A gearbox is required to transmit 3.5 kWh from a shaft rotating at 200 rpm. The desired output speed is approximately 90 rpm. The input shaft is on the horizontal axis and the output shaft is on the vertical axis. Draw gear arrangement and select suitable gears for it. May draw multiple different arrangements and explain why.
Homework Answers
Gear combination for 90 RPM output is given above.
| Teeth | RPM |
| 30 | 200 |
| 48 | 125 |
| 36 | 125 |
| 50 | 90 |
Hope this helps.

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...

Design requirements: You are required to design a gear box to reduce 2,000 rpm to 90-100 rpm while transmitting a power of 18 hp. The gearbox size should be less than 15 in x 15 in base, and 20 in height and input and output shaft must be in-line. The shaft must have an infinite life, while gear and bearing life should be greater than 10,000 hours. The bearings must have a reliability of 96%....

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...

Question#1140Marksl The shaft shown in the figure is rotating at 650 rpm and it receives 5592.75 W through a flexible coupling at its right end. The power is delivered to an adjacent shaft through a single helical gear B having a normal pressure angle of 20° and a helix angle of 15o. The pitch diameter for the gear is 105.1814 mm (4.141 in). A spacer is used to position the gear relative to bearing C. The...
