Split the sliding bearing lubrication principle

Split sliding bearing is also called the open sliding bearing, the bearing, bearing, split bearings, gaskets, bolts, etc, to understand the form structure, bearing lubrication principle and installation process, the maintenance of large equipment, maintenance is an important work. Split sliding bearing lubrication principle 1 lubrication principle of this kind of bearing lubrication form roughly three process, shaft resting in the lowest position due to its own weight, and lubricating oil is journal extrusion, thin wall bearing and shaft neck side wedge formed between clearance, when the shaft neck rotation, due to the oil viscosity in the metal surface adhesion, reservoir with the axis of rotation, reservoir through the wedge clearance due to molecular kinetic energy squeeze and itself, the upward pressure will shaft, the shaft of the when reaches a certain speed, pressure oil on the shaft, shaft and bearing surface completely separated by a film, to form the liquid dynamic pressure lubrication. Split the sliding bearing lubrication principle form liquid dynamic pressure lubrication condition is: (1) after the journal and bearing with should have a certain gap, general is equal to 1/1000 ~ 3/1000 of the diameter of the neck; (2) the journal must have certain linear velocity to build enough oil wedge pressure; (3) between the two working face must be continuous with certain viscosity lubricating oil. The previous: internal lubrication technology to solve bearing heating next up: none
