1. What is Nominal Packing Cross-section?

The Nominal Packing Cross-section of Bush Seal is a surface or shape exposed by making a straight cut through something, especially at right angles to an axis. It represents the theoretical cross-sectional area of the bush seal packing in a conical spring assembly.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( w \) — Nominal Packing Cross-section of Bush Seal (m)
• \( Da \) — Actual mean diameter of spring (m)
• \( Do \) — Outer diameter of spring wire (m)
• \( dsw \) — Diameter of spring wire (m)

Explanation: This formula calculates the nominal packing cross-section based on the geometric properties of the conical spring and its wire components.

3. Importance of Calculation

Details: Accurate calculation of nominal packing cross-section is crucial for proper seal design, ensuring effective sealing performance, and preventing leakage in mechanical systems using conical springs.

4. Using the Calculator

Tips: Enter all dimensions in meters. Ensure all values are positive and measured accurately for precise results.
