Abstract
Gear mechanism (10), in particular for adjusting moveable parts in a motor vehicle, comprising a spur wheel (14) which is provided with external teeth (16) and meshes with an internal gear (18) that is provided with internal teeth (20), wherein the number of internal teeth (20) to generate a certain gear step-up ratio is greater by at least one than the number of external teeth (16) and the spur wheel (14) and the internal gear (18) perform an eccentric movement relative to one another, wherein the eccentric movement is directed exclusively by means of the matching tooth geometry of the internal and external teeth (20, 16).

Gear mechanism (10) comprising a spur wheel (14) which is provided with external teeth (16) and meshes with an internal gear (18) that is provided with internal teeth (20), wherein the number of internal teeth (20) to generate a certain gear step-up ratio is greater by at least one than the number of external teeth (16) and the spur wheel (14) and the internal gear (18) perform an eccentric movement relative to one another, characterized in that the eccentric movement is directed by means of the matching tooth geometry of the internal and external teeth (20, 16), and wherein the outside diameter (64) of the external teeth (16) is greater than the inside diameter (66) of the internal teeth (20).
Gear mechanism (10) comprising a spur wheel (14) which is provided with external teeth (16) and meshes with an internal gear (18) that is provided with internal teeth (20), wherein the number of internal teeth (20) to generate a certain gear step-up ratio is greater by at least one than the number of external teeth (16) and the spur wheel (14) and the internal gear (18) perform an eccentric movement relative to one another, characterized in that the eccentric movement is directed by means of the matching tooth geometry of the internal and external teeth (20, 16), and wherein the spur wheel (14) is coupled with a drive element (12, 32) rotating around an axis (28) or a driven element (26, 33), wherein the coupling (30, 34) is embodied to be radially flexible vis-à-vis the axis (28).
Gear mechanism (10) comprising a spur wheel (14) which is provided with external teeth (16) and meshes with an internal gear (18) that is provided with internal teeth (20), wherein the number of internal teeth (20) to generate a certain gear step-up ratio is greater by at least one than the number of external teeth (16) and the spur wheel (14) and the internal gear (18) perform an eccentric movement relative to one another, characterized in that the eccentric movement is directed by means of the matching tooth geometry of the internal and external teeth (20, 16), and wherein the internal gear (18) is coupled with a drive element (12, 32) rotating around the axis (28) or a driven element (26, 33), wherein the coupling (30, 34) is embodied to be radially flexible vis-à-vis the axis (28).
Gear mechanism (10) comprising a spur wheel (14) which is provided with external teeth (16) and meshes with an internal gear (18) that is provided with internal teeth (20), wherein the number of internal teeth (20) to generate a certain gear step-up ratio is greater by at least one than the number of external teeth (16) and the spur wheel (14) and the internal gear (18) perform an eccentric movement relative to one another, characterized in that the eccentric movement is directed by means of the matching tooth geometry of the internal and external teeth (20, 16), and wherein the coupling (30) features an elastic element (34), in particular an elastomer, which is embodied to torsion-proof and radially moveable.
