Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a heating device with a fixed structure. Background Art

[0002] In the heat treatment process, rolling bearings need to be tempered after quenching to ensure their strength. Sliding bearings are cast and do not require heat treatment. Rolling bearings usually use low-temperature tempering. The purpose is to maintain the high hardness and high wear resistance of the quenched steel while reducing the quenching internal stress and brittleness to prevent cracking or premature damage during use.

[0003] According to a disclosed rapid heating device for bearing heat treatment (publication number: CN215799714U), the above application includes a heating drum, a heating plate, a rotating shaft and a motor. There is a heating cavity in the heating drum, two heating plates are symmetrically installed on the cavity wall, the rotating shaft is connected to the lower surface of the heating drum, and the motor that drives it to rotate is located in the installation cavity in the base.

[0004] However, during actual use of the above-mentioned heating device, although the heating drum rotates and promotes the uniform distribution of hot air flow, the positions of the heating plate and the bearing are still relatively fixed. Some parts of the bearing will be directly heated, while other parts will not be fully heated, resulting in inconsistent heat treatment effects on the bearing, affecting its ultimate performance and quality. In view of this, we propose a heating device with a fixed structure. Utility Model Content
