我们在对德产Bleicbert15t履带吊车改造为625tm强夯设备过程中,行走部分遇到了原行走减速器的输入轴与新增减速装置输出轴的连接问题。原输入轴伸出减速箱壳体仅60mm,靠锥形单键联接,其结构如图1。开始设计的新增减速装置输出轴6采用了图1所示结构,轴6锥孔和原输入轴4的配合靠锥面对中,一旦加工成型,其轴向尺寸就成定值。如果锥孔尺寸小,则在壳体7与钢梁3之间就有间隙,为此须
During the process of rebuilding the Bleicbert 15t crawler crane from Germany to a 625-tm powerful boring machine, the walking part encountered the connection problem between the input shaft of the original traveling reducer and the output shaft of the new deceleration device. The original input shaft is only 60mm out of the gearbox housing and is connected by a conical single-key connection. Its structure is shown in Figure 1. The output shaft 6 of the new deceleration device that was originally designed adopts the structure shown in Fig. 1. The countershaft of the shaft 6 and the original input shaft 4 are faced with a cone. Once it is processed and formed, its axial dimension becomes a fixed value. If the tapered hole size is small, there will be a gap between the housing 7 and the steel girder 3, for which
