Coefficient of friction equation for gears based on a modified Hersey parameter [ J] . Tribology Interna⁃ tional, 2016, 101: 204-217.FERNANDES, C.MCG; MARTINS, R.C; SEABRA, J.H.O, Coefficient of friction equation for gears based on a modified Hersey parameter, Elsevier, 2016....
The magnitude of the frictional force is often directly proportional to the normal force, or the force pressing the two surfaces against each other. The constant of proportionality varies depending on the surfaces which are in contact. For example, you might expect smaller friction when two "slick...
It depends on a parameter α whose range is determined by the coefficient of friction γ, that is, 0⩽α⩽γ. For one extreme value of this parameter, α=0, we recover Kostin's equation. For the other extreme value, α=γ, we obtain an equation in which friction manifests in "...
The equation is given by T2 = T1 * e^(μθ), where T1 is the tension on the side where the rope is initially wrapped, T2 is the tension on the other side, μ is the coefficient of friction between the rope and the capstan, and θ is the total angle of wrap in radians....

In this study, a theoretical formula form of the friction factor containing both viscous and inertial terms is formulated by incorporating the Forchheimer equation, and a new friction factor model is proposed based on a recent phenomenological relation for the Forchheimer coefficient. The viscous term...

Various specific cases have been deduced and the concept of multiple-layer lubrication introduced. The higher lubricant viscosity near the bearing surface is beneficial in reducing the coefficient of friction but the effect of slip is unfavourable....
The Ergun equation systematically underestimates the pressure drop for beds of non-spherical particles. In Eq. (2), the equivalent volume diameter, dp, of a particle of arbitrary shape is defined as the diameter of a sphere having the same volume as the particle: (4)dp=6Vpπ1/3 The ...
