Abstract
A gearbox (1), in particular coaxial gearbox, includes a ring gear having an internal toothing (3); a tooth carrier (5) having guides (7) which are aligned radially in terms of a rotation axis of the gearbox; teeth (9) which, for engaging with the internal toothing (3), are received in the guides (7), wherein the teeth (9) are mounted in the guides (7) displaceable in the direction of their longitudinal axis (11) relative to the tooth carrier (5); and a cam disk (13) which is rotatable about the rotation axis and is operatively connected to the teeth (9); wherein the teeth (9) have in each case a tooth flank (17) which is at least partially curved along a width curve (51) extending over a width (41) of the tooth flank (17).

A gearbox (1), comprising
- a ring gear having an internal toothing (3);
- a tooth carrier (5) having guides (7) which are aligned radially in terms of a rotation axis of the gearbox;
- teeth (9) which, for engaging with the internal toothing (3), are received in the guides (7), wherein the teeth (9) are mounted in the guides (7) displaceable in the direction of their longitudinal axis (11) relative to the tooth carrier (5);
- and
- a cam disk (13) which is rotatable about the rotation axis and is operatively connected to the teeth (9);
- wherein the teeth (9) have in each case a tooth flank (17) which is at least partially curved along a width curve (51) extending over a width (41) of the tooth flank (17), and wherein the tooth flank (17) has two peripheral regions (49) along the width curve (51) over the width (41) of the tooth flank (17), and a central region (47) between the two peripheral regions (49), wherein the tooth flank (17) in at least one peripheral region of the two peripheral regions (49) is recessed inward in relation to the central region (47).
A gearbox (1), comprising
- a ring gear having an internal toothing (3);
- a tooth carrier (5) having guides (7) which are aligned radially in terms of a rotation axis of the gearbox;
- teeth (9) which, for engaging with the internal toothing (3), are received in the guides (7), wherein the teeth (9) are mounted in the guides (7) displaceable in the direction of their longitudinal axis (11) relative to the tooth carrier (5);
- and
- a cam disk (13) which is rotatable about the rotation axis and is operatively connected to the teeth (9);
- wherein the teeth (9) have in each case a tooth flank (17) which is at least partially curved along a width curve (51) extending over a width (41) of the tooth flank (17), and wherein the width curve (51) extends symmetrically in terms of a center of the width (41) of the tooth flank (17).
A gearbox (1), comprising
- a ring gear having an internal toothing (3);
- a tooth carrier (5) having guides (7) which are aligned radially in terms of a rotation axis of the gearbox;
- teeth (9) which, for engaging with the internal toothing (3), are received in the guides (7), wherein the teeth (9) are mounted in the guides (7) displaceable in the direction of their longitudinal axis (11) relative to the tooth carrier (5);
- and
- a cam disk (13) which is rotatable about the rotation axis and is operatively connected to the teeth (9);
- wherein the teeth (9) have in each case a tooth head (15), wherein a tooth head width curve (53) extending along the tooth head (15) and over a tooth width (43) of the tooth (9) is at least partially curved in the direction of the longitudinal axis of the tooth.
