Belt driven

Belt driven

The belt drive assembly is the solution when long travel and high speeds are required.
The belt system can be manufactured up to 220 inches (5.6 meters) travel versus 80 inches (2.0 meters) of travel for the standard lead screw drive. Speeds as high as 3 meters per second can be achieved using direct drive motors and high powered controllers. Several gear reduction motor options are available for high resolution and lower speed applications.

The belt drive assembly consists of a motor/gearbox, mounted 90 degrees to the traverse. The output of the motor or gearbox is directly coupled to a stainless steel pulley which drives a steel reinforced timing belt. Compared to the screw motion, the belt version´s overall length and width is greater, there is a 0.375″ under-hang at the motor, and the belt accuracy is less. Special precautions need to be taken when using the belt drive vertically since it does not «self-lock» to prevent back driving like a fine pitch lead screw drive. 
The belt drive´s high efficiency make it an ideal choice for moving light loads at high speed and for continuous duty applications.
