Description

Technical Field

[0001] The utility model relates to the technical field of excavator accessories, in particular to a butt-jointed track wheel. Background Art

[0002] The track rollers are used to support the weight of the excavator and roll on the track rails (track links) or track shoes. They are also used to limit the track to prevent lateral slippage. When the excavator turns, the track rollers force the track to slide on the ground. The track rollers are often in mud, water and dust, and are subject to strong impacts, so they are required to have reliable sealing and wear-resistant wheel rims.

[0003] The existing track rollers are limited by their own structure and materials, and their wear resistance and impact resistance are poor. At the same time, they have large friction and noise during use, causing serious wear of various parts of the track rollers, resulting in a short service life and unable to meet the needs of long-term use.
