As shown in FIGS. 1 and 2, the tooth portion 2 was constructed by continuously changing the module from the inner end 1a to the outer end 1b of the gear body 1, so this manufacturing method was For machining, a special and complicated cutting device must be used, resulting in a problem of high manufacturing costs. Further, for the same reason, the meshing partner is limited to bevel gears, so there is a problem that the scope of application is narrow. Note that 3 is the meshing pitch circle.

テーノξ−付き歯車は、ホブカッターによる切削加工が
可能であるので、製作コストが安くなる。In view of the above-mentioned problems, the present invention has a tooth portion configured by continuously changing the amount of dislocation from the inner end to the outer end of the gear body, thereby making it easier to manufacture a hob cutter isometric gear. The purpose of the present invention is to provide a gear with chi and g gears that can be manufactured using a simple cutting device to reduce manufacturing costs, and that can also be meshed with spur gears to widen the scope of application. Figures 3 to 6
To explain this based on one embodiment shown in the figure, 11 is a gear body, 12 is an inner end 11a to an outer end 1 of the gear body 11.
11], the tooth portion 13 is a meshing pitch circle formed by continuously changing the amount of dislocation. Therefore, for example, if the shift coefficients near the inner end 11a, the middle part, and the outer end 1lb are set to 0, 0.5, and 1, respectively, the tooth profiles at these locations are as shown in FIG. 4 (al, (b), respectively.
) and (C). That is, it is considered that the present tapered gear is made up of countless shifted gears in which the amount of shift gradually increases in the axial direction. As shown in Fig. 5, the surface machining of a non-tapered gear is performed by rotating the gear body 11 while holding it vertically at a constant speed, and moving the hob cutter 14 entirely diagonally downward, that is, displacing it downward. This is done by moving. Therefore, the present gear with ξ can be cut with a hob cutter, so the manufacturing cost is reduced.
又、不テーパー付き歯車は、上記構造から明らかなよう
に、第6図に示した如く平歯車15との噛み合いが可能
であるため適用範囲が極めて広い。Furthermore, as is clear from the above structure, the non-tapered gear can be meshed with the spur gear 15 as shown in FIG. 6, and therefore has an extremely wide range of applications.
上述の如く、不発明によるテーパー付き歯車は製作コス
トが安く且つ適用範囲が広いという実用上極めて重要な
利点を有している。As mentioned above, the uninvented tapered gear has the advantages of low manufacturing cost and wide range of application, which are very important practical advantages.
