Abstract

Gearing (1), in particular single-stage gearing having a transmission ratio of greater than 1 to 10, having an internal gear (2) with an internal toothing (5), a first toothed ring with radially movable first teeth (6) for engaging into the internal toothing (5), a second toothed ring with radially movable second teeth (7) for engaging into the internal toothing (5), an inner shaft (21) on which is fastened a first cam disk (16) for the radial drive of the first teeth (6) and a second cam disk (17) for the radial drive of the second teeth (7), and a load dividing device for dividing a torque transmitted via the toothed rings between the toothed rings.
