Shaft Misalignment Couplings
Shaft couplings are devices that connect two shafts together so that one shaft can drive the other. They absorb misalignment between two rotating shafts and are used in high power and high torque applications including motors, gearboxes, and other precision drive components. There are various types of motor shaft couplings, with many featuring zero backlash operation to handle heavy loads and speeds while reducing stress on bearings and other components.
Rigid shaft connector couplings accomplish this goal, but they do not deal with angular and radial misalignment or axial movement that may exist between the shafts. When rigid shaft couplings connect shafts that are mounted in bearing supports or couple to a gearbox or motor, the misalignment will immediately or eventually cause premature damage to the bearings that support the shafts. The misalignment transmitted through rigid couplings may also cause friction, heat, vibration, and noise.
Misalignment motor shaft couplers are designed to absorb the misalignment between the shafts. They come in various types including servo-high gain, spiral beam, spider jaw, and bellows and many other couplings to solve every type of misalignment problem and to protect the supporting bearings.
