High-speed diaphragm coupling manufacturers to introduce you to the coupling how to choose:

1. Because of production, installation, load deformation and temperature change, when installed and adjusted, it is impossible to maintain the harsh alignment of the two axes.

There is a certain level of X, Y azimuth offset and tilt Angle CI. When the axial deviation is large, the guide slide coupling can be selected, the angular speed is large or the connection between two axes can be selected. When the two axes form a large additional relative displacement during the whole process of work, a flexible coupling should be used.

2. The working speed ratio of the coupling and the formation of centripetal force scale.

For the high-speed rotating shaft, a balanced and high-precision coupling should be used, such as a pulse damper coupling, etc., rather than a guide slide coupling with axial force.

3. Specification of the scale and characteristics of the rotation to be transmitted and its effect on buffer shock absorption.

For example, for the light-load transmission system with large power, the gear coupling can be selected; For more severe impact loads or the transmission system requiring the removal of shafting distortion sensation, couplings with high elasticity such as crawler couplings can be selected.

4. The working speed ratio of the coupling and the formation of centripetal force scale.

For the high-speed rotating shaft, a balanced and high-precision coupling should be used, such as a pulse damper coupling, etc., rather than a guide slide coupling with axial force.

5. Scale and orientation of the relative displacement of the two axes.

When, after installation and adjustment, it is impossible to keep the two axes harsh alignment, or the two axes will form a large additional relative displacement during the whole process of work, a flexible coupling should be used. For example, when the axial deviation is large, the guide slide coupling can be selected, and the coupling can be selected for the connection of the angular speed is large or the connection of the two axes.

6. The reliability and working environment of the coupling.

Generally, the coupling made of metal materials and components that do not need to be moistened is more reliable, and the coupling that needs to be moistened is vulnerable to the harm of the sound level of moistening, and it is likely to be environmental pollution. Couplings with non-metallic components such as vulcanized rubber are more sensitive to temperature, corrosive substances and strong light, and are very easy to embrittlement.
