Abstract:Belt conveyor is a continual motion machine which materials can be transported、mainly be consisted of belt、iders、brrels、driving unit、straining unit、discharing unit、cleaner and itc. the structure of the machine anlysised on the fundermantal of priminer datats ,firstly,the stye of the belt conveyor determined by the stye of the machine,then the overall design of the belt converyer executed,the layout of transportation anlysised ;secondly the differential machine,A.C. commutator motor, elastic coupling, cross slide coupling and something else all are designedand ; the control chart of belt conveyor is also designed too,thebreakdown of operations and solutions of this belt converyor all are given in this essay.
Keywords: belt conveyor、 driving unit、 coupling
