摘要

为了充分设计具有平移滚子从动件的径向凸轮,有必要保持最大压力角不能超过经验接受值30°的约束。直接计算这个参数是困难的,通常是通过试错来减小它。到目前为止,存在的nomogram只计算凸轮与从动件之间没有偏心的凸轮的这个角度。本研究提出了两个具有此附加参数的nomogram,这允许使用所有可用变量进行更大的设计自由度。该图表适用于摆线和谐波运动曲线,并可用于它们的全曲线和半曲线。讨论了利用模态图的优点,以及合理组合现有参数求得最小最大压力角值的方法。虽然nomogram不再是工业中广泛使用的工具,但它们在教科书中仍然具有教学功能,并且可以用于工程项目的初步分析。

Nomograms for maximum pressure angles in radial cams with follower eccentricity for cycloidal and harmonic motion curves
For an adequate design of radial cams with translating roller followers, it is necessary to maintain the constraint that maximum pressure angle cannot exceed the empirically accepted value of 30°. The direct calculation of this parameter is difficult and it is usually sought to reduce it by trial and error. Nomograms that exist so far only calculated this angle for cams with no eccentricity between follower and cam. This research presents two nomograms with this additional parameter, which allows for greater design freedom using all available variables. The charts are for cycloidal and harmonic motion curves, and can be used for their full and half curves. The study discusses the advantages of using nomograms and the methods to obtain low values of maximum pressure angle by satisfactorily combining available parameters. Although nomograms are no longer a widely used tool in the industry, they still have didactic functions in textbooks and could be useful for preliminary analysis in engineering projects.
