摘要： A connection of rotationally symmetrical components, in which minimal overturning torques and consequently minimal deformations of the supporting components are generated by generating the smallest, theoretically possible lever arm, on which the forces of the connection to be transmitted act. As a result, a nonpositive and positive-locking connection is obtained, in which the bolts no longer represent the dominantly loaded component. The maintenance and testing of the bolts is considerably reduced in all connections. Optimal flux of forces through the components close to the line of force application is achieved in the case of the tensioning of large rolling bearings. The requirements in terms of concentration of the contact pressure of the bearing tensioning in the vicinity of the line of force application are satisfied. In the case of a flange connection, optimal conditions are provided for tightness, besides a more economical manufacture, compared with the prior-art designs. Only extremely short bolts of a significantly smaller diameter are needed. A one-part sleeve surrounds two collars with tubular or cylindrical attachment provided on it. Wedge-shaped tensioning elements 2 are pulled in in the direction of the bolt axis by means of tension bolts between the inner, conical contact surfaces of the sleeve and the flat surfaces of the collars. The collars are tensioned with the sleeve via the wedge-shaped tensioning elements. The bolts are loaded only with a portion of the axial forces occurring.
