分を研磨仕上げする工程により製作されている。[0004] The noise and vibration of the reduction gear unit 10 of the geared motor are caused by the high-speed rotating part, and the tooth profile of the high-speed rotating part needs to be finished with high precision. The motor shaft 2 bends in the heat treatment step of increasing the surface hardness of the first gear 2a of the reduction gear section, causing distortion of the diameter and the like. Each of the first gears 2a formed by hobbing is pre-processed leaving a finishing allowance, and heat-treated to form a hardened layer on the tooth profile surface as shown in FIG. It is manufactured by a process of polishing and finishing a portion where the bearing 4 and the like are mounted.

Therefore, a step of polishing and finishing after the heat treatment is required. Alternatively, any of high-frequency heat treatment may be performed, and heat treatment is performed so that the depth of the hardened layer is about 1 mm from the surface.

る。In some cases, the motor shaft 2 is formed with the first gear 2a by hobbing, subjected to high-frequency heat treatment, and finished by hobbing instead of polishing by a grindstone. In this case, the motor shaft 2 is already formed. Hobbing is performed to the extent that the first gear 2a is exposed, with a surface hardness of about HRC40 and a finishing allowance of about 0.1 to 0.2 mm.

点があった。As described above, in the conventional geared motor shown in FIG. 4, the first gear 2a of the motor shaft 2 is processed by leaving a finishing allowance from the material in order to reduce noise and vibration. High accuracy is ensured by two processes of pre-gearing and finishing by hobbing after heat treatment. However, the number of processing steps increases the manufacturing time and costs.

騒音、振動を低く抑えることができるものである。The magnitude of the vibration and noise of the geared motor is determined by the meshing state of the gears of the speed reducer 30, and generally, a helical gear is used so that the tooth profile becomes large and the meshing ratio becomes large. . Assuming that the torsion angle of the helical gear is β, the meshing ratio of the helical gear is proportional to tan β, and the larger the meshing ratio β, the more noise and vibration can be suppressed.

For example, in the case of the module 1.25, the required quenching depth is 3.3 mm from the finished gear outer diameter.

3 As shown in “High-efficiency machining of small-module high-hardness gears using a coated carbide hob”, a material SCM4 having a hardness of about 54 HRC can be obtained by using a carbide hob.
Forty gear cutting operations are possible. It has been shown that this method enables the gear cutting of the heat-treated material. However, in this method, the torsion angle is relatively small at 15 °, and the effect of reducing noise and vibration of the geared motor is small. In the case of the material SCM415 of HRC60 shown in the above document,
Hobbed before heat treatment. Further, the material SCM440 of the HRC 54 described in this document is described as induction hardening. However, in general induction hardening, the depth of the hardened layer is 0.5 to less than the surface (surface such as a tooth tip or a tooth surface). 1mm
And therefore it is not explicitly shown whether the document is a material that has been hardened to the root of the tooth.

できる。When the gear 22a formed on the motor shaft 22 is machined by a hobbing machine, the motor shaft 22 is cut by a cutting resistance.
Desired processing accuracy cannot be obtained. The amount of deflection of the shaft during hobbing is proportional to (1 / cos β) 3 , and the relationship between the module and the cutting resistance is as shown in FIG. 3. It is shown as. As the torsion angle β increases, the amount of deflection due to cutting resistance decreases. By increasing the torsion angle β to some extent, high-precision hobbing can be performed with a hobbing machine.

By quenching to about RC60 and performing a heat treatment so that the quenching hardness of the hardened layer becomes HRC50 to 58 by tempering, it is possible to perform processing by a super hard hob.

るのが適当である。Since the ratio of the meshing ratio of the helical gear with the helix angle β is proportional to tan β, the ratio of the ratio of the meshing ratio with the helix angle of 20 ° to the case of the helix angle of 15 ° is 1.36 times, and The torsion angle β of the gear is 20
It is well-known that noise and vibration are significantly reduced by setting the angle to not less than °. In addition, the amount of deflection at the time of gear cutting is reduced to 0.92 times in proportion to (1 / cos β) 3 , and from this point, it is better that the twist angle β is large. on the other hand,
When the torsion angle β increases, the axial load generated in the axial direction increases, and the axial load on the bearing increases. Therefore, the torsion angle β is limited to 30 °. For this reason, it is appropriate to select the twist angle β in the range of 20 ° to 30 °.

The motor shaft 22 has a quenching depth of about 4 mm from the finished gear outer diameter by high frequency heating, a hardness after quenching of HRC 50 to 58, a hardened layer depth of at least the tooth height, and a first gear 22a.
