Abstract

The invention discloses a structure for press mounting a stator and a rotor, which comprises an inner expansion cylinder and a positioning cylinder, wherein the inner expansion cylinder is assembled in the positioning cylinder and is in conical surface fit with the positioning cylinder; the positioning cylinder is assembled in an upper pressure plate and a lower pressure plate and is fixed on a cover plate through screws on the lower pressure plate; the cover plate is fixed on a base through the screws at a lower part; a mandrel is mounted in the centre of the inner expansion cylinder and runs through the cover plate; a positioning sleeve is mounted outside the mandrel and is positioned between the cover plate and the base; and positioning screws are mounted on the lateral surfaces of the positioning sleeve and are pressed tightly against a slider through a spring. Stress between the inner expansion cylinder and the positioning cylinder is changed into the stress of a whole conical surface due to the conical surface fit; and compared with point stress, the stress of the conical surface is easier to realize assembly and ensure an assembly tolerance, personally is not easy deformed or abraded, can be easily and automatically adjusted and balanced even if the stress of the conical surface is deformed or abraded, and can automatically correct the tolerance.

Description

technical field [0001] The invention relates to a three-phase asynchronous motor, in particular to a press-fit structure of a stator and rotor on the motor. Background technique [0002] The traditional three-phase asynchronous motor adopts the press-fit technology, and the force between the inner expansion cylinder and the positioning cylinder is only a point, the tolerance is not easy to be guaranteed, the assembly is inconvenient, and the point force is also easy to make the equipment easy to use after assembly. Deformation or wear will easily cause the rotation of the motor equipment to appear eccentric, which in turn will affect the overall service life of the motor equipment. [0003] And if the point force is converted into surface force, this can disperse the force, and the force-bearing surface is not easy to be deformed by force, and even if it is worn, it is easy to automatically correct the tolerance; at the same time, the surface force can ensure that the assemb...
