大直径摆线轮的双端面磨床设计研究

Design of Double Face Grinding Machine for Large Diameter Cycloid

为了使得大直径摆线轮在针轮中无卡顿转动,以及实现大直径摆线轮的高精度加工和保持性,需要对大直径摆线轮的加工方法进行研究。目前的大直径摆线轮加工方法,主要通过改变大直径摆线形成参数以及转动大直径摆线轮和调整砂轮位置来实现其修形。当前方法由于受到加工设备磨齿机性能影响,其生产效率和加工精度均不理想。为了提高生产效率,改善加工工艺,提出一种大直径摆线轮的双端面磨床设计方法,首先计算大直径摆线轮的标准齿形方程;然后将移距修正法、等距修正法和转角修正法相结合,对大直径摆线轮的齿廓进行修正;最后在双端面磨床的平行度分析基础上,对双端面磨床的最大磨削余量进行理论计算,在对大直径摆线轮进行磨削时控制双端面磨床砂轮开口量,提高和保持大直径摆线轮的加工精度,改善加工工艺。实验结果证明,本文方法能够提高大直径摆线轮的加工精度且加工精度保持性较好,使用寿命较长。
