a girth gear may not be so intuitive to the manufacturer or to the purchaser. The following sections will describe common girth gear design features, the normal sequential steps in the manufacturing process, some typical challenges encoun-tered along the way, and the downstream effects of failing to manage those chal-lenges. Girth Gear Applications

This gear unit type was developed for driving tube mills with girth gears. Here, the gear unit forms a single unit with the girth gear with which it meshes directly. Compared to the traditional pinion/girth gear variant with external pinion and girth gear, the system with the gear unit for the girth gear is by far more favorable.

Installation process Once the kiln was installed onto its trommel rollers, the girth gear was assembled and clamped onto the kiln body using the clamp-on tool - ing. The girth gear was manufactured in 12 segments. The advantages of this is ease of transport and installation, as well as the possibility to replace one segment, should a tooth fail.

Gear wear is minimised by the use of Austempered Ductile Iron (ADI) in castings. ADI has a high torque/weight ratio, together with increased resistance to fatigue and wear for a longer ring gear life. Highly accurate production and assembly techniques minimise vibration and further enhance the long service life of David Brown Santasalo girth gears.
