摘要
综述了目前高效、重载螺旋副研究开发的三个发展方向:减摩耐磨合金螺母、聚合物自润滑整体螺母、钢背衬复合材料螺母这三种。铜基、锌基等减摩耐磨合金螺母可以有效提高螺旋传动的工作性能,但采用切削加工难以形成有效的润滑油道;尼龙和酚醛树脂等非金属聚合物自润滑整体螺母具有良好的减摩性能,但承载能力低。钢背衬碳纤维织物/树脂复合材料螺母兼具高的承载能力和良好的减摩耐磨性能,具有良好的发展和应用前景。
There are three main developing trends in the research of screw transmission technology with high efficiency and heavy duty：nuts of wear resistant and antifriction alloys,integral nuts of self-lubricant polymers and steel backing composite screw-nuts.Though Cu and Zn based composites can improve the working performances of screw nuts,traditional machining of the nuts could not fabricate lubricant grooves on the screw surface.The integral nuts made of nylon,phenolic and other resins have good antifriction property,but their load capacities are low.Steel backing composite screw-nuts have both good antifriction property and load capacity,with great application potentiality.
