某船用汽轮发电机组齿轮箱输出转架拉毛故障分析研究
|
摘要
文章针对某船用汽轮发电机组行星减速器在拆检过程中发现的输出转架拉毛故障,对拉毛故障原因进行了分析,明确了故障原因为减速器箱体喷丸后未及时清理干净,在机组运行过程中,喷丸小钢珠随着润滑油进入减速器轴承,嵌入轴承油囊处的巴氏合金内,与输出转架摩擦导致输出转架和轴瓦表面拉毛。通过试验研究,提出了一种新的更换输出转架配打圆柱销的工艺方法。通过输出转架与发电机轴的销孔配打、发电机转子动平衡、发电机运行试验及对中处理,解决了输出转架拉毛的故障,并降低了该减速器再次出现输出转架故障时发电机转子报废的风险,为后续结构类似机组更换输出转架进行了有益的探索,为实际汽轮发电机组的使用提供了试验依据及数据支撑。
This paper analyzes the cause of the pulling failure of the output turret in the process of dismantling the planetary reducer of a marine turbo generator set. Through the experimental research,a new process method for replacing the output turret with the cylindrical pin is proposed,which solves the fault of the output turret pulling and reduces the risk of the generator rotor being scrapped when the reducer reappears in the output turret. It has made a useful exploration for the replacement of the output turret with similar units,and provided experimental basis and data support for the actual use of the steam turbine generator set.
