A waveguide extends through the adaptor, from the first end to the second end.

Abstract: 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 As a result, a nonpositive and positive-locking connection is obtained, in which the bolts no longer represent the dominantly loaded component.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.

Abstract: A plate for spreading bolt loading around the horizontal joint flanges of a turbomachine, such as a steam turbine, is provided. The plate is contoured so that its surface area substantially matches that of the surface of the steam turbine flange against which the compressive load associated with the joint bolt preloading is applied.

The plate serves to distribute the compressive joint loading around the entire surface of the flange, thereby eliminating the locally high compressive stresses that can cause creep and yielding in the flange. Spherical counter bores are machined in the plate bolt holes and spherical washers are installed between the plate and the nuts so that misalignment of bolt holes does not cause the nuts to impose bending forces on the bolts.
