The role and characteristics of diaphragm in the structure of diaphragm coupling

Separate connecting rod shape characteristics: each diaphragm is composed of a single thin rod to form a polygon, the rod shape is simple, easy to manufacture, but the hole distance is required, its working performance is basically the same as the continuous multilateral ring, but the strength and speed are lower, suitable for the diaphragm coupling size is limited occasions.

Spok-shaped characteristics: each coupling is composed of a number of pieces, the outer edge and the inner edge of the screw holes are connected with the main and slave half coupling, torsion occurs when working, the forming hole on the diaphragm is to increase the elasticity, because the difference between the inner and outer diameters should not be too small, generally to transfer small power is appropriate.

The characteristics of the molded diaphragm: each coupling is composed of a single diaphragm, the thickness of the diaphragm is reduced from the inner radial to the outer hyperbolic rule to maintain the equal strength conditions, the material utilization rate is high, the integrity is good, especially suitable for high-speed transmission, but the manufacturing accuracy of the diaphragm is high.

The characteristics of the corrugated diaphragm: the diaphragm is waveform in the axial section, high elasticity and good compensation performance. The monolithic hyperbolic type with equal thickness and unequal thickness of diaphragm has better performance and is widely used at present.
