1. What is Torque and Gear Ratio?

Torque is a rotational force that causes an object to rotate about an axis. Gear ratio is the ratio of the number of rotations of a driver gear to the number of rotations of a driven gear. Together, they determine the output torque in mechanical systems.

2. How Does the Calculator Work?

The calculator uses the torque multiplication formula:

Where:

• Input Torque — The rotational force applied to the input shaft (N·m)
• Gear Ratio — The ratio of teeth between gears (unitless)
• Efficiency — The mechanical efficiency of the gear system (decimal between 0-1)

Explanation: The gear ratio multiplies the input torque, while the efficiency factor accounts for energy losses in the system.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for designing mechanical systems, selecting appropriate motors, and ensuring proper power transmission without overloading components.

4. Using the Calculator

Tips: Enter input torque in N·m, gear ratio (typically >1 for torque multiplication), and efficiency (0.95 is typical for well-lubricated gears). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical gear ratio range?
A: Common gear ratios range from 1:1 to 100:1 or more, depending on the application. Higher ratios provide more torque multiplication but lower output speed.

Q2: How does efficiency affect output torque?
A: Efficiency accounts for friction losses. A 0.95 efficiency means 5% of the input power is lost as heat and noise.

Q3: Can output torque be less than input torque?
A: Yes, if the gear ratio is less than 1 (speed increasing configuration) and efficiency losses are considered.

Q4: What units should I use for torque?
A: This calculator uses Newton-meters (N·m), but you can convert from other units before entering values.

Q5: Does this work for all gear types?
A: The principle applies to spur, helical, bevel, and worm gears, though efficiency varies significantly between types.
