摘要差速器在割草机实现平稳转弯以及零半径转弯过程中起到了非常重要的作用，因此，零转弯半径割草机差速器的设计是该割草机设计的重要组成部分之一。本次课题所要设计的就是安装在驱动桥的两个左右半轴之间的差速器，并且对差速器的发展现状，工作原理和种类等等做了简单的介绍。差速器的内部结构并不复杂，但内部的传动机构涉及到了多种非标准件如齿轮结构和标准零件的设计计算，这就使差速器的设计显得相对比较复杂，按照传统的方法进行试验研究难度较大，这就要求我们采用新的研究方法来研究和分析差速器的设计。56689

本文通过运用PROE绘图软件，绘制差速器三维实体模型，然后运用ADAMS分析软件对差速器进行运动仿真，并且验证差速器运动是否存在运动干涉。在建立差速器三维模型和绘制二维图的过程，我的学习能力也得到了很大的提高。

Abstract:The differential in the mower to achieve a smooth turning and zero radius turn plays a very important role, therefore, the design of zero turning radius mowers differential is one of the most important parts of the mower design. This topic is to design the drive axle is installed in the two left and right half axis between the differential, and the current development of differential, working principle and types and so on to do a simple introduction. The internal structure of differential is not complicated, but the internal driving device relates to the design of various non-standard parts such as gear structure and standard parts of the design calculation, which makes the differential is relatively complex, according to the traditional method of experiment design is difficult, this requires us to study and analyze the differential with new method the.

In this paper, through the use of PROE drawing software, drawing the differential three-dimensional entity model, then using ADAMS analysis software to carry on the movement simulation to verify the differential motion differential, and the existence of motion interference. In the process of establishing three-dimensional model of differential and two-dimensional graph drawing, my learning ability has been greatly improved.
