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)

Straight bevel gears are mainly used to change the change the rotation axis of intersecting shafts. You work as a maintenance engineer for a food packaging company and your supervisor asked you to accurately calculate the dimensions for a set of straight bevel gears used in one of the differential gearboxes at the facility. The gear type is an uncrowned straight-bevel pinion has 22 teeth, a module of 4.5 mm, and a transmission accuracy number of 5. The pinion and the gear are made of through-hardened steel, both having core and case hardnesses of 210 Brinell. The pinion drives the 24-tooth bevel gear. The shaft angle is 90°, the pinion speed is 1600 rev/min, the face width is 23 mm, and the normal pressure angle is 20°. Both gears have an outboard mounting. Find: a) The power rating based on AGMA pitting resistance if the life goal is 10° revolutions of the pinion at 0.98 reliability.
