Maintenance steps for elevator handrails with manufacturer's reducer

The reducer should be stable without vibration, and its main requirement is that the worm gear and the worm are well coupled. Due to the wear of the worm gear and the worm, the tooth flank clearance increases, which will cause the car to vibrate during operation. At this time, the shims of the bearing base at both ends of the worm gear shaft can be adjusted. If its worm gear shaft is an eccentric shaft structure, the bolt of the worm gear eccentric shaft bearing cover can be loosened, and the shaft can be rotated to adjust the biting lateral clearance. The range of flank clearance should be adjusted according to the regulations of each manufacturer, because it is directly related to tooth shape, lubricating oil, structure, processing technology, etc. During the elevator starting and braking process, the car has a large impact vibration during speed change and commutation operation, which may be caused by the increase of the axial clearance due to the wear of the screw thrust bearing.
