This study presents the results of detailed wear process examination on polyformaldehyde gears under both dry and lubricated conditions. A multi-purpose durability test rig was employed to study the wear performance of polyformaldehyde gear pairs. The wear behaviors of polyformaldehyde gears under dry and oil-lubricated operating conditions were characterized via measurements of gear tooth surface micro-topography and tooth profile deviation. Under the dry running condition, a hump and a gully appear on the tooth surface in the pitch line area of the driving gear and the driven wheel, respectively. The largest amount of wear was observed around the tooth root of the driving gear. However, the gear tooth wear pattern with lubrication is different from that under the dry running condition.

这项研究提出了在干燥和润滑条件下对聚甲醛齿轮进行详细磨损过程检查的结果。采用了多功能耐久性试验台来研究聚甲醛齿轮对的磨损性能。通过测量齿轮齿表面微观形貌和齿廓偏差，表征了聚甲醛齿轮在干燥和油润滑的工作条件下的磨损行为。在空转条件下，在主动齿轮和从动轮的节线区域中的齿面上分别出现隆起和沟纹。在驱动齿轮的齿根周围观察到最大的磨损。但是，带润滑的齿轮齿磨损方式与空转条件下的不同。
