With conveyor aspect ratio (conveyor length to belt width) in excess of about 5 to 1 and in installations with reversing operations, it is advisable to crown both, head pulley and tail pulley. Following this method, a correctly aligned belt can be maintained in its central position as long as there is no excessive deflection of the pulleys.

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 pulleys Note: The ...

Step 1: First, measure the outside diameter (OD) of the pulley. Step 2: Next, measure the pitch diameter (PD). This is the measurement that represents the diameter of the belt itself as it rides in the pulley. This step is not necessary if you already know your V-belt size or if the pulley and belt are greatly worn. Step 3:

· 1. Mark a line across the belt with a white marker. Hold the belt in 1 hand and take a white marker or a piece of chalk and mark a line on the outside of it. Make the line all the way across the width of the belt. [1] Make sure the line is thick enough to be visible and won''t rub off too easily while you''re measuring.

· When the physical constraints of a conveyor system will not allow you to properly size your shaft diameter, shaft turndowns may be utilized to increase the load capacity of a pulley. A turndown is where a larger shaft is turned down to a smaller diameter at the ends, while retaining the larger diameter through the pulley.

All conveyors require an additional belt tension in order to allow the pulley to drive forward an effective tension without slipping. In a case of a simple horizontal conveyor T1 is the sum of the effective tension Te and the slack side, the tension T2. T 1 = T e + T 2 = For the inclined conveyor, additional tensions are induced due
