弧齿锥齿轮尖齿刮削刀盘的齿形优化设计

Optimized design and reshaping of skiving cutter with plane flank for gleason gear

采用尖齿刮削刀盘对弧齿锥齿轮硬齿面进行刮削加工时,刀盘切削刃采用斜角直线造形法,切削刃较大刀具造形误差和重磨误差较大。充分分析各种参数对刀具造形误差和重磨误差的影响,合理选取刀具参数,是促进硬齿面刮削加工工艺广泛应用的关键。本文提出了优化尖齿刮削刀盘造形的方法,并对影响刀盘造形误差和重磨误差的参数进行了全面分析,得出了选取造形参数的基本规律。

Because the profile of skiving cutter with plane flank for Gleason gear is a straight line with an angle λ,the tolerance of the designed profile and the tolerance of the reshaped profile are great. In this study,a method of optimizing the profile has been put forward, with which the parameters that have effect on the above two tolerance,have been analyzed. As a result, a basic rule on the parameters of the profile design has been obtained.
