Problems solved by technology

[0015] The contradictory results are: either the bearing capacity is insufficient, and the coupling itself fails prematurely; or the displacement compensation capacity of the coupling is insufficient, resulting in frequent production shutdown accidents of "burning tiles" in complete sets of equipment
There is such a sharp contradiction between the compensation capacity and the carrying capacity of the traditional diaphragm coupling, which makes the design of the coupling difficult and helpless

Description

technical field [0001] The invention relates to a composite special-shaped diaphragm flexible shaft coupling. Background technique [0002] The mission of the flexible coupling is to transmit the torque of the prime mover to the driven machine while compensating the axis misalignment between the shaft of the prime mover and the shaft of the driven machine due to manufacturing errors, installation errors, bearing deformation, thermal deformation, etc. Medium offset. [0003] The "comprehensive transmission capacity" of the flexible coupling not only includes the basic "carrying capacity" required to transmit torque, but also must include the "displacement compensation" caused by the corresponding "displacement compensation" of the laminated diaphragm rod due to the misalignment of the equipment axis. additional bending stress. For field work equipment such as aircraft, boats, vehicle-mounted equipment, or equipment with harsh working conditions, the additional bending stres...
