Sažetak
Increase in global competitiveness, requirements for smaller parts and space saving have led to development of advanced processes for gears manufacturing. Engineers and researchers are constantly searching for novel solutions to improve quality and productivity of gear manufacturing processes. This study investigates benefits of additive manufacturing technology in gear manufacturing. Machining processes for gear manufacturing such as form cutting, template process or generation process need a groove or extra space for tool output due to its geometry. This is especially a problem in the production of planetary gear reducers. Sun gear input shaft, because of its design, needs groove between the gear and disc on which the planet gears are mounted. This groove is the weakest part of the planetary gear unit and limiting power transfer factor. In this paper we are presenting solution for increasing power transfer in planetary gear reducer by using direct metal laser sintering additive manufacturing technique in producing sun gear input shaft and disc on which the planets are mounted as one part. In this way we have stronger gearbox, while the external dimensions of the reducers are unchanged.
