【摘要】 针对摆直动从动件空间凸轮机构性能参数缺乏有效通用分析计算模型的情况,提出一种基于统一几何特征与运动特性的空间凸轮机构压力角表达式建模方法.以圆锥凸轮机构为研究对象,推导出基于统一数学表达的摆直动从动件圆锥凸轮机构压力角解析表达式.数值计算验证了模型的正确性,为空间凸轮机构性能参数的分析计算提供了理论基础,所建立的数学模型可推广应用到其他类型凸轮机构.更多还原

【Abstract】 In view of lacking an effective universal mathematical model for analyzing performance and parameters of spatial cams with oscillatory translating follower,a new procedure of study on pressure angles of spatial cam was proposed based on unified expression of their geometrics and kinematics characters.This research taking the conical cam mechanism as the research object deduced a unified mathematical expression of pressure angels of spatial cams with oscillatory translating follower.The calculating results has proved the model’s correctness,which provides themoretical principle for nanlyzing and calculating parameters of spatial cams and this mathematical model can be applied to other types of cam mechanisms.更多还原
