VIBRATING PAVEMENT ROLLER Russian patent published in 2020 - IPC E01C19/28 

FIELD: construction.

SUBSTANCE: vibrating pavement roller comprises a front half-frame, a cylindrical roller, shafts inside the roller, two main unbalance units of common radial vibration, fixed on shafts, axes of which coincide with geometrical axis of roll, unbalances are identically oriented for synchronous operation, rolling bearings, rubber-metal shock-absorbers. In addition, the vibrator is equipped with a second pair of eccentric masses, respectively fixed on coaxial shafts, connected by cardan shaft, additional unbalances are synchronously oriented relative to each other and installed relative to the main pair of eccentric masses with mismatch angle of 90 degrees.

EFFECT: invention relates to rollers for compaction of soils and materials during road construction.
