| Abstract: |
| 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. |
