Water-Lubricated Soft-Rubber Bearings

Journal of Fluids Engineering, 1932
Abstract Rubber bearings lubricated with water are found to have remarkably low coefficients of friction and to give excellent service under many conditions. The softness of the rubber makes these bearings stand up in the presence of sand and grit, and it also makes the laws of lubrication governing these bearings differ from the ...

STUDY ON TRIBOLOGICAL BEHAVIOR OF WATER-LUBRICATED BEARINGS

Journal of Advanced Manufacturing Systems, 2008
Water-lubricated compound rubber bearings make use of new engineering complex material to replace precious metal as frictional pairs, and natural water to replace mineral oil as lubricant. They enable energy conservation and are environmental friendly and can be widely applied in many engineering fields such as shipping, machinery, petroleum industry,

Water lubrication of phenolic bearings

Scientific Lubrication, 1949
PHENOLIC bearings have frequently been used P for roll mills, thrust collars and rings, lifter bearings, side bearings on brass mills, plate mills and sheet mills, etc. They have sometimes replaced lignum vitae for marine propellor shaft bearings. Their lubrication can be effectively accomplished with water which, obviously, is the best coolant.

WATER‐LUBRICATED BEARINGS FOR MARINE USE

Journal of the American Society for Naval Engineers, 1958
The properties of water as a lubricant are discussed and the problems of practical hydrodynamic lubrication with water are shown to be capable of solution. From this basis, two general marine bearing applications are considered, the first involving large relatively low-speed bearings, and the second smaller high-speed bearings.

Characteristics and Outline of Water-Lubricated Thordon Bearing

Advanced Materials Research, 2012
Thordon is a new liner material used widely in water-lubricated bearings in virtue of its shockproof characteristic, high load and wear resistance. The category of materials used in water-lubricated bearings was briefly outlined and tribological characteristics of most of the materials were compared in the paper.

Rotor Rolling over a Water-Lubricated Bearing

Thermal Engineering, 2018
The article presents the results of studying the effect of forces associated with secondary damping coefficients (gyroscopic forces) on the development of asynchronous rolling of the rotor over a water-lubricated bearing. The damping forces act against the background of other exciting forces in the rotor–supports system, in particular, the exciting ...
