The strainwave gearing is claimed to feature minimal backlash, ensuring precise adjustment and smoothness. It is also compact and has a high transmission torque ratio. A typical application would be as the sixth axis of a robotic arm, that is, as a radial connection between arm and gripper.
The worm wheels for the new transmission ratios 1:30 and 1:70 of the robolink D worm gear also use iglidur materials. For these, igus offers a decoupled option of motor and joint. The two components are connected to each other by an aluminium profile which is said to result in better weight distribution on the axis, enabling heavier loads to be lifted. The new universal gripper adapter allows the attachment of different grippers on the robolink D joints.
An online configurator allows users to configure and assemble custom robolink D joints. Motors, encoders, cabling, and other accessories are also available.
