Description
【考案の詳細な説明】 本考案はフェイスギヤ系の改良に関する。[Detailed explanation of the idea] The present invention relates to improvements in face gear systems.

いては噛合する両歯車の歯先円と歯元円との間には頂隙
が設けられている。A face gear system is one in which a small gear formed as a spur gear or a helical gear is meshed with a face gear created with a flat plane as a pitch plane.In the conventional face gear system, the tooth tip circles of both gears mesh. An apex gap is provided between and the dentinal circle.
ところが、このようなフェイスギヤ系においては、小歯

と正規の噛合位置が維持できなくなったり、また組付け
の際にフェイスギヤのピッチ面と小歯車の軸心との正規
の相対位置の設定が難しいという不都合があった。However, in such a face gear system, if the shaft of the pinion deviates perpendicularly to the shaft for some reason, the normal meshing position cannot be maintained, or the pitch surface of the face gear and There was a problem in that it was difficult to set the correct relative position to the axis of the pinion.

易で、しかも歯丈方向のがたをなくし転がりがスムース
なフェイスギヤを提供することを目的とする。In view of these points, the present invention provides a face gear that makes it easy to maintain the regular meshing position between the face gear and small gear of the face gear system, and that also eliminates play in the tooth length direction and rolls smoothly. The purpose is to
以下図面を参照して本考案の実施例について説明する。Embodiments of the present invention will be described below with reference to the drawings.

２はそれぞれ軸１ａおよび軸２ａを有している。In FIG. 1, a pinion 1 having a spur gear formed thereon is meshed with a face gear 2 similar to a crown gear, which has a generating gear cut with a plane as a pitch plane, and the pinion 1 and the face gear 2 each have a shaft 1a. and a shaft 2a.

A predetermined backlash of 1° is provided between and the tooth surface S6 of the tooth 2b of the face gear.
なお、第１図においては、小歯車１の歯形は平歯車であ

。In FIG. 1, the tooth profile of the pinion 1 is a spur gear, and although the axis of the pinion 1 and the axis of the face gear 2 do not intersect (off-center), the tooth profile of the pinion 1 is a spur gear. may be a helical gear, or the axis of the small gear 1 and the axis of the face gear 2 may be orthogonal (off-center).
以上説明したように、本考案はフェイスギヤの歯先と小
歯車の歯底とを接触させるようにして両歯車を噛合させ
たので、両歯車の歯の歯丈方向の噛合いずれがなくなり
、常に正規の噛合位置が保持される。As explained above, the present invention meshes both gears by bringing the top of the face gear into contact with the bottom of the small gear, so there is no misalignment in the tooth length direction of the teeth of both gears, and the gears are always in contact with each other. The normal meshing position is maintained.
また、両歯車の軸心に荷重が加わった場合にも小歯車の

、−ズとなるという効果を奏する。In addition, even when a load is applied to the axes of both gears, the contact between the bottom of the small gear and the tip of the face gear allows the proper meshing position to be maintained. By simply pressing both gears with a spring or the like and meshing both tooth surfaces, the relative positions of the shaft centers of both regular gears can be determined, making it easy to fix the shaft centers. The rotation is smooth because it prevents deviation from the axis of the
