Spur Gears Figure 1: Gearbox with four spur gears, an input shaft, an intermediate shaft, and output shaft. Each shaft is simply supported by bearings at locations I-VI. In this example, the spur gears have mating teeth that will exert both tangential and radial forces due to the involute profile shape of the teeth (see Chapter 15, Figures 15.3 - 15.8). Assume a 30-degree pressure angle between the mating gears. The application for this gearbox requires 2 kW with a rotational speed of 2000 rpm as output from the output shaft. Tin represents an input torque applied by a motor to the input shaft. Assume all gears have a width of 12mm. 4. Determine the location and value of maximum total bending moment in each shaft. Hint: Moment is a vector and in part b) you have calculated the y- and z- components. The x-component was determined in part c). However, torque produces shaft torsion only; it does not contribute to the shaft bending and therefore does not vectorially contribute to the total bending moment.
