FIELD: mechanical engineering.
SUBSTANCE: invention relates to mechanisms for converting rotation of drive shaft into vibration of driven shaft with steplessly changing amplitude and it can be used in non-friction variable-speed drives, positive displacement adjustable hydraulic machines and other devices. Proposed mechanism contains control handle, driving and driven shafts installed in housing on bearings, and device converting unidirectional rotation of drive shaft into vibratory rotation of driven shaft with possibility of changing swing by control handle, including tilted crank installed on trunnions of driven shaft and mechanically coupled with driving shaft. Mechanism is provided with carrier made on driving shaft and bevel gear wheel mounted in housing for turning by control handle and planet pinion also installed on carrier, hinge coupled with tilted crank and forming internal engagement with bevel gear wheel. Number of teeth of plant pinion is half as much as that of wheel.
EFFECT: improved service characteristics, simplified design, reduced cost.
