Ductile Iron Universal Stepped Coupling

Couplings, also known as couplings. A mechanical component used to firmly connect the active and driven shafts in different mechanisms and rotate them together, transmitting motion and torque. Sometimes it is also used to connect a shaft with other parts (such as gears, pulleys, etc.). It is often composed of two halves, which are connected by keys or tight fits, fastened at the ends of the two shafts, and then connected together in some way. Couplings can also compensate for the displacement (including axial displacement, radial displacement, angular displacement, or comprehensive displacement) between two shafts due to inaccurate manufacturing and installation, deformation during operation, or thermal expansion; And mitigate impact and absorb vibration.
