What it covers

  • Gear macrogeometry and ISO 6336:2019 rating: load factors, pitting, tooth root strength and duty cycles
  • Microgeometry, transmission error, gear noise and rattle
  • Shafts and rolling bearings
  • A step-by-step KISSsoft sizing workflow with loaded tooth contact analysis
  • AI-driven optimisation with genetic algorithms and NSGA-II, run from MATLAB
