Interference fit connection for a shaft

An interference fit connection for a shaft (10), comprising

• a hub (1) having an elongate sleeve portion (2), a flange portion (3) which protrudes radially from the sleeve portion (2) and is provided with attachment structures for coupling to a further component, and a conical through opening (5);
• a reduction sleeve (6) having a cylindrical through opening (7) for arrangement on the shaft (10) and a conical outer circumference (8), the cone angle of the conical outer circumference (8) corresponding to the cone angle of the corresponding conical through opening (5) of the hub (1),
• wherein the hub (1) is a two-component part having a first component made of steel and a second component made of fiber-reinforced plastics material, the fiber-reinforced plastics material having a higher modulus of elasticity than the steel of the first component;
• wherein the second component made of fiber-reinforced plastics material is designed as a ring (9) which is arranged on the outer circumference of a sleeve portion (2) of the first component, which sleeve portion surrounds the reduction sleeve, so as to surround this sleeve portion (2), and
• wherein sleeve portion (2) has a radially gradated region (2a) reduced in diameter to form a step and the ring (9) made of fiber-reinforced plastics material is arranged in the gradated region (2a).
