Abstract

방진 고무는, 통모양의 엘라스토머와, 금속등으로 이루어진 통모양의 내측고정부재 및 외측고정부재로 구성된다. 내측고정부재 및 외측고정부재에는 플랜지부가 형성되어 있다. 외측고정부재 보다 지름이 작은 내측고정부재는, 엘라스토머의 내경쪽에 고정되고, 외측고정부재는 엘라스토머의 외경쪽에 고정되어 있다. 엘라스토머는 열전도율이 1.3×10-3~7.1×10-3cal/cm.sec.℃이거나 또는 고무 100 중량부에 대하여 흑연 50~200 중량부를 함유하는 고무 조성물로 이루어진다. 이러한 방진 고무는 방진효과를 저하시키지 않고 축에 직각방향의 스프링 정수를 크게 할 수 있어, 모터의 변위를 작게하여 위치결정의 정밀도를 향상시킬 수 있다. 또 모터에서 발생한 열을 효과적으로 방열시킬 수 있어, 모터의 온도상승을 억제할 수 있다.
