L=belt length (IN) C=center-to-center distance (IN) π=3.1416. D=large pulley's diameter (IN) d=small pulley diameter (IN) The math is not as difficult as it appears. Here's the logic behind the center-to-center distance formula: 2C: Multiplying the center-to-center distance by 2 accounts for the belt length on the top and bottom of the ...
Which Equals around application at belt center. Which Equals calculated belt length including 0 % stretch. Note: If the diameter of the pulleys at the belt center is unknown add one belt cross section to the diameter of the pulley when measured at the surface where the belt rides, i.e. the bottom of a belt groove or the face of a flat pulley.
The required take-up length is calculated as follows, where . S Sp = take-up length (m) L = conveyor length (m) ε = belt elongation, elastic and permanent (%) As a rough guideline, use 1,5 % elongation for textile belts. …
