Reversible deformation correcting method for elliptical gear ring subjected to deformation after carburization
InactiveCN101838730AControl expansionLow costFurnace typesHeat treatment furnacesOil coolingMinor axis
The invention provides a reversible deformation correcting method for an elliptical gear ring subjected to deformation after carburization, which comprises the following steps of: measuring the addendum circle diameters of a gear ring which is subjected to ellipse deformation after carburization every 30 degrees, wherein the difference between the measured addendum circle diameters is the major axis and the minor axis of the gear ring which is subjected to ellipse deformation; binding a layer of heat insulation cotton at both sides of the inner end surface of the gear ring in the minor axis-distributed area with iron wires at a moderate tightening degree; and exposing other gear rings and external gear parts. In the quenching process, the elliptical gear ring is heated to 810 DEG C at a heating rate of 60 DEG C / h and is kept for 4 hours. Because the minor axis-distributed area is covered with the heat insulation cotton, the heating rate of the minor axis-distributed area covered with the heat insulation cotton is smaller than that of the major axis-distributed area uncovered with the heat insulation cotton, and the cooling speed of the minor axis-distributed area of the gear ring is smaller than that of the major axis-distributed area in the quenching oil cooling process, thereby correspondingly reducing the difference between the distributed areas with different addendum circle diameters of the gear ring and consequently realizing the reversible deformation correction of the elliptical gear ring.
