我厂生产的DD黄海系列客车底盘、转向摇臂轴是汽车转向机械中的关键零件,如图1所示。轴齿表面粗糙度的好坏直接影响转向力的大小和转向平稳。 以前我厂用Y3180滚齿机加工时,因为轴齿切削角要求7°30′在加工过程中齿全深及7°30′切 I plant the DD Yellow Sea series bus chassis, steering rocker shaft steering gear is the key components in the machinery, as shown in Figure 1. Shaft tooth surface roughness directly affects the size of the steering force and steering smooth. I used to use Y3180 gear hobbing machine processing, because the shaft cutting angle required 7 ° 30 ’in the processing of teeth full depth and 7 ° 30’ cut
