It is commonly used as a reduction transmission device between the prime mover and the working machine. It matches the speed and transmits torque between the prime mover and the working machine or actuator, and is widely used in modern machinery.

[0003] For example, the application number is CN202221933211.7, which is a reducer that is easy to oil. The above utility model patent stores the lubricating oil through an oil storage tank. However, since the inner bottom surface of the oil tank in the above utility model is placed horizontally and the lubricating oil itself has a certain viscosity, when the lubricating oil in the oil storage tank gradually becomes less, it will cause the circulation speed of the lubricating oil located on the inner bottom surface parallel to the oil outlet to slow down without the action of external force, resulting in reduced work efficiency.

[0004] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0023] See also Figure 1 、 Figure 2 and Figure 4Preferably, the oil scraping assembly of the present invention includes a driving motor 7 provided on one side of the outside of the oil tank 5, a bidirectional screw 8 provided at the output end of the driving motor 7, and two sets of scrapers 9 sleeved on the bidirectional screw 8 and abutting against the inner bottom surface of the oil tank 5. The bidirectional screw 8 is driven to rotate by the driving motor 7, thereby driving the scraper 9 to move.

[0024] See also Figure 2 In addition, the bidirectional screw 8 of the present invention passes through the interior of the oil tank 5 and is rotatably connected to the oil tank 5. The two groups of scrapers 9 are respectively sleeved on the opposite threaded portions of the bidirectional screw 8. The bidirectional screw 8 drives the scrapers 9 to move toward each other, thereby pushing the lubricating oil on the bottom surface of the oil tank 5 and improving the circulation speed of the lubricating oil when it is gradually reduced.

[0025] See also Figure 2 and Figure 3 Furthermore, the interior of the oil tank 5 of the utility model is penetrated by a fixed column 10 which is parallel to the bidirectional screw 8 on the horizontal plane. The fixed column 10 passes through the two groups of scrapers 9. The fixed column 10 improves the stability of the movement of the scraper 9 driven by the bidirectional screw 8.

[0026] See also Figure 1 and Figure 2 Moreover, the top of the oil tank 5 of the utility model is penetrated by a one-way screw 13 which is screwed to the oil tank 5. The top of the one-way screw 13 is provided with a handle 12, and the bottom of the one-way screw 13 is provided with a pressure plate 14. The one-way screw 13 is rotated by the handle 12 to move the pressure plate 14 downward, thereby achieving the abutment between the pressure plate 14 and the oil outlet 5.1.

[0027] See also Figure 3 Better yet, the radius of the pressure plate 14 of the present invention is greater than the radius of the oil outlet 5.1. The oil outlet 5.1 can be closed by the pressure plate 14 compacting and blocking the oil outlet 5.1.

[0028] See also Figure 1 、 Figure 2 and Figure 4 Finally, the fuel tank 5 of the present invention is connected to the support base 4 by a plurality of groups of L-shaped connecting plates 15. The L-shaped connecting plates 15 facilitate the connection and fixation of the fuel tank 5 and the support base 4, thereby improving the stability of the fuel tank 5.

[0029] The working principle of this utility model:

[0030] like Figure 1-Figure 4As shown, when lubricating the reducer body 1, the lubricating oil must first be injected into the oil tank 5 for storage, so as to facilitate the subsequent multiple lubrication of the reducer body 1, and then the oil outlet hose 11 is connected to the reducer body 1, and then the handle 12 is turned to move the one-way screw 13 and the pressure plate 14 upward, so that the oil outlet 5.1 is opened, and the lubricating oil flows into the reducer body 1. When the lubricating oil added to the reducer body 1 is sufficient, the handle 12 can be rotated in the opposite direction to move the one-way screw 13 and the pressure plate 14 downward, so that the pressure plate 14 closes the oil outlet 5.1. When the amount of lubricating oil in the oil tank 5 gradually decreases, the circulation speed of the lubricating oil slows down, and the drive motor 7 can be turned on. The drive motor 7 drives the bidirectional screw 8 to rotate, and the rotation of the bidirectional screw 8 drives the two sets of scrapers 9 to move toward each other. The two sets of scrapers 9 drive the lubricating oil located on the bottom surface of the oil tank 5 to move, and produce a gathering effect, so that the circulation speed of the lubricating oil at the oil outlet 5.1 is increased, so that the lubricating oil located in the oil tank 5 can be oiled to the inside of the reducer body 1 more quickly, thereby improving work efficiency. At the same time, the back and forth movement of the scraper 9 can also play a role in activating the lubricating oil located in the oil tank 5, preventing the lubricating oil from being degraded due to standing still. After the work is completed, the drive motor 7 can be rotated in the opposite direction to drive the scraper 9 to reset, which is convenient for subsequent use.

[0031] In summary, the utility model provides an oiling device for a reducer, comprising: a base, a reducer body is provided on the base, four groups of support columns are symmetrically provided on the base, the tops of the four groups of support columns are provided with support seats, an oil tank is provided above the support seat, an oil inlet is provided on the top of the oil tank, an oil outlet is provided at the bottom of the oil tank, an oil outlet hose is provided at the oil outlet, the oil outlet hose is connected to the reducer body, a through hole is provided at the connection between the support seat and the oil outlet hose, and an oil scraper assembly is provided inside the oil tank. To sum up, the utility model realizes the movement of the lubricating oil on the inner bottom surface of the oil tank through the oil scraper assembly, so that the lubricating oil can be pushed into the oil outlet, thereby improving the circulation speed of the lubricating oil when it is gradually decreasing. At the same time, the back and forth movement of the scraper can also play a role in mobilizing the lubricating oil in the oil tank, preventing the lubricating oil from being degraded due to standing still. Moreover, the pressure plate is driven downward by the one-way screw to close the oil outlet. When the reducer body is not oiled, the oil outlet of the oil tank is closed.
