New strain wave gearing for lighter arms

A special feature is the new robolink strain wave gearing, which can be, for example, very easy to use as the sixth axis of the robot arm, that is, as a radial connection between arm and gripper. It is very lightweight and efficient and is offered by igus in two installaiton sizes as a single component, or with a Nema17 or NEMA23 stepper motor. "The strain wave gearing has the advantage that it has minimal backlash and thus ensures a precise adjustment with incredible smoothness," explains Martin Raak, robolink product manager at igus. "It is very compact and has a high transmission ratio." The gearbox consists of an outer ring gear and a flexible wear-resistant inner ring gear made of iglidur high-performance plastic.

Quick and easy to configure with new online tool

The worm wheels for the new transmission ratios 1:30 and 1:70 of the robolink D worm gear also utilise iglidur materials. For these, igus now also offers a decoupled option of motor and joint. The two components are connected to each other by an aluminium profile - the result is a better weight distribution on the axis, whereby more load can be lifted. The new universal gripper adapter allows the attachment of different grippers on the robolink D joints. The robolink D modular kit is rounded off with a new online configurator, by which users can assemble their robolink D joints from the start of the Hannover Messe and thus can configure their low priced robotic arms.
