Bequeath life to death: State-of-art review on three stage helical gearbox

Several research papers available in notable publications have been dedicated to different stages of helical gearbox. However, most of the previous investigation was focused on single stage and double stage helical gearboxes, while only a few studies covered triple stage helical gearboxes even though it has numerous advantages. Recently, the significance of three stage helical gearboxes has received a lot of attention among various research professionals associated in this area. In this study, comprehensive assessment was conducted on the current three stage helical gearbox literatures for examining most currently used distinct research designs, methods, tools & techniques, enablers & barriers and also identifying diverse research inclinations, major findings, shortcomings and suggesting the potential directions in futuristic research. This exploration perilously investigated 275 research papers on various stages of helical gearbox and conducted a structured literature review of 28 articles on three stage helical gearboxes published in various journals over the last two decades using content analysis methodology with inductive research approach. The major findings shows that there are immense potential for dominating the research field and several opportunities still exists for three stage helical gearboxes development, which in turn open up new avenues for experts and industries.
