The internal and external teeth of the gear coupling will wear and tear the teeth due to long-term use, which will affect the service life of the coupling. The reason for the matching of the teeth is that the coupling itself has no hardness and the gear surface has not been tempered. The service life of the coupling is not too high due to dipping in fire. Another reason is that the axial deviation and displacement of the coupling installation increase, which leads to the incomplete matching of the internal and external teeth of the coupling. After long-term use at high speed and high torque, This phenomenon occurs.

The vibration damping performance of the gear coupling can be absorbed by the energy in the rigid components, thereby removing and reducing the mutual impact force of the teeth during vibration, and improving the service life of the entire coupling.

The gear coupling has a small radial standard and a large load. It is often used in shaft transmissions that are not considered heavy-duty conditions. A gear coupling with good precision and dynamic balance can be used for transmission, such as the shaft transmission of a dyeing steam turbine.

Punching phenomenon and processing method of gear coupling:

The horizontality and coaxiality of the two shafts are too large, which exceeds the compensation plan of the coupling, so that the meshing of the shaft teeth and the internal teeth is not correct, and the formation is somewhat out of contact, and an additional torque appears, and this additional torque can be decomposed It is an axial force acting on the inner ring gear. The magnitude of this force depends on the size of the fault and is proportional to the fault. The greater the fault, the greater the force, which will cause the axial displacement of the inner ring gear of the lifting accessories coupling. If If the displacement is too large, it will be uncontrollable, resulting in serious wear of the gears, or even broken teeth. The inner and outer teeth cannot be meshed until the transmission cannot be carried out. It is difficult to deal with this defect and needs to be shut down.

Summarize:

The gear coupling has the function of compensating the relative displacement of the two shafts. The gear coupling is composed of main parts such as the inner ring gear, the gear sleeve and the end cover. The entire operation process of the gear coupling is relatively simple, the equipment is highly automated, and less labor is required. Manual feeding or automatic feeding by conveyors can be used.
