Method of manufacturing straight bevel gear with continuous indexing

摘要

The invention relates to the production straight bevel gears on CNC Bevel which were previously intended for the manufacturing method of arc-toothed bevel gears.; The invention seeks to provide a method which makes it possible to produce on the already previously available CNC Bevel in the single part or in a continuous process part of straight-toothed bevel gears.; According to the invention this object is achieved in that are used for cutting bevel gears with a tapered tooth height and a hypocycloid as a toothed longitudinal line different circle radii on the one hand for the inner diameter (RWI) and on the other hand, for the outer diameter (RWA) is provided such that, in root plane -dßm helix angle for the left and helix angles are + DSSM generated for the right flanks of a tooth gap, so that more of it is in part the plane of the teeth, a helix angle SSM = 0 ° is obtained for both flanks and is that working with cutter heads whose sequence angle (FOWI) between the inner and outside diameters of a group is smaller than half the diameter group angle (GrWi) that when two cutting heads, which are used for milling a spur bevel gear pair, in each group the first indoor and then cuts the outer diameter.
