ABSTRACT

This design mainly introduced the DT II belt conveyer survey, and its the main design calculation process, simultaneously also introduced in the belt conveyer some important parts. The belt conveyer is by the adhesive tape, the steel belt, the cotton tape and other belts (for example plastic tape, synthesis belt and so on) takes the transmission material the tool. Its main design calculation process as follows shows 1 driving influence and needs the transmission power the computation, main computation circumference driving influence computation (is main, resistance FH including computation, main special resistance FS1, attachment special resistance FS2, inclines resistance Fst) the transmission drum shaft power computation;

2 )transmissions drums, electrical machinery and drive combination choice;

3) conveyor belts tensities computation; 4 )conveyor belts tensities examination; 5) concave segmental arcs radius of curvature computation;

6 )tightening devices hang the installment quality again the computation;

7) opens applies the brake to calculate (separately considers idling, full load); Moreover an important link is must draw a chart, must complete as follows partially draws up the adhesive tape machine assembly drawing, the plan drives to install the assembly drawing, the plan frame assembly drawing, the request roller chart. The belt conveyer by the leather belt, the rack, actuates the drum, to change to the drum, the load bearing holds the roller, the return trip to hold the roller, the stretching device, sweeping clear and so on the spare part to be composed. In document detailed introduction.
