Description

Technical Field

[0001] This utility model relates to the field of rotor technology, and in particular to a multi-pitch variable cross-section composite toothed rubber screw rotor. Background Technology

[0002] The motor rotor is a key component of the motor, and its technological background is closely related to the development of motor technology, involving multiple aspects such as the establishment of electromagnetic theory, the advancement of manufacturing processes, and performance optimization under different application scenarios.

[0003] Most rotors on the market have their fixed end rings directly fixed to the outer periphery of the main shaft with glue, making it inconvenient to disassemble and reassemble the fixed end rings. Therefore, a multi-pitch variable cross-section composite toothed rubber screw rotor is needed. Utility Model Content

[0004] The purpose of this invention is to provide a multi-pitch variable cross-section composite toothed rubber screw rotor, which solves the problem in the prior art where most rotors have the fixed end ring directly fixed to the outer periphery of the main shaft with glue, making it inconvenient to disassemble and reassemble the fixed end ring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-pitch variable cross-section composite toothed rubber screw rotor, comprising a main shaft, with iron core sheets arranged around the periphery of the main shaft, metal rods penetrating through the interior of the multiple sets of iron core sheets, a fixed end ring at the top of the main shaft, a limit slide rail inside the fixed end ring, a limit slider on the inner side of the limit slide rail, a push plate fixed to the side wall of the limit slider, a damper on one side of the push plate, a spring around the damper, a locking plate fixed to the other side wall of the push plate, and a locking groove on the outer side of the locking plate.

[0006] Preferably, the sidewall of the fixed end ring is fixed with an arc-shaped blade.

[0007] Preferably, the push plate forms a sliding structure with the limiting slider and the limiting slide rail, the push plate forms an elastic structure with the fixed end ring through the damper and the spring, and the push plate forms a fixed structure with the locking plate.

[0008] Preferably, the locking plate forms a locking structure with the main rotating shaft through locking grooves. The locking grooves are provided with two sets symmetrically distributed about the center line of the main rotating shaft, and the outer contour of the main rotating shaft is adapted to the inner contour of the fixed end ring.

[0009] Preferably, the arc-shaped blades and the fixed end ring form a fixed structure, and the arc-shaped blades are evenly distributed on the side wall of the fixed end ring.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This multi-pitch variable cross-section composite toothed rubber screw rotor is equipped with a damper and a spring. By pushing the push plate with external force, the locking plate can be moved, thereby allowing for quick disassembly of the fixed end ring. Conversely, the locking structure of the locking plate and the locking groove can lock and fix the fixed end ring. The damper and spring allow the locking plate to automatically return to its original position after the force is removed, locking and fixing the fixed end ring. This allows for quick installation and fixation of the fixed end ring, and also facilitates subsequent disassembly of the fixed end ring. This avoids the situation where the fixed end ring is mostly fixed to the outside of the main shaft with glue, which makes it inconvenient to disassemble and reassemble the fixed end ring again.

[0012] 2. This multi-pitch variable cross-section composite toothed rubber screw rotor is equipped with arc-shaped blades. Multiple sets of arc-shaped blades are directly fixed to the side wall of the fixed end ring so that the rotation of the fixed end ring can drive the multiple sets of arc-shaped blades to rotate, thereby accelerating the airflow and having a cooling and heat dissipation effect on the rotor, increasing the rotor's service life. Secondly, the curved surface design of the arc-shaped blades is more in line with the principles of fluid mechanics (similar to the lift principle of an airfoil). When rotating, it can make the airflow on the blade surface more smoothly separated, reducing eddy current losses. Compared with straight blades, arc-shaped blades can drive more airflow and generate greater wind force, making the fan distance farther and the coverage wider. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, a multi-pitch variable cross-section composite toothed rubber screw rotor includes a main shaft 1. Iron core sheets 2 are arranged around the main shaft 1. Metal rods 3 penetrate through the interior of multiple sets of iron core sheets 2. A fixed end ring 4 is arranged at the top of the main shaft 1. A limit slide rail 5 is opened inside the fixed end ring 4. A limit slider 6 is arranged on the inner side of the limit slide rail 5. A push plate 7 is fixed on the side wall of the limit slider 6. A damper 8 is arranged on one side of the push plate 7. A spring 9 is arranged around the damper 8. A locking plate 10 is fixed on the other side wall of the push plate 7. A locking groove 11 is arranged on the outer side of the locking plate 10.

[0020] The push plate 7 forms a sliding structure with the limit slider 6 and the limit slide rail 5. The push plate 7 forms an elastic structure with the fixed end ring 4 through the damper 8 and the spring 9. The push plate 7 forms a fixed structure with the locking plate 10. When the push plate 7 is pushed by external force, the locking plate 10 can be moved, thereby allowing the fixed end ring 4 to be quickly disassembled. Conversely, the locking structure of the locking plate 10 and the locking groove 11 can lock and fix the fixed end ring 4.

[0021] The locking plate 10 forms a locking structure with the main rotating shaft 1 through the locking groove 11. The locking groove 11 is provided with two sets of symmetrically distributed about the center line of the main rotating shaft 1. The outer contour of the main rotating shaft 1 is adapted to the inner contour of the fixed end ring 4. The locking plate 10 can automatically return to its original position after the damper 8 and the spring 9 are provided, so as to lock and fix the fixed end ring 4. This allows for quick installation and fixation of the fixed end ring 4, and also facilitates the subsequent disassembly of the fixed end ring 4.

[0022] Example 2

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment further illustrates Example 1, wherein an arc-shaped blade 12 is fixed to the side wall of the fixed end ring 4.

[0024] The curved blades 12 and the fixed end ring 4 form a fixed structure, and the curved blades 12 are evenly distributed on the side wall of the fixed end ring 4. Multiple sets of curved blades 12 are directly fixed to the side wall of the fixed end ring 4 so that the rotation of the fixed end ring 4 can drive the multiple sets of curved blades 12 to rotate, thereby accelerating the airflow, cooling the rotor, and increasing the service life of the rotor. Secondly, the curved surface design of the curved blades 12 is more in line with the principles of fluid mechanics, similar to the lift principle of an airfoil. When rotating, it can make the airflow on the blade surface more smoothly separated, reducing eddy current losses. Compared with straight blades, the curved blades 12 can drive more airflow and generate greater wind force, making the fan distance farther and the coverage wider.

[0025] Working principle: First, multiple sets of iron core sheets 2 are stacked and pressed together. Then, the main rotating shaft 1 is inserted and fixed. Next, the metal rod 3 is inserted and fixed. Then, the push plate 7 is pushed by external force, which can drive the locking plate 10 to move, thereby allowing the fixed end ring 4 to be quickly disassembled. Conversely, the locking structure of the locking plate 10 and the locking groove 11 can lock and fix the fixed end ring 4. The damper 8 and the spring 9 can make the locking plate 10 automatically return to its original position after the force is lost, locking and fixing the fixed end ring 4. This allows for quick installation and fixation of the fixed end ring 4, and also facilitates subsequent disassembly of the fixed end ring 4. Multiple sets of arc-shaped blades 12 are directly fixed to the side wall of the fixed end ring 4, so that the rotation of the fixed end ring 4 can drive the multiple sets of arc-shaped blades 12 to rotate, thereby accelerating the air flow and having a cooling and heat dissipation effect on the rotor.
