oil inlet groove 6 assists in adding external lubricating oil into the inner cavity of the drum-shaped groove 5. Then, during the rotation of the outer edge of the bearing body 2 on the inner wall of the drum-shaped groove 5, the lubricating oil is driven to flow, thereby covering the outer edge of the bearing body 2.

[0028] In a preferred embodiment, there are two outer rings 3 and two inner rings 4, and the inner walls of two adjacent outer rings 3 are in contact with each other. The connection structure of the sides of the two outer rings 3 is completely identical, and the connection structure of the inner walls of the two inner rings 4 is completely identical. By using the two outer rings 3 and the two inner rings 4 together, the sides of the two outer rings 3 are in contact with each other, and the sides of the two inner rings 4 are in contact with each other, thereby limiting the outer edge of the bearing body 2.

[0029] In a preferred embodiment, there are two triangular locking blocks 11, and the sides of the two triangular locking blocks 11 are slidably connected to the inner walls of the limiting rod 9 near both sides. The connection structure of the sides of the two triangular locking blocks 11 is completely identical. By adding the two triangular locking blocks 11, the sides of the two triangular locking blocks 11 can move towards each other in the inner wall of the limiting rod 9, and the sides of the two triangular locking blocks 11 can be used to assist the U-shaped plate 7 and the auxiliary plate 8 to be stably and tightly attached.

[0030] Working principle: When the device is in use, the main ring 1 and main ring 2 movably engage the bearing body 2. Then, the outer ring 3 and inner ring 4 assist in limiting the bearing body 2, thereby assisting the bearing body 2 to move. Next, the arc-shaped damping plate 12 and rubber pad 13 assist the outer ring 3 and inner ring 4 to move, thus damping the bearing body 2. The outer edge of the limiting rod 9 passes through the inner wall of the U-shaped plate 7 and slides against the inner walls of the main ring 1, main ring 2 15, and auxiliary plate 8. Then, the spring 10 pushes the triangular locking block 11 to move, and the triangular locking block 11... The side of the bearing 1 is in close contact with the side of the auxiliary plate 8, so that the inner wall of the limiting rod 9 and the side of the triangular block 11 assist the U-shaped plate 7 and the auxiliary plate 8 to stably clamp and limit the main ring 1, main ring 2 15, outer ring 3 and inner ring 4. The oil inlet groove 6 assists the inner cavity of the main ring 1 to enter the oil. Then, the outer edge of the bearing body 2 rotates in the inner wall of the main ring 1 and main ring 2 15, so that the auxiliary oil flows in the inner wall of the drum groove 5. Then, the auxiliary oil rolls with the bearing body 2 and flows stably to the outer edge of the bearing body 2, thereby reducing the wear of the bearing body 2 and reducing the noise of the bearing body 2.
