This study refers to the conditions of practical powder metallurgy manufacture process, and proceeds to experiments and gear precision measurements as well as investigation on the effects of two parameters, powders and pitch circle radius, on gear precision. The relationship between gear parameters and gear surface deviations was derived from the mathematical model for the involute helical gears and the analysis of gear surface deviations.

本论文将采用实际上粉末冶金螺旋齿轮的制程条件，进行试作实验与齿轮精度的量测，以探讨粉末及螺旋齿轮之节圆半径这两个制程参数对於齿轮精度的影响；同时应用齿轮创成原理所推导之螺旋齿轮数学模式，配合齿面变异分析，求得齿轮设计参数改变量与齿面变异量之关系。
