Products Features

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.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.

GH Oldham type coupling cross sliding set screw coupling.

>The colloid material is imported PA66, which has good wear resistance, corrosion resistance and electrical insulation;
>Sliding design can compensate radial and angular deviation more effectively;
>Detachable design, easy to install;
>Fastening method of clamping screw.

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.
