The use and operation of planetary reducer is transmitted through the meshing force between gears. In the design process of planetary reducer, we should not only analyze whether the performance of materials is consistent with the current working conditions of components, but also analyze the economy of materials to ensure that materials are easy to manufacture. So as to improve the production efficiency of parts and reduce the operation cost and unnecessary loss of enterprises. If the gear material is not suitable, it will lead to premature wear of parts and even can not be used. So what technical requirements should planetary reducer gear materials meet?

1. Mechanical performance requirements of materials: the mechanical system performance of materials mainly includes hardness, strength and other indicators, reflecting the characteristics displayed by materials in use. There are still different contact stresses when the tooth surface of the gear is in contact during meshing. There are great differences at the root of the gear, which will affect the maximum bending stress, which may lead to the failure of the tooth surface. The points on the tooth surface may have comparative sliding and even serious wear. Therefore, the gear material should maintain a high bending fatigue strength and contact fatigue strength, the tooth surface should have sufficient hardness and wear resistance, and the core should have certain strength and toughness.

2. Processing technology requirements of materials: the process performance of materials refers to that the materials themselves can better adapt to the requirements of additional economy, that is, the cost is the lowest, so as to obtain the maximum benefit. The manufacturing of gears requires forging, cutting and heat treatment, so the selection of materials should pay attention to its process performance.

3. Material and economic requirements: in order to meet the functional requirements, we must also consider how to reduce the manufacturing cost of planetary reducer gears.

The above is an introduction to the technical requirements of planetary reducer gear materials. Those who need planetary reducer are welcome to consult the manufacturer of Newgear.
