Engineering plastic cage properties

Engineering plastic cage properties - 2018 11 - 30 ( Railway vehicle resource platform) Cage is used in the railway vehicle with the important parts in the rolling bearing, its safety is the first requirement, engineering plastics not only need to have a certain strength, and also has higher requirements for toughness, only Gao Qiangzeng toughening composites can meet the requirements of the design of the cage, development at home and abroad at present mainly use nylon alloy type of engineering plastics. Nylon alloy plastics because of its excellent performance has become a widely used engineering plastics, a large number of used in machinery, automobiles, electrical appliances, textile, chemical, aerospace, metallurgy, etc. The main performance is as follows: 1, the excellent mechanical properties, nylon high mechanical strength, good toughness; 2, good self-lubricating, frictional resistance, nylon has the very good self-lubrication, low friction coefficient, it can be used as the driving part, and long service life; 3, good heat resistance, thermal deformation temperature is higher, nylon engineering plastics after glass fiber reinforced modified, its temperature range can be greatly improved; 4, good oil resistance, can withstand all kinds of petrol, engine oil, gear oil, brake oil, and lubricating oil; 5, excellent electrical insulation properties, high volume resistance, corrosion resistance, high breakdown voltage is a good electrical, electrical insulation materials; 6, excellent weatherability; Research shows that, compared with other plastic, modified nylon is more suitable for manufacturing the bearing cage. Engineering plastic cage than traditional metal cage has the following advantages: light weight, self-lubricating, low noise, low cost, high strength, impact resistance, abrasion resistance, especially lack of oil in a state of emergency security outstanding advantages, such as, is a good way to replace metal cage.
