| Abstract: | Faults such as oil leakage,water incoming and grease mixing of main bearing of TB880E hard rock TBM are analyzed.Solutions such as cutterhead fixing,rockbolt locking,anti-wearing steel ring welding,lip seal position changing and HBW grease adjusting are made.In the end,the defects and faults of the main bearing of the TBM have been solved,though the working condition is poor.In this way,the boring of the TBM is guaranteed and the availability of the TBM is improved.The successful solutions can provide reference for similar situations in the future. |
