The selection of couplings mainly requires us to consider the required transmission shaft speed, load size, installation accuracy of the two connected components, rotation stability, and price, and refer to the characteristics of various types of couplings to choose the suitable coupling type for use. Let's take a look at the introduction of Snake Spring Coupling Company Shanghai Maidong.

Many couplings are basically standardized or normalized. The task of a designer is to make choices, not to design. The basic steps for choosing to use a coupling are as follows:

1、 The magnitude and nature of the torque to be transmitted, as well as the requirements for buffering and damping functions

For example, for high-power heavy-duty transmissions, we can choose to use gear couplings; For severe impact loads or vibration transmissions that require elimination of shaft torsion, we can choose to use high elasticity couplings such as tire type couplings.

2、 The working speed of the coupling and the magnitude of the centrifugal force caused by it

For high-speed transmission shafts, couplings with high balance accuracy, such as diaphragm couplings, should be selected instead of eccentric slider couplings.

3、 The magnitude and direction of the relative displacement between the two axes

When it is difficult to maintain strict and precise alignment of the two shafts after installation and adjustment, or when there will be significant additional relative displacement between the two shafts during operation, a flexible coupling should be selected. For example, when the radial displacement is large, a sliding block coupling can be selected, and for connections with large angular displacement or intersecting axes, a universal joint can be used.

4、 Reliability and working environment of couplings

It is often made of metal components and does not require lubrication, making the coupling more reliable; The performance of a lubricated coupling is easily affected by the degree of lubrication and is likely to cause environmental pollution. Couplings with non-metallic components such as rubber are sensitive to temperature, corrosive media, and strong light, and are prone to aging.
