The reasons for the rapid wear of the gear of the crane gear coupling are as follows:
1) Poor installation accuracy, large offset of the two shafts, improper meshing of the internal and external teeth, and large local contact stress.
2) Poor lubrication. Since it is a connection form without relative motion, the grease cannot be automatically replenished after being squeezed out, so it may be in a dry friction state to transmit torque, thereby accelerating the wear and damage of the tooth surface.
3) Working in a high temperature environment, the lubricating oil is dried, which deteriorates the lubrication state and accelerates the wear and damage of the tooth surface.
4) Violating operating procedures, frequently braking in reverse, and accelerating the damage of the gear teeth.
The key measures to increase the service life of the gear coupling are:
Improve the installation accuracy of each component, strengthen daily inspection and regular lubrication, and at the same time comply with operating procedures to improve operating techniques.
