Gear Ratios

When a larger gear is connected to a motor and the smaller gear is driven the speed_______

• Speed increases

• Speed Decreases

• stays the same

• will not move

When you increase speed you _________ torque using this gear ratio.

• decrease

• increase

• stays the same

• will not move

When two gears are meshed together, they rotate in ____________ directions.

• opposite

• the same

• will not move

When the smaller gear is connected to a motor and the larger gear is driven the speed ___________

• increases

• decreases

• will not move

You may want to use increased torque to...

• drive faster

• pick something up

When two gears are meshed together that are the same size what is the gear ratio?

• 1:1

• 2:1

When two gears are meshed together that are the same size what is the gear ratio?

• 1:1

• 2:1

Sometimes a gear is used between two gears. This gear is called an __________ gear

• inbetween

• idler

True or False: It does not matter the size of the idler gear, just the sizes of the driving and driven gear when looking at gear rations for speed and torque.

• True

• False

What gear is attached to the motor?
