Question #222817
The following data is given for a pair of helical gears made of steel. Normal module = 5 mm, Face
width = 50 mm, Number of pinion teeth = 30, Number of gear teeth = 60, Centre distance = 245 mm,
Normal pressure angle = 20⁰, Pinion speed = 1000 rpm, Permissible bending stress for pinion and gear
material = 150 N/mm2
, Surface hardness = 300 BHN, Factor of safety = 2.0, Service factor = 1.5, Grade
of machining =8. Determine: -
