拖拉机的细长轴类零件包括凸轮轴、变速箱传动轴等。这类零件如存放不当,易产生变形,会影响发动机配气正时及传动轴齿轮的正常啮合,从而影响拖拉机正常工作。因此保管时,一般应将这类零件水平放置于平板上,或用细绳栓住轴的一端,沿轴线方向垂直悬挂于墙壁上。对于凸轮轴,平放时 Tractor slender shaft parts include camshafts, transmission shaft and so on. Such parts, such as improper storage, easy to produce deformation, will affect the engine timing and gear shaft gear meshing, thus affecting the normal operation of the tractor. Therefore, custody, the general should be placed horizontally on the flat parts of such parts, or with a thin string to bolt one end of the shaft, hanging in the axial direction perpendicular to the wall. For camshafts, lay flat
