The lubricant can form a tough lubricating film when applied on the surface of a metal.
The lubricating film hence has improved wearing resistance.
An elastomeric gasket (28) for a pipe coupling having a dry lubricating film (29) of an aqueous solution of a lubricant and a film-forming polymer adhered thereto.
Also provided is a method for preparing the composite sulfide solid lubricating film.
The thickness of the lubricating film establishes the level of friction.
A sliding bearing comprising an axial bearing part (6) with grooves (9) is useful for forming a hydrodynamic film of lubricant.
After the formation of lubricant film (33), wiping treatment is carried out on the surface of the lubricant film (33).
The high-viscosity lubricant and the low- viscosity lubricant are drawn into the clearance space by hydrodynamic action to form a bi-component lubricant film.
A lubricant film is provided in the contacts between the rolling elements and the raceways, which film forms a lubricant meniscus at the inlet side of each contact.
By this wiping treatment, any particles adhering to the surface of the lubricant film (33) are entwined away.
This meniscus displacement results in an increased lubricant film thickness in each contact area, thus improving the lubricating conditions in the bearing.
The rotors (22) are held in position by water lubricated fluid film journal and thrust bearings.
Having radially oriented oil grooves with suitable width enables adequate oil supply and improved hydrodynamic oil film generating capability.
Because there isn't leakage passage in the gas ring, gas-tight and oil control ability is good, the shortage of heating piston and destroying oil film is eliminated.
The process includes a step in which a ductile metal part is over-coated with either the liquid-film or solidfilm lubricant.
Investigation of the form and thickness of lubrication films
Boundary Lubrication - Lubrication between two rubbing surfaces without the development of a full fluid lubricating film.
A form of lubrication between two rubbing surfaces without development of a full-fluid lubricating film.
The hydraulic oil provides a constant lubricating film to all moving components.
They are extremely thin and sharp and are coated with a lubricating film.
The lubricating film (5) exhibits a favorable lubricating property and generates little dust, and the particles (6) mixed in the film provide a favorable cushioning action under loading.
The surface of the bolt is surrounded by a lubricating film, and at least one essentially axial bore hole and a plurality of radial bore holes (13,14,15) leading to the surface of the bolt are provided for supplying the lubricant.
In order to create sufficient lubricating film, the lubricant must maintain a certain minimal viscosity at operating temperature.
In order to create sufficient lubricating film, the lubricant must maintain a certain minimal viscosity at operating temperature.
A fluid outlet arrangement (48,148) from the cavity delivers lubricating fluid to the flow path to form a downstream lubricating film about viscous fluid flowing therein.
κ = 4 indicates a regimen for which the rolling contact load is carried by the lubricant film – i.e. full film lubrication.
The invention relates to a method for determining the thickness of a lubrication film (5, 15) in a bearing by measuring a capacitance (C).
As the lubricating film (5) itself and the particles (6) are fluorine based, they provide for a good compatibility therebetween.
The lubricant film developed between moving metal surfaces in contact simply does not allow this contact.
