叉车在使用中,常常会出现液压泵齿轮箱传动轴偏斜的情况。其危害是,噪声增大,加速了传动轴和两端轴套的早期磨损,影响齿轮及液压泵的寿命,增加维修难度。通过检测、分析知,主要原因是:叉车在出厂前的装配过程中,发动机动力输出轴至传动轴再至齿轮箱的输入轴的同轴度未达到要求,使之在使用中传动轴的偏斜越来越严重;由于操作不当或其他原因,使叉车和其他车辆或物体相撞,致使 In the use of forklifts, hydraulic pump gearbox shaft often appear skew situation. The harm is that noise increases, accelerating the drive shaft and both ends of the sleeve early wear and tear, affecting the life of gears and hydraulic pumps, increasing the difficulty of maintenance. Through testing, analysis, the main reason is: the forklift in the factory assembly process, the engine power output shaft to the gear shaft and then to the input shaft of the gear box does not meet the requirements of the coaxial, so that the use of the transmission shaft deviation Oblique more and more serious; due to improper operation or other reasons, the forklift and other vehicles or objects collide, resulting in
