摘要: 多沟槽设计有助于提高轴承的散热和抗磨粒磨损性能，同时利用水流带走摩擦产生的热量，因此对沟槽参数进行优化对于提高多沟槽水润滑滑动轴承的使用寿命具有重要意义。本文以多沟槽水润滑滑动轴承为研究对象，运用ANSYS仿真流体模块进行仿真，研究槽偏角对直槽和螺旋槽水膜压力和和承载力的影响，得到流体仿真压力云图，再对数据进行后处理获得相应水膜压力和承载力曲线，对曲线图进行分析，对水润滑滑动轴承槽偏角进行优化，进而提高多沟槽水润滑滑动轴承的使用寿命。
Abstract: Multi-groove design contributes to enhancing the heat dissipation and anti-abrasive wear performance of bearings, while utilizing water flow to carry away the heat generated by friction. Therefore, optimizing groove parameters is of great significance for improving the service life of multi-groove water-lubricated sliding bearings. This paper takes the multi-groove water-lubricated sliding bearing as the research object and uses the ANSYS simulation fluid module for simulation. The influence of groove inclination angle on the water film pressure and carrying capacity of straight grooves and spiral grooves is studied. The fluid simulation pressure cloud map is obtained, and then the data is post-processed to obtain the corresponding water film pressure and carrying capacity curves. The curve diagrams are analyzed, the groove parameters are optimized, and thereby the service life of the multi-groove water-lubricated sliding bearing is improved.
