| 中文摘要: |
| 介绍油封弹簧径向力（P）的一种计算方法，并进行试验验证。选取8种常用规格（0.30×1.6，0.36×2.0，0.45×2.5，0.50×3.0，0.60×3.5，0.80×4.0，1.00×5.0和1.20×7.0）的油封弹簧，在不同轴径（50～1 600 mm）和不同伸长率（＜10%）下分别计算P；依据P的推荐取值，得出适合规格油封弹簧轴径的适用范围，为油封弹簧的选型和设计提供参考。 |

| A calculation method of the radial force of oil seal spring（P） was introduced，and the verification test was carried out. 8 kinds of common oil seal springs（0. 30×1. 6，0. 36×2. 0，0. 45×2. 5，0. 50×3. 0，0. 60×3. 5，0. 80×4. 0，1. 00×5. 0 and 1. 20×7. 0 ） were selected，and P values were calculated under different shaft diameters（50～1 600 mm） and different elongation（＜10%）. According to the recommended P values，the applicable ranges of the shaft diameter of suitable specifications of oil seal spring were obtained，and a reference for the selection and design of the oil seal spring was provided. |
