Diaphragm 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. It 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.

Rokee’s RL series Steel Laminae Couplings are independently developed on the basis of high-quality products from Europe and Japan. It has smaller volume, larger torque of the same type, more reasonable proportioning size, large compensation range, light weight and small moment of inertia. Special elastic gasket design is adopted in the hole connection part of bolt and diaphragm group, which greatly reduces the stress concentration in the hole edge part, eliminates the tear loss of diaphragm, and extends the service life. With modular design, the coupling assembly is simple and its maintenance and replacement are quick. The performance far exceeds the national standard JM series products, which are widely used in fan systems, steam turbine units and other important industrial fields.

The pin and bush couplings accept parallel, angular and axial misalignment and can provide considerable torsional flexibility. The flexible pin gear coupling is designed with non-metallic flexible pin, two toothed semi-couplings and a toothed sleeve ring with an outer ring. It uses non-metallic flexible deformation to transfer torque and cushion shock and compensate angular displacement.

The flexible pin coupling is a basic transmission parts that has simple structure, needs no lubrication, and is easy to manufacture, install and disassemble the flexible pin. It uses two semi-couplings with flange holes and a non-metallic flexible pin for crane to transmit torque, suitable for low-to-medium speed and low-to-medium torque occasions.

The design of the elastic sleeve pin coupling is simple and clever in design and has wide applicability. It uses the pin with elastic sleeve to connect two semi-couplings with pin holes to realize torque transmission and larger angular compensation. At the same time, it has good shock absorption and buffering performance, which can be used in high-speed occasions without lubrication and requiring easy pin sleeve replacement.
