Adjustable gap toothed coupling

Abstract

The utility model relates to the technical field of coupling clearance adjustment, and disclose a tooth coupling of adjustable clearance, including two groups of shell. The tooth coupling of adjustable clearance, through the setting of the inner gear, the external gear and the pusher assembly, there will be a certain clearance between the inner gear and the external gear under the installation or long time use of coupling, at this moment, rotate the rotary valve, the rotary valve rotation drives the screw rod to rotate, the limiting sleeve rotates in the inside of the sleeve, the inner gear moves on the screw rod when the screw rod rotates, since the inner gear and the external gear tooth surface are all conical, when the inner gear moves, the inner conical tooth surface and the conical tooth surface of the external gear will change the degree of adhesion, through the accurate control of the moving distance of the inner gear, can make the tooth surface that originally exists the clearance realize the close meshing again, make the cooperation clearance between the inner gear and the external gear be eliminated, thereby reach the purpose that adjusts and compensates the clearance, guarantee the stability and precision of coupling transmission.
