Description

Technical Field

[0001] This utility model relates to the field of motor technology, and more specifically, to a rotor assembly structure for a low-friction, high-speed rotating motor. Background Technology

[0002] As industrial equipment places increasingly higher demands on motor performance, particularly in terms of high speed and high efficiency, traditional motor rotor structures have revealed numerous problems during high-speed operation. These include high frictional losses, high energy consumption, and severe heat generation during operation. These issues not only reduce the overall efficiency of the motor but also affect its operational stability and service life.

[0003] Because the rotor is subjected to both friction and high temperature during long-term operation, its key components are prone to wear, fatigue damage, and material aging. Furthermore, as wear intensifies, the rotor's dynamic balance may be disrupted, further affecting the stability and safety of the motor's operation, and even adversely impacting the continuous and efficient operation of the entire industrial system. Utility Model Content

[0004] This invention addresses the technical problems existing in the prior art by providing a low-friction, high-speed rotating motor rotor assembly structure. It solves the problem that the rotor, under the combined effects of continuous friction and high temperature during long-term operation, is prone to wear, fatigue damage, and material aging of its key components. Furthermore, as wear intensifies, the rotor's dynamic balance may be disrupted, further affecting the stability and safety of the motor's operation, and even adversely impacting the continuous and efficient operation of the entire industrial system.

[0005] To achieve the above objectives, this utility model provides a low-friction high-speed rotating motor rotor assembly structure, including a shaft and a rotor. The rotor is sleeved on the shaft, and a stator is sleeved on the rotor. A connecting ring is sleeved on the shaft, and a liquid storage cavity is formed in the connecting ring. The liquid storage cavity contains lubricating oil and a sponge sleeve. Multiple protrusions are circumferentially fixedly connected to the shaft, and multiple strip grooves are circumferentially formed on the shaft. The protrusions and strip grooves are staggered. Multiple vertical grooves are formed in the rotor. Multiple vertical grooves on the same circular cross section form a group, and the multiple vertical grooves are distributed on the rotor in multiple groups with equal axial spacing. Each vertical groove is connected to a strip groove. Multiple annular grooves are formed on the rotor, and multiple vertical grooves in the same group are connected to the same annular groove.

[0006] The beneficial effects of this utility model are:

[0007] As the shaft rotates at high speed, it drives the protrusion to rotate at high speed as well. The protrusion can squeeze the sponge sleeve, and the squeezed lubricating oil falls into the strip groove. The lubricating oil can lubricate and cool the shaft. Some of the lubricating oil flows from the strip groove into the vertical groove, and then into the ring groove, which cools and lubricates the rotor, avoiding the rotor from working in a high-temperature environment for a long time, reducing friction damage caused by high-speed rotation, and improving the service life of the rotor.

[0008] Preferably, a mounting ring plate is fixedly connected to the inner wall of the connecting ring sleeve, and the sponge sleeve is mounted on the mounting ring plate.

[0009] Preferably, two L-shaped fixing rods are symmetrically fixedly connected to the connecting ring, and the opposite ends of the two L-shaped fixing rods are fixedly connected to the stator.

[0010] Preferably, two mounting discs are fixedly connected to the rotating shaft, and the rotor is fixedly connected to the two mounting discs.

[0011] Preferably, a liquid inlet is fixedly inserted into the side wall of the connecting ring sleeve, and the liquid inlet is used to inject lubricating oil.

[0012] The advantage of adopting the above-mentioned further solution is that it provides auxiliary guiding force during disassembly and assembly, avoiding hard collisions between the shaft and the mounting base.

[0013] Preferably, the rotating shaft is fixedly connected to a mounting base, and the rotating shaft is mounted via the mounting base.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] As the shaft rotates at high speed, it drives the protrusion to rotate at high speed as well. The protrusion can squeeze the sponge sleeve, and the squeezed lubricating oil falls into the strip groove. The lubricating oil can lubricate and cool the shaft. Some of the lubricating oil flows from the strip groove into the vertical groove, and then into the ring groove, which cools and lubricates the rotor, avoiding the rotor from working in a high-temperature environment for a long time, reducing friction damage caused by high-speed rotation, and improving the service life of the rotor.

[0023] 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.

[0024] Please see Figures 1-5 This embodiment provides a low-friction high-speed rotating motor rotor assembly structure, including a shaft 1 and a rotor 2. The rotor 2 is sleeved on the shaft 1, and a stator 3 is sleeved on the rotor 2. During long-term operation, the rotor continuously endures the dual effects of friction and high temperature, which easily leads to wear, fatigue damage, and material aging of its key components. Considering that the rotor continuously endures the dual effects of friction and high temperature during long-term operation, which easily leads to wear, fatigue damage, and material aging of its key components, a connecting ring 4 is sleeved on the shaft 1. The connecting ring sleeve 4 has a liquid storage chamber containing lubricating oil and a sponge sleeve 5. The rotating shaft 1 is circumferentially fixed with multiple protrusions 6 and multiple strip grooves 7. The protrusions 6 and strip grooves 7 are staggered. The rotor 2 has multiple vertical grooves 8. Multiple vertical grooves 8 on the same circular cross section are grouped together. The multiple vertical grooves 8 are distributed axially at equal intervals on the rotor 2 in multiple groups. Each vertical groove 8 is connected to the strip groove 7. The rotor 2 has multiple annular grooves 9. Multiple vertical grooves 8 in the same group are connected to the same annular groove 9.

[0025] In summary, the improvement of this embodiment lies in:

[0026] While the shaft 1 rotates at high speed, it also drives the protrusion 6 to rotate at high speed. The protrusion 6 can squeeze the sponge sleeve 5, and the squeezed lubricating oil falls into the strip groove 7. The lubricating oil can lubricate and cool the shaft 1. Some of the lubricating oil flows from the strip groove 7 into the vertical groove 8, and then into the ring groove 9 to cool and lubricate the rotor 2. This avoids the rotor 2 from working in a high-temperature environment for a long time, reduces friction damage caused by high-speed rotation, and improves the service life of the rotor 2.

[0027] Based on the above, other structures also need to be disclosed in detail, such as:

[0028] Please see Figure 2 and Figure 3 Considering the need to install and fix the sponge sleeve 5, an installation ring plate 501 is fixedly connected to the inner wall of the connecting ring sleeve 4, and the sponge sleeve 5 is installed on the installation ring plate 501.

[0029] Please see Figure 1 and Figure 2 Considering the need to fix the position of the connecting ring sleeve 4, two L-shaped fixing rods 11 are symmetrically fixedly connected to the connecting ring sleeve 4. The opposite ends of the two L-shaped fixing rods 11 are fixedly connected to the stator 3, and the connecting ring sleeve 4 is fixed by the L-shaped fixing rods 11.

[0030] Please see Figure 1 and Figure 2 Considering the need to fix the rotor 2 on the rotating shaft 1, two mounting circular plates 10 are fixedly connected to the rotating shaft 1, and the rotor 2 is fixedly connected to the two mounting circular plates 10. The rotor 2 is fixedly mounted on the rotating shaft 1 by the mounting circular plates 10.

[0031] Please see Figure 2 and Figure 3 Considering the need to inject lubricating oil into the storage chamber, an inlet 401 is fixedly inserted into the side wall of the connecting ring sleeve 4. The inlet 401 is used to inject lubricating oil.

[0032] Please see Figure 2 Considering the need to install the rotating shaft 1, the rotating shaft 1 is fixedly connected to the mounting base 101, and the rotating shaft 1 is installed through the mounting base 101.

[0033] In summary, the working principle of this solution is as follows:

[0034] Lubricating oil is injected into the connecting ring 4 through the inlet 401. The sponge sleeve 5 absorbs the lubricating oil. While the rotating shaft 1 rotates at high speed, it drives the protrusion 6 to rotate at high speed as well. The protrusion 6 can squeeze the sponge sleeve 5, and the squeezed lubricating oil falls into the strip groove 7. The lubricating oil can lubricate and cool the rotating shaft 1. Some of the lubricating oil flows from the strip groove 7 into the vertical groove 8, and then into the ring groove 9 to cool and lubricate the rotor 2. This avoids the rotor 2 working in a high-temperature environment for a long time, reduces friction damage caused by high-speed rotation, and improves the service life of the rotor 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
