叶轮式内喷润滑剂砂轮的流场分析及实验研究

摘要/Abstract

摘要： 提出了一种叶轮式内喷润滑砂轮结构及其磨削加工的方法。基于FLUENT软件模拟分析了叶轮式内喷润滑砂轮的内腔固体颗粒流场，设计出了叶轮式内喷润滑砂轮，并通过内喷润滑砂轮磨削TC4钛合金实验，分析了内喷润滑砂轮的磨削加工性能。结果表明：叶轮式固体内喷润滑砂轮中的润滑剂在离心力的作用下，通过砂轮外缘微孔直接析出到砂轮表面，能够实现抑制钛合金黏附、降低磨削区温度和摩擦因数的目的。

关键词: 叶轮式, 内喷砂轮, 流场, 磨削温度, 摩擦因数

Abstract: An impeller wheel structure of inner spray lubrication and grinding method were described herein. The inner cavity solids flow field of the inner spray lubrication wheel was analysed by FLUENT software, the wheel structure with impeller was designed, and grinding experiments were finished through the inner spray lubrication wheel, lubrication grinding performance was analyzed during grinding TC4 alloy. The results show that: solid lubrication of inner spray wheel with impeller precipitated directly to the wheel surface under centrifugal force,throught grinding wheel peripheral pores to suppress titanium adhesion, and the grinding zone temperature and friction coefficient were reduced.

Key words: impeller, inner spray wheel；flow field；grinding temperature, friction coefficient
