港口起重机械回转轴承更换技术

Replacement Technology of Slewing Ring of Port Crane

对于传统码头作业的门机或散货起重机械,回转轴承是一个很特殊的部件,一旦有异响或有其他异常(如润滑废油中出现颗粒物),会造成不可逆转的损失。改进润滑可以适当延长它的使用时间,但如果项目选择修复(修磨滚道更换滚珠等),一般需要拆卸回转轴承。这是一个复杂危险的工作,且拆装费用昂贵。因此,文章重点研究港口起重机械回转轴承更换技术,以降低部分费用。

For the traditional terminal crane machine or bulk mechanic machine’s operation,twisting bearing is a special part.Once heard some abnormal sound or other abnormity(such as lubrication waste oil appears particulate matter),it causes irreversible damage.Improve lubrication can appropriately prolong the usage.But if it can be repaired in the project,such as grinding raceway or replacing ball bearing,the project repair normally should need dismantle the bearing.It’s a complicated and dangerous work,also the expense is expensive.Anyway,the replacing technology of the new bearing can reduce some cost.
