1、浙江工业职业技术学院日期：2009.11 NO26课题10.11 平行轴斜齿圆柱齿轮传动的强度计算目的要求1、掌握斜齿圆柱齿轮的形成和啮合特点；2、理解斜齿圆柱齿轮参数和几何尺寸计算；3、理解斜齿圆柱齿轮的当量齿数和啮合传动；4、理解斜齿圆柱齿轮传动的受力分析和强度计算。重点、难点斜齿圆柱齿轮的形成和啮合特点、几何尺寸计算、受力分析是本次课的重点，而齿轮的当量齿数的理解、啮合传动条件和强度计算有一定的难度。复习提问要点：1、斜齿圆柱齿轮传动有何特点？2、斜齿圆柱齿轮的几何参数有哪些？3、何谓当量齿数？4、斜齿轮的轴向力方向如何判断？教具、实验及教学手段教材、教案、教参等。老师讲解为主（举例、介
