Description

Technical Field

[0001] This utility model relates to the field of gear lubrication technology, and in particular to a high-speed gear lubricating oil directional injection device. Background Technology

[0002] With the rapid development of high-end equipment manufacturing, aerospace, wind power generation, and new energy vehicles, gear transmission systems, as core power transmission components, are evolving towards high speed, heavy load, lightweight, and high power density. High-speed gearboxes are a typical example, often reaching speeds of tens of thousands of revolutions per minute. Under these extreme conditions, the meshing efficiency, operating temperature, vibration and noise, and fatigue life of the gears directly determine the reliability, energy consumption, and maintenance costs of the entire equipment. Therefore, it is necessary to design a high-speed gear lubricating oil directional injection device.

[0003] To address this, patent CN216368255U discloses an automatic lubricating oil spraying device for ball mill gear transmission, comprising a mounting base, a pinion, a large gear, and a spraying mechanism. A gear mounting shaft is provided between the mounting bases, and the pinion is mounted on the gear mounting shaft, meshing with the large gear. A gear ring cover is provided on the mounting base, and the spraying mechanism is mounted on the gear ring cover. The spraying mechanism consists of several welded brackets, a spray gun, an oil distribution connector, several oil guide pipes, and several nozzles. Several welded brackets are provided on the gear ring cover. This utility model has a simple structure and reasonable design, enabling automatic spraying of lubricating oil onto the gears, eliminating the need for manual lubrication. This prevents gear wear caused by workers failing to spray lubricating oil in a timely manner or forgetting to do so, reducing the workload of workers. Simultaneously, the lubricating oil is sprayed onto the large gear, ensuring effective lubrication, reducing lubricating oil loss, and improving lubrication efficiency.

[0004] Although the gear-driven automatic lubricating oil injection device mentioned above can ensure effective lubricating oil injection during use, it is inconvenient to know the oil level in the oil tank after long-term use. Therefore, it is necessary to design a high-speed gear lubricating oil directional injection device. Utility Model Content

[0005] The purpose of this invention is to provide a high-speed gear lubricating oil directional injection device to solve the problem that it is inconvenient to know the oil level in the oil tank after long-term use of existing gear lubricating oil directional injection devices.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-speed gear lubricating oil directional injection device, including a large gear;

[0007] A small gear is meshed with one side of the large gear, an oil tank is provided on one side of the large gear, and a pumping structure is provided on one side inside the oil tank.

[0008] A liquid level detection structure is provided on the other side of the inside of the oil tank. The liquid level detection structure includes a mounting plate fixed to one side of the top of the oil tank. A meter head is fixed to the top of the mounting plate, and a dial is fixed to one side of the meter head. The liquid level detection structure also includes a probe located on one side of the inside of the oil tank.

[0009] The oil tank has a spray structure fixed on the side near the large gear.

[0010] Furthermore, the spraying structure includes a spray gun, a diverter pipe, a nozzle, and a delivery pipe. The delivery pipe is fixed to one side of the bottom of the oil tank. The top end of the delivery pipe extends to the outside of the oil tank and is fixedly mounted with a spray gun. The bottom end of the spray gun, near the pinion, is fixed with a diverter pipe, and the bottom end of the diverter pipe is fixed with a nozzle.

[0011] Furthermore, the nozzle is located above the meshing point of the large gear and the small gear.

[0012] Furthermore, the pumping structure includes an air inlet pipe, a pneumatic barrel pump, an air outlet pipe, and a piston. The pneumatic barrel pump is fixedly installed on one side of the top of the oil tank. An air inlet pipe is fixed on one side of the top of the pneumatic barrel pump, and an air outlet pipe is fixed on one side of the bottom of the pneumatic barrel pump. The piston is located inside the oil tank.

[0013] Furthermore, an air compressor is externally connected to the top of the intake pipe.

[0014] Furthermore, an electronic unit is installed inside the meter head.

[0015] Furthermore, the top of the probe extends to the outside of the oil tank and is fixedly connected to the bottom of the mounting plate.

[0016] The advantages of the high-speed gear lubricating oil directional injection device provided by this utility model are as follows:

[0017] By incorporating a liquid level detection structure, the probe can detect changes in the liquid level inside the lubricating oil. The probe can monitor the liquid level height of the lubricating oil inside the oil tank, and the liquid level height can be read directly on-site via the dial. This eliminates the need for other complex equipment, making the process convenient and quick. This device enables easy detection of the lubricating oil level inside the oil tank, improving the ease of use of the high-speed gear lubricating oil directional injection device.

[0018] By incorporating a spray structure with the nozzle fixed above the meshing point of the large and small gears, the lubricating oil can be directly and accurately sprayed onto the critical meshing area of ​​the gears. By delivering the lubricating oil directly to the meshing point that requires the most lubrication and heat dissipation, an oil film can be formed instantly, reducing friction and wear, and quickly carrying away the large amount of heat generated by meshing. This effectively prevents gear seizure and pitting, thus enabling the device to perform directional lubrication and improving the convenience and efficiency of the high-speed gear lubricating oil directional spraying device during use.

[0019] By incorporating a pumping structure, the pneumatic energy from the air compressor can be converted into hydraulic energy through the air inlet pipe, providing stable and continuous pressure and flow to the entire lubrication system. This ensures that the lubricating oil can overcome pipeline resistance and be delivered to the nozzle, enabling the device to easily increase the stable pressure of the lubricating oil and improving the working efficiency of the high-speed gear lubricating oil directional injection device during use.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 The present invention provides a high-speed gear lubricating oil directional injection device, which includes a large gear 1.

[0028] Reference Figures 1-5 A small gear 2 is meshed with one side of a large gear 1. An oil tank 4 is provided on one side of the large gear 1. A pumping structure 5 is provided on one side inside the oil tank 4. The pumping structure 5 includes an air inlet pipe 51, a pneumatic barrel pump 52, an air outlet pipe 53, and a piston 54. The pneumatic barrel pump 52 is fixedly installed on one side of the top of the oil tank 4. An air inlet pipe 51 is fixed on one side of the top of the pneumatic barrel pump 52. An air outlet pipe 53 is fixed on one side of the bottom of the pneumatic barrel pump 52. The piston 54 is located inside the oil tank 4. An air compressor is connected to the top of the air inlet pipe 51.

[0029] With an external power supply, compressed air enters the upper air chamber of the pneumatic pump 52 through the air inlet pipe 51. The compressed air pushes the piston 54, converting the air pressure energy into the reciprocating mechanical motion of the piston 54. The piston 54 squeezes the lubricating oil, causing the lubricating oil to be transported outward through the delivery pipe 34.

[0030] Reference Figures 1-5 On the other side of the interior of the oil tank 4, a liquid level detection structure 6 is provided. The liquid level detection structure 6 includes a mounting plate 63 fixed to one side of the top of the oil tank 4. A meter 61 is fixed to the top of the mounting plate 63, and a dial 62 is fixed to one side of the meter 61. The liquid level detection structure 6 also includes a probe 64 located on one side of the interior of the oil tank 4. An electronic unit is installed inside the meter 61, and the top of the probe 64 extends to the outside of the oil tank 4 and is fixedly connected to the bottom of the mounting plate 63.

[0031] When the lubricating oil level changes, the length of the probe 64 covered by the liquid changes, and the average dielectric constant of the medium between the probe 64 and the inner wall of the oil tank 4 changes, which will cause a linear change in the total capacitance. The electronic unit inside the meter 61 detects this tiny capacitance change and converts the capacitance change into a standard digital signal, thereby accurately indicating the current liquid level height, making it easy to observe the liquid level inside the lubricating oil.

[0032] Reference Figures 1-5 A spray structure 3 is fixed on the side of the oil tank 4 near the large gear 1. The spray structure 3 includes a spray gun 31, a diverter pipe 32, a nozzle 33, and a delivery pipe 34. The delivery pipe 34 is fixed on one side of the bottom of the oil tank 4. The top end of the delivery pipe 34 extends to the outside of the oil tank 4 and is fixedly installed with the spray gun 31. The bottom end of the spray gun 31 near the small gear 2 is fixed with the diverter pipe 32. The bottom end of the diverter pipe 32 is fixed with the nozzle 33. The nozzle 33 is located above the meshing point of the large gear 1 and the small gear 2.

[0033] The pumping structure 5 generates pressure to pump the lubricating oil out of the oil tank 4 and deliver it to the spray gun 31 through the delivery pipe 34. After entering the spray gun 31, the lubricating oil flows into the distribution pipe 32, which distributes the oil flow to the nozzle 33. Finally, the lubricating oil is sprayed out through the nozzle 33. The nozzle 33 can form the oil into a concentrated oil jet or atomized oil mist, covering the gear tooth surface in the most suitable form.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
