Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Example 1
As shown in fig. 1-3, a heating tool for a tapered roller bearing retainer comprises an annular top plate 1 and an annular bottom plate 2 which are arranged in parallel up and down, wherein a plurality of supporting blocks 3 are arranged between the annular top plate 1 and the annular bottom plate 2, resistance wires 4 are arranged on the inner side wall of each supporting block 3 in a penetrating manner, and a containing cavity for containing the tapered roller bearing retainer 5 is formed by the annular bottom plate 2, the annular top plate 1 and the plurality of supporting blocks 3 in a surrounding manner. Preferably, the plurality of support blocks 3 are uniformly distributed between the annular bottom plate 2 and the annular top plate 1.
When the alternating magnetic field heating tool is used, the retainer 5 is arranged in the containing cavity of the heating tool through the gap of the base plate, and after the resistance wire 4 is electrified, the metal retainer 5 generates eddy current in the alternating magnetic field to heat the metal retainer.
In order to improve the heating efficiency, the resistance wire 4 of the present embodiment is spirally disposed on the support block 3. When in use, current is generated by electromagnetic induction, the current forms a spiral action route in the metal retainer 5, and heat generated by the current flow is absorbed by the retainer 5, so that the retainer 5 is heated up rapidly. The size of the retainer 5 is increased after the temperature is raised so as to ensure that the retainer 5 and the rolling bodies are smoothly sleeved with the inner ring.
Specifically, the inner diameter of the annular bottom plate 2 is matched with the minimum outer diameter of the retainer 5, the inner diameter of the annular top plate 1 is matched with the maximum outer diameter of the retainer 5, and the inner side surface of each supporting block 3 is provided with an inclined surface 3.1 matched with the tapered roller bearing retainer 5. The side wall of each supporting block 3, which is close to the inclined surface 3.1, is provided with a mounting hole 3.2 which is matched with the resistance wire 4.
Each support block 3 of the present embodiment is fastened between the annular bottom plate 2 and the annular top plate 1 by bolts 6 and nuts 7. During installation, the upper ends of the bolts 6 sequentially penetrate through the annular bottom plate 2, the supporting blocks 3 and the annular top plate 1 and then are screwed and fixed with the nuts 7. The structure is simple, and the installation is convenient.
The annular bottom plate 2, the annular top plate 1 and the supporting block 3 are all made of insulating materials. Preferably a bakelite plate.
In order to control the heating time and the heating temperature conveniently, the embodiment also comprises an electric box controller, and the resistance wire 4 is electrically connected with the electric box controller.
Compared with the prior art, the embodiment has the beneficial effects that:
in the heating tool for the tapered roller bearing retainer of the present embodiment, the metal retainer 5 generates eddy currents in an alternating magnetic field to generate heat itself. When the retainer 5 is placed in the alternating magnetic field after being placed in the heating tool, current is generated by electromagnetic induction, a spiral action route is formed in the metal retainer 5 by the current, and heat generated by the current flow is absorbed by the retainer 5, so that the retainer 5 is heated up rapidly. The size of the retainer 5 is increased after the temperature is raised so as to ensure that the retainer 5 and the rolling bodies are smoothly sleeved with the inner ring.
