Claims (1)

Patent-Anspruch :Patent claim: Einrichtung zur Verhinderung des Dürchhängens länger horizontal gelagerter Bohrwellen, dadurch gekennzeichnet, daß eine oder beide Enden der Bohrwelle über ihre Stützlager hinaus verlängert werden, so daß durch das Gewicht der überhängenden Enden neue Biegungsmomente entstehen, die dem durch das Gewicht des zwischen den Stützlagern befindlichen Teiles der Bohrwelle erzeugten Biegungsmomenten entgegenwirken.Device to prevent sagging longer horizontally stored drilling shafts, characterized in that one or both ends of the drilling shaft are extended beyond their support bearings, so that the weight of the overhanging ends creates new bending moments, due to the weight of the part located between the support bearings Counteracting the bending moments generated by the drilling shaft.
