What kind of motor coupling is commonly used for diaphragm couplings

Diaphragm coupling, It is a flexible coupling, with high torque rigidity and high sensitivity, zero backlash, clockwise and counterclockwise rotation characteristics are exactly the same, stainless steel diaphragm compensates for radial, angular and axial deviations, diaphragm coupling Often used in servo motors.
   1. The characteristic of diaphragm coupling is a bit like a bellows coupling. In fact, the way the coupling Transmission torque is similar.The diaphragm itself is very thin, so it is easy to bend when the relative displacement load is generated, so it can withstand up to 1.5 degrees of deviation, while generating a lower bearing load in the servo system.
   2. The diaphragm coupling is composed of at least one diaphragm and two shaft sleeves.The diaphragm is fastened to the shaft sleeve with a pin and generally does not loosen or cause backlash between the diaphragm and the shaft sleeve.Some manufacturers provide two diaphragms, and others provide three diaphragms, with one or two rigid elements in the middle, and the two sides are connected to the shaft sleeve.　　
    3. Diaphragm couplings are often used in servo systems. Diaphragms have good torque rigidity, but are slightly inferior to bellows couplings.
    4. On the other hand, the diaphragm coupling is very delicate, and it is easy to be damaged if it is misused or not installed correctly during use.Therefore, it is very necessary to ensure that the deviation is within the tolerance range of the normal operation of the coupling.
    5. Adjust the model according to the shaft diameter: the initially selected coupling size of the bearing coupling, that is, the shaft hole diameter d and the shaft hole length L, should meet the requirements of the main and driven end shaft diameters, otherwise they must be adjusted according to the shaft diameter d The specifications of the coupling.
