Abstract
Device for tensioning the transmission belts for the electric drive of tool spindles, characterized in that the transmission from the motor (2) to the spindle (22) is carried out by an intermediate pulley (15) that moves on a displaceable shaft (18) about an eccentric axis (a), the axis of rotation (b) of the intermediate pulley being able to move from outside with respect to the axis (c) of the spindle in such a way that at the same time the belt (14) between the engine and the belt is tensioned. The intermediate pulley, and the belt (20) between the latter and the spindle. (Machine-translation by Google Translate, not legally binding)
