But this approach also has the following problems:
the existence of the arc channels and the existence of the shaft shoulders lead the workpiece to be heated unevenly, the temperature of the edge of the shaft shoulders of the protrusions of the workpiece and the transition positions of the two channels is higher, the temperature of the root parts of the channels is lower, in order to quench the root parts of the channels, the heating time is prolonged, or the power of an inductor is increased, but the heating time is prolonged, and the production efficiency is reduced; increasing the power can increase the temperature of the shoulder edge and the transition position of the two channels, so that quenching cracks appear at the two positions.
Because the upper channel and the lower channel are in arc transition, the problem that the workpiece channel is heated unevenly and the heat shape is poor exists in the upper channel and the lower channel which are heated simultaneously by one turn of the induction coil, meanwhile, the depth of a heating layer is too deep at the edge of a shaft shoulder or the corner position of the adjacent channel easily, on one hand, the structure is thicker after quenching, and on the other hand, quenching cracks can occur when the temperature is too high.

In addition, in prior art, if adopt single circle induction coil to heat the upper and lower channel simultaneously, can have to lengthen the time of heating or increase the power of inductor because of the quenching condition that needs to take into account the channel root, but this scheme is because the inductor is single circle and is located not co-altitude, so the projection of three-layer induction section on the bearing terminal surface staggers the setting, so can set up the induction section that corresponds upper channel or lower channel and be close to the channel root more, improves heating efficiency and heating homogeneity, and then improves production efficiency. Meanwhile, after the induction sections of the middle layer and the induction sections of the lower layer are staggered, the heating heat of the transition positions of the upper channel and the lower channel is reduced, so that the quenching temperature is more uniform, the depth of a hardening layer is more uniform, and the probability of quenching cracks at the transition positions of the two channels due to the fact that the heating time is prolonged is reduced.
Besides, the adjacent induction sections on the circumferential projection are connected through the longitudinal connecting sections, longitudinal current exists on the longitudinal connecting sections when the bearing is used, and corresponding longitudinal current exists on the surface of the workpiece due to the longitudinal current, so that longitudinal heating is formed on the workpiece, and along with continuous rotation of the workpiece in the quenching process, the workpiece is heated from the shaft shoulder to the lower channel in the longitudinal direction, so that the continuity of the quenching layer in the axial direction of the bearing is ensured, and the quality of the bearing after quenching is further improved.
