The Double Helix torque amplifier has an “unique” planet arrangement that produces efficient load sharing, with levels of strength and stiffness that cannot be achieved by any other any gearbox on the market, says Genesis.

The actuator is aimed, in particular, at robot applications, and will make them safer and more productive, according to the company. The actuator can withstand repeated shock loads from emergency stops and, when paired with the company’s LiveDrive radial-flux motor, delivers high torque at low gear ratios, resulting in a higher throughput than traditional robot designs.

The actuator’s backdrivability allows its torque to be controlled without needing a torque sensor, resulting simple, robust torque control with good safety and controllability.
