摘要：通过对圆柱滚子轴承各个滚子的受力分析,探讨了不同载荷和转速下发热量的计算方法,得出了较为精确的轴承发热量计算公式。计算了不同条件下各个滚子的发热量。并以此为边界条件,应用有限元法计算了轴承系统的温度场分布,得出了合理的温度场分布图。。证明此公式对圆柱滚子轴承发热量和温度场的计算具有可行性。
By means of the analysis of forces supplying on every roller in cylindrical roller bearing, the feasible method to compute the thermal value under different loads and velocity is investigated. The formula used to calculate accurately thermal value are obtained. And with this method the thermal value of every roller of a specific bearing is calculated. Then the thermal value taken as boundary condition is used to simulate the distribution of temperature field of the bearing system. A fact is discovered that the distribution of temperature field of the bearing coincides primarily with the reality. It is confirmed that the established method is viable to compute the thermal value and temperature field of cylindrical roller bearing.
