摘要
在汽车行驶时的动力传递过程中,变速器是其中的重要环节。汽车变速器是汽车传动系统的主要组成部分,主要作用是将发动机的转矩经过改变后传递给主减速器,最终将动力有效而经济地传至驱动车轮,以满足汽车的使用要求。设置空档用来中断动力传递,设置倒档,使汽车能够倒退行驶。
本设计以现有企业正在生产的远舰汽车变速器为基础,在给定发动机输出转矩、转速及最高车速、总质量、车轮滚动半径等条件下,着重对变速器齿轮的结构参数、轴的结构尺寸等进行设计计算;并对变速器的传动方案和结构形式进行设计;同时对操纵机构和同步器的结构进行设计;从而提高汽车的整体性能。
文中对变速器的主要参数进行验证,包括齿轮强度的校核、变速器轴强度和刚度的校核、轴承寿命的验算等,计算结果表明整体性能满足要求。

ABSTRACT
In the process of power delivery of the auto movement, transmission is the necessary link. Auto transmission is the ponent of the drive train, the main effect is to transfer torque from engine to final drive through by changing gear ratio is to expand the scope and speed to adapt to the driving conditions effectively and economically. Setting neutral is to interrupt power transmission; Setting up to reverse, the vehicle can drive back.
The design based on the existing enterprises production Yuanjian Transmission, In conditions that knowing the engine output torque speed of engine and maximum speed of vehicles, maximum degree, focus on the designing of transmission gear structural parameters, axis geometry putation; as well as the transmission and drive program structure design; Meanwhile on the structure ponents to manipulation and synchronous design; thereby enhancing the overall performance of cars.
The main parameters for transmission have been checked, including the strength of gear, the transmission shaft strength and stiffness of the coupling, Bearing life, results show overall performance meet the requirement.
