[0031] like Figure 1-3As shown in the figure, an energy-saving motor based on a low-friction rotor includes a motor base 1 and a motor body 2. The motor body 2 is connected to the motor base 1. A motor cavity 3 is provided on the motor body 2. The inner wall of the motor cavity 3 is fixedly connected with a deep groove ball bearing 5, a connecting piece 8, a fixing piece 47, a transmission column 11, a fixing plate 15 and a liquid tank 23.

When the two second conductive springs 17 are electrically connected, the motor switch control device is energized, and energizing the motor switch control device de-energizes the energy-saving motor. The motor base 1 is fixedly attached to the location where the energy-saving motor is required. The deep groove ball bearing 5 operates by achieving relative motion between the rotating shaft 4 and the bearing seat through the rolling of the rolling elements between the inner and outer rings. This rolling friction method significantly reduces friction compared to sliding friction. The contact point of rolling friction constantly changes, the friction is locally concentrated, and the contact time is short, resulting in low friction energy loss, thereby effectively reducing the friction of the rotating shaft 4.

[0033] like Figure 1-3 As shown in the figure, according to an optional embodiment of the present invention, a liquid filling hole is opened on the deep groove ball bearing 5, and the liquid filling hole is connected to the liquid replenishing channel 26. The liquid filling hole is used to add lubricating fluid 25, thereby reducing the friction between the rotating shaft 4 and the inner wall of the deep groove ball bearing 5, thereby eliminating abnormal vibration.

[0034] like Figure 1-5 As shown in the figure, according to an optional embodiment of the present invention, a connecting block 44 is fixedly connected to the outer wall of the motor body 2, a connecting hole 45 is opened on the connecting block 44, and a thread groove 46 is opened on the top wall of the motor base 1.

[0035] like Figure 1-5 As shown in the figure, according to an optional embodiment of the present invention, a fourth worm gear 51 is fixedly connected to the rotating shaft 4, a reducer 48 and an electromagnet 32 ​​are fixedly connected to the inner wall of the motor cavity 3, a third worm gear 49 is fixedly connected to the input shaft of the reducer 48, a fourth spur gear 50 is fixedly connected to the output shaft of the reducer 48, the third worm gear 49 and the fourth worm gear 51 are meshed, a moving table 28 is slidably connected to the inner wall of the motor cavity 3, a second spur gear 29 is rotatably connected to the moving table 28, a permanent magnet 30 is fixed to the moving table 28, the moving table 28 is connected to the inner wall of the motor cavity 3 through a second elastic member 31, a rotating rod 33 and two worms 36 are rotatably connected to the inner wall of the motor cavity 3, both ends of the worm 36 extend to the outside of the motor body 2, a third spur gear 35 and two first worm gears 34 are fixedly connected to the rotating rod 33, and the two first worm gears 34 are respectively meshed with the two worms 36;

[0036] Four mounting blocks 37 are detachably connected to the outer wall of the motor body 2. A second worm gear 38 is rotatably connected to the bottom wall of the mounting block 37. An extension rod 39 is fixedly connected to the bottom wall of the second worm gear 38. A rod slot 40 is defined at the lower end of the extension rod 39. A screwdriver body 41 is slidably connected to the inner wall of the rod slot 40. The upper end of the screwdriver body 41 is connected to the top wall of the rod slot 40 via a third elastic member 42. The screwdriver body 41 extends below the extension rod 39, and the screwdriver body 41 abuts against the inner wall of the head groove on the bolt 43.

[0037] Two of the second worm wheels 38 are respectively engaged with one of the worms 36 , and the other two second worm wheels 38 are respectively engaged with the other worm 36 ;

[0038] Two first conductive springs 16 are fixedly connected to the fixing plate 15 . The two first conductive springs 16 are electrically connected to the electromagnet 32 ​​, respectively. When the two first conductive springs 16 are electrically connected, the electromagnet 32 ​​is energized.

[0039] The blade of the screwdriver body 41 can be set to a cross blade, a flat blade or other shapes, mainly to adapt to the shape of the head groove on the bolt 43.

[0040] The four mounting blocks 37 are detachable so that they will not cause obstruction when other screwdrivers are used to tighten the bolts 43 in the early stage. After the other screwdrivers tighten the bolts 43 , the four mounting blocks 37 are installed on the motor body 2 .

[0041] According to an optional embodiment of the present invention, the reducer 48 is a planetary gear reduction device.

[0042] According to an optional embodiment of the present invention, a heat dissipation blade is fixedly connected to the rotating shaft 4. The heat dissipation blade is used to drive heat away from the interior of the energy-saving motor.

[0043] According to an optional embodiment of the present invention, a guide groove is provided on the inner wall of the motor cavity 3 , and the vibration detection block 6 is slidably connected to the inner wall of the guide groove.

[0044] According to an optional embodiment of the present invention, the conductive rack 14 , the first conductive spring piece 16 and the second conductive spring piece 17 are all made of copper, which has good electrical conductivity and is used as a conductive component.

[0045] According to an optional embodiment of the present invention, the rotating shaft 4 is coated with a lubricating layer, which can reduce the friction between the rotating shaft 4 and other components, thereby achieving a low-friction function.

[0046] According to an optional embodiment of the present invention, the lubricating layer is a graphite coating.

[0047] Implementation process:

[0048] When the energy-saving motor operates normally, the vibration amplitude is not large, the left-right displacement amplitude of the vibration detection block 6 is very small, and the vibration detection block 6 will not collide with the inflatable ball 9.

[0049] When the energy-saving motor vibrates abnormally, the vibration amplitude becomes larger, and the vibration detection block 6 has a larger displacement amplitude to the left and right under the action of inertia. The vibration detection block 6 will reciprocate and squeeze the inflatable ball 9. The inflatable ball 9 fills the piston channel 12 with air through the air pipe 10. The air pushes the piston body 13 and the conductive rack 14 to move upward. The conductive rack 14 needs to move up a distance before it meshes with the first spur gear 18. The upward movement of the conductive rack 14 drives the first spur gear 18 and the threaded rod 19 to rotate. Since the threaded rod 19 is threadedly connected to the inner wall of the threaded hole 21, the threaded rod The rotation of 19 will drive the liquid-blocking plate 20 to gradually move to the right. When the perforation 22 and the fluid replenishing channel 26 are connected, the lubricating liquid 25 will pass through the fluid replenishing channel 26 and fall into the fluid filling hole of the deep groove ball bearing 5, thereby adding the lubricating liquid 25 between the rotating shaft 4 and the deep groove ball bearing 5. If the abnormal vibration is caused by the increased friction between the rotating shaft 4 and the deep groove ball bearing 5, the abnormal vibration will be eliminated after adding the lubricating liquid 25, the vibration detection block 6 will no longer squeeze the inflatable ball 9, the conductive rack 14 will no longer move up, and the conductive rack 14 will not offset the second conductive spring piece 17.

[0050] There is a certain distance between the conductive rack 14 and the first spur gear 18, so that the perforation 22 can connect the fluid replenishing channel 26 with the perforation 22 to add lubricating fluid 25 only after the energy-saving motor vibrates abnormally for a period of time, thereby preventing misjudgment caused by the energy-saving motor occasionally vibrating with excessive amplitude for a short period of time, thereby improving the accuracy of automatic detection.

[0051] The horizontal movement of the liquid blocking plate 20 is driven by the rotation of the threaded rod 19 , which can prevent the liquid blocking plate 20 from being displaced due to vibration of the energy-saving motor, thereby preventing the lubricating liquid 25 from being added incorrectly.

[0052] If the abnormal vibration is not eliminated after adding the lubricating fluid 25, the conductive rack 14 continues to move upward and counteracts the two first conductive springs 16. The two first conductive springs 16 are electrically connected, so that the electromagnet 32 ​​is energized to generate a magnetic repulsive force. The permanent magnet 30 overcomes the elastic force of the second elastic member 31 and moves leftward after being subjected to the magnetic repulsive force of the electromagnet 32. The second spur gear 29 moves leftward to mesh with the fourth spur gear 50 and the third spur gear 35. The rotation of the rotating shaft 4 drives the fourth worm gear 51 and the third worm gear 49 to rotate. The third worm gear 49 is decelerated by the reducer 48 to rotate. The fourth spur gear 50, the second spur gear 29, the third spur gear 35, the first worm gear 34, the rotating rod 33, the worm 36, the second worm gear 38, the extension rod 39, and the screwdriver body 41 rotate slowly, and the screwdriver body 41 drives the bolt 43 to rotate and tighten. Under the elastic force of the third elastic member 42, the screwdriver body 41 rotates and moves downward, thereby maintaining contact with the inner wall of the groove on the head of the descending bolt 43, thereby strengthening the connection strength of the connecting block 44 to the motor base 1 and preventing abnormal vibration caused by loose connection of the energy-saving motor. If the energy-saving motor causes abnormal vibration due to loose connection, the abnormal vibration will be eliminated after the bolt 43 is tightened, and the conductive rack 14 will not continue to move upward. The electromagnet 32 ​​will automatically power off soon after being energized. After the permanent magnet 30 loses the magnetic repulsion of the electromagnet 32, it will move to the right and reset under the elastic force of the second elastic member 31. The second spur gear 29 will disengage from the fourth spur gear 50 and the third spur gear 35 to prevent the bolt 43 from rotating too much and causing damage. The automatic power-off function of the electromagnet 32 ​​can be achieved through existing technology and is not limited here.

[0053] If the abnormal vibration is not eliminated after tightening the bolt 43, the conductive rack 14 continues to move upward and counteracts the two second conductive springs 17. When the motor switch control device is energized, the energy-saving motor will be powered off and stop working, waiting for maintenance personnel to come for maintenance, to prevent the abnormal vibration from lasting too long and damaging the energy-saving motor components.

[0054] The present invention can automatically detect whether the energy-saving motor has abnormal vibration through the vibration detection block 6 in an energy-saving manner without the need for electricity. After detecting the abnormal vibration, the inertia generated by the vibration is used as a driving force to automatically add lubricating fluid 25 between the rotating shaft 4 and the deep groove ball bearing 5. The rotation of the rotating shaft 4 is used as a driving force to automatically tighten the four bolts 43, so as to automatically eliminate two of the causes with a higher probability of causing abnormal vibration. If the abnormal vibration still cannot be eliminated, the energy-saving motor will be automatically powered off to protect the components from damage and extend the service life of the energy-saving motor.

[0055] The components, modules, mechanisms and devices not described in detail in the present invention are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
