Abstract

The invention discloses an elastic coupling with a composite material membrane disc. The elastic coupling comprises an elastic element, a flange and the membrane disc, wherein the membrane disc is made of a composite material; at least one portion of the membrane disc is located between the elastic element and the flange in the axial direction of the elastic coupling; the membrane disc comprises afirst extension section, a second extension section and a deformation section; the first extension section is connected with the flange; the second extension section is arranged on the radial outer side relative to the first extension section; the second extension section is connected with the elastic element; the deformation section is connected with the first extension section and the second extension section; and the deformation section is corrugated and can deform elastically. The elastic coupling disclosed by the invention comprises the elastic element, the flange and the membrane disc,by the elastic element, large radial displacement compensation can be realized, the membrane disc is light and has the characteristics of sound insulation, vibration reduction, noise reduction, high strength, impact resistance, corrosion resistance and the like, and by the membrane disc, large axial displacement compensation and angular displacement compensation can be realized well.

Description

technical field [0001] The invention relates to the technical field of transmission, in particular to an elastic coupling. Background technique [0002] As a power transmission element, the coupling can be used to connect the main engine and the working machine, so that the torque and speed output by the main engine are transmitted to the working machine through the coupling. Metal shafts and couplings are often used as transmission parts in modern ship power transmission systems. As modern drivetrains move toward higher power and higher torque, product weight will increase accordingly. However, the heavy coupling will increase the burden on the main engine, which will lead to increased wear between the main engine and the coupling, increased noise, and excessive arm distance difference, which seriously affects the performance and life of the main engine. Therefore, reducing the weight of the coupling has become an urgent problem to be solved in the development of modern p...
