Flexible Couplings

Steel Laminae 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. Diaphragm 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 plum blossom coupling is composed of two semi-couplings with convex claws and a plum-shaped flexible non-metallic element whose hardness can be adjusted. By embedding the plum-shaped flexible element into the two semi-couplings to realize the connection, plum coupling has the characteristics of compensating the relative displacement of the two axes, reducing vibration and buffering, simple structure and easy maintenance without lubrication.

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 pin bush 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.

The tyre coupling adopts tyre body-shaped rubber elements, which are connected with two semi-couplings through bolts to realize torque transmission and displacement compensation. Tyre coupling has high elastic performance, small torsional rigidity, strong damping capacity, large axial compensation capacity, and good damping performance.

The drum coupling is an important part in the transmission system of crane equipment. It connects the power input shaft of the reducer with the drum, transmits torque and restricts the axial movement of the drum at the same time. It also has mechanical or electronic wear alarm, and is one of the core parts of the drum crane mechanism.
