We welded a chain on the rims and drove it with help of sprockets on the shaft.

During the test, our idea of using a welded chain and sprocket failed. The sprocket teeth were not getting alligh=ned with the chain. The chin used to jump because of irregularity of the rim. and a lot of other issued like slippage and noise and vibrations.

Then coming back to basics.  We changed the sprockets with rollers and replaces the chain with plain circular rubber coated contact surface.
