Shaft Tolerance Calculator
Introduction
Calculating shaft tolerances is crucial in engineering and manufacturing to ensure precise fits between mating components. With the help of this calculator, you can easily determine the appropriate tolerances for shafts, ensuring optimal performance and functionality.
How to Use
Simply input the desired parameters into the designated fields and click the “Calculate” button to obtain the calculated tolerance value.
Formula
The formula used for calculating shaft tolerances is as follows:
Tolerance=Basic Size+(IT Grade×Tolerance Grade)
Where:
- Basic Size: The nominal size of the shaft.
- IT Grade: The international tolerance grade.
- Tolerance Grade: The specific tolerance grade required.
Example Solve
Let’s consider an example:
- Basic Size: 25 mm
- IT Grade: 6
- Tolerance Grade: h7
Substituting these values into the formula, we get:
Tolerance=25+(6×0.014)=25+0.084=25.084 mm
Thus, the calculated tolerance for this example is 25.084 mm.
