is a force orientated towards the girth gear), the pinion rollers are permanently in contact with the girth gear tracks. This maintains a constant position of the pinion versus the girth gear, and therefore constant centre distance and alignment. Another set of rollers, mounted in the Bogiflex casing, roll onto two girth gear internal tracks.

Checking Tooth Contact Pattern & Condition of Ring and Pinion

There are two basic types of conditions that will produce ring and pinion noise. The first type is a howl or chuckle produced by broken, cracked, chipped, scored or forcibly damaged gear teeth and is usually quite audible over the entire speed range. The second type of ring and pinion noise pertains to the mesh pattern of the gear pattern.
