Machine with two sections with rotation connection and connected to shaft with inner and outer teeth, reduces misalignment errors

摘要

The machine has a first machine with a rotation connection and a second machine with second rotation connection. A shaft (5) transfers the torque and is connected to both machines. The shaft has outer teeth (6,7) on at least one end and inner teeth (8,9) which grip the machine at this end and allow tilting of the shaft. Neighboring teeth (10) have concave edges.
