Classification of Disc Membrane Couplings

Rokee^® is a well-known high-quality disc membrane coupling supplier from china, learn more about classification of disc membrane couplings, pls contact Rokee technology. Rokee has been established in China since 1999, over the years, with excellent quality, we have been continuously providing many disc membrane coupling products of various categories and uses complying with multiple standards and a full range of services, from the disc membrane coupling selection to final installation and operation, for the industry fields of ferrous metallurgy, nuclear power, gas turbine, wind power, ropeway construction, lifting transportation, general equipment, etc.

The disc membrane coupling is a kind of high-performance metal flexible coupling, which compensates axial and angular displacements by the deformation of elastic diaphragm while transferring torque, disc membrane coupling features with compact structure, large transmission torque, long service life, maintenance-free, high temperature resistance, acid and alkali resistance, and corrosion resistance, suitable for shafting transmission in high temperature, high speed and corrosive environment.

The disc membrane coupling utilize a single or a series of plates or diaphragms for the flexible members, disc membrane coupling transmits torque from the outside diameter of a flexible plate to the inside diameter, across the spool or spacer piece, and then from inside to outside diameter. The deflection of the outer diameter relative to the inner diameter is what occurs when the diaphragm is subject to misalignment.
