Abstract
A device for producing a functional shaft and a functional shaft are provided in which a functional element which is provided with a pocket is inserted into a retaining element, a shaft is inserted into the pocket, and a force applied to the functional element while the shaft is being inserted into the pocket is measured.
Claims2
A device for producing a functional shaft, comprising:
- at least two retaining elements, each of the at least two retaining elements being
- configured to hold a respective one of at least two functional elements at a respective predetermined angular position, and
- located axially one after the other at a predetermined axial distance relative to each other;
- and
- a force measuring unit,
- wherein
- each of the at least two functional elements has a pocket configured to receive a shaft, and
- the force measuring unit is configured to independently measure forces applied to the at least two retaining elements and the respective ones of the at least two functional elements held on the at least two retaining elements during axial insertion of a shaft into the pockets of the at least two functional elements, each of the applied forces being useable to determine a value of a torque which the inserted shaft and the respective functional element is capable of withstanding without relative motion between the inserted shaft and the respective functional element.
