止推滑动轴承的温度场和热变形分析

通过对止推滑动轴承的传热学、摩擦学研究，建立了该轴承相应的稳态温度场和热变形的三维热分析有限元模型，并运用ANSYS分析了轴承处于热平衡状态时的温升和热变形。研究结果表明，对于井下用止推滑动轴承，由于其摩擦产生的热量很大，在地面常温下设计时应考虑到热变形对轴承间隙的影响。

Analysis of Thermal Deformation and Temperature Field for Plain Thrust Bearing

Through research on heat convection and friction of plain thrust bearing, three dimensional finite element model of stable temperature field and thermal deformation was built up. Through using ANSYS, thermal deformation and temperature of a plain thrust bearing under the status of heat equilibrium were analyzed. The research result indicates that thermal deformation influence to clearance of plain thrust beating used in well should be considered when designed it at normal temperature on the ground, because it produces high heat through friction.
