You might want to look at slave drive for the rollers instead of all the belts and the drive shaft.

Provide a drive on the first roller of the conveyor and mount a double sprocket on one end of the shaft of each roll then chain drive each roller from the one before it. Very simple and easy to maintain.

This is a bulk handling forum.

Your unit load has inadequate rigidity to sit on a belt but can be carried over a series of line contacts? When the pallet friction gets big enough your membrane will buckle and nip twixt the rollers. If not, then we are not getting enough background on this forum; which as mentioned previously is a bulk handling forum.

You should examine the deflected shape of the membrane to determine the roller gap. Then you should consider the discharge regime. Presumably the membrane is light enough to float over the pallet...why not float them all the way all the time? ■

OK I tried. Now; the closest you can pitch the rollers as shown is twice the thickness of the drive band + the minimum shaft core that will take the radial/tensile bending loads; disregarding the minimum bend requirements of the bands. ■
