Servometer Flexible Shaft Couplings Ensure Accurate Positioning
Servometer® precision electrodeposited, flexible shaft couplings provide low torque capabilities from 2 oz-in (1.4 Ncm) to 20 lb-ft (27 Nm), for shaft sizes ranging from .090 to 1 inch to ensure accurate positioning between motors, driven loads and feedback devices. They are also laterally flexible to accommodate shaft misalignment up to 31°, or parallel misalignments (shafts parallel but offset) up to .076 inch. In general, as flexibility increases, torque capacity decreases. For attachment to shafts, standard set screw hub, split hub with clamping collar or integral clamp hub styles are available.

Servometer nickel alloy bellows feature zero backlash, vibration damping capability, zero cyclic speed variation during 360° rotation, very low elastic windup, due to torsional rigidity, and low side thrust on bearings because of lateral flexibility. Other coupling types have either low windup or low side thrust; but not both.
Bellows couplings are ideal for use in critical applications such as resolvers, encoders, servos, motion control devices, and computers or in other precision motion control applications that require mechanically tight systems.

Designing with Metal Bellows Couplings
DESIGN ENGINEERS with precision rotary motion requirements such as instrumentation and fractional horsepower applications often choose electrodeposited nickel bellows because of their high performance characteristics like positive displacement , zero windup and low or minimal backlash. Servometer’s compact bellows couplings accommodate more than 30 times the angular misalignment and 15 times the compression or extension tolerated by other types of couplings.
Electroforming is the process of depositing thin layers of metal onto a mandrel through electroplating, dissolving the mandrel chemically, and leaving the plating as the final electroformed product. This white paper illustrates how electroformed components are manufactured and how they can be applied to a variety of applications.
