Description

technical field

[0001] The invention relates to a high-speed, high-torque waveform diaphragm disc flexible coupling, in particular to a high-speed, high-torque coupling, which belongs to the technical field of transmission equipment. Background technique

[0002] At present, in the field of industrial transmission, the membrane disc 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 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 ...
