捷变磁控管是捷变频雷达的心脏部件,而高温高真空白润滑轴承又是机械调谐捷变频磁控管的关键部件。这类轴承的使用指标是:温度400—450℃;真空度10~(-6)—10~(-1)乇;转速3000—4500rpm/s;轴向负荷不大于1kg;寿命340h。基于上述要求,我所提出了采用自润滑保持架转移润滑法和滚球振动涂膜法的综合技术路线,设计了一种三元体系自润滑保持架材料,经上海微型轴承厂加工并组装交有关单位进行装管试验。在10cm和20cm磁控管中全方位满功率条件下运转寿命都超过600h。并且
The agile magnetron is the heart of the agile frequency radar, while the high-temperature, high-vacuum white-lubricated bearing is a key component of the mechanically tuned agile frequency magnetron. The use of such indicators are: temperature 400-450 ℃; degree of vacuum 10 -6 (-6) -10 -1 Torr; speed 3000-4500rpm / s; axial load of not more than 1kg; life 340h. Based on the above requirements, I proposed a self-lubricating cage transfer lubrication method and rolling ball vibration coating line of the integrated technology to design a ternary system self-lubricating cage material, the Shanghai Micro Bearing Factory processing and assembly to pay Relevant units to carry out test tube. In 10cm and 20cm magnetron all-round full-power operating conditions are more than 600h. and
