The present disclosure relates to generating a modified gear flank geometry on an active surface of the workpiece by generation grinding or honing. In at least one example, the modified gear flank geometry of the workpiece may be generated on the active surface of the workpiece by variation of an engagement depth of a tool into the workpiece in dependence on an angle of rotation of the tool. Additionally, the workpiece may comprise a cylindrical spur gear, a helical gear, a spherical gear, or a conical gear. Further, in one or more examples, the modified gear flank geometry of the workpiece includes at least one of a profile waviness or a defined periodic flank waviness.

The present disclosure relates to a method for the manufacture of a workpiece having a corrected gear geometry and/or a modified surface structure, in particular by a hard finishing process, in particular generation grinding or honing. Provision is made in this respect that it is achieved by a direct generation of a wobble movement and/or of an eccentricity of the tool that a modification, in particular a profile modification or profile waviness, and/or a defined periodic flank waviness is generated on the active surface of the workpiece machined therewith.

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 handheld skate blade sharpening tool that has an automatically indexing, rotating sharpening stone that matches the concaved profile of the skate blade retained within a two-piece body member. Screws hold the two-piece body member together to keep the round sharpening stone sized to match the desired concave profile. The sharpening stone will remove metal to match the shape of the stone each time the sharpener is moved back and forth along the blade. The sharpening stone has gears on each end of the stone that match the gears inside the two-piece body. As the tool is moved along the skate blade, the sharpening stone will incrementally rotate within the body when the direction is changed in the reciprocating motion by the user's back and forth movement.

A method for machining toothed and hardened work wheels, includes: mounting a work wheel that is hardened and pre-toothed with an allowance onto a workpiece spindle; removing at least 50% of the allowance by means of gear skiving with a skiving wheel that is rotatably driven by a tool spindle; precision-machining the work wheel in unchanged tension by means of a honing wheel. The forward movement occurs during gear skiving in the extension direction of the toothing. The delivery of the workpiece that is moved in an oscillating manner in the extension direction of the toothing occurs during honing in the radial direction. The skiving wheel and the honing wheel are driven by a common tool spindle. A device for carrying out the method includes a workpiece spindle, which is driven to rotate, and a tool spindle, which carries a combination tool having a skiving wheel and a honing wheel.

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.
