Gear coupling as transmission device of equipment

The vibration damping performance of the gear coupling can be achieved by absorbing energy from rigid components, 

thereby eliminating and reducing the mutual impact force of the teeth during vibration, and increasing the service life of 

the entire gear coupling. The use of gear couplings is more reasonable in transmission devices where operation unevenness 

is serious and assembly is inaccurate but rarely overloaded. This phenomenon will occur after long-term use of high speed 

and high torque. The vibration damping performance of gear couplings can be achieved by absorbing energy from rigid 

components, thereby eliminating and reducing the mutual impact force of the teeth during vibration. The reason for the 

tooth matching is that the coupling itself has no hardness.

Heating to the specified temperature in the heating furnace and detecting the temperature of the workpiece. We took out 

the coupling, turned it over, and put it in the furnace to continue heating. Such as using firewood to heat a large coupling. 

After two or three hours, use the measuring rod to repeatedly measure the hole diameter until the measuring rod can freely 

enter the coupling hole, and the heating is complete. Lift out the coupling and install the strike plate, lift or other set of tools. 

The gear coupling has an oil hole drilled at the bottom of the outer gear tooth groove that communicates with the oil 

collection groove. Using the centrifugal force generated by the high-speed operation of the gear coupling, the gear surface 

is not tempered and dipped in fire, resulting in a reduction in the service life of the coupling.

We spray oil into the meshing area of the internal and external teeth to fully lubricate them. The vibration performance of the 

gear coupling can be absorbed by the rigid components, thereby eliminating and reducing the mutual impact force of the 

teeth during vibration, and improving the service life of the entire coupling. When overloaded, the safety pin is cut off and the 

torque transmission stops. At this time, the pressure of the external teeth and the internal teeth causes axial movement, 

thereby pressing the switch to cut off the motor. Long-term use of the internal and external teeth of the gear coupling 

will cause tooth wear and tooth beating, which will affect the service life and increase the installation axial deviation and 

displacement.
