ABSTRACT:
The invention refers to a method for interconnecting two flange-provided shaft ends by means of taper pin bolts and expander sleeves co-operating therewith as well as a shaft coupling assembled accordingly. The shaft coupling is intended to transfer very large torques and great bending stresses, e.g. in steam and nuclear power plants. The new shaft coupling and the mounting method enable the use of the same bolt as an expansion-shell bolt, for achieving the desired press fit, and as a set bolt, which can be pre-loaded to function like a hard-tightened fitting bolt. This has been achieved on one hand by preventing the expander sleeve from moving axially, when the bolt is tightened, and on the other hand by abolishing the friction between the sleeve and the bolt after achieving the desired press fit, whereupon the bolt is further tightened up close to the yield point of the bolt. In this position the bolt is fixed by means of the nut so that the bolt preserves the desired press fit as well as the pre-load.
