Abstract

A coaxial transmission, especially a hollow shaft transmission for industrial drive engineering, having a high power density. The transmission comprises an input element (7), an element (3) and an output element, a drive torque being multiplied and transmitted between the input element (7) and the output element via a plurality of radially mobile toothed sections (5). At least one toothed section (5) has a bearing element (11) which is enlarged in its effective zone with respect to an input element (7).
