With Electric Vehicles (EV), gear noise reduction is critically important. Gleason’s GMS® Inspection Systems apply multiple analysis tools to help identify the root cause of gear noise. These include Fourier analysis, Tooth Contact Analysis, Surface Finish Analysis, Kinematic Transmission Error Prediction Software (KTEPS) and Advanced Waviness Analysis. The GMSL and GRSL systems offer the added benefit of laser technology for full flank form inspection at ultra-fast speeds.
