Method for Producing Twists on the Tooth Flanks of an Internally Toothed Workpiece
The invention discloses a method for producing modifications, such as twists, on the tooth flanks of an internally-toothed workpiece by an externally-toothed tool. In order to carry out such a method also with machine tools, which have a reduced number of adjustable axes, the invention provides that the tool is dressed by arranging an internally-toothed dressing tool on the workpiece spindle of the machine tool at the position intended for the workpiece to be respectively honed and by bringing the dressing tool into engagement with the tool to be dressed. The width of the teeth of the dressing tool is smaller than the width of the tool to be dressed such that the dressing tool must be moved by a length along the workpiece longitudinal axis which corresponds to a multiple of the width of the teeth of the dressing tool. Subsequently, the fine machining of the workpiece takes place with the tool dressed in this manner. According to the invention, an axis cross angle is set for the dressing, which is maintained unchanged during the dressing. The respective tooth flank modification is then produced during dressing exclusively by movements of the dressing tool along the workpiece longitudinal axis and the workpiece transverse axis.

According to the invention, this is achieved in that both the head surfaces (24) as well as the tooth flanks (25, 26) of the honing tool (20) are machined in at least one advancement of the dressing tool (21') during the dressing process. At the same time, continuous transitions (31, 32) from the tooth flanks (25, 26) to the head surfaces (24) are formed on the honing tool (20) by means of tooth base curvatures (29', 30') provided on the teeth (23, 23') of the dressing tool (21, 21'). By using a honing tool dressed according to the invention, gears can be honed in a corresponding manner, wherein optimal surface finishes with respect to the load-bearing capacity are ensured even in the tooth base regions.

Method for modifying the flanks of a gear wheel tooth with the aid of a tool
The invention relates to a method for modifying the geometry of gear wheel tooth flanks with a tool with a toothing that engages with the gear wheel during a precision machining. A varied profile is produced on the tool over the width of the tool, in that during a dressing procedure a dressing wheel is moved along the tooth flank of the tooth to be dressed. The width of the teeth of the dressing wheel is much smaller than the width of the tool. In order to cover the width of the tool a length must be covered corresponding to a multiple of the width of the teeth of the dressing wheel. After the dressing, the precision machining of the gear wheel is carried out with the tool. Since the dressing wheel is moved with a changing pitch and a changing crossed axes angle relative to the tool, the modification of the tooth flank geometry can be reproduced in the tool. A modification of the crossed axes angle dependent on the helical angle of the tool takes place with equalization of the helical angle of the tool changing over the width of the teeth of the tool.

METHOD FOR MODIFYING THE FLANKS OF A TOOTH OF A GEAR WHEEL WITH THE AID OF A TOOL
The invention relates to a method for modifying the geometry of gear wheel tooth flanks using a tool having a toothing that engages with the gear wheel (ZR) during precision machining. In this case, a profile that varies over the width (Bw) of the tool (1) is produced on the tool (1) in that, during a dressing operation, a dressing wheel (3) is moved along the tooth flank (5) of the tooth (6) to be dressed. The width of the teeth (16) of the dressing wheel (3) is much smaller than the width (Bw) of the tool (1). Therefore, in order to pass over the width (Bw) of the tool (1), it must be moved by a length (L) corresponding to a multiple of the width (BA) of the teeth (16) of the dressing wheel (3). After dressing, the precision machining of the gear wheel (ZR) using the tool (1) takes place. Since, in the process, the dressing wheel (3) is moved with a changing pitch and a changing crossed axes angle (Σ) with respect to the tool (1), the modification of the tooth flank geometry can be transferred to the tool (1). During the subsequent precision machining, a modification of the crossed axes angle (Σ) takes place during the machining process, said modification being dependent on the helix angle of the tool (1), with the helix angle of the tool (1) being compensated, said helix angle changing over the width of the teeth (16) of the tool.
