我厂在加工2.5万千瓦汽轮机转子主轴(外形尺寸:φ420×4759,重3300公斤)时,因无大型落地镗床,设计、制造了随动支架,用它配合T 611 A镗床,顺利地完成了转子主轴键槽的加工(见图1),加工质量达到了图纸技术要求。随动支架的结构:随动支架上部是一个带夹箍的元宝铁,由销钉螺丝连接在活动支承轴上。支承轴上套有一个选定参数的压缩弹簧,弹簧放在支承轴与可调套筒螺母之间,套筒螺
When processing the main shaft of steam turbine rotor of 25MW (external dimension: φ420 × 4759, weighing 3300 kg), our factory designs and manufactures a follower support without a large floor boring machine. With it, it completes T 611 A boring machine smoothly Rotor spindle spline processing (see Figure 1), processing quality to meet the technical requirements drawings. Followed by the structure of the stent: Followed by the upper bracket is a band iron with a clip, the pin screw connected to the movable support shaft. The supporting shaft is sleeved with a compression spring of selected parameters, the spring is placed between the supporting shaft and the adjustable sleeve nut, the sleeve screw
