用于磨削面齿轮的蜗杆砂轮修整方法研究

摘要

In order to produce face gear by a grinding worm,this paper uses the enveloping method to design the worm thread surface of grinding worm and research on a dressing method for the grinding worm. Under the investigation, a coordinate is established to describe the enveloping process of the worm,the equations describing the worm thread surface is presented. According to the Principle for design of worm,a dressing tool and a dressing method for grinding worm dressing are designed and given. The device used for dressing to perform the grinding worm of face gear.%为了实现面齿轮磨齿加工,采用包络原理对面齿轮磨削蜗杆砂轮齿形进行设计,并对蜗杆砂轮的修整方法进行研究.建立了蜗杆砂轮齿面的包络坐标系；给出了蜗杆砂轮产形面方程；推导了蜗杆砂轮齿廓的曲面方程,利用Matlab软件对蜗杆砂轮齿廓进行了仿真,根据面齿轮磨削蜗杆砂轮的齿面生成原理,给出了修整工具的齿廓形状、齿宽限制以及修整工具与蜗杆砂轮之间的运动关系,设计了一种面齿轮磨削蜗杆砂轮修整装置.
