Heat generation has notable influence on bearing’s performance. In order to analyze the influence of cooling conditions on the cooling effect, the model of forced cooling system for a rolling bearing was established, the temperature ifeld of a certain type of bearing under different cooling conditions was qualitatively analyzed by the model.%轴承发热对其性能有着显著影响。为了分析冷却条件对冷却效果的影响，对滚动轴承的强制散热系统进行了建模，并利用该模型对某型号轴承在不同散热条件下的温度场进行定性分析。
