The drawback(s) of the classic Lewis equation to find bending stress in gear a tooth are:
The tooth load in practice is not static.
The whole load is carried by single tooth is not correct.
The greatest force exerted at the tip of the tooth is not true
All of these options
Which of the following design factor (suggested by AGMA) depends on the tooth profile inaccuracies?
AGMA Geometry factor (J)
Load Distribution Factor (Km)
Dynamic Factor (K,)
If the number of fatigue is smaller than the number of yield, would that be safe or not? and why? (In shaft)

- How can the average shear stress be related to the torque?arrow_forwardAnother very common mode of failure of gear teeth is that due to surface damage or pitting, which can eventually result in extensive cratering and loss of the load bearing surface of the tooth. Which of the following best describes the causes, and some of the measures that can be taken to prevent this form of failure. a. Maximum compressive stresses occur at the root of the tooth; - Stress concentrations due to cracks in the tooth flank can increase these stresses; - Failure is due to fatigue loading, and is worse because of shock loads: -Asperity to asperity contact, and hence high surface roughness or poor lubrication can make this failure worse; - Surface load capacity can be improved by selecting materials with high surface hardness values, such as carburised steels; - Once pitting has occurred over more than 10 % of the surface, gears are no longer serviceable. b. Maximum tensile stresses occur at the point of contact between the teeth; - Stress concentrations due to pits or small…arrow_forwardIn gear designs, geometric numbers, I and J will be needed to calculate bending and contact stress numbers per per AGMA standards. Please select all the answers that apply. Geometry factor I will be different for the pinion and for the gear. Geometry factor J will be the same value for both the pinion and for the gear. Geometry factor J will be the different for the pinion and for the gear. Geometry factor I will be the same value for both the pinion and for the gear.arrow_forward
