Technical Problem

其中,贯穿式超精研是最具有代表性的也是目前滚子滚动面超精加工应用最为广泛的方法,此加工方法中,滚子以逐个连续的形式依次被加工,该方法中滚子与导辊之间的纯滚动发生在接触线上某一点,其余位置始终处于相对滑动,这使得导辊剧烈磨损,设备精度急剧降低,严重影响单个滚子精度和多个滚子的精度一致性

Benefits of technology

[0018]滚子与内环、外环间的接触关系和相对运动关系在滚子圆柱部分任意横截面内均相同,滚子F与内环、外环接触线上任意两点间不存在速度差,不会产生“锥度”。滚子与内环、外环接触线上任一点均能实现纯滚动,纯滚动以“线”的形式存在。通过主动控制滚子在内环、外环间进行纯滚动,结合研磨介质的微切削作用实现滚子研磨与超精加工,兼顾滚子纯滚动和多样本直接比较,遵循材料等概率去除原理和尺寸选择原则,可有效提升滚子的批量精度一致性。
