Abstract

A shaft connecting mechanism is provided between a slip-on hub and a power takeoff shaft by means of a control ring which extends around the slip-on hub and which is formed to have a pressure screw extend through a threaded bore therein, the pressure screw engaging against a clamping wedge in the slip-on hub which is formed with a trapezoidal configuration generally conforming with the configuration of an axiallly extending groove formed in the slip-on hub. Blocking members are arranged in radial apertures in the slip-on hub and pockets are formed in the control ring. The pressure screw when angularly aligned with the clamping wedge, places the control ring in the locked position and when the pressure screw and the clamping wedge are angularly unaligned, the blocking members enter the pockets in the control ring.
