Spur and Helical Gear Design
David Brown Santasalo helical gears can offer advantages over spur gears in certain applications. Thrust bearings are required to carry the additional load along the axis of helical gears and a specific lubricant is used to cope with the sliding friction between the meshing teeth.
Lower Lifecycle Cost
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. For critical applications, optional condition monitoring tools enable the performance of a drive system to be followed either in real-time or as a part of regular inspections. If damage to the gear should occur, individual segments can be replaced instead of changing the whole gear, making it possible to carry spare parts.
