全液压钻机导向套的改进

Improvement of Guide Sleeve of Hydraulic Drill

为了克服现有钻机导向套结构复杂、不易维修的缺点,结合导向套现场使用情况,利用滑动摩擦原理,设计出一种结构简单、便于现场维修的新导向套。介绍了新型导向套的结构特点及其主要零件的设计要点。

To overcome shortages of existing guide sleeve, such as complicated structure and hard to repair, combined with using status of guide sleeve, a new guide sleeve is designed with principle of sliding friction. It is simpler in structure and more convenient to repair in mine. The structure features and keypoints to design the main parts are introduced.
