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.
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.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
