1.磨损原因 135柴油机B型喷油泵往柴油机上安装形式为搭子式,以喷油泵壳体下弧面定位。长期使用后,尤其是在搭子螺栓松动的情况下,弧面与喷油泵安装托架结合处常磨损出环状带,严重时环状带磨损量常达0.3～1.5毫米。喷油泵位置下降,驱动喷油泵的被动接盘或提前器中心轴线下移,导致与主动接盘中心轴线的同轴度超差。主动接盘除了给被动接盘一个旋转力矩外,还要给凸轮轴前轴一个向上托起的径向力,
1. Wear reasons 135 Diesel B-type injection pump installed on the diesel engine to take the form of sub-type to the injection pump housing under the arc positioning. Long-term use, especially in the sub-bolts loosening case, the arc and fuel injection pump mounting bracket often wear out the annular zone, severe annular zone wear often up to 0.3 to 1.5 mm. The position of the fuel pump is lowered, the passive disk driving the fuel pump or the center axis of the advancer is moved downward, resulting in that the coaxiality with the center axis of the active disk is out of tolerance. In addition to take the initiative to take the passive disk access to a rotating torque, but also to the camshaft front axle up a radial force,
