摘要
变速器是各种车辆传动系统的重要组成部分。常用的变速器有带式、链式、齿轮式等形式,均属于机械外功率分流。本文研究双斜盘同步旋转内功率分流无级变速器是辽宁省教育厅高等学校科学技术研究项目,曾获国家发明专利。目前正处于研制阶段,其理论研究尚属空白。本文应用Pro/E软件、虚拟技术、有限元等方法对该新型变速器进行了结构设计和理论分析。
     本文论述了双斜盘同步旋转内功率分流无级变速器的工作原理、结构特点。应用虚拟技术进行了从多方面研究,应用Pro/E软件对零件进行三维结构设计,在此基础上进行装配,检查各部件是否发生干涉,以检验该变速器几何参数设计的合理性。分析结果表明,其设计的几何参数是正确的。
     动平衡问题是该变速器的重要问题,也是难点问题,通过Pro/E虚拟仿真分析,确定组合部件的重心、惯性积及回转半径等,与实验测得的数据进行比较,理论分析与实测结果基本吻合,证明了理论分析计算的正确性。说明该设计应用Pro/E软件求出的复杂不规则物体的重心以及动平衡分析等结果是可信的,对生产实际具有指导作用。
     输出轴是该变速器的一个重要元件,通过Pro/E建模,基于动力学有限元基本理论,应用ANSYS/MULTIPHYSICS模块对输出轴进行结构动力学模态分析,得到五阶固有频率及振型,分析结果满足设计要求。
The transmission gearbox is an important constituent of all kinds of vehicle transmission systems. The belt type, the chain type, the tooth wheeled type and so on are popularly used now, belonging to mechanical distribution power output. The simultaneous mode internal power-distributing bencher with double-cam plate studied in this article is a university science and technology research project supported by the Educational Department of Liaoning Province, and it attained the national invention patent. So far, because it has only been in the beginning stage, and its fundamental theoretical researches are still a blank. Pro/E software, hypothesized technology, finite element method are used in this paper to carry on the structural design and the theoretical analysis to this new transmission gearbox.Firstly, the article elaborated the principle of work and the unique features of simultaneous mode internal power distributing bencher with double-cam plate. The three-dimensional structural design of the components was done by Pro/E software, and the models were assembled and built in the foundation, and then the interferences among different parts were testified and the transmission gearbox geometry parameters were made clear. From the analysis result, the design of the geometry parameter is correct.The transient equilibrium question is not only important but also difficult for this transmission gearbox. Through hypothesized simulation analysis with Pro/E, the center of gravity and moment of inertia of the assembly were fixed, and then the data obtained with Pro/E software were compared with that measured actually in the experiment. The theoretical analysis results and actual ones are basal the same. The conclusion from the analogy is that the theoretical analysis is reasonable and credible and that we can find the gravity center of irregular parts with Pro/E software to carry on the transient equilibrium analysis, a practical guidance to the actual production.The output shaft is an important part of the transmission gearbox. By constructing the mold through Pro/E and progressing the dynamics modal analysis with ANSYS/ MULTIPHYSICS, five steps natural frequencies and inspiration are obtained, so the analysis simulation results satisfy the design request.
