High-speed and large-torque waveform membrane disc flexible coupling

Abstract

The invention relates to a high-speed and large-torque waveform membrane disc flexible coupling and belongs to the technical field of driving equipment. The high-speed and large-torque waveform membrane disc flexible coupling comprises flexible mounting discs, adapting discs, locating rings and a spacing shaft, wherein the spacing shaft is located with the adapting discs by the locating rings and is connected with a transmitted torque through a second bolt assembly; two groups of the flexible mounting discs and the adapting discs are symmetrically arranged at two ends of the spacing shaft; the transmitted torque is connected between the flexible mounting discs and the adapting discs by a first bolt assembly; the flexible mounting discs are of integrated structures and specially comprise mounting discs and membrane discs; a molded surface of each membrane disc consists of a special curved surface feature between a molded surface outer ring and a molded surface inner ring and forms a waveform curved surface; and the axial thickness of the molded surface of each membrane disc is gradually increased from the molded surface outer ring to the molded surface inner ring. The high-speed and large-torque waveform membrane disc flexible coupling disclosed by the invention has the advantages of high torque transmitting capability, high rotating speed capability, high axial compensation capability, good dynamic balance retentivity, simple structure, light weight, and convenience and quickness in mounting, and has a safe flying preventing structure.

[0002] At present, in the field of industrial transmission, the diaphragm flexible coupling has been widely used to undertake the power transmission of high-speed industrial equipment with a speed above 10,000r / min. Although the coupling has certain axial, angular, and radial compensation capabilities, the torque transmission capacity is not strong due to the influence of structural instability on the plate and shell type surface of the traditional technology diaphragm; the traditional technology with large torque transmission capacity The diaphragm flexible coupling has large size, large moment of inertia, large centrifugal stress, and heavy weight, which also increases the additional load of the unit, making the torsional vibration calculation of the unit shaft system unable to pass, so the traditional diaphragm flexible coupling cannot meet the requirements. Actual demand for high-speed and high-torque units
