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.
Earlier this year paralyzed IndyCar drive Sam Schmidt did the seemingly impossible -- opening the qualifying rounds at Indy by driving a modified Corvette C7 Stingray around the Indianapolis Motor Speedway.
Wearables are changing the way we see ourselves. With onboard sensors that have access to our bodies, we are starting to know our physical selves like never before, quantifying our activity, our heart rate, breathing, and even our muscle effort.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
This year, Design News is getting a head start on the Fourth of July celebration. In honor of our country and its legacy of engineering innovation -- in all of its forms -- we are taking you on an alphabetical tour through all 50 states to showcase interesting engineering breakthroughs and historically significant events.
