摘要

汽车齿轮变速箱是汽车重要的变速传动装置,汽车齿轮变速箱结构形状复杂,存在应力集中现象。应力集中导致的高应力直接影响着变速箱的使用寿命,还可能使箱体发生开裂。针对汽车齿轮变速箱壳体进行了静态转矩加载试验,测得铸铝壳体的应力应变情况,并对箱体关键部位测得的数据进行单向应力分析,找出变速箱壳体在实际工作状态下应力集中的部位。为汽车齿轮变速箱的设计制造等提供重要的试验依据。

Abstract

A gear- box is the important continuously variable transmission in light truck. The structure and shape of a gear- box is particular complex and the phenomenon of stress concentration exists. And the high stress caused by stress concentration will directly affects the lifetime of a gear- box,even leads to crack. The structure strength of gear- box is studied through the experiment of static torque loading. The data of stress-strain characteristics of the cast aluminum shell is collected. And those data are analyzed with unidirectional stress method to find the stress concentration positions of a gear- box in its practical working conditions. Those analysis provide an important experimental basis for designing and manufacturing gearboxes.
