Couplings
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.

Detail
When choosing a coupling type, the following items should be considered.
① The size and nature of the required transmission torque, the requirements for buffering and vibration reduction functions, and whether resonance is possible.
The relative displacement of the two axes is caused by manufacturing and assembly errors, shaft loading and thermal expansion deformation, and relative motion between components.
(3) Allowable dimensions and installation methods, in order to facilitate assembly, adjustment and maintenance of the necessary operating space. For large couplings, it should be possible to achieve disassembly without axial movement of the shaft.
In addition, the working environment, service life, lubrication, sealing and economic conditions should also be considered, and then refer to the characteristics of various types of couplings to select a suitable coupling type.
