船舶尾轴承倾斜加工对其润滑特性的影响研究

Research on the effect of tire bearing tilt machining on its lubrication characteristics

摩擦是船舶尾轴承在工作过程当中不可避免的。最显著的有干摩擦、半干摩擦、边界润滑和完全流体润滑。启动时,一般为干摩擦,通常采用有限元分析法。由于高速重载及较高水膜压力的原因,稳定运转时的弹性变形不容小觑。本文将在流体连续性方程及三维坐标系的基础上,建立轴承开槽、尾轴倾斜和弹流润滑轴承水膜厚度等的数学模型。

Friction is the ship tail bearing in the course of work is inevitable. The most significant are dry friction, semidry friction, boundary lubrication and complete fluid lubrication. When start-up, it usually is dry friction, and usually analyzed by finite element analysis. Due to high-speed overload and high water film pressure reasons, the stability of the elastic deformation can not be underestimated. In this paper, based on the fluid continuity equation and the three-dimensional coordinate system, the mathematic model of bearing grooving, tail shaft inclination and water film thickness is established.
