Gears get going when the going gets tough

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 545Nm/kg.

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.

Graham Mackrell, managing director of Harmonic Drive UK, comments: "The CobaltLine Series Component Sets are made up of only three parts and offer ultimate flexibility in design freedom to achieve the most lightweight, compact solution. The CobaltLine Gear Units incorporate a high capacity output bearing, and can include a large hollow shaft at its core, making it easy to pass through power, data and optical cables without restricting rotational movement. This results in an improved product life and much greater ease of use."

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°C by careful selection of specialised lubricants optimised for harsh environments.
