Multiple-output transmission

摘要

A multiple-output transmission includes a drive motor and one or more stacked layers. Each layer includes one or more output gears, a drive gear, coupled to be driven by the drive motor, at least one idler gear, engageable with the drive gear, and means for indexing the at least one idler gear between multiple selectable indexing positions, thereby to selectively engage one or more of the output gears.

1. A multiple-output transmission, comprising:
a first turning mechanism, adapted to bi-directionally rotate about a first axis; a first drive gear, disposed adjacent to the first turning mechanism and adapted to rotate about a second axis that is at least parallel to the first axis; a drive motor, configured to drive the first drive gear; a plurality of first idler gears, rotatably disposed upon the first turning mechanism and engaged with the first drive gear; a plurality of first output gears, each first idler gear being positioned to engage one of the plurality of first output gears when the first turning mechanism rotates to one of multiple selectable indexing positions, the plurality of first output gears being selectively driven in multiple combinations depending on the selected indexing position; and an indexing mechanism, configured to selectively rotate the first turning mechanism in either direction between the indexing positions.
