Arrangement, in particular testing device, having a geared motor, a solid shaft and gear mechanisms

An arrangement, in particular testing arrangement, having a geared motor, a solid shaft and gear mechanisms, in particular gear mechanisms functioning as test specimens, wherein each gear mechanism has a hollow shaft, in particular a hollow shaft which passes through the gear mechanism, wherein each gear mechanism has a further shaft, in particular an input shaft, wherein the solid shaft is respectively connected in a rotationally fixed fashion to the hollow shafts of the gear mechanisms, wherein a first of the gear mechanisms has a torque flow from the further shaft to the hollow shaft, in particular therefore is operated as an input gear mechanism, wherein the other gear mechanisms each have a torque flow from their respective hollow shaft to their respective further shaft, in particular that is to say are driven in each case in a retrodriving fashion.
