Description

Technical Field

[0001] This utility model relates to the field of electric motor rotor technology, specifically to an electric motor rotor structure with high stability. Background Technology

[0002] The rotor structure of an electric motor is a very critical part of the motor, and its main function is to generate torque and drive the load to rotate.

[0003] A search of Chinese patent CN219740061U reveals a motor rotor structure, including a rotating shaft with grooves at both ends. A rotor body is fitted onto the surface of the rotating shaft. A limiting block is fixedly connected to the surface of the rotating shaft on one side of the rotor body. A positioning block is installed on the side wall of the limiting block. A positioning groove matching the positioning block is formed on one side of the rotor body on the limiting block. A fixing component is provided on the other side of the rotor body and the rotating shaft. This invention, through the cooperation of the limiting block and the positioning block, enables the rotor body to be quickly positioned on the surface of the rotating shaft, thereby reducing the time required for position adjustment and improving assembly efficiency. Simultaneously, the use of the fixing component allows the rotor body to be quickly fixed on the rotating shaft, further improving the installation efficiency of the rotor body and enhancing its operational stability.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. When the motor rotor rotates at high speed, it will shake, resulting in low stability. It is easy to be damaged by long-term wear and is not convenient to disassemble and assemble the motor rotor structure. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly stable electric motor rotor structure.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] This utility model provides a highly stable electric motor rotor structure, including a shaft, a rotor body fixedly mounted on the outer side of the shaft, a first mounting bracket and a second mounting bracket provided on the shaft, two positioning blocks fixedly mounted on each of the first and second mounting brackets, two circular shells symmetrically fixedly mounted on each of the first and second mounting brackets, a first spring connected to the inner wall of each circular shell, a locking block adapted to the circular shell connected to the end of the first spring, a mounting mechanism jointly provided between the first and second mounting brackets, and a support mechanism jointly provided between the rotor body, the first mounting bracket, and the second mounting bracket.

[0008] Furthermore, the first mounting bracket and the second mounting bracket are fixedly mounted on the shaft by bearings.

[0009] Furthermore, the shaft is provided with multiple positioning grooves that are adapted to the positioning block.

[0010] Furthermore, two welding blocks are symmetrically arranged at the ends of both the first mounting bracket and the second mounting bracket, and each welding block has a slot that matches the card block.

[0011] Furthermore, the second mounting bracket has two circular holes, and the mounting mechanism includes two long bolts that are movably disposed inside the two circular holes respectively.

[0012] Furthermore, the mounting mechanism also includes two long sleeves fixedly mounted on the first mounting bracket, and the long sleeves are threadedly connected to the long bolt. The inner walls of the two long sleeves are each connected to a second spring, and the second spring abuts against the long bolt.

[0013] Furthermore, the support mechanism includes two ring blocks fixedly mounted on the rotor body, and ring shells adapted to the ring blocks are fixedly mounted on both the first mounting bracket and the second mounting bracket.

[0014] The above-described solution of this utility model has at least the following beneficial effects:

[0015] 1. In this utility model, by installing the first mounting bracket and the second mounting bracket to fix each other, and by supporting the ring block through the ring shell, the high-speed rotation of the rotor body is stably supported, thereby preventing the rotor body from shaking due to high-speed rotation. The mounting bracket increases stability and reduces wear.

[0016] 2. In this utility model, the first and second mounting brackets are installed by interlocking the locking block and the locking slot, and by connecting the long bolt and the long sleeve with a threaded connection. By unscrewing the long bolt out of the inner side of the long sleeve, the second spring can use its own elastic force to push the long bolt away from the long sleeve, and then the locking block is disassembled from the locking slot. There is no need to use complex parts for fixing, which makes it easier for workers to disassemble and assemble. Attached Figure Description

[0023] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0024] like Figures 1 to 4 As shown, an embodiment of this utility model provides a highly stable motor rotor structure, including a shaft 1. A rotor body 2 is fixedly mounted on the outer side of the shaft 1. A first mounting bracket 3 and a second mounting bracket 4 are provided on the shaft 1. Two positioning blocks 5 are fixedly mounted on both the first mounting bracket 3 and the second mounting bracket 4. Two circular shells 6 are symmetrically fixedly mounted on both the first mounting bracket 3 and the second mounting bracket 4. A first spring 7 is connected to the inner wall of each circular shell 6. A locking block 8 adapted to the circular shell 6 is connected to the end of the first spring 7. A mounting mechanism is provided between the first mounting bracket 3 and the second mounting bracket 4. The first mounting bracket 3 and the second mounting bracket 4 are fixed by bearings. The mounting mechanism is fixedly installed on the shaft 1. The shaft 1 has multiple positioning grooves that are adapted to the positioning block 5. The ends of the first mounting bracket 3 and the second mounting bracket 4 are symmetrically provided with two welding blocks 9. Each welding block 9 has a slot 10 that is adapted to the locking block 8. The second mounting bracket 4 has two round holes 11. The mounting mechanism includes two long bolts 12 that are movably disposed inside the two round holes 11. The mounting mechanism also includes two long sleeves 14 that are fixedly installed on the first mounting bracket 3. The long sleeves 14 are threadedly connected to the long bolts 12. The inner walls of the two long sleeves 14 are connected to a second spring 13, and the second spring 13 abuts against the long bolt 12.

[0025] The rotor body 2, the first mounting frame 3, and the second mounting frame 4 are all provided with a support mechanism. The support mechanism includes two ring blocks 15 fixedly installed on the rotor body 2. The first mounting frame 3 and the second mounting frame 4 are both fixedly installed with ring shells 16 that are adapted to the ring blocks 15.

[0026] In this embodiment of the utility model, the worker welds the welding block 9 onto the motor. The worker moves the first mounting bracket 3 and the second mounting bracket 4, causing the first mounting bracket 3 and the second mounting bracket 4 to move the positioning block 5 into the inner side of the positioning groove of the shaft 1 under the action of external force. The first mounting bracket 3 and the second mounting bracket 4 then move the locking block 8 into the inner side of the slot 10 through the round shell 6 and the first spring 7, respectively. The locking block 8 is then engaged with the slot 10 under the support of the elastic force of the first spring 7. The first mounting bracket 3 and the second mounting bracket 4 are installed by threading the long bolt 12 and the long sleeve 14. By unscrewing the long bolt 12 out of the inner side of the long sleeve 14, the second spring 13 can use its own elastic force to push the long bolt 12 away from the long sleeve 14. Then the locking block 8 is removed from the slot 10 for disassembly. This does not require the use of complex parts for fixing, thus facilitating the worker's disassembly and assembly work.

[0027] Workers fix the first mounting bracket 3 and the second mounting bracket 4 together, and support the ring block 15 with the ring shell 16, thereby providing stable support for the high-speed rotation of the rotor body 2, which can prevent the rotor body 2 from shaking due to high-speed rotation. The mounting bracket increases stability and reduces wear.

[0028] Working principle: The worker welds the welding block 9 onto the motor. By moving the first mounting bracket 3 and the second mounting bracket 4, the worker moves the positioning block 5 into the inner side of the positioning groove of the shaft 1. Under the support of the spring force of the first spring 7, the locking block 8 engages with the slot 10. The first mounting bracket 3 and the second mounting bracket 4 are installed by threading the long bolt 12 and the long sleeve 14. By unscrewing the long bolt 12 out of the long sleeve 14, the second spring 13 can use its own elastic force to push the long bolt 12 out of the long sleeve 14, and then the locking block 8 is disassembled from the slot 10. The worker fixes the first mounting bracket 3 and the second mounting bracket 4 together and supports the ring block 15 through the ring shell 16, thereby providing stable support for the high-speed rotation of the rotor body 2.

[0029] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
