Description

Technical Field

[0001] The utility model relates to the technical field of track rollers, and more particularly to a wear-resistant track roller. Background Art

[0002] Wear-resistant track rollers bear a certain amount of pressure and weight, primarily providing support and stability. In crawler-type construction machinery, such as excavators and bulldozers, track rollers support the weight of the entire machine and, through the tracks, keep the machine stable on the ground, preventing track slippage. Wear-resistant track rollers also effectively restrain the tracks, preventing them from slipping laterally. When construction machinery is operating on complex terrain or sloped ground, track rollers ensure the tracks stay close to the ground, preventing the machine from tipping over or losing control.

[0003] In existing public documents, patent announcement number CN107776696A discloses a wear-resistant double-sided track roller, which forms a wear-resistant sheet assembly ring groove in the straight bottom wall to accommodate the wear-resistant sheet. This invention realizes the assembly of the floating seal rubber ring through the arc-shaped bottom wall of the floating seal ring assembly hole, and the wear-resistant sheet is fixed separately through the wear-resistant sheet assembly ring groove in the straight bottom wall. At the same time, the fixing holes can position and assist in fixing the wear-resistant sheet. The layout of the fixing holes can ensure that it does not affect the mechanical properties of the wheel body. The present invention can effectively increase the service life of the track roller. However, this track roller has the following problems;

[0004] When the track roller is in use, although the external rubber can play a wear-resistant role, during the wear process, due to the presence of impurities on the ground, the impurities will be lifted up and squeezed on the rubber. If they are not cleaned in time, the impurities will continue to squeeze and contact the rubber part, making it more difficult to push. This will cause the rubber part to continue to slide and rub against the chain instead of rolling friction. The friction is large and it is very easy to damage the track roller. For this reason, a wear-resistant track roller is needed. Utility Model Content

The arc-shaped scraper supports the scraping bar, and the scraping bar can scrape and clean the impurities on the wear-resistant rubber layer. When the wear-resistant rubber layer rotates counterclockwise, the impurities on the wear-resistant rubber layer can rotate onto the scraping bar, and the scraping bar scrapes and cleans the impurities on the outer wall of the wear-resistant rubber layer, avoiding continuous extrusion of impurities on the wear-resistant rubber layer to cause continuous damage, thereby avoiding sliding friction between the wear-resistant rubber layer and the ground.

At the same time, when the auxiliary shaft is rotating, the lubricating oil can be poured in from the mouth of the oil inlet hole, and then the connection between the track roller and the mounting sleeve is lubricated. Finally, the lubricating oil is poured into the arc-shaped oil hole position for lubrication.

When the wear-resistant rubber layer rotates counterclockwise, impurities on the wear-resistant rubber layer can be rotated onto the scraping bars, preventing impurities from being continuously squeezed on the wear-resistant rubber layer and causing continuous damage. At the same time, it can ensure that the wear-resistant rubber layer rolls smoothly, avoiding sliding friction between the wear-resistant rubber layer and the ground. In this way, the wear-resistant rubber layer is not easily damaged and has better wear resistance and durability.

[0020] As attached Figure 1-5 A wear-resistant supporting roller is shown, and a wear-resistant cleaning mechanism is provided on the wear-resistant supporting roller. The setting of the wear-resistant cleaning mechanism can ensure that the wear-resistant rubber layer 4 rolls smoothly, avoiding sliding friction between the wear-resistant rubber layer 4 and the chain. In this way, the wear-resistant rubber layer 4 is not easily damaged and has better wear resistance and durability. The specific structural setting of the wear-resistant cleaning mechanism is as follows.

[0021] In this technical solution, as shown in the attached Figure 1-3As shown, the load-bearing shaft 2 is fixedly connected to the inner wall of the housing block 1, and the supporting roller 3 is rotatably connected to the outer wall of the load-bearing shaft 2. The outer wall of the supporting roller 3 is provided with a wear-resistant cleaning mechanism. The wear-resistant cleaning mechanism includes a wear-resistant rubber layer 4 fixedly connected to the outer wall of the supporting roller 3, and a curved scraper 5 is slidably connected to the outer wall of the wear-resistant rubber layer 4. A scraper bar 6 is fixedly connected to one side of the curved scraper 5, and the scraper bar 6 is slidably connected to the wear-resistant rubber layer 4. A support bar 7 is fixedly connected to the top of the outer wall of the curved scraper 5, and the support bar 7 is fixedly connected to the housing block 1.

The support bar 7 supports the arc scraper 5, and the arc scraper 5 supports the scraping bar 6, and the scraping bar 6 can scrape and clean the impurities on the wear-resistant rubber layer 4.
