Values of static and kinetic friction coefficient in micro slide bearings, consisting of journals and bushings (with the diameter of 3.5 mm) made of pairs of 5 polymer materials (16 chosen combinations of PA11, ABS, PC, PS bar drain board and PETP), were determined.A method of measuring static and kinetic friction coefficient, at various values of: load, rotational speed, and standstill time, as well as the structure of a dedicated test rig, were discussed.Chosen mechanical properties of click here polymers measured using indentation method, and conclusions from the conducted experiments, are shown.
The presented results provide key information for a proper choice of polymer materials, which are to work as a friction node.The biggest observed difference in the moment of friction among the tested slide bearings reached almost 40% (with respect to the highest value).
