Question

Check the deflection at gears and the slopes at the bearings.
If any of the deflections exceeds the recommended limits, make appropriate
changes to bring them all with in the limits given in the Table 7-2.
Given the below information: Problem Statement: A 16-Tooth pinion drives the double-reduction gear train shown in the figure. All gears have 20 pressure angles. The pinion rotates ccw at a speed of 1500 rpm and transmits power to the gear train. The motor provides a torque of 4000 lbf-in to the pinion shaft a. Design the shaft b (see figure) of the gear train. The minimum factor of safety for yielding is 3 and fatigue design factor of safety for an estimated life of 900,000 cycles is 2.5. N2 = 16, number of tooth on gear 2; N3 = 40, number of tooth on gear 3; Pn = 8, normal diametral pitch, gears 2 & 3; Helix Angle = 30 degrees for gears 2 & 3; N4 = 18, number of tooth on gear 4; N5 = 54, number of tooth on gear 5; Pn = 5, normal diametral pitch, gears 4 & 5; Helix Angle = 15 degrees for gears 4 & 5; Normal pressure angle for all gears, 20 deg.
