David Brown Santasalo David Brown Santasalo has almost three centuries of gear engineering expertise and a huge installed base of successfully operating girth gears worldwide. Usually fitted to the outside of horizontal mills, rotary mills and kilns, girth gears provide the system's primary rotational drive and as such need to be robust, efficient and built to last. David Brown Santasalo delivers a full range of girth gears with cast, fabricated and multi-segment options available for the following applications: Mills • Kilns • Dryers • Coolers • Scrubbers Key benefits: • Cast and fabricated gears rated up to 10MW per pinion • Options for 2, 4, 6 and 8 segment manufacture in cast and fabricated material • Designed to the latest AGMA standards for complete assurance Individual gears or a fully optimised system Girth gears can be supplied individually, or as part of a fully optimised package which includes: • Mill drive gearbox • Girth gear • Barring drive • Auxiliary equipment including couplings, brakes, pedestal bearings and clutches Whichever option you chose, rest assured that your girth gear will be designed to complement your whole system.

T section gearing options Y section gearing options T section gears are designed to optimise stiffness across the gear’s facewidth. David Brown Santasalo T section gears are resilient to pinion misalignment, ensuring robust, reliable operation. David Brown Santasalo uses Finite Element Analysis (FEA) to deliver optimal gear performance. Y section designs have been extensively used on rotating mills and kilns for many years and David Brown Santasalo has long standing experience in providing this type of girth gear. Y section gears offer optimal rim support and stiffness over the facewidth of the...
