发明名称	Tracked mobile machine with star carrier roller and method of assembly
摘要	Star carrier roller assemblies have been used in certain tracked mobile machines, such as those used in the timber industry, that must operate in cold weather and/or over rough terrain. Due to interaction of the star carrier roller assembly with a track chain assembly, undesirable wear on the star carrier roller assembly occurs. The present invention includes at least one star carrier roller assembly for a tracked mobile machine that limits the wear on the star carrier roller assembly. The star carrier roller assembly includes a carrier roller positioned adjacent to a sprocket having a plurality of teeth. Each tooth includes a tooth width and a tooth angle. A ratio between the tooth width and a difference of a pitch length and a bushing diameter of a track chain assembly is less than 0.3, and the tooth angle is greater than or equal to zero degrees (0°). The present invention further limits the wear of the star carrier roller assembly by maintaining a wear surface on the carrier roller less than three hundred degrees Fahrenheit (300° F.) while attaching the sprocket to the carrier roller.
