Single Strand Top Roller Chain Conveyor and Motor Calculation

This sheet is an estimation calculation of load and chain tension on the conveyor. Calculation also provided the required motor power (Sumitomo cyclo drive). Calculations are based on single strands drive chain and free roller on other side.

Input Information Conveyor & Product Input Weight of each conveyed product Wp Length of 1 product contact with chain Lp Qty of product: ~ Full accumulation ~ Transferring during full accumulation Conveyor length (sprocket C-C) L Tentative Chain & Motor Selection Tentative selection of chain (model) (top roller type) (mfg) Chain pitch Dp Top roller spacing Chain weight per meter M Max allowable chain tension Ft Max allowable load for chain roller F1allow ~ Conveying roller (top roller) F2allow ~ Base roller Selected motor kW size P'
