摘要
我国的汽车工业发展的非常迅猛，消费者对于汽车的购买欲望和要求不断增加。自从汽车诞生，就汽车的发展看，变速器的发展是其中非常重要的一部分。变速器、发动机和悬架是汽车中传统的三大件。变速器的好坏也是厂商和消费者评价一台汽车性能好坏的重要指标。在汽车的行驶过程中如果变速器质量不好的话，很容易出现顿挫和异响等问题，这会给消费者带来很大的困扰。同时这也降低了车辆的行驶品质。
变速器对于汽车的传动系统异常重要。一辆汽车的油耗怎么样、动力强不强、操纵性好不好都和变速器的性能息息相关。世界在不断进步，汽车设计水平也在不断地提高,变速器的设计趋势为以较小的尺寸和质量传递尽可能大转矩的扭矩,并使传动的过程尽可能的平顺高效本文阐述了一款用于小型suv的手动变速器的设计过程，第二张是关于变速器的整体结构，第三章主要涉及变速器主要参数的选择，第四章主要内容是齿轮的设计和校核，轴的设计与计算在第五章，并完成图纸的绘制。
关键词：变速器；齿轮；轴；轴承；设计；

Abstract
China's auto industry is developing very rapidly, consumers desire for the purchase of cars and increasing demands. Since the birth of the car, the development of the car, the development of transmission is one of the very important part. The transmission, the engine and the suspension are the traditional three pieces of the car. Transmission is also an important indicator of the performance of manufacturers and consumers evaluation of a car performance is good or bad.In the car driving process if the transmission quality is not good, it is prone to setbacks and abnormal sound problems, it will bring great distress to the consumer. At the same time, it also reduces the quality of the vehicle.
The transmission is very important for the transmission system of the car. How a car fuel consumption, power is not strong, good handling and transmission performance are closely related. The world is constantly improving, and the design level of the car is constantly improving. The design trend of the transmission is to transmit as much torque as possible with a small size and mass, and make the transmission process as smooth and efficient as possible. This paper describes a small suv manual transmission design process, the second is on the overall structure of the transmission, the third chapter mainly involves the choice of the main parameters of the transmission, the fourth chapter is the main content of the gear design and verification, The design and calculation of the shaft is done in Chapter five and drawing the drawings
Key Words: transmission;gear; shaft; bearing; design;
