The belt conveyor is a transmitting mechanical to drive materials byfriction in a continuous manner, it can form a delivery processes between thefeed point and the discharge point; if matching with corresponding technologicalprocess, they can be a rhythmic flow transport line.
The worm is a keycomponent of the belt conveyor; its stress force determines the quality of workperformance and length of service life. So, it is necessary to analyze thestress force of the worm.
