一、前言锥形同模数渐开线花键齿侧过盈联接是一种不可拆卸联接,也可用于可拆卸联接。由于自身结构特点,其工艺性好、强度高、易于对中,且联接稳定可靠,故广泛用于工作条件比较恶劣、载荷性质复杂的传动场合,如拖拉机和推土机上均已广泛采用。这种联接我国是五十年代引自苏联,长期以来只是按图施工,对其设计计算原理未曾充 I. Introduction Conical conical involute involute spline tooth side connection is a non-removable connection can also be used for removable connections. Because of its structural features, its good technology, high strength, easy to center, and the connection is stable and reliable, it is widely used in the working conditions of the more harsh, complex nature of the load transmission occasions, such as tractors and bulldozers have been widely adopted. This kind of connection to our country is from the Soviet Union in the 1950s. It has only been according to plan construction for a long time, and its design calculation principle has never been filled
