The present invention refers to a toothed-belt and V-belt for treadmills, comprising an endless belt, which is provided with a plurality of tread lamellae and which is guided around two deflection pulleys. At least one of the deflection pulleys comprises a sliding disk member and a toothed-disk member in juxtaposition, and the belt comprises, in juxtaposition, a toothed-belt area associated with the toothed-disk member of the deflection pulley and a V-belt area abutting on the sliding disk member of the deflection pulley. The main force for driving the belt is transmitted via the sliding disk member and the V-belt area. The toothed-disk member of the deflection pulley preferably has toothed areas and toothless areas, which are alternately and equidistantly arranged throughout the circumferential surface thereof.
An assembly for treadmills, comprising at least one endless belt, which is provided with a plurality of tread lamellae and which is guided around two deflection pulleys arranged one behind the other, characterized in that at least one of said deflection pulleys comprises a sliding disk member and a toothed-disk member coaxially aligned and in juxtaposition, and that the belt comprises, in juxtaposition, a toothed belt area associated with the toothed-disk member of the deflection pulley and a V-belt area abutting on the sliding disk member of the deflection pulley, the main force for driving said belt being adapted to be transmitted via said sliding disk member and said V-belt area.
An assembly for treadmills, comprising at least one endless belt, which is provided with a plurality of tread lamellae and which is guided around two deflection pulleys arranged one behind the other characterized in that at least one of said deflection pulleys comprises a sliding disk member and a toothed-disk member coaxially mounted on a drive shaft and in juxtaposition, and that said at least one belt comprises, in juxtaposition, a toothed-belt area associated with said toothed-disk member of said deflection pulley and a V-belt area abutting on said sliding disk member of said deflection pulley, the main force for driving said at least one endless belt being adapted to be transmitted via said sliding disk member and said V-belt area.
