Diaphragm forms are divided into: continuous polygonal ring shape, circular ring shape, separate connecting rod shape, spoke shape, formed diaphragm, and waved diaphragm.
The characteristics of continuous polygonal ring and circular ring: Each coupling is composed of several diaphragms of equal thickness. The outer edge of each piece is arc-shaped, which has better elasticity, simple shape and convenient processing, but the elasticity is poor. The elasticity with a small number is better than the elasticity with a large number of sides, but if the number of sides is too small, the stability will also be reduced when running in one direction, only half of the ring side bears the transmission torque.
Separate connecting rod shape features: Each diaphragm is composed of a separate thin rod to form a polygon. The rod has a simple shape and is convenient to manufacture, but requires precise hole spacing. Its performance is basically the same as that of a continuous polygonal ring, but its strength and speed are lower. , Suitable for occasions where the coupling size is restricted.
The characteristics of the spoke shape: Each coupling is composed of several pieces. The screw holes on the outer edge and the inner edge are respectively connected with the driving and driven half couplings, which are twisted during operation. The forming holes on the diaphragm are for increasing Elasticity, because elasticity requires that the difference between the inner and outer diameters should not be too small, it is generally appropriate to transmit medium and small power.
The characteristics of the formed diaphragm: Each coupling is composed of a single diaphragm. The thickness of the diaphragm decreases regularly from the inner radial to the outer hyperbola to maintain the same strength condition. Its material utilization rate is high and the integrity is good. It is especially suitable for High-speed transmission, but the manufacturing precision of the diaphragm is high.
The characteristics of the corrugated diaphragm: The diaphragm is corrugated in the axial section, with high elasticity and good compensation performance.The monolithic hyperbolic type with the same thickness and unequal thickness of the diaphragm has better performance, and is currently used in many applications.
