Design and Manufacturing of a Two-Stage Reduction Gearbox With 3d Printers

Abstract

ABSTRACT
 3D printers, which have been used in recent years, enable the conversion of a digital model into a physical 3D object by placing the filament material layer by layer and can help a wide variety of industries. Digital models can be created using software such as Solidworks and Catia or data created by a 3D scanner. 
 This study designed all parts of a two-stage reducer gearbox consisting of spur and helical gear pairs. The torques are calculated according to the input power. Shafts that can transmit torques are designed.
 On the other hand, gear wheels were calculated according to the total reduction ratio and were designed to transmit torques. CAD software (Solidworks) designed the gearbox parts, assembled them, and simulated them. Thus a digital model has been created. CAD models were transferred to the 3D printer. The slicing was done precisely using Cura software,
 On the other hand, the Marlin software reads the G codes created with Cura software sent from the computer. PLA (Polylactic Acid) was used as the filament material. The manufactured gearbox worked adequately, and the number of revolutions was reduced to 40 rpm from 800 rpm.
