Re: Possible to do multi-speed transmission with v-belt?

on a car, to get the alternator belt tight, you normally have to pry the alternator with a crow bar, and put a significant amount of force on it.

BTW, modern Vbelts dont streach like they use to. I have not needed to adjust a Vbelt tension in the last 10 years.

The reason why belts are still around after all these years is they can perform 3 functions at the same time:

1. gear reduction
2. power transmission (from one pulley to another)
3. clutch mechanism. Its pretty tricky to get a gear or chain to engage under load smoothly :^)

and one other advantage to belts, they can be very quiet compaired to gears or chains!
