| 摘 要： | 针对不同类型的圆柱凸轮机构的空间运动特点,建立啮合过程中滚子与凸轮的空间相对运动关系,研究了在Pro/E平台上利用关系式对圆柱凸轮建模的方法,对移动从动件圆柱凸轮机构采用Pro/E可变截面扫描工具建模,对摆动从动件圆柱凸轮机构使用方程式工具建模。通过在凸轮毛坯模型上建立理论轮廓曲面,并对其法向加厚、实体切除操作得到工作轮廓曲面,完成了圆柱凸轮的精确建模,其建模过程清晰、简练。建模时均使用参数表达,能够实现参数化和系列化设计,以提高效率。

| Abstract: | Aimed at the space motion characteristics of different types cylindrical cam,relative movement between roller and cam during engagement process was set up,and some modeling methods for cylindrical cam were studied by using Pro/E relations,"Variable section sweep"tool was applied to modeling for cylindrical cam with translating follower,and"equation"tool was used to modeling for oscillating follower cylindrical cam.Theoretical profiles were built up on the blank model of cylindrical cam and working profiles were obtained by normal thickening of the theoretical profiles and solid cutting operation.Therefore,the accurate models of cylindrical cam were finished,which modeling process is simple and concise.High-efficiency is realized by the parameterized design and seriate design of the cylindrical cams with the parameter as expression during modeling. |
