Description

Technical Field

[0001] The utility model relates to the technical field of crawler track lubrication, in particular to a lubricating crawler track assembly. Background Art

[0002] The track is a flexible chain link driven by the driving wheel and encircling the driving wheel, road wheels, idler wheels, and support rollers. The track consists of track shoes and track pins. The track pins connect the track shoes to form the track chain. The track shoes have holes at both ends that mesh with the driving wheel, and an induction tooth in the middle to align the track and prevent it from falling off when the tank turns or rolls. The side in contact with the ground has reinforced anti-skid ribs (also known as treads) to increase the track shoe's strength and adhesion to the ground.

[0003] At present, some existing crawlers have a meshing connection between their driving wheels and the crawler tracks and are in dry contact. Therefore, when the driving wheel drives the crawler tracks to rotate, the tooth blocks of the driving wheel will directly rub against the holes on the surface of the crawler tracks in dry contact, which will cause the tooth blocks of the driving wheel to wear out after long-term use and cause damage to the tooth blocks. The service life of the tooth blocks is relatively short, which relatively increases the cost of use. Therefore, we propose a lubricated crawler assembly to solve or improve the above problems.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The gear train 2 is connected to the gear train 2 by the support 1, and the gear train 2 is connected to the gear train 2 by the support 1. The oil pump 11 of described outer ring 7 is connected with the oil pump 12 of described outer ring 7, and the oil pump 11 of described outer ring 7 is connected with the oil pump 12 of described outer ring 7.

[0019] The interior of the adjustment component includes a first through hole 9 opened on the surface of the oil storage bin 8, the interior space of the first through hole 9 is connected to the interior space of the oil storage bin 8, and two groups of first through holes 9 are symmetrically opened on the surface of the oil storage bin 8. The oil storage bin 8 is located on one side of the hollow oil guide plate 7, and an adjustment plate 10 is inserted into the support 1 and is located on the side of the oil storage bin 8. A third through hole 14 is opened on the surface of the adjustment plate 10, and the third through hole 14 is located on one side of the first through hole 9. The number of the third through holes 14 is the same as the number of the first through holes 9. The interior space of the third through hole 14 is connected to the first through hole 9 and the interior space of the hollow oil guide plate 7, and an adjustment screw 11 is inserted into the support 1 and passes through the adjustment plate 10. The adjustment screw 11 is threaded with the adjustment plate 10 Connection, when the adjusting screw 11 rotates, it will drive the threaded adjustment plate 10 to move, and when the adjusting plate 10 moves, it will drive the third through hole 14 opened on the surface to move, and when the third through hole 14 moves, it will change the overlapping area between the first through hole 9 and the third through hole 14, thereby changing the amount of lubricating oil that can flow between the third through hole 14 and the first through hole 9 under the same pressure, thereby adjusting the amount of lubricating oil flowing through the first through hole 9 and the third through hole 14 to the inside of the hollow oil guide plate 7. One end of the adjusting screw 11 passes through the surface of the support 1 and an adjusting handwheel 6 is fixed to the top. By rotating the adjusting handwheel 6, the fixed adjusting screw 11 can be driven to rotate, and the other end of the adjusting screw 11 is rotatably mounted inside the support 1 through a bearing.

[0020] The working principle is that when the driving wheel 2 rotates, the fixed gear block rotates, when the gear block rotates through one side of the hollow oil guide plate 7, the lubricating oil in the oil storage bin 8 flows into the inside of the first through hole 9 through gravity, and flows into the inside of the hollow oil guide plate 7 through the first through hole 9 and the third through hole 14, so that the lubricating oil flows out from one side of the second through hole 13 through the inside of the hollow oil guide plate 7, thereby smearing the lubricating oil on the surface of the driving wheel 2 gear block through the second through hole 13, and when the gear block passes through the wear-resistant contact piece 12, the lubricating oil on the surface of the gear block is evenly smeared on the surface of the gear block through the wear-resistant contact piece 12, and the excess lubricating oil is scraped off to remain on the surface of the second through hole 13, which facilitates smearing on the surface of the next group of gear blocks when the next group of gear blocks passes through, thereby improving the utilization rate of the lubricating oil. When the gear block passes through the surface of the second through hole 13, the lubrication of the surface of the driving wheel 2 gear block is completed, so that the gear block on the surface of the driving wheel 2 is lubricated through the lubricating oil when the gear block is engaged with the track 4, thereby avoiding the problem that the gear block of the driving wheel 2 is damaged due to large wear after long-time use caused by dry friction. The service life of the gear block is relatively long, and the use cost is relatively reduced. At the same time, when it is necessary to adjust the lubrication requirement according to the use environment, the adjusting hand wheel 6 is rotated to drive the adjusting screw 11 to rotate, and the adjusting plate 10 is driven to move when the adjusting screw 11 rotates, so that the adjusting plate 10 drives the third through hole 14 to move, thereby changing the overlapping area between the first through hole 9 and the third through hole 14, thereby changing the amount of lubricating oil that can flow between the third through hole 14 and the first through hole 9 under the same pressure, thereby adjusting the amount of lubricating oil flowing out according to the lubrication requirement, improving the adaptability of the lubricating track assembly to different lubrication requirements, and facilitating use.
