Abstract :
The goal of this work was to evaluate the wear behavior of PEEK gear wheels in a simulated space environment and their applicability in space mechanisms. With that study the question shall be answered if, despite a possible increased of the wear rate of a PEEK pinion, the accuracy requirements of a pointing mechanism can still be met.
