Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a motor shaft structure and a motor. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. The motor contains a shaft, which is connected to the shaft of the equipment to drive the equipment to rotate.

[0003] When a motor is working, it drives the equipment shaft to rotate through its shaft. Due to the influence of the operating environment of the equipment or motor, the rotation angle between the motor shaft and the equipment shaft may be misaligned. When the misalignment during rotation suddenly becomes large, it can easily lead to damage to the motor shaft and reduce its service life. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that during the operation of a motor, the rotation angle between the motor shaft and the equipment shaft may be skewed due to the influence of the operating environment of the equipment or motor. When the skewed angle suddenly becomes large, it can easily lead to damage to the motor shaft and reduce its service life. Therefore, this utility model proposes a motor shaft structure and a motor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a motor shaft structure and a motor, including a shaft rod, one end of which is provided with a buffer device to buffer the deviation that occurs when the shaft rod is connected to the equipment shaft during rotation. The buffer device includes a disc and a collar. One side of the disc is fixedly connected to one end of the shaft rod. A conical block is fixedly connected to the end of the disc away from the shaft rod. Several L-shaped rods are fixedly connected to the outer circumference of the collar. A hollow rubber block is fixedly connected to one end of each L-shaped rod. The hollow rubber block is fixedly connected to the outer surface of the shaft rod by adhesive bonding. Several mounting holes are provided on one side of the collar.

[0006] Furthermore, a slide rod is slidably connected to the inner wall of the end of the L-shaped rod away from the hollow rubber block, and an abutment block is fixedly connected to one end of the slide rod. The abutment block is attached to the outer surface of the conical block, and a spring is provided at the end of the slide rod away from the abutment block. The two ends of the spring are fixedly connected to one end of the inner wall of the L-shaped rod and one end of the slide rod, respectively, by setting a collar.

[0007] Furthermore, two grooves are provided at one end of the L-shaped rod near the slide bar, and two sliders are fixedly connected to the outer surface of the slide bar, with the sliders sliding on the inner wall of the grooves.

[0008] Furthermore, a reinforcing block is fixedly connected to one side of the slider, and the end of the reinforcing block away from the slider is fixedly connected to the outer surface of the slider rod.

[0009] Furthermore, one end of the conical block is provided with a sealing assembly that can further seal the outside of the collar.

[0010] Furthermore, the sealing assembly includes a sealing sheet, a bolt is inserted into the inner wall of the sealing sheet, and a threaded hole is provided on one side of the conical block, with the bolt threadedly connected to the threaded hole.

[0011] Furthermore, a circular groove is provided on one side of the sealing sheet to accommodate the bolt head.

[0012] Furthermore, it also includes an electric motor, comprising a housing, with a shaft rotating inside the housing.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, a buffer device is installed. A circular block is fixed at one end of the shaft and connected to the equipment shaft via a collar. When the shaft drives the equipment shaft to rotate and the angle of the equipment shaft deviates, the collar will move to the deviated side, compressing the hollow rubber block and the internal spring at the L-shaped rod end away from the direction of collar movement. This allows the collar to follow the equipment shaft with a small degree of angular deviation and movement, without directly torturing the shaft, reducing damage to the shaft, and thus extending the service life of the shaft during operation.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0018] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] In this embodiment: like Figures 1-2 As shown, a motor shaft structure and a motor are disclosed, including a shaft 1. One end of the shaft 1 is provided with a buffer device 2 to buffer the deflection that occurs when the shaft 1 is connected to the equipment shaft during rotation. The buffer device 2 includes a disc 21 and a collar 23. One side of the disc 21 is fixedly connected to one end of the shaft 1, and a conical block 22 is fixedly connected to the end of the disc 21 away from the shaft 1. Several L-shaped rods 24 are fixedly connected to the outer circumference of the collar 23. A hollow rubber block 25 is fixedly connected to one end of the L-shaped rod 24. The hollow rubber block 25 is fixedly connected to the outer surface of the shaft 1 by adhesive bonding. Several mounting holes are opened on one side of the collar 23. When connecting the motor shaft 1 to the equipment shaft, the flange at one end of the equipment shaft 1 is connected to the threaded hole on the collar 23. The equipment shaft and the shaft 1 are connected through the collar 23 and the disc 21.

[0020] Reference Figures 1-4As shown in this embodiment: a slide rod 26 is slidably connected to the inner wall of the end of the L-shaped rod 24 away from the hollow rubber block 25. An abutment block 27 is fixedly connected to one end of the slide rod 26, and the abutment block 27 fits against the outer surface of the conical block 22. A spring 212 is provided at the end of the slide rod 26 away from the abutment block 27. The two ends of the spring 212 are fixedly connected to one end of the inner wall of the L-shaped rod 24 and one end of the slide rod 26, respectively. A collar 23 is provided, and the disc 21 and the collar 23... After shaft 1 is connected to the equipment shaft, if the angle between the equipment shaft and shaft 1 deviates during the rotation driven by the motor, the equipment shaft will drive the collar 23 to move to the deviated side. This will cause the hollow rubber block 25 at one end of the L-shaped rod 24, which is away from the direction of movement of the collar 23, to be compressed and folded. At the same time, the contact between the abutment block 27 and the conical block 22 will cause the sliding rod 26 at one end of the L-shaped rod 24 to slide on the inner wall of the L-shaped rod 24 and be compressed. Spring 212 allows the collar 23 to follow the equipment shaft with a small degree of angular deflection and movement, without directly torturing the shaft 1. When the deflection angle is restored, the hollow rubber block 25 returns to its original shape, and the spring 212 compressed inside the L-shaped rod 24 returns to its original shape, pushing the slide rod 26 outward to return the collar 23 to its original position. By setting up the buffer device 2, fixing a round block at one end of the shaft 1, and connecting it to the equipment shaft through the collar 23, when the shaft 1 drives the equipment shaft to rotate and the angle of the equipment shaft deflects, it will drive the collar 23 to move to the deflected side, compressing the hollow rubber block 25 and the internal spring 212 at the end of the L-shaped rod 24 away from the direction of movement of the collar 23. This allows the collar 23 to follow the equipment shaft with a small degree of angular deflection and movement, without directly torturing the shaft 1, reducing damage to the shaft 1, and thus increasing the service life of the shaft 1 during operation.

[0021] Reference Figures 2-4 As shown in this embodiment: two grooves 29 are provided at one end of the L-shaped rod 24 near the slide rod 26. Two sliders 210 are fixedly connected to the outer surface of the slide rod 26. The sliders 210 slide on the inner wall of the groove 29. When the collar 23 moves, the two sliders 210 on the outer surface of the slide rod 26 will move inside the two grooves 29 on the outer surface of the L-shaped rod 24, further restricting the angle between the slide rod 26 and the L-shaped rod 24, making it less likely for the slide rod 26 to deviate. A reinforcing block 211 is fixedly connected to one side of the slider 210. The end of the reinforcing block 211 away from the slider 210 is fixedly connected to the outer surface of the slide rod 26. By setting the reinforcing block 211, the connection between the slider 210 and the slide rod 26 can be supported and reinforced, preventing the movement of the slide rod 26 from causing one side of the slider 210 to contact the inner wall of the groove 29, which would lead to loosening and breakage of the connection between the slider 210 and the slide rod 26.

[0022] Reference Figure 3 , Figure 6 and Figure 7 As shown in this embodiment: one end of the conical block 22 is provided with a sealing component 28 that can further seal the outside of the collar 23. The sealing component 28 includes a sealing plate 282, and a bolt 283 is inserted into the inner wall of the sealing plate 282. A threaded hole 281 is opened on one side of the conical block 22, and the bolt 283 is threadedly connected to the threaded hole 281. Before connecting the equipment shaft to one side of the collar 23, the sealing plate 282 can be attached to one end of the conical block 22, and then the bolt 283 is inserted into the threaded hole 281 through the outer surface of the sealing plate 282. The bolt 283 is rotated to make the bolt 283 threaded into the threaded hole 281. The bolt 283 is connected to the threaded hole 281 and fully inserted into it. The sealing plate 282 is fixed to one end of the tapered block 22 and the collar 23. The sealing plate 282 further seals the connection between the collar 23 and the equipment shaft flange and the outside of the tapered block 22, so as to prevent oil and dust from entering the collar 23 as much as possible. A circular groove 284 is provided on one side of the sealing plate 282. The circular groove 284 is used to accommodate the head of the bolt 283. By providing a circular groove 284 on one side of the sealing plate 282, the head of the bolt 283 can fit into the sealing plate 282 after entering the threaded hole 281 and will not protrude from the surface of the collar 23.

[0023] Reference Figures 1-2 As shown, an electric motor includes the aforementioned motor shaft structure and a housing 3, with the shaft 1 rotating inside the housing 3.

[0024] Working principle: When connecting the motor shaft 1 to the equipment shaft, the sealing plate 282 is attached to one end of the tapered block 22. Then, a bolt 283 is inserted through the outer surface of the sealing plate 282 into the threaded hole 281. Rotating the bolt 283 causes it to be threaded into the threaded hole 281 and fully inserted inside. The sealing plate 282 is then fixed to one end of the tapered block 22 and the collar 23. The sealing plate 282 further seals the connection between the collar 23 and the equipment shaft flange, as well as the outer side of the tapered block 22. Subsequently, the flange at one end of the equipment shaft is connected to the collar 23. The equipment shaft and shaft 1 are connected through the collar 23 and the disc 21. During the operation of the motor driving the shaft 1 to rotate, if the equipment shaft... When the angle between the collar and shaft 1 is deflected, the equipment shaft will drive the collar 23 to move to the deflected side. This causes the hollow rubber block 25 at one end of the L-shaped rod 24, which is away from the direction of movement of the collar 23, to be compressed and folded. At the same time, the contact between the abutment block 27 and the conical block 22 will cause the slide rod 26 at one end of the L-shaped rod 24 to slide on the inner wall of the L-shaped rod 24 and compress the spring 212. This allows the collar 23 to follow the equipment shaft with a small degree of angular deflection and movement without directly torturing the shaft 1. When the deflection angle is restored, the hollow rubber block 25 will return to its original shape. At the same time, the spring 212 compressed inside the L-shaped rod 24 will return to its original shape and push the slide rod 26 outward to return the collar 23 to its original position.
