Bevel Gears + Hunting Tooth

[Steve]

I understand it's bad practice to have the ratios between pinions set such
as the same teeth always mesh - is this true for bevel gears? I'm going to
cut a couple of bevel gears using the parallel depth method and a pair with
15 teeth, 40DP each would be best, but 15 teeth and 18 teeth I can live
with if the "hunting tooth"(?) is likely to be a material issue. The shaft
will probably be turning at around 500 - 1000rpm.

Depends on the application. If you were designing a differential for a
production car then yes it is important but for a one off?? Only you can
tell. Ask yourself how much work it will do, will a bit of noise when it
wears be an issue and how much grief will you have in N years if you
have to replace the gears?
Getting a good tooth geometry would be more important to my way of thinking.

Thanks Bob. Sounds like I can cut them 1:1 which will mean only one setup
and a better fit between the pair. This won't run long enough to get worn!

You can tell I'm learning - I've started looking for the difference between
the "correct" method and the best method for the job at hand!

I would be more concerned about making 'straight' teeth ie spurs with
angled reeth, tou should be making helicals, if you have a problem, I
can help.
