| 齿轮 gear 能互相啮合的有齿的机械零件。公元前300多年，希腊的亚里士多德在《机械问题》中阐述了用青铜或铸铁齿轮传递旋转运动的问题。公元235年，中国的马钧在其创造的指南车里应用了整套的轮系。1674年，丹麦的O.罗默提出用外摆线作齿廓曲线。1765年，瑞士的L.欧拉建议采用渐开线作齿廓曲线。1899年，O.拉舍最先实施了变位齿轮的方案。1923年美国的E.怀尔德哈伯提出圆弧齿廓的齿轮，1955年苏联的M.A.诺维科夫对圆弧齿轮进行了深入的研究并使其应用于生产。
用于齿轮的术语主要有：①轮齿(齿)。齿轮上每个用于啮合的凸起部分，其总数称为齿数。②齿槽(齿间)。相邻两齿之间的空间。③齿顶圆。过所有齿顶端的圆。④齿根圆。过所有齿槽底边的圆。⑤分度圆。计算齿轮几何尺寸的基准圆。⑥齿面。轮齿上位于齿顶圆柱面和齿根圆柱面间的侧表面。⑦齿廓。齿面被一指定曲面所截的截线。⑧齿厚。端面上一个齿的两侧齿廓间的分度圆弧长。⑨齿距(周节)。相邻两齿上相当点间的分度圆弧长。⑩模数。齿距与圆周率之比，以毫米计。径节。模数的倒数，以英寸计。齿顶高。齿顶圆与分度圆间的径向距离。齿根高。分度圆与齿根圆间的径向距离。全齿高。齿顶圆与齿根圆间的径向距离。齿宽。轮齿沿轴向的尺寸。端面压力角。齿廓与分度圆交点的径向线与该点的齿廓切线所夹的锐角。齿线。齿面与分度圆柱面的交线。齿轮的材料和热处理对其承载能力和尺寸、重量等有很大的影响，20世纪70年代后多用表面硬化钢。齿轮应用广泛，种类很多。按齿廓曲线可分为渐开线齿轮、摆线齿轮、圆弧齿轮等。按外形可分为圆柱齿轮、锥齿轮、非圆齿轮、齿条、蜗杆-蜗轮等；按轮齿所在的表面可分为外齿轮和内齿轮；按齿线形状可分为直齿轮、斜齿轮、人字齿轮、曲线齿轮等。按制造方法可分为铸造齿轮、切制齿轮、轧制齿轮、烧结齿轮等。
