摘　　要：以负半径滚子从动件盘形凸轮机构为研究对象,通过建立通用运动学条件模型,得到了关于该类直动、摆动从动件凸轮机构滚子作纯滚动的运动学条件。通过分别对从动件内、外圈进行力学分析,得到了关于直动、摆动负半径滚子从动件凸轮机构更具真实结构特点的滚子作纯滚动的力学条件。By taking disc cam mechanisms with negative radius follower as the objective,and by establishing the general kinematics condition model,the kinematics condition for the roller of this type of translating and oscillating follower cam mechanisms to carry out pure rolling was obtained.By carrying out force analysis on inner ring and outer ring of these mechanisms respectively,the dynamics conditions for the roller carrying pure rolling that have much more real structure characteristics for translating or oscillating follower cam mechanisms with negative radius was achieved.
