Description

Technical Field

[0001] This utility model relates to the field of differential technology, specifically to a differential housing for engineering machinery. Background Technology

[0002] The differential housing of construction machinery is a key component of the differential, playing a vital role in its normal operation and performance. The main function of the differential housing is to house the differential gear assembly, transmit power to the vehicle's drive wheels, and enable the vehicle to achieve different speeds of the left and right drive wheels under different driving conditions such as turning, thus ensuring stable vehicle operation. The housing is often made of materials such as ductile iron and steel. Ductile iron has good strength, toughness, and wear resistance, and can withstand the impact and vibration from vehicle loads and complex road surfaces.

[0003] Existing differential housings for construction machinery are widely used. When using these devices, they usually require the use of lubricating oil. However, during use, gear wear produces iron filings, which existing devices cannot absorb. Excessive iron filings may cause abnormal noises or even jamming of the differential. Furthermore, existing housings are all sealed, resulting in poor heat dissipation. Therefore, a new differential housing for construction machinery is proposed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a differential housing for engineering machinery to solve the problems mentioned in the background art, such as the inability of existing devices to adsorb iron filings inside the device and poor heat dissipation performance.

A third threaded groove is formed on the inner side of the oil drain pipe. A tee pipe, communicating with the oil drain pipe, is rotatably connected to the bottom end of the oil drain pipe. Connecting pipes, symmetrically arranged and communicating with the tee pipe, are fixedly connected to both ends of the tee pipe. An oil pump, communicating with the connecting pipe, is fixedly connected to the end of the connecting pipe furthest from the tee pipe.

[0008] Preferably, a hexagonal ring is fixedly connected to the outer side of both the oil drain pipe and the bidirectional threaded pipe. The oil pump is fixedly connected to the top of the differential housing and communicates with the inner side of the differential housing. The bottom of the bidirectional threaded pipe is spirally connected to the inner side of the third threaded groove. The two ends of the connecting block are fixedly connected to the inner side of the outer ring and the outer side of the inner ring, respectively.

[0009] Preferably, the inner ring has a second threaded groove at its top end, a threaded block is spirally connected to the inner side of the second threaded groove, and a vertically arranged magnetic column is fixedly connected to the top end of the threaded block. There are multiple second threaded grooves, and the second threaded grooves are distributed along the polar axis at the top end of the inner ring.

[0010] Preferably, a heat sink is fixedly connected to the outside of the connecting pipe, and there are multiple heat sinks that are evenly distributed on the outside of the connecting pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, through the oil outlet pipe, the first threaded groove, the filter assembly, the bidirectional threaded pipe, the outer ring, the filter ring, the connecting block, the inner ring, the filter plate, the oil drain pipe, the third threaded groove, the hexagonal ring, the tee pipe, the connecting pipe and the oil pump, when the device is in use, the oil pump is started, and the lubricating oil mixed with iron filings enters the bidirectional threaded pipe and passes through the filter plate and the filter ring. The filter plate and the filter ring intercept the iron filings above the outer ring. Finally, the filtered lubricating oil enters the inside of the differential housing. The filter assembly can clean and collect the iron filings inside the differential housing, preventing excessive iron filings from affecting the normal operation of the differential.

[0013] 2. In this utility model, through the provided second threaded groove, threaded block and magnetic column, during the oil pump circulation lubricating oil process, the magnetic column can adsorb some iron filings on the outside of the magnetic column, preventing excessive iron filings from accumulating on the filter ring and the top of the filter plate and causing blockage.

[0014] 3. In this utility model, through the connection pipe, oil pump and heat sink, during the circulation of lubricating oil by the oil pump, the heat of the oil inside the connection pipe is transferred to multiple heat sinks. The heat is dissipated into the air through the heat sinks. The cooled lubricating oil enters the inside of the differential housing, thereby reducing the heat of the differential housing. The setting of multiple heat sinks can effectively reduce the heat of the differential housing and prevent the differential from overheating. Attached Figure Description

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] A differential housing for engineering machinery includes a differential housing 1. A vertically arranged oil outlet pipe 2, communicating with the inner side of the differential housing 1, is fixedly connected to the bottom end of the differential housing 1. A first threaded groove 3 is formed on the inner side of the oil outlet pipe 2. A filter assembly 4 is provided inside the first threaded groove 3. An oil drain pipe 5 is provided outside the filter assembly 4. A third threaded groove 6 is formed on the inner side of the oil drain pipe 5. A three-way pipe 8, communicating with the oil drain pipe 5, is rotatably connected to the bottom end of the oil drain pipe 5. Connecting pipes 9, symmetrically arranged and communicating with the three-way pipe 8, are fixedly connected to both ends of the three-way pipe 8. An oil pump 10, communicating with the connecting pipe 9, is fixedly connected to the end of the connecting pipe 9 away from the three-way pipe 8. The filter assembly 4 includes a bidirectional threaded pipe 41 spirally connected to the inner side of the first threaded groove 3. An outer ring 42 is provided inside the bidirectional threaded pipe 41. A filter ring 43 is fixedly connected to the inner side of the outer ring 42. Multiple symmetrically arranged... The connecting block 44 is configured such that an inner ring 45 is fixedly connected to the inner side of the filter ring 43, and a filter plate 46 is fixedly connected to the inner side of the inner ring 45. Hexagonal rings 7 are fixedly connected to the outer sides of the oil drain pipe 5 and the bidirectional threaded pipe 41. The oil pump 10 is fixedly connected to the top of the differential housing 1 and communicates with the inner side of the differential housing 1. The bottom of the bidirectional threaded pipe 41 is spirally connected to the inner side of the third threaded groove 6. The two ends of the connecting block 44 are fixedly connected to the inner side of the outer ring 42 and the outer side of the inner ring 45, respectively. When the device is in use, the oil pump 10 is started, and the lubricating oil mixed with iron filings enters the bidirectional threaded pipe 41 and passes through the filter plate 46 and the filter ring 43. The filter plate 46 and the filter ring 43 intercept the iron filings above the outer ring 42. Finally, the filtered lubricating oil enters the inner side of the differential housing 1. The filter assembly 4 can clean and collect the iron filings on the inner side of the differential housing 1, preventing excessive iron filings from affecting the normal operation of the differential.

[0026] The inner ring 45 has a second threaded groove 47 at its top end. A threaded block 48 is spirally connected to the inner side of the second threaded groove 47. A vertically arranged magnetic column 49 is fixedly connected to the top end of the threaded block 48. There are multiple second threaded grooves 47, which are distributed along the polar axis at the top end of the inner ring 45. During the circulation of lubricating oil by the oil pump 10, the magnetic column 49 can adsorb some iron filings on the outside of the magnetic column 49, preventing excessive iron filings from accumulating on the top of the filter ring 43 and the filter plate 46 and causing blockage.

[0027] A heat sink 11 is fixedly connected to the outside of the connecting pipe 9. There are multiple heat sinks 11, which are evenly distributed on the outside of the connecting pipe 9. During the circulation of lubricating oil by the oil pump 10, the heat of the oil inside the connecting pipe 9 is transferred to the multiple heat sinks 11. The heat is dissipated into the air through the heat sinks 11. The cooled lubricating oil enters the inside of the differential housing 1, thereby reducing the heat of the differential housing 1. The arrangement of multiple heat sinks 11 can effectively reduce the heat of the differential housing 1 and prevent the differential from overheating.

[0028] Workflow: Before using the device, install the differential housing 1 and the differential on the construction machinery. Power on the device and connect an external control device. Then, screw the threaded block 48 at the bottom of the magnetic column 49 into the inner side of the second threaded groove 47 at the top of the inner ring 45. Place the outer ring 42 and its connecting components inside the bidirectional threaded tube 41. Screw the bidirectional threaded tube 41 into the inner side of the first threaded groove 3 in the oil outlet pipe 2. Screw the oil drain pipe 5 inside the hexagonal ring 7 into the bottom of the bidirectional threaded tube 41, so that the bidirectional threaded tube 41... The bottom is spirally connected to the third threaded groove 6. During the use of the device, gear wear will generate iron filings. When the oil pump 10 is started, the oil pump 10 draws out the lubricating oil mixed with iron filings from inside the differential housing 1. The lubricating oil enters the inner side of the bidirectional threaded pipe 41 through the oil outlet pipe 2. At this time, the lubricating oil passes through the filter plate 46 and the filter ring 43 on one side of the connecting block 44. The filter plate 46 and the filter ring 43 intercept the iron filings above the outer ring 42. The magnetic column 49 adsorbs some of the iron filings on the outside of the magnetic column 49, preventing excessive iron filings from accumulating on the top of the filter ring 43 and the filter plate 46 and causing blockage. The lubricating oil passes through the filter ring 43 and the filter plate 46 and enters the inner side of the oil drain pipe 5 and the three-way pipe 8, and enters the oil pump 10 and the inner side of the differential housing 1 through the connecting pipe 9. During this process, the heat of the oil inside the connecting pipe 9 is transferred to multiple heat sinks 11. The heat is dissipated into the air through the heat sinks 11. The cooled lubricating oil enters the inner side of the differential housing 1, thereby reducing the heat of the differential housing 1. The arrangement of multiple heat sinks 11 can effectively reduce the heat of the differential housing 1. To effectively reduce the heat of the differential housing 1 and prevent the differential from overheating, after using the device for a period of time, the bidirectional threaded tube 41 on the inner side of the hexagonal ring 7 can be unscrewed from the inside of the oil outlet pipe 2 and the oil drain pipe 5. The outer ring 42 and its connecting components can be removed, and the magnetic column 49 can be unscrewed from the top of the inner ring 45, thereby cleaning the surface of the filter ring 43, the filter plate 46 and the magnetic column 49. The filter assembly 4 can clean and collect iron filings on the inside of the differential housing 1, preventing excessive iron filings from affecting the normal operation of the differential.
