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
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
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.
