      德国施韦因富特2019年5月31日 舍弗勒旗下所有具有X-life品质的500mm及以上孔径241系?#26800;?#24515;滚子轴承将陆续采用新的滚动体。新型桶形滚子的特点是端部采用修型处理,即在滚子端部进?#24418;?#35266;几何结构优化。这一优化使滚子在使用中更加坚固耐用。

      带非修型滚子的调心滚子轴承在使用一段时间后会因摩擦出现材料磨损,而在采用修型滚子后,磨粒磨损造成的边?#21040;?#35302;应力至少下降20%。轴?#26800;?#36816;行可靠性和使用寿命显著提升,这在矿山水泥行业应用中尤为明显。通过这一新型滚子,舍弗勒为大尺寸轴承设立了新的标准。

      滚?#26377;?#22411;具有诸多好处

      与非修型滚子相比,修型滚子的设计优势显而易见。修型滚子径向外表面采用了对数修型,在轴承工作寿命后期能够显著提升高载荷下出现端部接触应力过大的风险应?#38405;?#21147;。在常规应用条件下,由磨粒磨损造成的边?#21040;?#35302;应力发生时间大幅延后,与非修型滚子相比,当边?#21040;?#35302;应力产生时其应力至少下降20%。轴承使用寿命最多可延长15%。抗磨损能力的加强提升了设备的运行可靠性和可用性,最终使客户受益。

      目标市场:矿山水泥行业

      采用新型滚子的轴承可用于各类辊压机,比如矿山水泥行业破碎机和辊压机。这些都是高载荷及恶劣的应用环?#24120;?#24182;且存在轴承运行和维护时(如更换轴承)污染物进入的风险。异物的进入会引起滚动接触,从而导致磨损和边?#21040;?#35302;应力增加,使材料过早出?#21046;?#21171;,大幅缩短轴承使用寿命。

      X-life品质和可选配密封件

      带端部修型滚子的新款轴承保留旧款轴承全部X-life特性,其中包括经过优化的内部结构(有助提升承载能力)、得到改善的表面质量以及有效减少摩擦的浮动中档边。此外,新款轴承依然能够配备不影响设计尺寸的密封件。
