Abstract

The utility model discloses a spiral adjustment axle clearance's diaphragm coupling. Because the structure of the existing diaphragm coupling is not reasonable, the axial clearance is not convenient to adjust when the coupling is installed and debugged. In order to solve the problems, a worker generally moves a prime motor or a working machine to adjust the size of the axial clearance, but the coupler with the structure still has the problem of poor clearance adjusting effect, so the invention adopts the threaded connection between the external thread sleeve and the internal thread sleeve to adjust the axial clearance, and uses the locking nut to lock after the clearance adjustment, thereby integrally solving the problem of difficult axial clearance adjustment.
