Hexagonal V-belts are also known as Double V-belts. In simple terms it can be considered as two V-belts joined back to back. The neutral axis containing the tension member is exactly half way up the section.

Applications:
Hexagonal belts find their application in the drives where several pulleys in the same plane are to be driven in the clockwise and anti-clockwise direction simultaneously. The polyester tension cord placed at the centre of the construction provides the belt extreme flexibility and low stretch properties. It is because of this positioning of the cord that these belts are not subjected to any other forces as in the case of normal V-belts. These are also used in rice mills. However off late these belts are rapidly finding application in industrial drives.

Drive Calculation:
The drive calculation for double V-belts differs from the drive calculations of two-pulley drives. The effective lengths, rotational speeds, transmission ratios and belt speeds are determined by the effective pulley diameters. There is no requirement of special pulleys for these belts. We suggest that the customer should get back to us for assistance in using these belts.

Standards, Dimensions & Product Range:
For all practical purposes the length of double V-belts is considered as the effective length which is roughly the belt length at the centre.
