滚动轴承.陶瓷滚动元件混合轴承额定载荷.第2部分:额定静负荷

[中文适用范围]： 本文件规定了混合轴承（其轴承圈由高优质硬化滚动轴承钢制成，滚动元件全部由符合当代常用材料和制造质量的氮化硅（Si3N4）制成）的静态载荷额定值的计算方法。对于球，适用ISO 26602和ISO 3290-2。对于滚子，适用ISO 12297-2，并类比适用ISO 26602。对于使用混合轴承的应用，应遵守表1和表2中的静态安全系数S0的指导值。 [外文原描述]： ISO 20056-2:2017 specifies methods of calculating the static load ratings for hybrid bearings with bearing rings made of contemporary, commonly used, high quality hardened bearing steel, in accordance with good manufacturing practice, and a full set of rolling elements made of silicon nitride (Si3N4) in contemporary, commonly used material and manufacturing quality. For balls, ISO 26602,[4] together with ISO 3290‑2,[1] is applicable. For rollers, ISO 12297‑2[2] is applicable, and ISO 26602[4] is applicable in an analogous way. For applications where hybrid bearings are used, guideline values of the static safety factor, S0, according to Table 1 and Table 2 are observed.
