Description

Wear-resistant thrust wheel Technical Field The utility model relates to the technical field of thrust wheels, in particular to a wear-resistant thrust wheel. Background During the operation of the crawler-type engineering machine, the thrust wheel is used as a core bearing component and is in direct and continuous contact with the crawler track sections. The contact relation not only enables the thrust wheel to bear huge weight of the engineering machinery, but also generates high-frequency relative friction with the caterpillar links under the driving of the caterpillar tracks, and the generated pressure and friction force form continuous loss on the tread of the thrust wheel. More serious, in typical operation scenes such as mines, construction sites and the like, the thrust wheels also need to bear continuous scouring and grinding of hard particles such as soil, sand and the like, wherein the particles continuously squeeze and slide in contact gaps between the crawler belt and the thrust wheels, and the peeling of wheel surface materials is accelerated like abrasive materials, so that the abrasion degree is further increased. The existing thrust wheel exposes an obvious short plate when the working condition is met. On the one hand, the rapid wear of the tread has become a common phenomenon. The common thrust wheel mostly adopts medium carbon alloy steel such as 50Mn, 40Mn2 and the like as wheel body materials, even though the wheel surface hardness can only reach 45-52HRC through quenching and tempering and surface quenching, under the heavy load working condition, the contact stress of the wheel surface and a chain track section can reach 800-1000MPa, so that abrasion marks such as grooves, pits and the like appear on the wheel surface in a short time, and the average service life is often less than 2000 hours. On the other hand, the rim is used as an edge supporting structure of the thrust wheel, and is subjected to lateral force in the track guiding process, so that deformation and even fracture are easily generated due to material fatigue, and particularly when the track is operated on rough terrain, the deformation rate of the rim is higher than that of a flat road surface by more than 30%, and the normal running track of the track is directly influenced.
