Problem 2: A photo of a gearbox and its schematic are shown in the figure. The gearbox consists of four spur gears. Gear1 and Gear3 have 100 teeth (N;=N3=100) and Gear2 and Gear4 have 150 teeth (N2=No=150). As indicated on the schematic, Gear1 is connected to the input shaft. Gear 2 and gear 3 are fixed on a same rotating axis/shaft so they will rotate together at the same rotational speed at all times (.e. n2=na). Gear4 is on the...

output input 2. The gearbox in the diagram for problem 1 receives an input power of 10 kW, at a speed of 40. The gears are spur gears (ignore the helix angle on the teeth in the figure), have a module of 5 mm/tooth, and the pressure angle is 20. Assume all shafts lie in the same plane. Assume the gearbox is reasonably efficient, so losses can be neglected for this analysis. (a) Determine the minimum inside dimension of the...

1. Gear kinematics. An input shaft drives Gear 1 with 20 teeth at 1800 rpm which mates with the 80-tooth Gear 2 which in on the intermediate shaft. Also on the intermediate shaft is Gear 3 with 18 teeth. It mates with Gear 4 on the output shaft, where Gear 4 has 90 teeth. a) How fast does Gear 2 spin, in rpm? b) Gears 2 and 3 spin at the same speed, so what is the speed of Gear...
