摘要：
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 (03). The elastic transmission element is equipped with at least one strain gauge (04) for measuring a mechanical strain on the elastic transmission element. The one strain gauge (04) or the plurality of strain gauges (04) extends at least as a whole about a circumference of a lateral surface or an axial lateral face of the elastic transmission element.
