Abstract
A method for producing a toothing with multiple teeth of a gear element for a gas turbine engine including the following steps: predefining a tooth root shape that defines a shape of the toothing in the area of tooth roots of adjacent teeth, wherein the tooth root shape is described by a spline curve at least in certain sections, in particular completely; and forming the toothing with the tooth root shape. A toothing for a gear element includes multiple teeth and a tooth root shape which is formed in the area of tooth roots of adjacent teeth and which is formed according to a spline curve at least in certain sections, in particular completely.

A method for producing a toothing with multiple teeth of a gear element for a gas turbine engine, comprising the following steps:
- predefining a tooth root shape that defines a shape of the toothing in the area of tooth roots of adjacent teeth, wherein the tooth root shape is described by a spline curve at least in certain sections, in particular completely;
- and
- forming the toothing with the tooth root shape.
The method according to claim 1, wherein the spline curve of the tooth root shape has 5 or more than 5, in particular more than 10, control points.
The method according to claim 1, wherein the spline curve of the tooth root shape has an uneven number of control points.
The method according to claim 1, wherein the spline curve of the tooth root shape is an interpolating spline curve.
The method according to claim 1, wherein the spline curve of the tooth root shape is a non-interpolating spline curve and is determined by control points.
The method according to claim 1, wherein forming of the toothing comprises providing a work piece and a cutting machining of the work piece.
A toothing for a gear element of a gas turbine engine, in particular produced by a method according claim 1, wherein the toothing comprises multiple teeth and a tooth root shape which is formed in the area of tooth roots of adjacent teeth which is formed according to a spline curve at least in certain sections, in particular completely.
