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 with a helical gearing having a tooth helix angle (β);
• a first connecting part that forms a first connecting section;
• wherein the first connecting part is made of a first material;
• wherein the toothed ring is made of a second material, wherein the first material is relatively softer than the second material;
• and
• a rotatable component connected to the gear wheel, the rotatable component comprising:
• a hub part made of a third material, wherein the second material is softer than the third material;
• 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 connection helix angle (α) and the tooth helix angle (β) have the same sense of rotation.
