Coupling Life Affecting Factors and Service Life Extension

Release Time:

Apr 13,2023

Generally, the working life of the couplings produced by our company is about 2 years, and it may vary depending on the application environment, but usually the error is not large. The elastic coupling is obviously under tension because of its elasticity. The lifespan of general elastomers is years. Because the elasticity has the effect of alleviating friction and reducing vibration, it is often used in places with strong vibration.

Generally, the working life of the couplings produced by our company is about 2 years, and it may vary depending on the application environment, but usually the error is not large. The elastic coupling is obviously under tension because of its elasticity. The lifespan of general elastomers is years. Because the elasticity has the effect of alleviating friction and reducing vibration, it is often used in places with strong vibration.

There are many factors that affect the service life of the coupling, such as the selection of coupling materials, heat treatment process, manufacturing accuracy, assembly and installation accuracy of the coupling, use and maintenance status, etc., so how to maintain the coupling to extend its life:

1. Before installation, the end faces of the two shafts should be cleaned, and the matching conditions such as the key grooves on the end faces should be checked;

2. After the coupling is installed, it is necessary to check all the screws for one shift in normal operation. If it is found to be loose, it must be tightened. Repeat this for several shifts to ensure that it will not loosen;

3. In order to prevent the fretting wear of the diaphragm during high-speed operation, resulting in micro-cracks and damage to the diaphragm bolt holes, solid lubricants such as molybdenum disulfide can be applied between the diaphragms or anti-friction coatings can be applied to the diaphragm surface. layer processing;

4. The coupling should prevent long-term overloading and operation accidents;

5. During the operation of the coupling, you should always check whether there is any abnormality in the coupling. If there is any abnormality, it must be repaired in time; therefore, in order to prolong the service life of the coupling, it is necessary to maintain the coupling frequently. Axis device. Well, the above is the detailed information on the factors affecting the life of the coupling and the extension of its service life.
