Abstract

The present invention provides a power skiving method, wherein three-dimensional cutter rotations relative to gear workpiece tooth flank surfaces are carried out so as to reposition the cutter relative to a gear workpiece so as to achieve a decrease and / or an increase in the pressure angle of the tooth flank surfaces. The method can be applied independently to left and right flank surfaces of a tooth slot or the rotations may be superimposed on one another to realize pressure angle corrections on both tooth flanks of a tooth slot.

Description

technical field [0001] This invention relates to the manufacture of gears by power skiving, and in particular to a method of using the inclination of the cutting machine to provide independent pressure angle corrections to the flanks of the gear teeth. Background technique [0002] Skiving of cylindrical gears (also known as "hob stripping" or "power skiving") is a cutting process that has existed for many years, mainly for the manufacture of internal ring gears (see eg DE 243514). Like honing, power skiving utilizes the relative sliding motion between two "cylindrical gears" whose axes are tilted. Power skiving cutters generally look similar to profile cutters with a helix angle (eg 20°) that is different from that of the cylindrical gear being machined (eg US 2011 / 0268523). Other power skiving tools include rod or bar-shaped cutting blades arranged in the cutter head, such as shown in US 2012 / 0282055 or US 9,956,627. Power skiving of internal or external cylindrical gear...
