Umlaufbiegepruefmaschine zum Einleiten eines Biegemomentes in einen Pruefling

The description refers to a rotating bending fatique test machine for applying a rotating bending torque to a test object. The bending torque is produced by a rotating unbalanced weight in a rotating mounting and arranged at the end of a shaft part opposite to the test object. The test object is fixed to the shaft part on the one hand and to the machine frame on the other hand. There is a balancing weight which rotates about the same axis of rotation and at the same speed as the unbalance weight. The drive shaft drives the two weights simultaneously. The balance weight (6) is offset in the planar rotation of the unbalance weight (5) by 180<degrees>, arranged on an overhead mounted hollow shaft and mounted directly on the machine frame (7).
