[0030] Specifically, a plurality of second mounting holes 3 are formed on the outer surfaces of both ends of the sprocket body 1 , and the second mounting holes 3 are the same size as the first mounting holes 203 .

[0031] Furthermore, the first mounting hole 203 is aligned with the second mounting hole 3 , and the fastening bolts 204 are fixed in the inner cavities of the first mounting hole 203 and the second mounting hole 3 , so as to achieve quick installation and disassembly of the anti-wear mechanism 2 .

[0032] Specifically, a front end cover 4 is fixedly installed on the left side of the drag chain wheel body 1 , and a floating oil seal 5 is fixedly installed on the right side of the front end cover 4 .

[0033] Furthermore, the floating oil seal 5 is mainly used for sealing to prevent the leakage of lubricating oil or hydraulic oil. It allows the tugboat shaft 7 to move freely within a certain range while maintaining a good sealing effect.

[0034] Specifically, a through hole 6 is opened on the left side of the front end cover 4, and the inner cavity of the through hole 6 penetrates through the inner cavity of the drag chain wheel body 1, and a drag wheel shaft 7 is fixedly installed thereon.

[0035] Furthermore, the tug shaft 7 is provided to support and fix the sprocket wheel, thereby ensuring that the sprocket wheel can rotate smoothly, thereby guiding and supporting the crawler track on the excavator.

[0036] Specifically, a pressing plate 8 is fixedly installed on the right end of the tugboat shaft 7 , and the pressing plate 8 is fixedly connected to the tugboat shaft 7 via a third bolt 9 .

[0037] Furthermore, the pressure plate 8 is provided to fix and support the tugboat shaft 7, thereby ensuring the stability and smoothness of the sprocket wheel during use.

[0038] Specifically, a plurality of first fixing holes 10 are formed around the left side of the front end cover 4 , and first bolts 11 are fixedly installed in the inner cavities of the first fixing holes 10 .

[0039] Furthermore, the front end cover 4 is provided to seal and protect the internal structure of the sprocket wheel body 1 and protect it from external influences and prevent debris and dust from entering the interior.
