1. What is Diameter of Driving Shaft of Coupling?

Definition: This calculator determines the diameter of a driving shaft in a coupling based on the thickness of the output flange, including manufacturing tolerance considerations.

Purpose: It helps mechanical engineers and designers properly size coupling components for power transmission systems.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ d = 2 \times t_o \]

Where:

\( d \) — Diameter of driving shaft (meters)
\( t_o \) — Thickness of output flange (meters)

Explanation: The shaft diameter is simply twice the thickness of the output flange, with an optional tolerance percentage applied.

3. Importance of Shaft Diameter Calculation

Details: Proper shaft sizing ensures sufficient strength for torque transmission, proper fit with couplings, and system reliability.

4. Using the Calculator

Tips: Enter the flange thickness in meters and manufacturing tolerance percentage (default ±5%). All values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is the shaft diameter twice the flange thickness?
A: This ratio provides optimal strength and material usage for most coupling applications.

Q2: What's a typical manufacturing tolerance?
A: ±5% is common, but this may vary based on application requirements and manufacturing capabilities.

Q3: When would I change the tolerance value?
A: Adjust for precision applications (lower tolerance) or when using different manufacturing methods.

Q4: How do I measure flange thickness?
A: Use calipers or micrometers to measure the thickness at several points around the flange.

Q5: Does this calculation account for stress concentrations?
A: No, additional analysis may be needed for high-stress applications or dynamic loading conditions.
