Further, the calculation for the overall gear ratio was explained, which is simply the speed of the first gear over that of the last gear. The class also learned how to use a speed reducer catalog and compare thermal ratings of those reducers. Real World Applications: The application that comes to mind most immediately for gear trains is the transmission in a car. The set of gears in the transmission allows for the engine to produce the same amount of power but shift gears to generate higher speeds in the wheels. Gear trains can also be used in many other applications, such as for conveyors in a factory or even small wind-up toys. Lab 1. Calculation of gear ratios using Job Master Trainer.
