During the operation of the reducer, axial displacement sometimes occurs, which usually leads to a poor network of mechanical gears, which then leads to unilateral mesh division problems, which affect the normal operation of the reducer.So why does the reducer have axial displacement?On this issue, we made the following presentations:
The two end faces of the reduction gear should be perpendicular to the shaft, and the plane formed by the symmetrical center points of the left and right helical gears should also be perpendicular to the shaft.However, there will be errors in the actual handling and assembly of the gears.After assembling the herringbone gear on the shaft with errors, the closed loop formed by the center of symmetry of its left and right rotating gears is not a plane perpendicular to the shaft, but a curved surface, and the curved surface is the surface that rotates around the shaft. The track is Irregular wavy curves, two different gear rotation tracks are two different curves.During the operation of a pair of meshed gears, their centerlines of symmetry coincide, therefore, the centerlines of symmetry of the pair of herringbone gears will coincide and overlap during the meshing of the gears, and the result is inevitably peak valley superposition, and also That is, errors accumulate and this causes axial displacement of the gear shaft.
From the above it can be seen that the axial displacement of the reducer is caused by the superposition of the two end face axes.Reduction manufacturers should pay attention to this in the design and production process to ensure that the reducer can also be used for a long time.
