Zusammenfassung:	The present invention discloses a gear and a method for forming a tooth profile thereof. In the method of the present invention, a cubic curve is used to modify a basic tooth shape of a standard rack to obtain an amended basic tooth shape, wherein the cubic curve contacts tangentially with the basic tooth shape at the midpoint of a dedendum, a midpoint of a lateral and a midpoint of an addendum of the basic tooth shape. The amended basic tooth shape is reproduced to obtain an amended rack, and the amended rack is further used to generate a tooth profile of a desired gear.
