Abstract:
1. A gear drive mechanism with an anti-rattle device, comprising: a first gear rotatable about a first axis, a second gear rotatable about a second axis, wherein the second gear meshes with the first gear, and the second axis is located at a predetermined distance from the first axis, a first friction disk having a first friction rim surface that is rotationally coupled to the first gear and has a first frusto-conical shape, and a second friction disk having a second friction rim surface that is rotationally coupled to the second gear and has a second frusto-conical shape, wherein the first friction rim surface and the second friction rim surface are in circumferential contact with each other and thereby enabled to transmit a friction-based torque between each other, wherein one of the first and second friction rim surfaces is elastically biased against the other friction rim surface.
