Drum gear coupling four troubleshooting

At present we in the use of drum gear coupling in the process of whether to understand the coupling transmission parts of the common four failures and failure treatment method? The following is a small edition of Haipeng machinery manufacturer for you to introduce it in detail. The coupling transmission parts in the use of the process often appear the following 4 kinds of failure: 1, the occurrence of broken teeth, cracks in the outer gear ring. 2. The connecting bolt is broken. 3, contact tooth surface wear. 4, the axial displacement is large, can not mesh.

The causes of the four major failures of the drum gear coupling mainly include the following two aspects:

1. Insufficient oil or lack of oil. Or improper use of oil, resulting in oil calcification, resulting in tooth surface can not be lubricated, or poor lubrication tooth surface wear. Treatment method: As long as the new grease is replaced, the qualified grease oil is injected on schedule to prevent oil leakage, and the oil quantity is sufficient, it can be avoided.

2. The errors of levelness and coaxiality of the two axes are too large. It is higher than the compensation range of the coupling, which makes the shaft teeth and the inner teeth meshing inaccurate, resulting in local contact, and the additional torque. Solution: This kind of fault is difficult to deal with and needs to be stopped. That is, re-alignment, or the reducer focus on new alignment, or focus on the new alignment of the drum. Firstly, find out the part with large deviation error, so as to measure which side the coupling is offset to first, that is, measure the levelness and coaxiality of the spindle and the levelness and coaxiality of the reducer spindle, and then flatten and align according to the mass scale, so as to eliminate the fault.

In addition, for the two axis of the levelness and concentricity error, it will cause drum gear coupling in the rolling process of the phenomenon of stiffness. It is basically similar to the causes of wear of the coupling gear of the lifting accessories mentioned above. In addition to the normal force, the connecting bolt is also subject to additional bending moment, so that it is broken, which is the main reason. The above is for you to introduce everyone about the drum gear coupling common four failures and treatment methods, the relevant content hope to bring you help if you want to know, please continue to pay attention to us.
