本文根据国际标准化组织(ISO)推荐的最新方法,对变工况下滚动轴承的寿命计算进行了分析、研究,提出了求取关健性的平均当量动负荷的计算法及图解法;以最为典型的柴油机滚动主轴承的寿命计算为例,给出了变工况下动载滚动轴承寿命计算的步骤及电算流程图。该计算方法将收入作者参加编写的“滚动轴承手册”及“船用柴油机设计手册”内。
Based on the latest method recommended by the International Organization for Standardization (ISO), this paper analyzes and studies the life calculation of rolling bearing under variable working conditions, and puts forward the calculation method and graphical method for calculating the average dynamic equivalent dynamic load. The most typical method Of diesel rolling main bearing life calculation as an example, given the variable load bearing dynamic life calculation steps and computer flow chart. The calculation method will be included in the author’s book “Rolling Bearings Manual” and “Marine Diesel Design Manual.”
