In Reply to: RE: The Mechanics of Belt Creep posted by mosin on July 31, 2015 at 14:57:38
Right. I understand that about tape drive. I did say tape has very little belt creep.
I am trying to understand how force is transferred from belt to pulley. Are there two mechanisms depending on how stiff the belt is?
I did a quick search on flywheels and Mark Kelly. Here a couple results:
4/14/2014. There are a few [motors] which could be tweaked to run well when paired with a well designed external flywheel system but that raises the level of complexity and expense.
8/20/2017. One good example: before building the modelling I had deprecated the use of intermediate flywheels, saying that the multiple resonances would cause more trouble than they were worth. After modelling the dual motor / flywheel / rim drive set up HW showed last week I now know that I was completely wrong.
I am sure there more be Mark seems to have an open mind to flywheels.

Just friction.
That is the only mechanism to transfer the force from the pulley to the belt.
Belt the level of belt creep is determined by the level of elasticity of the belt - more compliant -> more creep. If there is no extension of the belt for a given tension per unit area (corresponding to the case when Young's Modulus for the material is infinite) there will be no creep.
However, materials with a high Young's modulus tend to offer less friction. So there us a trade-off between a belt with a low compliance which has less creep and a lower maximum torque compared with a compliant belt which offers a higher maximum torque but more creep.
A good trade off might be a belt by comprising a non-compliant core material (such as nylon strings) surrounded by rubber to increase the friction but without increasing compliance.

There is a good treatise of this Here.

he even knows what he will say two years from now!
