摘要
轴承中的热传导作为轴对称问题处理。利用边界元法分析轴承的稳态、均匀和连续的热传导。为克服积分困难,给出了一个轴对称导热的边界元简化公式。引入非线性边界条件,采用简单迭代计算了轴承和轴中的温度分布,计算结果表明,滚动体温度比外圈外表面温度约高10℃。
The heat conduction in rolling bearing can be treated as an axisymmet ric problem.The steady and continuous heat conduction is analyzed by using the boundary element method (BEM). To overcome the difficulty in integration, the simplified formulae in BEM of axisym metric heat conduction are given. The nonlinear boundary condition is introduced and a simple iteration is adopted for calculating the tempe rature distribution in bearing and shaft. The result shows the tempe-rature of rolling elements is 10℃ higher than that of the outer surfa ce of outer ring approximately.
