What aspects should be considered when choosing a coupling type?

The following points can be considered when selecting the coupling type:

According to the size of the load transmitted by the equipment, the speed of the shaft, the installation accuracy of the two parts being connected, etc., refer to the characteristics of various couplings to select a suitable coupling type.

1. The size and nature of the torque to be transmitted and the requirements for the function of buffering and damping.For example, for high-power and heavy-duty transmissions, gear couplings can be selected; for transmissions that require severe impact loads or shaft torsional vibration, tire couplings and other couplings with high elasticity can be selected.

2. The working speed of the coupling and the centrifugal force caused by it.For high-speed transmission shafts, couplings with high balance accuracy, such as diaphragm couplings, should be selected, rather than slider couplings with eccentricity.

3. The magnitude and direction of the relative displacement of the two axes.When it is difficult to keep the two shafts in strict alignment after installation and adjustment, or when the two shafts will have a large additional relative displacement during the working process, a flexible coupling should be used.For example, when the radial displacement is large, you can choose a slider coupling, and when the angular displacement is large or the connection of two intersecting shafts, you can choose a universal coupling.

4. The sex and working environment of the coupling.Comparison of couplings usually made of metal elements that do not require lubrication; couplings that require lubrication are easily affected by the degree of lubrication and may pollute the environment.Couplings containing non-metallic components such as rubber are sensitive to temperature, corrosive media and strong light, and are prone to aging.

5. Due to reasons such as manufacturing, installation, load deformation and temperature changes, it is difficult to maintain strict alignment of the two shafts after installation and adjustment.There is a degree of displacement in the x and Y directions and the deflection angle CI.When the radial displacement is large, you can choose a slider coupling, and when the angular displacement is large or the connection of two intersecting shafts, you can choose a universal coupling.When the two shafts produce a large additional relative displacement during the working process, a flexible coupling should be used.
