Abstract

The invention provides a rotating shaft, an assembling method thereof and a motor. The rotating shaft comprises a shaft sleeve, a first shaft section, a second shaft section and a magnetic shaft section; one end of the first shaft section is located in the shaft sleeve, one end of the second shaft section is located in the shaft sleeve; a containing cavity is formed between the inner wall of the shaft sleeve and the first and second shaft sleeves; the magnetic shaft section is located in the containing cavity; and connecting parts used for connecting with the magnetic shaft section are arranged on the end faces of both the first shaft section and the second shaft section. As the connecting parts are respectively arranged on the end faces of the first shaft section and the second shaft section, the reliability of the rotating shaft is increased efficiently. As a three-section type connecting mode is adopted by the rotating shaft, the axial magnetic circuit of the rotating shaft is blocked efficiently and the axial leakage flux is reduced. As auxiliary installation of complex assembly equipment tooling is unnecessary for the rotating shaft, the assembling speed of the rotating shaft is increased efficiently.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a rotating shaft, an assembly method for the rotating shaft, and a motor. Background technique [0002] The high-speed permanent magnet motor rotor structure in the prior art adopts segmented annular magnetic steel, and the rotor also adopts a segmented structure (see figure 1 ), connect the segmented magnetic steel 2 and the end pieces 4 and 5 at both ends through a threaded guide rod 3 at both ends (processed to the same outer diameter size of each component), and then heat through the sheath 1 at one time Assembly is complete. Hot loading is relatively simple, but the structure is slightly more complicated. [0003] In addition, another common high-speed permanent magnet motor rotor structure in the prior art, the motor rotor adopts a whole ring magnet (surface-mounted magnet), and the rotor adopts a main shaft, which protects the magnet and transmits torque through ...
