An undercarriage includes a plurality of bottom support rollers defining a bottom support roller platform distance and front and rear wheels defining a wheel pitch distance, and a track chain defining a link pitch distance and a ratio of the bottom support roller platform distance to the wheel pitch distance ranges from 0.70 to 0.95 and a ratio of the roller spacing distance to the link pitch distance ranges from 0.75 link pitch distance to 1.50 link pitch distances.

Undercarriage support for a track chain

A sprocket assembly for a track-type machine comprises a plurality of teeth, radially-disposed about a center of the sprocket assembly, each of the plurality of teeth comprising opposing tooth flanks, wherein successive pairs of teeth defines a substantially concave channel for receiving therein a cylindrical pin member associated with a track link member of a continuous track chain, each tooth flank having a tooth angle less than about 17 degrees.

Sprocketed drive assembly for track-type machine

An apparatus and method for reducing vibrational effects of track chain assembly catenary hang is disclosed. A work machine includes a pair of track roller assemblies one positioned on each side of the work machine. The vibration reducing apparatus and method includes repositioning undercarriage components to vary the catenary hang from one side of the work machine to the other.
