| 中文摘要: |
| 研究风机轴承用夹布油封原材料的选择以及在线安装夹布油封的结构设计方法。结果表明：密封材料在热带可选氟橡胶，在寒带宜选耐低温的丁腈橡胶（NBR），海上则选用氢化丁腈橡胶较为适宜；NBR夹布橡胶硫化前吸水率可达4%，硫化后吸水率仍在0.5%～1%之间；NBR夹棉布橡胶的线膨胀系数在5×10-6～8×10-6 ℃-1之间。 |
| 英文摘要: |
| The raw material selection of fabric-rubber oil seal for wind turbine bearings and structure design method of on-line installation of fabric-rubber oil seal were studied.The results showed that，FKM was suitable as sealing material in torrid zone，cold-resistant NBR in frigid zone，and HNBR on the sea.The water absorption of fabric-NBR was 4% before curing，and in the range from 0.5% to 1% after curing.The linear expansion coefficient of cotton canvas-NBR composite was from 5×10-6 ℃-1 to 8×10-6 ℃-1. |
