Description

Technical Field

[0001] The present invention relates to the technical field of reduction motors, and in particular to a reduction motor with automatic lubrication function and a use method thereof. Background Art

[0002] A reduction motor is an integration of a reducer and an electric motor (motor). This integration is also commonly called a gear motor or gear motor.

[0003] Lubricating oil is one of the most common lubrication methods for reducers. It has good lubrication properties, can effectively reduce the friction and wear of mechanical equipment, and improve transmission efficiency. The selection of lubricating oil needs to consider factors such as the temperature, load and speed of the working environment. Generally, mechanical equipment needs to choose lubricating oil with higher viscosity under high speed and high load. The addition and replacement of lubricating oil is also very important. Regularly checking the cleanliness and performance of lubricating oil is essential to ensure the normal operation of mechanical equipment.

[0004] The use of lubricants also brings a problem, that is, the increase in cost. In addition to the cost of the lubricant itself, sealing measures must be considered to ensure that the lubricant is not contaminated by dust and impurities, which undoubtedly adds additional costs. In life and work, we can observe that some reducers do not use lubricants, but rely on dry friction between teeth to operate. For example, the first-stage reduction gear in the fast-feeding wire cutting machine is made of nylon, which uses its self-lubricating properties and lighter working load to achieve oil-free lubrication. Similarly, reducers on children's toys often do not use any lubrication method, because such products themselves have low cost, low price, and usually have no maintenance period, so there is no need to increase the cost of lubricants. However, in the industrial field, even some small reducers, such as reducers for electric doors and windows or sweeping robots, are lubricated with grease. This lubrication method is economical and practical, which can ensure that the gears are fully lubricated without worrying about oil leakage or oil stains. For high-precision reducers used in industrial robots, grease can further improve product performance. In scenarios with strict noise requirements, special noise reduction grease will also be selected. As for the engine gearbox on the car, splash lubrication is usually used for lubrication.

[0005] Lubrication is crucial for gearboxes. It not only transfers the heat generated during gear transmission to the box body for dissipation through lubricating oil, but also affects the thermal power of the reducer. Both oil seals and lubricating oil need to be able to withstand high temperatures, because heat is one of the key factors affecting the size of the reducer. The type and volume of lubricating oil, the size of the reducer, the gear speed, etc. will affect the thermal power of the reducer. In higher-end application scenarios, such as the reducer of a helicopter, forced lubrication is used to automatically inject lubricating oil into the reducer through an externally installed forced lubrication system. As an industrial mother machine, machine tools usually use splash lubrication, pressure oil injection lubrication or circulating oil injection lubrication. After opening the reducer cover of an old machine tool, the internal engine oil, the oil injection hole and the oil injection copper tube can be clearly seen. In addition to regular oil changes, refueling can also be performed through the oil injection hole. In the heavy industry, low-speed and heavy-load mining reducers and reducers for metallurgy and steel often use splash lubrication. In order to improve the lubrication performance of the reducer, some industrial reducers will also improve their lubrication conditions by adding oil tanks or increasing the oil level.

[0006] For example, the application number 202310153342.6 discloses a vertical reducer with automatic lubrication function. The technical problem to be solved is: in the prior art, the top bearing is difficult to lubricate, and during lubrication, the amount of lubricating oil is not easy to control, which is prone to waste and even oil leakage. The technical solution of the present invention is: a vertical reducer with automatic lubrication function, including a vertical reducer and a connecting shell, etc.; a connecting shell is installed on the right side of the vertical reducer. The present invention realizes that when the temperature of the input shaft reaches a certain value, the mercury between the heat conduction plate and the skateboard expands and contracts as the temperature of the input shaft continues to rise. When the switch is continuously squeezed by the push block, the battery pack keeps the two coils energized. When the coils are energized, electromagnetic force is generated synchronously during the rotation of the input shaft, and the lubricating oil inside the oil storage tank is pressed into the connection port through the oil inlet pipe, thereby lubricating and cooling the input shaft.

[0007] However, most of the current automatic lubrication reduction motors have problems such as large consumption of lubricating oil per unit time, large power consumption caused by continuous lubrication, short service life of lubricating equipment, complex lubrication structure, high cost, inconvenient maintenance, large amount of lubricating cooling oil generated in the gearbox for large amount of heat dissipation, poor heat dissipation effect of the worm, and high energy consumption of the equipment.

By setting up a mist lubrication cooling mechanism, the consumption of lubricating oil per unit time is reduced, the power consumption generated by continuous lubrication is reduced, and the service life of the lubrication equipment is increased. In addition, by spraying the oil mist evenly on the turbine disc, the uniformity of lubrication is improved, the wear resistance of the turbine disc is improved, and the service life of the gearbox of the reduction motor is increased. Oil mist lubrication provides fresh and cooled lubricating oil for the gearbox, takes away the heat generated by friction, reduces the temperature of the meshing worm gear, and thus extends the service life of the turbine worm. After using the oil mist lubrication system, the operator does not need to use an oil pot to add lubricating oil to each motor. It only needs to maintain the main engine, saving labor costs.

[0010] 2. By setting a pressurized liquid separator block, a liquid spray storage sleeve, and a cyclone mist nozzle, the lubricating oil is reduced in flow and pressurized in the pressurized liquid separator block, and then a local high-pressure storage bag is formed in the liquid spray storage sleeve. The liquid forms a centripetal vortex motion along the groove wall through the centripetal rotary liquid inlet groove of the cyclone mist nozzle, and forms a high-pressure mist at the outlet of the central liquid spray hole. Through the design of the above combined mechanism, conventional lubricating oil is formed into oil mist through a simple mechanical mechanism, the structure is simple and ingenious, and the manufacturing cost is reduced; 3. By setting a one-way lubrication valve in the quantitative bearing lubrication mechanism, the bearing can be lubricated regularly and quantitatively, which reduces bearing noise, significantly reduces friction and wear, thereby reducing energy loss and improving the operating efficiency and performance of the machine. Regular and quantitative lubrication can effectively protect the bearing and prevent the accumulation of metal chips and oil stains, thereby extending the service life of the equipment. Through automatic oilers and other equipment, oil can be added regularly and quantitatively, reducing manual intervention, reducing maintenance costs, and reducing the need for unexpected downtime and maintenance; 4. The graphite lubrication mechanism can be set to automatically lubricate the bearing according to the heating condition of the bearing. When the temperature is low, the lubricating oil cannot pass through the graphite sheet. When the bearing temperature rises, the lubricating oil becomes thinner due to heat, and the bearing is lubricated through the graphite sheet. While lubricating the bearing, it protects the internal environment of the bearing and cools the bearing at the same time; 5. By setting up the worm center cooling mechanism, the worm is the most difficult to dissipate heat during the rotation and heating process. While maintaining the sufficient rigidity of the worm, the worm center cooling mechanism is added to reduce the large amount of lubricating cooling oil generated in the gear box for large-scale heat dissipation. The worm is evenly cooled inside through the worm center cooling hole, which reduces the energy consumption of the equipment and improves the heat dissipation effect of the worm. 6. By setting up a cooling water distribution plate, the cooling oil for cooling the worm not only cools the inside of the worm, but also lubricates the worm bearing at the same time. The structure is ingenious and practical and functional. BRIEF DESCRIPTION OF THE DRAWINGS
