Description

Technical Field

[0001] This application relates to the field of speed reducer technology, and more specifically, to an oil change and cleaning system for a pitch speed reducer. Background Technology

[0002] The content in this section provides only background information related to this application and may not constitute prior art.

[0003] A speed reducer is an independent component consisting of gear drives, worm drives, or gear-worm drives enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the driving component and the working machine; its applications are extremely widespread in modern machinery. The lubricating oil in a speed reducer needs to be changed periodically during the long-term operation of the gears and other transmission components.

[0004] In practice, when changing the oil in a gearbox, the old oil is first drained through the drain port, and then new oil is manually added through the inlet to flush out the deposits inside the gearbox. After flushing, new oil is added directly. This method is inconvenient, unscientific, unsafe, inefficient, and the cleaning is not thorough. Existing gearbox oil changes also suffer from inconvenient operation and long change times. Furthermore, because the inside of the gearbox cannot be thoroughly cleaned, even if new lubricating oil is added, it will be secondary contaminated by iron filings and residual oil that has not been drained. Therefore, how to thoroughly clean and change the oil in a gearbox is a technical problem that urgently needs to be solved. Utility Model Content

[0021] This application provides an oil change and cleaning system for a pitch reducer, comprising a reducer 1, a filter element 2, a first three-way valve 3, a second three-way valve 4, a first oil pump 5, a cleaning oil tank 6, a waste oil tank 7, a new oil tank 8, a second oil pump 9, and a valve 10. The reducer 1 includes a first oil filling port 101 and a second oil filling port 102. The first oil filling port 101 is connected to the filter element 2, and the filter element 2 is connected to the cleaning oil tank 6. One end of the first three-way valve 3 is connected to the filter element 2 and the first oil filling port 101, the other end is connected to the cleaning oil tank 6, and the third end is connected to the first oil pump 5. One end of the second three-way valve 4 is connected to the first oil pump 5, the other end is connected to the waste oil tank 7, and the third end is connected to the second oil filling port 102. The new oil tank 8 and the second oil pump 9 are sequentially connected to the second oil filling port 102. The valve 10 is provided at the end of the second oil pump 9.

[0022] The first three-way valve 3 and the second three-way valve 4 regulate the connection of the cleaning system, allowing for flexible switching between oil draining and cleaning, which facilitates the execution of oil change and cleaning functions. When draining oil, open the first oil inlet 101 and the second oil inlet 102, and open the first three-way valve 3 and the second three-way valve 4. This connects the reducer 1, the first three-way valve 3, the oil pump, the second three-way valve 4, and the waste oil tank 7. Start the first oil pump 5 to extract and collect the waste oil in the reducer 1, ensuring thorough cleaning. Then, switch the first three-way valve 3 and the second three-way valve 4, and start the first oil pump 5. This connects the reducer 1, the filter element 2, the cleaning oil tank 6, and the oil pump. The filter element 2 adsorbs impurities, and the cleaning oil enters the reducer 1 for cleaning. After 10 minutes of operation, switch the second three-way valve 4, which connects to the waste oil tank 7, and discharge the cleaning oil into the waste oil collection tank.

[0023] Specifically, a filter device 11 is provided between the new oil tank 8 and the second oil pump 9, wherein the filter device 11 filters the new oil to ensure the quality of the new oil entering the reducer 1.

[0024] Specifically, the cleaning oil drum 6, the waste oil drum 7, and the new oil drum 8 are made of stainless steel.

[0025] Specifically, the first three-way valve 3 and the second three-way valve 4 are electric three-way regulating valves. Electric three-way regulating valves are easy to automate, avoid human interference, and have a higher degree of automation.

[0026] Specifically, the cleaning system also includes a power supply and a controller. The controller is electrically connected to the first three-way valve 3, the second three-way valve 4, the first oil pump 5, the second oil pump 9, and the valve 10. The power supply is electrically connected to the controller, the first three-way valve 3, the second three-way valve 4, the first oil pump 5, the second oil pump 9, and the valve 10. The controller is used to control the switching of the first three-way valve 3 and the second three-way valve 4, and to control the working status of the first oil pump 5 and the second oil pump 9, as well as the opening and closing of the valve 10, thereby improving the overall automation level of the system.

[0027] Specifically, the first three-way valve 3 and the second three-way valve 4 include a motor base, a connecting flange, a valve core, and a three-way pipe connector. The motor base is a flat plate with a fixing hole. The connecting flange has a through hole in its center. The valve core has two circular holes extending to the middle of a cylinder on its side wall, both of which are air inlets. The valve core also includes a force-bearing hole, the shape of which is the same as the shape of the motor's rotating shaft. The three-way pipe connector has a through hole in its center, including an air inlet, a first air outlet, and a second air outlet. The first and second air outlets are on the same pipeline, and the air inlet is perpendicular to the first and second air outlets. The two air inlets of the valve core are connected to the air inlet, the first air outlet, or the second air outlet, respectively. The three-way valve adopts a commonly used three-way valve structure in the prior art to change the connectivity of the system.

[0028] When draining oil, the first oil filling port 101 and the second oil filling port 102 are opened, as are the first three-way valve 3 and the second three-way valve 4. This connects the reducer 1, the first three-way valve 3, the oil pump, the second three-way valve 4, and the waste oil tank 7. The first oil pump 5 is then activated to extract and collect the waste oil from the reducer 1, ensuring thorough cleaning. The first three-way valve 3 and the second three-way valve 4 are then switched, and the first oil pump 5 is activated, connecting the reducer 1, the filter element 2, the cleaning oil tank 6, and the oil pump. The filter element 2 adsorbs impurities, thus cleaning the waste oil. The cleaning oil enters the reducer 1 for cleaning. After working for 10 minutes, switch the second three-way valve 4, which is connected to the waste oil tank 7, and discharge the cleaning oil into the waste oil collection tank. When adding new oil, open valve 10, open the first oil filling port 101 and the second oil filling port 102, and start the second oil pump 9. Add oil by controlling the flow rate at valve 10. When full, close valve 10 and the second oil pump 9, and close the first oil filling port 101 and the second oil filling port 102.

[0029] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art, all of which fall within the protection scope of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
