The invention discloses an elevator traction machine. According to the technical scheme, the elevator traction machine is characterized in that the elevator traction machine comprises a rotor and a stator fixed to the outside, and the rotor comprises an integrally-formed traction wheel; the rotor is provided with a rotating shaft in a penetrated manner, and the rotating shaft is arranged on the stator in a penetrating manner; a sealing bearing is arranged between the rotor and the stator and fixed to the rotor in a sleeving manner through a shrink fit technology, and the rotor is internally provided with an oil storage cavity; the oil storage cavity is filled with lubricant oil, and the stator is provided with an oil spilling cavity; both the oil storage cavity and the oil spilling cavity are communicated with the sealing bearing through oil ways, and the oil ways of the oil spilling cavity and the sealing bearing are internally provided with one-way valves, filtering meshes and the like; it should be guaranteed that lubricant oil in the oil ways flows in one direction, and it can be guaranteed that sweeps are deposited in the oil spilling cavity; meanwhile, when the rotor rotates, the lubricant oil liquid flows violently, and a great amount of heat in the bearing can be taken away; and therefore it is guaranteed that the temperature in the bearing cannot be excessively high.
