Structural form and working principle of excavator track rollers
Als tragendes Hauptbauteil von Raupendrehbohrgeräten, insbesondere bei Raupendrehbohrgeräten mit großer Tonnage, Die Design- und Fertigungsqualität von Schienenrädern steht in direktem Zusammenhang mit der Gesamtsicherheit der Bohranlage. Die Arbeitsbedingungen von Raupendrehbohrgeräten sind komplex. Unter bestimmten besonderen Hebe- oder Auslegerbedingungen, nur ein Teil der Schienenräder wird beansprucht.
Deswegen, die Anordnung der Schienenräder ist in der Mitte spärlich und an den Enden dicht. Um den Anforderungen der Raupenkette gerecht zu werden, nimmt das Gewicht der Drehbohranlage allmählich zu, the number and structural parameters of the track wheels increase accordingly. The track wheels are installed at the bottom of the track frame and roll with the bottom surface of the belt plate when walking. The installation form is often open in small tonnage. Type, closed structure is adopted in large tonnage.
Quality requirements for excavator track rollers
Excavator rollers are one of the important accessories of the excavator. They are used to support the weight of the excavator while rolling on the guide rails (Eisenbahnverbindungen) or track decks of the crawler tracks. They are also used to limit the crawler tracks and prevent lateral slippage. . The track wheels force the tracks to slide on the ground as the excavator turns. Excavator rollers are often exposed to mud, water, and dust, and are subject to strong impacts. Deswegen, they are required to have reliable sealing, verschleißfeste Felgen, und geringer Rollwiderstand.
Common problems with excavator track roller
1. The excavator roller body is worn.
The reason for this situation is that the steel used is unqualified or the hardness of the material during heat treatment is low and the wear resistance is insufficient;
2. The excavator roller is leaking oil.
The supporting wheel shaft is constantly rotating through the bushing, and the wheel body needs to be lubricated with oil. Jedoch, if the sealing ring is not good, oil leakage will easily occur. In this way, the shaft and bushing will easily wear without lubrication, causing The product cannot be used.
