The oil film bearing housing is a radial sliding bearing seat with lubricating oil as the lubricating medium; its mission principle is: in the rolling process; because of the rolling force effect; forcing the roller shaft journal to move; the oil film bearing seat center of gravity The center of gravity of the journal is fair; the gap between the oil film bearing housing and the journal forms two regions; one is called the diverging zone (the gap becomes larger along the direction of the journal rotation); the other is the convergence zone (along the journal) The direction of rotation is gradually reduced. When the rotating journal brings the viscosity of the lubricating oil from the divergent zone into the convergence zone; the gap of the bearing seat changes greatly along the direction of the journal rotation. The resultant force of the pressure in each direction of the oil film along the rolling direction is the bearing capacity of the oil film bearing seat. When the rolling force is greater than the bearing capacity; the fair distance between the center of gravity of the journal and the center of gravity of the oil film bearing seat increases. The gap of the bearing housing becomes steep along the direction of rotation of the journal; the minimum oil film thickness becomes 湍つ诘 湍つ诘 沽Ρ浯螅 沽Ρ浯螅 亓Ρ浯螅 亓Ρ浯螅 Φ Φ Φ Φ Φ Φ Φ Φ Φ Φ Φ Φ Φ Φ Φ The fierce shackles are still smashing through the scorpion.
From the mission principle of the oil film bearing housing, one of the most important parameters in the triangulation of the oil film bearing housing is the minimum oil film thickness.
