Rolls-Royce is introducing a new generation of gearboxes. The 950AGHC, depicted here in its horizontally offset version, is the second in a planned series of five models (Credit: Rolls-Royce).
Rolls-Royce is rolling out a new
generation of marine reduction gearboxes developed by its Norwegian technicians. The latest addition to the range, the 950AGHC, has a rated input torque of 130kNm and up to 530kNm of output torque, and is the second model of the new series to be released, following the 2008 launch of the size 550 gearbox. For the 950AGHC, the maximum reduction ratio is 6.3:1, and a secondary power take-off with either vertical or horizontal offset can be specified. Tree more sizes, 1050, 850 and 650,
are to be brought to the market in due course, while three of the previous series will be retained, so that the eventual range will cover torque ratings from 90kNm to 1200kNm.
being approached by naval architects and specialist builders to provide propulsion solutions for large yacht applications. Having made substantial investments
in new conventional and CNC (computer numerically-controlled) lathes during
2007 and 2008, Stone Marine Singapore is currently installing two additional, oil-fired furnaces to increase capacity by 50%. Tis will also enable the company to manufacture than hitherto.
