低成本、率、以工作质量保证产品质量

驱动桥壳牢固地安装在叉车框架上。由于驱动桥与车架刚性连接，在拨叉、搬运和堆垛作业中，驱动桥将承受大部分重量，叉架上也存在路面不平和载荷不均匀的情况，导致驱动桥弯曲断裂，半轴套管的轴承孔和半轴套管的轴颈磨损。如何才能修复这些问题？

The drive axle housing is firmly mounted 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 during fork shifting, handling and stacking operations. Uneven road surface and uneven load also exist on the fork frame, resulting in the bending and fracture of the drive axle and the wear of the bearing hole of the half axle sleeve and the Journal of the half axle sleeve. How can these problems be fixed?

1、电动叉车驱动桥壳弯曲修复

1. Repair of drive axle housing bending of electric forklift

当驱动桥壳弯曲超过限度时，应进行校正。校正时，校正变形应不大于原弯曲变形，校正压力应保持一段时间，使桥壳有一定的塑性变形。如果变形过大，弯曲变形大于2mm，预热后可以校正，但加热温度不允许超过700。铸造桥壳可以避免加热校正。

When the bending of the drive axle housing exceeds the limit, it should be corrected. When correcting the plastic deformation of the axle housing, it should be kept within a certain period of time. 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. Cast axle housing can avoid heating correction.

2.修理电动叉车驱动桥壳断裂。驱动桥壳中部的裂纹和法兰上的裂纹可以通过焊接修复。操作要点如下：

2. Repair the broken drive axle housing of electric forklift. Cracks in the middle of the drive axle housing and on the flange can be repaired by welding. The operation points are as follows:
               

(1)焊接裂纹时，焊接层应高于基本金属，但不超过1毫米。正面焊接后，背面应进行补焊，焊接后焊缝应平整。在工作平面上进行焊接修复时，平面度误差不得大于0.25毫米.

(1) When welding cracks, the welding layer shall be higher than the base metal, but not more than 1 mm. After the front welding, the back should be repaired, and the weld should be flat after welding. The flatness error should not be more than 0.25 mm when welding on the working plane

(2)裂纹修复后，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 the crack is repaired, 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)如果裂纹穿透驱动桥壳盖或主减速器法兰平面，应在焊补后单独焊接加强腹环。电动叉车驱动桥盖平面上的加强腹环可以连接到外部，而主减速器壳应根据内部空间的允许连接到内部。焊接加强腹板环时，应使用螺栓将加强腹板环紧紧地压在平面上，以避免焊接时位置偏移和偏斜。

(3) If the crack penetrates the plane of the drive axle housing cover or the flange of the main reducer, the reinforcing web ring shall be welded separately after the repair welding. The stiffening Web Ring on the flat surface of the drive axle cover of the electric forklift truck can be connected to the outside, while the main reducer housing shall be connected to the inside according to the permission of the internal space. When welding the stiffening web ring, bolts should be used to press the stiffening web ring tightly on the plane to avoid position deviation and deflection during welding.

(4)电动叉车驱动桥壳主减速器盖面和法兰平面在焊接钢筋后的直线度误差、平面度误差应重新检查、校正和打磨，以符合标准。

(4) Straightness error and flatness error of main reducer cover and flange plane of drive axle housing of electric forklift after welding reinforcement shall be checked, corrected and polished again to meet the standard.
