| 目的 研究影响全自动装订机空间圆柱凸轮机构的力与运动传递性能的压力角和曲率参数。 方法 应用共轭曲面啮合理论， 推导凸轮压力角和曲率的计算公式， 基于 Matlab软件编程绘制压力角和曲率变化曲线， 得出压铆各阶段压力角最大值和诱导主曲率值， 并与许用压力角和临界曲率值作比较。 结果 在铆头上升过程中， 最大压力角为 15° ； 在压铆过程中， 压力角接近 0° ； 在铆头返回过程中， 最大压力角为 55° 。 每个点的诱导主曲率值均大于 0。 结论 升程过程最大压力角低于许用压力角 ， 可以满足要求； 压铆过程凸轮机构的力传递性能良好； 返回过程对动力要求很小， 压力角变化较大，对机器的正常工作影响很小，曲率不发生干涉。 |

| Objective To study the pressure angle and curvature parameters that affect the force and the performance of kinematics transfer of spatial cylinder cam mechanism in complete-automatic binder. Methods The theory of conjugate curved surface was applied to derive the calculation formulas of pressure angle and curvature. The curves of pressure angle and curvature were drawn based on Matlab software, the maximum values of pressure angle and the values of induced main curvature were concluded in each stage of the pressure riveting, and they were compared with the allowable pressure angle and the critical value of curvature. Results The maximal pressure angle was during the rising process of the rivet; the pressure angle was close to zero during the pressure riveting process; the maximum value of pressure angle was during the returning process of the rivet. The values of induced main curvature of each point were greater than zero. Conclusion The maximal pressure angle was lower than the allowable pressure angle during the rising process of the rivet, which could meet the requirement; the force transmission performance of cam mechanism was good during the pressure riveting process; the power demand was very small during the returning process of the rivet, the change of pressure angle was great, which had little impact on the normal operation of the machine. Curvature interference did not happen. |
