Abstract
In order to guide supply or construction elements through a harmonic drive (8) 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 (26) 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 (29, 30). The threaded rod can move in a linear manner in relation to the gear motor (13) when the gear motor is installed in a stationary manner or when the treaded rod is installed in a stationary manner.
