The invention relates to the technical field of aviation gas turbine engines, and discloses a turbofan engine turbine structure with built-in motor power extraction and a turbofan engine. The exhaust support and the low-pressure turbine rotor are coaxially mounted and rotationally connected; the engine tail cone is coaxially fixed on the exhaust support; the power extraction motor is arranged in an engine tail cone and is coaxially fixed on the exhaust support, and a rotor shaft of the power extraction motor is connected with a low-pressure turbine rotor through a transmission shaft; the inlet end of the motor lubricating oil pipeline is communicated with the lubricating oil cooling circulation system, the outlet end of the motor lubricating oil pipeline is communicated with the power extraction motor, and a cable of the power extraction motor penetrates through the motor lubricating oil pipeline. The motor is arranged in the turbine, the motor rotor is directly connected with the low-pressure turbine rotor, a complex transmission device does not need to be arranged, the structure is simpler, and the research, development and manufacturing cost is reduced. And the motor cable is inserted into the lubricating oil pipeline, and the electric wire is cooled through lubricating oil, so that the influence of high-temperature fuel gas is reduced, and reliable work of the electric wire is ensured.

    本发明涉及航空燃气涡轮发动机技术领域,公开了一种内置电机功率提取的涡扇发动机涡轮结构及涡扇发动机,包括:低压涡轮转子;排气支承,与低压涡轮转子同轴安装且转动连接;发动机尾锥,同轴固定于排气支承上;功率提取电机,置于发动机尾锥内,且同轴固定于排气支承上,其转子轴与低压涡轮转子通过传动轴相连;电机滑油管路,进口端连通滑油冷却循环系统、出口端连通功率提取电机,且功率提取电机的线缆贯穿于电机滑油管路中。通过将电机置于涡轮内部,并将电机转子与低压涡轮转子直接相连,无需设置复杂传动装置,结构更加简洁,降低研发制造成本。且电机线缆插入滑油管路中,通过滑油对电线进行冷却,减少高温燃气的影响,保证电线可靠工作。
