Description

Technical Field

[0001] The invention belongs to the field of bearing manufacturing, and mainly relates to a separation tool for outer components of a thin-walled cylindrical roller bearing. Background Art

[0002] The structural form of the outer components of thin-walled cylindrical roller bearings makes it impossible to separate the outer ring, cylindrical roller and solid cage by conventional means, and thus it is impossible to check the status and dimensional accuracy of the bearing cage, outer ring guide surface and outer ring raceway. Currently, they can only be disassembled by cutting the outer ring or cage, resulting in the inability to detect technical parameters such as the outer ring raceway waveform, roundness, residual compressive stress, etc. after disassembly. Summary of the invention

[0003] The purpose of the present invention is to solve the problem that the outer ring of a cylindrical roller bearing needs to be destroyed and the retainer cut to split the outer components, but the outer ring accuracy cannot be retained, and to provide a thin-walled cylindrical roller bearing outer component separation tool.

[0004] The thin-walled cylindrical roller bearing outer component separation tool of the present invention comprises a thin-walled cylindrical roller, a bearing outer ring, a bearing inner ring and a support column;

[0005] The outer ring of the bearing is a "duckbill cap" type structure, and a through hole is arranged in the thin-walled cylindrical roller, and the support pillar is installed in the through hole.

[0006] Furthermore, a through hole is arranged in the thin-walled cylindrical roller, and the through hole is coaxial with the thin-walled cylindrical roller.

[0007] Furthermore, the outer ring of the bearing is a "duckbill cap" type structure, and the diameter of the cap top is smaller than the diameter of the inner ring of the bearing.

[0008] Furthermore, when removing the outer ring of the bearing, a lever is used to pry the outer ring of the bearing as the brim of a "duckbill cap" to separate the outer ring of the bearing from the thin-walled cylindrical roller and the pillar.

[0009] Furthermore, the lower surface of the bearing outer ring contacts the upper surface of the support column.

[0010] The present invention has the following beneficial effects:

[0011] The present invention adopts a "duckbill cap" type bearing outer ring. When separating, the lever applies force to pry the brim of the cap, so that the bearing outer ring can be separated. The present invention achieves separation of the outer components without destroying the rolling surface characteristics of the cylindrical roller after the test, the outer ring raceway waveform and surface characteristics, and other characteristics of the cage except the locking point.

[0016] Example

[0017] Analysis of structural characteristics of thin-walled cylindrical roller bearings

[0018] Thin-walled cylindrical roller bearings have the characteristics of thin ring wall thickness and small cylindrical roller size. Based on this, the thin-walled cylindrical roller bearing outer component separation tooling of this embodiment includes a thin-walled cylindrical roller 1, a bearing outer ring 2, a bearing inner ring 3 and a support 4; the bearing outer ring 2 is a "duckbill cap" type structure, and a through hole is provided in the thin-walled cylindrical roller 1, and the support 4 is installed in the through hole. A through hole is provided in the thin-walled cylindrical roller 1, and the through hole is coaxial with the thin-walled cylindrical roller 1. The diameter of the cap top of the bearing outer ring 2, which is a "duckbill cap" type structure, is smaller than the diameter of the bearing inner ring 3. The lower surface of the bearing outer ring 2 is in contact with the upper surface of the support 4.

[0019] When disassembling the bearing outer ring 2, use a lever to pry the bearing outer ring 2 as the brim of a "duckbill cap" to separate the bearing outer ring 2 from the thin-walled cylindrical roller 1 and the support 4.

[0020] The thin-walled cylindrical roller bearing outer component separation tool of this embodiment has the following advantages:

[0021] (1) The tooling should be easy to fix, and the clamping device should reduce damage to the end face of the cylindrical roller;

[0022] (2) Do not damage the outer ring and cage;

[0023] (3) The bearing outer ring 2 can be separated by applying force on the lever.
