Method for manufacturing a toothed wheel with reinforcing strapping

A method for manufacturing a wheel, said method comprising a step (a) of producing a carrier core during which is produced, by injection of a first polymer material in a first mold, a carrier core which extends from a radially inner wall forming a bore having a main axis, corresponding to the axis of rotation of the wheel, up to a radially outer peripheral edge, said method then comprising a coating step (b) during which is produced, by overmolding operation on the carrier core, in a second polymer material, a coating layer in order to form a rim about the peripheral edge, in the radial over-thickness of the radially outer surface of said peripheral edge, wherein, during step (a) of producing the carrier core, is placed in the first mold, in the position substantially centered on the main axis, and before the injection of the first material, a preformed reinforcing ring, made of a third material called “reinforcing material” which is distinct from the first polymer material and from the second polymer material and which has a Young's modulus greater than that of the first material and than that of the second material, then is embedded, at least partially, said reinforcing ring, while injecting the first material, in the mass of said first material which forms the peripheral edge.
