DM Diaphragm coupling
DM Diaphragm coupling
Series DM disc coupling adopts advanced aviation and space fight technique in the world for production. The diaphragm adopts vacuum smelted ultrastrength alloy steel and electronic beam welding new technology for manufacture. It makes the coupling to have advantages like larger transmission power, lightweight, big flexibility, superior various mechanic properties, etc while it has the same outside diameter. The flexible body and the flange are reaming hole close fit. The good dynamic balancing performance, easy to mount and dismount, greater safety coefficient and long service life make the metallic flexible coupling to reach a perfect degree. It can be widely used for important unit with big torque and high speed.
