Most commonly used couplings have been standardized or normalized
Posted by Admin | 04 Nov
Coupling is also called coupling. A mechanical component used to firmly connect the driving shaft and driven shaft in different mechanisms to rotate together and transmit motion and torque. Sometimes it is also used to connect the shaft with other parts (such as gears, pulleys, etc.). It is usually composed of two halves, which are respectively connected with keys or tight fits, fastened on the two shaft ends, and then connected by some way.
The coupling can also compensate the offset (including axial offset, radial offset, angular offset or comprehensive offset) between two shafts due to inaccurate manufacturing and installation, deformation or thermal expansion during operation
The coupling shall have the following properties:
(1) The movability of the coupling refers to the ability to compensate the relative displacement of the two rotating components.
(2) Buffering. For the occasion of starting with constant load or changing working load, the coupling shall be equipped with elastic elements for buffering and vibration reduction to protect the prime mover and working machine from less or no damage.
(3) Safe and reliable, with sufficient strength and service life.
(4) Simple structure, easy assembly, disassembly and maintenance.
