FIELD: mechanical engineering. ^ SUBSTANCE: mechanism comprises control handle, driving and driven shafts mounted in the bearings of the housing, and device for converting rotation of the driving shaft into vibration rotation of the driven shaft, with vibration amplitude being changed by means of the control handle. The device has intermediate vibration shaft that is mounted in the bearing inside the housing and provided with the eccentrically mounted ball bearing and connected with the driving shaft for permitting rotation vibration with a constant amplitude, plank with the slot mounted in the ball bearing and pivotally connected with the housing, and bushing set in the slots of the driven shaft and provided with the pin mounted in the slot of the plank. The control handle is kinematically connected with the bushing for permitting movement of the driven shaft along the bushing. ^ EFFECT: simplified structure and reduced cost. ^ 8 dwg |
