Description

Technical Field

[0001] This utility model belongs to the field of engineering support roller technology, specifically relating to an engineering support roller with a high sealing structure. Background Technology

[0002] Track rollers are an important component of the "four wheels and one track" (i.e., drive wheels, track rollers, carrier rollers, idler wheels, and tracks) of tracked construction machinery chassis. Track rollers are used to support the weight of construction machinery (such as excavators, bulldozers, tractors, etc.), roll on the track rails (track links) or track pads, and also restrain the tracks to prevent lateral slippage.

[0003] Track rollers, as a key component of tracked construction machinery, are ingeniously designed with the dynamic interaction and durability of the axle in mind. To ensure smooth and efficient rotation around the axle, a precise dimensional difference is designed at both ends. This dimensional difference not only optimizes rotation and reduces frictional resistance but also improves overall operational stability. However, this carefully designed clearance can also become a potential source of problems in real-world working environments.

[0004] Due to the complexity of the engineering work environment, foreign objects such as dust, gravel, and mud are easily stirred up and splashed around during track movement. When the track roller rotates at high speed, these foreign objects may take advantage of the tiny gaps created by the difference in size between the two ends to penetrate into the internal space of the track roller. Once intruded, these foreign objects may rub against internal mechanical parts, leading to accelerated wear and even serious malfunctions such as jamming or breakage. More seriously, some foreign objects may contain corrosive substances, which, over time, can erode the material of the track roller, causing irreversible damage. Utility Model Content

[0005] The purpose of this invention is to provide an engineering support roller with a high-sealing structure, aiming to solve the problem that due to the complexity of engineering working environments, foreign objects such as dust, gravel, and mud are easily stirred up and splashed around during track movement. When the support roller rotates at high speed, these foreign objects may take advantage of the tiny gaps created by the difference in size between the two ends to penetrate into the internal space of the support roller. Once intruded, these foreign objects may rub against internal mechanical parts, leading to accelerated wear and even serious malfunctions such as jamming or breakage. More seriously, some foreign objects may contain corrosive substances, which, under long-term exposure, will erode the material of the support roller, causing irreversible damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an engineering support roller with a high sealing structure, comprising a wheel body, an axle installed inside the wheel body, an mounting head installed at each end of the axle, and a sealing shaft installed at the mating end of the axle and the mounting head;

[0007] An inner ring is welded to the inside of each end of the wheel body. A sealing sleeve is welded to one side of the inner ring. The inner wall of the other end of the sealing sleeve is welded to the outer wall of the outer ring of the sealing shaft. The inner ring of the sealing shaft is fixedly sleeved on the outer wall of the center rod. The outer walls of both sides of the sealing shaft are respectively sealed and connected to a sealing gasket.

[0008] To facilitate the installation of the sealing shaft between the axle and the mounting head, in a preferred embodiment of this high-sealing engineering support roller, the axle has a first pair of interfaces on its outer wall facing the sealing shaft, and a first threaded groove at the center end of the outer wall facing the sealing shaft. The mounting head has a second pair of interfaces on its outer wall facing the sealing shaft, and a second threaded groove at the center end of the outer wall facing the sealing shaft. A first pair of connectors is fixedly installed on one side of the central rod, and a second pair of connectors is fixedly installed on the other side of the central rod. The first pair of connectors and the second threaded groove are threaded together, and the second pair of connectors and the first threaded groove are threaded together.

[0009] In order to maintain a good sealing structure at the connection between the sealing shaft and the wheel axle and the mounting head, as a preferred engineering support roller with a high sealing structure according to this utility model, the two sealing gaskets are respectively connected to the first pair of interfaces and the second pair of interfaces, and the sealing shaft forms a sealing structure at the connection between the two sealing gaskets and the wheel axle and the mounting head.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] By pre-fitting an inner ring into the outer wall of both ends of the wheel body, then welding one end of the sealing sleeve to the outer wall of the inner ring, and then installing the sealing shaft on the wheel axle and the mounting head, and then welding the inner wall of the other end of the sealing sleeve to the outer wall of the sealing shaft, the two ends of the wheel body can be wrapped inside the sealing sleeve, thereby maintaining a good sealing mechanism at both ends of the wheel body to prevent foreign objects from entering the wheel body from the side opening area and causing damage during use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6 The present invention provides the following technical solution: an engineering support roller with a high sealing structure, including a wheel body 1, an axle 2 installed inside the wheel body 1, an mounting head 3 installed at each end of the axle 2, and a sealing shaft 6 installed at the mating end of the axle 2 and the mounting head 3;

[0022] An inner ring 4 is welded to the inside of each end of the wheel body 1. A sealing sleeve 5 is welded to one side of the inner ring 4. The inner wall of the other end of the sealing sleeve 5 is welded to the outer wall of the outer ring of the sealing shaft 6. The inner ring of the sealing shaft 6 is fixedly sleeved on the outer wall of the center rod 7. The outer walls on both sides of the sealing shaft 6 are respectively sealed and connected to a sealing gasket 8.

[0023] The lateral and vertical length of the sealing sleeve 5 is the same as the maximum lateral and vertical length between the inner ring 4 and the sealing shaft 6. The maximum outer diameter of the sealing sleeve 5 is the same as the maximum diameter of the inner ring 4. The minimum diameter of the sealing sleeve 5 is slightly larger than the maximum diameter of the sealing shaft 6. This allows the sealing sleeve 5 to be docked and welded to the inner ring 4 and the sealing shaft 6.

[0024] Preferably, the outer wall of the wheel axle 2 facing the sealing shaft 6 has a first pair of interfaces 202, and the center end of the outer wall of the wheel axle 2 facing the sealing shaft 6 has a first threaded groove 201. The outer wall of the mounting head 3 facing the sealing shaft 6 has a second pair of interfaces 302, and the center end of the outer wall of the mounting head 3 facing the sealing shaft 6 has a second threaded groove 301. A first pair of connectors 701 and a second pair of connectors 702 are fixedly installed on one side of the center rod 7. The first pair of connectors 701 and the second threaded groove 301 are threaded together, and the second pair of connectors 702 and the first threaded groove 201 are threaded together. Two sealing gaskets 8 are respectively connected to the first pair of interfaces 202 and the second pair of interfaces 302. The sealing shaft 6 forms a sealing structure with the wheel axle 2 and the mounting head 3 through the two sealing gaskets 8.

[0025] In practical use, first put the sealing sleeve 5 on one side of the wheel axle 2, then put the sealing shaft 6 on the outer wall of the center rod 7 and fix it by welding.

[0026] Next, the two sealing gaskets 8 are respectively connected to the first pair of interfaces 202 and the second pair of interfaces 302. After the connection is completed, the first pair of connectors 701 and the second pair of connectors 702 are connected to the corresponding second pair of interfaces 302 and the first pair of interfaces 202 by thread and tightened. In this way, the sealing shaft 6 can squeeze the sealing gaskets 8 into the corresponding first pair of interfaces 202 and the second pair of interfaces 302.

[0027] Next, the large end of the sealing sleeve 5 is welded to the outer wall of the inner ring 4, and the inner wall of the small end of the sealing sleeve 5 is welded to the outer wall of the outer ring of the sealing shaft 6. In this way, the connection between the end of the wheel body 1 and the wheel axle 2 can be wrapped inside the sealing sleeve 5. Thus, in actual use, this structure can form a good high-sealing structure to prevent foreign objects from entering the interior of the wheel body 1 and causing damage.

[0028] The outer ring of the sealing shaft 6 has a movable contact structure with the wheel axle 2 and the mounting head 3.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
