| Abstract: | The paper summarizes fault modes of slewing bearing and mechanism analysis for specific faults, and the slewing beating operation is investigated and researched as well to provide reliable reference for monitoring of crane＇s sle- wing operation state. The feasibility analysis for application of acoustic emission in crane slewing bearing is performed, with basic research thoughts, as well as discussion of signal collection and identification technology for specific faults. At last, the paper presents research prospects of acoustic emission monitoring technology of crane＇s slewing bearing. |
| Keywords: | slewing bearing fault mode mechanism analysis state monitoring acoustic emission |
