滚动轴承新的额定静载荷的研究

对滚动轴承现代设计中以接触应力为准则计算的滚动轴承额定静载荷进行了研究，证明许用接触应力与相对滚动体直径总的永久变形量之间存在着可以确定的到相对应的关系，并求出了它们之间的函数关系式。建立了滚动轴承额定静载荷的精确计算的数学和力学模型，经实践检验证明，新引入的以接触应力来计算和定义的额定静载荷理论与实际具有良好的吻合性。

A Study of New Rated Dead-Load Concept on Ralling Bearing

On the basis of briefly describing the development about the method of rated dead-load of rolling bearing precise calculation, rated dead-load of rolling bearing calculated by contact stress criterion is studied in modern design. The authors proved that relationship between Allowable Contact Stress and total permanent change shape of Roller diameter then their function relationship formulary are obtained, and argues that bearing design will be not conservative and rash advance when rated dead-load of rolling bearing is calculated accurately,moreover the mathematical and mechanical accurate model of rated dead-load of rolling bearing is established, which providing scientific basis for rolling bearing modern design and being very effective in practice.
