A method for producing honing tools (24) that are conjugate to the bevel pinions and ring gears (26) they are intended to hone and which can be produced (e.g. cut) on a standard bevel gear free form machine. The method is described by two transformation steps with the basis of the transformations being the theoretical generating gear. The invention relates also to a toothed bevel honing tool produced by such a method and a method of honing bevel gears when provided with such a tool produced by such a method.

A method for machining the tooth flanks of a bevel gear workpiece includes carrying out correction machining of a concave tooth flank and a convex tooth flank of at least one tooth gap by, after machining using a first machine setting, cutting free of the concave tooth flank by the bevel gear workpiece executing a workpiece rotation in a first rotational direction having a predefined first absolute value in relation to a gear-cutting tool and/or cutting free the convex flank by the bevel gear workpiece executing a workpiece rotation in another rotational direction having a predefined second absolute value in relation to the gear-cutting tool, and finish machining the concave tooth flank using a second machine setting, which differs from the first machine setting, and finish machining the convex tooth flank using a third machine setting, which differs from the second machine setting.

A machine for honing gears comprises a workpiece spindle, the spindle axis of which is oriented vertically, wherein a workpiece to be machined is attachable in the region of a free end of the workpiece spindle, a honing ring carrier in which a honing ring for machining the workpiece attached to the workpiece spindle is clampable and is drivable in rotation about its central axis, and a machine frame on which the workpiece spindle and the honing ring carrier are mounted. The machine frame surrounds the honing ring carrier. The honing ring carrier is additionally mounted at two bearing points on the machine frame, said bearing points being substantially diametrically opposite one another with regard to the honing ring carrier, so as to be movable linearly along a horizontal axis which extends through the bearing points and so as to be movable in rotation about this axis. The machine has a simple and compact structure. The machine frame serves not only as a structural element for mounting the individual components of the machine and all required shafts, but at least partially also to form a working space in which the machining takes place.

A method for honing processing a toothed wheel in which the toothed wheel and a honing tool mesh with each other and the rotation axes of the toothed wheel and honing tool intersect at an axial intersection angle. The toothed wheel and honing tool carry out a relative movement which oscillates in an axial direction of the rotation axis of the toothed wheel and are positioned in a direction towards each other at the same time in a radial direction with respect to the rotation axis of the toothed wheel starting from an end position in order to remove material from the toothed wheel. During the oscillating relative movement which is directed in an axial direction of the rotation axis of the toothed wheel, the rotation position of the toothed wheel with respect to the rotation axis thereof is changed in accordance with the positioning in a radial direction.

Method for cutting a gear (4) from a metal workpiece (2), in which a tooth flank, still having an oversize compared with its predefined final geometry, of the gear is, in one or more cutting passes in cutting engagement with one or more cutting tools (10) fed thereto, hard-fine finished with a geometrically undefined cutting edge made of cutting grains incorporated in a binder matrix, in order to produce a reflective property, existing in the final geometry, of its surface, wherein, in a cutting pass of a cutting tool (10b), both an elastically resilient mounting of the cutting grains set by its binder matrix acts on this surface property, and a cutting reduction of the oversize by at least 2 m at the tooth flank is realized by a compressive preload, set via the infeed of the cutting tool, to which the cutting engagement is subjected; as well as a gear-cutting tool and a machine tool for this purpose.

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 chosen 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.

A method for dressing a honing tool using a dressing tool which during the dressing operation rolls at an axial intersection angle with the honing tool. The teeth thereof which move into engagement with the teeth of the dressing tool each have an upper face which is to be dressed and tooth flanks which are also to be dressed.
