Gear

A gear having a tooth form shape includes, on a tooth root side of a tooth, (1) a first curved surface connected to a tooth face of an involute tooth form and convex in a direction opposite to the tooth face, (2) a flat surface connected to the first curved surface, and (3) a second curved surface c...

Beschreibung
Zusammenfassung:	A gear having a tooth form shape includes, on a tooth root side of a tooth, (1) a first curved surface connected to a tooth face of an involute tooth form and convex in a direction opposite to the tooth face, (2) a flat surface connected to the first curved surface, and (3) a second curved surface connected to the flat surface and convex in the same direction as the first curved surface. The shape of the flat surface in a normal plane is a tangent in contact with a tip side end of a trajectory of motion B of a tooth of a meshing partner gear and intersecting with a tooth form center line at a 30° angle. The shapes of the first and the second curved surfaces in a normal plane are circular arcs.
