The math is not as difficult as it appears. Here''s the logic behind the centertocenter distance formula: 2C: Multiplying the centertocenter distance by 2 accounts for the belt length on the top and bottom of the pulleys Note: The pitch created by differing pulley diameters is addressed later in the equation. (D+d ÷ 2): This accounts for the belt length "wrapped around" the outer ...

contact usDescription. The Belt Drive block represents a pair of pulleys connected with a flexible ideal, flat, or Vshaped belt. The ideal belt does not slip relative to the pulley surfaces. The model accounts for friction between the flexible belt and the pulley periphery. If the friction force is not sufficient to drive the load, the model allows slip.
