The invention provides a vertical-type five-shaft linkage gear hobbing machine tool which comprises a machine frame. A hobbing head is arranged on the machine frame through a stand column. A hobbing cutter is arranged on the hobbing head. A first servo motor is connected with the hobbing cutter. A second servo motor is connected with the stand column. A working table is arranged on the machine frame through a bracket. A third servo motor used for driving a gear blank of a workpiece to be machined to rotate around an axis of the gear blank is arranged on the working table. A fourth servo motor is connected with the working table. A fifth servo motor is connected with the bracket. The axis of the gear blank of the workpiece to be machined is perpendicular to the horizontal plane of the working table. According to the vertical-type five-shaft linkage gear hobbing machine tool, the defects in the prior art are overcome, a non-circular gear can be efficiently machined in a high-precision mode, and the vertical-type five-shaft linkage gear hobbing machine tool is applicable to machining of the medium-size or small-size non-circular gear or skewed-tooth non-circular gear hobbing.
