vCalc.Belt Speed

The Speed of a Belt calculator computes the speed at which a linear length of belt travels around a pulley  based on the diameter (D)  of the pulley and the rotation rate (R).BeltSpeed-illustration.pngBelt

INSTRUCTIONS: Choose units and enter the following:

  • (D) Diameter of the pulley
  • (RPM) Rotation Rate of the pulley

Belt Speed (BS): The calculator computes the belt speed (BS) in meters per second.  However, this can be automatically converted to other velocity units via the pull-down menu.

The Math

The formula for the speed of the belt  is: 

               BS = (D •π • R)/(2π)  = ½•D•RPM
