RE: DLE222 Starter System - The Project
From above posting, i attached the graphical view of a 3 stage step down gears.
In the 3D diagram, each stage is colored differently. Please note if we stack the gear like in the picture, we can't have the same size gears all the way. The reason for this is, if the driven gears are of the same size, then it'll interfere with next stage pinion. And that is the main reason why in previous posting i mentioned that the final ratio depends on how we arrange those gear sizing.
In this example, the 'green stage' is having a ratio of 2.88. The yellow stage is 3.33 and the white stage is 3.33 also. Therefore the whole step down ratio is 2.88 x 3.33 x 3.33 = 31.9. Close but slightly below of what we wanted. Need to work on it further.
