Electrochemistry is rotten caused by sliding tail bearing, however due to the corrosivity of aqueous medium especially seawater, and electric conductivity by aqueous medium
Erosion makes the very serious larger abrasion of simultaneous of metal erosion phenomenon of tail bearing.
Iron is ploughed wood material and is just applied on stern journal bearing of ship since in the middle of the 19th century, by the study found that resin, resin
Refined juice, animi resin and bitterness refined juice, the self-lubricating property of iron plough wood material and the conversion of resin and refined juice are closely related, on the one hand
The resin being housed in gap is extruded gap and enters between the secondary contact surface of two frictions under the effect of external force, in frictional heat
Be precipitated lubricating oil under the collective effect of shear action, and gradually form one layer of oil film, the reinforcing of the oil film of formation in the region
To cooling situation of the mill between secondary, reduce the fretting wear between secondary to mill.Essence contained in another aspect iron plough wood
Juice, which meets water, can form lotion, and the formation of lotion enhances the bearing capacity of material, reduce the frictional heat between secondary to mill, to
Ensure the stabilization of the wooden tail bearing of iron plough.However iron plough wood material quality is softer, the not strong defect of anti-silt performance also limits iron
Plough the application and development of wood material.
Under low speed, heavy duty and the bad operating mode of lubricating condition, there is iron plough wood material unique structure can give tailing axle
The effective improvement lubricating condition of offer is provided, lowers the abrasion of storeroom, however iron ploughs its wooden scarcity of resources, sediment environment adaptability
Simultaneously, as that studies tail bearing gos deep into, more and more materials are applied among this field of water lubrication tail bearing difference,
High polymer is exactly one of them.High polymer material has good wearability, under high-revolving operating mode, can be formed effective
Moisture film so that material possesses lower friction coefficient, but under low speed or the operating mode of heavy duty, since moisture film is established not exclusively,
Bearing capacity is low, and cooling condition is bad so that the fretting wear of material is more serious.By material and high score with greasy property
Sub- polymer carries out the method that blending and modifying is relatively conventional, however the compatibility difference between different materials is very big, composite material
It is susceptible to and mutually divides, additive is easy leakage, and the lubricant of filling is difficult to play lubrication anti-attrition under extreme operating condition.
The bionical microcapsules for being currently used for tail bearing are few, and wherein CN2016104587184 discloses a kind of bionical micro- glue
Capsule self-lubricating composite and preparation method thereof.It synthesizes microcapsules by the method for phase separation, and the core material of microcapsules is more
Fat is originated, however the synthetic method combined coefficient being separated is low, synthesized microcapsule structure stability is general.
