Coupling information:

The coupling is installed between the driving side and the passive side of the power transmission, and plays the role of transmitting rotational torque, compensating for installation deviation between shafts, absorbing equipment vibration and buffering load impact. One of the functions of the coupling is to absorb and compensate for shaft-to-shaft misalignment through its own deformation. The greater the flexibility, the stronger the ability to absorb deviation; the smaller the flexibility, the weaker the ability to absorb deviation. Generally speaking, the deviation between the shaft and the shaft is divided into the following three aspects: the connection between the coupling and the peripheral equipment is realized by inserting the shaft of the equipment into the shaft hole of the coupling. The shaft hole forms of the coupling generally include keyway type, clamping type, clamping + keyway, top wire type, expansion type, etc. The keyway type is the most widely used, suitable for ordinary motors, ordinary reducers and ordinary transmission shafts. The clamping type is used in servo motors, stepper motors, and various synchronous transmission shafts. The shaft and the hole are closely matched without any transmission gap. If an additional keyway structure is added, the torque transmission capacity can be enhanced. The top screw type is suitable for small shaft diameter and small torque transmission occasions, such as micro motors, encoders, etc.
