[0002] The gearbox bears the force from the wind wheel and the reaction force generated by the gear transmission. It must have sufficient rigidity to withstand the force and torque, prevent deformation, and ensure the transmission quality. The design of the gearbox housing should be carried out in accordance with the layout arrangement of the wind turbine power transmission, processing and assembly conditions, and easy inspection and maintenance. With the rapid development of the gearbox industry, more and more industries and different companies have used gearboxes, and more and more companies have grown and developed in the gearbox industry. Gear oil is an important lubricant made of petroleum lubricant base oil or synthetic lubricant, with extreme pressure anti-wear agent and oiliness agent added. Gear oil is widely used in industry and is used in various gear transmission devices to prevent tooth surface wear, abrasion, sintering, etc., to extend its service life and improve the power transmission efficiency. However, during the oil filling process, foam is very easy to generate. First, we need to see whether the oil level in the gear box is appropriate. There may be a false oil level phenomenon.

Air and moisture will cause increased foam and contaminate the gear oil, making it impossible to use it normally. Not only will it waste raw materials, but it will also easily cause damage to the structure inside the gear box. Utility Model Content

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-2 The utility model provides a technical solution: an automatic oil filling device for a gear box, comprising an oil storage tank 1, lifting frames 2 are fixedly installed on both sides of the oil storage tank 1, a base 3 is fixedly installed at the bottom end of the lifting frame 2, a conduit 4 is fixedly penetrated through the bottom surface of the oil storage tank 1, a solenoid valve is installed on the conduit 4, a pressurizing structure is installed on the oil storage tank 1, one end of an oil inlet pipe 7 is fixedly connected to the side of the oil storage tank 1, the oil inlet pipe 7 is inclined, a feed hopper 11 is fixedly installed on the oil inlet pipe 7, the feed hopper 11 is fixedly installed with the oil storage tank 1, the other end of the oil inlet pipe 7 is buckled with a top cover 8, and a side of the top cover 8 close to the oil inlet pipe 7 is fixedly installed with a pull rope 9.

[0016] During the process of oiling the gearbox, the oil storage tank 1 is placed on a conveying mechanism, such as a conveyor belt, etc. The lifting frame 2 uses electric lifting to adjust the height of the oil storage tank 1 and is used in conjunction with the conveying structure. The conveying structure and the lifting frame 2 are widely used and are all prior art. No further elaboration is made here. After the lubricating oil and defoaming agent are mixed, they are poured into the oil inlet pipe 7 through the feed hopper 11. One end of the oil inlet pipe 7 is blocked by the top cover 8. The lubricating oil enters the oil storage tank 1 along the oil inlet pipe 7 and flows into the oil storage tank 1 along the pull rope 9. Under the action of the pull rope 9, the lubricating oil flows along the pull rope 9, which can achieve a drainage effect. The lubricating oil slowly enters the oil storage tank 1, which can reduce the generation of bubbles. After the lubricating oil is prepared, a pressurized structure is used, and the lubricating oil is left to stand for a period of time to discharge the internal bubbles. When filling the oil, the oil filling hole on the gear box is opened. The conduit 4 is located at the oil filling hole on the gear box. The solenoid valve is used to control the conduit 4, and the discharge of the lubricating oil in the conduit 4 is remotely controlled. The lubricating oil is automatically injected into the gear box to complete the oil filling operation.

[0017] Specifically, a rubber ball 10 is fixedly mounted on the other end of the pull rope 9 .

[0018] A rubber ball 10 is fixed at the other end of the pull rope 9. After pouring lubricating oil into the oil storage tank 1, the top cover 8 is removed. The top cover 8 drives the pull rope 9 to move from the inside of the oil inlet pipe 7, pulling the rubber ball 10. The rubber ball 10 can undergo elastic deformation and be snapped into the oil inlet pipe 7 to seal the oil inlet pipe 7 to prevent debris from entering the oil inlet pipe 7. The rubber ball 10 can increase the weight of the bottom end of the pull rope 9 to prevent the pull rope 9 from shaking.

[0019] Specifically, the pressurizing structure includes an electric push rod 12, which is fixedly assembled on the surface of the oil storage tank 1. The bottom end of the electric push rod 12 movably penetrates the oil storage tank 1. The bottom end of the electric push rod 12 is fixedly assembled with a push plate 13. The bottom surface of the push plate 13 is sleeved with a rubber pad 14. The rubber pad 14 fits tightly with the inner wall of the oil storage tank 1. An exhaust pipe 15 is fixedly penetrated on the push plate 13. The bottom end of the exhaust pipe 15 penetrates the exhaust pipe 15. The top end of the exhaust pipe 15 penetrates the oil storage tank 1. The top end of the exhaust pipe 15 is fixedly assembled with an air valve 16.

[0020] The pressurizing structure can increase the pressure in the oil storage tank 1, so that the bubbles mixed in the lubricating oil can be quickly eliminated. After the pull rope 9 is pulled out, the electric push rod 12 is started, and the electric push rod 12 begins to extend, pushing the push plate 13 and the rubber pad 14 on the push plate 13 to move together. When the push plate 13 and the rubber pad 14 move to the bottom of the oil inlet pipe 7, the space in the oil storage tank 1 continues to decrease. As the space continues to decrease, the purpose of pressurization is achieved. The pressure acts on the lubricating oil, which can accelerate the release speed of the bubbles. After the pressure increases to a certain level and the bubbles are released, the air valve 16 is opened to exhaust from the exhaust pipe 15 to avoid a large amount of lubricating oil being discharged at the moment the solenoid valve is opened after the pressure increases.

[0021] Specifically, the exhaust pipe 15 is made of transparent glass.

[0022] The exhaust pipe 15 is made of transparent glass, so that the lubricating oil can be seen entering the exhaust pipe 15 directly, the amount of air in the oil storage tank 1 can be judged, and the air valve 16 can be opened to perform exhaust operation in time.

[0023] Specifically, the bottom end of the conduit 4 is fixedly connected with a hose 6 .

[0024] A section of hose 6 is installed at the bottom end of the conduit 4, and the hose 6 can extend into the oil filling hole of the gear box to prevent the lubricating oil from dripping to the outside of the gear box during the oil filling process.

[0025] Specifically, an annular groove is formed on the bottom surface of the oil storage tank 1 , and an electric heating plate 17 is fixedly mounted on the inner wall of the annular groove.

[0026] In order to further avoid the generation of excessive bubbles in the lubricating oil, an annular groove is provided under the oil storage tank 1, and an annular electric heating plate 17 is installed. The oil storage tank 1 is heated by the electric heating plate 17 to keep the oil storage tank 1 in a warm state at all times, thereby avoiding the phenomenon that low temperature will increase the viscosity of the lubricating oil and reduce the speed of bubble release.

[0027] Working principle: During the process of oiling the gearbox, the oil storage tank 1 is placed on a conveying mechanism, such as a conveyor belt, etc. The lifting frame 2 uses electric lifting to adjust the height of the oil storage tank 1 and is used in conjunction with the conveying structure. After the lubricating oil and defoaming agent are mixed, they are poured into the oil inlet pipe 7 through the feed hopper 11. One end of the oil inlet pipe 7 is blocked by the top cover 8. The lubricating oil enters the oil storage tank 1 along the oil inlet pipe 7 and flows into the oil storage tank 1 along the pull rope 9. Under the action of the pull rope 9, the lubricating oil flows along the pull rope 9, which can achieve a drainage effect. The lubricating oil slowly enters the oil storage tank 1, which can reduce the generation of bubbles. After the lubricating oil is prepared, a pressurizing structure is used, and the lubricating oil is left to stand for a period of time to discharge the internal bubbles. When oiling, the oil filling hole on the gearbox is opened. The conduit 4 is located at the oil filling hole on the gearbox. The conduit 4 is controlled by an electromagnetic valve to remotely control the discharge of the lubricating oil in the conduit 4, and the lubricating oil is automatically injected into the gearbox to complete the oiling operation.
