Gear Module Formula:
| From: | To: |
The gear module is a fundamental parameter in gear design that represents the size of the gear teeth. It is defined as the ratio of the pitch diameter to the number of teeth. The module is typically measured in millimeters and is a critical factor in determining gear strength and compatibility.
The calculator uses the gear module formula:
Where:
Explanation: The module indicates the size of the gear teeth, with larger modules representing larger, stronger teeth suitable for transmitting higher torque.
Details: Accurate module calculation is essential for proper gear design, ensuring correct meshing between gears, appropriate strength for the application, and optimal power transmission efficiency.
Tips: Enter the pitch diameter in millimeters and the number of teeth. Both values must be positive numbers (pitch diameter > 0, number of teeth ≥ 1).
Q1: What is the typical range of gear modules?
A: Gear modules typically range from 0.5 mm for small precision instruments to 25 mm or more for heavy industrial applications.
Q2: How does module relate to gear strength?
A: Larger modules generally mean larger, stronger teeth that can handle higher loads, but they also result in larger overall gear size.
Q3: Are standard module sizes available?
A: Yes, gear modules are typically standardized according to ISO standards to ensure compatibility between different manufacturers.
Q4: How does module affect gear noise?
A: Generally, gears with smaller modules run more quietly but have lower load capacity compared to gears with larger modules.
Q5: Can this calculator be used for materials other than steel?
A: While the formula is material-independent, the results are most applicable to steel gears which are the most common in industrial applications.
