Abstract
A spool assembly and method of use is disclosed having generally a first and a second mating portions which can mate along a longitudinal axis of the spool to retain a belt therein. The mating surfaces of the first and second mating portions can take a variety of geometries or splines which can efficiently retain the belt while maintaining a suitable transmission ratio. In an exemplary embodiment, the spool exit curve for the retained belt can be radially inward of a majority of the spool to reduce the overall diameter of the spool. In some exemplary embodiments, the spool can be mounted within a motor and rotated thereby to spool and unspool the belt.
