Military Vehicle – Gun Turret Operation is Neeter

Application
Controlled movement of gun turret utilising 8 gearboxes, 4 to control left movement and 4 to control right. High precision and repeatability required, along with high performance and low maintenance.

Solution
Range N, Series 35, Ratio 1:1 gearboxes selected. Units built with minimal backlash to aid with the repeatability and high precision of movement required and filled with high quality lubricant, allowing units to be sealed for life. The compact design of the units kept the whole design into a minimal footprint allowing more room for operators of the turret.
