The invention discloses a medium-speed diesel engine crankshaft flexible mounting structure which comprises a hydraulic flexible supporting structure, the hydraulic flexible supporting structure is higher than a bearing bush, the hydraulic flexible supporting structure comprises nylon rollers and a hydraulic piston, the two nylon rollers are fixedly connected with the hydraulic piston, and the two nylon rollers are fixedly connected with the hydraulic piston. In a working state, the crankshaft falls on the hydraulic flexible supporting structure after being lifted, so that the impact of the crankshaft is controlled, and a bearing bush is not damaged. When the hydraulic mechanism relieves pressure, the crankshaft can fall slowly, and therefore zero impact on a bearing bush in the crankshaft installation process is achieved. According to the invention, the operation requirement on an operator in the installation process of the crankshaft of the medium-speed diesel engine is reduced to the greatest extent, and the impact on a bearing bush in the installation process of the crankshaft is also thoroughly avoided.

    本发明公开了一种中速柴油机曲轴柔性安装结构,包括液压柔性支承结构,所述液压柔性支承结构高过轴瓦设置,所述液压柔性支承结构包括尼龙滚轮和液压活塞,所述两个尼龙滚轮与液压活塞固定连接,工作状态下:当曲轴被吊起后先落在液压柔性支承结构上从而控制曲轴的冲击不损伤轴瓦。当液压机构泄压,曲轴就会缓慢下落,从而实现曲轴安装过程中对轴瓦的零冲击。本发明最大程度的降低了中速柴油机曲轴安装过程中对操作工的操作要求,也彻底的回避了曲轴安装过程中对轴瓦的冲击。
