What role does the heat treatment process of DC geared motors
The reason why the performance of the DC geared motor can be fully exerted is that its heat treatment plays a certain role. In fact, the heat treatment of the equipment is to place metal materials in a certain medium to heat, keep and cool. By changing the surface of the material or The internal crystalline phase structure is a thermal processing technology to change the performance of the equipment. What specific heat treatment does the equipment use?
1. Stress Relief Annealing: The purpose is to eliminate casting force and improve mechanical properties and machining performance.
2. Graphitization annealing: If the cross-sectional size of the DC geared motor is relatively large, white openings are easy to form on thin sections. In this way, graphitization annealing must be performed. The purpose is to eliminate white openings.
3. Other materials: There are also aluminum alloy DC geared motors. The heat treatment is similar to that of cast iron and the purpose is similar, but important aluminum alloy parts need to be subjected to solution treatment aging in order to improve mechanical properties.
4. Homogenizing annealing: The more important DC geared motors or DC geared motors made of other cast iron materials, in order to improve the mechanical properties, homogenizing annealing is needed because many chemical composition segregation is formed during the casting process. The purpose is to uniformly organize and guarantee The cross-section mechanical properties are consistent, improving the mechanical properties.
