A rigid coupling is a unit of hardware used to join two shafts within a motor or mechanical system.
A device that is used to connect two shafts together for the purpose of power transmission.
Rigid Coupling:
• Used to connect shafts that are precisely aligned
Simple, economical
Low moment of inertia
Driving and driven shafts maintain relative angular position
Advantages:
Metallic versions can accommodate virtually o shaft misalignment, and non-metallic versions only trivial amounts of misalignment - and some suasion during operation will lead to some radial misalignment if both shafts are fully radials constrained.
Disadvantages:
Devices with enough internal clearances or flexible members (flexible shafts, spring washers, and so on) to accommodate any incidental shaft misalignment without a flexible coupling; consumer products, material handling equipment
Typical Applications:
All rigid couplings are precision-machined from bar, offering better strength, fit, and overall quality than cast or powdered metal couplings.
Machined to tighter tolerances than those of other manufacturers, improving fit between shaft and bore, dynamic balance, and so on.
Full range of sizes, materials, and shaft attachment options available

NO relative motion between the shafts.
Precise alignment of the shafts
Bolts in carry torque in shear. N = # of bolts.
Poor coupling selection Operation beyond design capabilities. The only way to improve coupling life is to
understand what caused the failure and to correct it prior to installing a new coupling. Some external signs that indicate potential coupling failure include:
Abnormal noise, such as screeching, squealing or chattering
Failed seals indicated by lubricant leakage or contamination
