DMB 3D print shaft coupling aluminum alloy jaw shaft flexible 8 screws step double diaphgrams coupler shaft CNC

 1.The main part is made of #45 steel with keyway.

 2.The diaphragm is made of 304 stainless steel.

 3.The diaphragm is multilateral arc shape with eight screw,in order to improve the precision and torque.

 4.This structure is good for anti-vibration ,safty and a longer service life.

 5.No clearance ,clockwise and counterclockwise rotation charcteristics are exactly the same.

 6.The diaphragm structure has strong ability to compensate rodial ,angular and axial  deviations.

 7.This structure will transmit larger torque and lower transmission inertia.

 8.This series coupling is commonly used in servo motor and stepper motor.

 9.High rigidity ,high sensitivity.
