2. Bearing wear nothing. 
3. The bearing installation of large amount of bad or shaft bunches of low (especially for processing precision of herringbone gear) 4. The gear wear and tear or lubricating oil dirty and lack of lubricating oil. 
5. The meshing of gear, gear radial or axial runout is too large. 
6. Big gear coupling screw loosening or counterpart screw loose. 
7. The gear machining accuracy don't meet requirement. 
Second, why ball mill gear tooth surface wear too fast? 
1. The poor lubrication 
2. The meshing clearance is too large or too small contact isn't good 
3. The quality of gear cutting out requirements (such as tooth profile, radial and axial runout, heat treatment) 4. 5. Poor material ball mill gear assembly is not reasonable 
6. Teeth into the sand 
Three, ball mill transmission shaft and the bearing coupling bolt fracture.
