一、问题的提出齿向误差△F_β是评定齿轮在传动中载荷分布均匀性的重要误差指标,它指的是在分度圆柱面上全齿宽范围内,包容共际齿向线的两条设计齿向线之间的端面距离。测量斜齿轮齿向误差,可利用齿向仪、导程仪或螺旋角检查仪测量,也可利用万能工具显微镜或光学分度头等通用量仪进行螺旋线的点测法来测量齿向误差。使用某些仪器或方法测量齿向误差时,不能直接测出齿向误差,只能测出被测齿轮分度圆螺旋角或基
First, the issue of the proposed gear error △ F_β is to assess the gear load distribution in the transmission of an important error indicator, which refers to the indexing cylindrical surface within the entire tooth width, Design the distance between the ends of the tooth line. Measurement of helical gear tooth direction error can be measured using a tachometer, a lead meter or a helix angle tester, or a universal measuring instrument such as a universal tool microscope or an optical indexer can be used to measure the tangential error. When using some instruments or methods to measure the tooth direction error, the tooth orientation error can not be directly measured, only the measured helix angle or base
