Analyze why the lower coupling should be concentric

Shafting transmission usually connects the main and driven shafts by one or several couplings to form a shafting transmission system to transmit rotation or motion. It is mainly due to the shaft connection of the motor, reducer and working machine. The shaft hole form, connection form and size mainly depend on the type and size of the connected shaft. In product design, the shaft is generally designed according to the cylindrical and conical shaft depth standards. , the shaft depth standard is designed for the shaft.

The coupling is a component that connects two shafts axially and transmits torque and motion, and has the ability to compensate for the offset of the two shafts. On this basis, the coupling should be concentric. From a mechanical point of view, the coupling is subjected to force. It will affect the motor, etc.

In the mechanical transmission, the coupling is to reduce the vibration of the mechanical transmission system and reduce the impact load. It should also have the function of buffering and shock absorption, and sometimes it also has the function of overload safety protection. If the coupling is concentric, the motor power consumption is normal and the transmission efficiency is high. It will be very high; if the power loss increases when the coupling is not concentric, the transmission efficiency will decrease, and the current of the motor will increase, which will cause the motor to be burned out.
