Seismic Isolation Drive Part With Rolling Part With Friction Force Reinforcement Coated Rolling Surface
Updated 9 months ago
Abstract
Disclosed is a seismic isolation device having a ball (ball transfer) and a rolling part where the ball rolls which performs a seismic isolation function wherein the rolling part is entirely formed of a hard material so as to support a heavy load and the hardness of the material of the rolling part reduces a friction force so that the ball has a relatively greater displacement of rolling compared to seismic intensity. However since the rolling space of the ball cannot be extended infinitely in most cases a customer wants to be provided with a seismic isolation device which has a rolling part with a small radius while withstanding a large earthquake. This phenomenon is clearly shown especially in a seismic isolation device for a computer using a cable which should secure a cable insertion space. The present invention relates to a technique of coating the surface of the hard rolling part with a material of great friction force to be joined together with a rolling surface thereby supporting a heavy load and greatly increasing a friction force.
