[0031] Such as Figures 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. Deep groove ball bearings 5, connecting pieces 8, fixing pieces 47, transmission columns 11, fixing plates 15, and liquid tanks 23 are fixedly connected to the inner wall of the motor cavity 3.

This way of rolling friction, compared with sliding friction, greatly reduces the frictional force. The contact points of rolling friction are constantly changing, the frictional force is concentrated locally and the contact time is short, and the frictional energy loss is small, thus effectively reducing the frictional force of the rotating shaft 4.

The liquid adding hole is used to add the lubricating liquid 25, thereby reducing the frictional force between the rotating shaft 4 and the inner wall of the deep groove ball bearing 5, and thus eliminating abnormal vibration.

[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 groove 40 is opened at the lower end of the extension rod 39, a screwdriver body 41 is slidably connected to the inner wall of the rod groove 40, the upper end of the screwdriver body 41 is connected to the top wall of the rod groove 40 through 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 gears 38 respectively mesh with one of the worm shafts 36, and the other two second worm gears 38 respectively mesh with the other worm shaft 36;

[0038] Two first conductive elastic sheets 16 are fixedly connected to the fixing plate 15, the two first conductive elastic sheets 16 are respectively electrically connected to the electromagnet 32, and when the two first conductive elastic sheets 16 are electrically connected, the electromagnet 32 is energized.

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

[0040] The four mounting blocks 37 are detachable, so as not to cause obstruction to the mounting blocks 37 when using other screwdrivers to tighten the bolt 43 in the early stage, and the four mounting blocks 37 are installed on the motor body 2 after other screwdrivers tighten the bolt 43.

[0041] In an alternative embodiment according to the present invention, the speed reducer 48 is a planetary gear reduction device.

[0042] In an alternative embodiment according to the present invention, a heat dissipation fan blade is fixedly connected to the rotating shaft 4. The heat dissipation fan blade is used to drive heat away from the inside of the energy-saving motor.

[0043] In an alternative embodiment of the present invention, a guiding 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 guiding groove.

[0044] In an alternative embodiment of the present invention, the conductive rack 14, the first conductive elastic sheet 16, and the second conductive elastic sheet 17 are all made of copper, which has good electrical conductivity and is used as a conductive component.

[0045] In an alternative embodiment of the present invention, a lubricating layer is coated on the rotating shaft 4, and the lubricating layer can reduce the friction between the rotating shaft 4 and other components, thereby realizing the low-friction function.

[0046] In an alternative embodiment of the present invention, the lubricating layer is a graphite coating.

[0047] Implementation process:

[0048] When the energy-saving motor is running normally, the vibration amplitude is small, the left and right displacement amplitude of the vibration detection block 6 is very small, and the vibration detection block 6 will not abut against the balloon 9.

[0049] When the energy-saving motor has abnormal vibration, the vibration amplitude becomes larger, the left and right displacement amplitude of the vibration detection block 6 is larger under the action of inertia, the vibration detection block 6 will reciprocally squeeze the balloon 9, and the balloon 9 will fill 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 upward a certain 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 rotation of the threaded rod 19 will drive the liquid blocking piece 20 to gradually move to the right. When the through hole 22 communicates with the liquid replenishing channel 26, the lubricating liquid 25 will pass through the liquid replenishing channel 26 and fall into the liquid adding hole of the deep groove ball bearing 5, so as to add 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 balloon 9, the conductive rack 14 will no longer move upward, and the conductive rack 14 will not abut against the second conductive elastic sheet 17.

[0050] There is a certain distance between the conductive rack 14 and the first spur gear 18, which can make the through hole 22 communicate with the liquid replenishing channel 26 to add the lubricating liquid 25 after the energy-saving motor has abnormal vibration for a period of time, preventing misjudgment when the energy-saving motor occasionally has a large vibration amplitude in a short time and improving the accuracy of automatic detection.

[0051] The rotation of the threaded rod 19 drives the horizontal movement of the liquid blocking piece 20, which can prevent the displacement of the liquid blocking piece 20 caused by the vibration of the energy-saving motor, thereby causing incorrect addition of the lubricating liquid 25.

[0052] If the abnormal vibration is not eliminated after adding the lubricating fluid 25, the conductive rack 14 continues to move upward and abuts against the two first conductive elastic pieces 16. The two first conductive elastic pieces 16 are electrically connected, so that the electromagnet 32 is energized to generate a magnetic repulsive force. After the permanent magnet 30 is subjected to the magnetic repulsive force of the electromagnet 32, it moves leftward against the elastic force of the second elastic member 31. 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. After the speed reduction of the third worm gear 49 by the speed reducer 48, 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. The screwdriver body 41 will drive the bolt 43 to rotate and tighten. The screwdriver body 41 moves downward while rotating under the elastic force of the third elastic member 42, so as to keep abutting against the inner wall of the upper head groove of the descending bolt 43, thereby strengthening the connection strength between the connecting block 44 and the motor base 1 and preventing abnormal vibration caused by loose connection of the energy-saving motor. If the energy-saving motor has 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 cut off the power soon after being energized. After the permanent magnet 30 loses the magnetic repulsive force of the electromagnet 32, it will move rightward and reset under the elastic force of the second elastic member 31. The second spur gear 29 disengages from the fourth spur gear 50 and the third spur gear 35 to prevent the bolt 43 from being damaged due to excessive rotation. The automatic power-off function of the electromagnet 32 can be realized by existing technologies 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 abuts against the two second conductive elastic pieces 17. The energization of the motor switch control device will cut off the power supply of the energy-saving motor and stop it from working, waiting for the maintenance personnel to come for maintenance to prevent the abnormal vibration from damaging the components of the energy-saving motor for too long.

[0054] The present invention can automatically and energy-efficiently detect whether there is abnormal vibration in the energy-saving motor through the vibration detection block 6 without the need for electricity. After detecting the abnormal vibration, the inertia generated by the vibration is used as the driving force to automatically add the lubricating fluid 25 between the rotating shaft 4 and the deep groove ball bearing 5, and the rotation of the rotating shaft 4 is used as the driving force to automatically tighten the four bolts 43, so as to automatically eliminate two of the reasons that are more likely to cause 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 whose structures are not described in detail in the present invention are all common standard parts or parts known to those skilled in the art. Their structures and principles can all be known by those skilled in the art through technical manuals or by 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 limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
