It uses an energized coil to generate a rotating magnetic field and acts on the rotor to form a magneto-electromotive force to rotate the torque. The electric motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines; the motor shaft is a cylindrical object that passes through the middle of the bearing or the middle of the wheel or the middle of the gear, but a small number of them are square. The shaft supports the rotating parts and rotates with them to transmit motion, torque or bending moment. The mechanical parts are generally in the shape of metal round rods. When the shaft contacts the transmission structure, a certain amount of friction will be generated. Appropriate lubricating oil needs to be added to reduce the friction coefficient of the side surface of the bearing, thereby increasing the service life of the bearing.

DETAILED DESCRIPTION

[0022] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] like Figure 1-Figure 10 As shown, the motor output shaft protection mechanism provided in this embodiment includes a motor body 1, and a monitoring module 2 is arranged on the outside of the output shaft of the motor body 1. The monitoring module 2 includes an oil storage box 4, an abutment structure 5, an oil delivery structure 7 and an oil discharge structure 8 installed on the mounting structure 3. The mounting structure 3 includes a mounting shell 301, and the mounting shell 301 is provided with a through hole 302, a mounting groove 303 and a sliding mouth 304; there are two mounting shells 301, and the two mounting shells 301 are bolted. An oil inlet hole is provided in the oil storage box 4. Specifically, one of the mounting shells 301 is installed with an oil delivery pipe connected to the oil inlet hole. The abutment structure 5 is located outside the mounting structure 3, and a first transmission structure 6 is installed between the abutment structure 5 and the oil storage box 4, and a second transmission structure 10 is installed between the abutment structure 5 and the oil delivery structure 7; as shown Figure 2-Figure 5 As shown, the abutment structure 5 includes a detachably mounted vertical plate 501 and an abutment block 503, the abutment block 503 is located outside the output shaft of the motor body 1, and a pressure pad 504 for monitoring the motor body 1 is installed inside the abutment block 503, and the abutment structure 5 drives the vertical plate 501 to reciprocate by using the vibration of the motor body 1 to fit with the abutment block 503. It should be noted that a guide structure for guiding the vertical plate 501 is installed on the outer surface of the mounting shell 301, so that it can move linearly and stably.

[0024] Specifically, Figure 4-Figure 6As shown, a screw rod 502 is fixed on the upper surface of the abutment block 503, and the screw rod 502 is threadedly connected to the vertical plate 501, the oil storage box 4 is fixed inside the mounting shell 301, and a stirring rod 41 extending to the outside of the mounting shell 301 is installed in the bearing inside the oil storage box 4, and the stirring rod 41 is connected to the first transmission structure 6 and stirs through the reciprocation of the abutment structure 5. In order to activate the lubricating oil in the oil storage box 4, the reciprocating motion of the abutment structure 5 is transmitted to the stirring rod 41 through the first transmission structure 6, so as to realize automatic stirring of the lubricating oil in the oil storage box 4. This helps to maintain the uniformity and fluidity of the lubricating oil, ensure that the motor is well lubricated, and reduce wear and failure.

[0025] like Figure 2-Figure 4 and Figure 6 As shown, the first transmission structure 6 includes a connecting block 601 fixed to the outer surface of the stirring rod 41 and a connecting plate 602 fixed to the top side of the vertical plate 501 and slidingly matched with the connecting block 601, a first connecting shaft 603 is fixed to the top side of the connecting plate 602, and the other end bearing of the first connecting shaft 603 is installed with a first roller 604 extending to the inside of the connecting block 601. Among them, a first slide groove 605 adapted to the first roller 604 is provided inside the connecting block 601, the abutment block 503 is arc-shaped, and a pressure monitoring sensor block is detachably installed inside the pressure pad 504. The abutment block 503 is located outside the output shaft of the motor body 1 and is equipped with a pressure pad 504, which can directly monitor the vibration and abnormal conditions of the motor. When the motor vibrates abnormally, the abutment block 503 will move accordingly, driving the vertical plate 501 to reciprocate through the screw 502, thereby quickly triggering the subsequent protection or monitoring mechanism. An extension plate 505 that can extend outside the abutment block 503 is slidably installed inside, and an adjustment rod 506 plugged with the extension plate 505 is installed inside the abutment block 503. After the extension plate 505 extends out from the inside of the abutment block 503, it is fixed by the adjustment rod 506, and the shape of the extension plate 505 is adapted to the abutment block 503. The design of the extension plate 505 and the adjustment rod 506 enables the abutment block 503 to be adjusted according to demand and vibration characteristics. Through the extension and fixation of the extension plate 505, it can be ensured that the abutment block 503 maintains good contact with the motor body 1, thereby improving the accuracy and reliability of vibration monitoring. It should be noted that the screw rod 502 is connected to the vertical plate 501. When the motor output shaft vibrates, the movement of the abutment block 503 is transmitted to the vertical plate 501 through the screw rod 502, so that the vertical plate 501 also reciprocates.

[0026] To achieve automatic oil delivery, Figure 3 , Figure 4 , Figure 7-Figure 9As shown, the oil delivery structure 7 includes a pump housing 701 and a valve tube 702 that are fixedly connected, wherein a diaphragm 703 is fixed inside the pump housing 701, and two valve plates 706 for cooperating with the agitation of the diaphragm 703 are elastically hingedly installed inside the valve tube 702, and the upper and lower ends of the valve tube 702 are fixedly connected with connecting tubes 707, and the pump housing 701 and the valve tube 702 are both fixed in the installation groove 303. Among them, the top connecting tube 707 is fixedly connected with the lower surface of the oil storage box 4, and the outer surface of the diaphragm 703 is fixed with a valve stem 704 extending from the outside of the pump housing 701, and the outer surface of the valve stem 704 is installed with a second connecting shaft 705 connected to the second transmission structure 10. In order to realize the linkage between the oil delivery structure 7 and the abutment structure 5, as shown in FIG. Figure 4 and Figure 5 As shown, the second transmission structure 10 includes a slide 1001 fixed to the outer surface of the vertical plate 501, a second slide groove 1002 is provided inside the slide 1001, and the second slide groove 1002 is inclined, a second roller 1003 is rollingly connected inside the second slide groove 1002, one end of the second connecting shaft 705 away from the valve stem 704 is connected to the bearing of the second roller 1003, and the slide 1001 passes through the slide 304 and extends to the inside of the mounting shell 301. Through the design of the second transmission structure 10, the automatic linkage between the abutment structure 5 and the oil delivery structure 7 is realized. When the motor body 1 vibrates, the vertical plate 501 of the abutment structure 5 will reciprocate, and this movement is finally converted into the agitation of the diaphragm 703 through the transmission of the slide 1001, the second slide groove 1002 and the second roller 1003. This process does not require manual intervention, realizes the automatic delivery of lubricating oil, and improves the automation degree and work efficiency of the device.

[0027] In addition, by adjusting the parameters of the second transmission structure 10 (such as the inclination angle of the second slide groove 1002, the size of the second roller 1003, etc.), it can adapt to motor output shaft protection mechanisms of different models and specifications. This design makes the device highly adaptable and flexible, and can be applied to a variety of different motor protection scenarios.

[0028] like Figure 7-Figure 10 As shown, the oil drainage structure 8 includes a material receiving box 801 fixed on the inner wall of the mounting groove 303 and an oil storage cotton 802 detachably mounted inside the material receiving box 801. A docking tube 708 is fixedly connected between the bottom connecting tube 707 and the oil drainage structure 8. An oil drainage hole 803 connected to the through hole 302 is provided inside the material receiving box 801. A linkage structure 9 is installed between the abutment structure 5 and the oil drainage structure 8. The oil drainage structure 8 realizes oil drainage through the reciprocating motion of the linkage structure 9 and the abutment structure 5. The reciprocating motion of the abutment structure 5 is also transmitted to the oil drainage structure 8 through the linkage structure 9, so as to realize automatic drainage of the lubricating oil. This helps to regularly replace or update the lubricating oil, keep the motor clean and run efficiently, and reduce maintenance costs and workload. Figure 3 , Fig. 9 and Fig.10 As shown, the linkage structure 9 includes a connecting arm 901 fixed to the outer surface of the vertical plate 501 and extending into the interior of the mounting shell 301 through the sliding opening 304, a collar 902 welded to the other end of the connecting arm 901 and sleeved on the outer surface of the bottom connecting pipe 707, and a guide member fixed to the top side of the docking pipe 708 and extending through the connecting arm 901, and a shock-guide pad 903 is fixed to the inner side of the collar 902; specifically, the linkage structure 9 also includes a push rod 906 fixed to the lower surface of the connecting arm 901 and extending into the interior of the receiving box 801, and a pressure block 907 located above the oil storage cotton 802 is fixed to the bottom end of the push rod 906.

[0029] like Fig. 9 and Fig.10 As shown, the guide member includes a guide rod 904 and a spring 905 fixed to the top side of the butt joint 708, the top side of the spring 905 is fixed to the lower surface of the collar 902, and the guide rod 904 runs through the interior of the connecting arm 901. There are two guide members, and the two guide members are symmetrically arranged. The collar 902 is sleeved on the outer surface of the bottom connecting pipe 707 and contacts the connecting pipe 707 through the vibration guide pad 903. This design can effectively transmit the vibration of the abutment structure 5 while reducing friction and wear during the transmission process. The guide rod 904 runs through the connecting arm 901, providing a stable guiding effect for the connecting arm 901, ensuring the accuracy and reliability of the transmission. The addition of the spring 905 makes the linkage structure 9 have a certain buffering capacity, can absorb part of the vibration energy, and further improve the stability of the transmission.

[0030] like Figure 1-Figure 10 As shown, the principle of the motor output shaft protection mechanism provided in this embodiment is as follows: The motor body 1 is in a stationary or normal operating state, the abutment block 503 in the abutment structure 5 maintains a certain distance from the output shaft of the motor body 1 but does not contact or is in a slight contact state, but does not affect the normal operation of the motor, the oil storage box 4 is filled with lubricating oil, the stirring rod 41 is stationary, the diaphragm 703 of the oil delivery structure 7 is in the initial position, and the valve plate 706 in the valve tube 702 remains in a closed state; When the motor body 1 vibrates or is abnormal, the abutment block 503 is affected by the vibration and starts to reciprocate. The movement of the abutment block 503 is transmitted to the vertical plate 501 through the screw 502, so that the vertical plate 501 also reciprocates. The movement of the vertical plate 501 drives the first roller 604 to slide in the first slide groove 605 through the connecting plate 602 and the first connecting shaft 603. The sliding of the first roller 604 is converted into the reciprocating rotation movement of the stirring rod 41, so as to stir the lubricating oil in the oil storage box 4. The movement of the vertical plate 501 also drives the second roller 1003 to roll through the sliding seat 1001 and the second slide groove 1002. The rolling of the second roller 1003 drives the valve stem 704 to move up and down through the second connecting shaft 705, so that the diaphragm 703 agitates in the pump housing 701. The agitation of the diaphragm 703 causes the valve plate 706 in the valve pipe 702 to open and close alternately, so that the lubricating oil in the oil storage box 4 is pumped into the docking pipe 708 through the connecting pipe 707. The movement of the vertical plate 501 drives the collar 902 and the shock-guide pad 903 to move up and down through the connecting arm 901. The movement of the collar 902 is kept stable by the guide rod 904 and the spring 905, and is transmitted to the docking tube 708, but its main function is to link the push rod 906. The up and down movement of the push rod 906 drives the pressure block 907 to compress the oil storage cotton 802, squeeze the lubricating oil out of the oil storage cotton 802, and discharge it through the oil discharge hole 803. The squeezed lubricating oil is discharged from the material receiving box 801 through the oil discharge hole 803 to lubricate the motor body 1.

[0031] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.
