齿轮的翻转运用齿轮泵齿轮磨损首要是在齿厚部位，而齿轮端面和齿顶的磨损都相对较轻。齿轮在齿厚部位都是单侧磨损，所以可将齿轮翻转180度运用。当齿轮端面磨损时，可将端面磨平，还研磨润滑油泵壳体连系面，以包管齿轮端面与泵盖的空地在标准限制内。布赫齿轮泵的检修步骤：拆开拆开前应做好充分的准备工作。
熟悉设备结构，工艺流程，运转状态;拆开时应小心翼翼，避免损坏设备零部件。复查数据对齿轮泵各部件配合空隙，应做全面查看，部分空隙的标准见表。查看对拆下的零部件进行具体查看，对齿轮作上色查看，不答应存在裂纹;轴颈的圆锥度合格，表面不得有划痕，粗糙度Ra的大答应值为1.6μm;端盖、托架、泵体不得有明显缺陷。
修正或替换对超标的零部件应予以替换，对需修正的零部件，修正后应符合标准。组装及调整齿轮端面与端盖，托架的轴向空隙，依托改动端盖，托架与泵体之间的密封垫片的厚度来调整;紧固端盖螺栓时，用力对称均匀，边紧边盘动转子，遇到转子转不动时，应松掉螺栓重紧;加填料或装油封时，紧压盖时仍需边紧边盘动转子。
不可紧得过死。试车水压试验为工作压力的1.5倍，坚持5min不漏，试车运转期间，无泄漏，运转声响正常，无反常振动，出口压力符合要求为合格。布赫BUCHER齿轮泵的维修办法：齿轮泵轴磨损后的修补齿轮泵中轴的磨损主要是因为轴两头与支撑滚针间的冲突磨损，使轴径变小。假如是细微磨损，可通过镀一层硬铬来加大此部位轴的直径尺度。
使轴得到修正。假如轴磨损严峻，则应45钢或40cr钢从头制作，轴毛坯经粗、精车后，轴承部位要热处理，硬度为hrc60-65，然后再经磨削，使轴承合作部位外表粗糙度ra不大于0.32μm;轴的圆度和圆柱度允差为0.005mm;与齿轮合作部位按h7/h外表粗糙度ra应不大于0.63μm。
