【摘要】 本文作者针对航空、航天柱塞式液压泵轴封在动态下易发生"粘铜"故障和在静态下漏油故障突出的问题,研制出两种新型轴封材料,即承载力大、抗干磨的含钠米粒子烧结青铜自润滑复合材料及易磨合的烧结青铜减摩材料,并在泵上获得应用。同时,在不改变航天泵轴封结构尺寸和兼顾动、静态密封性能的条件下,研究了密封副材料配对、磨合工艺、磨合图像及表面激光造型等因素对静态密封泄漏量的影响。更多还原

【Abstract】 In accordance with the seal fails in adhesive wear and leakage occurred for rotary shaft seals of aviation & space hydraulic pumps the authors have developed two new types of material that have been used on the pumps , i.e. one type of dry-wear resistant sintering compound material containing nanoparticals ,and another antifriction bronze sintering alloy . At the same time ,under existing conditions the influences of the factors including material pairs, wear-in processes, wear-in pictures, laser surface texturing on leakage amount of shaft seal under static state have been studied.更多还原
