There are various types of couplings, mainly including rigid couplings and elastic couplings. Among them, an elastic coupling allows a certain angular deviation or axial deviation during use and has a certain shock-absorbing function. Elastic couplings are further subdivided into shock-absorbing couplings, double shock-absorbing couplings, and other categories. A double shock-absorbing coupling is an optimized design based on a conventional shock-absorbing coupling, with a two-stage shock-absorbing structure, which can more effectively absorb vibration and shock and is suitable for more severe mechanical transmission environments.
