Description

圆锥滚子轴承用润滑脂组合物
技术领域
本发明涉及润滑脂组合物和使用其的圆锥滚子轴承。
背景技术
用作圆锥滚子轴承等滚动轴承中使用的润滑剂的润滑脂组合物一般由增稠剂、基油和添加剂三者构成。例如，圆锥滚子轴承作为支撑以铁路车辆、汽车为代表的车辆的车轴的轴承被广泛使用。作为一例，作为支撑汽车的车轴的滚动轴承，如非专利文献1、非专利文献2中记载的那样，转动体有使用珠子的球型轮毂单元、使用圆锥滚子的锥型轮毂单元等，在以SUV、小型卡车为代表的大型车、商用卡车等车体质量重的汽车中，为了支撑更大的负荷，应用了使用圆锥滚子的锥型轮毂单元、圆锥滚子轴承。但在使用锥型轮毂单元、圆锥滚子轴承的情况下，虽然支撑了更大的负荷，但与球型轮毂单元相比，以滚柱端面与凸缘部、滚柱与保持器的润滑为代表的滑动润滑的位置多，磨耗、剥离会成为问题。
此外，如非专利文献3中记载的那样，为了提高汽车的燃油效率，对于变速器等中使用的圆锥滚子轴承，低扭矩化的要求也在不断提高，与球型轴承相比，锥型轴承的轴承扭矩高，低扭矩化成为课题。
进一步，伴随使用环境的扩大，使用温度也扩展至更低的温度，低温环境下货车输送时等发生的微动磨耗、低温起动性等与润滑剂的低温流动性相关的低温性的要求也在不断提高。
因此，作为在使用圆锥滚子的锥型轮毂单元、圆锥滚子轴承中适用的润滑脂组合物，有必要提高耐磨耗性、低扭矩性、低温性。
作为考虑了使用圆锥滚子的锥型轮毂单元、圆锥滚子轴承的耐久性、耐微动磨损性的润滑脂组合物，提出了增稠剂中使用芳香族二脲、基油中使用矿物油和/或合成烃油、添加剂中使用有机钼化合物的润滑脂(专利文献1)，但并未提及低扭矩性、低温性。此外，作为抑制低温环境下的微动磨耗的润滑脂组合物，提出了增稠剂中使用脂环式脂肪族二脲、基油中使用矿物油、添加剂使用磷酸胺的润滑脂组合物(专利文献2)，但没有关于低温起动性的记载，此外，关于低温环境下的微动磨耗，假设的也是转动体为珠子的情况，而不是圆锥滚子。
如上所述，对于在使用圆锥滚子的锥型轮毂单元、圆锥滚子轴承中适用的润滑脂组合物，结合近年来使用环境的扩展，要求耐磨耗性、低扭矩性、低温性。
