Abstract: In order to be able to quickly detect the phase between the outer tooth profile and the internal spline in the gear machining. In this paper, a set of craft equipment of phase detection of gears with high efficiency has been designed in a self-centering way. It is easy to operate and easy to use. Not only can meet the detecting needs of the production site by a more convenient and fast way, but also the processing workers do not require high skills. Through field test inspection, we found that the Tooling has great results in use and the test of production on site can replace the existing detection methods which is more complicated. It has the certain popularization value. We have been applied for the invention patent.

目前齒轮类零件的加工方法多种多样,包括滚齿、插齿、剃齿、线切割等加工方法[1,2]。在单纯的加工外齿或内齿的时候针对不同的精度和加工要求选择不同的加工方法,完全可以满足生产加工的需要。但有些时候,零件同时具有外齿和内花键的加工要求且同一零件上的内外齿形具有相位要求。所谓相位要求即是指外齿廓的任一齿顶(或齿底)与基圆圆心的连线和内花键齿廓的任一齿顶(或齿底)与基圆圆心的连线,两条直线共线或成某一角度。如图1所示,图中所示齿轮的外齿廓的某一齿顶与基圆圆心的连线和内花键某一齿底与其基圆圆心的连线在同一条直线上。具有这种加工要求的零部件,加工时由于装夹工装或操作不当的原因,两根连线会有不可避免的偏差[3,4]。当然,这个偏差是有允许范围的,在误差允许范围之内的可以当作成品使用,超出偏差的当然要剔除。……
