Early railway wagon loaded with tapered roller bearing steel cage

Early railway wagon loaded with tapered roller bearing steel cage - 2020 11 - 05 keep set of rolling bearing with a number of roles, fixed roller and keep an appropriate distance between each other can make the correct rotation, guide roller from load area into the load area and the attenuation of vibration, which requires the cage has enough strength, toughness, wear resistance, corrosion resistance and application of reliability. Bearing cage is traditionally use the metal such as mild steel, aluminium alloy or brass materials by mechanical processing and become, China's early railway wagon loaded with tapered roller bearing cage is by using cold stamping process manufacturing steel cage, in practice, cage booly injury problem is particularly prominent, with the development of high performance engineering plastics, engineering plastics cage has been increasingly used in bearing. China's early railway wagon loaded with tapered roller bearing steel cage, mainly through the stamping die and shearing machine, punching machine, lathe and other equipment keep the low carbon steel processed into frame, its production process generally includes: cutting board, blanking, initial shape, forming, punching, punching hole is, at bottom hole, pressure gradient, expansion, car, light vibration or heat treatment to stress, phosphating, etc. Due to the structure, material, stamping process, the influence of such factors as the steel cage is one-way operation, micro cracks, work stress and the quality problem such as volatility. Shear plate and the noise and greater danger in the stamping production, phosphating process has contaminated industrial waste water and exhaust gas, is not conducive to employee occupational health and safety, also is not conducive to environmental protection. Steel cage in railway wagon bearing applications due to the fracture problems, easy cause hot shaft even eager axis accident risk, has been to improve reliability and safety of bearings, with good processability and self lubrication, larger toughness and elasticity, low friction wear of engineering plastic cage. （ Source: the resources of railway vehicle platform)
