Abstract
Method for machining right toothed bevel gears, wherein: at least a part of the tooth flanks is milled with a disc milling cutter, the left tooth flanks are milled at a different time than the right tooth flanks, the machined bevel gear is rotated by an angle between the milling process of at least one left tooth flank and the milling process of at least one right tooth flank, the inclination of the axis of the disc milling cutter remains unchanged during the milling process of said gear, said angle being not a multiple of the base pitch α.
Claims15
Method for machining bevel gears with a C-axis and a base pitch, said bevel gear comprising teeth having a head and flanks with a certain profile, said flanks comprising left flanks and right flanks,
- at least part of said left flanks and part of said right flanks being milled with a disc milling cutter comprising a single milling head, said milling head having a milling head tooth,
- the said left flanks being milled at a different time than the said right flanks,
- the bevel gear to be machined being rotated by a predefined angle between the milling process of at least one of said left flanks and the milling process of at least one of said right flanks,
- said predefined angle being not a multiple of said base pitch,
- said profile of said flanks being corrected through an angular displacement of said machined bevel gear and/or through an axial displacement of said milling cutter.

- said predefined angle being not a multiple of said base pitch α,
- said disc milling cutter being displaced axially by a distance equals the width of said milling head tooth in the pitch circle between the milling process of at least one of said left flanks and the milling process of at least one of said right flanks,
- said profile of said flanks being corrected through an angular displacement of said machined bevel gear and/or through an axial displacement of said disc milling cutter.
