粘胶/环氧树脂基自润滑罗拉轴承的开发与制作

为克服目前细纱机罗拉轴承加油周期短、能耗大、用工多、劳动强度大等缺点,分析并制作了以环氧树脂(EP)为基体、石墨(C)为固体润滑剂、粘胶纤维(R)为增强材料的细纱机罗拉自润滑轴承,探讨了其成型工艺;并通过试验研究了其复合材料性能。试验结果表明:该种轴承具有自润滑、质量轻、强度高、摩擦性能优良、适应温度范围广、材料来源广泛、加工成型简便等优点;具有较高的承载能力和平稳的运行状态,能满足纺织工况下的使用要求,可替代尼龙支架的罗拉滚针轴承,且可长时间或终身免加油,杜绝油污纱产生,提高成纱质量,降低成本。

Development and Manufacturing of the Viscose/epoxy-based Self-lubricating Roller Bearing

In order to overcome the disadvantages of the conventional roller bearing on the current spinning frame including short lubricating intervals,big consumption of energy,high labor cost and heavy labor tensity,ananlysis is done to the self-lubricating roller bearing with Epoxy(EP) as the base,graphite(C) as the lubricating agent,viscose fiber(R) as the reinforced material for the spinning frame and the same manufactured,probing is done into the forming process,and the performance of the complex material is test proved.The test proves that the roller bearing is of self-lubrication,light in mass,high in rubostness,excellent in friction performance,wide in temperature range,abroad in material resources,easy in fabrication,the bearing is of high loading capacity and smooth operating performance,applicable for the textile production,thus a good substitution of nylon-supported roller bearing,free lubrication for a lone time or in the whole service life,consequently avoiding the oil-contaminated yarn with high quality of yarn and low cost.
