1. What is the Spur Gear Dimensions Calculation?

The spur gear dimensions calculation determines the key measurements of a spur gear based on module (mm/tooth) and number of teeth. This is essential for mechanical design and manufacturing of gear systems.

2. How Does the Calculator Work?

The calculator uses the fundamental gear equation:

Where:

• \( module \) — Module size in mm/tooth
• \( teeth \) — Number of teeth on the gear

Key Calculations:

• Pitch Diameter = module × teeth
• Outer Diameter = module × (teeth + 2)
• Root Diameter = module × (teeth - 2.5)
• Circular Pitch = π × module

3. Importance of Gear Dimension Calculation

Details: Accurate gear dimension calculation is crucial for proper meshing of gears, efficient power transmission, noise reduction, and longevity of mechanical systems.

4. Using the Calculator

Tips: Enter module in mm/tooth and number of teeth. Both values must be positive numbers (module > 0, teeth ≥ 1).

5. Frequently Asked Questions (FAQ)

Q1: What is module in gear terminology?
A: Module is a measure of tooth size, defined as the ratio of pitch diameter to number of teeth (mm/tooth).

Q2: What are typical module values?
A: Module values typically range from 0.5 mm to 10 mm, with common values between 1-4 mm for many applications.

Q3: How does module affect gear size?
A: Larger module means larger teeth and consequently larger gear diameter for the same number of teeth.

Q4: What is the difference between pitch diameter and outer diameter?
A: Pitch diameter is the theoretical diameter where gears mesh, while outer diameter is the actual outside measurement of the gear.

Q5: Can this calculator be used for SVG generation?
A: Yes, the calculated dimensions can be used to generate accurate SVG representations of spur gears for design purposes.
