Many users in the use of drum gear coupling will have some wear phenomenon, so do you know what is the cause of this? How do we deal with it? Next, follow Xiaobian to learn about it: 1. Drum gear coupling lifting accessories coupling oil is insufficient or lack of oil. Or improper use of oil, resulting in oil calcification, resulting in tooth surface can not be lubricated, or lubrication is not good tooth surface wear serious, this situation as long as the replacement of new grease, regular injection of qualified grease oil, to prevent oil leakage, sufficient oil, can be avoided. 2. The levelness and coaxiality error of the two shafts of the drum gear coupling is too large, which exceeds the compensation range of the coupling, so that the shaft teeth and the inner teeth are not meshed correctly, resulting in local contact and additional torque. And this additional moment can be decomposed into axial forces. Acting on the inner gear ring, the size of the force depends on the size of the deviation, and is proportional to the deviation, the greater the deviation, the greater the force, resulting in the lifting accessories coupling inner gear ring axial displacement. If the displacement is too large, it can not be controlled, resulting in serious gear wear, even broken teeth, internal and external teeth can not mesh, until can not drive.
