Introduction:

It turns out that anyone who uses a diaphragm coupling knows that the diaphragm assembly is one of the more easily worn parts. Because the service life of the diaphragm assembly directly determines the service life and working efficiency of the coupling. Diaphragm couplings produced in various regions have a large gap with foreign products in appearance quality and service life. For this reason, researchers have carried out research on diaphragm coupling], but some of the results are only theoretical research results, without a good solution to the structure of the diaphragm component, and some of the results only discuss a special structure of the diaphragm, or only analyze the single diaphragm, so the conclusions are not universal.

Innovative design principles for diaphragm couplings:

In fact, all of this is because when there is some angular displacement or axial displacement between the power machine and some other working machine, we find that the diaphragm group in the diaphragm coupling that connects the power machine to the working machine creates additional stresses. When the diaphragm coupling is in the state of high speed operation or repeated positive and negative rotation, the diaphragm group is subjected to the action of alternating stress, which is more prone to fatigue failure. In order to analyze the damage causes of the diaphragm group and extend the service life of the coupling transmission, taking the waist diaphragm as an example, the structure of the diaphragm group was determined based on TRIZ theory, and then CosmosWorks was used to analyze the strength of the diaphragm group, and the traditional diaphragm group and the diaphragms with patches were analyzed and compared.

To sum up:

Mechanical manufacturers in order to solve some of the more common diaphragm group easy to wear and destroy the problem, these are from some TRIZ theory to design the diaphragm coupling with the patch, using some other software to analyze the diaphragm group of traditional coupling and the diaphragm group with the patch coupling. The results show that the high stress region appears near the hinge point on the diaphragm, and the low coefficient region also appears near the hinge point, which indicates that the failure is easy to occur in this region. Under the same working condition, the high stress region and low coefficient region of the diaphragm group can be reduced, so as to improve the service ability of the diaphragm group.
