Mesh is 1.The number of flank of tooth spray port is 2.Tooth root spray port is located between two flank of tooth spray ports.Dotted line represents injection in figure
Range.
Specifically, outer spray colunm 51 is arranged along each tooth socket in teeth portion, outer spray colunm 51 agrees with tooth socket, each outer spray
Leaching column 51 is distributed several outer spray ports on same tooth form normal section.It is larger to be located in the middle outer spray port size, sprays
Direction is root position, be located at the symmetrical office of left and right sides spray port, spray position be pitch circle nearby flank of tooth position, tooth top and
Peak Angle Position does not spray;On the axial direction of outer spray colunm 51, outer spray port arrangement is still intermediate intensive, upper and lower side
It is sparse at face.The distance of outer spray colunm 51 to part 200 is determined according to outer spray port angle and injection flow, pressure etc..As
A kind of specific embodiment, each outer spray colunm 51 3 outer spray ports of branch on same tooth form normal section.As optional
Embodiment, outer spray colunm is distributed 4 or 5 outer spray ports on same tooth form normal section.
After the completion of 200 Quench heating of part, part 200 is placed on hoistable platform 20, and by interior 40 He of spray equipment
Outer spray equipment 50 agrees with part 200, then enters in quenching liquid with part, is completely submerged in part 200
Quench liquid and it is steady after, start the first variable-frequency motor and the second variable-frequency motor install preset technique and carries out quenching cooling.
Ring gear is a kind of common driving member, is again provided with inner hole, and groundwork position is inner ring.Interior spray dress
Set that inside and outside contour in gear ring can be set with outer spray equipment is similar.The axis of spray angles and ring gear is in 7 ° of -45 ° of folders
Angle, interior spray apertures and outer spray apertures can be distributed using single row or multiple rows.The diameter of interior spray apertures and outer spray apertures be 1mm extremely
6mm.The flow velocity of inner ring and outer ring can be adjusted and can be realized cold by the first variable-frequency motor and the second variable-frequency motor
But the spray flow (or pressure) of the adjusting of speed, inner ring is greater than outer ring, so that the cooling rate of inner ring is greater than the cooling rate of outer ring, realizes cold
But initial stage cooling rate is fast, cooling later period cooling slow purpose.
