Plastic Transmission Thrust Ring Converted From Aluminum to Molded PEEK Material

Plastic Transmission Thrust Ring Converted From Aluminum to Molded PEEK Material

Minnesota Rubber 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.

Important 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.
