ABSTRACT:
A transmission shaft assembly of the cardan type for transmitting torque from an input to an output includes a pair of universal joints with an intermediate connecting shaft between the joints. The universal joints are connected to the intermediate shaft on one side and a first coupling flange is connected to each universal joint on its other side. A second coupling flange is detachably connected by screw bolts to the first coupling flange of each universal joint, and each coupling flange has a plane end face with at least two groups of axially projecting gear teeth for torque transmission coupling between the flanges. The teeth of each group on each flange extend in a direction parallel to one another and have inclined side walls for engagement with the side walls of the teeth of the cooperating flange. The end face of one of the flanges of a cooperating pair has at least one raised flat surface between a pair of groups of teeth and the other flange has recessed surfaces between its groups of teeth for receiving the raised flat surfaces of the first flange. A clearance space is provided between cooperating raised flat surfaces and recessed surfaces and between the crests of the teeth of one of the flanges and bottoms of the valleys of the teeth of the other flange.
