Targeting an accurate and realistic simulation of the gear hobbing process, we present an effective and factual approximation based on three-dimensional computer-aided design. Hobbing kinematics is directly applied in one gear gap. Each generating position formulates a spatial surface path which bounds its penetrating volume into the workpiece. The three-dimensional surface paths generated from...

This paper presents an integrated design of a drivetrain for a single-person ultra-light electric vehicle (ULEV). To calculate losses and efficiency of the inverter, the permanent magnet synchronous machines (PMSMs) and the gearbox, parameterised analytical models are used. For the gearbox – which has a single gear ratio – the studied parameters are the gear ratio, the number of stages, the num...

The aim of this study is to evaluate the effect of super finishing on gear acceleration and noise level. Many researchers [1-13] have studied the gear dynamic models to study the effect of various parameters on gear dynamics. A 6DOF model is developed and experimental studies were conducted. In this study, the effects of super finishing [14, 15] on gear acceleration and noise level were evaluat...
