Cross belt drive:
In this type of belt drive, the shafts are parallel to each other just like in open belt drive but the belts are in cross configuration and moving opposite to in each other in direction.In this configuration, the same layout of one shaft is bigger than the other is applied. Crossed belt drive has more tension on the side which is acting as the driver i.e. the direction in which the belt is being moved. The side being pulled in known as the tight side and the other one is known as the slack side.
Quarter Turn Belt Drive:
This type of belt drive is also known as right angle belt drive. In this configurations, the shafts are at the right angle and move in one direction.This provides for a unique problem and that is the belt running down the pulley, to overcome this problem the width of the shaft is quarter times more than the width of the belt. Hence the name quarter turns belt drive.
Compound Belt Drive:
As the name suggests, compound belt drive is a complex arrangement of shafts and pulleys where power is transmitted from more than one shaft utilizing a number of pulleys. It is generally used in a complex application environment.
