Question: A gear reduction unit uses the countershaft shown in the figure. Gear A receives power from another gear with the transmitted force FA applied
A gear reduction unit uses the countershaft shown in the figure. Gear A receives power from another gear with the transmitted force FA applied at the 20 pressure angle as shown. The power is transmitted through the shaft and delivered through gear B through a transmitted force FB at the pressure angle shown. For the steel countershaft shown below, assume the bearings have a maximum slope specification of 0.062 for good bearing life. Check wether the shaft dia below meets the requirement. If not determine a suitable shaft diameter. FA 11 KN- 20 400 mm Gear A, 600-mm dia. 350 mm 25 300 mm 50-mm dia. Gear B, 300-mm dia. The minimum shaft diameter is determined to be mm.
