Title:
SEISMIC ISOLATION DRIVE PART WITH ROLLING PART WITH FRICTION FORCE REINFORCEMENT COATED ROLLING SURFACE
Document Type and Number:
WIPO Patent Application WO/2017/014520
Kind Code:
A1
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.
