Abstract
In order to guide supply or construction elements through a harmonic drive ( ) in a central manner, said harmonic drive is embodied in a hollow gear. The harmonic drive directly provides a given correcting translatory variable which is defined by the speed of rotation of the output ring and motor driven harmonic generator when the output ring axially displaces a threaded rod ( ) which freely extends in a coaxial manner through a longitudinal bore in the harmonic drive and engages with said output ring, said axial displacement occurring as a result of the rotational movement of the inner thread of the output ring, whereby the threaded rod is secured to the housing and prevented from rotating ( ). The threaded rod can move in a linear manner in relation to the gear motor ( ) when the gear motor is installed in a stationary manner or when the treaded rod is installed in a stationary manner.
