Bearing oil mist lubricating and cooling structure for supplying oil to axis

The invention discloses a bearing oil mist lubricating and cooling structure for axis oil supply, and relates to the technical field of aero-engines. The device is arranged in an aero-engine, and the aero-engine comprises a rotor shaft, a worm gear rotor, a combustor, a hot end bearing and a sealing ring. An oil cavity is formed in the rotor shaft, an annular channel is formed between the sealing ring and the rotor shaft and surrounds the rotor shaft, a spiral rotational flow groove is formed in the annular channel, a first hole channel is formed between the oil cavity and the annular channel, a second hole channel is formed in the sealing ring, and the first hole channel is communicated with the second hole channel. One end of the second hole channel communicates with the annular channel, and the other end of the second hole channel is arranged close to the end of the hot-end bearing. The hot-end bearing has the beneficial effect that the lubricating and cooling effects of the hot-end bearing are improved. 一
