轴承刚性对汽轮机轴系振动的影响

Affection Caused by Rigidity of Bearing on Oscilation of Bearing System Used in Steam Turbine

结合中国铝业股份有限公司中州分公司1号汽轮发电机组轴承横向振动的实例,分析了轴承座刚性对机组振动的影响,介绍了从安装角度提高轴承刚性的方法,从而消除轴承横向振动。

With regard to the concrete example of the lateral oscilation of the bearings used in the No. 1 steam turbine electricity generator in Zhongzhou Branch, this paper analyzes the affection caused by rigidity of bearing on the oscilation of the machine set, introduces the ways to highten the rigidity of the bearing from the prospect of assembling in order to eliminate the lateral oscilation.
