Abstract

A belt tensioning device for traction mechanisms includes a receiving and mounting housing, a pulley carrier pivotally connected to the receiving and mounting housing, a bearing supporting the pulley carrier relative to the receiving and mounting housing, and a spring located between the pulley carrier and the receiving and mounting housing for applying the tensioning force. The belt tensioning device, in normal operation, on the slack side between a generator and a main pulley can also be used when the slack side becomes the load side by a blocking mechanism which enables swinging motion of the pulley carrier relative to the receiving and mounting housing in a first direction, and limits or prevents such motion in a second, opposite direction.
