What are the characteristics of the structure of the diaphragm coupling?

　　Diaphragm coupling structure: 4 holes 6 holes 8 holes 10 holes 12 holes.

　　1. Diaphragm mode: consecutive polygonal ring, circular ring, separate connecting rod shape, spoke shape, formed diaphragm, wave diaphragm.

　　2. Features of successive 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, convenient processing, but poor elasticity. In addition, the elasticity with a small number of sides is better than the elasticity with a large number of sides, but if the number of sides is too small, the stability will also decrease. In one-way operation, only half of the ring side bears the transfer torque.

　　3. Features of separate connecting rod shape: Each diaphragm is composed of a single thin rod to form a polygon. The rod has a simple shape and is convenient to manufacture. However, the hole distance is required. The operation function is basically the same as that of the continuous polygon ring, but the strength and speed are relatively higher. Low, suitable for occasions where the size of the coupling is restricted.

　　4. The characteristics of the spoke shape: Each coupling is composed of several pieces. The screw holes on the outer and inner edges are separated and connected with the driving and driven half couplings. Changes occur during operation. The formed holes on the diaphragm are In order to add flexibility, the difference between the inner and outer diameters of the elastic demand should not be too small, and it is generally appropriate to transmit medium and small power.

　　5. The characteristics of the formed diaphragm: Each coupling is composed of a single diaphragm. The thickness of the diaphragm is regularly reduced from the inner to the outer hyperbola to maintain equal strength conditions. The material utilization rate is high, and the overall performance is good. It is suitable for high-speed transmission, but the production precision of the diaphragm is higher.

　　6. The characteristics of the wavy diaphragm: The diaphragm is wavy in the axial section, with high elasticity and good compensation function.The single-piece hyperbolic type with equal thickness and unequal thickness of the diaphragm has better functions, and is now used more frequently.
