Therefore, a corrosion-resistant motor rotor shaft assembly structure is required.

[0003] When operators assemble the rotor shaft, they often use the corresponding motor rotor shaft assembly structure. Although the existing structure can achieve the assembly function, the rotor shaft will move in the axial direction during actual use, which is not conducive to the stable use of the motor. In addition, the positioning method of the rotor shaft is single, which makes it inconvenient to install and disassemble it, and its practicality is reduced. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The present invention relates to a corrosion-resistant motor rotor shaft assembly structure. During daily use, the operator slides the disc, and the disc drives the connecting pipe to slide when sliding, and then the connecting pipe drives the clamping block to slide until the clamping block is placed inside the clamping slot. At this time, the front cover is moved, and the front cover drives the sealing plate to slide when sliding, and then the front cover is placed on the outer surface of the shell, and then the fixing block is placed on the inner surface of the shell. At the same time, the fixing bolt is rotated and screwed into the shell and the fixing bolt to fix the front cover. Then the rear cover is moved and pressed against the other side of the shell, and then the mounting bolt is rotated and screwed into the rear cover and the shell to fix the rear cover. When the rotor rotates, it drives the rotor shaft to rotate. The provided clamping block, connecting pipe and disc can prevent the rotor shaft from axial movement, thereby improving the stability of the motor during operation.

[0013] This corrosion-resistant motor rotor shaft assembly structure has a process of daily use in which an operator places a sealing gasket inside a storage groove and then slides a circular plate.
