摘　　要：中介轴承做为双转子航空发动机的低压转子和高压转子之间连接的关键零件,其运行状态直接影响发动机的工作性能和飞机的飞行安全。中介轴承的均载修形研究对于提高航空发动机的工作寿命和可靠性具有重要意义。研究了弹性流体润滑条件下,某对转双转子发动机的中介轴承的最佳修形方式。采用切片法,计算了直线圆柱滚子轴承、修正线修形圆柱滚子轴承、全凸修形圆柱滚子轴承以及对数修形圆柱滚子轴承在受径向载荷和倾覆弯矩联合作用时轴承的受力和歪斜情况,通过对比不同修形下滚子的最大载荷数值,得出中介轴承应采取的最佳修形方式。为某型双转子发动机中介轴承设计提供了参考。As the most important part of aircraft engine ,the intershaft support roller bearing decide the work situation of the aircraft engine and the flight safety of airplane .In order to extend the life of aircraft engine and increase dependability of plane ,the study of equilibrating load crowned of intershaft support roller bearing have very important sense. It we used ＇slicing method＇ and studied the four crowned methods of the intershafi support roller bearing when it was suffering the radial force and flexural torque in EHL and found the best crowned.
