1. The tooth profile design of the drum-shaped gear coupling is not reasonable enough, the tooth top interferes or the machining accuracy is not high;
2. The center deviation of the drum gear coupling is too large, and the relative displacement of the tooth surface is large;
3. Insufficient lubrication or dry grinding;
4. Poor material and low tooth surface hardness;
5. Poor oil quality, acid or sulfide in the oil, etc.;
6. Excessive installation interference causes the tooth head clearance to disappear;
7. The oil is not clean.
In order to avoid these failures, we should pay attention to the above points when using or installing, so that the mechanical system can work smoothly.
