... the dynamic film-forming behavior of lubricating grease under steady-state and micro-oscillation conditions. It is found that free water causes a brief rise in the grease film under steady-state conditions, specifically due to the grease-water phase connecting the oil reservoirs on both sides. The experiment...

...Boris Grigor’ev; Artem Eliseev The upper convected Maxwell (UCM) model is one of the ways to describe lubricant’s viscoelasticity. In this paper, a new modified Reynolds equation for the UCM model is derived. This equation may be called extended as compared to its analogs because it incorporates...

...) are the most significant two, followed by Si (silicon content), viscosity, and so on. This is because gears are generally made of steel, once abrasion occurs, naturally there will be more ferromagnetic particles and iron particles in the lubricant. As for Si, we know that impurities in lubricant cause wear...
