Description

Technical Field

[0001] This utility model belongs to the field of power transmission technology, and relates to a gearbox, particularly an oil-filled gearbox. Background Technology

[0002] Oil-filled gearboxes are a very common and important mechanical transmission device. Their core feature is the use of lubricating oil to lubricate gears and bearings in order to reduce friction, reduce wear, dissipate heat, cool down, prevent rust, and clean.

[0003] Traditional oil-filled gearboxes use an oil pump to circulate and spray oil. However, gears wear down during operation, causing the oil to become contaminated with grease, impurities, and metal shavings. When oil containing impurities participates in lubrication, it causes foreign objects to stick to the gears, thus accelerating gear damage. Usually, a filter screen is installed to intercept impurities. However, after working for a long time, the mesh of the filter screen becomes clogged, leading to oil circuit blockage, oil pump dry running, and gear wear. Therefore, it is necessary to develop a filter. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing an oil filling gearbox with automatic shut-off function for filtering blockages.

[0005] The objective of this utility model can be achieved through the following technical solution: an oil-filled gearbox, characterized in that it includes a gearbox housing, an oil pump, and oil pipes. An oil reservoir is provided on the side wall of the gearbox housing. The oil reservoir is provided with several guide pipes that connect to the interior of the gearbox housing. Two symmetrical guide strips are provided on the inner wall of the oil reservoir. A filter box is provided on one side of the guide strips. A filter screen is provided on one side of the filter box. A sealed cavity is provided at the bottom of the filter box. A flow-guiding step is provided on the filter box. A magnet is provided on the flow-guiding step. The end of the flow-guiding pipe is placed at the top of the filter box. The oil pump is located on the side wall of the gearbox housing. The oil pipes are fixed to both ends of the oil pump. The bottom of the oil pipe is placed inside the oil reservoir.

[0006] In the aforementioned oil injection gearbox, the oil pump is equipped with a control switch, the filter box is equipped with a control lever, and the control lever abuts against the control switch.

[0007] In the aforementioned oil-filled gearbox, the bottom of the oil pump is provided with a fitting plate, and the gearbox housing is provided with a limiting plate for limiting the fitting plate.

[0008] In the aforementioned oil-filled gearbox, the gearbox housing includes an upper housing, a lower housing, and a side housing.

[0009] In the aforementioned oil-filled gearbox, the top of the oil reservoir is provided with a cover, and the cover is provided with several locking bolts, the bottom of which is fixed to a guide strip.

[0010] Compared with existing technologies, this oil filling gearbox has a floating filter box in the oil reservoir to filter impurities in batches and categories, extending the time before the filter screen becomes clogged. A control rod on the floating filter box touches the oil pump switch to achieve mechanical control connection. Due to the negative effect of filter screen clogging, the filter box settles, thereby controlling the oil pump to shut down and preventing unfiltered oil from participating in lubrication. Even without the control rod contacting the oil pump, it can still prompt the user that the filter box is clogged and allow for radial cleaning of the filter screen. Attached Figure Description

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figures 1-5As shown, this oil-filled gearbox includes a gearbox housing 7, an oil pump 4, and oil pipes 3. An oil reservoir 6 is located on the side wall of the gearbox housing 7. The oil reservoir 6 has several guide pipes 13 connecting to the interior of the gearbox housing 7. Two symmetrical guide strips 12 are located on the inner wall of the oil reservoir 6. A filter box 14 is located on one side of each guide strip 12, and a filter screen 15 is located on one side of each filter box 14. A sealed cavity 19 is located at the bottom of the filter box 14, and a flow-guiding step 18 is provided on the filter box 14. A magnet 16 is located on the flow-guiding step 18. The ends of the guide pipes 13 are placed within the filter box 14. At the top, the oil pump 4 is installed on the side wall of the gearbox housing 7, and the oil pipe 3 is fixed to both ends of the oil pump 4. At the bottom, the bottom of the oil pipe 3 is placed inside the oil reservoir 6. The lubricating oil enters the filter box 14 from the guide pipe 13. The oil flows through the magnet 16 and attracts metal debris in the oil. Then, it passes through the filter screen 15 to intercept flexible impurities and sludge. The filter box 14 floats above the oil due to the sealed cavity 19 at the bottom and is limited to one end of the oil reservoir 6 by the guide bar 12. After the filter screen 15 is blocked, the oil accumulates in the filter box 14 and the filter box 14 sinks into the oil.

[0019] Preferably, the oil pump 4 is equipped with a control switch 5, and the filter box 14 is equipped with a control lever 17. The control lever 17 is in contact with the control switch 5. When the filter screen 15 on the filter box 14 is unobstructed, the filter box 14 is in a floating state, and the top control lever is always in contact with the control switch 5. When the filter screen 15 is blocked, the filter box 14 sinks, the control switch 5 is released, and the oil pump 4 is turned off.

[0020] Preferably, the oil pump 4 has a fitting plate 9 at its bottom, and the gearbox housing 7 has a limiting plate 20 that limits the fitting plate 9. The oil pump 4 is installed and fixed by inserting the limiting plate 20 into the fitting plate 9, which facilitates disassembly and maintenance.

[0021] Preferably, the gearbox housing 7 includes an upper housing 1, a lower housing 8, and a side housing 2. The gearbox housing 7, composed of multiple housings, facilitates the maintenance of designated components.

[0022] Preferably, the top of the oil tank 6 is provided with a cover 11, and the cover 11 is provided with a number of locking bolts 10, the bottom of which is fixed to the guide strip 12.

[0023] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0024] Although this document frequently uses terms such as upper housing 1, side housing 2, oil pipe 3, oil pump 4, control switch 5, oil reservoir 6, gearbox housing 7, lower housing 8, fitting plate 9, locking bolt 10, cover 11, guide strip 12, flow guide pipe 13, filter box 14, filter screen 15, magnet 16, control lever 17, flow guide step 18, sealed cavity 19, and limiting plate 20, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
