Website bearing bushing product material and application features

Website bearing bushing material products and application characteristics of the bearing bushing movable part of a large number of applied to aircraft, also often used in helicopter rotor shaft and the aircraft landing gear, etc. Beauty bud is the group in its circle and flange surface USES the independent research and development of teflon material, thus achieved without the use of traditional lubrication conditions. Bearing bush to use material, need to determine according to the practical application. If it is low load with no steel base metal plastic bushing, if the high load of steel base iron with a plastic liner. Sliding bearing is used in antifriction material of shaft sleeve and bearing bushing, bushing. Usually cast within the bearing surface, mainly in order to reduce costs, save precious antifriction materials. The thickness of 0. 5 - 6 mm, for big size or important bearing. Bearing bushing material: 1. Modified ptfe ( PTFE） Lead ( Pb ） And other filling mixture 0. 01 ~ 0. 3 mm, a kind of wear-resisting material, operating process to form transfer film to protect the grinding shaft. 2. Copper powder layer 0. 2 to 0. 3 mm increase PTFE/Pb with steel plate bonding strength, has the very good bearing capacity and abrasion resistance. Copper is a kind of very good thermal conductive materials and quick heat transfer occurring in the process of bearing operation. 3. Low carbon 0. 7 - 2. 3 mm, improve bearing capacity and the heat transfer effect. 4. Copper/tin plating, copper plating 0. 008 mm, tin plating 0. 005 mm, the bearing has good corrosion resistant function. Bearing bushing application features: 1. In a small friction coefficient and stable oil lubrication conditions. 2. Good wear resistance, impact resistant performance is good. 3. Under the condition of fluid lubrication PV value of up to 120 n/was m. / s4. Bearing bushing at present the product has been widely applied in all kinds of gear oil pump, plunger pump, vane pump, etc, on condition of fluid lubrication or boundary lubrication of high pressure gear pump are used.
