The belt has that aramid fiber band woven, spun as the tension section; The rubber blend cover is made as a solution around this aramid fiber.
Under load the belt is like a steel band.
...Belt rubber deforming...
yes;
The rubber must deform to follow the sheave path when the belt is pulled.
...Belt stretch?...
No!
L]...belt side pressure
J]...How do you calculate this? How would you use the values?
L]...turning radius
J]...Ok.
L]...belt speed, etc.
J]...What would the values tell you? Something good? Something bad?
L]...When in overdrive, the secondary clutch is spinning faster than the primary, and this high belt speed yields efficiency loss due to belt tension and centrifigul force.
J]...Ok then, what will you do with this information? Will it help you calculate something?
L]...I'd also imagine that having less contact area with the secondary while in overdrive lends to more slippage.
J]...GREAT! Now we're getting somewhere. Now you are talking with a principle.
Q]...What do you do to reduce belt slip?
A]...Grab it harder.
Question]...How do you grab the belt harder?
Answer]...Increase the side
FORCE.....not "pressure" Do you weigh 195 lbs pressure? No, you weigh 195 lbs...gettit?!!
Question]...How do you increase the side force?
Answer]...Increase spring force and/or use lower helix angle
vs. previous values.
Question]...How do we know to make a change in the right direction?
Answer]...How do you know there is slippage?
Comments]...Hot temperatures
Question]...Why is there hot temperatures?
Answer]...Belt slip
Question]...How do you reduce belt slip?
Answer]...Grab the belt harder.

Efficiency losses due to, blah blah blah... Well we know inefficiency reveals high temperatures, then who cares about all that stuff - Yes it's good to know, however don't let that stop you from experimenting.
*Inefficient = belt slip = high temperatures. Efficient = less belt slip = lower temperatures.
Now would this "*" be more important to know than "efficiency loss, because" ?
Now only need to care how to reduce temperature.
Clamp the belt harder to reduce temperature and tell me anything else that matters.
How do you know how to grab the belt?.....Know
