摘要： A method for grinding a gear wheel by a worm grinding wheel in a grinding machine, wherein the tooth flanks of the gear wheel are ground by the abrasive flanks of the profiling of the worm grinding wheel. In order to increase the productivity of the grinding, the method includes the following steps: a) calculating the engagement ratios between the abrasive flanks of the profiling of the worm grinding wheel and the tooth flanks of the gear wheel, wherein the size of the profile forming zone is determined; b) determining a geometry modified in respect of the geometry determined according to step a) such that the profile forming zone is minimal; c) profiling the worm grinding wheel with the geometry which has thus resulted; d) grinding the gear wheel by the worm grinding wheel profiled according to step c).

摘要： 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.

摘要： A method for the dressing of a multi-thread grinding worm by a dressing roll, wherein the grinding worm has at least two screw channels which are arranged parallel to another, which screw channels extend helically around an axis of the grinding worm and wherein the dressing roll has at least two adjacent dressing profiles which are arranged along an axis of the dressing roll, wherein the dressing profiles of the dressing roll are guided simultaneously through adjacent screw channels of the grinding worm during the dressing of the grinding worm. To improve the precision of the dressing the method includes the steps: a) Execution of a first partial dressing process at which the dressing profiles of the dressing roll are guided simultaneously through first adjacent screw channels of the grinding worm; b) Execution of at least one second partial dressing process at which the dressing profiles of the dressing roll are guided simultaneously through second adjacent screw channels of the grinding worm, wherein the second adjacent screw channels are, compared with step a), offset in the direction of the axis of the grinding worm by at least one screw channel of the grinding worm.

摘要： 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.

摘要： A gear grinding unit, capable of grinding a tooth flank of a gear to have fine surface roughness without requiring any special shaping work such as dressing, includes a threaded grinding part which is rotatable around a rotation axis (S1) and engages with a tooth of a gear to be ground. Through a rotational motion of the threaded grinding part, a tooth flank of the gear is ground. The threaded grinding part includes a plurality of flexible abrasive sheets each including a virtual circle having a diameter that equals a root diameter (DA) of the threaded grinding part and a bulge part bulging radially outward from the virtual circle. With the bulge parts of the abrasive sheets mutually shifted around the rotation axis (S1), the abrasive sheets are overlapped along the rotation axis (S1) to form the threaded grinding part.

摘要： A method for manufacturing a screw-shaped tool for grinding a face gear with high precision. The tool is formed in such a manner that the diameter thereof gradually increases from an axial end to an intermediate section in the axial direction, and is used for cutting a face gear. The method includes setting up, on the basis of a prescribed pinion which is to mesh with the face gear to be machined, a virtual gear that is to mesh with the prescribed pinion, and has a greater number of teeth than the prescribed pinion; setting up, on the basis of the virtual gear, a virtual inner gear which has the same number of teeth as the virtual gear, said teeth being on the inside; and setting up, on the basis of the virtual inner gear, a screw-shaped grindstone having various elements that are used for cutting the virtual inner gear.
