FIELD: machine building.SUBSTANCE: mechanism includes a housing, an input shaft and an oscillatory shaft that is perpendicular to it, which are installed on bearings in the housing, as well as wobble plate mechanism. The latter includes a bell crank, which is put on trunnions of input shaft, forced inclination angle variation device of bell crank relative to the axis of input shaft, and a wobble plate forming together with the bell crank a rotating pair. A support fork interacting with the wobble plate by means of trunnions is installed in the housing with possibility of rotation. Oscillatory shaft is provided with a balance arm, and wobble plate is provided with a tubular guide having the possibility of being rotated and crossing the bell crank axis at right angle; a ball roller is arranged in the above guide and forms a back-and-forth pair together with the balance arm.EFFECT: simplifying the design and improving operating characteristics of the mechanism.16 dwg |
