本文介绍的齿条齿轮-连杆机构由曲柄、齿条及齿轮等组成(图1),该机构可用以实现预定三位置的函数关系。作者采用运动综合的复数法以及基础代数与几何方法来设计与分析这种机构。在曲柄的某种角速度与角加速度值的情况下设计者能够指定曲柄和齿轮所需的回转数。这种机构的综合方法将提供满足若干预定条件的很多设计方案,设计者可以从中选择一个合适的设计方案供某种专门用途。机构分析的程序能列表输出角位移、角速度、角加速度与齿条系数K(定义见下述)及其一阶、二阶导数。
This article describes the rack and pinion - link mechanism by the crank, rack and gear and other components (Figure 1), the mechanism can be used to achieve a predetermined three-position function. The authors use the complex method of motion synthesis and basic algebra and geometry to design and analyze this mechanism. With some angular and angular acceleration of the crank the designer can specify the number of revolutions required for the crank and gear. A comprehensive approach to such an organization will provide many design options that satisfy a number of predefined conditions from which designers can choose a suitable design for a specific purpose. The program list of the mechanism analysis outputs the angular displacement, angular velocity, angular acceleration and rack factor K (defined below) and their first and second derivatives.
