SELF-PROPELLED VIBRATING ROLLER WITH EXCITER OF COMBINATION EFFECT Russian patent published in 1997 - IPC

FIELD: machines for compaction of pavements, bases and grounds. SUBSTANCE: self-propelled vibrating roller has articulated frame, drive and rolls. One roll accommodates three exciters of circular vibrations. Shafts of two vibration exciters are displaced from the roll rotation axis to opposite sides through 0.5-0.75 of the roll radius. The third vibration exciter is installed for rotation to the side opposite to the side of rotation of the first two vibration exciters. Unbalanced mass of the third vibration exciter is displaced through 90 deg relative to unbalances mass of the first and second vibration exciters. Torque from hydraulic motor may be transmitted to the third vibration exciter through splined coupling and from it through gearings to the other vibration exciters. EFFECT: higher efficiency. 2 cl, 3 dwg
