Ruland oldham couplings are comprised of two aluminium hubs with drive tenons
that mate with a floating center member. This design allows for easy sliding to
accommodate misalignment. Oldham couplings have light bearing loads since the
only resistance caused by misalignment is frictional. They also have the
advantages of electrical isolation. The couplings accommodate angular and axial
misalignment, and are useful in applications where parallel misalignment is
present. The replaceable center discs are available in two materials, offering
different levels of torsional rigidity.
Beam couplings from Ruland have overlapping spiral cuts in a single
piece of aluminium. The spiral cuts accommodate angular misalignment, parallel
misalignment and axial motion. The one-piece design and cut pattern ensure
backlash-free operation and allow for a small amount of shock absorption. Beam
couplings are useful when angular or complex misalignment is present. Stainless
steel versions are also available for applications requiring higher torque
The complete line of products includes shaft collars and rigid
couplings, and a full line of motion control couplings: beam couplings, bellows
couplings, oldham couplings, miniature disc couplings and zero backlash jaw
Because of the increasing ubiquity of wearable technology, it would be easy to think that design of wearable devices is routine and involves common design and engineering knowledge. Missed efforts in development will be remembered once the devices are used in the field
This grab-bag of new fasteners and adhesives work with a range of materials they can attach to, as well as a wide variety of applications. Several are for use in consumer applications, such as wearables or other compact electronic assemblies, and some of the adhesives have extended service temperature ranges and cure at room temperature.
As governments, associations, and NGOs around the world seek to protect consumers, national and regional standards are becoming mandatory, challenging manufacturers and making testing and certification necessary for any product developed and brought to market.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
