| 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 BiSlide, 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. |
