| 为支撑宽体客机发动机总体方案论证，以齿轮驱动涡扇发动机5路分流星型齿轮减速器为研究对象，分析了星型齿轮减速器所受重力载荷及人字齿轮啮合时产生的扭矩对传扭支架受力的影响。在考虑重力载荷的基础上，根据啮合扭矩对星型齿轮减速器安装角度进行了计算并使用有限元软件对结果进行了验证。结果表明：当齿轮啮合扭矩为顺航向顺时针时，应使任意支架连杆处于3点钟位置；当齿轮啮合扭矩为顺航向逆时针时，应使任意支架连杆处于9点钟位置。 |
| 英文摘要: |
| In order to support the scheme demonstration of a wide-body jetliner engine, the influences of gravity load and herringbone gears meshing torque to the carrier have been studied with regard to a star gearbox of five planets in a geared turbofan. Considering the gravity load of the star gearbox and the meshing torque of gears, the mounting angle of the star gearbox has been calculated and verified by finite element software. The results show that one limb should be at the 3 o'clock while meshing torque is clockwise along the aircraft body axis, and one limb should be at the 9 o'clock position while meshing torque is anticlockwise along the aircraft body axis. |
