JG型橡膠剪切隔振器是由內、外鋼套和中間的合成橡膠組成,經硫化呈中空圓錐體,橡膠部份受剪切力,具有較大的變形範圍和較低的固有頻率。工作溫度範圍在-15℃-+80℃。溫度變化時,剛度也有所變化:阻尼比C/C。≥0.07。對於水泵、壓縮機、通風機、發電機組、冷凍機等機械設備的積極隔振和儀器儀表的消極隔振都有良好的隔振效果。
JG rubber shearing vibration absorber is com-posed of outer and inside steel sheath and synthetic rubber in the middle.It is hollow cone after being vulcanized.It is the rubber parts that bears the shear. This type has wide distortion scope and low intrinsic frequency.Working temperature ranges from -15℃ to 80℃.Rigidity changes as the tempera-ture fluctuates.Damp ratio is great and equal than 0.07 .It plays an important role in vibration insulating positively of mechanical equipment like water pump, compressor, ventilator, dynamo, refriger-ator and vibration insulating passively for instru-ment and apparatus.
