As described in Maruzen Co., Ltd., 4th edition, p. 1246), it is ``a device in which heating and cooling are sequentially performed from one end at a constant speed by a feeding device, and then the heating and cooling are carried out to the other end.'' Specifically, for example, after placing the outer ring 1 with its opening f'' side facing downward and inserting the high frequency heating coil from the lower part of the opening,
There is a moving quenching method in which the high-frequency heating coil is moved upwards or the outer ring is moved downwards to heat it sequentially, and then cooling water is jetted to the heated area to cool it sequentially. A one-shot quenching method, in which a high-frequency heating coil is placed inside the outer ring 1 with the outer ring 1 facing upward or downward, and then electricity is applied to heat the entire inner surface of the outer ring 1 at once, and then cooling water is jetted out for quenching. was there.

It passes between the inner periphery and the high-frequency heating coil core 17 from the bottom surface of the outer ring 11 and is ejected upward, so that the inner periphery of the outer ring 11 can be cooled during this time. At the same time, cooling water is jetted out from the nozzle 23a of the outer circumferential cooling liquid jacket 23 to cool the outer circumferential side of the outer ring 11.

れる。Next, after a time t1 shown in FIG. 4 has elapsed, the high-frequency heating coil 13 is energized, and the lower end of the inner peripheral surface of the outer ring 11 is heated by the high-frequency heating coil core 17. After heating is stopped for a time t2 shown in FIG. 4, the high-frequency heating coil 13
．． Coolant supply pipe 15, high frequency heating coil core 17. The outer circumferential coolant jacket 23 and the like are slowly moved upward together (or the support base 12 is moved downward together with the outer ring 11) to the position of point B shown in FIG. During this time,
The inner circumferential surface of the outer ring 11 is heated to a predetermined hardening temperature by high-frequency heating and then immediately cooled to undergo high-frequency hardening.

When the outer ring 11 reaches a point C' which is the upper end position of the outer ring 11, the outer ring 11 whose inner peripheral surface has been completely hardened is taken out.

０．０９ｍｍの非常に小さい焼入歪しか発生しなかった
。In this way, the inner circumferential surface of the outer ring 11 is heated and hardened at the same time, and according to an example of implementation, in induction hardening of the outer ring 11 with an inner diameter of 33.34 mm, in the conventional case, the inner diameter after quenching is In contrast, in the case of the present invention, the inner diameter after quenching was about 33.25 to 33.30 mm, which was about 0.04 to 33.30 mm.
Only a very small quenching strain of 0.09 mm occurred.

できるという特長を有している。In addition, in the case of underwater quenching, the cooling water stagnates, steam formation occurs, resulting in uneven quenching, and a considerable amount of electrical input is required. In the quenching method, a minimum amount of coolant is flowed to create a thin layer of water between the high-frequency heating means and the inner surface of the outer ring 11.
During the heating of the outer ring 11, this water film is continuously formed by a new coolant flow whose water temperature is controlled, so there is no uneven heating, and the water film is formed sequentially after the conventional heating. It has the advantage that it can be heated with approximately the same electric capacity as the electric capacity used during cooling moving quenching, and it can also save energy.

減をはかることができるという利点を有する。In the case of the embodiment shown in the figure, since the outer ring 11 is installed with its opening facing upward, the quenching range can be reduced to the bottom in 1 minute, and therefore the bottom can be quenched more easily than in the conventional case. Since the heat treatment effect is large, there is no need to increase the thickness of the bottom part, which has the advantage that the weight and amount of materials used can be reduced.

効果を有している。(Effects of the Invention) As described above, according to the present invention, when induction hardening a member having an appropriate wall thickness, the high frequency heating means is disposed on the hardened surface side of the member, and the Induction hardening is performed by supplying an appropriate amount of cooling liquid, for example, the minimum necessary amount, to the hardened surface side of the member and the opposite side thereof, and moving the high-frequency heating means appropriately while energizing the cooling liquid in the cooling liquid. Because of this, it is possible to significantly reduce the occurrence of quenching distortion during induction hardening of a member with an appropriate wall thickness, and it is possible to significantly improve the dimensional accuracy of the member after induction hardening. It is possible to uniformly harden the surface of the component without causing uneven heating.
In addition, since the high-frequency heating means is heated by electricity in the coolant, the high-frequency heating means is less deformed and has a longer life.Compared to the conventional transfer hardening method, the simultaneous hardening method of the present invention reduces the amount of heat in the coolant. It has very good effects such as easy management.
