摘要

摘要: 提出以端面铣刀代替球面铣刀端铣摆线齿轮齿廓的加工方法。利用前倾角和侧倾角分别解决端铣刀局部干涉与刀杆碰撞干涉问题的方法，得出无干涉加工摆线齿轮刀轴前倾角的计算公式。建立端铣摆线齿轮的几何模型和五轴数控仿真模型，获得其无干涉刀具轨迹。利用五轴联动立式加工中心实现摆线齿轮的高速端铣加工，得到精加工的摆线齿轮样件，并对精加工的摆线齿轮齿廓的精度和表面粗糙度进行了测量和分析。该摆线齿轮样件的最大偏差值为0.051 mm，最小偏差值为-0.085 0 mm，所测齿廓表面粗糙度的平均值Ra为0.504 6 μm。研究结果表明：高速端铣摆线齿轮的加工方法可以达到磨削摆线齿轮的加工精度，实现了摆线齿轮加工的“以铣代磨”。

Abstract: The machining method of face milling the tooth profile of cycloidal gear with face mill instead of ball end mill is proposed. A method is proposed to solve local interference and collision interference of face mill by using the tool rake angle and side inclination angle. The calculation formula of the tool rake angle for machining cycloidal gear without interference is obtained. The face milling process of the cycloidal gear under high speed is realized by using five axis linkage vertical machining center and the cycloid gear prototype after finishing is obtained. The machining accuracy and surface roughness of tooth profile of the cycloid gear after finishing are measured and analyzed. The maximum deviation of the cycloid gear prototype is 0.051 mm, the smallest deviation is -0.085 0 mm. The average surface roughness Ra of the tooth profile is 0.504 6 μm. The results show that the method of face milling cycloidal gear under high speed can achieve the machining accuracy of the grinding cycloidal gear so as to realize the goal of "milling instead of grinding" in machining cycloidal gear.
