Diaphragm coupling has obvious shock absorption effect, no noise, no wear and tear, long service life, adapts to high temperature (-80+300) and harsh environment, and operates under impact and vibration, with high transmission efficiency up to 99.86%. Especially suitable for medium and high speed high power transmission, simple structure, light weight, small size, easy assembly and disassembly. It can be assembled and disassembled without moving the machine. It does not need lubrication. It can accurately transfer the rotational speed without slip and has fast rotation.

Elastic coupling has good performance of compensating axial, radial and angular axis offset, better vibration reduction performance, simple structure, stable and reliable operation, no noise, no lubrication, simple maintenance, easy handling, good workmanship, low cost, can be derived into a variety of structural forms, good versatility, applicable model. It is widely used and popularized. One of the most prominent advantages of the coupling is that it only needs to be suitable for the difficult installation of axis alignment and to minimize the working conditions of auxiliary working hours.
