Description

本発明は、駆動源が発生した駆動力を回転体に伝達する駆動力伝達装置及び駆動力伝達システムに関する。   The present invention relates to a driving force transmission device and a driving force transmission system that transmit a driving force generated by a driving source to a rotating body.

従来、回転体の回転数を変更する方法として、例えば、モータの回転数をインバーターによって制御する方法が開示されている（特許文献１）。しかしながら、インバーターによる回転数制御は、回転数の変化率が小さい場合に用いられるものであって、回転数の変化率が大きい場合には、通常のインバーターによる制御を使用することはなかった。   Conventionally, as a method of changing the rotation speed of a rotating body, for example, a method of controlling the rotation speed of a motor by an inverter has been disclosed (Patent Document 1). However, the rotation speed control by the inverter is used when the change rate of the rotation speed is small, and when the change rate of the rotation speed is large, the normal control by the inverter is not used.

特開平８−１２６３７６号公報JP-A-8-126376

また、サーボモータの駆動力により減速機を介して回転体を回転させるシステムにおいて、回転体の速度に応じてインバーターを用いて、サーボモータを制御する方法が考えられる。しかしながら、サーボモータは高額であり、さらにインバーターとサーボモータのための２つの制御装置が必要となるため、より高額なシステムとなってしまう。   Further, in a system in which a rotating body is rotated by a driving force of a servomotor via a speed reducer, a method of controlling the servomotor by using an inverter according to the speed of the rotating body can be considered. However, the servo motor is expensive and requires two control devices for the inverter and the servo motor, resulting in a more expensive system.

本発明は上記課題を解決し、簡単な構造で安価に形成することができ、効率良く回転数を切り替えることが可能な駆動力伝達装置及び駆動力伝達システムを提供することを目的とする。   SUMMARY OF THE INVENTION It is an object of the present invention to provide a driving force transmission device and a driving force transmission system which can solve the above problems, can be formed at a low cost with a simple structure, and can efficiently switch the rotation speed.

以下、図面を参照して本発明にかかる駆動力伝達システム１０の実施形態を説明する。   Hereinafter, an embodiment of a driving force transmission system 10 according to the present invention will be described with reference to the drawings.

図１は、第１実施形態の駆動力伝達装置１及び駆動力伝達システム１０の一部を示す。図２は、図１のII−II断面を含む第１実施形態の駆動力伝達システム１０を示す。   FIG. 1 shows a part of the driving force transmission device 1 and the driving force transmission system 10 of the first embodiment. FIG. 2 shows the driving force transmission system 10 of the first embodiment including the II-II cross section of FIG. 1.

第１実施形態の回転体２の駆動力伝達システム１０は、駆動力伝達装置１と、回転体２と、第１駆動源としての第１モータ３と、第２駆動源としての第２モータ４と、を備える。駆動力伝達装置１は、第１モータ３及び第２モータ４の駆動力を回転体２に伝達する。第１モータ３及び駆動力伝達装置１は、回転体２が１０〜２０ｒｐｍ程度で回転するように設定されると好ましい。第２モータ４及び駆動力伝達装置１は、回転体２が５〜２０ｒｐｈ程度で回転するように設定されると好ましい。回転体２としては、空調機に用いるデシカントローター等のローターが好ましい。   A driving force transmission system 10 for a rotating body 2 according to the first embodiment includes a driving force transmitting device 1, a rotating body 2, a first motor 3 as a first driving source, and a second motor 4 as a second driving source. And The driving force transmission device 1 transmits the driving forces of the first motor 3 and the second motor 4 to the rotating body 2. The first motor 3 and the driving force transmission device 1 are preferably set so that the rotating body 2 rotates at about 10 to 20 rpm. The second motor 4 and the driving force transmission device 1 are preferably set so that the rotating body 2 rotates at about 5 to 20 rph. As the rotating body 2, a rotor such as a desiccant rotor used for an air conditioner is preferable.

第１モータ３と第２モータ４は、同時に駆動しないことが好ましい。したがって、駆動力伝達装置１は、第１モータ３の駆動力のみを回転体２に伝達する状態と、第２モータ４の駆動力のみを回転体２に伝達する状態と、を切り替える。   It is preferable that the first motor 3 and the second motor 4 are not driven simultaneously. Therefore, the driving force transmission device 1 switches between a state in which only the driving force of the first motor 3 is transmitted to the rotating body 2 and a state in which only the driving force of the second motor 4 is transmitted to the rotating body 2.

第１モータ３の回転数は、第２モータ４の回転数と異なる。以下の実施形態では、第１モータ３は、第２モータ４より高速に回転するものとする。したがって、回転体２は、第１モータ３の駆動力が駆動力伝達装置１によって伝達された場合の方が、第２モータ４の駆動力が駆動力伝達装置１によって伝達された場合よりも、高速に回転する。   The rotation speed of the first motor 3 is different from the rotation speed of the second motor 4. In the following embodiments, the first motor 3 rotates faster than the second motor 4. Therefore, in the rotating body 2, the case where the driving force of the first motor 3 is transmitted by the driving force transmission device 1 is more than the case where the driving force of the second motor 4 is transmitted by the driving force transmission device 1. Rotate at high speed.

And has a portion 5c and rotates about the axis C. In the present embodiment, the driving force is input from the first motor 3 to the first base end portion 5a. The first intermediate portion 5b has a diameter smaller than that of the first base end portion 5a, and is supported by the case 91 of the support portion 9 on the first base end portion 5a side so as to be rotatable about the axis C via the input bearing 92. , And is connected to the first cam clutch 50 on the side of the first tip 5c.

And a transmission portion 73 that transmits the driving force to the body 2. In the present embodiment, the clutch connecting portion 71 is formed in a cylindrical shape. The disk portion 72 is composed of a sprocket, a pulley or the like integrally attached to the outer periphery of the clutch connecting portion 71 by welding or the like. The transmission unit 73 is composed of a chain, a belt, or the like.

第１カムクラッチ５０は、第１入力部５に連結された第１内輪５１と、出力部７に連結された第１外輪５２と、第１内輪５１の外周側の両端及び第１外輪５２の内周側の両端に組み付けられる第１カムクラッチ用ベアリング５３と、第１内輪５１から第１外輪５２への動力の伝達を接続又は切離する複数の第１カム５４と、複数の第１カム５４が所定の角度で傾斜するように付勢する環状の第１スプリング５５と、を有する。   The first cam clutch 50 includes a first inner ring 51 connected to the first input unit 5, a first outer ring 52 connected to the output unit 7, both outer peripheral sides of the first inner ring 51, and the first outer ring 52. A first cam clutch bearing 53 assembled to both ends on the inner peripheral side, a plurality of first cams 54 for connecting or disconnecting transmission of power from the first inner ring 51 to the first outer ring 52, and a plurality of first cams 54 has an annular first spring 55 that biases 54 to incline at a predetermined angle.

第１内輪５１は、その内周に第１入力部５の外周が嵌め込まれる。そして、第１入力部５と第１内輪５１は一体に回転する。第１外輪５２は、クラッチ連結部７１の内周に嵌め込まれる。そして、第１外輪５２とクラッチ連結部７１は一体に回転する。   The outer circumference of the first input portion 5 is fitted to the inner circumference of the first inner ring 51. Then, the first input unit 5 and the first inner ring 51 rotate integrally. The first outer ring 52 is fitted on the inner circumference of the clutch connecting portion 71. Then, the first outer ring 52 and the clutch connecting portion 71 rotate integrally.

第２カムクラッチ６０は、第２入力部６に連結された第２内輪６１と、出力部７に連結された第２外輪６２と、第２内輪６１の外周側の両端及び第２外輪６２の内周側の両端に組み付けられる第２カムクラッチ用ベアリング６３と、第２内輪６１から第２外輪６２への動力の伝達を接続又は切離する複数の第２カム６４と、複数の第２カム６４が所定の角度で傾斜するように付勢する環状の第２スプリング６５と、を有する。   The second cam clutch 60 includes a second inner ring 61 connected to the second input unit 6, a second outer ring 62 connected to the output unit 7, both ends on the outer peripheral side of the second inner ring 61 and the second outer ring 62. A second cam clutch bearing 63 assembled to both ends on the inner peripheral side, a plurality of second cams 64 for connecting or disconnecting transmission of power from the second inner ring 61 to the second outer ring 62, and a plurality of second cams An annular second spring 65 that biases 64 to incline at a predetermined angle.

スリーブ８は、第１入力部５と第２入力部６をそれぞれ相対回転可能に支持する。したがって、第１入力部５が回転してもスリーブ８は回転せず、第２入力部６が回転してもスリーブ８は回転しない。スリーブ８は、第１入力部５と第２入力部６の回転中心が軸Ｃと重なるように第１入力部５と第２入力部６を支持する。スリーブ８を用いることで、第１入力部５と第２入力部６の回転中心と軸Ｃが一直線上になり、カムクラッチの偏芯による動作不能を防止することが可能となる。   The sleeve 8 supports the first input unit 5 and the second input unit 6 so as to be rotatable relative to each other.

The first cam 54 makes contact with the first inner ring 51 at the first inner ring contact portion 54a and makes contact with the first outer ring 52 at the first outer ring contact portion 54b. In a cross section orthogonal to the axis C shown in FIG. 1, a line A passing through the first inner ring contact portion 54a and the first outer ring contact portion 54b is a line passing through the central axes of the first inner ring 51 and the first outer ring 52. Tilt with respect to B. That is, the line A and the line B are in a state of being deviated by a predetermined angle.

第１カム５４は、軸方向の両端に第１内輪５１側が切り欠かれた段部５４ｃが形成される。段部５４ｃには、第１スプリング５５の外周側が当接する。そして、第１スプリング５５は、第１カム５４を図３の矢印Ｆで示す方向に付勢する。   The first cam 54 has stepped portions 54c formed by cutting out the first inner ring 51 side at both axial ends. The outer peripheral side of the first spring 55 contacts the step portion 54c. Then, the first spring 55 biases the first cam 54 in the direction indicated by the arrow F in FIG.

次に、駆動力伝達装置１の作動について説明する。ここでは、第１モータ３が駆動状態、第２モータ４が非駆動状態の場合について説明する。   Next, the operation of the driving force transmission device 1 will be described. Here, the case where the first motor 3 is in the driving state and the second motor 4 is in the non-driving state will be described.

図４は、第１実施形態の駆動力伝達装置１の第１カム５４の作動状態を示す。   FIG. 4 shows an operating state of the first cam 54 of the driving force transmission device 1 according to the first embodiment.

第１モータ３が駆動すると、駆動力伝達装置１の第１入力部５が回転し、第１内輪５１が回転する。第１内輪５１が図４に示した黒塗り矢印Ｄ１の方向に回転すると、第１カム５４は即座に回転し、第１内輪５１及び第１外輪５２と噛み合う。したがって、第１内輪５１、第１カム５４、第１外輪５２及び出力部７のクラッチ連結部７１は、一体に黒塗り矢印Ｄ２の方向に回転する。   When the first motor 3 is driven, the first input portion 5 of the driving force transmission device 1 rotates and the first inner ring 51 rotates. When the first inner ring 51 rotates in the direction of the black arrow D1 shown in FIG. 4, the first cam 54 immediately rotates and meshes with the first inner ring 51 and the first outer ring 52. Therefore, the first inner ring 51, the first cam 54, the first outer ring 52, and the clutch connecting part 71 of the output part 7 rotate integrally in the direction of the black arrow D2.

図５は、第１実施形態の駆動力伝達装置１の第２カム６４の非作動状態を示す。   FIG. 5 shows a non-operating state of the second cam 64 of the driving force transmission device 1 of the first embodiment.

図４の状態で出力部７のクラッチ連結部７１が回転すると、図５に示す白塗り矢印の方向に第２外輪６２が回転する。第２外輪６２が図５に示した白塗り矢印Ｄ３の方向に回転すると、第２カム６４は即座に回転し、第２外輪６２から離間する。したがって、第２外輪６２が空転し、第２内輪６１は回転しない。   When the clutch connecting portion 71 of the output portion 7 rotates in the state of FIG. 4, the second outer ring 62 rotates in the direction of the white arrow shown in FIG. When the second outer ring 62 rotates in the direction of the white arrow D3 shown in FIG. 5, the second cam 64 immediately rotates and separates from the second outer ring 62. Therefore, the second outer ring 62 idles and the second inner ring 61 does not rotate.

図６は、第１モータ３が作動状態の時の第１実施形態の駆動力伝達装置１の動力伝達を示す。   FIG. 6 shows the power transmission of the driving force transmission device 1 of the first embodiment when the first motor 3 is in the operating state.

第１カム５４は、第１内輪５１から第１外輪５２への動力の伝達を接続する。その結果、図１に示した第１モータ３の駆動力が駆動力伝達装置１を介して図１に示した回転体２に伝達される。すなわち、図１に示した第１モータ３が回転すると、第１入力部５、第１内輪５１、第１カム５４、第１外輪５２、クラッチ連結部７１及び円板部７２が回転し、伝達部７３を移動させる。そして、伝達部７３の移動により、図１に示した回転体２が回転する。   The first cam 54 connects the transmission of power from the first inner ring 51 to the first outer ring 52. As a result, the driving force of the first motor 3 shown in FIG. 1 is transmitted to the rotating body 2 shown in FIG. 1 via the driving force transmission device 1. That is, when the first motor 3 shown in FIG. 1 rotates, the first input portion 5, the first inner ring 51, the first cam 54, the first outer ring 52, the clutch connecting portion 71, and the disc portion 72 rotate and transmit. The part 73 is moved. Then, the rotating body 2 shown in FIG. 1 is rotated by the movement of the transmitting portion 73.

しかしながら、第２カム６４は、第２外輪６２から第２内輪６１への動力の伝達を切断する。その結果、図１に示した第１モータ３の駆動力は駆動力伝達装置１を介して図１に示した第２モータ４へは伝達されない。すなわち、クラッチ連結部７１の回転により、第２外輪６２は回転するが、第２内輪６１及び第２入力部６が回転することはない。   However, the second cam 64 disconnects the transmission of power from the second outer ring 62 to the second inner ring 61. As a result, the driving force of the first motor 3 shown in FIG. 1 is not transmitted to the second motor 4 shown in FIG. 1 via the driving force transmission device 1. That is, the second outer ring 62 is rotated by the rotation of the clutch connecting part 71, but the second inner ring 61 and the second input part 6 are not rotated.

図７は、第２モータ４が作動状態の時の第１実施形態の駆動力伝達装置１の動力伝達を示す。   FIG. 7 shows the power transmission of the driving force transmission device 1 of the first embodiment when the second motor 4 is in the operating state.

図４〜図６では、第１モータ３が駆動状態、第２モータ４が非駆動状態の場合について説明した。第１モータ３が非駆動状態、第２モータ４が駆動状態の場合については、図７に示すように、第１カムクラッチ５０と第２カムクラッチ６０の作動状態が、図６に示した作動状態とは逆になる。図６に示した第１カムクラッチ５０と第２カムクラッチ６０を反対にすればよいだけなので、具体的な説明は省略する。   4 to 6, the case where the first motor 3 is in the driving state and the second motor 4 is in the non-driving state has been described. When the first motor 3 is in the non-driving state and the second motor 4 is in the driving state, the operating states of the first cam clutch 50 and the second cam clutch 60 are the same as those shown in FIG. It is the opposite of the state. Since it is only necessary to reverse the first cam clutch 50 and the second cam clutch 60 shown in FIG. 6, detailed description will be omitted.

このように、第１実施形態の駆動力伝達装置１によれば、簡単な構造で安価に装置を形成することができ、効率良く回転数を切り替えることが可能となる。また、第１カムクラッチ５０と第２カムクラッチ６０を用いることで、簡単な構造で第１内輪５１と第１外輪５２との動力の伝達を適切に接続又は切離することが可能となる。さらに、１つの軸上に第１入力部５と第２入力部６が設置されることとなり、装置を小型化することが可能となる。また、スリーブ８を用いることによって、第１入力部５と第２入力部６の中心軸Ｃを適切にあわせることが可能となる。   As described above, according to the driving force transmission device 1 of the first embodiment, it is possible to form the device with a simple structure at a low cost, and it is possible to efficiently switch the rotation speed. Further, by using the first cam clutch 50 and the second cam clutch 60, it becomes possible to properly connect or disconnect the power transmission between the first inner ring 51 and the first outer ring 52 with a simple structure. Furthermore, since the first input unit 5 and the second input unit 6 are installed on one axis, the device can be downsized. Further, by using the sleeve 8, it becomes possible to properly align the central axes C of the first input section 5 and the second input section 6.

図８は、第１実施形態の駆動力伝達システム１０の組み付け方法を示す。図８（ａ）は、第１入力部５及び第２入力部６を組み付ける前の状態を示す。図８（ｂ）は、スリーブ８を組み付けた状態を示す。図８（ｃ）は、第１入力部５及び第２入力部６を組み付けた後の状態を示す。なお、図８では、第１カムクラッチ５０と第２カムクラッチ６０の内部構造は省略する。   FIG. 8 shows an assembling method of the driving force transmission system 10 of the first embodiment. FIG. 8A shows a state before the first input unit 5 and the second input unit 6 are assembled. FIG. 8B shows a state in which the sleeve 8 is assembled. FIG. 8C shows a state after the first input section 5 and the second input section 6 are assembled. Note that the internal structures of the first cam clutch 50 and the second cam clutch 60 are omitted in FIG.

In the support part 9, an input bearing 92 is installed in the case 91.

続いて、図８（ｂ）に示すように、スリーブ８を第１カムクラッチ５０又は第２カムクラッチ６０の内周に設置する。この時点で、スリーブ８は、第１カムクラッチ５０及び第２カムクラッチ６０の両方に接触するように設置しなくてもよい。   Subsequently, as shown in FIG. 8B, the sleeve 8 is installed on the inner circumference of the first cam clutch 50 or the second cam clutch 60. At this point, the sleeve 8 does not have to be installed so as to contact both the first cam clutch 50 and the second cam clutch 60.

次に、図８（ｃ）に示すように、第１入力部５の第１先端部５ｃと第１中間部５ｂ及び第２入力部６の第２先端部６ｃと第２中間部６ｂをそれぞれ入力用ベアリング９２に貫通させる。そして、第１入力部５の第１先端部５ｃと第１中間部５ｂの一部及び第２入力部６の第２先端部６ｃと第２中間部６ｂの一部をそれぞれ第１カムクラッチ５０及び第２カムクラッチ６０にそれぞれ挿入する。   Next, as shown in FIG. 8C, the first tip portion 5c and the first intermediate portion 5b of the first input portion 5 and the second tip portion 6c and the second intermediate portion 6b of the second input portion 6 are respectively removed. The bearing 92 for input is penetrated. Then, the first tip portion 5c and a part of the first intermediate portion 5b of the first input portion 5 and the second tip portion 6c and a portion of the second intermediate portion 6b of the second input portion 6 are respectively connected to the first cam clutch 50. And the second cam clutch 60, respectively.

最後に、第１入力部５の先端部５ａ及び第２入力部６の先端部６ａをそれぞれスリーブ８に挿入する。この時、第１入力部５の基端部５ａと中間部５ｂとの境界に形成された段部及び第２入力部６の基端部６ａと中間部６ｂとの境界に形成された段部が入力用ベアリング９２にそれぞれ接触すると、自然にスリーブ８が中央に位置するように、予め寸法を設定しておくと好ましい。   Finally, the tip 5 a of the first input section 5 and the tip 6 a of the second input section 6 are inserted into the sleeve 8. At this time, a step portion formed at a boundary between the base end portion 5a and the intermediate portion 5b of the first input portion 5 and a step portion formed at a boundary between the base end portion 6a and the intermediate portion 6b of the second input portion 6. It is preferable to preliminarily set the dimensions so that the sleeve 8 is naturally positioned at the center when each of the contacts contacts the input bearing 92.

このように、第１実施形態の駆動力伝達システム１０の組み付け方法によれば、第１入力部５と第２入力部６の中心軸Ｃを、容易且つ適切にあわせることが可能となる。したがって、生産性が向上し、低コストに製作することが可能となる。   As described above, according to the assembling method of the driving force transmission system 10 of the first embodiment, the central axes C of the first input section 5 and the second input section 6 can be easily and appropriately aligned. Therefore, it is possible to improve productivity and manufacture at low cost.

It is preferable that the first motor 3 and the second motor 4 are not driven simultaneously.

次に、駆動力伝達装置１の作動について説明する。ここでは、第１モータ３が駆動状態、第２モータ４が非駆動状態の場合について説明する。   Next, the operation of the driving force transmission device 1 will be described. Here, the case where the first motor 3 is in the driving state and the second motor 4 is in the non-driving state will be described.

図１０は、第２実施形態の駆動力伝達装置１の第１カム５４の作動状態を示す。   FIG. 10 shows an operating state of the first cam 54 of the driving force transmission device 1 according to the second embodiment.

第１モータ３が駆動すると、駆動力伝達装置１の第１入力部５が回転し、第１外輪５２が回転する。第１外輪５２が図１０に示した黒塗り矢印Ｅ１の方向に回転すると、第１カム５４は即座に回転し、第１外輪５２及び第１内輪５１と噛み合う。したがって、第１外輪５２、第１カム５４、第１内輪５１及び出力部７のクラッチ連結部７１は、一体に黒塗り矢印Ｅ２の方向に回転する。   When the first motor 3 is driven, the first input portion 5 of the driving force transmission device 1 rotates and the first outer ring 52 rotates. When the first outer ring 52 rotates in the direction of the black arrow E1 shown in FIG. 10, the first cam 54 immediately rotates and meshes with the first outer ring 52 and the first inner ring 51. Therefore, the first outer ring 52, the first cam 54, the first inner ring 51 and the clutch connecting part 71 of the output part 7 rotate integrally in the direction of the black arrow E2.

図１１は、第２実施形態の駆動力伝達装置１の第２カム６４の非作動状態を示す。   FIG. 11 shows a non-actuated state of the second cam 64 of the driving force transmission system 1 of the second embodiment.

図１０の状態で出力部７のクラッチ連結部７１が回転すると、図１１に示す白塗り矢印Ｅ３の方向に第２内輪６１が回転する。第２内輪６１が図１１に示した白塗り矢印Ｅ３の方向に回転すると、第２カム６４は即座に回転し、第２外輪６２から離間する。したがって、第２内輪６１が空転し、第２外輪６２は回転しない。   When the clutch connecting portion 71 of the output portion 7 rotates in the state of FIG. 10, the second inner ring 61 rotates in the direction of the white arrow E3 shown in FIG. When the second inner ring 61 rotates in the direction of the white arrow E3 shown in FIG. 11, the second cam 64 immediately rotates and separates from the second outer ring 62. Therefore, the second inner ring 61 spins and the second outer ring 62 does not rotate.

図１２は、第１モータ３が作動状態の時の第２実施形態の駆動力伝達装置１の動力伝達を示す。   FIG. 12 shows the power transmission of the driving force transmission device 1 of the second embodiment when the first motor 3 is in the operating state.

第１カム５４は、第１外輪５２から第１内輪５１への動力の伝達を接続する。その結果、図９に示した第１モータ３の駆動力が駆動力伝達装置１を介して図９に示した回転体２に伝達される。すなわち、図９に示した第１モータ３が回転すると、第１入力部５、第１外輪５２、第１カム５４、第１内輪５１、クラッチ連結部７１及び円板部７２が回転し、伝達部７３を移動させる。そして、伝達部７３の移動により、図９に示した回転体２が回転する。   The first cam 54 connects the transmission of power from the first outer ring 52 to the first inner ring 51. As a result, the driving force of the first motor 3 shown in FIG. 9 is transmitted to the rotating body 2 shown in FIG. 9 via the driving force transmission device 1. That is, when the first motor 3 shown in FIG. 9 rotates, the first input portion 5, the first outer ring 52, the first cam 54, the first inner ring 51, the clutch connecting portion 71, and the disc portion 72 rotate and transmit. The part 73 is moved. Then, due to the movement of the transmission portion 73, the rotating body 2 shown in FIG. 9 rotates.

しかしながら、第２カム６４は、第２内輪６１から第２外輪６２への動力の伝達を切断する。その結果、図９に示した第１モータ３の駆動力は駆動力伝達装置１を介して図９に示した第２モータ４へは伝達されない。すなわち、クラッチ連結部７１の回転により、第２内輪６１は回転するが、第２外輪６２及び第２入力部６が回転することはない。   However, the second cam 64 disconnects the power transmission from the second inner ring 61 to the second outer ring 62. As a result, the driving force of the first motor 3 shown in FIG. 9 is not transmitted to the second motor 4 shown in FIG. 9 via the driving force transmission device 1. That is, the second inner ring 61 is rotated by the rotation of the clutch connecting part 71, but the second outer ring 62 and the second input part 6 are not rotated.

図１３は、第２モータ４が作動状態の時の第２実施形態の駆動力伝達装置１の動力伝達を示す。   FIG. 13 shows the power transmission of the driving force transmission device 1 of the second embodiment when the second motor 4 is in the operating state.

図１０〜図１２では、第１モータ３が駆動状態、第２モータ４が非駆動状態の場合について説明した。第１モータ３が非駆動状態、第２モータ４が駆動状態の場合については、図１３に示すように、第１カムクラッチ５０と第２カムクラッチ６０の作動状態が、図１２に示した作動状態とは逆になる。図１２に示した第１カムクラッチ５０と第２カムクラッチ６０を反対にすればよいだけなので、具体的な説明は省略する。   10 to 12, the case where the first motor 3 is in the driving state and the second motor 4 is in the non-driving state has been described. When the first motor 3 is in the non-driving state and the second motor 4 is in the driving state, the operating states of the first cam clutch 50 and the second cam clutch 60 are the same as those shown in FIG. 12, as shown in FIG. It is the opposite of the state. Since it is only necessary to reverse the first cam clutch 50 and the second cam clutch 60 shown in FIG. 12, detailed description will be omitted.

このように、第２実施形態の駆動力伝達装置１によれば、簡単な構造で安価に装置を形成することができ、効率良く回転数を切り替えることが可能となる。また、第１カムクラッチ５０と第２カムクラッチ６０を用いることで、簡単な構造で第１内輪５１と第１外輪５２との動力の伝達を適切に接続又は切離することが可能となる。さらに、１つの軸上に第１入力部５、第２入力部６及び出力部７が設置されることとなり、装置を小型化することが可能となる。   As described above, according to the driving force transmission device 1 of the second embodiment, the device can be formed at a low cost with a simple structure, and the number of rotations can be efficiently switched. Further, by using the first cam clutch 50 and the second cam clutch 60, it becomes possible to properly connect or disconnect the power transmission between the first inner ring 51 and the first outer ring 52 with a simple structure. Further, the first input unit 5, the second input unit 6, and the output unit 7 are installed on one axis, and the device can be downsized.

図１４は、第３実施形態の駆動力伝達装置１及び駆動力伝達システム１０を示す。   FIG. 14 shows the driving force transmission device 1 and the driving force transmission system 10 of the third embodiment.

図１４に示す第３実施形態の駆動力伝達システム１０は、出力部７を第１出力部７ａと第２出力部７ｂに分けたものである。第１出力部７ａは、第１入力部５及び第１カムクラッチ５０を経て、第１モータ３の駆動力を出力する。第２出力部７ｂは、第２入力部６及び第２カムクラッチ６０を経て第２モータ４の駆動力を出力する。なお、第１モータ３と第２モータ４は、第１出力部７ａと第２出力部７ｂを紙面上で同じ方向に回転させるものとする。   In the driving force transmission system 10 of the third embodiment shown in FIG. 14, the output section 7 is divided into a first output section 7a and a second output section 7b. The first output unit 7 a outputs the driving force of the first motor 3 via the first input unit 5 and the first cam clutch 50. The second output section 7b outputs the driving force of the second motor 4 via the second input section 6 and the second cam clutch 60. In addition, the 1st motor 3 and the 2nd motor 4 shall rotate the 1st output part 7a and the 2nd output part 7b in the same direction on a paper surface.

第１カムクラッチ５０と第２カムクラッチ６０の構造は、第１実施形態及び第２実施形態と同様である。図４〜図６で説明した第１実施形態と同様に、第１モータ３が駆動状態、第２モータ４が非駆動状態の場合、第１モータ３が回転すると、第１入力部５、第１内輪５１、第１カム５４、第１外輪５２、クラッチ連結部７１及び円板部７２が回転し、伝達部７３を移動させる。そして、伝達部７３の移動により、図１に示した回転体２が回転する。   The structures of the first cam clutch 50 and the second cam clutch 60 are the same as those of the first and second embodiments. Similar to the first embodiment described with reference to FIGS. 4 to 6, when the first motor 3 is in the driving state and the second motor 4 is in the non-driving state, when the first motor 3 rotates, the first input unit 5, The first inner ring 51, the first cam 54, the first outer ring 52, the clutch connecting portion 71, and the disc portion 72 rotate to move the transmitting portion 73. Then, the rotating body 2 shown in FIG. 1 is rotated by the movement of the transmitting portion 73.

しかしながら、図４〜図６で説明した第１実施形態と同様に、伝達部７３の移動により、第２外輪６２が回転すると、第２カム６４は、第２外輪６２から第２内輪６１への動力の伝達を切断する。その結果、図１４に示した第１モータ３の駆動力は駆動力伝達装置１を介して第２モータ４へは伝達されない。すなわち、伝達部７３の移動により、第２外輪６２は回転するが、第２内輪６１及び第２入力部６が回転することはない。   However, similarly to the first embodiment described with reference to FIGS. 4 to 6, when the second outer ring 62 rotates due to the movement of the transmission portion 73, the second cam 64 moves the second outer ring 62 to the second inner ring 61. Disconnect power transmission. As a result, the driving force of the first motor 3 shown in FIG. 14 is not transmitted to the second motor 4 via the driving force transmission device 1. That is, the movement of the transmission portion 73 causes the second outer ring 62 to rotate, but the second inner ring 61 and the second input portion 6 do not rotate.

第１モータ３が非駆動状態、第２モータ４が駆動状態の場合については、第１カムクラッチ５０と第２カムクラッチ６０の作動状態が、逆になるだけなので、具体的な説明は省略する。   In the case where the first motor 3 is in the non-driving state and the second motor 4 is in the driving state, the operating states of the first cam clutch 50 and the second cam clutch 60 are only opposite to each other, and thus detailed description thereof will be omitted. .

なお、第３実施形態の駆動力伝達システム１０は、伝達部７３を第１伝達部７３ａと第２伝達部７３ｂに分けてもよい。すなわち、２本のチェーン又はベルト等を回転体２に並列に巻き掛けてもよい。そして、第１モータ３によって第１伝達部７３ａが駆動され、第２モータ４によって第２伝達部７３ｂが駆動されるように設置する。   In the driving force transmission system 10 of the third embodiment, the transmission part 73 may be divided into a first transmission part 73a and a second transmission part 73b. That is, two chains or belts may be wound around the rotating body 2 in parallel. The first motor 3 drives the first transmission portion 73a, and the second motor 4 drives the second transmission portion 73b.

このように、第３実施形態の駆動力伝達装置１によれば、単純な構造で、安価に装置を形成することが可能となる。   As described above, according to the driving force transmission device 1 of the third embodiment, it is possible to form the device inexpensively with a simple structure.

For example, when the rotating body 2 is housed in the support portion 9, as shown in FIG. 15, the constituent elements except the rotating body 2 and the transmission portion 73 are collectively arranged at predetermined corner portions.

このように、第４実施形態の駆動力伝達システム１０によれば、単純な構造で、安価に装置を形成することに加え、スペースを有効に利用することが可能となる。   As described above, according to the driving force transmission system 10 of the fourth embodiment, it is possible to form the device inexpensively with a simple structure and to effectively use the space.
