Abstract
Description
本発明は、動力伝達機構に関するものである。 The present invention relates to a power transmission mechanism.
従来より、摩擦車や、Vベルトなどのような摩擦力を利用した動力伝達装置や、歯車やチェーン、歯付きベルトなどの噛み合わせによる動力伝達装置が知られている。
プリンタにおける動力伝達機構では、プーリに微細な凸凹を形成したものが知られている(特許文献1参照)。
プーリとベルト摩擦によって動力を伝達している場合、油やゴミなどで伝達できるトルクが低下してしまう。それを防ぐため、張力を上げるという方法が考えられるが、それでは経年変化が大きくなってしまうので、プーリ、もしくはベルトのいずれかの摺動面に微細な凸凹をつけて解決しようとするものである。
微細な凹凸により表面積が増し油やゴミの膜が薄くなると共に、凹凸の先での圧力が増すので、油やゴミの膜を押しのけて摩擦することができる。このため張力を上げる必要がなく経年変化も少なく、動力を確実に伝達することができるというものである。
また、用紙の送りローラに微小突起を形成したものが知られている(特許文献2参照)。
高速のカラープリンタにおいて、用紙を正確に送り出すというのは非常に重要である。従って、微小突起を形成した金属製の送りローラを使用することにより、摩擦係数をあげ、ローラと用紙との間が滑ることを防ぐことができ、ゴムローラに比べ寸法精度もよいので正確に用紙を送り出すことができるというものである。
また、微小突起を形成した送りローラにかかる負荷がある程度を超えた場合は、メインモータとの間に設けられたトルクリミッターが作動し、動力を遮断する。
As a power transmission mechanism in a printer, a pulley in which fine irregularities are formed is known (see Patent Document 1).
When power is transmitted by friction between the pulley and the belt, the torque that can be transmitted by oil or dust decreases. In order to prevent this, a method of increasing the tension can be considered, but this will increase the secular change, so it is intended to solve by attaching a minute unevenness on either the sliding surface of the pulley or belt. .
The fine unevenness increases the surface area and thins the oil or dust film, and the pressure at the tip of the unevenness increases, so that the oil or dust film can be pushed and rubbed. For this reason, it is not necessary to increase the tension, the secular change is small, and the power can be reliably transmitted.
Also known is a paper feed roller in which minute protrusions are formed (see Patent Document 2).
In a high-speed color printer, it is very important to accurately feed paper. Therefore, by using a metal feed roller with minute protrusions, it is possible to increase the coefficient of friction and prevent slippage between the roller and the paper, and because the dimensional accuracy is better than that of the rubber roller, It can be sent out.
In addition, when the load applied to the feed roller on which the minute protrusions are formed exceeds a certain level, a torque limiter provided between the main motor and the power is operated to cut off the power.
以上のような従来の動力伝達機構において、摩擦力などでは伝えられる力が小さく、摩擦による発熱や摩耗が起こるという問題があった。また、歯車やチェーン、歯付きベルトなどではピッチが決まっているため、噛み合わせを考慮する必要があり、高い工作精度が必要で価格が高くなりやすいという問題があった。そして、歯が破損すると全く力を伝えられなくなるという問題があった。 In the conventional power transmission mechanism as described above, there is a problem that the force transmitted by the frictional force is small, and heat generation and wear due to friction occur. Further, since gears, chains, toothed belts, and the like have predetermined pitches, it is necessary to consider meshing, and there is a problem that high machining accuracy is required and the price is likely to increase. And when a tooth | gear was damaged, there existed a problem that power could not be transmitted at all.
特許文献1における微細な凹凸を利用した動力伝達機構は、油やゴミによる伝達トルクの低下を防ぐものであり、根本的な伝達トルクの向上を得られるものではない。従って、各種機械におけるチェーンや歯付きベルトのように大きなトルクを伝えることができないという問題がある。また、過負荷によって摺動面が滑った場合には、微細な凹凸により応力が集中するので摩耗しやすいという問題がある。
The power transmission mechanism using fine irregularities in
特許文献2における微小突起を利用した動力伝達装置は、用紙を確実に送る程度の力を伝えられるだけであり、各種機械において力のかかる動力伝達には使用できないという問題がある。また、摩擦による破損を防ぐため、トルクリミッターをつけなければならないという問題がある。
The power transmission device using the minute protrusions in
本発明の目的は、従来の摩擦車や、微小な凹凸を形成したプーリまたはベルトなどに比べてより強い力を伝え、かつ摩耗や発熱を抑えるものであり、歯車やチェーン、歯付きベルトなどのように噛み合わせを考慮する必要のない、簡単な構造で応用範囲の広い動力伝達機構を実現することである。また、過負荷でも非常に破損しにくい動力伝達機構を実現することである。 An object of the present invention is to transmit a stronger force than a conventional friction wheel, a pulley or belt having minute unevenness, and to suppress wear and heat generation, such as a gear, a chain, a toothed belt, etc. Thus, it is to realize a power transmission mechanism having a wide range of application with a simple structure that does not need to consider meshing. Another object is to realize a power transmission mechanism that is not easily damaged by overload.
本発明に係る動力伝達機構は、変形可能な棒状の微小な突起(1)を多数表面に有する動力伝達面(2)と、前記突起が横方向に引っかかるような動力伝達面(3)とから構成される。
具体的構成において、本発明に係る動力伝達機構は、互いに係合する一対の回転体から構成され、図1の如く、一方の回転体の動力伝達面(2)には、その全域に、多数の微小な突起(1)が均等若しくはほぼ均等な間隔で突設され、該突起(1)は、太さが高さ方向に同一の棒状、若しくは先端が根元よりも細い円錐状又は角錐状であって、屈曲する方向に弾性変形可能である。
又、他方の回転体の動力伝達面(3)には、その全域に、前記一方の回転体の動力伝達面(2)の突起(1)が引っかかる微小なループ(4)が均等若しくはほぼ均等な間隔で多数突設され、該ループ(4)は、屈曲する方向に弾性変形可能である。
或いは、他方の回転体の動力伝達面(3)には、その全域に、弾性変形可能な表面層が形成され、該表面層には、前記一方の回転体の動力伝達面(2)の突起(1)が侵入可能な微小な穴(9)又は凹み(10)が、均等若しくはほぼ均等な間隔で多数形成されている(図6参照)。
The power transmission mechanism according to the present invention includes a power transmission surface (2) having a large number of deformable rod-shaped projections (1) on the surface, and a power transmission surface (3) in which the projections are caught in the lateral direction. Composed.
In a specific configuration, the power transmission mechanism according to the present invention includes a pair of rotating bodies that engage with each other. As shown in FIG. The projections (1) are projected at equal or substantially equal intervals, and the projections (1) have the same rod shape in the height direction, or a cone shape or a pyramid shape whose tip is narrower than the root. Thus, it can be elastically deformed in the bending direction.
The power transmission surface (3) of the other rotating body has a minute loop (4) in which the protrusion (1) of the power transmission surface (2) of the one rotating body is hooked on the entire area. A large number of protrusions are provided at regular intervals, and the loop (4) can be elastically deformed in the bending direction.
Alternatively, an elastically deformable surface layer is formed over the entire area of the power transmission surface (3) of the other rotating body, and the protrusion of the power transmission surface (2) of the one rotating body is formed on the surface layer. A large number of minute holes (9) or recesses (10) into which (1) can enter are formed at equal or substantially equal intervals (see FIG. 6).
上記本発明の動力伝達機構において、微小な突起(1)を有する動力伝達面(2)が、この微小な突起(1)に横方向に引っかかるような動力伝達面(3)と摩擦力の働く方向に動こうとすると、多数の微小な突起(1)が引っかかり、大きな力を伝達する。
多数の微小な突起(1)に力が分散されるため強い力を伝えることができる。
過負荷がかかった場合は、微小な突起(1)が弾性変形し、引っかかりが外れるので破損しない。またこの時、次の引っかかりに引っかかったり、別の微小な突起が引っかかっていたり、摩擦することによって動力が完全に断ち切られることはない。
微小な突起(1)が方向性を持って傾いた面では、傾いている方向にのみ微小な突起(1)が引っかかる。
又、上記具体的構成においては、両回転体の動力伝達面(2)(3)が図7の如く互いに係合して動力の伝達が行なわれるが、この過程で、一方の回転体の動力伝達面(2)に突設された多数の突起(1)が順次、他方の回転体に形成されたループ(4)、穴(9)又は凹み(10)に侵入し、その後、離脱することになる。ここで、突起(1)は、太さが高さ方向に同一の棒状、若しくは先端が根元よりも細い円錐状又は角錐状に形成されているため、両回転体の回転に伴って、ループ(4)、穴(9)又は凹み(10)に対する侵入と離脱はスムーズに行なわれる。又、突起(1)がループ(4)、穴(9)又は凹み(10)に深く侵入した状態では、突起(1)の根元がループ(4)、穴(9)又は凹み(10)に係合し、該根元は先端に比べて弾性変形に大きな抵抗力を発揮するので、両回転体の外周面の接線方向、即ち動力を伝達する方向に大きな締結力が得られる。
尚、一方の動力伝達面の突起(1)と、他方の動力伝達面のループ(4)、穴(9)又は凹み(10)とは、必ずしも一対一に対応していないが、両回転体の係合面に存在する一部の突起(1)がループ(4)、穴(9)又は凹み(10)に侵入することが出来ない場合であっても、係合面に存在する他の複数の突起(1)がループ(4)、穴(9)又は凹み(10)に侵入することになるので、常に動力伝達状態が維持されることになる。
In the power transmission mechanism of the present invention described above, the power transmission surface (2) having the minute protrusion (1) acts on the power transmission surface (3) and the frictional force acting on the minute protrusion (1) in the lateral direction. When trying to move in the direction, a large number of minute protrusions (1) are caught, and a large force is transmitted.
Since the force is distributed to many minute protrusions (1), a strong force can be transmitted.
When an overload is applied, the minute protrusion (1) is elastically deformed and is not damaged because the hook is released. Also, at this time, the power is not completely cut off due to the next catch, another minute protrusion caught, or friction.
On the surface where the minute protrusion (1) is inclined with directionality, the minute protrusion (1) is caught only in the inclined direction.
In the above specific configuration, the power transmission surfaces (2) and (3) of both rotating bodies are engaged with each other as shown in FIG. 7, and the power is transmitted. In this process, the power of one rotating body is transmitted. A number of protrusions (1) projecting from the transmission surface (2) sequentially enter the loop (4), hole (9) or recess (10) formed on the other rotating body, and then disengage. become. Here, the protrusion (1) is formed in the same rod shape in the height direction, or in the shape of a cone or pyramid whose tip is thinner than the base, so that the loop ( 4) Intrusion and withdrawal from the hole (9) or the recess (10) are performed smoothly. In addition, when the protrusion (1) penetrates deeply into the loop (4), the hole (9) or the recess (10), the root of the protrusion (1) enters the loop (4), the hole (9) or the recess (10). Engagement and the base exerts a greater resistance to elastic deformation than the tip, so that a large fastening force can be obtained in the tangential direction of the outer peripheral surfaces of both rotating bodies, that is, in the direction of transmitting power.
The protrusion (1) on one power transmission surface and the loop (4), hole (9) or recess (10) on the other power transmission surface do not necessarily correspond one-to-one, but both rotating bodies Even if some protrusions (1) existing on the engagement surface cannot enter the loop (4), the hole (9) or the recess (10), Since the plurality of protrusions (1) enter the loop (4), the hole (9) or the recess (10), the power transmission state is always maintained.
本発明に係る動力伝達機構によれば、摩擦による力の伝達を従来よりも強くすることができ、摩擦による発熱や摩耗を防ぐことができる。歯車などのように噛み合わせがないので任意の形にすることができ使い勝手がよい。また構造が簡単で小型、軽量にでき、工作精度も必要でなく安価にできる。また過負荷がかかっても微小な突起(1)が弾性変形し、引っかかりが外れるだけなので破損せず、本発明自体が一定以上の負荷を伝えないトルクリミッターの働きをする。 According to the power transmission mechanism of the present invention, transmission of force due to friction can be made stronger than before, and heat generation and wear due to friction can be prevented. Since there is no meshing like a gear, it can be made in any shape and it is easy to use. In addition, the structure is simple, can be made small and light, and the machining accuracy is not required and can be made inexpensive. Further, even if an overload is applied, the minute protrusion (1) is elastically deformed, and is not broken because it is only released from being caught, and the present invention itself functions as a torque limiter that does not transmit a load above a certain level.
以下、本発明をベルト駆動装置に実施した形態について、図面に沿って具体的に説明する。
本発明に係るベルト駆動装置は、図2に示す構成を有し、ホイール(5)の外周面は、図8の如く、太さが高さ方向に同一の棒状(11)、若しくは先端が根元よりも細い円錐状(12)又は角錐状(13)であって、屈曲する方向に弾性変形可能な微小な突起(1)が均等な間隔で分布する様に多数突設された動力伝達面(2)にし、ベルト(6)の内側の面は、前記動力伝達面(2)の突起(1)に引っかかる、屈曲する方向に弾性変形可能な微小なループ(4)が均等な間隔で分布するように多数突設された動力伝達面(3)にする(図1参照)。
多数の微小な突起(1)が微小なループ(4)に引っかかり、動力を伝達する。多数の突起(1)に力が分散されるため強い力を伝えることができる。過負荷がかかった場合には、微小な突起(1)が弾性変形し引っかかりが外れるので破損しない。
摩擦ではなく、物理的に突起が引っかかって力を伝えるため、強い動力を伝えることができる。また発熱や摩耗も少なく油にも強い。垂直抗力を得る必要がないので張力が少なくてすみ、保持が容易である。張力が少なくてすむのでベルトが薄くでき、Vベルトやチェーンに比べ非常に軽量にできる。構造が簡単で、噛み合わせを考える必要もないので小型化が容易である。また、過負荷がかかった場合は本発明の動力伝達機構自体がトルクリミッターとして働き、装置の破壊を防ぐことができる。このとき伝達される力は全くなくなってしまうわけではなく、過負荷以下の力を伝達しつづけることができ、本発明自体も破損しない。伝達できる力が、前記動力伝達面(2)と動力伝達面(3)の係合する面積と比例しているため、計算も容易で、設計しやすく使い勝手がよい。
Hereinafter, embodiments of the present invention applied to a belt drive device will be described in detail with reference to the drawings.
The belt driving device according to the present invention has the configuration shown in FIG. 2, and the outer peripheral surface of the wheel (5) has the same rod shape (11) in the height direction as shown in FIG. A narrower cone shape (12) or a pyramid shape (13), and a power transmission surface in which a large number of projections (1) elastically deformable in the bending direction are distributed at equal intervals ( 2), on the inner surface of the belt (6), minute loops (4) that are hooked on the protrusions (1) of the power transmission surface (2) and elastically deformable in the bending direction are distributed at equal intervals. Thus, the power transmission surface (3) is provided with a large number of protrusions (see FIG. 1).
A large number of minute protrusions (1) are caught in the minute loop (4) to transmit power. Since the force is distributed to a number of protrusions (1), a strong force can be transmitted. If an overload is applied, the minute protrusion (1) will be elastically deformed and will not be damaged.
Strong force can be transmitted because the protrusion is physically caught and transmitted, not friction. In addition, it generates little heat and wear and is resistant to oil. Since there is no need to obtain vertical drag, tension is low and holding is easy. Since less tension is required, the belt can be made thinner and much lighter than V belts and chains. Since the structure is simple and it is not necessary to consider meshing, it is easy to reduce the size. Further, when an overload is applied, the power transmission mechanism itself of the present invention functions as a torque limiter and can prevent the apparatus from being destroyed. At this time, the transmitted force is not lost at all, and the force below the overload can be continuously transmitted, and the present invention itself is not damaged. Since the force that can be transmitted is proportional to the area where the power transmission surface (2) and the power transmission surface (3) are engaged, the calculation is easy, the design is easy, and the usability is good.
以下、本発明を摩擦車に実施した形態について、図面に沿って具体的に説明する。
本発明に係る摩擦車は、図3に示す構成を有し、2つのホイール(5)のいずれかのホイール(5)の外周面を、前記実施形態と同様の微小な突起(1)が均等な間隔で分布する様に多数突設された動力伝達面(2)にし、相手側のホイール(5)の外周面を前記動力伝達面(2)の突起(1)に引っかかる、前記実施形態と同様の微小なループ(4)が均等な間隔で分布するように多数突設された動力伝達面(3)にする(図1参照)。
多数の微小な突起(1)が微小なループ(4)に引っかかり、動力を伝達する。多数の突起(1)に力が分散されるため強い力を伝えることができる。過負荷がかかった場合には、微小な突起(1)が弾性変形し引っかかりが外れるので破損しない。
摩擦ではなく、物理的に突起が引っかかって力を伝えるため、強い動力を伝えることができる。また発熱や摩耗も少なく油にも強い。垂直抗力を得る必要がないので歯車同様軸間距離を保っていればよく、扱いやすい。また、ホイールの外周に力がかかるだけのため、軽量にできる。構造が簡単で小型にできるのでマイクロマシンなどにも応用が可能である。図3に示すような内接するものに関しては、歯車のような噛み合わせがないので内周と外周の差を小さくすることができ、差動式減速機などでは大きな減速比が得られる。前記実施形態と同様に、過負荷がかかった時にはトルクリミッターとして働き、破壊を防ぐことができる。また、伝達できる力が、前記動力伝達面(2)と動力伝達面(3)の係合する面積と比例しているため、計算も容易で、設計しやすく使い勝手がよい。
Hereinafter, embodiments of the present invention applied to a friction wheel will be specifically described with reference to the drawings.
The friction wheel according to the present invention has the configuration shown in FIG. 3, and the minute projections (1) similar to those of the above-described embodiment are evenly provided on the outer peripheral surface of one of the two wheels (5). The power transmission surface (2) projecting so as to be distributed at a certain interval, and the outer peripheral surface of the other wheel (5) is hooked on the protrusion (1) of the power transmission surface (2). The power transmission surface (3) is provided in a large number so as to distribute similar minute loops (4) at equal intervals (see FIG. 1).
A large number of minute protrusions (1) are caught in the minute loop (4) to transmit power. Since the force is distributed to a number of protrusions (1), a strong force can be transmitted. When an overload is applied, the minute protrusion (1) is elastically deformed and is not caught and is not damaged.
Strong force can be transmitted because the protrusion is physically caught and transmitted, not friction. In addition, it generates little heat and wear and is resistant to oil. Since there is no need to obtain vertical drag, it is only necessary to maintain an inter-axis distance like a gear, and it is easy to handle. Moreover, since force is only applied to the outer periphery of the wheel, the weight can be reduced. Since the structure is simple and small, it can be applied to micromachines. With respect to the inscribed one as shown in FIG. 3, since there is no meshing like a gear, the difference between the inner circumference and the outer circumference can be reduced, and a large reduction ratio can be obtained with a differential reduction gear or the like. Similar to the above embodiment, when an overload is applied, it functions as a torque limiter and can prevent destruction. Further, since the force that can be transmitted is proportional to the area where the power transmission surface (2) and the power transmission surface (3) are engaged, the calculation is easy, the design is easy, and the usability is good.
以下、本発明を無段変速機に実施した形態について説明する。
本発明に係る無段変速機は、摩擦によって動力を伝える方式の無段変速機の、摩擦する面の原動体側と従動体側のいずれかを、前記実施形態と同様の微小な突起(1)が均等な間隔で分布するように多数突設された動力伝達面(2)にし、相手側を前記動力伝達面(2)の突起(1)に引っかかる、前記実施形態と同様の微小なループ(4)が均等な間隔で分布するように多数突設された動力伝達面(3)にする。
多数の微小な突起(1)が微小なループ(4)に引っかかり、動力を伝達する。多数の突起(1)に力が分散されるため強い力を伝えることができる。過負荷がかかった場合には、微小な突起(1)が弾性変形し引っかかりが外れるので破損しない。
摩擦ではなく、物理的に突起が引っかかって力を伝えるため、強い動力を伝えることができる。また、油にも強い。摩擦ではないので、摩擦力を大きくするような特殊な油を使う必要もなく、垂直抗力を得る必要もないので高い工作精度が必要でなくなり安価にできる。また伝えられる力が大きいので小型化、軽量化が可能である。前記実施形態と同様に、過負荷がかかった時にはトルクリミッターとして働き、破壊を防ぐことができる。また、伝達できる力が、前記動力伝達面(2)と動力伝達面(3)の係合する面積と比例しているため、計算も容易で、設計しやすく使い勝手がよい。

Strong force can be transmitted because the protrusion is physically caught and transmitted, not friction. Also resistant to oil. Since it is not friction, it is not necessary to use special oil that increases the frictional force, and it is not necessary to obtain vertical drag, so high work accuracy is not required and the cost can be reduced. In addition, since the transmitted force is large, it is possible to reduce the size and weight. Similar to the above embodiment, when an overload is applied, it functions as a torque limiter and can prevent destruction. Further, since the force that can be transmitted is proportional to the area where the power transmission surface (2) and the power transmission surface (3) are engaged, the calculation is easy, the design is easy, and the usability is good.

或いは、他方の回転体の動力伝達面(3)には、その全域に、弾性変形可能な表面層が形成され、該表面層には、前記一方の回転体の動力伝達面(2)の突起(1)が侵入可能な穴(9)又は凹み(10)が、均等もしくはほぼ均等な間隔で多数形成されている。
The power transmission mechanism according to the present invention includes a power transmission surface (2) having a large number of linear protrusions (1) that are perpendicular to the power transmission surface and elastically deformable on the surface, and the protrusions are displaced in the direction of displacement between the power transmission surfaces. It consists of a power transmission surface (3) with a number of loops (4) or holes (9) or indentations (10) that hook against it.
In a specific configuration, the power transmission mechanism according to the present invention includes a pair of rotating bodies that engage with each other, and the power transmission surface (2) of one of the rotating bodies has a large number of protrusions (1) throughout the entire area. Are projected at equal or substantially equal intervals, and the protrusion (1) has the same rod shape in the height direction, or a conical shape or a pyramid shape whose tip is narrower than the root, and in the bending direction. Elastic deformation is possible.
Further, the power transmission surface (3) of the other rotating body has a loop (4) in which the projection (1) of the power transmission surface (2) of the one rotating body is hooked at an equal or substantially equal interval. The loop (4) is elastically deformable in the bending direction.
Alternatively, an elastically deformable surface layer is formed on the entire power transmission surface (3) of the other rotating body, and a protrusion of the power transmission surface (2) of the one rotating body is formed on the surface layer. A large number of holes (9) or recesses (10) into which (1) can enter are formed at equal or substantially equal intervals.
上記本発明の動力伝達機構において、動力伝達面(2)が、動力伝達面(3)とずれ方向に動こうとすると、多数の突起(1)とループ(4)又は穴(9)又は凹み(10)が多数引っかかる。
多数の突起(1)とループ(4)又は穴(9)又は凹み(10)に力が分散されるため強い力を伝えることができる。
過負荷がかかった場合は、突起(1)が弾性変形し、引っ掛かりが外れるので破損しない。またこの時、次の引っ掛かりに引っかかったり、別の突起が引っ掛かっていたり、摩擦することによって動力が完全に断ち切られることはない。
又、上記具体的構成においては、両回転体の動力伝達面(2)(3)が互いに係合して動力の伝達が行なわれるが、この過程で、一方の回転体の動力伝達面(2)に突設された多数の突起(1)が順次、他方の回転体に形成されたループ(4)、穴(9)又は凹み(10)に侵入し、その後、離脱することになる。ここで、突起(1)は、太さが高さ方向に同一の棒状、もしくは先端が根元よりも細い円錐状又は角錐状に形成されているため、両回転体の回転に伴って、ループ(4)、穴(9)又は凹み(10)に対する侵入と離脱はスムーズに行なわれる。又、突起(1)がループ(4)、穴(9)又は凹み(10)に深く侵入した状態では、突起(1)の根元がループ(4)、穴(9)又は凹み(10)に係合し、該根元は先端に比べて弾性変形に大きな抵抗力を発揮するので、両回転体の外周面の接線方向、即ち動力を伝達する方向に大きな締結力が得られる。
尚、一方の動力伝達面の突起(1)と、他方の動力伝達面のループ(4)又は穴(9)又は凹み(10)とは、必ずしも一対一に対応してないが、両回転体の係合面に存在する一部の突起(1)がループ(4)又は穴(9)又は凹み(10)に侵入することが出来ない場合であっても、係合面に存在する他の複数の突起(1)がループ(4)又は穴(9)又は凹み(10)に侵入することになるので、常に動力伝達状態が維持されることになる。
In the power transmission mechanism of the present invention described above, when the power transmission surface (2) tries to move in a direction shifted from the power transmission surface (3) , a large number of projections (1) and loops (4) or holes (9) or dents. (10) is caught many times .
Since the force is distributed to a large number of protrusions (1) and loops (4) or holes (9) or recesses (10) , a strong force can be transmitted.
When an overload is applied, the protrusion (1) is elastically deformed and is not damaged because the hook is released. Also, at this time, the power is not completely cut off by being caught by the next catch, by being caught by another protrusion, or by friction.
In the above-described specific configuration, the power transmission surfaces (2) and (3) of both rotating bodies are engaged with each other to transmit power. In this process, the power transmission surfaces (2 ) Project in succession into the loop (4), the hole (9) or the recess (10) formed on the other rotating body, and then disengage. Here, since the protrusion (1) is formed in a rod shape having the same thickness in the height direction, or a conical shape or a pyramid shape whose tip is thinner than the root, the loop ( 4) Intrusion and removal from the hole (9) or dent (10) are performed smoothly. In addition, when the protrusion (1) has penetrated deeply into the loop (4), the hole (9) or the recess (10), the root of the protrusion (1) enters the loop (4), the hole (9) or the recess (10). Engagement and the base exerts a greater resistance to elastic deformation than the tip, so that a large fastening force can be obtained in the tangential direction of the outer peripheral surfaces of both rotating bodies, that is, in the direction of transmitting power.
Note that the protrusion (1) on one power transmission surface and the loop (4), hole (9), or recess (10) on the other power transmission surface do not necessarily correspond one-to-one. Even if some of the protrusions (1) present on the engaging surface cannot enter the loop (4) or the hole (9) or the recess (10), Since the plurality of protrusions (1) enter the loop (4) or the hole (9) or the recess (10), the power transmission state is always maintained.
本発明に係る動力伝達機構によれば、従来の摩擦による動力伝達よりも強い力を伝えることができ、摩擦による発熱や摩耗を防ぐとこができる。歯車などのように噛み合わせがないので任意の形にすることができ使い勝手がよい。また構造が簡単で小型、軽量にでき、工作精度も必要でなく安価にできる。また過負荷がかかっても突起(1)が弾性変形し、引っ掛かりが外れるだけなので破損せず、本発明自体が一定以上の負荷を伝えないトルクリミッターの働きをする。 According to the power transmission mechanism according to the present invention, it is possible to transmit a force stronger than the conventional power transmission by friction, and it is possible to prevent heat generation and wear due to friction. Since there is no meshing like a gear, it can be made in any shape and it is easy to use. In addition, the structure is simple and can be made small and light, and the machining accuracy is not required and the cost can be reduced. Further, even if an overload is applied, the protrusion (1) is elastically deformed and is not broken because it is simply disengaged, and the present invention itself functions as a torque limiter that does not transmit a load above a certain level.
以下、本発明をベルト駆動装置に実施した形態について、図面に沿って具体的に説明する。
本発明に係るベルト駆動装置は、図2示す如くホイール(5)の外周面は、太さが高さ方向に同一の棒状、若しくは先端が根元よりも細い円錐状又は角錐状であって、屈曲する方向に弾性変形可能な突起(1)が均等もしくはほぼ均等な間隔で分布する様に多数突設された動力伝達面(2)にし、ベルト(6)の内側の面は、前記動力伝達面(2)の突起(1)に引っ掛かる、屈曲する方向に弾性変形可能なループ(4)が均等もしくはほぼ均等な間隔で分布するように多数突設された動力伝達面(3)にする。
多数の突起(1)がループ(4)に引っ掛かり、動力を伝達する。多数の突起(1)に力が分散されるため強い力を伝えることができる。過負荷がかかった場合には、突起(1)が弾性変形し引っ掛かりが外れるので破損しない。
摩擦ではなく、物理的に突起が引っ掛かって力を伝えるため、強い動力を伝えることができる。また発熱や摩耗も少なく油にも強い。垂直抗力を得る必要がないので張力が少なくてすみ、保持が容易である。張力が少なくてすむのでベルトを薄くでき、Vベルトやチェーンに比べ非常に軽量にできる。構造が簡単で、噛み合わせを考える必要もないので小型化が容易である。また、過負荷がかかった場合は本発明の動力伝達機構自体がトルクリミッターとして働き、装置の破壊を防ぐことができる。このとき伝達される力は全くなくなってしまうわけではなく、過負荷以下の力を伝達しつづけることができ、本発明自体も破損しない。伝達できる力が、前記動力伝達面(2)と動力伝達面(3)の係合する面積と比例しているため、計算も容易で、設計しやすく使い勝手がよい。
Hereinafter, embodiments of the present invention applied to a belt drive device will be described in detail with reference to the drawings.
In the belt drive device according to the present invention, as shown in FIG. 2, the outer peripheral surface of the wheel (5) is a rod having the same thickness in the height direction, or a cone or pyramid with a tip thinner than the base, and is bent. The power transmission surface (2) is provided with a large number of protrusions (1) that can be elastically deformed in the direction to be distributed at equal or substantially equal intervals, and the inner surface of the belt (6) is the power transmission surface. The power transmission surface (3) is provided with a large number of protrusions so that the loops (4) that are hooked on the protrusions (1) and can be elastically deformed in the bending direction are evenly or substantially evenly distributed.
A number of protrusions (1) are caught on the loop (4) and transmit power. Since the force is distributed to a large number of protrusions (1), a strong force can be transmitted. When an overload is applied, the protrusion (1) is elastically deformed and the hook is released, so that it is not damaged.
Strong power can be transmitted because the protrusion is physically caught and transmitted, not friction. In addition, it generates little heat and wear and is resistant to oil. Since there is no need to obtain vertical drag, tension is low and holding is easy. Since less tension is required, the belt can be made thinner and much lighter than a V-belt or chain. Since the structure is simple and it is not necessary to consider meshing, it is easy to reduce the size. Further, when an overload is applied, the power transmission mechanism itself of the present invention functions as a torque limiter and can prevent the apparatus from being destroyed. At this time, the transmitted force is not lost at all, and the force below the overload can be continuously transmitted, and the present invention itself is not damaged. Since the force that can be transmitted is proportional to the area of engagement between the power transmission surface (2) and the power transmission surface (3), the calculation is easy, the design is easy, and the usability is good.
以下、本発明を摩擦車に実施した形態について、図面に沿って具体的に説明する。
本発明に係る摩擦車は、図3に示す如く、2つのホイール(5)のいずれかのホイール(5)の外周面を、前記実施形態と同様の突起(1)が均等もしくはほぼ均等な間隔で分布する様に多数突設された動力伝達面(2)にし、相手側のホイール(5)の外周面を前記動力伝達面(2)の突起(1)に引っ掛かる、前記実施形態と同様のループ(4)が均等もしくはほぼ均等な間隔で分布するように多数突設された動力伝達面(3)にする。
多数の突起(1)がループ(4)に引っ掛かり、動力を伝達する。多数の突起(1)に力が分散されるため強い力を伝えることができる。過負荷がかかった場合には、突起(1)が弾性変形し引っ掛かりが外れるので破損しない。
摩擦ではなく、物理的に突起が引っ掛かって力を伝えるため、強い動力を伝えることができる。また発熱や摩耗も少なく油にも強い。垂直抗力を得る必要がないので歯車同様軸間距離を保っていればよく、扱いやすい。また、ホイールの外周に力がかかるだけのため、軽量にできる。構造が簡単で小型にできるのでマイクロマシンなどにも応用が可能である。図3に示すような内接するものに関しては、歯車のような噛み合わせがないので内周と外周の差を小さくすることができ、差動式減速機などでは大きな減速比が得られる。前記実施形態と同様に、過負荷がかかった時にはトルクリミッターとして働き、破壊を防ぐことができる。また、伝達できる力が、前記動力伝達面(2)と動力伝達面(3)の係合する面積と比例しているため、計算も容易で、設計しやすく使い勝手がよい。

When an overload is applied, the protrusion (1) is elastically deformed and the catch is released, so that it is not damaged.
Strong power can be transmitted because the protrusion is physically caught and transmitted, not friction. In addition, it generates little heat and wear and is resistant to oil. Since there is no need to obtain vertical drag, it is only necessary to maintain an inter-axis distance like a gear, and it is easy to handle. Moreover, since force is only applied to the outer periphery of the wheel, the weight can be reduced. Since the structure is simple and small, it can be applied to micromachines. With respect to the inscribed one as shown in FIG. 3, since there is no meshing like a gear, the difference between the inner circumference and the outer circumference can be reduced, and a large reduction ratio can be obtained with a differential reduction gear or the like. Similar to the above embodiment, when an overload is applied, it functions as a torque limiter and can prevent destruction. Further, since the force that can be transmitted is proportional to the area where the power transmission surface (2) and the power transmission surface (3) are engaged, the calculation is easy, the design is easy, and the usability is good.
以下、本発明を無段変速機に実施した形態について説明する。
