美国的Vibratech公司是一家生产控制振动和冲击的减振器主导厂商，它可以提供满足GE公司各种机车柴油机曲轴需要的粘性减振器。该公司生产的粘性扭振减振器可以减轻各种内燃机固有的曲轴振动。通过控制这些“挠曲”振动，Vibratech减振器可以防止柴油机曲轴、凸轮轴、正时齿轮 Vibratech, a U.S.-based manufacturer of shock absorbers that control vibration and shock, offers a viscous damper that meets the needs of GE’s various locomotive diesel crankshafts. The company’s viscous torsional vibration damper can reduce the inherent crankshaft vibration of various internal combustion engines. By controlling these “flexural” vibrations, the Vibratech shock absorbers prevent diesel crankshafts, camshafts, timing gears
