Flail Assembly

Gearbox to drive the flail assembly of land mine clearance vehicle.

Application Details

Range N, Series 40, Ratio 2:1 bevel gearboxes selected. The unit was selected for its compactness for mounting in the flail drive, however the unit needed greater power than the current designed unit. Up rated gears designed and fitted to the unit. Unit design also capable of great shock loads.

M777 Howitzer Gearbox

M777 Howitzer

Two of the bevel gearboxes are power driven and the third is used as a hand wind facility, all units are used in the elevation of the gun, prior to its use.

Application Details

The Howitzer had been in development for over 3 years and a further 5 years working closely with BAE Systems (VSEL) to ensure that the units meet the design requirements. Developed with BAE with extensive testing and trials.

Three units are supplied per Howitzer, each one different, two are based upon the standard N35 gearbox design and the third is a bespoke design based around a set of N35 gears. Many different prototypes were manufactured and tested in vigorous terrain and weather conditions, each design slightly different until the final design was settled upon.
