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.

Gear

A coaxial transmission, especially a hollow shaft drive, comprising a driving element () and a driven element (), a plurality of radially mobile toothed quadrants () providing a gear ratio and transmitting a driving torque between the driving element () and the driven element (). An internal gear () or especially the housing for receiving the inner gearing of the internal gear () are configured as a multipart structure.

Coaxial transmission

A coaxial transmission, especially a hollow shaft transmission for industrial drive engineering, having a high power density. The transmission comprises an input element (), an element () and an output element, a drive torque being multiplied and transmitted between the input element () and the output element via a plurality of radially mobile toothed sections (). At least one toothed section () has a bearing element () which is enlarged in its effective zone with respect to an input element ().

Coaxial transmission, especially hollow shaft transmission for industrial drive engineering

A conical gear drive comprising an input element that interacts with a truncated conical gear via which an output element can be driven. A number of different output elements or variably selectable output elements should be able to be connected to the truncated conical gear drive.

The aim of the invention is to provide a simple, safe to handle fixing device for a par that can be inserted between adjacent supports, especially centrally. Locating holes that are aligned approximately flush with each other, for holding elements of the part are provided in the adjacent supports. The holding elements are configured in the form of pegs mounted in the part. The pegs are provided with a screw thread at their second ends and each engage in a corresponding screw of sliding pieces that can slide in the part. The sliding pieces can be slid and stopped in a plane defined by the longitudinal axes of the pegs. The part has at least one pair of pegs on opposite outer surfaces that are flush with each other through the part.
