Understanding some important terminologies
Before we learn more about gears and perform this chapter's activities, let's learn about some important terminologies:
- Drive gear: A gear that is connected to the motor.
- Driven gear: A gear that is connected to the drive gear.
- Mesh: This is when the drive and driven gears are connected to each other.
- Gear ratio: The ratio of number of teeth of driving gear / number of teeth of driven gear.
- Torque: The amount of force needed to bring your wheel into motion.
- Gear up: When your gear ratio is greater than 1, this is known as the gear up mechanism. With gear up, your driven gear moves at a faster speed than the drive gear and offers less torque.
- Gear down: When your gear ratio is less than 1, this is known as the gear down mechanism. With gear down, your driven gear moves at a slower speed than the drive gear and offers more torque.
Basically, whenever you need more power – for example, to...
