OLDHAM FLEXIBLE SHAFT COUPLINGS
Advantages:
-
Protects driven component by serving as a mechanical "fuse" - an inexpensive replaceable plastic midsection shears under excess load
-
Protects support bearings by exerting consistently low reactive forces, even under large misalignments
-
Homokinetic transmission - driving and driven shafts rotate at exactly the same speed at all times
-
Zero backlash and high torsional stiffness
-
Electrical insulation
-
Accommodates large radial misalignment in a short length
-
Easy installation in blind or difficult installations when through-bores are used
-
Economically priced compared to other couplings with similar performance characteristics
-
Inexpensive replaceable wear element
-
Low moment of inertia
Disadvantages:
- Accommodates a relatively small angular misalignment
Typical applications:
Printing and copying machines; robotics and servo applications |
 |
Variations offered by OEP Couplings:
|
OC configuration - the classic Oldham coupling
|
OI configuration - a higher torque, higher stiffness variation without the mechanical fuse protective function
|
- Materials for midsection: Delrin - for general use; low friction, long wear. High-temperature high-performance thermoplastic - high temperature applications; low-friction-coated Urethane - vibration-dampening for high-shock or high-vibration applications.
|
- Materials for hub: Alloy 360 brass, alloy 2011 aluminum, and alloy 303 stainless steel
|
-
Shaft attachment options: Set screw without keyway, set screw with keyway, clamping without keyway, clamping with keyway
- Torque-limiting option - as detailed in this Case Study, we offer midsections that will break cleanly at a torque specified by the customer, as a replacement for other conventional, more costly torque-limiting devices
|
Advantages of OEP Couplings' Oldham configurations over those of other manufacturers:
- Higher torsional stiffness, longer service life, and more consistent performance from one coupling to another due to tighter machining tolerances and better surface finishes
- Higher static break torque and higher peak torque due to small but critical geometrical features, details of fabrication techniques, and the use of advanced materials and processes
- Higher RPM rating because of dynamic balance inherent in every coupling
