Abstract
The invention relates to a method for producing a gear, said method including a step (a) during which a supporting core is made from a first polymer material, said supporting core comprising a hub, with a director axis (XX'), as well as a flange which extends radially from said hub to a peripheral flanged edge, said method then involves a coating step (b) which comprises producing a permanent coating layer, made of a second polymer material, by overmolding on the supporting core, including integrally both a front layer which covers the upper surface of the flange, and a side layer which extends said front layer axially by covering the outer radial surface of the flanged edge, such that said side layer forms a rim, the teeth of the gear being made in the radial body of said rim.
