Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings.
[0015] like figure 1 and figure 2 As shown, the present invention discloses an installation structure of a silicon steel sheet on a magnetic levitation rotor, including a rotor core 1, a silicon steel sheet 2, a compression nut 3, a thrust plate 4 and a fixing screw 5, and the silicon steel sheet 2 is penetrated on the rotor iron core 1 On, and the interference fit between the silicon steel sheet 2 and the rotor core 1. A stepped hole 30 is provided in the axial direction of the compression nut 3, and the stepped hole 30 includes a large hole portion 31 and a small hole portion 32, and a connecting internal thread 33 is provided on the inner wall of the large hole portion 31. The end portion of 1 is provided with a stepped portion 11, and the silicon steel sheet 2 is installed on the stepped portion 11. A connection external thread 113 is provided on the step porti...

The invention discloses a mounting structure of a silicon steel sheet on a magnetic suspension rotor, and a mounting method for the silicon steel sheet. The mounting structure is characterized in thatthe silicon steel sheet is in interference fit with a rotor core; a step hole with a large hole part and a small hole part is formed in a pressing nut, and internal connection threads are formed on the inner wall of the large hole part; a step part is arranged at one end of the rotor core, and external connection threads are formed on the step part; the rotor core penetrates the pressing nut, andthe internal connection threads in the large hole part are in threaded connection with the external connection threads on the step part; the small hole part is in interference fit with the rotor core; and a thrust disc is fixedly connected with the pressing nut through fixing screws. The mounting structure has the advantages that the silicon steel sheet can be firmly pressed, and the thrust disccan be axially stressed; the connection threads on the pressing nut can provide a sufficient axial tensioning force; and through the design of an interference fit section of the pressing nut, a sufficient pressing force between the rotor core and the pressing nut is guaranteed, so that a gap between the pressing nut and the rotor core generated under the action of the centrifugal force during high-speed rotation is prevented.
