Abstract
A shear section for a rotating arrangement includes an axially-extending shaft having a connection flange and a coupling flange adjacent the connection flange. The coupling flange includes an annular shoulder portion and an elongated neck portion extending axially away from the shoulder portion and disposed concentrically within the shaft. The shear section further includes a plurality of fasteners extending axially through the shoulder portion and the connection flange, and securing the shaft to the coupling flange. Each of the plurality of fasteners includes a shank region and a reduced thickness portion circumscribing the shank region.
Claims15
A shear section for a rotating arrangement, the shear section comprising:
- an axially-extending shaft having a connection flange;
- a coupling flange adjacent the connection flange, the coupling flange comprising:
- an annular shoulder portion;
- and
- an elongated neck portion extending axially away from the shoulder portion and disposed concentrically within the shaft;
- a gap between the annular shoulder portion and the connection flange;
- a wear ring disposed within the gap;
- and
- a plurality of fasteners extending axially through the shoulder portion and the connection flange, and securing the shaft to the coupling flange;
- wherein each of the plurality of fasteners comprises a shank region and a reduced thickness portion circumscribing the shank region.
A shaft assembly for connecting a drive device to a driven device, the shaft assembly comprising:
- an axially-extending shaft configured to attach to the driven device at a first end, the shaft further comprising a second end opposite the first end;
- a shear section located at the second end, the shear section comprising:
- an annular connection flange;
- a coupling flange adjacent the connection flange, the coupling flange comprising:
- an annular shoulder portion;
- and
- an elongated neck portion extending axially away from the shoulder portion and disposed concentrically within the shaft;
- wherein the coupling flange is further configured to attach to the drive device;
- a gap between the annular shoulder portion and the connection flange;
- a wear ring disposed within the gap;
- and
- a plurality of fasteners extending axially through the shoulder portion and the connection flange, and securing the shaft to the connection flange;
- wherein each of the plurality of fasteners comprises shank region and a reduced thickness portion circumscribing the shank region.
