摘要:
In a method of producing a toothed workpiece having a modified surface geometry by a diagonal generating method by means of a modified tool, a tool may be used whose surface geometry comprises a modification which can be described at least approximately in the generating pattern at least locally in a first direction of the tool by a linear and/or quadratic function, with the specific modification of the tool producing a corresponding modification on the surface of the workpiece by the diagonal generating method, with the modification of the workpiece produced by the specific modification of the tool having a profile modification and/or a modification caused by a change of the machine kinematics during the machining process of the workpiece superposed on it.

A process for the making and/or finishing of a crown wheel using a metal-cutting tool, the crown wheel being intended for meshing with a predetermined cylindrical gear. The metal-cutting tool is a rotary disc-type element whose working transverse section lying in the plane of the axis of rotation corresponds essentially to the tooth profile of the cylindrical gear. The disc-type element is placed in such a way relative to the crown wheel to be made that the tooth profile of the element coincides with the tooth profile of the cylindrical gear when it is engaged with the crown wheel. The disc-type element is put into a to and fro linear motion perpendicular to its axis of rotation and is at the same time tilted about an axis which coincides with the axis of rotation of the cylindrical gear when it is engaged with the crown wheel. The tooth profile of the element meshes with the crown wheel to be made and finishes the tooth flanks according to the generating principle.

The straight bevel gear grinding machine of the invention comprises a cradle mounted in the machine base and adapted to impart to the grinding wheel a generating motion, the front and rear faces of said cradle having rectangular holes, wherein guide members are accommodated, adapted for the carriage carrying the spindle with the wheel to be arranged inside the cradle. To impart to the cutting tool an oscillating motion along the tooth space of the gear being machined, the carriage is provided with a driving means mechanically associated therewith.

A tool which can be used for gear manufacturing machining of a workpiece may be dressed on a dressing machine, and the dressing may take place with line contact between the dresser and the tool. A specific modification of the surface geometry of the tool is produced by the suitable selection of the position of the dresser with respect to the tool during dressing. The specific modification of the surface geometry of the workpiece is specifiable with regard to various parameters.
