A sealing device for a shaft passing through a partition wall includes a housing having an opening for a shaft to pass through, and an annular groove. The sealing device also has a rigid ring arranged with axial and radial play in the annular groove of the housing and having a through-opening for the shaft to pass through, and an annular groove on an inner circumferential surface of said through-opening. The sealing device also has an elastic ring arranged in the annular groove of the rigid ring, and a sliding band for bearing against the shaft, which is arranged circumferentially on the inner circumferential surface of the through opening of the rigid ring and covers the annular groove of the rigid ring and the elastic ring arranged therein, the elastic ring being urged against the sliding band.

An interference fit connection for a shaft comprises a hub having a conical through opening and a reduction sleeve having a cylindrical through opening for arrangement on the shaft and a conical outer circumference, where the cone angle of the conical outer circumference corresponds to the cone angle of the corresponding conical through opening of the hub. The hub 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 a ring which is arranged on the outer circumference of a sleeve portion of the first component, which sleeve portion surrounds the reduction sleeve, so as to surround this sleeve portion. The fiber-reinforced plastics material has a higher modulus of elasticity than the steel of the first component.

For a method for manufacturing a hollow shaft with at least one integral flange made of fiber composite, a plurality of intersecting windings of fiber material are applied onto a core. Moreover, the core has, for each flange, a radial spreader ring with an axial bearing surface. The windings are laid over an outer circumferential portion of the respective spreader ring and fixed. One or several inserts made of fiber material are inserted in the area of the spreader ring between the windings. The fixing of the wound fiber material is released, but is first still held on the spreader ring. Portions of the windings are then pulled off from the outer circumferential portion of the spreader ring and brought to rest on the axial bearing surface of the spreader ring in order to form a partial portion of a flange.

A force-fitting clamping connection includes a first metal clamping surface, a second metal clamping surface, and a clamping element for clamping the clamping surfaces against one another. The first clamping surface forms a hardened fine surface structure with microreliefs and microdepressions. The second clamping surface has a lower hardness than the first clamping surface. Preferably, the first clamping surface is surface-treated by sand-blasting, shot-blasting or embossing before the hardening operation. This allows permanently high friction coefficient values between the clamping surfaces. A flange connection includes such a clamping connection for transmitting high torques.
