Gears
Gears play a crucial role in mechanical systems by transmitting motion and power with specified speed and torque ratios. Various gear tooth profiles and parameters, along with laws governing gear interaction, define their functionality. Understanding types of gears, gear trains, force analysis, and computer-aided simulation is essential for designing efficient mechanical systems.

What we have learnt
- Gears are essential components that facilitate motion transfer and power transmission in machines.
- Different gear profiles and configurations impact performance and interaction, affecting speed and torque.
- Computer-aided simulation tools are vital for analyzing gear performance and optimizing design.
Key Concepts
- -- Gear Tooth Profiles
- Tool designs that determine how gears mesh, including involute and cycloidal profiles.
- -- Pitch Circle
- The imaginary circle that serves as the reference point for gear tooth interaction.
- -- Contact Ratio
- The average number of teeth in contact at any given time, crucial for smooth operation.
- -- Fundamental Law of Gearing
- This law states that the common normal at the contact point must pass through the pitch point.
