Gear Torque Formula:
| From: | To: |
Gear torque calculation determines the rotational force transmitted through gear systems. It's a fundamental calculation in mechanical engineering for designing and analyzing gear performance in various applications.
The calculator uses the gear torque formula:
Where:
Explanation: The torque produced by a gear is directly proportional to the tangential force applied at the pitch radius of the gear.
Details: Accurate torque calculation is essential for proper gear selection, ensuring mechanical systems operate within safe limits, and preventing gear failure due to excessive loading.
Tips: Enter tangential force in Newtons and pitch radius in meters. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is tangential force in gear systems?
A: Tangential force is the component of force that acts perpendicular to the radius at the point of contact, causing rotational motion in gear systems.
Q2: How is pitch radius different from other gear radii?
A: Pitch radius is the theoretical radius where gear teeth effectively mesh and transmit motion, different from outer radius or root radius.
Q3: Can this formula be used for all types of gears?
A: This basic torque formula applies to spur gears, helical gears, and bevel gears, though additional factors may need consideration for complex gear systems.
Q4: What are typical torque values for different gear applications?
A: Torque values vary widely from small precision instruments (fractional Newton-meters) to industrial machinery (thousands of Newton-meters).
Q5: How does gear ratio affect torque transmission?
A: Gear systems can multiply or reduce torque based on the gear ratio, with torque increasing as speed decreases in reduction systems.
