Abstract:
A geared motor (10) with a flat construction as a sub-assembly of a motor and a gear drive in a housing with an axially short housing/base body (11), that is fitted on one side of a yoke disc (14) with a motor (13) having a disc-shaped rotor geometry and on the opposite side with a gear drive (15), that is driven through the yoke disc (14) by the motor (13) and is fitted with a coaxially rotating driven ring (20), while the driven ring (20) has internal teeth (28) that are axially adjacent to an inner gearing (26) of a support ring (27), characterised in that an H-shaped housing/base body (11) is fitted with a drive within its rim (12) surrounding the yoke disc (14), wherein the yoke disc (14) is broken out like spokes or is enclosed by a flat face, the driven ring (20) being a part of the wave drive, while simultaneously both internal gearings (28, 26) mesh with a portion of a gear rim (25) of a radially flexible transmission element (19) that has a hub (23) continuously expanded by a motor-driven eccentric,wherein the rim sleeve (12) supports substantially flat casing covers (29, 32), wherein the casing covers (29, 32) serve as axial stops for the parts of the gear drive (15) or, respectively, of the motor (13) on two sides of the base body (11), wherein the parts are rotating below the casing covers (29, 32), wherein a disk shaped rotor (51) of the motor (13) together with the motor shaft (16) and the drive element (18) is formed as a single piece and wherein the lead guide required for an electromotoric function is supported applied in Molded Interconnection Device MID technology.
