COMBINED ROLL OF VIBRATING ROLLER Russian patent published in 2019 - IPC E01C19/28 

FIELD: technological processes.

SUBSTANCE: invention is intended for the compaction of materials from which soil and concrete structures are erected. In the combined roll of the vibratory roller, containing a central unbalance shaft 1 with a gear wheel fixed on it, which engages with gear wheels of twice the diameter and fixed on two satellite unbalance shafts 3, whose axes are symmetrical to the axis of the drum, on the central unbalance shaft 1 there are two unbalance sleeves 2 placed symmetrically to the center of this shaft, with gears attached to them, connected by chain gears with gears twice the diameter, fixed on the satellite unbalance shafts 3 so that with multidirectional orientation of the unbalances of satellite shafts 3, the unbalances of sleeves 2 and central unbalance shaft 1 are oriented vertically upwards.

EFFECT: invention is aimed at reducing energy consumption for material compaction, at increasing productivity and reducing the weight of the vibrating roller.
