HYDRAULIC VIBRATION EXCITER

摘要

FIELD: vibration devices used in construction and mining industry. SUBSTANCE: unbalanced cylindrical rotor is positioned in vertical partitions of body through radial hydrostatic bearings. Vibration exciter is provided with system of forced pumping of working fluid from cavity of body. Rotor drive is made in the form of Pelton-type turbine wheel and nozzle communicating with external pressure source by means of pipeline. Stable position of rotor depends on two hydrostatic thrust bearings. EFFECT: adaptation of rotor supports to load variation. 4 cl, 7 dwg
