In order to guarantee the spindle and the suitable front bearing gap, the front bearing has the outer cone and the aperture. Adjusting on the bearing two nuts, it causes bearing movement along the front axle when motion and causes contraction of the front bearing hole then to be possible to eliminate the gap between the main axle and the bearing. The topic main content of topic is hob-cutter frame design as well as the spindle assembly design:8mm maximum machining modulus of the basic parameters,hobbing tool holder to design,develop the overall program,structural design,the main parts of the design calculation and strength check.Make the design of the turret and the table can be used for gear cutting,finally with CAD software to generate drawings.Key words :gear hobbing machine,cutter frame, gear
