伸缩减震型汽轮机联轴器罩壳的改进设计

Improved Design of Coupling Casing for Telescopic Damping Turbine

针对汽轮机联轴器罩壳在设计尺寸与安装尺寸出现偏差造成安装不上,现场运行振动导致固定拔合螺栓松动的问题,对联轴器罩壳进行了改进设计。通过把联轴器罩壳分为前后两个部分,并在两部分的接触面上添加0型橡皮垫圈,实现了减震伸缩型联轴器罩壳的改进设计。

In order to solve the problem that the turbine’s coupling casing can’t be installed due to the deviation between the design size and the installation size,and the fixed pulling bolt is loose due to the vibration of field operation,the coupling shell is improved and designed.By dividing the coupling casing into two parts,and adding O-type rubber gasket on the contact surface of two parts,the improved design of the telescopic damping coupling casing is realized.
