Self-adjusting sleeve for aligning and transmitting loading between shafts
A recently granted patent (Publication Number: US11920637B2) discloses a method involving the alignment of two shafts, a first shaft, and a second shaft, in an end-to-end arrangement. The method includes coupling the shafts via a stem connector assembly and shear components, allowing independent alignment while transmitting various types of loading. The coupling is achieved by positioning a sleeve over the shafts and fastening it with shear components that partially recess into the shafts, ensuring the loading is not transmitted through the threaded portions of the fasteners. The alignment is facilitated by creating clearance spaces between the sleeve and the shafts and allowing the sleeve to self-adjust within these spaces.
Furthermore, the patent details a method where a sleeve with radial holes is used to align and couple the first and second shafts. The sleeve is fastened to the shafts using shear components extending through the radial holes, allowing for self-adjustment of alignment while transmitting different types of loading. Retaining mechanisms are employed to secure the fasteners within the shafts, ensuring that the loading is not transmitted through them. The method also involves creating clearance spaces between the sleeve and the shafts, facilitating the self-adjustment of alignment. The patent highlights the application of this method in scenarios where the first shaft functions as a valve stem and the second shaft as an operator stem, showcasing its versatility and potential in various industrial applications.
