AN ECCENTRIC-REVOLUTIONARY BODY AND A VIBRATION APPARATUS COMPRISING THE SAME
摘要
<p>The present invention relates to an eccentric rotating body and a vibration apparatus comprising the same. The vibration apparatus of the present invention employs an eccentric rotating body manufactured by integrally machining a cylindrical steel rod. In the present invention, the eccentric rotating body comprises an eccentric rotating body formed of a remainder of about 1/2 to 1/8 of the cylindrical steel rod by cutting out about 1/2 to 7/8 of the cylindrical steel rod at a central region thereof, and upper and lower disk- shaped rotating portions connected to the eccentric rotating portion, so that all of them can be integrally manufactured. In the vibration apparatus of the present invention, the eccentric rotating body is rotated by causing the upper disk-shaped rotating portion to directly receive a rotational force from an electric motor. The rotational force generated from the electric motor can be efficiently used and stable and uniform minute vibration can be generated.</p>
