A coaxial gear mechanism () includes a toothing () which is oriented axially with respect to an axis of rotation () of the coaxial gear mechanism (), a tooth carrier () which in each case has axially oriented guides (), and tooth pins () which each comprise a body (), which is mounted so as to be axially displaceable in a guide () of the tooth carrier (), and a head region (), wherein the head region () includes at least one tooth () for engagement with the toothing (), and wherein the tooth carrier () wherein the tooth carrier has an irregular angular pitch.

Coaxial gear mechanism

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

Coaxial gear

A gearing, in particular a coaxial gearing or a linear gearing, comprising a tooth system, a tooth carrier having guides, teeth received within the guides for engagement with the tooth system, wherein the teeth are mounted within the guides to be displaceable in the direction of their longitudinal axis relative to the tooth carrier, a cam disk for driving the teeth along the respective longitudinal axis of the teeth, wherein at least one of the teeth respectively has a tooth flank area having tooth flanks, and a tooth body, wherein, between the tooth body and the tooth flanks, one shoulder respectively is provided, which projects back from the tooth body to the inside towards the tooth flank.

Gearing

Gear mechanism, in particular coaxial gear mechanism or linear gear mechanism, having a toothing system, a tooth carrier with radially oriented guides, teeth which are received in the guides for engagement with the toothing system, the teeth being mounted in the guides such that they can be displaced radially relative to the tooth carrier in the direction of their longitudinal axis, a cam disk for radially driving the teeth, the tooth carrier comprising a first tooth carrier part and a second tooth carrier part.
