【摘要】 关于绝对重力仪凸轮驱动机构的国内外文献暂未给出相应的凸轮廓线的计算公式,拟采用多项式函数设计了凸轮理论廓线、工作廓线、压力角、曲率半径,并得出了一组合理的凸轮参数。更多还原

【Abstract】 The domestic and overseas papers on the cam-driven mechanism of absolute gravimeter have not provided the relative computational formulas of cam profiles. So,in this paper,the theoretical and actual cam profiles are designed by polynomial function. And then,the formulas of pressure angle and curvature radius are deduced. Finally,a set of rational cam parameters is acquired.更多还原
