... especially pronounced during running-in. Design/methodology/approach Experiments at a twin-disk and gear test rig were combined with chemical, structural and mechanical tribofilm characterization by surface analysis. Pitting lifetime, scuffing load carrying capacity and friction of ground spur gears were...

... calculated by solving the fluid flow governing Reynolds equation using the finite element method, assuming iso-viscous Newtonian fluid. The performance enhancement ratio, which is the ratio of load carrying capacity (LCC) to the coefficient of friction (COF) has been calculated from results to finalized...

... the interior of a rectangle onto the interior of a unit circle, from which the pressure distribution and load carrying capacity are obtained. The calculation results are verified by finite difference method. Findings The constructed Möbius formula is very effective for the performance characteristics...

... 2018 Emerald Publishing Limited Licensed re-use rights only Hydrodynamic lubrication Surface texture Load carrying capacity Pressure distributions Unequal pores h = dimensional local instantaneous gap between surfaces; h₀ = dimensional...

... various sources perform differently because of the difference in the contents of their components. Therefore, the purpose of this study was to investigate the relationships between sulfide components of high-pressure sulfurized isobutylene and load carrying capacities. Design/methodology/approach...

... on bearing surface. The effects of partial groove pattern on the bearing performance parameters, namely, fluid film pressure, load carrying capacity, frictional power loss and frictional torque, are studied in detail. Findings The numerical results show that the values of maximum fluid film pressure...
