Abstract
Coaxial gear mechanism (1), with a toothing (5) oriented axially relative to a rotational axis (3) of the coaxial gear mechanism (1), a tooth carrier (7) with axially oriented guides (9), teeth (11) which are received in the guides (9) for engagement with the toothing (5), wherein the teeth are oriented with their respective longitudinal axes (13) axially in the guides (9) and are mounted so as to be axially movable in the guides (9), and a cam disk (15) which is rotatable about the rotational axis (3) for axially driving the teeth (11), wherein a plurality of bearing segments (17) is arranged between the cam disk (15) and the teeth (11) for supporting the teeth (11).

A coaxial gear mechanism (1), comprising:
- a toothing (5) oriented axially relative to a rotational axis (3) of the coaxial gear mechanism (1),
- a tooth carrier (7) with axially oriented guides (9),
- teeth (11) which are received in the guides (9) for engagement with the toothing (5), wherein the teeth (11) are oriented with their respective longitudinal axes (13) axially in the guides (9) and are mounted so as to be axially movable in the guides (9), and
- a cam disk (15) which is rotatable about the rotational axis (3) for axially driving the teeth (11),
- wherein a plurality of bearing segments (17) are arranged between the cam disk (15) and the teeth (11) for supporting the teeth (11), and wherein the bearing segments (17) have a plain bearing face (23) for sliding support of the bearing segments (17) on the cam disk (15), and
- wherein at least two of the bearing segments (17) are connected together as a single, integral component.
A coaxial gear mechanism (1), comprising:
- a toothing (5) oriented axially relative to a rotational axis (3) of the coaxial gear mechanism (1),
- a tooth carrier (7) with axially oriented guides (9),
- teeth (11) which are received in the guides (9) for engagement with the toothing (5), wherein the teeth (11) are oriented with their respective longitudinal axes (13) axially in the guides (9) and are mounted so as to be axially movable in the guides (9), and
- a cam disk (15) which is rotatable about the rotational axis (3) for axially driving the teeth (11),
- wherein a plurality of bearing segments (17) are arranged between the cam disk (15) and the teeth (11) for supporting the teeth (11), wherein the teeth (11) each have at least one notch (57), and wherein the bearing segments (17) each have a clip (27) which is designed for form-fit engagement with the at least one notch (57) of the tooth (11).
