You have your two flanges that mount on the shaft and then you have a rubber insert. A sleeve coupling consists of three basic components. Certain types of couplings are better at accommodating this than others.Ī sleeve coupling is an elastomer-in-shear coupling with rather generous misalignment limits. This is common in sleeve-bearing motors where the rotor wants to find its magnetic center. In many applications, you need a coupling that can that accommodate some kind of axial misalignment, basically to accomodate thermal growth. …Another type of misalignment is axial misalignment. Here, Smihal covers some best practices for understanding axial misalignment in sleeve coupling installation. *Below is an excerpt from part two of a Design World webinar presentation by John Smihal of TB Wood’s Inc.
