Through systemic analyzing on spiral helical gear transmission with different basic parameters , the essay found out rules of how can such basic parameters influence spiral helical gear engagement characteristics . so it brings forward the auxiliary assembling mode of adopting one straight gear and one helical gear on condition of little axial angle as well as treasures to ameliorate ill engagement performance on condition of large axial angle , another two jobs of the essay are to clarify the wrong concept that spiral helical gear can only transmit movement but not impetus and to provide a brief and practical method of analyzing contact for gear pairs whose surface equations can be written out directly
通过对不同基本参数的螺旋齿轮传动进行系统研究，找出了螺旋齿轮基本参数对其啮合特性的影响规律，提出小轴交角条件下可采用一直齿轮、一斜齿轮的齿轮副组合方式，给出了大轴交角条件下啮合性能不良的改进措施。澄清了螺旋齿轮只能传递运动不能传递动力的误区，为能够直接写出齿面方程的齿轮副进行齿面接触分析提供了一种简便、实用的新方法。
