The conveyor belt is one of the widely used, interconnected transportation system in the today industry. conveyor belt, which isermanent means of transportation, has higher power and cargo transportation ability than the volume it needs. moreover, in many cases conveyor belt is the only economic means of transporting material from one point to.
Why static friction is significant for power transmission. static friction hasecisive function in nonpositive drives. this kind of transmission takes place in two and multipulley drives with flat belts, vbelts and polyvbelts, as well as on the driving pulley of conveyor belt installations and live roller conveyors.
Slippage of the belt in belt drives. the relative motion on the pulleys, which is always present due to the elasticity of the belt, is called elastic slip!lastic slip.elt speeds.ircumferential speed of the pulleys.oss of power.liding and adhesive areas.
