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...

A compound reverted gear train will be used to decrease speed with a ratio of 36 to 1. In the figure below, the input shaft drives gear 5, and the output shaft is driven by gear 2. Use spur gears with a 20 degree pressure angle and a diametral pitch of 5 teeth / in. a) Specify the appropriate numbers of teeth for both gear sets to minimize the gearbox size, while also avoiding gear tooth interference....

Design Problem Design a speed reducer gear box that will take 1.5 kW power from an electric motor rotating at 3000 rpm (clockwise) and deliver it to a machine which operates at 2 different speeds, 1000 rpm (clockwise) and 500 rpm (counter-clockwise). Use Spur Gears with 20° pressure angle and 5mm module. Gear box should be of smallest possible size. The gear shift mechanism is not the part of the design A 2-speed double-reduction speed reducer is shown in the...

You work for a gearbox company and have been charged with helping to design a geared countershaft for a speed reducing gearbox. The gearbox consists of a compound reverted gear train as shown below and is to be designed for an exact 16:1 speed reduction ratio. The input motor provides 10-horsepower which is carried through the gear train and operates at a speed of 2,000 rpm. You are asked to consider spur gears with a 20° pressure angle and 4...

Problem 1. Design a reverted gear train for a transmission with three speeds and reverse. For an input speed of 450 rpm to the driving shaft (green), the driven shaft (teal) should have output forward speeds of 75, 300, and 450 rpm, and an output reverse speed of 150 rpm. Assume all gears have a diametral pitch of 10. Gear A (24 teeth) and Gear D (36 teeth) are in constant mesh. Determine the numbers of teeth for ALL six...
