向心推力滚动轴零轴向载荷的计算,是滚动轴承计算的难点之一。自从ISO 方法在我国推行以来,这类轴承轴向载荷的计算比较繁杂,需要区别不同情况,选用公式作具体计算。例如有的文献或教材推出两组公式,也有的参考书推出四组公式,分别适用于不同的受截情况。近些年来,由于ISO 方法被引入教材,不少学校也在探索这类轴承的电算方法 Axial thrust rolling axis zero axial load calculation is one of the difficulties of rolling bearing calculation. Since the implementation of the ISO method in our country, the calculation of the axial load of such bearings is complicated and requires different situations to be selected, and the formula is used as a concrete calculation. For example, some documents or textbooks introduce two sets of formulas, and some reference books introduce four sets of formulas that apply to different situations. In recent years, due to the introduction of the ISO method teaching materials, many schools are also exploring the calculation of such bearings method
