This invention concerns a stress test rig consisting of a rigidly mounted part, which contains the devices uniformely used for all types of test gears, and an assembly truck (37), which holds the test gear (16) and the required adapter devices. A test rig gear unit (2) forms a continuous stress circuit with a superimposed gear unit (9), an adaptation gear (23), and a second test rig gear (19). The stress moment is set by a control unit (15) through the superimposed gear unit (9). The regulation variable for the stress moment is determined up to more than 80 % by a neuronal network (31). The test rig gear unit (2) is a conical gear wheel and the superimposed gear unit (9) has a conical gear step (13), so that the output shaft (14) of the superimposed gear unit (9) is pivoted and has a height adapted to an input shaft of an adaptation gear unit (23) or of a test gear unit (16).
