摘　　要：通过提出往行程、返行程等新概念,澄清了往(返)行程与推(回)程之间的区别,给出了负半径滚子直动、摆动从动件盘形凸轮机构的共计6种机构结构型式,应用"虚位移方法"推导得到了相应的一系列压力角公式,为日后考虑压力角条件的机构尺寸综合奠定了理论基础.Putting forward new concepts forward-travel and back-travel, the difference of rise-travel and forward-travel （back-travel and return travel） was clarified. Six kinds of cams with negative-radius roller translation or oscillating follower were received. The expression of pressure angle of these cam mechanisms were obtained by virtual displacement method. These works will be helpful to the analysis and synthesis of these can mechanisms by pressure angle later.
