Embodiment Construction

[0031] FIG. 1 shows a tooth 1 of a gear which has been machined by means of a honing ring in a method according to the prior art. The honing ring is already moved in one direction along the tooth 1 while maintaining the angle of intersection between the honing ring and the tooth 1 . Accordingly, a surface structure is formed on the tooth 1 , which surface structure each has grooves 3 running substantially parallel to one another on the upper part 5 and the lower part 7 of the tooth 1 . The furrows 3 at the upper part 5 are close to the furrows 3 at the lower part 7 here, but they do not intersect each other. That is to say, channels 9 are formed by the furrows 3 , through which lubricant, for example oil, can be guided away from the tooth 1 under the action of pressure, which occurs, for example, during use in transmissions, and the tooth is correspondingly less responsive to pressure loads. and temperature loads are protected.

Abstract

The present invention relates to a method for creating a surface structure on a gear wheel in a honing process, in which at least one honing tool is moved along the gear wheel in a first direction using a first crossed axes angle, and in which, subsequently, the at least one honing tool is moved along the gear wheel in a second direction, opposite to the first direction, using a second crossed axes angle, and in which the first crossed axes angle and the second crossed axes angle are selected such that first scoring marks produced when the at least one honing tool is moved in the first direction on a surface of the gear wheel at least partially intersect, at a given angle, respective second scoring marks produced when the at least one honing tool is moved in the second direction on the surface of the gear wheel.

Description

technical field [0001] The invention relates to a method for producing surface structures on gears during gear honing, as well as to a gear and to a honing machine. Background technique [0002] Gears are subject to enormous loads due to the very high pressure and friction forces during eg transmission operation. In order to reduce the load on the individual gears and minimize gear noise emissions due to the uniform excitation which causes the teeth to vibrate, the gears are usually surrounded by a film of lubricant, for example an oil film, during operation. [0003] During the manufacture of gears, the teeth of the gears are usually hard-faced by means of honing or grinding methods. Here, a surface structure is created on the teeth of the gear which is not optimally suited to retain the lubricant film applied to the gear on the gear and to ensure the protection of the gear against frictional energy and the reduction of noise . Accordingly, the gear wheels wear out unnec...
