Compact gears deliver high power output
03 May 2016
Designed to fulfil the growing need in robotics and broadcast sectors for lightweight, compact gears that can deliver a high power output, Harmonic Drive UK has launched the new CobaltLine Series, a series of high torque gear component sets and gear units. CobaltLine also features an extended temperature range and higher peak torques compared to the standard HFUC series.
The CobaltLine Series Gears are available in six sizes, with gear ratios of 50, 80, 100, 120 and 160:1, offering repeatable peak torques from 23 to 841Nm and a power density of up to 545 Nm/kg.
Harmonic Drives are favoured in robotic and broadcast applications for their high accuracy, repeatability and low weight. Robots used in applications ranging from semiconductor manufacturing and industrial automation, as well as military and defence demand very high repeatability levels. With a zero backlash design, CobaltLine achieves repeatability to within ± 6 arc seconds.
The CobaltLine Series Gear Units also feature improved corrosion resistance on the output bearing for environments with high humidity levels and the range can operate in ambient temperatures between -40 and 90 degrees Celsius by careful selection of specialised lubricants optimised for harsh environments.
