Description

Technical Field

[0001] The present application relates to the technical field of gear oil replacement devices, and in particular to a gear oil replacement device. Background Art

[0002] Gear oil mainly refers to the lubricating oil of the transmission and rear axle. It is different from engine oil in terms of usage conditions, composition and performance. Gear oil mainly lubricates gears and bearings, prevents wear and corrosion, and helps gears dissipate heat. When replacing gear oil, a gear oil replacement device is required.

[0003] However, the gear oil replacement device needs to pay attention to the selection of lubricating oil. Different lubricating oils are prohibited from being mixed. Most existing gear oil replacement devices do not have a cleaning function. After an oil change, the lubricating oil is viscous and will remain on the inner wall of the oil tank of the oil replacement device, which will cause the remaining lubricating oil to mix with the different types of lubricating oil injected during the next oil change. Mixing different lubricating oils will affect the operation of the gears and further affect the working efficiency of the machine. Therefore, those skilled in the art provide a gear oil replacement device to solve the problems raised in the above background technology. Utility Model Content

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The oil tank 1 is provided with a slide groove 8, and the scrapers 5 are all movably embedded in the slide groove 8. The scrapers 5 are all movably embedded in the slide groove 8 so that the movable plate 3 moves downward when the motor 9 is started.

[0024] Reference Figure 1 , Figure 2 and Figure 3 The transmission assembly includes a motor 9 and a threaded rod 10. The motor 9 is fixedly mounted on the top of the fuel tank cover 2, and the threaded rod 10 is fixedly connected to the output shaft of the motor 9. The threaded rod 10 is threadedly connected to the movable plate 3. By starting the motor 9 to drive the threaded rod 10, power can be provided for the movable plate 3 to move downward.

[0025] Reference Figure 1 and Figure 4 A wide groove 11 is provided on the movable disk 3, in which a rotating electromagnet 13 is fixedly installed. The setting of the rotating electromagnet 13 can drive the arc plate 7 to rotate slightly, so that the gap between the arc plate 7 and the inner wall of the movable disk 3 can be cleaned.

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The elastic member includes a second spring 14 and a telescopic rod 15, which are fixedly connected to the arc plate 7 and the rotating electromagnet 13.
