摘要
A helical gear is disclosed that is formed by an injection molding process in which the mold cavity is formed of mirror finished hardened stainless steel. The helical gear is disclosed in a gear box that entirely encase the gears, and may be integral with the housing of the toy. Furthermore, an “L” axle for gears is disclosed that provides a straight shaft portion that extends through the axle bearing aligned with the centerline of the gear and a bent portion that is seated in a slot recess in the wall of the gear box.
