本発明は一体成形歯車に係り、さらに詳しくばかさ歯車
および他の少フぐとも１つの歯車とのプラスチック成形
や金属の鋳型成形による一体成形歯車に関するものであ
る。[Detailed Description of the Invention] [Technical Field] The present invention relates to an integrally formed gear, and more particularly to an integrally formed gear formed by plastic molding or metal molding with a bevel gear and at least one other gear. It is.
従来より、かさ歯車と他の少なくとも１つの歯車とを一
体成形したプラスチックなどから成る歯車が知られてい
る。2. Description of the Related Art Conventionally, gears made of plastic or the like are known in which a bevel gear and at least one other gear are integrally molded.
第１図にその一例を示す。An example is shown in FIG.
すなわちかさ歯車部１および平歯車部３は連結部２を介
して一体化されている。That is, the bevel gear part 1 and the spur gear part 3 are integrated via the connecting part 2.
これをプラスチックによシ成形する場合には、４個のブ
ロックから成る型を用いていた。When molding this from plastic, a mold consisting of four blocks was used.
すなわち、゛かさ歯車部１および平歯車部３を成形する
２個１組のブロックと、連結部２を成形する２個１組の
スライド用ブロック、の計４個である。That is, there are a total of four blocks: a set of two blocks for forming the bevel gear portion 1 and the spur gear portion 3, and a set of two slide blocks for forming the connecting portion 2.
そしてこれらのブロックによって成形が成された後にお
いては、かさ歯車１成形用のブロックを矢印Ａ方向へ、
平歯車部３成形用のブロックを矢印Ｂ方向へ、連結部２
成形用のブロック２個は矢印ＣおよびＤ方向へ、それぞ
れ移動させて成形品を型から取り出す。After forming the blocks using these blocks, move the block for forming the bevel gear 1 in the direction of arrow A.
Move the block for forming the spur gear part 3 in the direction of arrow B, and move it to the connecting part 2.
The two molding blocks are moved in the directions of arrows C and D, respectively, and the molded product is taken out from the mold.
以上のように構成された一体成形歯車においては、１個
の製品につき４個のブロックから成る型が必要であり、
型構造が複雑で製造工数も多くなりコストが高くなって
しまうという欠点があった。In the integrally molded gear configured as described above, a mold consisting of four blocks is required for one product.
The disadvantage is that the mold structure is complex, the number of manufacturing steps is large, and the cost is high.
また、鋳型を用いた金属成形の場合にも同様の欠点が生
じていた。Similar drawbacks have also occurred in metal forming using molds.
本発明は以上のような従来の欠点を除去するために成さ
れたもので、成形用の型構造を簡略化しコストダウンを
実現できる一体成形歯車を提供することを目的としてい
る。The present invention was made in order to eliminate the above-mentioned conventional drawbacks, and an object of the present invention is to provide an integrally molded gear that can simplify the mold structure for molding and reduce costs.
以下、図面に示す実施例に基づいて本発明の詳細な説明
する。Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.
第２図は本発明の一実施例を説明するもので、同図から
明らかなように本発明においては、かさ歯車部１および
平歯車部３の連結部４はかさ歯車部１の最大径部の歯形
を軸方向に沿って延長した形状を採用している。FIG. 2 explains one embodiment of the present invention, and as is clear from the figure, in the present invention, the connecting portion 4 between the bevel gear portion 1 and the spur gear portion 3 is located at the largest diameter portion of the bevel gear portion 1. The tooth profile is extended along the axial direction.
すなわち、連結部４はかさ歯車部１の最大径部と同径で
、かつ連続した構造となっている。That is, the connecting portion 4 has the same diameter as the maximum diameter portion of the bevel gear portion 1 and has a continuous structure.
以上のような構造の歯車を一体成形する場合には、かさ
歯車部１および連結部４を成形するブロックと、平歯車
部３を成形するブロックのわずか２つのブロックから成
る型を用いれば良い。When integrally molding a gear having the above structure, it is sufficient to use a mold consisting of only two blocks: a block for molding the bevel gear part 1 and the connecting part 4, and a block for molding the spur gear part 3.
また、成形後において型を取り外す場合にも、かさ歯車
部１および連結部４成形用のブロックを矢印穴方向へ、
平歯車部３成形用のブロックを矢印Ｂ方向へそれぞれ移
動するだけで良い。Also, when removing the mold after molding, move the block for molding the bevel gear part 1 and the connecting part 4 in the direction of the arrow hole.
It is sufficient to simply move the blocks for forming the spur gear portion 3 in the direction of arrow B.
すなわち、簡単な型構造で、しかも少ない工数で一体成
形歯車を得ることができる。That is, an integrally molded gear can be obtained with a simple mold structure and with fewer man-hours.
なお、材質としてはプラスチック、金属のどちらの場合
にも本発明が適用され得ることはもちろんである。It goes without saying that the present invention can be applied to both plastic and metal materials.
また、本実施例にあってはかさ歯車と１個の平歯車とを
一体成形したものについて例示したが、かさ歯車と２個
以上の平歯車、あるいはかさ歯車と平歯車以外の歯車と
の一体成形歯車についても本発明は適用することができ
る。In addition, in this embodiment, a bevel gear and one spur gear are integrally molded, but a bevel gear and two or more spur gears, or a bevel gear and a gear other than a spur gear are integrally molded. The present invention can also be applied to molded gears.
以上の説明から明らかなように本発明によれば、かさ歯
車と他の歯車との連結部の形状として、かさ歯車の最大
径部の歯形を軸方向に沿って延長した形状を採用してい
るため、成形時に用いる型の構造を簡略化でき、製造工
数を減少させることができ、安価な一体成形歯車を得る
ことができる。As is clear from the above description, according to the present invention, the shape of the connecting portion between the bevel gear and another gear is such that the tooth profile of the maximum diameter portion of the bevel gear is extended along the axial direction. Therefore, the structure of the mold used during molding can be simplified, the number of manufacturing steps can be reduced, and an inexpensive integrally molded gear can be obtained.
