(OP)
Given a speed ratio, which gearbox has better efficiency step up or step down ? For example, of 990/850 RPM or 720/850 RPM, which gear ratio will have lower losses ?





RE: Speed Increaser or Decreaser, which is better
I doubt that there is a significant difference in the efficiency of spur or helical gears, or chain or belt drives for that matter. I would be much more interested in the efficiency of your motor. Does it provide the required power more efficiently at 990 or 720 RPM?
