The undercut of the gear is how to produce?
To avoid undercutting measures:1, make the cut gear tooth counts more than the minimum tooth does not undercut the number2, reduce tooth addendum coefficient ha* or increase the cutter angle3, deflection correction method
Have serious consequences: the undercut undercut gear, a weakened tooth bending strength; on the other hand will enable lower gear transmission of this degree is very unfavorable.
Is a professional term undercutting machinery, the involute gear transmission, gear meshing line of the gear top and the intersection of A over the limit of cut gear meshing point, by involute gear is cut off part of the phenomenon. Edit summary of involute gear transmission, gear meshing line of the gear top and the intersection of A over the limit of cut gear meshing point, by involute gear is cut part, this phenomenon is called undercut. The number of teeth undercut generally appear in relatively few cases, in order to prevent undercutting in processing gear involute gear root will cut out a round, or using gear.
