Q4 An uncrowned straight-bevel pinion has 22 teeth, a module of 4.5 mm, and a transmission accuracy number of 8. The pinion is made of Nitralloy 135 M Grade 2 steel having core and case hardnesses of Brinell of 224. The gear is made of carburized and case hardened Grade 1 steel, both having core and case hardnesses of 280 Brinell The pinion drives the 28-tooth bevel gear. The shaft angle is 90°, the pinion speed is 1524 rev/min, the face width is 36 mm, and the normal pressure angle is 20°. Both gears have an outboard mounting. Find the power rating based on AGMA bending and pitting resistance if the life goal is 109 revolutions of the pinion at 0.9999 reliability.Use Ko = 1.25; SF = 2 and SH = 1.5.

Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.
