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
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
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.
