Abstract:
1. A gearing, in particular coaxial gearing, hollow-shaft gearing, hypoid gearing or axial gearing, having a drive input element, a drive output element, and an element between the drive input element and the drive output element, and a multiplicity of movable tooth segments provide a transformation and a transmission of a drive torque between the drive input element and the drive output element, wherein the multiplicity of tooth segments are moved by means of the drive input element, wherein the drive input element is embodied as an element which is driven in rotation, and has a profiling in order to move individually radially arranged and movable tooth segments with respect to the element or the drive output element, wherein the multiplicity of tooth segments can be moved in a linear, rolling or lifting fashion directly or indirectly by means of an outer profiling of the drive input element, wherein the profiling forms at least two elevations, wherein at least two groups of tooth segments engage simultaneously into the toothing, wherein at least one bearing arrangement as roller bearing arrangement is provided between the profiling of the input drive element and the tooth segments, with the tooth segments being coupled to a position of an outer contour of the drive input element.
