Gears are mechanical components that transmit motion and force between rotating shafts. They consist of toothed wheels that interlock to change the direction, speed, or torque of motion.

A gear train is a system of gears working together. It can increase or decrease speed and torque based on the gear sizes and arrangements. Here are some key concepts:

Types of Gears:
1. **Spur Gears**: Straight teeth; ideal for parallel shafts.
2. **Helical Gears**: Angled teeth; smoother operation and can handle more load.
3. **Bevel Gears**: Conical shape; used to change the direction of rotation.
4. **Worm Gears**: A gear set that consists of a worm (screw) and a worm wheel; provides high torque and speed reduction.
5. **Planetary Gears**: A central sun gear, planet gears, and a ring gear; compact and efficient for high torque.

Gear Ratios:
The gear ratio is determined by the number of teeth on the gears involved. It influences the output speed and torque. For instance, a gear ratio of 2:1 means the output gear will turn once for every two turns of the input gear, effectively doubling the torque at the output but halving the speed.

Applications:
Gears and gear trains are used in various applications, including:
Automobiles (transmissions)
Industrial machines
Robotics
Clocks and watches
