摘　　要：同时考虑凸轮-滚子间许用压力角条件α1≤[α1]及连杆-摇杆间许用压力角条件α2≤[α2],对作平面运动滚子从动件盘形凸轮机构的狭义第Ⅱ类机构综合问题作进一步深入探索。通过对研究对象进行运动及受力分析,将α2≤[α2]条件转化为三力汇交点解区间,提出了三力汇交点"瞬时区间套"这一新概念,讨论了三力汇交点"瞬时区间套"的3种情形,给出了满足双许用压力角条件最紧凑机构解的求解步骤。圆满地解决了满足双许用压力角条件的作平面运动的滚子从动件盘形凸轮机构的狭义第Ⅱ类机构综合问题。Considered the cam-roller allowable pressure angle conditionα1≤[α1]and the linkage-rocker allowable pressure angle conditionα2≤[α2],the special class-Ⅱmechanisms synthesis task of disc cam mechanisms with roller follower in planar general motion is further explored.Through the kinematic and force analysis of the research object,the condition ofα2≤[α2]is transformed into the solution interval of the three force intersection,a new concepts of"instantaneous nested interval of three force intersection"is put forward.Then,three cases of"instantaneous nested interval of three force intersection"are discussed and the solution steps of the most compact mechanism satisfying the condition of double allowable pressure angles are given.Finally,the special class-Ⅱmechanisms synthesis task of disc cam mechanisms with roller follower in planar general motion is solved satisfactorily.
