The bearing limit seat can precisely limit the bearing, preventing axial movement during operation and ensuring the stability of the bearing. The bearing housing sealing cover effectively isolates external dust and moisture, preventing them from entering the housing and contaminating the bearing and lubricating medium, thus extending the bearing's service life. A vibration sensor monitors the vibration state of the bearing housing. When the buffer rubber block, buffer rubber strip, and damping elastic element in the first buffer structure fail due to aging, causing abnormal vibration in the bearing housing, the vibration sensor can promptly trigger the limit electromagnet to be energized, allowing gas in the gas storage box to be delivered to the buffer airbag. The buffer airbag can replace the failed first buffer structure to buffer the bearing vibration, achieving a temporary replacement of the buffer structure and avoiding the need for immediate shutdown for maintenance, thus ensuring the equipment's working efficiency.
