Description

Technical Field

[0001] This utility model belongs to the technical field of motor rotor equipment, specifically relating to a shock-absorbing rotor with self-locking function. Background Technology

[0002] An electric motor, also known as a motor or electric motor, is a device that converts electrical energy into mechanical energy. Electric motors are divided into two main product series: DC motors and AC motors. DC motors are primarily used for control applications. They consist of stator poles, rotor, commutator, brushes, housing, and bearings. They are widely used in machine tools, machinery, medical equipment, electronics, dishwashers, electric shavers, hair dryers, toys, and household appliances. AC motors are mainly used for powering equipment. After a three-phase AC power supply is input to the stator windings, the rotating magnetic field generated by the winding current induces a current in the rotor conductors. The rotor rotates under the interaction of this induced current and the rotating magnetic field in the air gap. They are widely used in industry, including lifting equipment, plastics machinery, papermaking, printing, ports, dams, and other mechanical equipment.

[0003] In the existing technology, the vibration generated by the motor during long-term operation can easily cause the injection molded parts to loosen from the inner and outer rings of the rotor, thereby affecting the service life of the motor. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a shock-absorbing rotor with a self-locking function. By fixing the ends of the outer iron core to both ends of the outer iron core body and setting the stops at intervals in the mounting groove, the inner iron core assembly is inserted into the outer iron core assembly. By rotating the inner iron core assembly at a certain angle, the stops are made to abut against both ends of the inner iron core assembly for limiting. Then, the gap between the inner iron core assembly and the outer iron core assembly is fixed by injection molding through the shock absorber to ensure the connection stability between the inner iron core and the outer iron core. It can also effectively absorb the vibration generated by the impeller and volute during the operation of the motor, reduce the noise generated by the whole machine operation, and improve the operating efficiency of the motor.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A self-locking damping rotor includes: an inner core assembly; an outer core assembly sleeved on the outside of the inner core assembly and coaxially arranged with the inner core assembly; magnetic tiles circumferentially distributed on the outside of the outer core assembly; and a damping body. The outer core assembly includes an outer core end and an outer core body. The outer core end is fixedly connected to both ends of the outer core body. The inner holes of both the outer core end and the outer core body are circumferentially distributed with mounting grooves. The mounting grooves are matched with the inner core assembly. A stop block is provided at intervals in the mounting groove located at the outer core end. When the inner core assembly is inserted into the outer core assembly, the stop block limits the inner core assembly after the inner core assembly is rotated. The inner core assembly and the outer core assembly are fixed by the damping body through plastic sealing. This invention fixes the ends of the outer iron core to both ends of the outer iron core body, and sets stop blocks at intervals in the mounting groove. The inner iron core assembly is inserted into the outer iron core assembly. By rotating the inner iron core assembly at a certain angle, the stop blocks are made to abut against both ends of the inner iron core assembly for limiting. Then, the gap between the inner iron core assembly and the outer iron core assembly is fixed by injection molding through a shock absorber to ensure the connection stability between the inner and outer iron cores. It can also effectively absorb the vibration generated by the impeller and volute during the operation of the motor, reduce the noise generated by the whole machine operation, and improve the operating efficiency of the motor.

[0007] Furthermore, the outer core assembly includes outer core lamination 1 and outer core lamination 2. Several outer core lamination 1 are stacked to form the outer core end, and several outer core lamination 2 are stacked to form the outer core body. The outer core end and the outer core body adopt a separate lamination stacking method. The stacking effect formed by the lamination stacking process enhances the overall structural rigidity. At the same time, the layered design facilitates mold development and mass production, and also facilitates the assembly of outer core assemblies of various sizes, significantly reducing manufacturing costs.

[0008] Furthermore, the outer wall of the outer core assembly has protrusions distributed around its circumference, with mounting grooves forming between adjacent protrusions. These mounting grooves are used to install the magnetic tiles. The precise distribution of the protrusions ensures the circumferential uniformity of the magnetic tile installation and optimizes the magnetic field distribution characteristics. The mounting grooves provide a quick positioning function for the installation of the magnetic tiles.

[0009] Furthermore, it also includes an injection-molded body. After the magnetic tile is embedded in the second mounting groove, it is fixed by molding with the injection-molded body. The injection molding process completes the fixing of the magnetic tile and surface encapsulation in one step, improving production efficiency. The injection-molded body can be made of PBT material.

[0010] Furthermore, the inner core assembly includes inner core lamination 1 and inner core lamination 2. Several inner core lamination 1 are stacked to form the inner core end, and several inner core lamination 2 are stacked to form the inner core body. The inner core end is fixedly connected to both ends of the inner core body. The inner core assembly adopts a lamination stacking design, which matches the outer core assembly. The stacking effect formed by the lamination stacking process enhances the overall structural rigidity. At the same time, the layered design facilitates mold development and mass production, and also facilitates the assembly of inner core assemblies of various sizes, significantly reducing manufacturing costs.

[0011] Furthermore, the outer circumference of the inner core body has two protrusions, which correspond to the mounting groove. The precise fit between the two protrusions and the mounting groove enables assembly guidance. The two protrusions increase the contact area, improve torque transmission capability, and provide a better adhesion base for the shock absorber.

[0012] Furthermore, the inner core has a ring-shaped structure at its ends.

[0013] Furthermore, both inner core lamination 1 and inner core lamination 2 have circumferentially distributed positioning holes. The positioning holes 1 serve to position the inner core end and the inner core body during overlapping, and during injection molding, they serve to fix the inner core assembly, ensuring the coaxiality of the inner core assembly and the outer core assembly.

[0014] Furthermore, both outer core lamination 1 and outer core lamination 2 have positioning holes 2 distributed around their circumference. The positioning holes 2 are designed to position the outer core end and the outer core body during the stacking process. During injection molding, they also serve to fix the outer core assembly, ensuring the coaxiality of the inner core assembly and the outer core assembly.

[0015] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0016] This invention fixes the ends of the outer iron core to both ends of the outer iron core body, and sets stop blocks at intervals in the mounting groove. The inner iron core assembly is inserted into the outer iron core assembly. By rotating the inner iron core assembly at a certain angle, the stop blocks are made to abut against both ends of the inner iron core assembly for limiting. Then, the gap between the inner iron core assembly and the outer iron core assembly is fixed by injection molding through a shock absorber to ensure the connection stability between the inner and outer iron cores. It can also effectively absorb the vibration generated by the impeller and volute during the operation of the motor, reduce the noise generated by the whole machine operation, and improve the operating efficiency of the motor.

Several outer core laminations 1 are stacked to form the outer core end, and several outer core laminations 2 are stacked to form the outer core body. The outer core end and the outer core body are assembled using a separate lamination stacking process. The stacking effect created by the lamination stacking process enhances the overall structural rigidity. Simultaneously, the layered design facilitates mold development and mass production, and also facilitates the assembly of outer core assemblies of various sizes, significantly reducing manufacturing costs.

[0018] This invention features a circumferential distribution of protrusions on the outer wall of the outer core assembly. A mounting groove (II) is formed between adjacent protrusions, used for mounting the magnetic tile. The precise distribution of the protrusions ensures circumferential uniformity of the magnetic tile installation and optimizes the magnetic field distribution characteristics.

[0030] like Figures 1 to 9 As shown, this utility model discloses a shock-absorbing rotor with a self-locking function, comprising: an inner core assembly 1; an outer core assembly 2, sleeved on the outside of the inner core assembly 1 and coaxially arranged with the inner core assembly 1; magnetic tiles 3, circumferentially distributed on the outside of the outer core assembly 2; and a shock absorber 4. The outer core assembly 2 includes an outer core end 5 and an outer core body 6. The outer core end 5 is fixedly connected to both ends of the outer core body 6. The inner holes of both the outer core end 5 and the outer core body 6 are circumferentially distributed with mounting grooves 7, which are matched with the inner core assembly 1. A stop block 8 is provided at intervals in the mounting groove 7 located in the outer core end 5. When the inner core assembly 1 is inserted into the outer core assembly 2, after the inner core assembly 1 is rotated, the stop block 8 limits the inner core assembly 1. The inner core assembly 1 and the outer core assembly 2 are fixed by the shock absorber 4 through plastic sealing.

[0031] The outer core assembly 2 includes outer core lamination 19 and outer core lamination 20. Several outer core laminations 19 are stacked to form the outer core end 5, and several outer core laminations 20 are stacked to form the outer core body 6. The outer core end 5 and the outer core body 6 are stacked in a separate lamination configuration. The stacking effect created by the lamination stacking process enhances the overall structural rigidity. Simultaneously, the layered design facilitates mold development and mass production, and also facilitates the assembly of outer core assemblies 2 of various sizes, significantly reducing manufacturing costs. The outer outer wall of the outer core assembly 2 has protrusions 11 distributed circumferentially. A mounting groove 22 is formed between two adjacent protrusions 11, used to install the magnetic tile 3. The precise distribution of the protrusions 11 ensures the circumferential uniformity of the magnetic tile 3 installation, optimizing the magnetic field distribution characteristics. The mounting groove 22 provides a quick positioning function for the installation of the magnetic tile 3. Both the outer core laminations 19 and 20 have positioning holes 20 distributed circumferentially. The positioning hole 20 serves to position the overlapping of the outer core end 5 and the outer core body 6. During injection molding, it also serves to fix the outer core assembly, ensuring the coaxiality of the inner core assembly 1 and the outer core assembly 2.

[0032] It also includes an injection molded body 13, which fixes the magnetic tile 3 after it is embedded in the mounting groove 12 by molding. The injection molding process completes the fixing and surface encapsulation of the magnetic tile 3 in one step, improving production efficiency.

Several inner core laminations 14 are stacked to form inner core end pieces 16, and several inner core laminations 15 are stacked to form inner core body 17. The inner core end pieces 16 are fixedly connected to both ends of the inner core body 17. The inner core assembly 1 adopts a lamination stacking design, matching the outer core assembly 2. The stacking effect formed by the lamination stacking process enhances the overall structural rigidity. Simultaneously, the layered design facilitates mold development and mass production, and also facilitates the assembly of inner core assemblies 1 of various sizes, significantly reducing manufacturing costs. The outer circumference of the inner core body 17 has protrusions 18, which correspond to mounting grooves 7. The precise fit between protrusions 18 and mounting grooves 7 achieves assembly guidance. Protrusions 18 increase the contact area, improve torque transmission capability, and provide a better adhesion base for the shock absorber 4. The inner core end pieces 16 have a ring-shaped structure. Both inner core lamination 14 and inner core lamination 15 have circumferentially distributed positioning holes 19. The positioning holes 19 are used to position the inner core end 16 and the inner core body 17 during the stacking process. During injection molding, they are used to fix the inner core assembly and ensure the coaxiality of the inner core assembly 1 and the outer core assembly 2.

[0034] This invention fixes the outer iron core end 5 to both ends of the outer iron core body 6, and sets stop blocks 8 at intervals in the mounting groove 7. The inner iron core assembly 1 is inserted into the outer iron core assembly 2. By rotating the inner iron core assembly 1 at a certain angle, the stop blocks 8 are made to abut against both ends of the inner iron core assembly 1 for limiting. Then, the gap between the inner iron core assembly 1 and the outer iron core assembly 2 is fixed by injection molding through the shock absorber 4, which ensures the connection stability between the inner iron core and the outer iron core. It can also effectively absorb the vibration generated by the impeller and volute during the operation of the motor, reduce the noise generated by the whole machine operation, and improve the operating efficiency of the motor.
