Property is bad, influences bearing running precision；There are also a kind of engineering plastics and the two layers of composite material of metallic matrix through hot press molding
Water lubriucated bearing, the type bearing have self-lubricating property but also with good mechanical strength, but when bearing diameter is larger,
Hot press forming technology is more complex, and manufacturing cost is high；Existing patent ZL200410100476.9 " water labricating metal plastic bush and life
Production method ", be molded using engineering plastics and porous metals silk pad, be sintered to form certain thickness composite material, then with it is stainless
Steel matrix is brazed manufactured 3-layer composite material water lubriucated bearing, and bearings synthesis performance is relatively good.The airframe bearing housing if you need to
Anti-corrosion and when using stainless steel, stainless steel welded face need to usually be carried out to specially treated, such as surface plating iron, but iron layer is plated and soak for a long time
Perishable the shortcomings that getting rusty in water, and the more complex high production cost of manufacturing process.The water lubriucated bearing of the above different structure, all
There are different problems.
