[0002] In modern mechanical equipment, lubrication is an important link to ensure the normal operation of mechanical equipment and extend its service life. Especially in the gear transmission system, due to its complex working conditions and heavy load, reasonable lubrication is particularly important. However, the existing oiling devices mostly use manual or automatic oil spraying, but these methods often have problems such as uneven oiling, difficulty in controlling the amount of oil, grease overflow during installation, and high labor costs in actual applications, which leads to increased gear wear and reduced work efficiency. In severe cases, it may even cause equipment failure. At the same time, with the development of mechanical equipment towards high efficiency and high speed, higher requirements are placed on the performance of the oiling device. It is necessary to have the characteristics of quantitative, timing, and intelligence to ensure that the right amount of lubricating oil can be provided under different working conditions, thereby ensuring the good operation of the gear.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] A quantitative gear oiling device is mainly composed of an oil circuit system, a hydraulic reset system, an oiling system and a main support frame. The oil circuit system includes an oil tank 1, an oil pump 2, a regulating valve 3, a mesh nozzle 4, a stopper 5, a rubber ring 6, an oil inlet pipe 7 and an oil return pipe 8; the hydraulic reset system includes an upper hydraulic cylinder 9, a lower hydraulic cylinder 10, an upper hydraulic rod 11 and a lower hydraulic rod 12; the oiling system includes a pump body 13, an oil distribution plate 14, a sealing gasket 15 and a pump cover 16; the main support frame includes a buffer table 17, a column 18 and an upper crossbeam 19.

[0026] The limiter 5 is located inside the oil distribution plate 14, and the rubber ring 6 is embedded around the limiter 5; the lower hydraulic rod 12 and the lower hydraulic pump are located in the pump body 13; the upper hydraulic rod 11 is connected to the pressure head, and the lower hydraulic rod 12 is connected to the limiter 5; the oil distribution plate 14 is fixed in the pump body 13 through a dovetail groove; a sealing gasket 15 is padded between the pump body 13 and the pump cover 16, the pump body 13 and the pump cover 16 are connected by bolts, and the pump body 13 and the buffer table 17 are connected by bolts; the buffer table 17, the column 18, and the upper beam 19 are welded together.

[0027] The oil inlet pipe 7 is connected to a regulating valve 3, through which the input of the oil flow is controlled.

[0028] The hydraulic reset system is combined with the oiling system. When the gear moves down to the oil distribution plate 14, the microcontroller automatically controls the start and stop of the oil pump 2 according to a preset program to ensure that the oil output is uniform and stable each time.

[0029] A mesh nozzle 4 is installed at the oil inlet pipe 7 so that the oil can evenly fill the oil distribution plate 14.

[0030] The oil distribution plate 14 is used in conjunction with the gears, and the oil distribution plates 14 of different sizes can be replaced to quantitatively oil the gears of different models.

[0031] The lubricating oil that is not absorbed by the gears or is in excess can be returned to the oil tank 1 through the oil return pipe 8 and reused.

[0032] The upper hydraulic rod 11 is connected with a pressure head, and the lower hydraulic rod 12 is connected with a limiter 5. The upper hydraulic rod 11 and the lower hydraulic rod 12 are linked to each other. When the upper hydraulic rod 11 is extended, the lower hydraulic rod 12 is retracted; when the upper hydraulic rod 11 is retracted, the lower hydraulic rod 12 is extended.

[0033] The oil tank 1 is fixed on the column 18, and the pump body 13 is fixed to the buffer table 17 by bolts.

[0034] A sealing gasket 15 is provided between the pump body 13 and the pump cover 16 , and the pump body 13 and the pump cover 16 are connected by bolts.

[0035] Compared with the prior art, the beneficial effects of the present invention are: a gear quantitative oiling device can achieve accurate quantitative oiling of gears, improve oiling efficiency, reduce oil consumption, and extend the service life of gears.

[0036] The gear 100 is placed above the stopper 5. The hydraulic reset system can be controlled manually or automatically. When the hydraulic reset system is started, the upper hydraulic rod 11 extends and the pressure head slowly moves downward. When it contacts the gear 100 and / or the stopper 5, the lower hydraulic cylinder 10 works, and the lower hydraulic rod 12 drives the stopper 5 to move downward, and the gear is moved into the oil distribution plate 14. When the gear reaches the injection position where the outer periphery of the gear is radially opposite to the outlet of the oil inlet channel and the inlet of the oil return channel on the oil distribution plate 14, for example, a sensor is set in the pump body 13 to detect that the gear or the stopper 5 moves to the injection position, and the oil pump 2 in the oil circuit system is started. The oil pump 2 delivers oil to the oiling system. The oil passes through a set regulating valve 3 such as a throttle valve and enters the oil inlet pipe 7 and the oil inlet channel. The throttle valve works intermittently. The oil inlet amount can be changed by changing the size of the throttle valve port and the working time. According to the size of the gear, the oil amount and the operating state can be monitored through the control panel, and the throttle valve switch can be adjusted to control the oil inlet amount, so as to make full use of the oil amount. After the oil enters the oil inlet pipe 7, it enters the oil distribution plate 14 through the mesh nozzle 4. The gap between the inner wall of the oil distribution plate 14 and the outer periphery of the gear is fixed to form a fixed space, which provides conditions for the oil to be evenly applied around the gear, thereby improving the working efficiency of gear oiling. When the throttle valve stops working and the oil no longer enters through the oil inlet pipe 7, the lower hydraulic cylinder 10 works, the lower hydraulic rod extends, and the lower hydraulic rod 12 drives the limiter 5 and the gear to move upward. At the same time, the upper hydraulic rod 11 contracts, and the upper hydraulic rod 11 drives the pressure head to move upward. The gear is pushed out of the pump body 13 by the limiter 5, and the lubricating oil that is not absorbed by the gear or excess can be returned to the oil tank 1 through the return oil pipeline, thereby reducing waste. In addition, the oil distribution plate 14 is installed in the pump body 13 through a dovetail groove, and the oil distribution plate 14 can be disassembled and replaced, so that the quantitative oiling device can easily replace the corresponding oil distribution plate 14 according to gears of different sizes, ensuring that the grease is evenly distributed on the gear surface, thereby expanding the scope of application of the quantitative oiling device. In this way, the gear quantitative oiling device can provide lubrication for mechanical equipment efficiently and accurately, extend the service life of the equipment, improve lubrication efficiency and extend the service life of the gears.

[0037] The device aims to solve the problems of the traditional gear oiling method, such as the inability to accurately control the amount of oil, poor lubrication effect, and oil waste, so as to improve the oiling and lubrication effect of the gear, reduce friction, and extend its service life. This technology is widely used in automated production lines, industrial machinery, automotive transmission systems and other fields, and can effectively ensure the smooth operation and performance reliability of the equipment.

[0038] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, method, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
