Rotary expansible chamber devices include slant-axis rotary apparatus such as engines, compressors, pumps, and the like. Eccentric rotating members of such apparatus generate thrust and bending loads of high magnitude during operation thereof. The rotor shaft of the apparatus is subjected to severe bending and thrust loads which tend to fatigue various connections in the apparatus. The present invention provides a connection for counteracting the bending loads, including a bolt (21) extending through a rotor shaft (15), a nut (28) threadably mounted (27) on an end of the rotor shaft, and portions (30,31) of the rotor shaft (15) and bolt (21) which are disposed closely adjacent to the nut (28) and are further disposed in press-fit relationship relative to each other. Thus, bending loads imposed on the rotor shaft are transmitted directly to the bolt but not to the screw threads during operation of the apparatus.
