Detailed implementation manners

[0021] The implementation manners of the present utility model will be described below with reference to the drawings.

[0022] Embodiment 1

[0023] A motor for preventing axial center deviation, as Figures 1-3 shown, includes a motor 1, a rotating shaft 2, a connecting seat 21, a mounting seat 3, and a fixing assembly 4. Mounting seats 3 are fixedly connected to both the front and rear sides of the motor 1. The connecting seat 21 is fixedly connected to an external device. The rotating shaft 2 is rotatably connected to the left side of the connecting seat 21. A fixing assembly 4 is provided between the output shaft of the motor 1 and the rotating shaft 2.

[0024] As Figure 3 shown, the fixing assembly 4 includes a first fixing ring 41, a second fixing ring 42, a contact block 43, a card holder 44, and a spring 45. The right end of the output shaft of the motor 1 is fixedly connected to the first fixing ring 41. Contact blocks 43 are fixedly connected to both the upper and lower parts on the right side of the first fixing ring 41. The right part of the contact block 43 has an inclined surface. The left end of the rotating shaft 2 is fixedly connected to the second fixing ring 42. Card holders 44 are slidably connected to both the upper and lower sides inside the second fixing ring 42. Pairs of springs 45 are fixedly connected between the card holders 44 and the second fixing ring 42. The card holders 44 are in clamping fit with the contact blocks 43.

[0025] When a worker needs to dock the output shaft of the motor 1 with the rotating shaft 2 of an external device, the output shaft can be aligned with the rotating shaft 2 first, and then the motor 1 is moved in the direction close to the rotating shaft 2 and the second fixing ring 42, driving components such as the first fixing ring 41 and the contact block 43 to move in the direction close to the second fixing ring 42 and the clamping frame 44. When the inclined surface of the contact block 43 moves to contact and squeeze the clamping frame 44, the upper and lower clamping frames 44 will move away from each other, and the spring 45 will be compressed immediately. When the inclined surface of the contact block 43 separates from the clamping frame 44, the upper and lower clamping frames 44 will move towards each other and reset under the action of the spring 45, and thus quickly and stably clamp and align the output shaft of the motor 1 with the rotating shaft 2 of the external device, avoiding the situation of axial offset due to inaccurate and insecure docking of the two. Finally, the motor 1 is fixed at an appropriate position through screws and the mounting seat 3. When the worker needs to separate the output shaft of the motor 1 from the rotating shaft 2, just pull the two clamping frames 44 backward, and then move the motor 1 in the direction away from the rotating shaft 2 until they are separated.

[0026] Embodiment 2

[0027] On the basis of Embodiment 1, as Figure 1 and Figure 4 shown, it further includes a guide rod 31, a first slider 5, a bolt 6, a limit ring 7, a connecting plate 8 and an induction alarm 9. Guide rods 31 are fixedly connected to both the front and rear parts on the right side of the motor 1, and guide rods 31 are fixedly connected to both the front and rear parts on the left side of the connecting seat 21. The first slider 5 is slidably connected to the outside of the guide rod 31. Bolts 6 are threadedly connected to the mutually remote sides of adjacent first sliders 5. A limit ring 7 is fixedly connected between adjacent first sliders 5. A connecting plate 8 is fixedly connected between adjacent first sliders 5. An induction alarm 9 is fixedly connected to the top of the connecting plate 8.

[0028] As Figure 1 and Figure 4 shown, the limit ring 7 is made of rubber material.

[0029] To prevent the situation of axial offset when the motor 1 and the rotating shaft 2 are operating, the worker can adjust the first slider 5, the limit ring 7 and the induction alarm 9 left and right according to the required detection accuracy. And the closer the two limit rings 7 and the induction alarm 9 are, the higher the detection accuracy. After adjustment, rotate the bolt 6 until the bolt 6 passes through the first slider 5 and contacts and squeezes the guide rod 31, so as to fix the positions of components such as the first slider 5, the limit ring 7 and the induction alarm 9. When the output shaft of the motor 1 and the rotating shaft 2 are offset, they will contact and squeeze the adjacent limit ring 7, and the limit ring 7 will deform immediately to contact and trigger the induction alarm 9, so as to remind the worker to shut down the motor 1 and perform maintenance or replacement.

[0030] Embodiment 3

[0031] On the basis of Embodiment 2, asFigure 4 and Figure 5 As shown in Figure 5 , it further includes a guide rail 11, a second slider 12, a storage bottle 13 and a stopper 14. Guide rails 11 are fixedly connected to both the front and rear parts on the right side of the motor 1. A second slider 12 is slidably connected between the paired guide rails 11. A storage bottle 13 is fixedly connected to the middle of the second slider 12. A stopper 14 is slidably connected to the top of the storage bottle 13.

[0032] As Figure 5 shown in Figure 5 , the storage bottle 13 is made of a flexible material, and lubricating oil is stored in the storage bottle 13.

[0033] During the long-term operation of the motor 1, the worker can move the second slider 12 and the storage bottle 13 along the guide rail 11 to a suitable position, and then squeeze the storage bottle 13 to spray the lubricating oil in the storage bottle 13 onto the corresponding position of the output shaft of the motor 1, so as to reduce the friction between the motor 1 and the output shaft, and also take away part of the heat of the output shaft through the lubricating oil to prevent the motor 1 from overheating. After the lubricating oil is used up, just open the stopper 14 to add it.

[0034] Although the present disclosure has been described only with respect to a limited number of embodiments, those skilled in the art who benefit from the present disclosure will understand that various other embodiments can be designed without departing from the scope of the present invention.
