Abstract

A coaxial gear (1), includes an axially oriented tooth system (5) with respect to a rotational axis (3) of the coaxial gear (1), a tooth carrier (7) having axially oriented guideways (9), tooth pins (11) received within the guideways (9) for engaging with the tooth system (5), wherein the tooth pins (11) are axially oriented within the guideways (9) by their respective longitudinal axes and are mounted within the guideways (9) in an axially displaceable manner, and a cam disc (15) rotatable about the rotational axis (3) for axially driving the tooth pins (11), wherein a plurality of bearing segments (17) is disposed between the cam disc (15) and the tooth pins (11) for bearing the tooth pins (11), and wherein, on a side facing the tooth pins, the bearing segments (17) have an elevation at least in sections formed as a spherical cap for bearing the respective tooth pin (11).
