绪言点接触的交错轴齿轮传功,可用渐开线螺旋齿轮或海波齿轮组成;其中渐开线螺旋齿轮制造容易,即使中心距和轴夹角有一点变动,仍能保持正确啮合。由于螺旋齿轮有这样的特点,所以在交错轴齿轮传动中得到了广泛的应用。但螺旋齿轮的啮合,在理论上是点接触,并且沿齿向有滑动,因此磨损大,所以螺旋齿轮承受的极限载荷不是根据弯曲强度和接触强度决定的,而是根据胶合和磨损决定的;故螺旋齿轮主要用于轻载荷的场合。但是由于最近 INTRODUCTION The point-contact staggered shaft gear transmission can be composed of an involute helical gear or a sea wave gear. The involute helical gears are easy to manufacture and maintain proper engagement even with slight variations in center distance and shaft angle. Because of the helical gear has such characteristics, so in staggered shaft gear drive has been widely used. However, the meshing of helical gears is theoretically point-to-point and sliding along the tooth direction, so the wear is so great that the ultimate load on the helical gear is not determined by the flexural strength and the contact strength, but by the gluing and the wear; Therefore, helical gear is mainly used for light load situations. But recently,
