tooth thickness:齿厚;指齿轮等带齿零件中,单个齿在规定参考圆(常为分度圆)处的厚度,通常沿圆弧方向测量,用于评估啮合间隙、加工精度与传动性能。(在不同测量方法下也可指弦齿厚等相关尺寸。)
/tuːθ ˈθɪknəs/
The technician measured the tooth thickness to check whether the gear was within tolerance.
技术员测量了齿厚,以检查齿轮是否在公差范围内。
If the tooth thickness is too large, the gears may bind, increasing noise and wear during operation.
如果齿厚过大,齿轮可能发生卡滞,从而在运行中增加噪声与磨损。
该短语由 tooth(“齿;牙;齿状突起”,在机械语境中常指齿轮的“齿”)与 thickness(“厚度”)组合而成,是工程与制造领域的常用复合名词,用来精确描述齿形几何参数。
