1、叉车齿轮:齿轮外圆磨损和胶合,使其径向间隙变大,轻者对使用没有明显影响;严重者应更该换齿轮保护叉车其他零件的安全。
1. Forklift gear: the outer circle of the gear is worn and glued, making its radial clearance larger. If it is light, it has no obvious impact on the use; In serious cases, the gear should be replaced to protect the safety of other parts of the forklift.
2、齿轮两侧端面的磨损,如果不严重它只会起线,可用研磨将毛刺痕迹研磨去;当磨损严重的时候,可以拿去磨床上磨平。但是只要一只齿轮端面磨损的同时另一只齿轮也需同时磨削,以保证两只齿轮的厚度差在0.005mm左右。磨削时还应注意端面与孔、端面与端面的精度要高。磨削后应用油石磨去锐边毛刺,但不宜倒角。
2. If the wear of the end faces on both sides of the gear is not serious, it will only start the line, and the burr trace can be removed by grinding; When the wear is serious, you can take it to the grinder and grind it flat. However, as long as the end face of one gear is worn, the other gear also needs to be ground at the same time to ensure that the thickness difference between the two gears is about 0.005mm. During grinding, attention should also be paid to the high accuracy of end face and hole, end face and end face. After grinding, the sharp edges and burrs shall be removed with an oilstone, but chamfering is not suitable.
3、油泵齿轮都是单方向工作,因而齿面都是单面磨损。可将齿面磨损的齿轮用油石去掉毛刺,调换齿轮啮合方位,可恢复油泵的工作性能。
3. Oil pump gears work in one direction, so the tooth surface is worn on one side. The gear with worn tooth surface can be deburred with oilstone, and the meshing orientation of the gear can be changed to restore the working performance of the oil pump.
4、叉车齿轮轴承架:端面磨损或起线拉毛时,可将四只轴承架在平面磨床上,以非齿轮接触面为基准,一次将端面磨出。
4. Forklift gear bearing frame: when the end face is worn or the starting line is roughened, four bearing frames can be put on the surface grinder and the end face can be ground out at one time based on the non gear contact surface.
5、内孔一般磨损较小,若磨损严重时,可用研磨或将孔径磨大至修理尺寸、选配滚针。
5. Generally, the wear of the inner hole is small. If the wear is serious, grind the hole diameter to the repair size or select the needle roller.
6、装有侧板或轴向浮动的轴套磨损、划伤和沟痕时,可将损伤的表面进行抛光。方法是在平滑表面上放上no400-600的研磨膏,加上洗油或蜡在侧板表面上轻轻转动,进行抛光。
6. When the shaft sleeve with side plate or axial floating is worn, scratched and grooved, the damaged surface can be polished. The method is to put no400-600 grinding paste on the smooth surface, add washing oil or wax, and gently rotate on the side plate surface for polishing.
7、叉车齿轮泵体:泵体磨损一般发生在吸油腔,某些油泵从构造上可用换位法进行修理,即将泵体绕本身轴线180°,使吸油腔变成压油腔以恢复其工作能力。
7. Forklift gear pump body: the wear of the pump body generally occurs in the oil suction chamber. Some oil pumps can be repaired by transposition method in structure, that is, the pump body rotates 180 ° around its own axis to turn the oil suction chamber into an oil pressure chamber to restore its working capacity.
8、不能用换位法修理的油泵体,可用镶铜套法修复。
8. The oil pump body that cannot be repaired by transposition method can be repaired by inlaying copper sleeve method.
9、当齿轮因端面磨损而进行磨削后,为保持轴向间隙,需将泵体后端面磨至适当厚度。
9. When the gear is ground due to end face wear, in order to maintain axial clearance, the rear end face of the pump body needs to be ground to an appropriate thickness.
