A = /W 4 64 148 55.5 WORKING EQUATION 5 . 36 276 48 6. 16 12 144 W = 7 7. A driver gear has 36 teeth and makes 85.0 rpm. Find the rpm of the driven gear with SUBSTITUTION 72 teeth. 8. A motor turning at 1250 rpm is fitted with a gear having 54 teeth. Find the speed of w = 12 cm = 3.0 cm the driven gear if it has 45 teeth. 9. A gear running at 250 rpm meshes with another revolving at 100 rpm. If the smaller gear has 30 teeth, how many teeth does the larger gear have? ableal die rado 10 . A driver gear with 40 teeth makes 154 rpm. How many teeth must the driven gear have if it makes 220 rpm? 1 1. Two gears have a speed ratio of 4.2 to 1. If the smaller gear has 15 teeth, how many teeth does the larger gear have? 12. What size gear should be meshed with a 15-tooth pinion to achieve a speed reduction Fin of 10 to 3? 29 13. A driver gear has 72 teeth and makes 162 rpm. Find the rpm of the driven gear with 81 teeth. 14. A driver gear with 60 teeth makes 1600 rpm. How many teeth must the driven gear have if it makes 480 rpm? 15. What size gear should be meshed with a 20-tooth pinion to achieve a speed reduction of 3 to 1? 16. A motor turning at 1500 rpm is fitted with a gear having 60 teeth. Find the speed of the driven gear if it has 40 teeth. 17. The larger of two gears in a clock has 36 teeth and turns at a rate of 0.50 rpm. How many teeth does the smaller gear have if it rotates at 1/30 rev/s? 18. How many revolutions does an 88-tooth gear make in 10.0 min when it is meshed with a 22-tooth pinion rotating at 44 rpm? 19 If gear A turns in a clockwise motion, determine the motion of gear B in each gear train.
