摘要在现代汽车驱动桥上，主减速器的功用是将输入的转距增大并相应降低转速，以及当发动机纵置时还具有改变转矩旋转方向的作用。单级主减速器通常由主动齿轮和从动齿轮组成。在双级主减速器中，通常还要加一对圆柱齿轮或一组行星齿轮。在轮边减速器中则常采用普通平行轴式布置的斜齿圆柱齿轮传动或行星齿轮传动。主减速器采用的最广泛的是螺旋锥齿轮和双曲面齿轮。在某些公共汽车和重型汽车上有时也选用蜗轮传动。本文首先确定主要部件的结构型式和主要设计参数；然后参考类似驱动桥的结构，确定出总体设计方案；最后对主，从动锥齿轮，差速器圆锥行星齿轮，以及对支承轴承进行了寿命校核。本文采用传统的双曲面锥齿轮式单级主减速器作为 CA1050 的主减速器。关键词: CA1050； 主减速器； 双曲面锥齿轮； 轴承； 行星齿轮ABSTRACTNowadays, the main reducer, which on modern car driving axle, is used to increase the imported torque and correspond to decrease its speed, at the mean while, it also can change the direction of torque when engine is longitudinal. Single-stage reducer is usually composed of the main driving gear and driven gear. In main two-stage reducer, a spur gear or a group of planetary gear also included. In the wheel-side reducer, helical gears drive or planetary gear is adopted, which is laid of common parallel coaxial. spiral bevel gear gear and hypoid gears are broadly adopted by main reducer. Worm transmission is used by some buses and trucks. In this paper, the structure of main components and the main design parameters are first to confirm; and then refer to similar driving axle structure, and identify the design parameters; Finally, check the main, driven bevel gear, cone planetary and the whole floating half-axle and then check the life of bearing. In this paper, using the traditional hypoid gears as the main CA1050 reduc
