Description

Technical Field

[0001] The utility model relates to the technical field of excavator accessories, in particular to a firmly installed supporting wheel. Background Art

[0002] The supporting wheel of the excavator is also called the supporting sprocket. It plays the role of supporting the crawler chain rail and maintaining the linear motion of the chain rail. There is sealed lubricating oil inside the supporting sprocket. The crawler chain rail is placed on the outer jacket of the supporting sprocket and can rotate around the central axis. The central axis can be fixed during installation. If the supporting sprocket is damaged, the crawler track cannot keep moving in a straight line, which is bound to affect the work efficiency. When the sprocket is loose, it will cause the crawler track to make a sound of wear. Therefore, the stability of the supporting sprocket installation directly affects the service life of the supporting sprocket.

[0003] At present, when installing the supporting wheel and the crawler chain rail, the crawler chain rail is usually directly mounted on the surface of the supporting wheel to achieve the purpose of installation. However, in the actual operation, since the lengths of the crawler chain rails are different, the supporting wheel can only be adapted to the crawler chain rails of a limited size for use, and the size of the supporting wheel cannot be adjusted according to the size of the crawler chain rail. There are certain limitations in use, which brings troubles to users.

[0004] Therefore, we offer a securely mounted support wheel. Utility Model Content
