Abstract
A method includes disposing a first shaft and a second shaft in an end to end arrangement, positioning a sleeve over the end to end arrangement, coupling the sleeve to the first shaft via a first set of fasteners extending through a first set of radial holes in the sleeve and into the first shaft, coupling the sleeve to the second shaft via a second set of fasteners extending through a second set of radial holes in the sleeve and into the second shaft, and allowing the sleeve to self adjust the alignment between the first shaft and the second shaft while transmitting torsional, translational, or torsional and translational loading through the first set of fasteners and the second set of fasteners.

A method comprising:
- disposing a first shaft and a second shaft in an end to end arrangement;
- coupling the first shaft to the second shaft via a stem connector assembly;
- and
- independently aligning the first shaft and the second shaft while transmitting torsional, translational, or torsional and translational loading through the stem connector assembly.
A method comprising:
- disposing a first shaft and a second shaft in an end to end arrangement;
- positioning a sleeve over the end to end arrangement;
- coupling the sleeve to the first shaft and to the second shaft via a plurality of fasteners;
- and
- allowing the sleeve to self adjust the alignment between the first shaft and the second shaft while transmitting torsional, translational, or torsional and translational loading through the plurality of fasteners.
A method comprising:
- disposing a first shaft and a second shaft in an end to end arrangement;
- positioning a sleeve over the end to end arrangement, the sleeve comprising:
- a body with a plurality of radial holes extending through a wall of the body, the plurality of radial holes comprising:
- a first set of two radial holes positioned symmetrically disposed about a center plane extending through the body of the sleeve;
- and
- a second set of two radial holes symmetrically disposed about the center plane;
- coupling the sleeve to the first shaft via a first set of fasteners extending through the first set of radial holes and into the first shaft;
- coupling the sleeve to the second shaft via a second set of fasteners extending through the second set of radial holes and into the second shaft;
- allowing the sleeve to self adjust the alignment between the first shaft and the second shaft while transmitting torsional, translational, or torsional and translational loading through the first set of fasteners and the second set of fasteners.
