Center Diameter Is The Distance Or Distances Between The Shafts Of The Pulleys In The.

Make sure the mark crosses both Reference belt width (w p) which depends on the belt type is multiplied by a factor that takes into consideration the desired design power of the system (p d), the reference transmission capacity (p s) and the engagement correction coefficient (k m). A person can measure the pulley’s diameter by turning the pulley so that the circular portion faces front.

Belt Length = 2C + 1.57 X (D1 + D2) + 1”.

Calipers work best for measuring this dimension. Lay the belt on a clean, flat surface. You can then determine how fast the smaller pulley is traveling.
