couplingWhat is the role in the air compressor？How does it work？What do we need to pay attention to when choosing a coupling？Today Xiaobian has sorted out the following content on these issues:

First, the working principle of the coupling

Couplings, also known as couplings, are used to firmly connect the drive shaft and driven shaft in different mechanisms to rotate together and transmit movement and torque。Sometimes also used to connect shafts to other parts (such as gears, pulley, etc.)。It is often composed of two halves, respectively connected by a key or a tight fit, fastened at the end of the two axes, and then the two halves are connected in some way。The coupling can compensate the offset (including axial deviation, radial deviation, angular deviation or comprehensive deviation) between the two axes due to inaccurate manufacturing installation, deformation or thermal expansion during operation;As well as cushioning shock and absorbing vibration。

Second, the role of the coupling

Coupling refers to a device that connects two shafts or shafts and rotating parts, rotating together in the process of transmitting movement and power, and does not come off under normal circumstances。Sometimes it is also used as a safety device to prevent the connected parts from bearing excessive loads and play the role of overload protection。

Three, coupling performance requirements

1, safe, reliable, with enough strength and service life。

2, simple structure, installation and disassembly, easy maintenance。

3, mobility, the mobility of the coupling refers to the ability to compensate the relative displacement of two rotating components。Factors such as manufacturing and installation errors between connected components, temperature changes during operation and deformation under load all require portability。Portability compensates for or relieves additional loads between shafts, bearings, couplings and other components due to relative displacement between rotating members。

4, cushioning, for regular load starting or working load changes, the coupling needs to have cushioning and reducing elastic elements to protect the prime mover and the working machine from less or no damage。
