Reliability Assessment of Gear.
From above data the material strength of gear are δ(μδ, σδ), and the stress are s(μs, σs), then the reliability of the gear is: where: μδ,= 360, mean of the strength of gear σδ = 18, standard deviation of the strength of gear μs = 280, mean of the stress of gear σs= 20, standard deviation of the stress of gear then the reliability of the gear is: R = P(δ>s) where: R is gear reliability δ is stochastic variable of strength s is stochastic variable of stress Because both strength variable and stress variable are normal distribution variables, R can be obtain through bellow formulas.
