Abstract
The utility model discloses a diaphragm coupling, and relates to the field of industrial machinery. The diaphragm coupling comprises a driving axle sleeve and a driven axle sleeve; two sets of diaphragm groups are arranged between the driving axle sleeve and the driven axle sleeve; each diaphragm group consists of two to ten diaphragms which are dish plates with the thickness of 1.8-2.2mm; the two sets of diaphragm groups are connected through a bolt group, and outer sides of the diaphragm groups are fixed to the driving and driven axle sleeves through fastening rings and bolts; joints of the diaphragms, the driving axle sleeve and the driven axle sleeve are provided with locking plates. The relative displacement of the coupling can be compensated by the elastic deformation generated through the stress of the diaphragm groups, the double diaphragm groups can be simultaneously curved to different directions to compensate eccentricity, the number of the diaphragms can be regulated according to project requirements, the fastening rings can prevent looseness between the diaphragms to avoid unstable structure and friction, the locking plates prevent the axle sleeves from being stressed non-uniformly due to the sliding of a connecting key, and the service life is prolonged.
