The present invention relates to a gear wheel comprising an outer part (12) having a gear rim (14), an insert (16) which has an insert outer diameter (dEa) and a receptacle section (32) having an insert part inner diameter (dEi) for forming a shaft-hub connection, and a connecting part (18) which is arranged between the insert part (16) and the outer part (12) and which connects the insert part (16) and the outer part (12) in a formfitting and/or materially-bonded and/or friction-locked manner, wherein the connecting part (18) has a number of ribs (27) or the connecting part (18) is formed by a number of ribs (27), wherein the ribs (27) each extend along a tangent (T) which abuts a tangent circle (CT), wherein the tangent circle (CT) has a tangent circle diameter (dCT) which is larger than or equal to the insert inner diameter (dEi) and smaller than or equal to the insert outer diameter (dEa).
