【摘要】：少齿数齿轮传动作为常规渐开线圆柱齿轮传动的重要组成和延伸,有着单级传动比大、结构紧凑等优点,近年来在电动车、风电等行业得到了一定的应用和推广。本文旨在通过研制少齿数齿轮传动的电子封闭图来解决其设计中的变位系数选择问题。本文首先以渐开线变位斜齿轮的基本理论及少齿数齿轮传动现有的研究成果为基础,对少齿数齿轮传动的齿顶变尖、有侧隙啮合、节点外啮合等问题进行了深入分析研究,并推导了相应的计算公式。其次,根据少齿数齿轮传动变位系数选择的需要,对封闭图中各种限制及质量指标曲线方程进行了推导和整理。再次,采用统一化的处理方式,将各种限制及质量指标曲线方程均转化成以变位系数为变量的形式,便于书写和编程。最后,以MATLAB为平台进行程序设计,利用该软件强大的计算和绘图功能方便的解决了电子封闭图设计中的方程求解和曲线绘制问题。最终设计出的电子封闭图不仅考虑了螺旋角,还引入等中心距线、法向侧隙及几何尺寸计算功能。经试验证明,该电子封闭图操作简单、方便,运算准确、快捷,具有较强的实用价值。
[Abstract]:A small number of teeth gear drive as conventional involute gear transmission is an important component and extension, has a single large transmission ratio, compact structure etc. in recent years, electric vehicles, wind power and other industries have been applied and extended. This paper aims to electronicsealchart through development of less teeth gear transmission to solve the variable coefficient in the design selection problem.
This paper begins with the research results of the basic theory of involute helical gear and less teeth gear on the base of current of less teeth gear pitch, a backlash, the in-depth analysis and research of node external gearing and other issues, and the calculation formula is derived.
Secondly, according to the need of the selection of the variable coefficient of the gear transmission with few teeth, various restrictions and quality indexes in the closed graph
The equation of the curve is derived and sorted. Again, by using the unified way of processing, the various constraints and quality index curve equations are transformed into the form of variable coefficient, which is convenient for writing and programming.
Finally, on the platform of MATLAB program design, the use of powerful calculation and drawing function of the software is convenient to solve the electronic seal equation and the curve in the design drawing. Electronicsealchart final design not only consider the helix angle, also introduced center distance line, calculation of normal backlash and geometry function. Experiments show that the electronic seal chart has the advantages of simple operation, convenient operation, accurate, fast, has a strong practical value.
