[0020] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0021] Reference Figure 1-4 The utility model embodiment is a high-strength bearing rotating mechanism, which includes: a mounting base 1, a mounting plate 2 and a servo motor 3 are fixedly connected to the upper surface of the mounting base 1, a transmission part of the servo motor 3 passes through the mounting plate 2, a load-bearing plate 9 is fixedly connected to the upper surface of the mounting plate 2, and a plurality of reinforcement holes 14 are arranged on the surfaces of the mounting base 1, the mounting plate 2 and the load-bearing plate 9. The above devices cooperate with each other to form a protective mechanism for the rotating mechanism.

[0022] The servo motor 3 passes through the mounting plate 2 and is fixedly connected to a driving gear 7. A driven gear 5 is arranged on the upper surface of the mounting plate 2. The tooth surface of the driving gear 7 is in close contact with the tooth surface of the driven gear 5, and the upper surface of the driven gear 5 is fixedly connected to the lower surface of the load-bearing plate 9. The above devices cooperate with each other to form a rotating mechanism. A protective shell 4 is fixedly connected to the upper surface of the mounting plate 2. The protective shell 4 surrounds the driven gear 5, and the upper surface of the protective shell 4 is fixedly connected to the lower surface of the load-bearing plate 9. The protective shell 4 ensures that the internal components of the rotating mechanism will not be exposed to the outside, and the protective shell 4 has a certain buffering capacity, which can alleviate the gravity exerted on the rotating mechanism.

[0023] A deep groove ball bearing 11 is arranged at the center point of the upper surface of the mounting plate 2, and a thrust ball bearing 10 is arranged on the upper surface of the deep groove ball bearing 11. The lower surface of the thrust ball bearing 10 is in close contact with the upper surface of the deep groove ball bearing 11, and the upper surface of the thrust ball bearing 10 is in close contact with the lower surface of the load-bearing plate 9. The thrust ball bearing 10 and the deep groove ball bearing 11 cooperate with each other to facilitate the relief of the gravity exerted on the load-bearing plate 9 and improve the carrying capacity of the rotating mechanism.

[0024] A mounting groove 12 is provided at the center point of the mounting plate 2, and the deep groove ball bearing 11 is located inside the mounting groove 12. The existence of the mounting groove 12 increases the tightness of the rotating mechanism itself. The bottom wall of the mounting groove 12 is rotatably connected with a connecting rod 6, and the upper surface of the connecting rod 6 is in close contact with the load-bearing plate 9. The existence of the connecting rod 6 interconnects the mounting plate 2, the thrust ball bearing 10, the deep groove ball bearing 11, and the load-bearing plate 9. At the same time, the connecting rod 6 has the function of limiting the moving range of the bearing mechanism, ensuring that the rotating mechanism can still rotate normally after the load-bearing plate 9 is subjected to an axial load.

[0025] A docking slot 8 is provided at the center point of the load-bearing plate 9, and the upper end of the connecting rod 6 is located inside the docking slot 8. The existence of the docking slot 8 improves the tightness of the internal structure of the rotating mechanism. A support pad 13 is fixedly connected to the inside of the mounting groove 12, and the inner wall of the support pad 13 is in close contact with the side surface of the deep groove ball bearing 11. The existence of the support pad 13 reduces the friction between the deep groove ball bearing 11 and the mounting plate 2.

[0026] Working principle: When the rotating mechanism is in use, the torque generated by the rotation of the servo motor 3 drives the active gear 7 to rotate, and the active gear 7 drives the driven gear 5 to rotate. The driven gear 5 is fixedly connected to the bearing plate 9 with bolts, so that the driven gear 5 drives the bearing plate 9 to rotate. When the bearing plate 9 is subjected to axial load, the thrust ball bearing 10 under the bearing plate 9 bears the axial force to ensure that the upper bearing plate 9 does not move. The thrust ball bearing 10 cooperates with the mounting plate 2 to fix the thrust ball bearing 10, and the deep groove ball bearing 11 is installed. The connecting rod 6 passes through the bottom, and the mounting plate 2, the thrust ball bearing 10, the deep groove ball bearing 11 and the bearing plate 9 are fixedly connected by tightening the nut, so as to ensure that the rotating mechanism can still rotate normally after the bearing plate 9 is subjected to axial load.

[0027] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
