Abstract

Nowadays, this is even more challenging while additive manufacturing technology is used for prototyping, as well as the production of gearing systems. Presented is an optimization and characterization of the additively manufactured (AM) gears made of carbon-reinforced polyamide material in correlation to conventional polymer gearings. Based on the obtained results, the fatigue life data for AM carbon-reinforced Polyamide gears is calculated and compared to traditionally produced Polyamide 66-based gears. Results show that the durability of AM-produced carbon-reinforced Polyamide gears can be compared to conventional-produced Polyamide 66-based gears. Furthermore, deduced that wear of the AM-reinforced Polyamide teeth, can be closely connected with the meshing temperature in correlation with fatigue.

摘要

如今，当增材制造技术用于原型制作以及齿轮系统生产时，这一挑战变得更大。本文展示了与传统聚合物齿轮相关的、由碳增强聚酰胺材料制成的增材制造（AM）齿轮的优化与特性。基于所得结果，计算了增材制造的碳增强聚酰胺齿轮的疲劳寿命数据，并与传统生产的聚酰胺66基齿轮进行了比较。结果表明，增材制造的碳增强聚酰胺齿轮的耐久性可与传统生产的聚酰胺66基齿轮相媲美。此外，推断出增材增强聚酰胺齿的磨损可能与与疲劳相关的啮合温度密切相关。
