The load capacity of PC/ABS spur gears and investigation of gear damage

Recently, Polyamide 66 and Teflon as plastic materials are widely used at the manufacturing of gear mechanism. The using of PC/ ABC materials provides many advantages due to fire, air and ultraviolet light durability and low moisture holding properties. In this study, the usability of PC/ABS composite plastic materials as spur gear was investigated. PC/ABS gears were tested by applying three different loading at two different numbers of revolutions on the FZG experiment set. As result of the experiments, load capability of PC/ABS materials was seen rather high, if one of the spur gear pair was steel (AISI 8620).
