What are the structure of the diaphragm coupling and their advantages

膜片联轴器结构形式：一般分为4孔、6孔、8孔、10孔、12孔等，如需其他孔数可订制。

   1,Diaphragm couplingDiaphragm forms: continuous polygonal ring shape, circular ring shape, separate connecting rod shape, spoke shape, formed diaphragm, waved diaphragm.

   2. FlexibilityDiaphragm couplingFeatures of continuous polygonal ring and circular ring: each diaphragmCouplingIt is composed of several diaphragms of equal thickness. The outer edge of each film is arc-shaped. The elasticity is better, and the shape is simple, and the processing is convenient, but the elasticity is poor. In addition, the elasticity of fewer sides is better than the elasticity of more sides. If the number is too small, the stability will be reduced when running in one direction, only half of the ring side bears the transfer torque.

   3. DiaphragmCouplingSeparate connecting rod shape feature: each diaphragm is composed of a separate thin rod to form a polygon. The rod has a simple shape and is convenient to manufacture. Its working performance is basically the same as that of a continuous polygonal ring, but its strength and speed are lower, which is suitable for diaphragm coupling The size of the device is restricted.

   4. The characteristics of the spoke shape of the diaphragm coupling: each diaphragm coupling is composed of several pieces, and the screw holes on the outer and inner edges are respectively connected with the driving and driven half diaphragm couplings. Twisting, the formed hole on the diaphragm is to increase the elasticity. Because the elasticity requires the difference between the inner and outer diameters should not be too small, it is generally appropriate to transmit medium and small power.

   5. The characteristics of the diaphragm of the formed diaphragm coupling: each diaphragm coupling is composed of a single diaphragm, and the thickness of the diaphragm decreases regularly from the inner radial to the outer hyperbola to maintain equal strength conditions and its material utilization High, good integrity, especially suitable for high-speed transmission, but the manufacturing precision of the diaphragm is high.

   6. 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.
