1. What is Garter Spring Radial Force?

Definition: This calculation determines the radial force exerted by a garter spring based on its diameter, spring constant, and deflection.

Purpose: It helps engineers and designers properly size garter springs for sealing applications and other mechanical systems.

2. How Does the Calculation Work?

The calculation uses the formula:

Where:

• \( P \) — Radial force (Newtons)
• \( D \) — Spring diameter (meters)
• \( K \) — Spring constant (N/m)
• \( \delta \) — Radial deflection (meters)

Explanation: The formula calculates the force generated when a garter spring is radially deflected from its free diameter.

3. Importance of Garter Spring Force Calculation

Details: Proper force calculation ensures effective sealing performance, proper spring selection, and prevents premature failure.

4. Using the Calculator

Tips: Enter the spring diameter in meters, spring constant in N/m, and deflection in meters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical spring constant for garter springs?
A: Spring constants typically range from 100-1000 N/m depending on wire diameter and coil count.

Q2: How do I measure spring diameter?
A: Measure the inside diameter of the spring in its free (uncompressed) state.

Q3: What affects the spring constant?
A: Wire diameter, material, coil pitch, and number of active coils all affect the spring constant.

Q4: What's a typical deflection range?
A: Garter springs are typically deflected 10-30% of their free diameter in sealing applications.

Q5: Does temperature affect the calculation?
A: Yes, temperature can affect material properties and thus spring performance.
