In this paper, we proved that there exists only one contact point between a pair of non-circular gears working under the designed pitch curves when they are manufactured by involute cylindrical gear cutter in numeric control slotting machine. Under this manufacturing condition, the pair of non-circular gears can mesh accurately.

证明了采用渐开线圆柱齿轮刀具在数控插齿机上加工的1对非圆齿轮副传动时，在其按设计的已知节曲线工作时，两非圆齿轮副的齿廓具有单一的接触点，即能保证正确的啮合关系，为深入分析非圆齿轮副的传动机理提供了前提。
