I have a number of questions about diesel-electric locomotive gearing: <br /> <br />1.) When a locomotive has a gear ratio given, what do the numbers represent? I'm guessing that they are the teeth count for the gear, but am usually wrong about such things. Also, is the first number for the gear mounted to the cranksahft, and the second for the gear on the alternator shaft, or is it the other way around? <br /> <br />2.) What is considered a "high" gear ratio, and what is considered a "low" one? <br /> <br />3.) What shape are the teeth on the gear (i.e. are they parallel to the axis, diagonal, v-shaped, etc.)? <br /> <br />4.) Is the correct term for the electricity-generating-device, alternator, generator, or dynamo? And for the internal combustion engine, is the correct term, engine or prime mover? <br /> <br />5.) In diesel-mechanical and diesel-hydraulic transmissions, what are common gear ratios? <br /> <br />I'm sorry to ask these rather basic questions, but I don't know much about this. <br /> <br />Any help you could provide would be most greatly appreciated, and I thank you very much for it. <br /> <br />Most sincerely yours, <br />Daniel Parks
