Die Folgen von Schäden an der Laufrolle des Komatsu-Baggerzubehörs

Die Gewichtslaufrolle des Baggers trägt das Gewicht und die Betriebslast des Baggers selbst, und die Eigenschaft des Gewichtsrads ist ein wichtiger Maßstab zur Messung seiner Qualität. Was sind dann die Folgen des Schadens an der Laufrolle des Komatsu-Baggers?? Was ist die Schadensursache??

Wenn der Bagger ausfällt, we need to check the partially damaged Excavator SK60 track roller/ bottom roller and find that the main fault is the damage of the spindle, wheel body and oil leakage. Darunter, the main shaft of the severely damaged lower roller appears to hold the shaft, causing the whole track roller to be unable to rotate.

There are two reasons for the oil leakage of Komatsu excavator track roller: Erste, Die Excavator R60 track roller/ bottom roller is immersed in water for a long time during excavator operation, resulting in corrosion of the floating seal ring and O-ring ring groove; The second is construction in mud water in winter, resulting in icing failure of the floating seal ring.

The wheel body of the Komatsu excavator track roller is supported by the upward support of the caterpillar chain rail, and the two ends of the spindle bear the gravity of the excavator. The gravity of the excavator is transmitted to the main shaft through the track frame, outer cover and inner cover, to the shaft sleeve and wheel body through the main shaft, and then to the chain rail and track plate through the wheel body.

When the excavator works in the uneven site, it is easy to cause the track plate to tilt, resulting in the chain rail tilt. When the HD450 track roller does the steering action, the axial channeling power will be generated between the main shaft and the wheel body. Due to the complex force of the Komatsu excavator track roller, its structure must be reasonable, and the spindle, wheel body and shaft sleeve need to have relatively high strength, toughness, wear resistance and sealing.

The consequences of the damage of the Komatsu excavator track roller need to be judged according to the damage situation, and different causes of damage may cause different consequences, but in order to ensure better use, we need to do a good job of daily inspection and maintenance work to reduce the probability of damage.
