Series PM diaphragm coupling is designed and manufactured through referring and digesting Danish technique. It is formed through sheet riveting or through bolt connection. The sheet increases the flexibility through pre-stress treatment or pre-deformation treatment. There are boltholes on inner and outer edge circumference. Use bolts to connect the drive flange and driven flange respectively.
The transfer torque range of this coupling is wide, the max value can reach 4,000,000 Nm, the transfer power distance is long, and the max length can reach 15 m without intermediate support. The intermediate adopts these advantages like thin wall tubing for processing, having light weight, no deformation, good rotary performance, absorbing vibration and reducing impact, etc. When it is used at a great load fluctuation condition, the effect is better. It is suitable for large revolving kiln, cooling tower, fan, rolling mill, etc.
