摘要
首先,分析滚动轴承在风电传动系统中应用的局限性,探讨滑动轴承"以滑代滚"的可行性.然后,从风电机组用滑动轴承结构设计、轴承材料、性能分析及优化、试验测试及应用4个关键环节,综述滑动轴承风电应用的现有技术手段和面临的困难.最后,对风电机组滑动轴承的材料改性、一体化设计、延寿技术发展趋势做出展望.
Abstract
Firstly,this paper analyzes the limitations of rolling bearings application in wind turbine transmission systems,and the feasibility of journal bearings"replace rolling with sliding"is explored.Then,from the four key links of wind turbine journal bearing structure design,bearing material,performance analysis and optimization,experimental testing and application,the existing technical means and difficulties faced by journal bearing application in wind turbine are reviewed.Finally,the development trend of material modification,integrated design,and life extension technology of wind turbine journal bearings are prospected.
