Abstract
The bucket wheel stacker-reclaimer,as a continuous,efficient,and low-energy bulk loading and unloading machine,is extensively utilized in power plants,ports,and other large raw material yards for handling coal and ore.The cantilever serves as the primary load-bearing component of this equipment,and the rotation of the bucket wheel,combined with the pitching and rotation of the cantilever,collectively accomplish the material retrieval process.However,during actual operation,the joint bearings in the pitching mechanism of the stacker-reclaimer often produce abnormal sound,which not only disrupts the normal functioning of the equipment but also poses potential safety risks.The research is designed to investigate the causes of these abnormal sounds in the joint bearings of the pitching mechanism,so as to offer corresponding solutions to ensure the safe and stable operation of the equipment.关键词
