The invention relates to a propeller shaft assembly tool according to the features in the preamble of claim 1 and a tool set with such a propeller shaft assembly tool.

Cardan shafts are used to transmit torques in non-aligned axes of rotation, for transmitting torques in case of mutually moving parts and for length compensation. An articulated shaft usually consists of two connecting flanges, one or two joints and a rigid or variable in length longitudinal rod, the prop shaft shaft. The present cardan shaft mounting tool is used as a tool or auxiliary tool in the assembly of articulated shaft rods in joints. The propeller shaft rod may, for example, be a drive shaft on steered vehicle wheels. This is a shaft-hub connection with axial securing, in which a hub or a joint or a joint piece is pushed axially onto one end of the propeller shaft rod and axially secured by a locking ring. In the following, the term shaft is used briefly for the cardan shaft rod.

The shaft has on its outer circumference a torque transmission structure in the form of an external toothing and an annular groove. The hub or the joint or joint piece has an internal receptacle with an internal toothing adapted to the external toothing of the shaft. To install the toothed end of the shaft is inserted into the inner receptacle and secured axially there in the position by the retaining ring. The assembly takes place against the radial spreading force of the locking ring.
