What heat treatment is used in DC geared motors
The key to the performance of the DC geared motor is that its heat treatment prays for a certain effect. 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? The following knowledge will be introduced in detail.
1. Stress Relief Annealing: The purpose is to eliminate casting force and improve mechanical properties and machining performance.
2. Graphitizing annealing: If the cross-sectional size difference of the DC brushless gear motor is relatively large, it is easy to form white mouth on the thin section, so the graphitizing annealing must be performed, the purpose is to eliminate the white mouth.
3. Other materials: There are also aluminum alloy DC brushless 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. Homogenization annealing: The more important DC brushless geared motors or DC brushless geared motors made of other cast iron materials, in order to improve the mechanical properties, homogenization annealing is needed, because a lot of chemical composition segregation is formed during the casting process. Organization to ensure consistent mechanical properties of each section and improve mechanical properties.
