Connection System for Connecting a Component such as a Shaft, Hub, Bushing or the Like to a Gear Wheel, the Gear Wheel Comprising Helical Gearing

A connection system, comprising:

• a gear wheel that comprises:
• a toothed ring;
• helical gearing disposed on the toothed ring, the helical gearing having a tooth helix angle (β);
• and
• a first connecting section;
• wherein the toothed ring is made of a softer material than the connecting section;
• and
• a rotatable component connected to the gear wheel, the rotatable component comprising:
• a hub part;
• a second connecting section disposed between the toothed ring and the hub part, the second connecting section connecting the component to the first connecting section, wherein the second connecting section comprises a depression or elevation that is operatively connected to the first connecting section when the component is connected to the first connecting section, wherein the depression or the elevation has a connection helix angle (α) defined as 0°<α≦β;
• and
• wherein the toothed ring is made of a softer material than the second connecting section, and the second connecting section is made of a softer material than the hub part.
