Plum coupling, diaphragm coupling which is more suitable for servo motor

Plum coupling, diaphragm coupling which is more suitable for servo motor? Both couplings can be selected for the servo motor, then which of the two couplings is more suitable for the servo motor?

Servo motor coupling selection is generally based on the material of its elastic components, the plum coupling is widely used in the spindle servo motor, but the diaphragm coupling is used in the transmission servo motor, such as: CNC lathes and CNC milling machines, the X axis and Y axis of the CNC milling machine belong to the drive servo motor, and often do positive and negative rotation in the work, then the diaphragm coupling is better than the plum coupling. CNC lathe spindle servo motor, the choice of a plum coupling can be, because the plum coupling and diaphragm coupling compared with the price advantage, and the size of the same, the plum coupling revolution limit is smaller than the diaphragm coupling, the plum coupling elastomer also has a damping effect, the allowable axial deviation is larger than the diaphragm coupling, and the greater the deviation. The faster the elastomer of the coupling is worn.

In the actual situation, the choice of which coupling needs to be considered by comprehensive factors, and flexible application.
