The invention provides a high-bearing crankshaft nitriding supporting lifting appliance device which comprises a frame, two of the frame are provided with lifting pieces used for lifting a crankshaft right opposite to upper frame cross arms, upper frames of the two cross arm lifting pieces are provided with limiting pieces used for limiting the lifting pieces, and a lifting space used for lifting the crankshaft is formed in the frame. According to the invention, the crankshaft and the main journal are mounted in the hoisting piece in a clearance manner, the hoisting piece is crossly supported on the frame, and the crankshaft is freely hoisted on the frame at the moment, so that the crankshaft can be vertically charged into a furnace through self weight for nitriding treatment, the deformation of parts in a high-temperature and long-time heat preservation environment due to gravity and external force is reduced, and very good social benefits and economic benefits are obtained.
本发明提供了一种高承载曲轴氮化支撑吊具装置,包括框架,所述框架的其中2个正对上边框横担有用于吊装曲轴的吊装件,2个横担吊装件的上边框设有对吊装件进行限定的限位件,所述框架内设有吊装曲轴用吊装空间。本发明中,曲轴主轴颈间隙安装在吊装件内,吊装件横担在框架上,此时曲轴自由吊装在框架上,使得曲轴通过自重就可垂直装炉进行氮化处理,减少零件因重力、外力在高温长时间保温的环境中的变形,取得了非常好的社会效益和经济效益。
