An elastic transmission element is part of a strain wave gear. Such strain wave gears are also referred to as Harmonic Drives. The elastic transmission element is also referred to as a flexspline and has an outer toothing (). The elastic transmission element is equipped with at least one strain gauge () for measuring a mechanical strain on the elastic transmission element. The one strain gauge () or the plurality of strain gauges () extends at least as a whole about a circumference of a lateral surface or an axial lateral face of the elastic transmission element.

Strain wave gear and transmission element for same, robotic arm and method for measuring a torque

A planetary gearing for a robot gearing arrangement includes a sun gear, a ring gear, and a planet carrier with at least three planetary gears rotatably mounted thereon. The planetary gears are arranged on planet pins arranged perpendicular to the planet carrier and are in meshing engagement with the sun gear and the ring gear. At least one first planetary gear is biased in a first circumferential direction and/or at least one second planetary gear is biased in a second circumferential direction. A first planet pin of the first planetary gear is at least partially elastically deformable in the second circumferential direction and/or the second planet pin of the second planetary gear is at least partially elastically deformable in the first circumferential direction.
