摘　　要：大型直联摩擦式提升机的轴承作为提升机关键零部件,其选型设计及寿命直接关系到提升机设计及后续能否正常运转。传动侧选用的双列调心滚子轴承,在设计选型计算时,传统方法仅能获得径向力,往往不考虑其轴向力。通过测试得到了轴向力,并与传统计算值做了对比,得出与传统计算方法不考虑轴向力的差异。提出了提升机轴承寿命修正系数计算方法,并得出提升机轴承修正额定寿命与基本额定寿命的关系。As a key component of the hoist,the selection,design,and service life of the large direct-connected friction hoist bearing were directly related to the design and the subsequent normal operation of the hoist.The double row self-aligning roller bearing selected for the transmission side could only obtain the radial force through traditional methods in design and selection calculation,often without considering its axial force.The axial force was obtained through testing and compared with traditional calculation values,resulting in differences from traditional calculation methods that did not consider the axial force.Then,a calculation method for the correction coefficient of the service life for hoist bearings was proposed,and the relationship between the corrected rated life and the basic rated life of hoist bearings was calculated.
