Abstract

The present invention relates to a seismic isolating technique, and more particularly, to a ball bearing-type seismic isolator with a conical groove to be installed beneath heavy equipment to prevent the equipment from being turned over upon the occurrence of an earthquake. The seismic isolator of the present invention comprises: a lower plate, the upper surface of which has a lower sliding groove; an upper plate with an upper sliding groove opposite the lower sliding groove; and a ball interposed between the upper plate and the lower plate so as to be brought into rolling contact with the upper sliding groove and the lower sliding groove. The upper sliding groove and the lower sliding groove are formed into conical shapes with the same tilt angle, and each of the surfaces of the upper and lower sliding grooves brought into contact with the ball and the ball have a plurality of stopper grooves or stopper protrusions formed at a predetermined spacing. The seismic isolator of the present invention prevents a structure or the equipment installed thereon from being inclined even upon the occurrence of external vibrations such as those from a strong earthquake, thereby reducing the risk of damage caused by the rollover of the structure or the equipment. In addition, the seismic isolator of the present invention increases frictional resistance between the ball and the sliding grooves to provide constant rolling contact therebetween, thereby preventing the upper and lower plates from being inclined even upon the occurrence of external vibrations such as those from a strong earthquake, and quickly stopping vibrations by the loss of energy caused by the frictional force.
