| 摘 要： | 用短轴承理论近似分析有限长轴承，只适用于宽径比比较小的情况，在短轴承理论基础上的结合Ｇａｌｅｒｋｉｎ方法首次给出了有限长轴承非稳态油膜力的近似公式，既保留了由短轴承理论所给出公式的简单性，又使其在很大宽径比范围内具有很高的精度，以满足工程的需要，最后进行了实例计算。

| Abstract: | The paper solves Reynolds equation of finite journal bearing by improving short bearing theory and gets pressure distribution by Galerkin method. The general approximate formula for calculating the dynamic loading of finite journal bearings is first reached. The results based on the formula are conforming to numerical result. |
