Eccentric shaft with counterweight

On an eccentric shaft having at least one counterweight (20) which is mounted to the shaft as separate part, the seat of the counterweight on the shaft exhibits a cross-section bounded by two circular arcs. One circular arc (43) which is diametrically opposite to the eccentric (23) has its center on...

Zusammenfassung:	On an eccentric shaft having at least one counterweight (20) which is mounted to the shaft as separate part, the seat of the counterweight on the shaft exhibits a cross-section bounded by two circular arcs. One circular arc (43) which is diametrically opposite to the eccentric (23) has its center on the eccentric axis (41) and the other circular arc (44) has its center on the axis of rotation (42) of the shaft (24). Use of the drive shaft in a displacement machine of the spiral type of construction, in which a displacement body is held on a disk-shaped rotor which can be eccentrically driven with respect to a housing.
