Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor stators and rotors, in particular to a high-reliability vibration-absorbing motor stator and rotor. Background Art
[0002] The stator and rotor of an electric motor generally refer to the two main components within the motor: the stator and the rotor. The stator is the stationary part of the motor, typically consisting of an iron core and windings (coils). It is responsible for generating the magnetic field around which the rotor moves. The motor's power supply is connected to the stator, and the stator windings generate a rotating magnetic field when energized. The rotor is the rotating part of the motor, opposite the stator and usually contained within the stator. The rotor operates the motor through the magnetic field generated by the stator. The rotor can be an induction rotor or a permanent magnet rotor. The rotor rotates in response to the stator's magnetic field, converting electrical energy into mechanical energy.
[0003] In existing technologies, the stator and rotor vibration reduction structure of the motor usually relies on simple vibration reduction materials or fixed brackets for vibration reduction. Although it can reduce vibration to a certain extent, these traditional designs often cannot provide sufficient vibration reduction effect when facing complex working conditions or severe impact. Especially when the motor is running under high load, the vibration transmission will cause increased wear of motor components and may even cause equipment failure. In addition, the adaptability of traditional vibration reduction structures is poor, and it cannot be dynamically adjusted according to changes in vibration frequency or intensity, resulting in unstable vibration reduction effect, affecting the long-term reliability of the motor system.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Example 1
[0025] like Figure 1-As shown in the figure, the utility model provides a technical solution: a high-reliability shock-absorbing motor stator and rotor, comprising: a shock-absorbing mechanism 1, an auxiliary mechanism 2 is provided on the inner surface of the shock-absorbing mechanism 1, the shock-absorbing mechanism 1 comprises an arc-shaped arm 111, a spring piece 110 is provided at the middle end of the arc-shaped arm 111, the middle end of the arc-shaped arm 111 is fixedly connected to the top end of the spring piece 110, the bottom end of the spring piece 110 is provided with a fitting plate 19, the bottom end of the spring piece 110 is fixedly connected to the top side of the fitting plate 19 The outer side of the bonding plate 19 is provided with a triangular plate 15, and the outer side of the bonding plate 19 is in rotational contact with one side of the triangular plate 15. An inner ring 14 is provided at one end of the triangular plate 15, and one end of the triangular plate 15 is fixedly connected to the inner side of the inner ring 14. An outer ring 11 is provided at the outer side of the inner ring 14, and the outer side of the inner ring 14 is located on the inner side of the outer ring 11. An annular groove 113 is provided on the inner side of the outer ring 11. A side plate 13 is provided on the inner wall of the inner ring 14, and the inner wall of the inner ring 14 is in contact with the side plate One side of the inner ring 14 is in movable contact, and the other side of the side plate 13 is provided with a curved plate 12. The other side of the side plate 13 is fixedly connected to one end of the curved plate 12. An empty tube 16 is provided on one side of the inner ring 14. One side of the inner ring 14 is fixedly connected to one end of the empty tube 16. A limiting rod 17 is provided on the inner surface of the empty tube 16. The inner surface of the empty tube 16 corresponds to one end of the limiting rod 17. A fixing member 18 is provided on the inner wall of one end of the side of the limiting rod 17. The inner wall of one end of the surface is threadedly connected to the outer side of the fixing piece 18, the outer side of one end of the fixing piece 18 is threadedly connected to the inner wall of one end of the side of the empty tube 16, one end of the limiting rod 17 is connected through the inner wall of the inner ring 14, one end of the limiting rod 17 is correspondingly engaged with the inner wall of the side plate 13, one end of the curvature plate 12 is fixedly connected to the inner side of the outer ring 11, a rubber pad 112 is provided on one side of the arc arm 111, and one side of the arc arm 111 is fixedly connected to one side of the rubber pad 112.
[0026] In this embodiment, when the stator and rotor of this type of high-reliability shock-absorbing motor are in use, the stator and rotor are placed in five bonding plates 19, and the inner ring 14 is rotated, so that the inner triangular plate 15 exerts an external force on the bonding plate 19 during the rotation and forces it to contact the stator and rotor. In this process, since the bonding plate 19 is affected, the related connected components will also change. Since a spring piece 110 is installed on the top side of the bonding plate 19, the other end of the spring piece 110 is connected to the middle end of the arc arm 111.

When the empty tube 16 on the inner ring 14 rotates to the recessed hole, the limiting rod 17 in the empty tube 16 is clamped into the recessed hole of the side plate 13. Then, by connecting the fixing part 18 on the limiting rod 17 with the empty tube 16, the limiting rod 17 can remain in place after being clamped, preventing the inner ring 14 from rotating during operation, thereby maintaining the stability and accuracy of the system.

The inner wall of one end of the folding rod 21 is movably connected to the middle end of the pulley 22, the outer side of the pulley 22 is movably connected to the inner surface of the annular groove 113, and the other end of the folding rod 21 is fixedly connected to one end of the arc arm 111.
[0030] In this embodiment, when the arc-shaped arm 111 is subjected to external force, a folding rod 21 is installed at one end of the arc-shaped arm 111, and a pulley 22 is designed in the inner wall of the folding rod 21, which is inclined. Therefore, when subjected to external force, the pulley 22 will slide in the annular groove 113 in the outer ring 11, which can help disperse the stress applied to the arc-shaped arm 111, reduce local stress concentration, and improve the tolerance of the system. The movement trajectory of the folding rod 21 makes the movement smoother. This design enables the arc-shaped arm 111 to freely adjust its position when subjected to external force and maintain good movement performance.
