The new principle to measure the gear whole error with small pressure angle involute worms is presented.

提出了小齿形角渐开线蜗杆测量齿轮整体误差的新原理，阐明了其优点，并进行了原理论证和参数设计计算。

The minimum number of teeth of double involute gear to avoid undercutting is studied in transverse plane.

从端截面出发研究双渐开线齿轮不产生根切的极限齿数，指出在界点切齿啮合时，啮合线并不通过刀尖椭圆中心，进而导出不产生根切的最小齿数计算式，并把齿顶变尖问题与不产生根切的极限齿数结合在一起进行研究，展现了双渐开线齿轮的优越性。

This paper describes a theoretical analysis in accordance with the characteristics and main points of calculating the gear drive with low number of teeth and presents a basis for the rational choice of gear parameters in order to avoid the undercut and pointed teeth of pinions.

对小齿数齿轮传动的特点和计算要点进行分析，为在设计中避免小齿轮发生根切和齿顶变尖，合理选择基本参数提供了依据，并提出了小齿数齿轮传动中最小螺旋角的概
