Beschreibung
Zusammenfassung:	FIELD: drilling of oil and gas wells by percussion methods. SUBSTANCE: invention is related to fixtures designed for vibratory action of drilling tool. Given mechanism comprises hollow cylindrical body, vortex member coming in the form of tangential branch pipe opening into vibration chamber in which vibration space ball mass travels freely. Vibration chamber is positioned in symmetry and perpendicular to axis of mechanism and presents ball truncated by frontal limiters possessing holes in central parts. Angle of inclination of tangential branch pipe with axis of mechanism equals angle of inclination of generating lines of conical expansion of internal space of substitute and is found from mathematical expression. Vibration chamber is made fast in upper part with the help of horizontal plate and with the aid of vertical plate in lower part. Radius of ball mass is determined by mathematical formula. EFFECT: raised drilling effectiveness and operational reliability. 4 dwg
