| Abstract: |
| 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. |
