ABSTRACT

The aim of this design is to alter the conveyor belt, mainly through adding the line friction drive equipment.

What is mainly introduced in the present paper is as followed: First, to introduce the composition of conveyor belt, the work principle and the correlated parameter. Second, to introduce the principle of line friction drive and the correlated calculation principle. Finally, to transform the design calculation and verify it.

In this design several kind of plans are contrasted which are used to transform the conveyor belt, finally the line friction drive equipment is determined to use with. The design mainly involves: the choosing of adhesive tape (fabric level), the examination of adhesive tape, the length calculation of auxiliary engine and position determination, and auxiliary engine composition! Key words: Conveyor belt, electric motor, friction.
