Re-think, pulley tension adjustment for bead roller and slip rollers
Hi All
After receiving the vee-belts in the post I soon realised the eccentric plummer block would not offer enough adjustment to tension both belts. So a re-think was needed and a solution to this problem. :headscratch:
I decided to manufacture a hinge plate the plummer block could be bolted too and operated via a single screw to tension the belts in conjunction with the motor adjustment and the eccentric plummer block. The eccentric was also difficult to adjust so a handle was made to rotate the shaft.

The photos below show the solution.

Eccentric casting housing machined to accept operating lever.

handle drilled and tapped at angle to give clearance on plummer block body. This tapped hole also locks the handle to casting.

The base plate was made from 6mm aluminium and the hinge was made from another piece of 6mm plate bolted together and drilled on joint center line to accept 8mm pin.

After setting up, the belts can be tensioned relatively easy and a new length belt for the bead roller is need as the one i purchased is to short but the slip rolls worked out a treat and have had them rotating via the drive.
New belt on order for bead roller.
