Description

Technical Field

[0001] This utility model relates to the field of bearing heat treatment technology, and in particular to a bearing heat treatment device. Background Technology

[0002] Heat treatment is a metal heat treatment process that involves heating, holding, and cooling materials in a solid state to obtain the desired microstructure and properties.

[0003] 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. Depending on the frictional properties of the moving elements, bearings are mainly composed of an outer ring, an inner ring, rolling elements, and a cage.

[0004] In the bearing manufacturing process, in order to better assemble the bearing outer ring, a heat treatment process is generally used to heat the bearing outer ring, thereby increasing the inner diameter of the bearing outer ring.

[0005] Therefore, a bearing heat treatment device is proposed.

[0006] For example, the prior art Chinese patent publication number "CN222064623U" provides a bearing heat treatment device, including a worktable. Two support rods are fixedly connected to the top of the worktable. The top of the two support rods are fixedly connected to a conveying device. The conveying device includes a crossbar. A horizontal groove is opened at the bottom of the crossbar. A first threaded rod is rotatably connected between the inner walls of the two sides of the horizontal groove. A moving block is threaded onto the outer surface of the first threaded rod. One end of the first threaded rod passes through the horizontal groove and is fixedly connected to a main bevel gear. A secondary bevel gear is meshed with the outer surface of the main bevel gear. A connecting frame is fixedly connected to one end of the crossbar. A motor plate is fixedly connected to the lower inner wall of the connecting frame. A first motor is fixedly connected to the top of the motor plate. The output end of the first motor is fixedly connected to one end of the secondary bevel gear.

[0007] This device can effectively improve work efficiency by incorporating a conveyor system.

[0008] Existing bearing heat treatment equipment requires a fixed bearing placement position, which is inconvenient for heat treatment of bearings of different sizes. Furthermore, the bearings are prone to shaking during the heat treatment process, as the bearings are not properly secured. Additionally, the bearings may experience an increase in the inner diameter of the outer ring during heat treatment, which can easily lead to deformation of the bearing outer ring. The equipment also fails to provide stable support and abutment to ensure that the bearing outer ring increases in size uniformly. Utility Model Content

A second connecting hole is opened in the middle of the surface of the support plate, and a second bolt passes through the inside of the second connecting hole.
