Examine the gear drive system shown below. All the gears have a DP = 12. The smallest gear is the primary driver gear and has 15 Teeth, RPM = 3600, and Torque = 2.2 N-m. That small gear meshes with a 72-tooth gear which is connected to another gear that has 20 teeth. That 20-tooth gear connects to the final driven gear that has 64 teeth. What is the final output RPM of the 64-tooth gear? What is the final output Torque supplied by the 64 tooth gear?
Figure shown below illustrates the gears in a speed-change gearbox used in machine tool applications. By sliding the cluster gears on shafts Band C, nine speed changes can be obtained as shown in Table given below. The problem of the machine tool designer is to select tooth numbers for the various gears (2 to 10) so as to produce a reasonable distribution of speeds for the output shaft. The gears 2, 6 and 9 are having 20, 25 and 50 teeth respectively. The input shaft speed is 450 rpm and the output speed can vary from 137 rpm to 580 rpm depending on the sequence of the gears. If the output speed obtained through the gear sequence 2-5-5-8 is 257 rpm and if the minimum and maximum number of teeth in the gear system are 20 and 50 respectively, (i) Suitable tooth numbers for the remaining gears (3,4,5,7,8 & 10)
