摘　　要：以NUTR类滚轮轴承为例,介绍了其主参数及外圈截面参数,分析了外圈的受力情况,得到外圈最大边缘应力所在位置及其计算方法,并通过实例分析得到:最大允许动载荷是根据最大允许边缘应力计算,且推导出滚轮轴承最大允许动载荷的计算方法。The main parameters and sectional parameters are introduced for outer rings of NUTR type track roller bearings.The load of outer rings is analyzed,and the position of maximum edge stress of outer rings and its calculation method are obtained.The case analysis shows that the calculation of maximum allowable dynamic load is based on maximum allowable edge stress.The calculation method is deduced for maximum allowable dynamic load of track roller bearings.

关 键 词：滚轮轴承 主参数:边缘应力 最大允许动载荷
