10. The figure below illustrates the gears in a speed-change gearbox used in machine tool applications. By sliding the cluster gears on shafts B and C, nine speed changes can be obtained. The problem of the machine tool designer is to select tooth numbers for the various gears so as to produce a reasonable distribution of speeds for the output shaft. The smallest and largest gears are gears 2 and 9, respectively. Using 20 teeth and 45teeth for these gears, determine a set of suitable tooth numbers for the remaining gears. What are the corresponding speeds of the output shaft? 450 rev/min Input 7 8

1. To avoid the problem of interference in a pair of spur gears using a 20° pressure angle, specify the minimum number of teeth allowed on the pinion (Np.act) for each of the following gear ratios, and the corresponding maximum number of teeth on meshing gear (NG,act). Assume full depth tooth. a. 1.25 to 1 b. 1.6 to 1 c. 2.5 to 1 d. 3.2 to 1 2. Repeat problem 1 for helical gears with normal pressure angle of 20° and helix angle of 30°.
A set of gears is cut with a 4'2-in/tooth circular pitch and a 17/½° pressure angle.* The pinion has 20 full-depth teeth. If the gear has 240 teeth, what maximum addendum may it have to avoid interference?
only hand written otherwise i'll downvote
In the planetary gear train shown in below figure, Gear A is the driver and gears B and D are compounded.Gears E and C are internal gears with C as the fixed gear.Number of teeth on gears are TA-20;TB-60; Tc-140;TD-40;,TG-120. If the drive gears rotates at 720rpm CCW when seen from the right, find out the speed at which driven gear rotates C140 120 Output D 40 60 20 Input
Two mating 12-pitch gears have 18 external and 48 internal teeth, respectively. Determine the following: Their pitch diameters. • The center distance.
