Gear system handles twice the bearing load
A novel integrated gear and preloaded output bearing unit provides higher bearing load capacity with significantly improved concentricity and runout tolerances than competing devices.
Small claims for servo actuator
A device believed to be the world's smallest servo actuator is capable of delivering 1.8Nm of torque from an integrated AC motor, gearbox and encoder that measures just 50mm3 in size and weighs 0.4kg.
Harmonic Drive precision gears have been designed to achieve a mean time between failures (MTBF) in defence applications of more than 500kh, with an extremely low failure probability.
Furthermore, Harmonic Drive gears and actuators provide positional accuracy of less than 1arc-min and a repeatability of just a few seconds of arc, making them suitable for use in defence applications requiring high pointing accuracy and high tracking accuracy.
Harmonic Drive technology is being used in a wide range of defence applications including onboard the new Joint Strike Fighter, which incorporates active pilot inceptors providing force-feedback to the operator.

Hollow-shaft servo actuators boast top torque
A new range of compact hollow-shaft servo actuators are designed to offer exceptionally high levels of transmission accuracy and acceleration torque.
Harmonic Drive gears are used in all three axes equipped with active control technology.
Of particular focus on the stand will be the Harmonic Drive range of HFUC component sets, which are ideal for defence applications as they offer a combination of low weight, compact dimensions, high torque capacity, exceptional repeatability and positioning accuracy and can be used in a wide range of operating temperatures.
Typical applications for the HFUC components sets are varied and range from weapon systems, azimuth and elevation axes for artillery and tank guns, camera systems onboard helicopters and cargo landing systems for aircraft.
The new HFUC component sets incorporate a shortened Flexspline, resulting in a significant reduction of the axial length.
Furthermore, the new component sets feature high performance IH tooth profiles to provide increased torque capacity in comparison to standard gears that incorporate traditional involute gear tooth profiles.
The HFUC range is available in 15 gear sizes from 8 to 100, with a choice of gear reduction ratios, from 30:1 up to 160:1.
In addition, the HFUC component sets feature the optimised design of Flexspline, Circular Spline teeth and Wave Generator bearing, to eliminate completely the effects of backlash, provide high torsional stiffness and offer a range of output torque capacities from just 0.9 to 3550Nm.
