电动叉车驱动桥壳的修理方法!

来源:/ 日期:2021-03-12 发布人:hangong

驱动桥壳坚固的安装在叉车车架上。由于驱动桥和车架是刚性联接,在叉取货物或搬运、堆垛作业中,驱动桥将承担大部分重量,而且还有道路不平、叉架载荷不均等的情况,这样驱动桥将出现弯曲、断裂,半轴套管轴承孔磨损和半轴套管轴颈磨损等损伤,大家该如何维修这些问题呢?
The drive axle housing is firmly installed on the forklift frame. Due to the rigid connection between the drive axle and the frame, the drive axle will bear most of the weight in the forking or handling and stacking operations, and there are uneven roads and uneven load on the forks. In this way, the drive axle will be bent and broken, the bearing hole of the axle shaft sleeve will be worn, and the axle journal of the axle shaft sleeve will be worn. How can we repair these problems?
1、电动叉车驱动桥壳弯曲的修理
1. Repair of drive axle housing bending of electric forklift
驱动桥壳弯曲超限时应进行校正。校正时,校正变形量应不大于原有弯曲变形量,并将校正压力保持一段时间,使桥壳有一定的塑性变形。如果变形过大,弯曲变形大于2mm时,可预热后校正、但加热温度不允许超过700℃。铸制的桥壳好避免加热校正。
When the bending of the drive axle housing exceeds the limit, it should be corrected. During the correction, the correction deformation should not be greater than the original bending deformation, and the correction pressure should be maintained for a period of time, so that the axle housing has a certain plastic deformation. If the deformation is too large and the bending deformation is more than 2mm, it can be corrected after preheating, but the heating temperature is not allowed to exceed 700 ℃. The cast axle housing can avoid heating correction.
2、电动叉车驱动桥壳断裂的修理,驱动桥壳中部裂纹及突缘上裂纹,可用焊接法修复,其操作要点如下:
2. The cracks in the middle of the drive axle housing and the cracks on the flange can be repaired by welding
(1)电焊焊补裂纹,其焊层应高于基本金属,但不超过1mm。正面焊好后再在反面进行焊补,焊后应将焊缝修平。焊补在工作平面的,其平面度误差应不大于0.25mm。
(1) The welding layer should be higher than the base metal, but not more than 1 mm. After the front side is welded, the back side shall be repaired, and the weld shall be leveled after welding. If the welding repair is on the working plane, the flatness error shall not be greater than 0.25 mm.

(2)裂纹焊补后应在裂纹处焊接加强腹板,其厚度一般为4-6mm,加强腹板应与驱动桥壳中心对称。
(2) After repairing the crack, the reinforcing web should be welded at the crack, the thickness of which is generally 4-6 mm, and the reinforcing web should be symmetrical with the center of the drive axle housing.
(3)如裂纹穿透至驱动桥壳盖或主减速器突缘平面,则在焊补后应另焊加强腹环。电动叉车驱动桥壳盖平面的加强腹环可复接于外面,主减速器壳则视内部空间的许可,应复接于内面。焊接加强腹环时,应先用螺栓将加强腹环紧压于平面上,以免焊接时位置移动和挠曲。
(3) If the crack penetrates to the surface of the drive axle housing cover or the flange of the main reducer, the reinforcing web ring should be welded after welding. The reinforcing web ring of the drive axle housing cover plane of the electric forklift truck can be multiplexed on the outside, while the main reducer housing should be multiplexed on the inside according to the permission of the internal space. When welding the reinforcing web ring, the reinforcing web ring should be pressed on the plane with bolts to avoid position movement and deflection during welding.
(4)焊补加强后的电动叉车驱动桥壳,要重新进行检验其直线度误差、壳盖面和主减速器突缘平面的平面度误差、并校正、修磨到符合标准。
(4) The straightness error, the flatness error of the cover surface and the flange plane of the main reducer of the electric forklift drive axle housing after the welding reinforcement shall be inspected again, and the straightness error shall be corrected and polished to meet the standard.
以上就是简单先容的电动叉车驱动桥壳断裂、弯曲的维修方法,希翼这几个方法对大家会有用处,如果还有什么其他问题欢迎随时联系大家网站:济南二手叉车,大家将尽力为您解决!
