在无心磨床或无心支承轴承套圈磨床上越来越广泛地要求采用大余量磨削及强力磨削。在实际磨削中发现,当磨削用量超过某一数值时出现导轮倒拖现象,即导轮反过来被工件带动旋转,使导轮电机处于卸荷或发电状态,有时甚至造成事故。近几年来我厂针对无心磨削时出现的倒拖问题,从电气方面采取了一些措施,效果较好。下面就导轮倒拖的原因及其解决办法作一介绍。 In the centerless grinder or centerless bearing bearing ring grinder more and more require the use of large grinding and grinding force. Found in the actual grinding, when the amount of grinding exceeds a certain value when the guide wheel drag phenomenon, which in turn guide wheel driven by the workpiece rotation, the guide wheel motor in the unloading or power generation, and sometimes even cause accidents. In recent years, my factory for unwinding grind drag problems arise from the electrical aspects to take some measures, the effect is better. The following reasons for the guide pulley and its solution to make an introduction.
