technical field

The utility model relates to the technical field of motor supporting components, in particular to a rotor assembly. The utility model also relates to a motor using the rotor assembly.

Background technique

Due to the eccentric mass of the rotating parts of the pump body, the centrifugal force and centrifugal moment of the pump body cannot be self-balanced when the pump body is in operation. Therefore, an eccentric mass part must be added to ensure its rotational balance during actual assembly and use.

In view of the above problems, the more common technology at present is to design the balance weight, and rivet the balance weight to the end of the rotor through rivets. Since the displacement of the compressor is different, the size and height of the eccentric portion of the rotor balance weight will also be different. If the rivet As the length varies with the height of the balance weight, there will be many kinds of rivets with different heights; if the length of the rivet needs to be used for a variety of rotors, counterbore holes will be required for the balance weight, and the matching structure between the components will also be complicated, which will lead to the overall processing of the device. Increased difficulty. At the same time, the balance weight and the rotor are riveted as a whole. During the assembly and final assembly of the rotor assembly, many special tools need to be designed to avoid the balance weight on the rotor. These tools have complex structures and low versatility, which causes a lot of inconvenience to related production and processing.

Therefore, how to simplify the assembly structure of the rotor assembly, improve its assembly efficiency and its component versatility is an important technical problem to be solved by those skilled in the art.
