Abstract
Gear mechanism (1), in particular coaxial gear mechanism, having an internal gear (3) with an inwardly directed toothing (5), a tooth carrier (11) which is arranged coaxially with respect to the internal gear and in which a multiplicity of teeth (7) for engaging with the toothing (5) are accommodated, wherein the teeth (7) are mounted radially displaceably in the tooth carrier (11), a drive element with a profiling (22) for radially driving the radially displaceably mounted teeth (7), wherein the profiling (22) has, over its circumference, at least two elevations, wherein the gear mechanism is constructed such that there is a positive transmission ratio between a drive via the drive element and an output via the tooth carrier (11).
