ない欠点があった。Conventional technology Conventionally, in order to improve the various performances of gears by ensuring the thickness of the resin coating film, finishing of the tooth surfaces of resin-coated gears after coating has been done using a cutter such as a hob or a gear shaver. The tooth profile has been modified,
A method of ensuring the precision of the coated tooth surface is to further perform finishing processing such as shaving processing as necessary. Figure 6 shows a conventional tooth surface finishing method, in which the blade surface (D) of a shaving cutter (N) fixed to the axis fB) is attached to the tooth surface (C) of a resin-coated gear to be machined (C). This indicates that the trout is processed in a normal meshing state by shaving processing, and even if it is processed to match the phase of the tooth profile (I) before being coated with resin by hobbing or gear shaver, it is actually It was a difficult task to precisely match the phase of the tooth profile (group) because of the difference in the thickness of the resin coat film (FL (G). Therefore, in the end, the result was that the tooth profile was machined after the resin coat tooth surface. The relationship between the film thickness (hl) of the advancing surface (F') in the advancing direction where the tooth surface is rotary cut and the film thickness (h2) of the retreating surface (G') on the opposite side is hl.
〉h2, the difference will be large), even if the above-mentioned hob or gear shaver processing is further performed using the shaving cutter shown in Fig. 6, the conventional method will not remove the resin. Machining follows the tooth surfaces with different coating thicknesses, and the advancing surface of the tooth profile (
The F′) side and the retreating surface (σ) side are machined to the same machining allowance, and the difference between the film thickness (h+) and film thickness (h2) is not resolved.
Although the precision of the tooth surface is improved by shaving, it is impossible to correct the thickness of the resin coating film on the tooth surface, and there is a drawback that variations in film thickness cannot be reduced.

することを目的としている。Purpose of the Invention In view of the drawbacks of the processing method using the conventional apparatus described above, the present invention provides a method to finish the tooth surface of a gear coated with a resin so that there is no difference in the thickness of the resin coating film when a shaving cutter or the like is engaged with the tooth surface. In other words, a phasing gear is combined with a shaving cutter to prevent the difference between the film thickness on the forward side being cut and the film thickness on the opposite side, the retreating side. The shaving cutter can be engaged with the predetermined tooth surface of the part that is not covered.By ensuring a uniform coating film thickness with no variation, the gear's wear resistance, rolling fatigue resistance, and working life are improved. 2. It is an object of the present invention to provide a method for processing a resin-coated gear that can improve the amount of elastic deformation and the noise prevention effect of the gear.

である。Effects of the Invention The present invention has the above-described configuration 1, and in finishing the tooth surface of a gear coated with a soft resin, the phasing gear of a shaving cutter and the unattached portion of the resin coated gear are treated. Because the resin-coated tooth surface is shaved for meshing with the tooth surface, it has the effect of ensuring an even film thickness without any variation in the resin-coat film thickness. Specifically, a thin, uniform coating film is effective for gear wear resistance and rolling fatigue life, and a thick, uniform coating film can be expected to have a large elastic deformation, which can be expected to have a noise prevention effect. It is effective because it allows the coating film thickness to be adjusted to these usage conditions without variation.
As mentioned above, this has the effect of improving the performance of the gear in many ways, such as the wear resistance of the gear and the prevention of noise.
