A steel spur pinion has a pitch of 6 teeth/in, 22 tooth full-depth teeth with a cut profile, and a 20 pressure angle. The pinion runs at a speed of 1,160 rev/min and transmits 17.434 hp to a 60 tooth gear. of the face width is 2 in., estimate the static bending bending stress in the gear ooth in psi. Use the Lewis equation. Take the value of Lewis form factor, Y, from the table 14-2. Note do NOT use the elocity factor Kv in the bending stress equation.

A gear drive is required to transmit a maximum power of 22.5KW, the velocity ratio is 1:2 and the rpm of the pinion is 200 .the approximate center distance between the shaft may be taken as 600mm.the teeth has 20°stub involute profile.the static stress for the gear material ( which is cast iron ) may be taken as 60MPa and face width as 10 times the module.find the module, face width and number of teeth on each gear.Check the design for dynamic and wear loads. The deformation factor in the buckling equation may be taken as 80 and material combination factor for the wear as 1.4

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?

In a gear set, a 36-tooth spur pinion drives a 60-tooth spur gear. The teeth of these gear are cast iron profile. The diametral pitch is 6-teeth/in, the face width si 0.5 inches, and the pressure angle is 20 degrees. Assume that the pinion transmits 10 hp at a speed of 2000 rpm. Find the tangential load in lbf Find the contact stress in kpsi, assuming CP=1960 psi.
