滚动轴承寿命计算中动载荷概念释疑

The Explanation of Dynamic Load in the Evaluating for the Life of Ball Bearing

"当量动载荷"和"额定动载荷"是在滚动轴承的寿命计算中两个重要的基本概念,但对其概念内涵的界定,多数资料过于概括,容易引起人们的误解。文章的写作目的,就是要理清"当量动载荷"和"额定动载荷"的概念内涵和它们之间的关系。

Mechanical Engineering Department, Lanzhou Petrochemical College of Vocational Technology ＂Equivalent dynamic load＂ and ＂rating dynamic load＂ are both important basic notions in the evaluating for the life of ball bearing. But there is no clearance to define both the notions. The motive to write the essay is to make clear both the notions and the relationship of both.
