트랙터 트랜스미션용 후진 아이들 기어의 3D 프린팅 특성

초록

This paper concerns the possibility of 3D printing reverse idle gears for tractor transmission. For the purposesof this experiment, idle gears were manufactured using a SLA 3D printer, FDM 3D printer, and throughmachining. The accuracy of the idle gears produced in these three different ways were evaluated by theproperties of their outer diameter, inner diameter, roundness, concentricity, parallelism, span, backlash, and geargrade. The tooth characteristics of the idle gears were evaluated by their profile, lead, and the pitch of thegears. The results of this experiment determined that the surface conditions created by the finishing process hada significant impact on the dimensional accuracy of the gears and the characteristics of their teeth.
