Description

Technical Field

[0001] This utility model belongs to the field of motor technology, and specifically relates to a stable riveted rotor. Background Technology

[0002] The stationary part of an electric motor is called the stator, on which a pair of DC-excited stationary main magnetic poles are installed. The rotating part, the rotor, is called the armature core, on which armature windings are installed. When energized, these windings generate an induced electromotive force, which acts as a rotating magnetic field. This, in turn, produces electromagnetic torque for energy conversion. Based on the shape and mounting method of the stator windings, stator windings can be divided into two categories: centralized and distributed.

[0003] Traditional riveting processes cannot precisely control the rotor mass distribution and require additional counterweights to adjust the balance, which leads to structural complexity and reduced precision. Furthermore, traditional counterweight adjustment methods require damaging the rotor structure and are difficult to achieve in real-time dynamic compensation. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a riveted rotor with good balance and high stability.

[0005] The objective of this utility model can be achieved through the following technical solution: A stable riveted rotor includes a rotor body, which is composed of a stator and a rotor. The rotor is composed of several rotor cores with through holes. The rotor is characterized by having fixed covers at both ends, and the fixed covers having several connecting parts for stabilizing the fixed blocks. A cavity is formed between the fixed covers and the stator. A circumferential balancing groove is formed on the outer wall of the fixed covers. Several balancing units are installed in the balancing grooves. Each balancing unit has a balancing convex ring for installation in the balancing groove. The balancing convex ring has an annular slide rail groove. A ball bearing is located in the slide rail groove, and a fixed frame is installed on the ball bearing. The fixed frame is L-shaped. One end of the fixed frame is connected to the ball bearing via a support frame, and the support frame passes through the ball bearing. A mounting platform is located at the other end of the fixed frame. An elastic frame is located on the mounting platform, and a connecting block is located on the elastic frame. A balancing block is located on the connecting block.

[0006] In the aforementioned stable riveted rotor, the balancing convex ring is divided into two parts: a balancing ring and a convex block. T-shaped grooves are provided on both sides of the convex block. A return spring is provided in the T-shaped groove. A T-shaped button is provided on the return spring. The T-shaped button has a locking part for locking into the port of the T-shaped groove.

[0007] In the aforementioned stable riveted rotor, the fixed frame, elastic frame, connecting block, and balance block are an integral connection structure.

[0008] Compared with existing technologies, this stabilized riveted rotor's balancing unit can automatically adjust its position according to the unbalanced force during rotor rotation, achieving real-time compensation for rotor unbalanced force, effectively reducing rotor vibration. The balancing unit adopts a detachable design, making installation and disassembly convenient, and the debugging process is simple, which can improve production efficiency.

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2As shown, this stable riveted rotor includes a rotor body 1, which is composed of a stator 2 and a rotor 3. The rotor 3 is composed of several rotor cores with through holes. Fixed covers 4 are provided at both ends of the rotor 3, and several connecting pieces 5 for stabilizing the fixed blocks are provided on the fixed covers 4. A cavity is formed between the fixed covers 4 and the stator 2. The fixed covers 4 provide an installation base for the balancing units and, together with the stator 2, form a certain spatial structure, which is beneficial to the stable operation of the rotor 3. A balancing groove is circumferentially opened on the outer wall of the fixed covers 4, and several balancing units are installed in the balancing groove. The balancing groove provides an installation position for the balancing units, allowing them to be evenly distributed around the axis of the rotor 3, thereby effectively compensating for the unbalanced force of the rotor 3. A balancing convex ring 6 is provided on the balancing unit for installation in the balancing groove. A ring-shaped slide rail groove 7 is opened on the balancing convex ring 6, and a ball bearing 8 is provided in the slide rail groove 7. A fixing frame 9 is installed on the ball bearing 8. The fixed frame 9 is L-shaped, with one end connected to the ball bearing 8 via a support frame 10, and the support frame 10 passes through the ball bearing 8. The ball bearing 8 rolls in the slide rail groove 7, allowing the fixed frame 9 to rotate freely around the axis of the balancing convex ring 6. This design allows the balancing unit to automatically adjust its position according to the direction of the unbalanced force during the rotation of the rotor 3, thereby more effectively balancing the unbalanced force of the rotor 3. The other end of the fixed frame 9 has a mounting platform 11, on which there is an elastic frame 12. A connecting block 13 is provided on the elastic frame 12, and a balancing block 14 is provided on the connecting block 13. The fixed frame 9 serves as a support and connection, connecting the other components of the balancing unit together. The elastic frame 12 has a certain degree of elasticity, which can buffer the impact of the unbalanced force on the balancing block 14 during the rotation of the rotor 3, allowing the balancing block 14 to work more stably. The connecting block 13 is used to fix the balancing block 14 on the elastic frame 12, and the balancing block 14 balances the unbalanced force of the rotor 3 through its own mass.

[0014] To elaborate further, the balancing ring 6 is divided into two parts: a balancing ring 15 and a protrusion 16. T-shaped grooves 17 are provided on both sides of the protrusion 16. A return spring 18 is provided in the T-shaped groove 17, and a T-shaped button 19 is provided on the return spring 18. The T-shaped button 19 has a locking part 20 for locking into the port of the T-shaped groove 17. The balancing ring 6 is used to install the balancing unit in the balancing groove. Through the cooperation of the T-shaped button 19 and the T-shaped groove 17, a reliable connection between the balancing unit and the balancing groove is achieved. The return spring 18 can provide a certain elastic force when it is necessary to disassemble the balancing unit, so that the T-shaped button 19 can be smoothly disengaged from the locking part 20, which facilitates the installation and disassembly of the balancing unit.

[0015] To elaborate further, the fixed frame 9, the elastic frame 12, the connecting block 13, and the balance block 14 are an integrated connection structure.

[0016] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
