Abstract

A drive, method and a device for determining the torque of a shaft, wherein gear wheels engaged with one another in a gearbox serve to apply an axial force to the shaft, where the axial force is induced by helical teeth of the gear wheels, the axial force of the shaft is determined using a force sensor and/or a position sensor, and where the torque is determined arithmetically from the measured axial force such that a static and dynamic measurement of the torque on the shaft can be advantageously performed.
