<p>Title: A BEARING-SHAFT ASSEMBLED STRUCTURE Abstract The invention relates to a bearing-shaft assembled structure, belonging to the technical field of bearing-shaft assembled structures. The structure comprises a rotor shaft and a yoke assembly fixed on the rotor shaft, and the parts of the rotor shaft corresponding to both ends of the yoke assembly are respectively provided with a left bearing and a right bearing. The structure is characterized in that the right bearing is a double row conical roller bearing, the rotor shaft between the yoke assembly and the inner end of the right bearing is provided with a bearing cap, and the part of the rotor shaft corresponding to the outer end of the right bearing is fitted with a screw nut by screw threads. The bearing-shaft assembled structure has simple structure and no axial movement between the rotor shaft and the bearing, solving the problems of the prior art that axial movement possibly causes axial displacement between a bearing used for supporting a rotor shaft and a stator and a rotor shaft and results in unreliable fit between the bearing and the rotor shaft and thus affects the running performance of a motor.
