Research on Gear Deviation Patterns Based on Rolling Inspection Technology

With the increasing performance demands on gears for new energy vehicles, it has become essential to extract and decouple the gear error information contained in transmission error (TE) and radial composite deviation (RCD). However, a quantitative relationship between TE and RCD has not yet been clearly established. To address this issue, a numerical model of double-flank meshing is developed to reveal their intrinsic relationship. Based on this model, the effects of crowning and pressure-angle deviation on the relationship between TE and RCD are further analyzed.
