用作粘性减振器的工作流体硅油,由于油性恶劣,致使减振器外壳与惯性轮之间滑动部位的油膜易于破裂而常常出现“咬死”现象,减振器的耐久性因此而受到显著削弱。为了克服上述缺点以改善粘性减振器的耐久性,最近设计的粘性减振器,把以往结合在一起的具有振动阻尼作用的工作油部分与封于外壳内的惯性轮安装位置的滑动部分,设计成彼此独立的型式,并制造了样机。为了检验这种减振器的特性,将它装在实机上进行了扭振洲试,并且对设计这种减速器的方法作了探讨。
As the working fluid of viscous vibration damper, the oil of silicone oil, which is easy to rupture at the sliding part between the shock absorber shell and the flywheel due to poor oiliness, often appears “bite dead” phenomenon. Therefore, the durability of shock absorber Have been significantly weakened. In order to overcome the above drawbacks and to improve the durability of the viscous vibration damper, the recently designed viscous vibration damper is composed of a previously-joined portion of the working oil having a vibrational damping function and a sliding portion enclosed in a mounting position of the flywheel in the housing, Designed to be independent of each other and prototype. In order to test the characteristics of this shock absorber, it was installed on the real machine torsional vibration test, and the design of this reducer method were discussed.
