Description

Technical Field

[0001] This utility model relates to the field of bearing disassembly and assembly tooling technology, specifically to a special bearing disassembly and assembly tooling. Background Technology

[0002] Bearings, as core components in mechanical equipment, bear the crucial responsibility of supporting rotating shafts or moving parts, and significantly reducing friction and wear generated during their operation. They not only ensure the smooth and stable operation of rotating components but also effectively improve mechanical efficiency and extend equipment lifespan. They play a vital and indispensable role in many key fields such as industrial production, transportation, and aerospace.

[0003] Based on the shape of the rolling elements, bearings can be further classified into various types, including deep groove ball bearings, cylindrical roller bearings, tapered roller bearings, self-aligning ball bearings, and thrust ball bearings. Among them, tapered roller bearings, with their excellent ability to withstand both radial and axial loads simultaneously, are widely used in equipment such as cranes.

[0004] In the current process of repairing and disassembling tapered roller bearings on cranes, it is frequently encountered that the bearing mounting hole is not a through hole, but rather has a dust cover at one end (integrated with the bearing housing). The inner hole is slightly larger than the bearing's inner diameter, and the clearance between the inner hole and the outer ring of the bearing is very small, making disassembly still very difficult. The only option is to use a hot knife to cut it off, but this is difficult, time-consuming, and labor-intensive, and there is a risk of cutting the bearing housing, causing unnecessary trouble during assembly. Therefore, we propose a special bearing disassembly and assembly fixture to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a special bearing disassembly and assembly tool to solve the problem mentioned in the background art that, in the process of disassembling and repairing tapered roller bearings on existing cranes, the bearing mounting hole is not a through hole, but has a dust cover at one end (integrated with the bearing housing), the inner hole is slightly larger than the inner diameter of the bearing, and the gap between it and the outer ring of the bearing is very small, making disassembly still very difficult. It can only be removed by cutting with a hot knife, but cutting is difficult, time-consuming and laborious, and it is easy to cut the bearing housing, causing unnecessary trouble for assembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A special bearing assembly / disassembly fixture includes a clamping component, a clamping screw on the clamping component, a mounting plate at one end of the clamping component, a plurality of movable top block components uniformly rotatable around an axis on the side of the mounting plate near the clamping component, an adjusting rod component on the other side of the mounting plate, a pressure plate component on the top of the plurality of movable top block components, a plurality of connecting rods respectively through the movable top block components, and a fastening nut at one end of the adjusting rod component through the mounting plate;

[0008] The movable top block component includes an oblong top block, and a slider is fixedly connected to one bottom end of the oblong top block. The slider passes through the mounting plate and is fixedly connected to a limit plate.

[0009] Furthermore, the clamping component includes a clamping plate, and a plurality of guide rods are fixedly connected at even intervals around one side of the clamping plate along an axis.

[0010] Furthermore, the mounting plate is provided with multiple waist-shaped grooves that rotate uniformly around the axis, and the mounting plate is slidably connected to multiple guide rods.

[0011] Furthermore, the waist-shaped top block is slidably connected to one side of the mounting plate, the slider is slidably connected to the mounting plate inside the waist-shaped groove, the limiting plate is slidably connected to the other side of the mounting plate, the adjusting rod component includes an adjusting rotating block, an adjusting rod is fixedly connected to the bottom of the adjusting rotating block, one end of the adjusting rod passes through the mounting plate and is fixedly connected to a connecting rod fixing block, and the adjusting rod is rotatably connected to the mounting plate.

[0012] Furthermore, the tightening screw includes a screw rotating block, a threaded rod is fixedly connected to the bottom of the screw rotating block, the threaded rod passes through the tightening plate and is fixedly connected to a top block, the threaded rod is threadedly connected to the tightening plate, and the lower surface of the top block is in contact with the top of the adjusting rotating block.

[0013] Furthermore, one end of each of the connecting rods is rotatably connected to the connecting rod fixing block, and the other end of the connecting rod is rotatably connected to the limiting plate. The inner side of the fastening nut is threadedly connected to the adjusting rod.

[0014] Furthermore, the clamping plate component includes a clamping ring, and a plurality of clamping blocks are fixedly connected at even intervals around the bottom of the clamping ring along the axis. The lower surface of the clamping ring is in contact with the top of a plurality of waist-shaped top blocks, and the plurality of clamping blocks are fixedly connected to the mounting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model involves placing the mounting plate inside the inner ring of the bearing, rotating the adjusting block, which in turn rotates the connecting rod fixing block at the other end of the adjusting rod, thereby driving multiple connecting rods to pull the limiting plate. This causes the slider at the bottom of the limiting plate to slide along the waist-shaped groove on the mounting plate, further pushing out the waist-shaped top block. This allows multiple waist-shaped top blocks to be inserted into the gap between the bearing and the sealing cover, applying external force to push out the bearing and avoiding the need for a fire knife to cut it off, which would affect subsequent bearing assembly.

[0017] 2. This utility model, by setting a clamping component, allows the mounting plate to slide on multiple guide rods. The clamping plate is in contact with the outer side of the bearing seat. Rotating the screw rotating block drives the threaded rod to rotate, which in turn drives the top block to press against the adjusting rod component, further slowly pushing out the mounting plate. This allows multiple movable top block components to push out the bearing between the bearing and the sealing cover, facilitating the disassembly and assembly of the bearing and avoiding damage to the bearing seat during disassembly and assembly, which would affect the stability of the bearing in subsequent use.

[0028] The movable top block component 4 includes a waist-shaped top block 401, and a slider 402 is fixedly connected to one end of the bottom of the waist-shaped top block 401. The slider 402 passes through the mounting plate 3 and is fixedly connected to a limit plate 403.

[0029] The clamping component 1 includes a clamping plate 101, and a plurality of guide rods 102 are fixedly connected at even intervals around one side of the clamping plate 101. In this example, by setting the guide rods 102, the mounting plate 3 can slide stably along the plurality of guide rods 102, thereby ejecting the bearing.

[0030] The mounting plate 3 is provided with multiple oblong grooves 301 that rotate uniformly around its axis, and the mounting plate 3 is slidably connected to multiple guide rods 102. In this example, by providing oblong grooves 301, the movable top block component 4 can slide stably along the oblong grooves 301, thereby extending into the gap between the bearing and the sealing cover, and facilitating the ejection of the bearing.

In this example, by setting the fastening nut 8, the adjusting rod 502 can be fixed to the mounting plate 3, thereby fixing the adjusting rod component 5 and preventing it from rotating, which would cause the movable top block component 4 to loosen and affect the disassembly and assembly of the bearing.

[0033] The clamping plate component 6 includes a clamping ring 601. Multiple clamping blocks 602 are fixedly connected at even intervals around the bottom of the clamping ring 601 along its axis.

[0037] The clamping component 1 includes a clamping plate 101, and a plurality of guide rods 102 are fixedly connected at even intervals around one side of the clamping plate 101 along its axis.

[0038] The mounting plate 3 is provided with multiple waist-shaped grooves 301 that rotate evenly around the axis, and the mounting plate 3 is slidably connected to multiple guide rods 102.

[0041] Working principle: The top plate 101 is attached to the outside of the bearing seat. The screw rotating block 201 is rotated, which drives the threaded rod 202 to rotate, thereby driving the top block 203 to press against the adjusting rotating block 501. The screw rotating block 201 is continuously rotated, and the mounting plate 3 on the adjusting rod component 5 is slowly pushed out. The mounting plate 3 slides along multiple guide rods 102, thereby driving multiple movable top block components 4 to push out the bearing.
