A pair of helical gears consist of 25 teeth pinion gear meshing with a 90 teeth gear. Calculate the wear strength If surface hardness is 260BHN. Also face width=35mm, module=4mm and helix angle=25⁰.
(a) 443.5N
(b) 1125.6N
(c) 7971.9N
(d) 1014.2N
I got this question in previous year papers.
I am preparing the Rolling Contact Bearings, Spur Gears and Helical Gears section in section Rolling Contact Bearings, Spur Gears and Helical Gears of Machine Design
