| 中文摘要: |
| 在油封胶料中添加钴元素，进行油封台架试验，测量并对比试验前后油封的径向力，并通过油液检测获得油封不同磨损状态下油液中钴元素浓度，建立油液中钴元素浓度与油封磨损质量的关系曲线。结果表明：台架试验前后油封径向力均随着时间的延长而减小，试验后由于油封唇部磨损导致油封径向力减幅较大；油封磨损质量与油液中钴元素浓度几乎呈线性关系，且试验开始时油封磨损速度较快，随着时间的延长磨损速度逐渐减小。 |
| 英文摘要: |
| Cobalt element was added to the oil seal compound，and the oil seal bench test was carried out. The radial force of the oil seal before and after the test was measured and compared. The concentration of cobalt element in the oil under different wear conditions was obtained，and the relationship curve between
the concentration of cobalt element in the oil and the wear weight of the oil seal was established. The results showed that the radial force of the oil seal decreased with time，and it decreased greatly after the bench test due to the wear of the seal lip. The wear weight of the oil seal was almost linear with the concentration of
cobalt element in the oil，and the wear speed of the oil seal was faster at the beginning of the test，and then decreased gradually. |
