CNC MACHINE OF SPIRAL BEVEL GEARS, AND MACHINING METHOD OF SPIRAL BEVEL GEARS BY CNC MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a CNC machine of a spiral bevel gears requiring no tilting mechanism for inclining a tool axis to a rotary axis of a swivel drum or turning of a machine root angle in machining.;SOLUTION: The tool axis T inclines at an unadjustable inclination (K) fixed to the reference axis O, and a tool spindle 38 continuously turns with the reference axis O as the center by a swivel drum 44. A work gear spindle 18 demarcates a reference surface by the axis and the reference axis O, and can adjust an angle position with the pivot axis P orthogonal to the reference surface as the center on machining individual bevel gears, and does not change the angle position in machining. The inclination K and the angle position are set so as to realize rolling motion between a work gear 22 and a tool 42.;COPYRIGHT: (C)2004,JPO&NCIPI
