For this project, you are required to design three transmission shafts to perform the specified task as stated below. 1. A 2 kN load due to mud should be lifted 80 meters within 90 seconds. 2. Power is input through the motor attached to shaft SI. 3. The extra power spins a 1.5 kW generator by shaft S3. 4. The tension ration for pulley III is 8:1. Also, assume angle of wrap of the belts on the pulleys is 180°. 350 350 300 200 750 Ge 250 E Sketch b, for Project 19.2 Figure 1: Deep water well mud extractor IV W=2000 N NG NG NG NG 20° 32 32 80 64 da da das dG dpy 100 mm 100 mm 250 mm 200 mm 500 mm Table 1: Gear properties The properties and dimensions of the gears are given in table 1. dp 400 mm The supports (A-F) are bearings that allow rotation, but prevent translation in the transverse directions. The pitch angle is represented by o. Since gears have not yet been discussed in class, some useful formulas used for determining forces caused by gears are given below. When two gears mesh with each other, the ratio of rotational speeds (n) is related to the number of teeth (N) in the gear and the diameter of the gear (d). For gears 1 and 2, the speeds and sizes are related as follows: N₁ n2 di d2 == F, N2 = T Ft = F₁ sino Fi d F₁ cos
