This tool helps you determine the interference fit between a hole and a shaft. The interference fit is crucial for ensuring proper assembly and tightness in mechanical components.
Press Fit Interference Calculator
Enter the diameters of the hole and shaft to calculate the interference.
Interference:
0
How It Works:
- Input Diameters:
- Enter the diameter of the hole.
- Enter the diameter of the shaft.
- Calculate Interference:
- The calculator computes the interference, which is the difference between the hole diameter and the shaft diameter.
Formula: Δ=Dhole−Dshaft\Delta = D_{\text{hole}} – D_{\text{lancia}}Δ=Dhole−Dshaft
- Δ (Interference): The amount by which the shaft is larger than the hole, resulting in a press fit.
- D_{\text{hole}}: Diameter of the hole.
- D_{\text{lancia}}: Diameter of the shaft.
Example Calculation:
If the diameter of the hole is 50 mm and the diameter of the shaft is 49 mm, the interference is: Δ=50−49=1 mm\Delta = 50 – 49 = 1 \text{ mm}Δ=50−49=1 mm
This means the shaft will have a 1 mm interference fit with the hole, ensuring a snug fit.
