Abstract

Gearing (1), in particular coaxial gearing or linear gearing, having a toothing (5), a tooth carrier (11) in which there is received a multiplicity of teeth (7) for engagement with the toothing, wherein the teeth (7) are mounted so as to be radially displaceable relative to the tooth carrier (11), a cam disk (20) for the radial drive of the radially displaceably mounted teeth (7), wherein the cam disk (20) has two encircling rims, between which there is arranged a raceway, rolling bodies (23) which are arranged on the running surface between the rims, and a multiplicity of pivot segments (24) which are arranged in encircling fashion on the rolling bearing bodies and which lie in each case by way of a rolling bearing surface against the rolling bodies (23), wherein, on both sides of the rolling bearing surface, there is arranged in each case one rim bearing surface, wherein the two rim bearing surfaces lie at least partially against the rims.
