柴油发电机组的扭转减振器作用

作者:康明斯发电机厂家 发布日期:2016-12-14 来源:www.0755fdjz.com 点击:

 柴油发电机组为消除曲轴扭振,康明斯柴油机在曲轴前端安装扭转减振器,减振器的选用是根据柴油机的额定功率和额定转速来确定的。B、C系列采用橡胶扭转减振器,N、K系列采用硅油扭转减振器。减振器能使曲轴的扭转幅限制在0.2°的范围内。带轮和减振器用螺钉固定在一起。在康明斯N、K系列柴油机上的减振器上刻有气门和喷油嘴进行调整所必需的记号,装配时不能错位,必须对正。有些康明斯柴油机还装有2个减振器即双减震器。 

橡胶扭转减振器的壳体与曲轴连接,减震体壳体(轮毂)与建真题的惯性质量块黏结在硫化橡胶层上。柴油机工作时,减振器壳体与曲轴一起振动,由于惯性质量滞后于减振器壳体,因而在两者之间产生相对运动,使橡胶层产生变形,振动能量被橡胶的内膜擦阻尼吸收,从而使曲轴的扭振得以消减。
硅油扭转减振器由钢板冲压而成的减振器壳体与曲轴相连。侧盖与减振器壳体组成密闭腔,其中滑套与密闭空腔之间留有一定的间隙,里面充满了高粘度硅油,柴油机工作时,惯性盘与减震器壳体间产生相对运动,曲轴的振动能量被硅油的内摩擦阻尼吸收,使扭振减轻。
