Following the progress of the imported bearing speed; the high-density metal data is not satisfactory for the bearing; the density is only 1/4 to 1/8 of the metal; it is wear-resistant, shock-resistant, diamagnetic, radiation-resistant, corrosion-resistant, low Plastics with common strengths such as conflicts; entering the team of rolling bearing support materials. Phenolic laminated cloth has low density, high mechanical strength, good mechanical processing function, certain heat-resistant temperature and oil absorption, oil seepage and other functions; Widely applied to the support frame of angular touch ball bearings with inner diameter of 2~200mm. For example, high-speed grinding head bearings, machine tool bearings, external bearings, gyroscope bearings, turbine bearings, supercharger bearings, etc. all use phenolic laminated cloth to support the frame; The dn value can be as high as 12Ã—106mm r/min.
Where the metal support frame is not satisfactory to the host's needs; the plastic support frame shows special advantages, such as bearings that do not allow the use of smooth oil liquid oxygen (-183 Â° C); with a stamped steel frame Deep groove ball bearing 6204 is burned in 100kg axial load; 10000r/min for 16min; and glass fiber reinforced PTFE plastic is used to make the angular contact ball bearing of the frame; the axial load at 100kg; 20000r/ After working for 20 hours at min; the conflicting moment is still not added. The polyimide modified with molybdenum disulfide, polytetrafluoroethylene and glass fiber is used as the bearing holder; it can be operated without oil under vacuum radiation; it has been applied to Abo Luo Fei ship. Porous oil-containing polyimide adheres to the long-life bearing of the gyroscope; the porous oil-containing phenolic laminated cloth adheres to the bearing of the communication satellite organization; the polyimide adheres to the high-speed dental drill bearing; Glass fiber reinforced polyamide 66 adheres to the gearbox, differential gearbox, clutch and hub of the car, water pump and mine conveying equipment; the application is very outstanding.
