The main body of the REC diaphragm is made of steel, and the diaphragm is made of high-strength stainless steel for springs. The REC diaphragm coupling achieves high torque, high rigidity, and low inertia. REC standard coupling is divided into REC-D-0 type with single diaphragm and REC- □ -T type with double diaphragm. Application: CNC machine tool spindles, servo motors, stepping motors, and occasions where high precision is required for forward and reverse rotation.

1. In the table, the values of rotational inertia and mass are measured when the hole diameter at one side is at its maximum, and the other side at its minimum. 2. In the table, the torsional rigidity is the diaphragm group ’ s theoretical value for torsional rigidity. 3. The maximum rotating speed has taken into consideration the factors such as centrifugal force, rigidity, etc., the dynamic balance is not considered. 4. In the table, the allowable errors in each direction are mutually relevant, they can not reach the maximum value at the same time. Example: the angular error and axial error...
