Crawler-type traveling system: in the field of engineering machinery, a crawler type traveling system is widely adopted next to a tire type traveling system. Common track-type construction machines are: tractors, bulldozers, loaders, pipe hoists, rakers, excavators, rotary drills, and the like.
Supporting a chain wheel: the crawler belt is used for dragging the upper part of the crawler belt, preventing the crawler belt from excessively drooping so as to reduce the vibration and jumping phenomenon during the movement of the crawler belt and prevent the crawler belt from sliding off laterally. The number of carrier sprockets is typically two on each side.
The crawler-type engineering machinery has a severe working environment and is generally large-scale capital construction engineering, open-pit metal mines or coal mines and the like. The track is in direct contact with the ground and is often subject to wear and erosion by silt, stones and ore. Particularly due to the shock and localized loading caused by uneven transmission and uneven ground, making its track one of the most vulnerable parts of the entire bulldozer. Compared with other components, the chain supporting wheel has high position, small stress and good working condition, but as one of main components of the crawler-type traveling system, the abrasion is also the first failure of the chain supporting wheel, and the replacement frequency is very high.
The supporting chain wheel in the prior art mainly comprises a tug, a tug shaft, a tug cover, a floating seal seat, a tapered roller bearing, a sealing ring and a check ring. When the riding wheel has abrasion failure, the riding wheel can only be integrally replaced under the influence of conditions such as maintenance personnel technology, tools, operation environment and the like, and a large amount of waste is caused.
