Claims
- 1. A gear-motor closing part drive, comprising:
a drive-side gear wheel; and a driven-side carrier that is in rotary driving engagement with the drive-side gear wheel; wherein at least one of the gear wheel and the carrier has integral elastic spring elements; wherein the other one of the gear wheel and the carrier has cams that are configured to press against the integral elastic spring elements in order to provide mutual stop absorption when a mutual relative rotational movement between the gear wheel and the carrier occurs because movement of the carrier is inhibited, while the gear wheel continues to be driven; and wherein the spring elements comprise spring segments, which extend substantially tangentially, which have stopping bevels, and which are arranged such that they are radially elastically deformed by the cams, when the cams slidingly run against and press against the stopping bevels.
- 2. The gear-motor closing part drive of claim 1, wherein the stopping bevels are configured such that the mutual rotational relative movement between the gear wheel and the carrier is free from self-locking between the spring elements and the cams.
- 3. The gear-motor closing part drive of claim 1,
wherein the spring elements comprise connections that are formed onto and spaced around at least one of the gear wheel and the carrier and that support the spring segments; and wherein, when the mutual rotational relative movement occurs, the cams are configured to elastically push the spring segments into recesses that are arranged between the connections of the spring elements.
- 4. The gear-motor closing part drive of claim 3, wherein a degree of the radial elastic deformation of the spring elements is limited by a limit stop that is integrally formed onto at least one of the gear wheel and the carrier.
- 5. The gear-motor closing part drive of claim 1, wherein the gear wheel and the carrier are configured to provide a play-free fit when the gear wheel and the carrier are arranged in a mutual operating position.
- 6. The gear-motor closing part drive of claim 1, wherein the gear wheel and the carrier are configured as a unitary injection molded part, composed of parts that can be drawn in an axial direction only.
- 7. The gear-motor closing part drive of claim 1, wherein the carrier further comprises a driven element.
- 8. The gear-motor closing part of claim 7, wherein the carrier with the driven element is integrally injection molded as a unitary piece.
- 9. A device, comprising:
a gear wheel; a carrier wheel that engages the gear wheel and rotates about a common axis with the gear wheel; a plurality of spring elements; and a plurality of cams that actuate the spring elements during relative rotational movement of the gear wheel and the carrier wheel; wherein the spring elements and the cams provide engagement between the gear wheel and the carrier wheel, and dampen the relative rotational movement between the gear wheel and the carrier wheel.
- 10. A method for producing a gear-motor closing part drive, comprising:
producing a gear wheel and a carrier as separate, axially superimposed injection molded parts that are cast in a common injection mold; and connecting the gear wheel and the carrier via integrally injection-molded connecting brackets that are pulled off when the gear wheel and the carrier are fit together from an injection molded position into a mutual operating position in order to form an assembly unit.
- 11. A method, comprising:
in an injection molding operation, forming a gear wheel and a carrier, wherein the gear wheel and the carrier are spaced from one another along a common axis, wherein the gear wheel and the carrier are connected by a plurality of brackets, and wherein the gear wheel, the carrier, and the brackets are integrally formed of injection molded plastic; and breaking the connection formed by the brackets by forcing the gear wheel and the carrier into an overlapping position on the common axis.
