VIBRATORY ROLL OF ROAD ROLLER Russian patent published in 2020 - IPC E01C19/28 

FIELD: road-building machines.

SUBSTANCE: invention relates to road-building machines and is intended for compaction of road surfaces, bases and soil. In vibratory roll of road roller, roll is mounted on journals of rotary frame, which is installed on roller frame and represents rectangular box-shaped design, and on rotary frame there are two unbalance shafts, axes of which are offset relative to rotational axis of roll in diametrically opposite sides at equal distances. To transmit directed oscillations to the roll, unbalance shafts with unbalances fixed on them have the possibility of rotation in the opposite direction due to the hydraulic motor installed on the roller frame, drive shaft, toothed and toothed belt transmission with transmission ratio equal to 1 for each gear. For rapid change of direction of forced force vector created by unbalances, rotary frame has the possibility of changing its position due to hydraulic motor and worm reduction gear installed on the frame of the motor, low-speed shaft of which is equipped with a rotation angle sensor.

EFFECT: high efficiency of the process of compaction of a road surface by a roller of a roller.
