Belt Widths The belt widths are as follows: 18, 24, 30, 36, 42, 48, 54, 60, 72, 84, and 96 inches. The width of the narrower belts may be governed by the size of lumps to be handled. Belts must be wide enough so that any combination of prevailing lumps and finer material does not load the lumps too close to the edge of the conveyor belt.

The friction coefficient (μ) of any belt is directly dependent upon the length of contact it has with its pulley. A simple rule of thumb may be used to assess the grip on any pulley, based upon a design grip (μ) being achieved for a contact angle (α) of 180° (Fig 2).; Toothed belt or chain μ = Veebelts μ ≈ Flat reinforced rubber belts μ ≈ Flat reinforced plastic ...

Calculation of VBelt Tensions And Shaft Loads

Determining Design Power (P d) The optimal belt drive tension is dependent on many factors. The goal is to tension the belts just enough to prevent them from slipping, however it is rare that all of the information necessary to do this is known. The formula for Design Power below covers the vast majority of belt drives.
