3.螺纹角（Thread Angle）：ACME螺纹的标准螺纹角度为29度。这是螺纹的斜率，定义了螺纹的形状。4.顶径（Major Diameter）：螺纹顶部的直径，通常用英寸表示。5.底径（Minor Diameter）：螺纹底部的直径，通常用英寸表示。6.螺纹牙数（Number of Threads per Inch）：每英寸的螺纹牙数是螺纹的密度，也称为线数。
-螺纹角度(Thread Angle):29° -螺纹高度(Thread Height):等于1/8倍螺距 -螺距(Pitch):同一个直径上相邻两个螺纹峰之间的轴向距离 -螺纹内径(Minor Diameter):即螺纹深度的最小内径 -螺纹外径(Major Diameter):即螺纹深度的最大外径 此外,Acme梯形螺纹还有一些其他的尺寸参数,如螺纹起始位置、螺纹顶部圆角半径等...
R2 0.15 0.25 0.5 1 Formula for tap drill (round to closest available drill size): D1+(0.05*p) D1 = minimum internal thread minor diameter, p = pitch DIN 103 is similar to: JIS B 0217 Tolerance system for metric trapezoidal screw threads; ISO 2902/3/4; Chinese Standard GB/T5796Metric...
Stress Area of General Purpose Acme Threads: For computing the tensile strength of the thread section, the minimum stress area based on the mean of the minimum pitch diameter d2min. and the minimum minor diameter d1max. of the external thread is used. For computing the tensile strength of ...
The Stub ACME screw thread form can be applied to either Genrral or Centrializing ACME screw threads. The Major and Minor Diameter allowances for Stub Acme threads are the same as those given for General Purpose or Centrializing Acme screw threads. Pitch Diameter allowances for Stub Acme thr...
其中,Basic Minor Diameter是基本尺寸,Tolerance是公差范围。 3.3 牙高计算 ACME梯形螺纹的牙高可以通过以下公式进行计算: Thread Height = Pitch / 2 其中,Pitch是螺距。 4. ACME梯形螺纹的应用 ACME梯形螺纹由于其特定的基本尺寸标准,广泛应用于各种机械和工程领域。以下是一些常见的应用场景: •转动传动装置:ACME...
0.259 × (pitch dia. allowance on ext. thread) Frn = 0.4224P ? 0.259 × (major dia. allowance on internal thread) Frs = 0.4224P ? 0.259 × (minor dia. allowance on ext. thread ? pitch dia. allowance on ext. thread) Pitch Diameter Allowances and Tolerances: Allowances on the pitch ...
