ROLL OF ROAD ROLLER Russian patent published in 2005 - IPC

FIELD: road building.

SUBSTANCE: invention relates to road facilities for compacting road-building materials, namely, rollers used for layer-by-layer compacting of preliminarily graded earth and gravel-and-crushed stone materials when building motor roads and other like constructions. Invention provides simplified design and improved reliability of roller owing to reduction of number of drive and support rollers in roll of road roller containing shell accommodating frame with fitted-on three rollers installed for contact with inner surface of shell. Axes of rollers are parallel to axis of shell and they form in plan isosceles triangle whose base is formed by two coaxial rollers. Base and apex of triangle are located at different sides from vertical longitudinal plane of shell. Height l_x of isosceles triangle formed by rollers is l_x=(0,5...1,2)R of radius R of shell, and base l_y of triangle is l_y=(0,7...1,4)R of radius R of shell. Shell is made of e4lastic material. At least one roller can be furnished with eccentric axle and axle rotation drive. Roller arranged in vertical cross plane of symmetry of shell can also be furnished with eccentric axle and axle rotation drive. Eccentric axle rotation drive can be made in form of hydraulic drive including hydraulic motor whose shaft is connected with eccentric axle of roller.

EFFECT: simplified design, improved reliability.
