Q2+ State advkatages of Cycloidal In volute profile as a gear tooth prfie.
A parallel shaft helical gear consists of a 20 dts drive pinion And a 96 driven gear. Both gears have a transverse diametrical pitch of 20 dts / in, a helix angle of 25 and a pressure angle on = 20 . The face width is 4 in., AND the gears are moving at 1600 ft / min, on the pitch line. The impeller is made of steel UNSG 10180 CD and without heat treatment; the driven one is made of grade 30 cast iron. Based on flexural strength calculations, evaluate the capacity or safe maximum power at hp. Consider general industrial service, and nG = 4.
