Description
Two diaphragms coupling bore 4mm to 8mm, length 27mm, width 19mm. For occasions where the load is frequently started or the working load changes, the coupling acts as a buffer for protection.

Tips: Structure of diaphragm coupling
Diaphragm coupling is a metal flexible coupling, which is a transmission device that uses a metal elastic diaphragm as a flexible element to transmit torque. Its main features: large torque transmission capacity, diaphragm deformation to absorb the misalignment of the unit, no relative movement between the parts, no wear, no noise, long vibration damping life, and no need for lubrication. The torsional stiffness and critical speed can be adjusted by changing the outer diameter or wall thickness of the intermediate section, thereby improving the torsional vibration characteristics of the unit.
The diaphragm coupling is composed of at least one diaphragm and two shaft sleeves. The diaphragm is fastened to the sleeve with a pin and generally will not loosen or cause backlash between the diaphragm and the sleeve. Some manufacturers provide two diaphragms, and some provide three diaphragms, with one or two rigid elements in the middle, and the two sides are connected to the shaft sleeve. The difference between the single diaphragm coupling and the double diaphragm coupling is the ability to handle various deviations. In view of the complex bending of the diaphragm, the single diaphragm coupling is not suitable for eccentricity. The double diaphragm coupling can bend in different directions at the same time to compensate for eccentricity.
