    • A bearing arrangement for a gear pump comprises first and second separate bearing blocks each having a respective block housing. The first and second bearing blocks together defining an axially directed bearing surface including a bridge region formed from an erosion resistant material which acts to separate inlet and outlet ports of the pump and a second region formed from a reduced friction material. The bridge region is defined by first and second insert members cast within respective ones of the block housings. The first and second bearing blocks are arranged such that respective surfaces of the first and second insert members mate with one another, and the first and second insert members are arranged such that the bridge region of the bearing surface is flush with the second region.
    • 用于齿轮泵的轴承装置包括第一和第二分离的轴承座,每个轴承座具有相应的车厢外壳。 所述第一和第二轴承座一起限定轴向定向的支承表面,所述轴承表面包括由抗侵蚀材料形成的桥接区域,所述桥接区域用于分离所述泵的入口和出口以及由减摩擦材料形成的第二区域。 桥接区由第一和第二插入构件限定,该第一和第二插入构件在相应的块体外壳内铸造。 第一和第二轴承座布置成使得第一和第二插入件的相应表面彼此配合,并且第一和第二插入构件布置成使得支承表面的桥接区域与第二区域齐平。
