GEAR SYSTEM, IN PARTICULAR A HARMONIC DRIVE GEAR SYSTEM AND METHOD FOR OPERATING A GEAR SYSTEM

摘要

The invention relates to a gear system, in particular a harmonic drive (1), comprising at least two components (2, 3) that are posistively coupled, preferably by means of peripheral teeth (4), or frictionally-coupled, preferably by means of friction surfaces, for transmitting a rotational displacement and/or for converting a rotational displacement into a translatory displacement with an optional rotational displacement. Said gear system also comprises a deformation unit (5), which is used to elastically deform at least one of the components (2, 3) in such a way that the components (2, 3) only interact with one another in at least two areas (19, 20; 22) and by means of which the components (2, 3) are displaced in relation to one another. According to the invention, the deformation unit (5) has actuators (14, 15) that generate a tractive force and are applied to the component(s) (2) between the aforementioned areas (19, 20; 22). The invention also relates to a method for operating a gear system of this type.
