ZJD、SD型橡膠隔振墊

ZJD,SD rubbervibration isolation mat

Page18

橡膠隔振墊是根據橡膠動力學特征研製成功的,有圓形凹陷鏤空、瓦楞形、圓柱多點式形等,具有耐油、耐腐蝕、耐老化等性能。一般以剪切形受力為主,具有固有頻率低、結構簡單、使用方便,廣泛應用於各類振動機械設備的隔振降噪,如機床、風機、水泵、空氣壓縮機、冷凍機、柴油機等機械的積極隔振和各類精密儀表儀器、光學儀器的消極隔振,隔振效果明顯。

Rubber vibration isolation mat is developed according to the dynamic characteristic of rubber with different shape like round depressed hollowed—out,corrugated and multipoint columniform.It has the capability of resisting grease,corrosion and aging.It receives shear mainly with the feature of low frequency simple structure and convenient usage.It is widely applied to insulate vibration and reduce noises positively for vibrate mechanical equipment,such as machine tool,fan engine,water pump,air compressor,refrigerator and diesel,is effective in insulating vibration passively for precise instrument and apparatus and optical apparatus.
