摘　　要：凸轮廓线的曲率半径直接决定了凸轮的加工与制造 ,也决定了柱塞运动规律的准确性和恒流量往复泵动力端的可靠性。文章主要对恒流量往复泵中凸轮理论廓线与实际廓线的曲率半径进行了分析 ,为恒流量往复泵中特殊廓线凸轮的设计、制造奠定了理论基础。通过分析可知 ,理论廓线曲率半径 ρ、实际廓线曲率半径 ρC 和滚子半径r满足这样条件 :ρ >ρC≥r >0。The curvature radius of cam outline directly determines on the manufacture of cam, and the accuracy of motion law of the plunge and the reliability of the power end of constant flow reciprocating pump. In this paper, the author mainly has analysed the curvature radius of theoretical and actual cam outline, which establishes the theoretical foundation for the design and manufacture of the cam with special outline. Through analysis, we know that the condition among the curvature radius ρ of theoretical outline and the curvature radius ρc of actual outline and the radius r of the roller must be met: ρ>ρ C≥r>0.
