综采三机链轮环内端面密封槽车削修复技术研究

Repair technology of inner face seal groove of three machine sprocket ring in fully mechanized coal mining

本文重点研究了链轮环端面密封槽的车削修复工艺。制定了链轮环端面密封槽车削修复装夹方案并设计制作了装夹工装;制定了车削修复工艺,选取了科学合理的车削刀具及车削用量三要素;通过三坐标检测及装配试运行,链轮环端面密封槽的修复达到了修复要求,设备在井下进行了工业性实验,工件使用寿命显著增加。

This paper lays emphasis on the technique of turning recovery of end face seal groove of sprocket.It makes a turning recovery and clamping scheme,designs and produces clamping frock,determines the turning recovery technique,and selects scientific turning tools and three elements for turning parameters.Through three-dimensional detection and pilot run of assembly,the recovery of end face seal groove of sprocket meets the requirement.Besides,the industrial experiment under the shaft shows the service life of work piece significantly increases.
