Name: Date: 7.1 Gear Ratios A gear ratio is used to figure out the number of turns each gear in a pair will make based on the number of teeth each gear has. To calculate the gear ratio for a pair of gears that are working together, you need to know the number of teeth on each gear. The formula below demonstrates how to calculate a gear ratio. Notice that knowing the number of teeth on each gear allows you to figure out how many turns each gear will take. Why would this be important in figuring out how to design a clock that has a minute and hour hand? A gear with 48 teeth is connected to a gear with 12 teeth. If the 48-tooth gear makes one complete turn, how many times will the 12-tooth gear turn? Turns of output gear? 48 input teeth = One turn for the input gear 12 output teeth 48 teeth × 1 turn Turns of output gear? = = 4 turns 12 teeth 1. A 36-tooth gear turns three times. It is connected to a 12-tooth gear. How many times does the 12-tooth gear turn? 2. A 12-tooth gear is turned two times. How many times will the 24-tooth gear to which it is connected turn? 3. A 60-tooth gear is connected to a 24-tooth gear. If the smaller gear turns ten times, how many turns does the larger gear make? 4. A 60-tooth gear is connected to a 72-tooth gear. If the smaller gear turns twelve times, how many turns does the larger gear make? 5. A 72-tooth gear is connected to a 12-tooth gear. If the large gear makes one complete turn, how many turns does the small gear make? 7.1
Page 2 of 2 6. Use the gear ratio formula to help you fill in the table below. Table 1: Using the gear ratio to calculate number of turns 7.1 Input Output Gear ratio How many turns does How many turns does Gear (# of teeth) Gear (# of teeth) (Input Gear: Output Gear) the output gear make if the input gear turns 3 times? the input gear make if the output gear turns 2 times? 24 24 36 12 24 36 48 36 24 48 7. The problems in this section involve three gears stacked on top of each other. Once you have filled in Table 2, answer the questions that follow. Use the gear ratio formula to help. Remember, knowing the gear ratios allows you to figure out the number of turns for a pair of gears. Table 2: Set up for three gears Setup Gears Number of teeth 1 Top gear 12 Middle gear 24 Bottom gear 36 2 Top gear 24 Middle gear 36 Bottom gear 12 3 Top gear 12 Middle gear 48 Bottom gear 24 4 Top gear 24 Middle gear 48 Bottom gear 36 Ratio (top gear: middle gear) Ratio 2 (middle gear: bottom gear) Total gear ratio (Ratio 1 x Ratio 2) 8. As you turn the top gear to the right, what direction does the middle gear turn? What direction will the bottom gear turn? 9. How many times will you need to turn the top gear (input) in setup 1 to get the bottom gear (output) to turn once? 10. If you turn the top gear (input) in setup 2 two times, how many times will the bottom gear (output) turn? 11. How many times will the middle gear (output) in setup 3 turn if you turn the top gear (input) two times? 12. How many times will you need to turn the top gear (input) in setup 4 to get the bottom gear (output) to turn 4 times?
