Products Features
Diaphragm coupling is suitable for shafting transmission in high temperature, high speed and corrosive medium working conditions, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery , chemical machinery, mining machinery, metallurgical machinery, aviation (helicopter), naval high-speed power transmission system, steam turbine, piston power mechanical transmission system, crawler vehicles, and generator set high-speed, high-power mechanical transmission system, through dynamic balance Later applied to high-speed transmission shafting has become more common.
Compared with the gear coupling, the diaphragm coupling has no relative sliding, does not need lubrication, sealing, no noise, basically does not need maintenance, is easy to manufacture, and can partially replace the gear coupling. Diaphragm couplings have been widely used in industrialized countries in the world. In my country, machinery industry standards have been formulated and revised to new industry standards: JB/T 9147-1999 (replacing ZB/T J19022-90) Couplings relationship between torques.
>High torque rigidity, can accurately control the rotation of the shaft, can carry out high-precision control
>The lengthening design can compensate the radial, angular and axial deviation more effectively
>Designed for servo and stepping motor
>No gap between the shaft and sleeve connection, general for positive and negative rotation
>Low inertia, suitable for high speed operation
>The diaphragm is made of spring steel with excellent fatigue resistance
>Fastening method of clamping screw
