This article focuses on wear tests of spur gears made with the use of additive manufacturing techniques from thermoplastic materials. The following additive manufacturing techniques were employed in this study: Melted and Extruded Modelling (FDM) and Fused Filament Fabrication (FFF). The study analysed gears made from ABS M-30 (Acrylonitrile Butadiene Styrene), ULTEM 9085 (PEI Polyetherimide) and PEEK (Polyetheretherketone), and the selection of these materials reflects their hierarchy in terms of economical application and strength parameters. A test rig designed by the authors was used to determine the fatigue life of polymer gears. Gear trains were tested under load in order to measure wear in polymer gears manufactured using FDM and FFF techniques. In order to understand the mechanism behind gear wear, further tests were performed on a P40 coordinate measuring machine (CMM) and a TalyScan 150 scanning instrument. The results of the gear tests made under load allow us to conclude that PEEK is resistant to wear and gear train operating temperature. Its initial topography undergoes slight changes in comparison to ABS M-30 and Ultem 9085. The biggest wear was reported for gears made from Ultem 9085. The hardness of the material decreased due to the loaded gear train's operating temperature.
本文重点关注采用热塑性材料通过增材制造技术制造的圆柱齿轮的磨损试验。本研究采用了以下增材制造技术:熔融沉积成型(FDM)和熔丝制造(FFF)。该研究分析了由ABS M-30(丙烯腈-丁二烯-苯乙烯)、ULTEM 9085(聚醚酰亚胺)和聚醚醚酮(PEEK)制成的齿轮,这些材料的选择反映了它们在经济适用性和强度参数方面的层级关系。作者设计的试验台用于确定聚合物齿轮的疲劳寿命。齿轮系在负载下进行测试,以测量使用FDM和FFF技术制造的聚合物齿轮的磨损情况。为了了解齿轮磨损背后的机制,还在P40坐标测量机(CMM)和TalyScan 150扫描仪器上进行了进一步测试。在负载下进行的齿轮测试结果使我们得出结论,聚醚醚酮耐磨且耐齿轮系工作温度。与ABS M-30和ULTEM 9085相比,其初始形貌变化轻微。据报道,由ULTEM 9085制成的齿轮磨损最大。由于负载齿轮系的工作温度,材料的硬度降低。
