Tooth Profile

释义 Definition

tooth profile齿形;指齿轮(或齿条等)单个齿的轮廓形状与曲线(如渐开线齿形),决定啮合特性、传动平稳性、承载能力与噪声等。(在不同语境中也可泛指“牙的外形轮廓”,但工程领域最常用的是齿轮齿形。)

发音 Pronunciation (IPA)

/tuθ profal/

例句 Examples

The tooth profile affects how smoothly the gears run.
齿形会影响齿轮运转的平稳程度。

To reduce noise and improve load capacity, the engineer modified the tooth profile and checked the contact pattern under load.
为降低噪声并提高承载能力,工程师调整了齿形,并在载荷条件下检查了接触斑点(啮合接触情况)。

词源 Etymology

tooth 原义为“牙齿”,在机械中借用来表示齿轮的“齿”;profile 来自法语 profil,意为“侧面轮廓/外形”。合在一起,tooth profile 字面就是“齿的轮廓”,在齿轮学中专指齿轮齿廓曲线与形状。
