Abstract

The utility model discloses a cage type diaphragm coupling. The diaphragm coupler with the existing structure can not adapt to large angular displacement, axial displacement and radial displacement, so that the application range of the coupler is limited; or the diaphragm is easy to generate fatigue damage under the repeated action of large angular displacement, axial displacement and radial displacement. In order to solve the problems, the cage type diaphragm coupling structure is invented, the use requirement of a user is met by utilizing the characteristic of strong displacement compensation capability of the cage type structure, and the additional load acting on the diaphragm is reduced.

The utility model relates to a mechanical transmission's shaft coupling is motion, power transmission's draw bail between prime mover (like motor, internal-combustion engine etc.) and the working machine (like pump, speed reducer etc.), belongs to mechanical transmission technical field.
Background
The coupling is widely used in rotary machines, and includes a rigid coupling, an elastic coupling, and the like. The diaphragm coupling is a novel coupling, has the advantages of transmitting larger torque, allowing larger displacement error, allowing high-speed rotation, relaxing impact vibration, generally not needing lubrication, being convenient for installation and maintenance and the like, is widely applied to industries such as national defense, shipbuilding, aviation, petrochemical industry, vehicles, machinery and the like, and can replace coupling devices such as gear couplings, elastic sleeve pin couplings and the like. However, because the structure of the existing diaphragm coupling is not reasonable, the angular displacement, the axial displacement and the radial displacement which can be compensated can not meet the requirements of users sometimes; or when the coupler is under the repeated action of large angular displacement or axial displacement and radial displacement, the diaphragm is easy to generate fatigue damage, and the service performance and the service life of the coupler are directly influenced. In order to solve these problems, researchers generally compensate displacement through local deformation of the diaphragm set, but the coupler with such a structure still has poor effect of compensating overall displacement, so that a more reasonable diaphragm coupler needs to be invented.
