以一汽大众混合动力汽车作为匹配对象，针对减速器部件展开了详细设计。首先分析

了减速器的作用原理，然后根据整车需求，对汽车主减速器的减速型式、齿轮传动类

型、锥齿轮的支承形式和安装方法进行了设计。然后对主减速器的齿轮和轴承展开了

具体的设计。其中，齿轮设计内容包括计算载荷的确定、齿轮基本参数计算、齿轮几

何尺寸的计算、齿轮的强度校核、齿轮材料和热处理方式选取；轴承的设计包含了转

矩的计算、齿宽中点处的圆周力计算、齿轮轴向力和径向力的计算、轴承的选型与载

荷计算。最后根据所设计的主减速器的参数结果，运用计算机辅助设计软件对所设计

的主减速器进行建模。本文的研究工作对于主减速器的性能的提高和工作可靠性的保

证具有重要的实际意义。

Design of a series hybrid electric vehicle reducer

Abstract：With the increasing market share of hybrid electric vehicles, the design of

reducers for hybrid electric vehicles has become particularly crucial. This article selects

series hybrid electric vehicle reducers as the design object, and uses FAW Volkswagen

hybrid electric vehicles as matching objects to carry out detailed design of reducer

components. Firstly, the working principle of the reducer was analyzed. Then, based on the

requirements of the entire vehicle, the reduction type, gear transmission type, support form

and installation method of the bevel gear of the car's main reducer were designed. Then

specific designs were carried out for the gears and bearings of the main reducer. Among

them, the content of gear design includes the determination of calculated load, calculation of

basic gear parameters, calculation of gear geometric dimensions, strength verification of

gears, selection of gear materials and heat treatment methods; The design of bearings

includes calculation of torque, calculation of circumferential force at the midpoint of tooth

width, calculation of axial and radial forces of gears, selection of bearings, and calculation of

loads. Finally, based on the parameter results of the designed main reducer, computer-aided

design software is used to model the designed main reducer. The research work in this article

has important practical significance for improving the performance and ensuring the

reliability of the main reducer.
