Abstract

A belt drive tensioning system for a motor drive positioning system, especially for X-Y digital plotters. The tensioning system employs spring-loading involving pivoting motion of a motor-mounted plate relative to a fixed plate to accurately preset and maintain constant the desired belt tension. A preferred embodiment provides a self-contained modular unit using two pivot bushings interconnecting the two plates.
