1. An interference fit connection for a shaft (10), comprising:
a hub (1) having a conical through opening (5), and
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 second component made of fiber-reinforced plastics material is designed as an endless 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),
the fiber-reinforced plastics material having a higher modulus of elasticity than the steel of the first component.
