Abstract
. The slippage often occurs between conveyor belt and driving drum, reduces the transmission efficiency and even causes accidents due to lack of enough friction. By the analysis of friction drive principle in belt conveyor, three ways were presented to increase the frictional traction. Learning from the bionic tribology theory, we proposed a new structure design of the drum coating layer surface. The micro contact area of fly's seta that can adhere to any surface was taken as a prototype, and its microscopic structure was analyzed, then the surface structure of coating layer with recess long blocks was designed, finally, the solid modeling was created with CAD software. The new surface has sub atmospheric pressure absorption. The purpose is to increase the friction between conveyor belt and driving drum, and to avoid the slippage.
