Ceramic Medical Instruments as an important mechanical foundation pieces, because of its metal bearings can not match the excellent performance, high temperature, super strength in the world of new materials dominate. Over the past decade, in the national economy and people in various fields has been increasingly widely used.
Aerospace, marine, nuclear industry, petroleum, chemical industry, machinery, metallurgy, electric power, food, locomotive, subway, high-speed machine tools and scientific research military and other fields need high temperature, high speed, deep cold, flammable, easy Explosion, strong corrosion, vacuum, electrical insulation, non-magnetic, dry friction and other special conditions of work, Ceramic Medical Instruments indispensable alternative role is being gradually recognized.
Over the past decade, Ceramic Medical Instruments in the national economy and people in various fields has been increasingly widely used. Here to introduce the advantages of Ceramic Medical Instruments:
First, because the elastic modulus of the ceramic than steel, stress is not easy to deformation, it is conducive to improve the working speed, and to achieve high accuracy.
Second, because the ceramic is almost not afraid of corrosion, so the ceramic rolling bearings suitable for corrosive media in the harsh conditions of operation.
Third, the impact of thermal expansion and contraction of the ceramic than the steel is small, and thus a certain gap in the bearing, the bearing can be allowed to change the temperature changes in the more intense environment.
Fourth, because the ceramic rolling ball density is lower than the steel, the weight is much lighter, so the rotation of the outer ring when the centrifugal effect can be reduced by 40%, and thus greatly extend the service life.
In summary, due to the Ceramic Medical Instruments in the application of so many advantages, so the major manufacturers of imported bearings such as: SKF bearings, NSK bearings, FAG bearings are related to this area and the introduction of the corresponding products.
With the continuous improvement of processing technology, the increasing level of technology, Ceramic Medical Instruments continue to decline in the cost of the past has only in some high, refined, sharp areas of small applications, and gradually extended to the various sectors of the national economy, product market prices But also gradually close to the practical, to the user acceptable level, a large area of Ceramic Medical Instruments wave application has come.
Ceramic ball bearings for the defense industry in the harsh environment of the adjustment, heavy load, low temperature, no lubrication conditions and development, new materials, new technology, the perfect combination of the new structure. Will be converted into civilian technology, ceramic ball bearings can completely cover the current precision, more than the full range of all steel bearings in all applications. Ceramic Medical Instruments diameter, diameter and other dimensions are the country to develop steel bearings P4, P5, P6 standard size. Due to the low coefficient of thermal expansion of ceramic materials, small heat transfer performance, small elasticity and other characteristics, the installation and cooperation need to be noted.
Ceramic bearing performance and price ratio is far superior to all steel bearings, life than the current use of bearing life increased more than 3 times, can save a lot of downtime maintenance time, reduce the rejection rate, reduce the stock bearing spare parts. The same time as
Compared with the bearing steel performance, the weight is 30% -40% of the bearing steel, can reduce the centrifugal force generated by the increase in moving load and slip. Due to high wear resistance, the speed is 1.3-1.5 times the bearing steel, can reduce the high-speed rotation of the channel surface damage. The modulus of elasticity is 1.5 times higher than that of bearing steel. The elasticity of the force is small, and the deformation due to the high load can be reduced. Hardness is 1 times the bearing steel, can reduce wear. Compression is 5-7 times the bearing steel. The coefficient of thermal expansion is less than 20% of the bearing steel. The friction coefficient is less than 30% of the bearing steel, can reduce the heat generated by the friction, can reduce the high temperature caused by the early peeling off the bearing failure. Tensile, bending and metal equivalent. Imported bearings
Ceramic Medical Instruments with high temperature, cold, wear, corrosion resistance, anti-magnetic insulation, no oil self-lubricating, high speed and other characteristics. It can be widely used in the fields of aviation, aerospace, navigation, petroleum, chemical, automobile, electronic equipment, metallurgy, electric power, textile, pump, medical device, scientific research and national defense and military fields. New materials used in high-tech products. Ceramic bearing rings and rolling body using all-ceramic materials, zirconium oxide (ZrO2), silicon nitride (SisN4), silicon carbide (Sic) three. The holder is made of polytetrafluoroethylene, nylon 66, polyether imide, zirconia, silicon nitride, stainless steel or special aviation aluminum, thus expanding the application of Ceramic Medical Instruments. Applications: medical equipment, low temperature engineering, optical instruments, high-speed machine tools, high-speed motors, printing machinery, food processing machinery.
