Ceramic Medical Instruments 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 Medical Instruments can completely cover the current precision, more than all the steel bearings in the application area. Ceramic Medical Instruments diameter, diameter and other dimensions are the country to develop steel bearings P4, P5, P6 standard size. Due to the low thermal expansion coefficient of ceramic materials, small heat transfer performance, small elasticity and so on, 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 the above-
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 and tear. Compression is 5-7 times the bearing steel. Thermal expansion coefficient is less than 20% of bearing steel. The friction coefficient is less than 30% of the bearing steel, can reduce the heat generated by the friction, can reduce the bearing caused by high temperature off before the failure. Tensile, bending and metal equivalent. Imported bearings
First, because the ceramic is almost not afraid of corrosion, so the ceramic rolling bearings suitable for corrosive media in the harsh conditions of operation. The same time as the above-
Second, 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. The same time as the above-
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 in the more drastic environment. The same time as the above-
Fourth, because the ceramic elastic modulus than steel, stress is not easy to deformation, it is conducive to improve the working speed, and to achieve high accuracy.
