Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically to a high-speed motor dual-bearing anti-vibration component. Background Technology

[0002] When a high-speed motor is running, the centrifugal force and vibration increase significantly due to its extremely high speed. A single bearing is insufficient to meet the requirements for stable rotor support and precise positioning. Therefore, a dual-bearing structure is often used to ensure smooth motor operation, reduce vibration, and improve accuracy.

[0003] Existing dual-bearing high-speed motors can effectively distribute the rotor load, thereby improving the motor's operational stability to a certain extent, enhancing its ability to withstand centrifugal forces generated by high-speed rotation, and reducing the wear of individual bearings. However, existing dual-bearing high-speed motors still have shortcomings in vibration resistance. When faced with vibrations under complex working conditions, the synergistic vibration resistance effect of the dual bearings is poor, making it difficult to effectively suppress vibration transmission and easily affecting motor performance and service life. Therefore, there is an urgent need for a dual-bearing vibration-resistant component for high-speed motors to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed motor dual-bearing anti-vibration component to solve the problems mentioned in the background art, such as the shortcomings of existing dual-bearing high-speed motors in terms of vibration resistance, poor anti-vibration effect of dual bearings in the face of complex working conditions, difficulty in effectively suppressing vibration transmission, and easy impact on motor performance and service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-speed motor dual-bearing anti-vibration assembly, including a rotor shaft, two mutually symmetrical bearings are installed on the outer surface of the rotor shaft, and a buffer mechanism is provided on the outside of each of the two bearings. The buffer mechanism includes an annular frame and a connecting ring. An annular groove is provided on the inner side wall of the annular frame, and multiple nested annular rings are provided inside the annular groove. A second elastic pad is fixedly connected between any two annular rings that are close to each other.

[0006] The outer surface of the connecting ring is fixedly connected to the inner wall of the innermost annular ring, and the inner wall of the connecting ring is fixedly connected to the outer ring of the bearing.

[0007] The outer surface of the outermost annular ring is fixedly connected to the inner wall of the annular groove, and both the left and right sides of the connecting ring are in contact with the inner wall of the annular groove.

[0008] The output end of the rotor shaft is provided with a buffer hole, and multiple sliding plates are slidably connected to the inner sidewall of the buffer hole.

[0009] Each of the multiple sliding plates is fixedly connected with a first elastic pad, and the left side of the leftmost sliding plate is fixedly connected to the inner wall of the buffer hole.

[0010] A sliding rod is fixedly connected to the right side of the rightmost sliding plate, and the outer surface of the sliding rod is slidably connected to the inner wall of the buffer hole.

[0011] A sleeve is slidably connected to the right side of the outer surface of the rotor shaft, and the inner wall of the sleeve is fixedly connected to the right end of the sliding rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model discloses a high-speed motor dual-bearing anti-vibration component. By setting a buffer mechanism on the outside of the bearing, multiple annular rings are nested in the annular groove on the inner sidewall of the annular frame and connected by a second elastic pad. When the high-speed motor vibrates during operation, the annular rings can generate relative displacement within the annular groove. The elastic deformation of the second elastic pad can effectively absorb and disperse vibration energy, greatly reducing the direct impact of vibration on the bearing. This allows the two bearings to work together efficiently to resist vibration under complex working conditions, significantly suppressing vibration transmission, effectively improving the stability of motor operation, and thus extending the service life of the motor.

[0014] 2. This utility model discloses a high-speed motor dual-bearing anti-vibration assembly. By setting a buffer structure consisting of a sliding plate, a first elastic pad, a sliding rod, and a sleeve at the output end of the rotor shaft, multiple sliding plates are connected by the first elastic pad, and the sliding rod cooperates with the sleeve. When the motor generates axial vibration, the sliding plate can slide within the buffer hole, and the first elastic pad undergoes elastic deformation to buffer and absorb the axial vibration, further enhancing the anti-vibration performance of the entire assembly. This ensures that the rotor shaft is positioned more accurately when the motor is running at high speed, reduces component wear and precision reduction caused by vibration, and improves the overall performance of the motor.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a high-speed motor dual-bearing anti-vibration component, including a rotor shaft 1. Two symmetrical bearings 2 are mounted on the outer surface of the rotor shaft 1. A buffer mechanism 3 is provided on the outside of each bearing 2. The buffer mechanism 3 includes an annular frame 301 and a connecting ring 305. An annular groove 302 is formed on the inner side wall of the annular frame 301. Multiple nested annular rings 303 are arranged inside the annular groove 302. A second elastic pad 304 is fixedly connected between any two adjacent annular rings 303. The outer surface of the connecting ring 305 is fixedly connected to the inner side wall of the innermost annular ring 303. The inner side wall of the connecting ring 305 is fixedly connected to the outer ring of the bearing 2. The outer surface of the outermost annular ring 303 is fixedly connected to the inner side wall of the annular groove 302. The left and right sides of the connecting ring 305 are in contact with the inner side wall of the annular groove 302.

[0022] The bearing 2 here is a mature mechanical component in the prior art, and this application will not elaborate on its model or internal structure. The material of the second elastic pad 304 here is preferably rubber.

[0023] By setting a buffer mechanism 3 outside the bearing 2, multiple annular rings 303 are nested in the annular groove 302 on the inner sidewall of the annular frame 301 and connected by a second elastic pad 304. When the high-speed motor vibrates during operation, the annular rings 303 can generate relative displacement within the annular groove 302. The elastic deformation of the second elastic pad 304 can effectively absorb and disperse vibration energy, greatly reducing the direct impact of vibration on the bearing 2. This allows the two bearings 2 to work together efficiently to resist vibration under complex working conditions, significantly suppressing vibration transmission, effectively improving the stability of motor operation, and thus extending the service life of the motor.

[0024] The output end of the rotor shaft 1 is provided with a buffer hole 4. Multiple sliding plates 5 are slidably connected to the inner wall of the buffer hole 4. A first elastic pad 6 is fixedly connected between each of the multiple sliding plates 5. The left side of the leftmost sliding plate 5 is fixedly connected to the inner wall of the buffer hole 4. A sliding rod 7 is fixedly connected to the right side of the rightmost sliding plate 5. The outer surface of the sliding rod 7 is slidably connected to the inner wall of the buffer hole 4. A sleeve 8 is slidably connected to the right side of the outer surface of the rotor shaft 1. The inner wall of the sleeve 8 is fixedly connected to the right end of the sliding rod 7.

[0025] The material of the first elastic pad 6 here is preferably rubber.

[0026] By setting a buffer structure consisting of a sliding plate 5, a first elastic pad 6, a sliding rod 7, and a sleeve 8 at the output end of the rotor shaft 1, multiple sliding plates 5 are connected by the first elastic pad 6, and the sliding rod 7 cooperates with the sleeve 8. When the motor generates axial vibration, the sliding plate 5 can slide in the buffer hole 4, and the first elastic pad 6 undergoes elastic deformation to buffer and absorb the axial vibration, further enhancing the vibration resistance of the entire assembly. This ensures that the rotor shaft 1 is positioned more accurately when the motor is running at high speed, reduces component wear and precision degradation caused by vibration, and improves the overall performance of the motor.

[0027] Working Principle: During the operation of the high-speed motor, the rotor shaft 1 drives the bearing 2 to rotate at high speed, inevitably generating vibration. When radial vibration occurs, the buffer mechanism 3 outside the bearing 2 comes into play. The annular frame 301 remains stationary, and the multiple annular rings 303 in the annular groove 302 will slide and deform relative to each other due to the elastic characteristics of the second elastic pad 304 under the action of vibration. This deformation can convert vibration energy into elastic potential energy, thereby weakening the vibration intensity and reducing the transmission of vibration to other parts of the motor. When axial vibration occurs, the buffer structure at the output end of the rotor shaft 1 starts to work. The sliding plate 5 slides axially in the buffer hole 4, and the first elastic pad 6 is compressed or stretched between the sliding plates 5, absorbing the energy generated by axial vibration by its own elastic deformation. At the same time, the sliding cooperation between the sliding rod 7 and the sleeve 8 also plays a certain role in limiting and buffering axial displacement. The dual anti-vibration structures work together to effectively reduce the vibration during motor operation and ensure stable and efficient operation of the motor.
