4. Kinematic Analysis (Visualization)

Matlab was used to illustrate the position analysis of the gear box. The plot below shows the output angle for each speed setting versus the input angle. One complete revolution (360 degrees) of the input angle are visualized. The slope of the lines on this plot correspond to the gear ratios presented in the table on the previous page. As previously mentioned, the inverse of this ratio will be the multiplier for the torque output. 

Matlab was also used to visualize the gear sets used in each speed setting. From left to right, the visualization order is input shaft, intermediate shaft, and output shaft. The first gear set (from input to intermediate shaft) is colored black. The second gear set (from intermediate to output shaft) is colored blue. A radial line on the input and output gears illustrate the gear ratios involved. For example, in the first speed setting, the output gear only travels 0.5 times as much as the input gear. In the fourth speed setting, the output gear travels 1.4 times as much as the input gear. 

Note: For some reason, some of the videos don't work when embedded into the page. Thus, they are available as downloadable files at the end.
