Abstract (en)
[origin: EP0088071A2] 1. Orbiting mass device for generating vibrations, in particular for road rollers, comprising a rotatably drivable shaft (5), at least one flyweight (8) being drivingly connected with said shaft, a retainer (9) being rigidly connected with the flyweight (8) and located at the opposite side of the shaft (5), whereat the eccentricity of the total gravity center of the rotating masses is displaceable continuously during rotation by an actuating means located outside of the roller body (2), and the flyweight (8) is guided at the shaft (5) axially immovable and radially displaceable, characterised in that two wedges (18, 19) cooperating with the flyweight (8) and arranged at an axial distance from each other are arranged on the shaft (5) axially movable, said wedges (18, 19) being rigidly connected with each other, preferably by rods (26) extending axially, the wedging surface (24, 25) of each wedge (18, 19) being formed by the base of a recess (23) in the circumference of a plate (20, 21), the borders of which recess embrace the retainer (9), and the retainer having the complementary wedging surfaces (16, 17).
