| description | The lubrication model of the slope-platform pad thrust bearing with different structural parameters are built,the effects of the slope angle,oil film thickness and angular speed on bearing temperature field are studied. And the effects of the speed on the load capacity of the bearing is also analyzed under conjugate heat transfer circumstance,which provide the theoretical guidance for design and use of thrust bearing. The results show that the maximum temperature of the bearing pad appear in the circumferential outlet and near the outer diameter side,which decreases with the increase of the slope angle. When the other conditions are constant,the larger the thickness of the oil film is,the lower the temperature rise of bearing,and the film thickness does not affect the temperature field distribution of the bearing. The shear stress and bearing temperature are increased with the increase of speed. There is no longer a linear relationship between the axial bearing capacity and speed when considering the coupling heat transfer. |
