1. What is Transmitted Torque by Keyed Shaft?

Transmitted Torque by Keyed Shaft is defined as the amount of torque or the rotating power transferred from a shaft using a key into it. This calculation is essential in mechanical engineering for designing and analyzing power transmission systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( M_t \) — Transmitted Torque by Keyed Shaft (N·m)
• \( F \) — Force on Key (N)
• \( d_s \) — Diameter of Shaft using Key (m)

Explanation: The formula calculates the torque transmitted through a keyed shaft assembly based on the force applied to the key and the shaft diameter.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for designing mechanical systems, ensuring proper power transmission, preventing component failure, and maintaining system reliability in various engineering applications.

4. Using the Calculator

Tips: Enter force on key in Newtons (N) and shaft diameter in meters (m). All values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of the key in torque transmission?
A: The key provides a positive drive connection between the shaft and the mounted component, preventing relative rotation and enabling efficient torque transmission.

Q2: How does shaft diameter affect torque transmission capacity?
A: Larger shaft diameters generally allow for higher torque transmission capacity as they provide greater surface area for key engagement and higher material strength.

Q3: What are typical applications of keyed shafts?
A: Keyed shafts are commonly used in gearboxes, pulleys, couplings, sprockets, and various rotating machinery where positive torque transmission is required.

Q4: Are there limitations to this calculation method?
A: This formula provides a basic calculation and doesn't account for factors like key material strength, stress concentrations, fatigue considerations, or safety factors that should be considered in actual design.

Q5: What units should be used for accurate results?
A: For consistent results, use Newtons (N) for force and meters (m) for diameter to get torque in Newton-meters (N·m). Ensure unit consistency throughout the calculation.
