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.

There is a motor with a power of 38 HP. The driving pinion has a speed of 20 rpm and the driven pinion of 5 rpm. Design the driving pinion and driven pinion based on the rpm of each pinion. do not forget the module and the number of teeth for each pinion. Gear ratio value: i= 5 rpm / 20 rpm = 0.25
A 35 kW motor running at 1200 rpm drives a compressor at 780 rpm. The arrangement is made through a 90° bevel gearing arrangement. The pressure angle of teeth is 14.5°. The allowable static stress for both pinion and gear are 85 MPa. Determine the number of teeth on the gear, face width, addendum, dedendum, outside diameter and slant height, thickness of tooth. Also check your design from the standpoint of wear. Take surface endurance limit as 690 MPa and modulus of elasticity as 89 kN/mm2.
A steel spur pinion and gear have a diametral pitch of 13 teeth/in, milled teeth, 19 and 34 teeth, respectively, a 20- pressure angle, and a pinion speed of 540 rev/min. The tooth properties are Sut = 76 kpsi, Sy = 42 kpsi and the Brinell hardness is 149. For a design factor of 2.25, a face width of 7/ 8 in, what is the power rating of the gearset?

Please prove the answers 4 and 5 , the answers are already given as Ta, Tc, Td, Wt, Wr written in bold letters in the pic for problem 4 and for problem 5, D
A spur gear reducer is to transmit 4 kW at 1500 rpm of the pinion of cast steel ( So=138 MPa). The gear is made from phosphor bronze (So=83 MPa). The velocity ratio is 3.5 to 1.0. Assume a pressure angle of 20°. Design the gears for strength only.
