新型液压机械部件及制造或维修所述部件的方法
摘要：
通过预制衬套(30、40、50)来制造液压机械部件(1)，所述部件至少有部分(14、17、18)遭受到磨损，通过将由陶瓷制实心元件(32)钎焊到金属托座(31、41、51)上预制出所述衬套。其次，通过至少一条焊道(351、352、451、452、551、552)将所述衬套(30、40、50)固定到所述部件的主体(20)上，在所述衬套(30、40、50)和主体(20)之间形成未焊接的根部面(T3、T4、T5)。因此，所制出的新型部件(1)比现有技术的那些部件更易于维修。
摘要（英）：

A hydraulic machine component (1) is produced by pre-fabricating liners (30, 40, 50), at least parts (14, 17, 18) of the component is abraded, the liners are pre-fabricated by brazing ceramic massive elements (32) on metal supports (31, 41, 51). Secondly, the liners (30, 40, 50) are fixed on a single piece main body (20) of the component (1) through at least one seams (351, 352, 451, 452, 551, 552), and unwelded lugs (T3, T4, T5) are formed between the liners (30, 40, 50) and the main body (20), respectively. So that the produced novel component (1) is easier to maintain compared with those components of the prior art.
