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.
