齿轮式机油泵的磨损大多发生在机油泵主动轴与衬套,被动齿轮中心孔与销配合表面;泵壳内腔与齿轮;齿轮端面与泵盖等处。如果磨损后主要技术指标已经达不到要求,就应将油泵拆卸分解,检查磨损程度和各配合处的破坏情况,并采取相应的措施进行修复。 主动轴与衬套的修复 机油泵主动轴与衬套磨损后,配合间隙将增大,影响泵油量,可采用修轴颈或修衬套的方法来恢复其配合间隙。在轴颈轻微磨损的情况下,只需压出旧衬 Most wear gear oil pump occurs in the oil pump drive shaft and bushings, the center pin and pin gear with the mating surface; pump housing cavity and gear; gear end and pump cover and so on. If the main technical indicators after wear have failed to meet the requirements, they should disassemble the pump to check the degree of wear and tear with the destruction of the cooperation Department, and take appropriate measures to repair. Drive shaft and bushing repair Oil pump drive shaft and bushing wear, with the gap will increase, affecting the pump oil, you can use the method of repair journals or repair bushing to restore its cooperation with the gap. In the case of slight wear of the journal, simply press the old lining
