Optimizing the geometric design of a helical gear through simulation and surface roughness measurement analysis

, 2023
In order to elevate the helical gears’ performance, durability, and reduce teeth regarding failures, this study measures the parameters from the non-functional fractured helical gear model and modifies them in order to construct a highly efficient ...
