Hi,
I want to drive a milling machine spindle from a motor, and think a belt
drive is the best way to go.
Question is, how do I work out what belt to use?
The motor runs at 10,000 rpm and a 1:3 ratio sounds good. 600 W, one
problem might be that the shaft centers are 3" apart.
Any suggestions? Thanks,
-- Peter Fairbrother

With only 3" between shaft centres, I think you will be struggling to
get any belt typeto work as your pulleys would need to be quite small.
At 10K rpm aswell, you might have additional issues.
I would have thought gears would have been a better solution here.

I think that the only easy way to go would be with toothed 'timing'
belts, but gears would be a more professional method, but require more
engineering to get the centres and meshing correct. I assume you will
be working with small cutters as3300 rpm is quite fast. If you wish to
get things going slower, a layshaft could be used to give a further
3:1 reduction ie to 1100 rpm, I made one like this some years ago to
give two sets of 3 speeds by incorporating a pair of step pulleys.

According to Gates DFpro, it's doable with toothed belts/pulleys.
Link below shows the possible combinations.

Thanks.
I may go with a poly-vee belt instead, but that's useful to know.
