The Defense Industry considers gears as important and crucial components that drive high-tech weapons systems. Therefore, the Defense Industry requires the best-machined gears that are tough, durable and all weather. Gears find many applications in the Defense Industry including: Casing – uses a single output gearbox with an inbuilt mini core oil passages and an integral oil reservoir. Epicyclic Gear Box – used in torpedo for power maintained gear change. Chassis & Automotive Systems (CAS) – uses running gears with integrated fuel system, hydro pneumatic suspension in battle tanks. Automatic Transmission – use modern epicyclic gear trains along with a torque converter having a bypass clutch. Fighter planes – use actuator gear systems and subsystems in the landing gear system and in the motion control system of the plane to make movements more accurate, predictable and precise. Other specific defense industrial requirements use specialized bevel gear sections of high quality.
