Can anyone tell me (in muppet language, so I can understand). How to interpret gearbox ratios. Nearly all the mfr's put them in their shiny car brochures but I don't have a clue what they actually mean. I suppose I will need a math degree to understand it but give it a go anyway.
Thanks in advance

Hi,
Not really an easy one to explain, But maybe this will help http://www.dropbears.com/u/utilities/sprocket.htm
It's all to do with the number of teeth on a gear being divided by the number of teeth on the gear that is meshing with it. This will give you the reduction ratio, ie: Gear with 28 teeth turning @ 100rpm is meshing with a gear with 10 teeth, this will give you a ratio of 2.80. If you multiply the 100rpm that the first gear is doing by this ratio it will give you the second gears rpm which will be 280rpm. Or something along those lines http://www.ltregister.f9.co.uk/graphics/biggrin1.gif border|EQU| 0 align|EQU| absmiddle >.
Hope this helps.
