Anyone can guide me how to design gearbox on speed reducer?(adsbygoogle = window.adsbygoogle || []).push({});

If I using spur gear on my design which type of spur gear has better lifetime and lower cost?

1) Brass Spur Gears

2) Steel Spur Gears

3) Stainless Steel Spur Gears

4) Ground Spur Gears

If Steady-state input speed 1000 rpm and Steady-state output speed 180 rpm so

1000/180 = 50/9 by factor this ratio I get 2:1 and 25/9:1

For my N2/N1 is better use ratio 2:1 or 25/9:1 ?
