    • PROBLEM TO BE SOLVED: To enhance the welding strength of drum shafts and tool flanges of a rotatable working drum installed in a bucket of a bucket loader or an excavator. SOLUTION: The working drum (3) includes the drum shafts (9, 10) and the tool flanges (11) around them. The tool flanges (11) include end collars or end extended parts (12a). The end collars or the end extended parts (12a) are extended around the drum shafts (9, 10) and spread to leave gaps (S) for welding joints between the end collars or end extended parts (12a) while the tool flanges (11) keep desired spaces from each other along the axial direction of the drum shafts. Two tool flanges (11) and drum shafts (9, 10) are connected to each other by one welding joint existing in the gap (S). COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:提高安装在铲斗装载机或挖掘机的铲斗中的可旋转工作鼓的鼓轴和工具凸缘的焊接强度。 解决方案:工作鼓(3)包括鼓轴(9,10)和工具凸缘(11)。 工具凸缘(11)包括端部套环或端部延伸部分(12a)。 端部套环或端部延伸部分(12a)围绕鼓轴(9,10)延伸并扩展以留下用于在端部套环或端部延伸部分(12a)之间焊接接头的间隙(S),同时工具凸缘(11) )沿着鼓轴的轴向彼此保持期望的空间。 两个工具凸缘(11)和鼓轴(9,10)通过存在于间隙(S)中的一个焊接接头彼此连接。 版权所有(C)2011,JPO&INPIT
