What are the causes of tooth coupling?

In the use of the gear coupling sometimes there will be a phenomenon of eating, once this phenomenon has a very large impact on our use, so we must understand the reasons for this phenomenon are what can better solve this problem.

What are the causes of tooth coupling?

1, the internal and external teeth of the gear coupling due to long-term use will lead to tooth wear will appear tooth phenomenon, thus affecting the service life of the coupling, the tooth matching reason is that the coupling itself has no hardness, the gear surface is not conditioned 蘸火, resulting in reduced service life of the coupling.

2, another reason is that the coupling installation axial deviation displacement increases, resulting in the coupling internal and external teeth are not completely matched, after high speed and high torque long-term use will appear this phenomenon. The radius of curvature of the drum curve is proportional to the thinning amount of the inner teeth, that is, it is related to the meshing clearance of the teeth, which causes the phenomenon of the inner and outer teeth to beat, affecting the service life of the coupling.

3, the gear coupling in the transmission may also occur bolt break, appear tooth phenomenon; If such a phenomenon occurs, the coupling should be removed immediately for analysis and inspection, and to carry out regular maintenance and inspection of the coupling, it is also necessary to replace the bolts, so as to increase the service life of the coupling.
