Drum-shaped gear coupling is a key equipment for energy saving.Sometimes there will be some failures, as follows:
1. Insufficient lubrication or dry grinding;
2. The oil is not clean;
3. The center deviation of the drum gear coupling is too large, and the relative displacement of the tooth surface is large;
4. Poor oil quality, which contains acids or sulfides, etc.;
5. Excessive installation interference causes the tooth head clearance to disappear;
6. Poor material and low tooth surface hardness;
7. The tooth profile design of the drum gear coupling is not reasonable enough, the tooth top interferes or the machining accuracy is not high.
