把磨损了的花键联接件改装为方轴方孔联接一台E512型联合收割机的液压泵花键轴磨损严重,影响了液压泵的供油。因液压泵花键轴和油泵体内的齿轮是一体的,如要更换花键轴则整个泵将报废,会增加机车作业成本。为了不使整个泵报废,可以把磨损了的花键轴上的花键磨掉,然后再磨成截面呈长方形的轴,截面长13mm、宽11mm;与此相匹配,把传动带带轮轮毂车削掉,制作一个外形尺寸相同但中心为与长方形轴相匹配的长方形孔的轮毂压入并焊合。经上述改装后即可装复使用。 (许前黎)
The wear of the spline coupling modified square shaft hole connection E512 type combine harvester hydraulic pump spline shaft wear and tear, affecting the hydraulic pump oil. Because the hydraulic pump spline shaft and gear pump body is one, such as to replace the spline shaft, the pump will be scrapped, will increase locomotive operating costs. In order not to discard the entire pump, the worn spline shaft can be spooled off, and then ground into a rectangular section of the shaft cross-section length 13mm, width 11mm; with this, the drive belt pulley hub turning Off, making a hub of the same overall dimensions but centered on a rectangular hole matching the rectangular shaft to press in and weld. After the above modification can be installed to use. (Xu before Li)
