Re: Gates Timing Belts

Hi!

An idler can increase the "wrap" of a small pulley. Avoid it if you
can, but it can be useful at times...

Seems intuitve to me that the force in tension applied to a shorter
length of belt will be spread "less" than the same force carried by a
longer section of the tension member. Which accounts for a short belt
failing sooner than a long one for a given torque...

Hope this helps.

P.S. Ditto, on the app engineers at gates.
