and Plastics' thrust
rings act as rotating planetary carriers for helical shaped ring gears in
transmission assemblies. When precision molded of a high performance PEEK
formulation by MR&P, they incur less heat and surface abrasion resulting in
longer operating life than the aluminum components which they replace. † Their
material formulation included PEEK (Polyetheretherketone) providing high
temperature resistance (400 - 450F), carbon fiber providing high wear
resistance and PTFE for reduced friction. The manufacturer says in addition to
proving to be more durable over time, the MR&P design was 50 percent
lighter and cost significantly less than the aluminum thrust rings.
assembly benefits were accomplished with the new MR&P thrust ring design. The
previous aluminum component design had two locating holes requiring tedious
riveting and assembly. Accurate alignment was required to avoid wasted
components and potential performance issues. The new MR&P design eliminated
the locating holes and added self-aligning features for easy and fast press-fit
assembly. Scrapped parts thus were eliminated.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicleís parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but thatís just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
Design engineers need to prepare for a future in which their electronic products will use not just one or two, but possibly many user interfaces that involve touch, vision, gestures, and even eye movements.
