Abstract
Abstract Improved window regulator driving means for an automobile, comprising, in combination, a casing, a printed motor, epicyclic gearing driven thereby, and an output gear for driving the window regulator, which is characterized by a small size, narrow width and light weight for mounting the same inside a body of a door, and an appreciable reduction ratio for moving a glass sliding door at an adequate speed. The printed motor and epicyclic gearing driven thereby are housed within respective discrete chambers of the casing for filling the gear box with lubricating oil for lubricating the gearing. A removable emergency handle may be annexed for manual operation of the printed motor. The starting torque of the printed motor may be compensated by a joint formed in the output gear having a circumferential clearance therein.

Claim 1
Independent Claim
306 words
A window regulator driving means for an automobile, comprising, in combination, a printed motor, a double epicyclic gearing, an output gear and a housing therefor, said printed motor comprising a printed rotor, at least one permanent magnet, at least one brush, and a magnetic permeable plate, said magnetic permeable plate dividing said housing interior into discrete chambers, said printed rotor, said permanent magnet, and said brush occupying one of said discrete chambers for thereby forming a chamber for said printed motor, said printed rotor being rotatable in said discrete chamber, said double epicyclic gearing occupying another of said discrete chambers, whereby said another discrete chamber may be filled with lubricating oil for lubricating said gearing without interrupting said printed motor which is located within said first discrete chamber, said double epicyclic gearing comprising a primary sun gear, a primary planetary gear, a primary planetary gear carrier, a secondary sun gear, a secondary planetary gear, a secondary planetary gear carrier, and an internal gear, said primary sun gear being connected coaxially with said printed rotor, said primary planetary gear being larger than and in mesh with said primary sun gear and rotatably held on said primary planetary gear carrier, said secondary sun gear being connected coaxially with said primary planetary gear carrier, said secondary planetary gear being larger than and in mesh with said secondary sun gear and rotatably held on said secondary planetary gear carrier, and said internal gear being connected coaxially with said magnetic permeable plate and larger than and in mesh with said primary planetary gear and said secondary gear, and said output gear being adapted to be driven by said secondary planetary gear carrier and to drive said window regulator, whereby said window regulator is driven by said printed motor at a lower speed than a speed at which said printed motor runs.
