The minimum pulley diameters recommended for standard Vbelts are shown in Table 3. Center Distance and Belt Length The relation between center distance and length is given by the following formula : This formula can be solved for center distance instead of belt length as follows : Note : The smaller the pulley diameter, the less the belt life. Do not use the pulleys which are below the ...

The positioning of rollers under the belt, on the conveying side of the belt, produces a good tracking effect due to the higher coefficient of friction, however, possible tracking marks on the belt cover must also be taken into consideration. The rollers can also be positioned above the belt on its running side. This is desirable in cases where the belt has a delie or highly .

Cylindrical rollers are installed at the belt edges and angled forward in the belt running direction. The skew angle, γ, should be 3° to 12° depending upon belt load, the friction between roller and belt, and on the belt speed. This method is not recommended to be used with thin belts of low transverse rigidity.

· Figure: Standard Vbelt (wrapped) Conversely, with the same pretensioning forces, much higher torques can be transmitted when using Vbelts instead of flat belts. To further increase the power transmission, two or more Vbelts can also be arranged parallel to each other. Figure: Vbelts . Vbelts can transmit significantly higher torques with the same bearing load than flat belts; however, the ...
