[0020] Reference Figures 1 to 3 The present application will be further described as shown in Figure 1 , Figure 2 and Figure 3 a kind of high-speed drive motor shaft is shown in the retainer ring, the flat retainer ring is composed of first part 1 and second part 2, and the central angle of the first part 1 and the second part 2 is 180 °, the opening section 11 of the retainer ring is located at the middle position of the first part 1, and the mass of the first part 1 and the second part 2 is the same.
[0021] Specifically, the baffle ring is divided into the first part 1 and the second part 2 with the inner circle center as a reference, and the same mass of the first part 1 and the second part 2 can overcome the centrifugal force of the baffle ring due to the mass imbalance of the upper and lower parts of the baffle ring during high-speed operation of the motor, so that the operation is stable; the thickness of the flat baffle ring is uniform, so that the installation is stable and reliable.
[0022] In the embodiment of the application, the outer side of the two ends of the baffle ring close to the opening section 11 is provided with a widened protruding part 13 widened along the radial direction of the inner base ring 12, and the outer peripheral edge of the baffle ring is further provided with two groups of weight-reducing notches symmetrically distributed on the two sides of the opening section 11.
[0023] Specifically, the weight-reducing notches penetrate the baffle ring in the axial direction, and the weight-reducing notches are located on the side away from the opening section 11 of the corresponding widened protruding part 13. The provision of the widened protruding part 13 not only increases the strength of the two ends of the baffle ring, but also facilitates the provision of auxiliary structures at the two ends for convenient disassembly and installation of the baffle ring.
[0024] In the embodiment of the application, the weight-reducing notches include notches one 15 and notches two 16, and a counterweight protruding part 14 is formed between the notches one 15 and the notches two 16. The weight-reducing notches can balance the weight increased by the widened protruding part 13, and the counterweight protruding part 14 can strengthen the rigidity of the part of the baffle ring, prevent deformation and fatigue attenuation due to centrifugal force during high-speed operation, and make the baffle ring run stably and not fall off during high-speed operation, which is safe and reliable.
