What are the considerations for selecting couplings?

- Dec 08, 2017 -

The choice of the main coupling shaft coupling speed to consider the level of transmission, the size of the load is connected to the two components of the installation accuracy, the stability of the rotation, the price, etc., refer to the characteristics of various types of couplings, choose a suitable Coupling type.

Specific choices can consider the following points:

1, the size and nature of the torque to be transmitted, and the requirements for cushioning damping. For example, for high-power heavy-duty transmission, tooth couplings are optional; for highly shock-absorbing loads or transmissions that require the elimination of torsional vibration of the shaft system, couplings with high flexibility such as tire type couplings may be used. The company is located in:

2, the working speed of the coupling and the centrifugal force caused by the size. For high-speed transmission shaft, the balance should be used for high precision couplings, such as diaphragm coupling, etc., but should not be used eccentric coupling exists. The company is located in:

3, the relative displacement of the two axes the size and direction. When the installation and adjustment, it is difficult to maintain strict precise alignment of the two axes, or two axis during work will have a greater additional relative displacement, the choice should be flexible coupling. For example, when the radial displacement is larger, the optional slider coupling, angular displacement larger or intersect the two axes can choose to use universal coupling and so on. The company is located in:

4, the reliability of the coupling and working environment. Non-lubricated couplings, usually made of metal, are more reliable; lubricated couplings are susceptible to lubricity and may pollute the environment. Couplings containing non-metallic elements such as rubber are sensitive to temperature, corrosive media and glare, and are prone to aging. The company is located in:

5, coupling manufacturing, installation, maintenance and cost. In meeting the premise of use performance, should be easy to install and disassemble, simple maintenance, low cost coupling. For example, the rigid coupling is not only simple in structure, but also easy to assemble and disassemble, and can be used for a transmission shaft with low speed and rigidity. General non-metallic elastic element coupling (such as elastic sleeve pin coupling, elastic pin coupling, plum-shaped elastic coupling, etc.), due to its good comprehensive ability, widely used in general, small Power transmission.
