Description

Technical Field

[0001] This utility model relates to the field of motor bearing maintenance technology, specifically to a quantitative automatic lubrication device for motor bearings. Background Technology

[0002] Motor bearings are mechanical components installed between the motor rotor and stator to support the rotor, reduce friction during rotation, and ensure smooth and efficient operation. They typically consist of an inner ring, an outer ring, rolling elements (such as steel balls or rollers), and a cage. The inner ring fits tightly to the motor rotor shaft and rotates with the rotor; the outer ring is fixed to the motor end cover or housing; the rolling elements roll between the raceways of the inner and outer rings, achieving low-friction rotation; the cage's function is to evenly separate the rolling elements, preventing them from colliding and rubbing against each other.

[0003] However, in practical applications, traditional motor bearing lubrication methods primarily rely on manual, periodic lubrication, which has several drawbacks. Firstly, manual lubrication makes it difficult to precisely control the amount of grease added; over-lubrication can lead to grease leakage, waste, and environmental pollution, while under-lubrication fails to meet the bearing's lubrication needs, accelerating wear, reducing motor efficiency, and even causing motor malfunctions. Secondly, manual lubrication requires scheduled, dedicated personnel, increasing labor costs and increasing the risk of delayed lubrication due to human error, thus affecting the normal operation of the motor. Utility Model Content

[0004] The purpose of this invention is to provide a quantitative automatic lubrication device for motor bearings, addressing the shortcomings of traditional manual lubrication methods described in the background. Manual lubrication is difficult to control precisely; excessive lubrication leads to grease leakage, waste, and environmental pollution, while insufficient lubrication fails to meet bearing lubrication needs, accelerating wear, reducing motor efficiency, and even causing motor malfunctions. Furthermore, manual lubrication requires regular operation by designated personnel, increasing labor costs and increasing the risk of delayed lubrication due to human error, thus affecting normal motor operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including a motor body, an oil storage tank fixedly installed on the outside of the motor body, an oil outlet fixedly connected to the lower end of the oil storage tank, a metering refueling pump fixedly installed on the lower outside of the oil storage tank, and a first refueling connection port fixedly connected to the lower outlet of the metering refueling pump;

[0006] A mounting ring is fixedly installed at the front bearing of the motor body. A rotating ring is rotatably connected to the inner side wall of the mounting ring via a rotating shaft. A semi-transmission gear ring is fixedly installed inside the rotating ring. A limit plate is fixedly installed on the outer side of the lower end of the semi-transmission gear ring. A micro control motor is embedded and fixedly installed at the front end of the motor body. A transmission gear is fixedly installed on the front transmission shaft of the micro control motor. A transmission opening is provided through the middle of the upper end of the mounting ring. An extension frame is fixedly installed at the top of the inner end of the semi-transmission gear ring. A filling pipe is fixedly installed through the middle of the lower end of the extension frame. A filling nozzle is fixedly connected to the inner side of the filling pipe. A second filling connection port is fixedly connected to the outer end of the filling pipe. A control panel is fixedly installed on the outer side of the upper end of the motor body.

[0007] Preferably, a liquid level sensor is fixedly installed inside the oil storage tank, the oil storage tank is filled with lubricating oil, and a liquid level observation window is fixedly installed through the front end of the oil storage tank.

[0008] Preferably, the upper end of the oil storage tank is fixedly connected to a filling port, and the upper end of the filling port is threaded with a sealing cap.

[0009] Preferably, the metered fuel pump is composed of a plunger pump, the lower inlet of the metered fuel pump is connected to the fuel outlet, and a pressure sensor is fixedly installed inside the outlet of the metered fuel pump.

[0010] Preferably, a dust cover is fixedly installed on the upper end of the mounting ring, and there are two limiting plates, which are symmetrically distributed on the outer side of the lower end of the semi-transmission gear ring.

[0011] Preferably, the transmission gear is rotatably connected to the upper end of the mounting ring by a bearing seat, and the lower end of the transmission gear passes through the transmission opening and meshes with the upper end of the semi-transmission gear ring.

[0012] Preferably, the inner opening of the filler nozzle faces the upper side of the front bearing of the motor body, and the second filler port is connected to the first filler port through a connecting hose.

[0013] Preferably, the control panel has a built-in control component, which includes a microprocessor, a memory, and a control module.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model controls the activation of a quantitative oil pump through a control component. When the quantitative oil pump is activated, the lubricating oil inside the oil storage tank is pressurized and discharged into the first oil connection port through the oil outlet. The lubricating oil is then delivered to the second oil connection port through the first oil connection port and the connecting hose. When the lubricating oil is delivered to the second oil connection port, it is discharged into the oil pipe through the second oil connection port. When the lubricating oil is discharged into the oil pipe, it is sprayed onto the front bearing of the motor body through the oil nozzle, thereby achieving the function of timed and quantitative oiling of the motor bearing.

[0016] This invention also controls the micro motor to rotate in both directions via a control component. When the micro motor rotates in both directions, it drives the transmission gear to rotate. When the transmission gear rotates, it meshes and drives the semi-transmission gear ring to rotate. When the semi-transmission gear ring rotates, it drives the oiling pipe to rotate via the extension frame. When the oiling pipe rotates, it drives the oiling nozzle to rotate in both directions to adjust the oiling position. This allows for timed and quantitative oiling of the motor bearing while facilitating the adjustment of the oiling nozzle's position in both directions, ensuring that the motor bearing receives sufficient and even oiling lubrication.

A pressure sensor is fixedly installed inside the outlet of the quantitative oiling pump 6 to monitor the pressure status at the outlet of the quantitative oiling pump 6.

[0023] A mounting ring 8 is fixedly installed at the front bearing of the motor body 1, and a dust cover is fixedly installed on the upper end of the mounting ring 8. A rotating ring 9 is rotatably connected to the inner wall of the mounting ring 8 via a rotating shaft. A semi-drive gear ring 10 is fixedly installed on the inner side of the rotating ring 9. Two limit plates 19 are fixedly installed on the outer side of the lower end of the semi-drive gear ring 10, respectively, symmetrically distributed on the outer side of the lower end of the semi-drive gear ring 10, so that the transmission limit is achieved by the limit plates 19 on the outer side of the lower end of the semi-drive gear ring 10. A micro control motor 11 is embedded and fixedly installed at the front end of the motor body 1. A transmission gear 12 is fixedly installed on the transmission shaft of the front end of the micro control motor 11, and the transmission gear 12 is rotatably connected to the upper end of the mounting ring 8 by a bearing seat. A transmission opening 13 is opened through the middle of the upper end of the mounting ring 8, and the lower end of the transmission gear 12 passes through the transmission opening 13 and engages with the upper end of the mounting ring 8. The upper ends of the semi-drive gear rings 10 are meshed with each other. An extension frame 14 is fixedly installed at the top of the inner end of the semi-drive gear rings 10. A refueling pipe 15 is fixedly installed through the middle of the lower end of the extension frame 14. A refueling nozzle 16 is fixedly connected to the inner side of the refueling pipe 15, and the opening of the inner side of the refueling nozzle 16 faces the upper side of the front bearing of the motor body 1. A second refueling connection port 17 is fixedly connected to the outer end of the refueling pipe 15, and the second refueling connection port 17 is connected to the first refueling connection port 7 through a connecting hose. A control panel 18 is fixedly installed on the outer side of the upper end of the motor body 1.

The microprocessor processes the refueling data and instructions, the memory stores the preset refueling parameters and refueling data, and the control module works with the control panel 18 to perform operation control.

[0024] Working principle: In use, this utility model adds lubricating oil into the oil storage tank 2 through the filling port 4. When the lubricating oil is added into the oil storage tank 2, the oil level can be observed through the liquid level observation window 3. After the lubricating oil is added, the timing and quantity parameters of the adding are preset through the control panel 18. After the timing and quantity parameters of the adding are preset, the quantitative filling pump 6 is turned on by the control component. When the quantitative filling pump 6 is turned on, the lubricating oil in the oil storage tank 2 is pressurized and discharged into the first filling connection port 7 through the oil outlet 5, and then transported to the second filling connection port 17 through the first filling connection port 7 and the connecting hose. When the lubricating oil is delivered to the second filling connection port 17, it is discharged into the filling pipe 15 through the second filling connection port 17. When the lubricating oil is discharged into the filling pipe 15, the lubricating oil is sprayed onto the front bearing of the motor body 1 through the filling nozzle 16, thereby realizing the function of timed and quantitative filling of the motor bearing.

[0025] Simultaneously, the micro control motor 11 is activated and rotated in both directions via the control component. When the micro control motor 11 rotates in both directions, it drives the transmission gear 12 to rotate. When the transmission gear 12 rotates, it meshes and drives the semi-transmission gear ring 10 to rotate. When the semi-transmission gear ring 10 rotates, it drives the oiling pipe 15 to rotate via the extension frame 14. When the oiling pipe 15 rotates, it drives the oiling nozzle 16 to rotate in both directions to adjust the oiling position. This allows for timed and quantitative oiling of the motor bearing while facilitating the adjustment of the oiling position of the oiling nozzle 16 in both directions, ensuring that the motor bearing receives sufficient and uniform oiling lubrication.
