Sleeve Coupling

Understanding Sleeve Couplings

Sleeve couplings are one of the simplest types of rigid shaft couplings. They function by fitting snugly over the ends of the two shafts to be joined, secured typically by keys and set screws (for solid sleeves) or clamping bolts (for split sleeves).

Key Characteristics:

• Rigid Connection: Provides a direct, solid connection between shafts with no flexibility.
• Zero Misalignment Capability: Requires shafts to be in near-perfect alignment during installation and operation. Any misalignment can cause high stress and premature failure of shafts or bearings.
• Simple Design: Consists of a single sleeve (solid type) or two halves (split type) and fasteners.
• Cost-Effective: Generally the most economical type of coupling due to its simplicity.
• Compact Size: Offers a small outside diameter for the torque transmitted.
• Ease of Installation (Split Type): Split sleeve couplings (Muff couplings) can be installed or removed without moving the connected machinery.

Types:

• Solid Sleeve Coupling: A single piece cylindrical sleeve. Requires axial access to slide onto shaft ends.
• Split Sleeve Coupling (Muff Coupling): Made in two halves that bolt together around the shafts. Allows for installation where axial access is limited.
