纯电动汽车二级齿轮减速器设计

摘要：二级齿轮减速器是全电动汽车驱动的关键部件，其结构与性能的优化是提

升其综合性能的关键。为此，本文开展纯电动车辆二级传动系统的结构与性能的研究，

旨在提高纯电动汽车的传动效率和运行平稳性。首先，研究将对纯电动汽车的传动系

统进行分析，深入了解其工作原理和特点。通过对各种纯电动汽车的齿轮传动系统进

行对比研究，找出不足之处，并探讨如何改进。其次，研究将对二级齿轮减速器进行

详细的设计。齿轮减速器是将电动机的高速旋转转换为车轮的低速旋转的重要装置，

其设计的合理与否直接影响到整个传动系统的效率和性能。因此，本文将通过系统的

考虑各种因素，如齿轮的模数、齿数、齿距、啮合角等，来确定最佳设计参数。最后，

将对所设计的二级齿轮减速器的关键部件，运用有限元方法进行分析，旨在保证所设

计的二级减速器可以满足工作强度要求，在保证实现减速功能的基础上，提高工作可

靠性，延长使用寿命，保证整车的安全的行驶。针对在分析过程中存在的风险项，提

出改进和优化措施，以保证二级齿轮减速器关键部件的强度满足工作强度要求。

Design of Secondary Gear Reducer for Pure Electric Vehicles

Abstract：The secondary gear reducer is a key component in the drive of all electric

vehicles, and the optimization of its structure and performance is the key to improving its

comprehensive performance. Therefore, this article conducts research on the structure and

performance of the secondary transmission system of pure electric vehicles, aiming to

improve the transmission efficiency and operational stability of pure electric vehicles.

Firstly, the study will analyze the transmission system of pure electric vehicles to gain a

deeper understanding of their working principles and characteristics. By comparing and

studying the gear transmission systems of various pure electric vehicles, identify the

shortcomings and explore how to improve them. Secondly, the study will provide a detailed

design of the two-stage gear reducer. A gear reducer is an important device that converts the

high-speed rotation of an electric motor into the low-speed rotation of a wheel. The

rationality of its design directly affects the efficiency and performance of the entire

transmission system. Therefore, this article will determine the optimal design parameters by

systematically considering various factors, such as the modulus, number of teeth, tooth pitch,

meshing angle, etc. of the gear. Finally, the key components of the designed secondary gear

reducer will be analyzed using finite element method, aiming to ensure that the designed

secondary reducer can meet the requirements of working strength, improve working

reliability, extend service life, and ensure safe driving of the entire vehicle while ensuring

the implementation of deceleration function. Propose improvement and optimization

measures for the risk items that exist during the analysis process to ensure that the strength

of key components of the secondary gear reducer meets the working strength requirements.

Keywords: Secondary gear reducer; Bevel gears; Axis; Bearings; finite element analysis
