Description

Technical Field

[0002] In rotating equipment such as motors, generators, and compressors, the rotor is the rotating part, which is opposite to the stator. In motors, the rotor is usually composed of conductive coils or permanent magnets, and moves under the action of the magnetic field after power is applied; in generators, the movement of the rotor cuts the magnetic flux lines to generate current. The performance of the rotor directly affects the working efficiency and stability of the entire equipment. Among them, non-step shaft rotors are mostly shafts with a circlip groove structure, and a circlip is installed in the circlip groove to limit the axial position of the bearing.

[0003] The current assembly of retaining rings is generally carried out by pure manual assembly method, or as Figure 1 As shown, place the circlip body in the lower tooling, use an air press to align the circlip groove of the rotor with the circlip body, and press it down into the circlip. This requires that the circlip groove of the rotor be aligned with the circlip body, resulting in a low yield rate and low assembly efficiency. Utility Model Content
