Directional-action mechanical vibrator and a mechanical system for converting rotary motion into reciprocating motion

Abstract

The directional-action mechanical vibrator comprises a housing which accommodates a shaft carrying a number of inertia masses arranged eccentrically thereon, said shaft being linked to a power drive, and a rod is adapted to impart motion to the mass being vibrated which is mounted on a support. The shaft has a crank, and the rod is articulated, through one of its ends, to the crank, and through the other end, to the mass being vibrated, whereas the housing is linked to the support of the mass being vibrated through the hinge joint, and the axis of the shaft is parallel to the axis of the hinge joint. The mechanical system for converting rotary motion into reciprocating motion incorporates said mechanical vibrator and a power drive kinematically associated with said vibrator and comprising an electric motor with a pulley set on the motor shaft, and another pulley is set on the vibrator shaft. The drive pulley is offset with respect to the axis of said shaft in a direction diametrally opposite to the crank a distance approximately equal to the oscillation amplitude of the axis of the vibrator shaft which provides for stabilization of the oscillation amplitude of the mass being vibrated and adds to the operating reliability of the power drive of the machines that make use of the said mechanical system.
