pitch curve

基本解释

The proposed graphical method may directly plot the cam profile without plotting its pitch curve, therefore its construction is more simplified and more accurate.
这种作图法可以直接求出凸轮的实际轮廓曲线而毋须绘制其理论轮廓线，因而使作图简化精确。
Appropriate pitch curve designing is a key of regularly working for non-circular planetary gear mechanism with variable center distance which can be used in low speed high torque hydraulic motor.
合理的节曲线设计是可用于低速大扭矩液压马达的变中心距非圆行星齿轮机构正常工作的关键。
According to the fundamentals that pure-rolling must take place between the pitch line of hob and the pitch curve of gear workpiece, the 4 axis complicated simultaneous-control relation was obtained.
从滚刀节曲线与齿轮工件节曲线之间必须进行纯滚动出发，推导出联动关系为4个坐标的复杂联动。
