Description

この発明は、歯車の回転駆動を被駆動体に伝達する駆動伝達装置に関するものである。   The present invention relates to a drive transmission device that transmits a rotational drive of a gear to a driven body.

従来、歯車の回転伝達は、歯車列を用いて、双方の歯車の歯を噛み合わせて行われている。そして、歯車の歯の形状は、通常インボリュート形状であり、回転伝達時には、その歯面同士が接し、摩擦損失ができるだけ発生しないようになっている（例えば、下記の特許文献１参照）。   Conventionally, transmission of rotation of a gear is performed by meshing the teeth of both gears using a gear train. The tooth shape of the gear is usually an involute shape, and the tooth surfaces are in contact with each other at the time of rotation transmission so that friction loss does not occur as much as possible (see, for example, Patent Document 1 below).

特開平８−２３３０６２JP-A-8-233062

しかし、歯面同士が接して回転を伝達する際には、不可避的に滑り摩擦損失が発生している。   However, when the tooth surfaces are in contact with each other to transmit the rotation, sliding friction loss inevitably occurs.

この発明は上記に鑑み提案されたもので、歯車の回転伝達時の摩擦損失を極力小さくすることができる駆動伝達装置を提供することを目的とする。   The present invention has been proposed in view of the above, and an object of the present invention is to provide a drive transmission device capable of minimizing friction loss during transmission of rotation of a gear.

上記目的を達成するために、請求項１に記載の発明は、歯車の回転駆動を被駆動体に伝達する駆動伝達装置において、上記歯車と、上記歯車によって駆動される被駆動体と、を備え、上記被駆動体は、板状体と、上記板状体の面に等間隔に立設された、断面形状が円形である円形体と、を有し、上記歯車が回転駆動すると、歯車の各歯が、被駆動体の各円形体に順次当接して被駆動体を駆動させる、ことを特徴としている。   In order to achieve the above object, a first aspect of the present invention provides a drive transmission device for transmitting a rotational drive of a gear to a driven body, comprising the gear and a driven body driven by the gear. The driven body includes a plate-like body, and a circular body having a circular cross-sectional shape that is erected at equal intervals on the surface of the plate-like body, and when the gear is driven to rotate, Each tooth sequentially contacts each circular body of the driven body to drive the driven body.

また、請求項２に記載の発明は、上記の請求項１に記載の発明において、上記円形体は、円柱状または円筒状とするものである。   According to a second aspect of the present invention, in the first aspect of the present invention, the circular body has a columnar shape or a cylindrical shape.

請求項３に記載の発明は、上記の請求項１または２に記載の発明において、上記円形体は、ベアリングによって回転自在とするものである。   The invention described in claim 3 is the invention described in claim 1 or 2, wherein the circular body is rotatable by a bearing.

請求項４に記載の発明は、上記の請求項１から３の何れか１項に記載の発明において、上記歯車は平歯車とするものである。   The invention described in claim 4 is the invention described in any one of claims 1 to 3, wherein the gear is a spur gear.

請求項５に記載の発明は、上記の請求項１から４の何れか１項に記載の発明において、上記被駆動体の駆動は回転駆動とするものである。   The invention according to claim 5 is the invention according to any one of claims 1 to 4, wherein the driven body is driven to rotate.

請求項６に記載の発明は、上記の請求項１から４の何れか１項に記載の発明において、上記被駆動体の駆動は直進駆動とするものである。   According to a sixth aspect of the invention, in the invention according to any one of the first to fourth aspects of the invention, the driven body is driven linearly.

本発明の駆動伝達装置は、歯車が回転駆動すると、歯車の各歯が、被駆動体の各円形体に順次当接するようにしたので、歯車の歯面は、円形体の外周面に接しつつ、円形体に力を加え、被駆動体を駆動させる。すなわち、歯車の歯は、大きな曲率（半径ｒの逆数）を有する円形体の外周面に接することとなり、これにより歯と円形体との間の滑り摩擦は低減し、歯車の回転伝達時の摩擦損失を極力小さくすることができる。   In the drive transmission device according to the present invention, when the gear is driven to rotate, each tooth of the gear sequentially comes into contact with each circular body of the driven body, so that the tooth surface of the gear is in contact with the outer peripheral surface of the circular body. Then, a force is applied to the circular body to drive the driven body. That is, the teeth of the gear are in contact with the outer peripheral surface of the circular body having a large curvature (the reciprocal of the radius r), thereby reducing the sliding friction between the teeth and the circular body, and the friction during transmission of the rotation of the gear. Loss can be minimized.

また、この発明では、円形体をベアリングを介して回転自在となるようにしたので、歯と円形体との間の摩擦は転がり摩擦となってより一層低減し、歯車の回転伝達時の摩擦損失を大幅に小さくすることができる。   Further, in the present invention, since the circular body is made rotatable via the bearing, the friction between the teeth and the circular body is further reduced as rolling friction, and the friction loss during transmission of the rotation of the gear Can be significantly reduced.

以下にこの発明の実施の形態を図面に基づいて詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

図１はこの発明の駆動伝達装置を概略的に示す図、図２は図１のＩ−Ｉ線断面を示す図である。これらの図において、この発明の駆動伝達装置１は、歯車２の回転駆動を伝達する装置であり、歯車２と、この歯車２によって回転される回転体（被駆動体）３とを備えている。   FIG. 1 is a diagram schematically showing a drive transmission device according to the present invention, and FIG. 2 is a diagram showing a cross section taken along line II of FIG. In these drawings, a drive transmission device 1 of the present invention is a device for transmitting the rotational drive of a gear 2 and includes a gear 2 and a rotating body (driven body) 3 rotated by the gear 2. .

歯車２は、平歯車タイプのもので、中心の軸２０を中心に回転自在に設けられている。   The gear 2 is of a spur gear type and is provided so as to be rotatable around a central shaft 20.

回転体３は、中心の軸３０を中心に回転自在に設けられ、板状体３１と、板状体３１の面３１ａに垂設された複数の円形体４とを有している。この円形体４の各々は、円柱状または円筒状のものであり、板状体３１の面３１ａに円周状等間隔に設けられ、板状体３１の面３１ａと平行な面での断面形状が円形になっている。   The rotator 3 is provided so as to be rotatable about a central shaft 30, and includes a plate-like body 31 and a plurality of circular bodies 4 provided vertically on a surface 31 a of the plate-like body 31. Each of the circular bodies 4 has a columnar shape or a cylindrical shape, and is provided on the surface 31a of the plate-like body 31 at equal circumferential intervals, and a cross-sectional shape on a plane parallel to the surface 31a of the plate-like body 31. Is circular.

次に、円形体４の構成を図３、図４を用いて詳細に説明する。図３は図２の部分Ａを拡大した図で、円形体の構成図である。図４は円形体の取り付け手順を示す図である。図３、図４において、円形体４は、ベアリング部４１と、軸部４２と、円周部４３とから構成される。   Next, the configuration of the circular body 4 will be described in detail with reference to FIGS. FIG. 3 is an enlarged view of a portion A in FIG. 2, and is a configuration diagram of a circular body. FIG. 4 is a diagram showing a procedure for attaching a circular body. 3 and 4, the circular body 4 includes a bearing portion 41, a shaft portion 42, and a circumferential portion 43.

ベアリング部４１は、板状体３１に円周状等間隔に穿設された取り付け凹部３１１に嵌入して設けられている。   The bearing portion 41 is provided by being fitted into mounting recesses 311 formed in the plate-like body 31 at equal circumferential intervals.

軸部４２は、図４に示すように、上半部４２ａと基部４２ｂとからなり、上半部４２ａは、略柱状で基部４２ｂ側に向けて縮径し、基部４２ｂは円板状に形成されている。円周部４３は、略円筒状でその内周面は図中上方に向けて拡径している。   As shown in FIG. 4, the shaft portion 42 includes an upper half portion 42a and a base portion 42b. The upper half portion 42a has a substantially columnar shape and is reduced in diameter toward the base portion 42b, and the base portion 42b is formed in a disc shape. Has been. The circumferential portion 43 has a substantially cylindrical shape, and its inner circumferential surface has a diameter that increases upward in the drawing.

この円周部４３には、軸部４２が図中円周部４３の上方から挿入され、円周部４３の内部に軸部４２の上半部４２ａが嵌合され固定される。このとき、軸部４２の基部４２ｂは、円周部４３の下方に突き出した状態となり、この基部４２ｂは、板状体３１に固定されたベアリング部４１の内輪側に嵌入固定される。したがって、円形体４の円周部４３は、軸部４２と一体にベアリング部４１によって回転自在となる。   A shaft portion 42 is inserted into the circumferential portion 43 from above the circumferential portion 43 in the figure, and an upper half portion 42 a of the shaft portion 42 is fitted and fixed inside the circumferential portion 43. At this time, the base portion 42 b of the shaft portion 42 protrudes below the circumferential portion 43, and the base portion 42 b is fitted and fixed to the inner ring side of the bearing portion 41 fixed to the plate-like body 31. Accordingly, the circumferential portion 43 of the circular body 4 is rotatable by the bearing portion 41 integrally with the shaft portion 42.

歯車２の軸２０と、回転体３の軸３０とは平行に固定して設けられ（図２）、駆動伝達装置１は、歯車２の各歯２ａと回転体３の各円形体４とが噛み合うように構成される。そして、歯車２が回転駆動すると、歯車２の各歯２ａが、回転体３の各円形体４に順次当接して回転体３を回転させる。このとき、歯車２の各歯２ａの歯面は、円形体４の円周部４３の外周面に接しつつ、円形体４に力を加え、回転体３を回動する。したがって、歯２ａは、曲率（半径ｒの逆数）の大きな軸状の円形体４の外周面に接することとなり、双方間の摩擦は低減し、歯車２の回転伝達時の滑り摩擦損失を極力小さくすることができる。   The shaft 20 of the gear 2 and the shaft 30 of the rotating body 3 are fixed in parallel (FIG. 2), and the drive transmission device 1 includes the teeth 2a of the gear 2 and the circular bodies 4 of the rotating body 3. Configured to engage. When the gear 2 is driven to rotate, the teeth 2a of the gear 2 sequentially come into contact with the circular bodies 4 of the rotating body 3 to rotate the rotating body 3. At this time, the tooth surface of each tooth 2 a of the gear 2 is in contact with the outer peripheral surface of the circumferential portion 43 of the circular body 4 and applies force to the circular body 4 to rotate the rotating body 3. Therefore, the tooth 2a comes into contact with the outer peripheral surface of the shaft-like circular body 4 having a large curvature (the reciprocal of the radius r), the friction between both is reduced, and the sliding friction loss during the rotation transmission of the gear 2 is minimized. can do.

また、この発明の実施形態では、円形体４をベアリング部４１を介して回転自在となるようにしたので、歯２ａと円形体４との間の摩擦は転がり摩擦となってより一層低減し、歯車２の回転伝達時の摩擦損失をさらに大幅に小さくすることができる。   Further, in the embodiment of the present invention, since the circular body 4 is rotatable via the bearing portion 41, the friction between the teeth 2a and the circular body 4 becomes rolling friction and is further reduced. The friction loss at the time of rotation transmission of the gear 2 can be further greatly reduced.

次に、円形体４の各種変形例を図５、図６、図７を用いて説明する。   Next, various modifications of the circular body 4 will be described with reference to FIGS. 5, 6, and 7.

図５は第１の変形例を示し、ベアリング部の厚みをより増して円形体を構成した場合を示す図である。この第１の変形例における円形体４ｇは、図４のベアリング部４１に対し、ベアリング部４１ｇを図中上下２カ所とし、それに応じて軸部４２の基部４２ｂも厚み（高さ）を増し、これにより軸部４２を板状体３１にさらに深く組み込むことができ、円形体４ｇをより安定した構造とすることができる。   FIG. 5 is a diagram showing a case where a circular body is formed by increasing the thickness of the bearing portion, showing a first modification. The circular body 4g in the first modified example has two bearing portions 41g in the drawing in the upper and lower portions with respect to the bearing portion 41 in FIG. 4, and the base portion 42b of the shaft portion 42 also increases in thickness (height) accordingly. As a result, the shaft portion 42 can be incorporated deeper into the plate-like body 31, and the circular body 4g can have a more stable structure.

図６は第２の変形例を示し、ベアリング部を板状体の面から突出させた場合を示す図である。この第２の変形例における円形体４ｈは、先ず板状体３１の取り付け凹部３１１に、円筒状の枠体４５を嵌入し、次にその枠体４５の内周面に、軸部４２０の基部４２０ｂを嵌め込み、さらに軸部４２０の上半部４２０ａにベアリング部４１０を嵌入し固定することにより構成されている。この構成により、歯車２の各歯２ａは、ベアリング部４１０の外周面に直接接することになる。   FIG. 6 shows a second modification, and shows a case where the bearing portion is protruded from the surface of the plate-like body. In the circular body 4h in the second modified example, the cylindrical frame 45 is first fitted into the mounting recess 311 of the plate-like body 31, and then the base portion of the shaft 420 is placed on the inner peripheral surface of the frame 45. 420 b is fitted, and the bearing portion 410 is fitted and fixed to the upper half portion 420 a of the shaft portion 420. With this configuration, each tooth 2 a of the gear 2 is in direct contact with the outer peripheral surface of the bearing portion 410.

図７は第３の変形例を示す図である。この第３の変形例における円形体４ｉは、円筒状の円周部４３ｉを直接板状体３１の取り付け凹部３１１に嵌め込み固定したものであり、より簡単に円形体４ｉを構成することができる。   FIG. 7 is a diagram showing a third modification. The circular body 4i in the third modification is formed by fitting a cylindrical circumferential portion 43i directly into the mounting recess 311 of the plate-like body 31 and fixing the circular body 4i more easily.

図８は第４の変形例を示す図で、図８（ａ）はその構成を示す図、図８（ｂ）は組み付け手順を示す図である。この第４の変形例における円形体４ｊは、止着片４２１と円筒体（円周部）４３ｊとボルト４２５とから構成されている。止着片４２１は、円柱部４２３と、その円柱部４２３の上部で円盤状に拡径した頭部４２２とからなり、円柱部４２３には側方から取着穴４２４が設けられている。組み付ける手順は、先ず円筒体４３ｊを止着片４２１の円柱部４２３に挿入した状態で円柱部４２３を板状体３１の取り付け凹部３１１に挿入し、続いて板状体３１の側方に開設されたボルト係止用の穴３１２からボルト４２５を入れて、止着片４２１の取着穴４２４にそのボルト４２５を螺入する。このようにして、止着片４２１が板状体３１に固定され円形体４ｊが構成される。歯車２の各歯２ａは、円筒体４３ｊの外周面に接することになる。   8A and 8B are diagrams showing a fourth modification. FIG. 8A is a diagram showing the configuration, and FIG. 8B is a diagram showing an assembling procedure. The circular body 4j in the fourth modified example includes a fastening piece 421, a cylindrical body (circumferential portion) 43j, and a bolt 425. The fastening piece 421 includes a cylindrical portion 423 and a head portion 422 whose diameter is increased in a disc shape at the upper portion of the cylindrical portion 423, and the cylindrical portion 423 is provided with attachment holes 424 from the side. The assembly procedure is as follows. First, the cylindrical portion 423 is inserted into the mounting recess 311 of the plate-like body 31 in a state where the cylindrical body 43j is inserted into the cylindrical portion 423 of the fastening piece 421, and then opened to the side of the plate-like body 31. The bolt 425 is inserted from the bolt locking hole 312 and the bolt 425 is screwed into the attachment hole 424 of the fastening piece 421. In this way, the fastening piece 421 is fixed to the plate-like body 31 to form the circular body 4j. Each tooth 2a of the gear 2 is in contact with the outer peripheral surface of the cylindrical body 43j.

なお、円筒体４３ｊは、止着片４２１の頭部４２２と、板状体３１の上面との間に固定されていてもよいし、あるいは止着片４２１の円柱部４２３に遊嵌された状態で円筒体４３ｊを取り付け、円筒体４３ｊを止着片４２１に対して回転自在となるようにしてもよい。   The cylindrical body 43j may be fixed between the head 422 of the fastening piece 421 and the upper surface of the plate-like body 31, or may be loosely fitted to the columnar portion 423 of the fastening piece 421. The cylindrical body 43j may be attached so that the cylindrical body 43j is rotatable with respect to the fastening piece 421.

以上述べたように、この発明の駆動伝達装置１は、歯車２が回転駆動すると、歯車２の各歯２ａが、回転体３の各円形体４（４ｇ、４ｈ、４ｉ、４ｊ）に順次当接して回転体３を回転させる。このとき、歯車２の各歯２ａの歯面は、円形体４（４ｇ、４ｈ、４ｉ）の外周面に接しつつ、円形体４（４ｇ、４ｈ、４ｉ）に力を加え、回転体３を回動する。したがって、歯２ａは、曲率の大きな円形体４（４ｇ、４ｈ、４ｉ、４ｊ）の外周面に接することとなり、双方間の摩擦は低減し、歯車２の回転伝達時の摩擦損失を極力小さくすることができる。   As described above, according to the drive transmission device 1 of the present invention, when the gear 2 is rotationally driven, the teeth 2a of the gear 2 sequentially contact the circular bodies 4 (4g, 4h, 4i, 4j) of the rotating body 3. The rotating body 3 is rotated in contact. At this time, the tooth surface of each tooth 2a of the gear 2 is in contact with the outer peripheral surface of the circular body 4 (4g, 4h, 4i) while applying a force to the circular body 4 (4g, 4h, 4i), Rotate. Therefore, the tooth 2a comes into contact with the outer peripheral surface of the circular body 4 (4g, 4h, 4i, 4j) having a large curvature, the friction between both is reduced, and the friction loss at the time of rotation transmission of the gear 2 is minimized. be able to.

また、この発明の実施形態では、円形体４（４ｇ、４ｈ）をベアリング部４１を介して回転自在となるようにしたので、歯２ａと円形体４（４ｇ、４ｈ）との間の摩擦はより一層低減し、歯車２の回転伝達時の摩擦損失をさらに小さくすることができる。   In the embodiment of the present invention, since the circular body 4 (4g, 4h) can be rotated via the bearing portion 41, the friction between the teeth 2a and the circular body 4 (4g, 4h) is reduced. The friction loss at the time of transmission of the rotation of the gear 2 can be further reduced.

また、円形体４ｊにおいて、上記したように、円筒体４３ｊを止着片４２１に対して回転自在とすると、歯２ａと円形体４ｊとの間の摩擦はより一層低減し、ベアリングを用いた場合と同様に、歯車２の回転伝達時の摩擦損失をさらに小さくすることができる。   Further, in the circular body 4j, when the cylindrical body 43j is rotatable with respect to the fastening piece 421 as described above, the friction between the teeth 2a and the circular body 4j is further reduced, and a bearing is used. Similarly, the friction loss at the time of rotation transmission of the gear 2 can be further reduced.
