Patent ID: 7738323

Claim:
An arrangement for mechanical interfacing of a micromotor of the Micro Electro Mechanical System type with a toothed wheel, the arrangement comprises: (i) a toothed wheel; (ii) a central shaft defining a central axis; (iii) a micromotor, produced in an upper layer of a plate made of crystalline or amorphous material, wherein the micromotor comprises at least one linear actuator; (iv) a rotor, arranged above the plate, wherein the rotor is driven in rotation by the at least one linear actuator; (v) a pinion coaxial with the rotor and arranged above the rotor, wherein the rotor is disposed to rotate about the central axis, wherein the rotor and the pinion are connected in rotation by at least one off-set pin that is received in an associated hole formed in the rotor so as to be disposed off a center of the rotor, wherein operating play is provided between the rotor and the pinion so that the rotor and the pinion are coupled in rotation angularly, said operating play including a radial clearance so that the rotor and the pinion move independently in a radial direction with respect to the axis of the central shaft, and wherein the pinion meshes with the toothed wheel.
