Abstract
A coaxial gear mechanism (1) includes a toothing (5) which is oriented axially with respect to an axis of rotation (3) of the coaxial gear mechanism (1), a tooth carrier (7) which in each case has axially oriented guides (9), and tooth pins (11) which each comprise a body (50), which is mounted so as to be axially displaceable in a guide (9) of the tooth carrier (7), and a head region (51), wherein the head region (51) includes at least one tooth (52) for engagement with the toothing (5), and wherein the tooth carrier (7) wherein the tooth carrier has an irregular angular pitch.
Claims11
A coaxial gear mechanism (1), comprising:
- a toothing (5) which is oriented axially with respect to an axis of rotation (3) of the coaxial gear mechanism (1),
- a tooth carrier (7) which has axially oriented guides (9), and
- tooth pins (11) which each comprise a body (50), which is mounted so as to be axially displaceable in a guide (9) of the axially oriented guides (9) of the tooth carrier (7), and a head region (51), wherein the head region (51) comprises at least one tooth (52) for engagement with the toothing (5),
- wherein the tooth carrier has an irregular angular pitch, wherein the irregular angular pitch comprises a group of identical first angles (57) between adjacent guides (9) and at least one second angle (59), which is different from the first angles (57), between adjacent guides (9).
A method for producing a coaxial gear mechanism (1) from a range comprising a plurality of coaxial gear mechanisms having different transmission ratios, wherein the coaxial gear mechanism (1) comprises:
- a toothing (5) which is oriented axially with respect to an axis of rotation (3) of the coaxial gear mechanism (1),
- a tooth carrier (7) which has axially oriented guides (9), and
- tooth pins (11) which each comprise a body (50), which is axially displaceably mounted in a guide (9) of the axially oriented guides (9) of the tooth carrier (7), and a head region (51), wherein the head region (51) comprises at least one tooth (52) for engagement with the toothing (5),
- wherein the method comprises:
- selecting the tooth carrier (7) from a plurality of tooth carriers, wherein the tooth carriers each have different angular pitches of the axially oriented guides (9) for realizing the different transmission ratios, and
- mounting the coaxial gear mechanism (1) with the toothing (5), the tooth carrier (7) and the tooth pins (11).
