Process of designing spatial biplanetary gear

Abstract

W niniejszym artykule przedstawiono proces projektowania przestrzennej przekładni biplanetarnej z kołami zębatymi stożkowymi. Dodatkowo szczegółowo omówiono sposób wyznaczania najważniejszego parametru kinematycznego każdej przekładni, tj. przełożenia kinematycznego.This article discusses the process of designing complex spatial biplanetary gear, also known as double planetary gear units with bevel gear wheels. Particular attention was paid to the most important and most difficult part of this process, i.e. the calculation of the kinematic transmission ratio. The important role of sketches already created in the early stage of design process was also emphasized. These sketches, in particular when made in 3D, allow early detection of collision points between adjacent gear elements and unfinished nodes of the structure of the projected gear. Also assembled drawings and assemblies made in 3D allow not only detailed study of the complex biplanetary gearbox, as they facilitate the complex assembly and disassembly processes. Also, they can also detect any possible collision of transmission components
