sector gear bearing[机] 扇形齿轮轴承;扇形齿轮轴承
gear sector齿轮齿条
So we need efficient and accurate sector gear shaping machine. Because of the shape of sector gear in the steering gear has the characters of variable rate and variable tooth thickness.
由于转向器用扇形齿轮齿形具有变速比变鼓的特殊性,普通机床的传动机构不能实现变速比齿扇的加工,通常只能用专用数控机床加工。
