DMB series aluminum alloy high rigidity double disc with single step keyway and eight screws coupling

 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 characteristics are exactly the same.

 6.The diaphragm structure has strong ability to compensate radial,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.
