What are Gears?
Gears are mechanical elements designed to transmit turning movements.
Characteristics of Gears
Two main characteristics define a gear:
- Number of Teeth (Z): This characteristic represents the number of teeth on a gear.
- Rotational Speed (N): This characteristic represents how fast a gear rotates.
Gear Ratios and Speed Control
Different Number of Teeth
Using gears with different numbers of teeth allows us to modify a machine's rotational speed. If the output gear is larger than the motor gear, it will rotate slower. Conversely, if the output gear is smaller, it will rotate faster.
Same Number of Teeth
If two gears have the same number of teeth, they will rotate at the same speed.
Motor Gear vs. Output Gear
In a gear pair:
- The motor gear initiates
