## 公差配合计算 Description
公差配合计算应用程序根据输入直径值计算“孔”和“轴”的拟合公差。拟合公差基于ISO计算。
只需输入直径值，使用公差区域按钮选择公差区域，使用公差等级按钮选择公差等级，将显示“孔”和“轴”的拟合公差值。
此外，从所选孔和轴的组合，我们区分了配合类型（余隙配合，过渡配合，过盈配合）。然后，计算最小间隙和最大间隙，在间隙的情况下，它写为“加”，如果是干涉，则写为“减”。
输入直径可达3150 mm或更小。但是，输入数字的数量限制为6位数。
相应的公差范围和公差等级如下。

【孔公差】
A，B，C，CD，D，E，EF，F，FG，G，H，JS，J，K，M， ZA，ZB，ZC

*注1）A和B孔不适用于1 mm或更小的标准尺寸。
*注2）JS 7~JS 11截断小数部分，使IT / 2成为以微米为单位的整数。
*注3）J孔的公差等级仅为IT6至IT8。

【轴公差】
a，b，c，cd，d，e，ef，f，fg，g，h，js，j，k，m，n，p，r，s，t，u，v，x， za，zb，zc

*注4）a和b轴不适用于标准尺寸1 mm或更小。
*注5）js 7~js 11向下舍入到小数点，以便IT / 2成为微米单位的整数。
*注6）j轴的公差等级仅为IT5至IT8。

【公差等级】
IT 1到IT 18

*注7）公差等级IT14至IT18不适用于1 mm或更小的标准尺寸。
*注8）对于大于500 mm的标准尺寸，公差等级IT1至IT5的公差值是临时用于实验用途。

## 公差配合计算 Reviews in China

### ***** "最适用"
这软件太好用了，机加工人必备工具。
-- 樊谜, 2024-04-01

### *---- "没用的玩意"
真没用，还骗人6元钱
-- 有意思yys, 2021-04-29

### *---- "骗钱的"
骗钱的。孔轴都只能输入一个数值
-- QHBSIWN, 2020-11-12

### *---- "和查表没区别"
什么玩意，什么功能都没有，和查表有什么区别，就这你就敢收钱？真是骗子越来越多了。要购买的同学们注意，界面只能够选填基本尺寸，然后下面有孔和轴的配合自己选，觉得比查表方便的可以下载。
