2019-11-09 10:25:00

During the use of the servo planetary reducer , its gears often wear prematurely and do not reach the wear life that the gear should have. We call it abnormal wear. There are many reasons for abnormal wear of the servo planetary reducer. The main reasons are: The reasons are as follows, let's take a look together!
1. The manufacturing quality causes abnormal wear of the gears of the servo planetary reducer. The main quality problems are whether to choose the appropriate steel, the quality of the gear is not good, the quenching hardness is low, the gear hardness is not easy to bend and wear, the nodularization is not enough, and the use time Fatigue damage due to alternating stress.
2. The forging process used is not good, which causes defects such as trachoma, porosity and looseness, and insufficient nodulization.
3. The heat treatment process is not good, or the heat treatment is not performed, resulting in insufficient hardness of the reducer gear.
4. The gear design is unreasonable or the two gears do not match, resulting in the gear meshing accuracy and motion accuracy not meeting the requirements.
