Abstract

The invention belongs to the field of mechanical power transmission, and relates to a structural design manufacturing process of a coupling combined diaphragm, in particular to a coupling diaphragm applicable to various transmission equipment. The coupling combined diaphragm is provided with sheet metal, and is mainly characterized in that 2-30 layers of sheet metals are fixed by 6-16 bolted hole sleeves and collars, and are wrapped in a matrix; the matrix is made of composite material of synthetic rubber, synthetic plastics or synthetic fibers. As the diaphragm is a transmission part of a coupling, and mainly has the effect of transmitting torque, the structure of the original metal diaphragm is not changed. The coupling combined diaphragm has the characteristics that the manufacturing is easy, the cost is low, the elasticity and the resilience are good, the heat resistance is good, particularly, and the ambient atmosphere corrosion resistance is strong. The service life and the safety of the coupling combined diaphragm substantially exceed those of the original metal diaphragm, and coupling combined diaphragm achieves the upgrading of coupling combined diaphragms applicable to various transmission equipment.

Description

Technical field: [0001] The invention belongs to the field of mechanical power transmission, and in particular relates to a structural design and manufacturing process of a composite diaphragm of a shaft coupling. Coupling diaphragms suitable for various transmission equipment. Background technique: [0002] The structure of the metal diaphragm coupling is mainly composed of a metal diaphragm group, a flange, a shaft at both ends, an intermediate shaft and connecting bolts. It is a two-axis flexible connection device between the driving machine and the driven machine of the transmission equipment. At present, the commonly used structures are ring type, multilateral type and waist type. The advantages of the coupling are: high rigidity of torque transmission; large deflection compensation ability in the axial and angular directions; and certain vibration absorption and damping effects; and no lubrication, long life, high transmission efficiency, It has energy-saving effect....
