Vibration Apparatus for Generating Spheroid Wavelength

Abstract

Disclosed is a vibration apparatus for generating a spheroid wavelength by eccentrically rotating a rotation shaft using an eccentric weight. The vibration apparatus includes: an electric motor for generating rotation force; a bracket coupled to a coupling member on the upper portion of the electric motor and having a thru-hole formed at the center portion of the bracket, through which the rotation shaft of the electric motor extends; a cylindrical support member coupled to the edge of the bracket at a lower surface of the cylindrical support member; an eccentric weight coupled to the rotation shaft extending through the bracket and eccentrically rotating on the bracket so that the rotation movement of the rotation shaft is converted into three-dimensional movement generating the spheroid wavelength; and a vibration plate coupled to the upper portion of the cylindrical support member and receiving through the rotation shaft the three-dimensional movement caused by the eccentric rotation of the eccentric weight, for generating the spheroid wavelength. The vibration apparatus can restrain the shaking of the vibration apparatus caused by the three-dimensional movement due to the eccentric rotation of the eccentric weight, and maintain the stability of the rotation shaft so that a vibration plate generates the spheroid wavelength effectively when the eccentric weight rotates.
