Description

本発明は、モータから入力される動力を減速させて伝達する減速機に関するものである。   The present invention relates to a decelerator that decelerates and transmits power input from a motor.

従来の減速機として例えば、特許文献１に記載されているものが使用されている。この文献に示す減速機は、駆動モータの駆動軸に設けられるウォームに対して回転方向を変化させるウォームホイールを噛合し、そのウォームホイールに対して噛合する複数の歯車をそれぞれ上部減速機構収容部と下部減速機構収容部に交互に並設配置したため、駆動軸と直交する出力軸を有した減速機のコンパクト化を図ることができるとしている。

しかしながら、外部機器との接続の関係から、駆動軸に同じ方向と、駆動軸に垂直な方向の２方向に出力を行うことを必要とされる場合がある。このような場合、上記した特許文献１に示すような駆動軸に垂直な方向に出力を行う減速機を取付けた駆動モータと、駆動軸に同じ方向に出力を行う減速機を取付けた駆動モータの２つを使用する必要があり、取付けスペースやコストの増大に繋がるという問題があった。   However, there are cases where it is necessary to output in two directions, the same direction as the drive shaft and the direction perpendicular to the drive shaft, due to the connection with the external device. In such a case, a drive motor having a speed reducer that outputs in the direction perpendicular to the drive shaft as shown in Patent Document 1 and a drive motor having a speed reducer that outputs in the same direction on the drive shaft. There is a problem that it is necessary to use two, which leads to an increase in installation space and cost.

本発明は、以上の点に鑑み、一つの駆動モータの入力から互いに異なる２方向への出力を行うことができる減速機を提供することを目的とする。   In view of the above, an object of the present invention is to provide a speed reducer that can perform output in two different directions from the input of one drive motor.

上記した目的を達成するために、本発明の請求項１は、駆動モータの駆動軸の回転を減速させて伝達する減速機において、減速機は駆動モータの駆動軸の回転を複数の歯車の伝達により駆動軸と同方向に減速させて伝達する平行軸減速部と、平行軸減速部から伝達された回転を受けて方向を変換させて伝達する食違い軸減速部とを有し、食違い軸減速部は平行軸減速部のいずれかの歯車と同軸で回転する第１食違い軸歯車と、第１食違い軸歯車と噛み合って第１食違い軸歯車と垂直な方向に回転する第２食違い軸歯車とにより回転の方向を変換させて伝達し、平行軸減速部のいずれかの歯車と同軸で駆動モータの駆動軸と同方向に回転する第１出力軸と、第２食違い軸歯車の回転を受けて第２食違い軸歯車と同方向に回転する第２出力軸とを備えた構成とした。   In order to achieve the above-described object, claim 1 of the present invention is a reduction gear that transmits the rotation of the drive shaft of the drive motor by decelerating the rotation of the drive shaft of the drive motor. A parallel shaft speed reducer that decelerates and transmits in the same direction as the drive shaft, and a staggered shaft speed reducer that receives the rotation transmitted from the parallel shaft speed reducer to change the direction and transmits the staggered shaft. The speed reducer is a first staggered shaft gear that rotates coaxially with one of the gears of the parallel shaft speed reducer, and a second staggered gear that meshes with the first staggered shaft gear and rotates in a direction perpendicular to the first staggered shaft gear. A first output shaft that transmits the rotation direction of the shaft by changing the direction of rotation with a differential shaft gear, and that rotates in the same direction as the drive shaft of the drive motor coaxially with one of the gears of the parallel shaft reduction unit; And a second output shaft that rotates in the same direction as the second staggered shaft gear. And the example was constructed.

上記した構成によれば、一つの駆動モータの入力から、駆動モータの駆動軸と平行な第１出力軸と、駆動軸と垂直な第２出力軸との２方向への出力が可能である。   According to the configuration described above, it is possible to output in two directions from the input of one drive motor, the first output shaft parallel to the drive shaft of the drive motor and the second output shaft perpendicular to the drive shaft.

以下、本発明の実施の形態の例を図面に基づいて説明する。図１〜図３は本発明の実施例にかかる減速機１の外観を示した図であり、図１は正面図、図２は平面図を示し、図３は背面図を示す。図４〜図６は減速機１の内部構造を示した図であり、図４は正面図、図５は平行軸減速部５の構造を左側面から示す図、図６は食違い軸減速部６の構造を右側面から示す図である。   Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. 1 to 3 are views showing an appearance of a reduction gear 1 according to an embodiment of the present invention. FIG. 1 is a front view, FIG. 2 is a plan view, and FIG. 3 is a rear view. 4 to 6 are diagrams showing the internal structure of the speed reducer 1. FIG. 4 is a front view, FIG. 5 is a diagram showing the structure of the parallel shaft speed reducing unit 5 from the left side, and FIG. It is a figure which shows the structure of 6 from the right side.

まず、図１〜図３を用いて減速機１の外観について説明する。減速機１のケーシングが本体部２と、側面カバー３と、正面カバー４とで略直方体形状に構成され、駆動モータ５０がケーシング外部で側面カバー３にネジ止めで固定されて取付けられている。減速機１のケーシングは側面カバー３と反対側を、正面側、背面側ともに段状に削ぎ落とされた段部８，９を備えた形状となっており、さらに背面側の段部９は出力歯車４０（後述）が収まるように形成されている。これにより出力歯車４０がケーシング背面側に突出することがない。   First, the external appearance of the reduction gear 1 will be described with reference to FIGS. The casing of the speed reducer 1 is formed in a substantially rectangular parallelepiped shape with the main body 2, the side cover 3, and the front cover 4, and the drive motor 50 is fixed to the side cover 3 with screws and attached outside the casing. The casing of the speed reducer 1 has a shape including stepped portions 8 and 9 that are scraped off on the opposite side to the side cover 3 on both the front side and the back side. A gear 40 (described later) is formed to be accommodated. As a result, the output gear 40 does not protrude to the casing back side.

次に、図４〜図６を用いて減速機１の内部構造について説明する。ケーシングの本体部２の内部左側には駆動モータ５０からの回転を入力方向と同方向に減速させる平行軸減速部５を収容する第１収容部５Ａを備え、左側には回転方向を変換させて減速させる食違い軸減速部６を収容する第２収容部６Ａを備えており、それぞれが仕切り壁７で仕切られている。   Next, the internal structure of the speed reducer 1 will be described with reference to FIGS. On the left side of the casing body 2 is provided with a first housing part 5A for housing a parallel shaft speed reducing part 5 that decelerates rotation from the drive motor 50 in the same direction as the input direction. A second accommodating portion 6 </ b> A that accommodates the staggered shaft decelerating portion 6 to be decelerated is provided, and each is partitioned by a partition wall 7.

第１収容部５Ａに収容されている平行軸減速部５は、モータピニオン５４、第１歯車１２、第２歯車２０を備えている。側面カバー３に取付けられた駆動モータ５０の駆動軸５２が側面カバー３と垂直な方向に挿通孔３ａからケーシングの第１収容部５Ａ内に挿入され、駆動軸５２に支持されたモータピニオン５４から、順次に第１歯車１２、第２歯車２０が連結し、第１歯車１２は大歯車１２ａと小歯車１２ｂを備えている。詳述すると、モータピニオン５４が第１歯車１２の大歯車１２ａと噛み合い、第１歯車１２の小歯車１２ｂは第２歯車２０と噛み合い順次に減速する。   The parallel shaft reduction part 5 accommodated in the first accommodation part 5 </ b> A includes a motor pinion 54, a first gear 12, and a second gear 20. The drive shaft 52 of the drive motor 50 attached to the side cover 3 is inserted into the first housing portion 5A of the casing through the insertion hole 3a in the direction perpendicular to the side cover 3, and from the motor pinion 54 supported by the drive shaft 52. The first gear 12 and the second gear 20 are sequentially connected, and the first gear 12 includes a large gear 12a and a small gear 12b. More specifically, the motor pinion 54 meshes with the large gear 12a of the first gear 12, and the small gear 12b of the first gear 12 meshes with the second gear 20 and decelerates sequentially.

第１歯車１２は第１収容部５Ａ内に配設された第１中間軸１４に支持されており、この第１中間軸１４は軸受１６，１８を介して回転自在に支持されている。また、第２歯車２０は第１収容部５Ａと第２収容部６Ａとに渡って配設された第２中間軸２２に支持されている。この第２中間軸２２は一端側に挿入凹部２２ａを備え、この挿入凹部２２ａに第１出力軸２４が挿入され、１本のピン２７をそれぞれの貫通孔に貫通して一体に固定されている。第２中間軸２２の第１出力軸２４と反対側の端部が軸受２８に、第１出力軸２４が軸受２６に支持されているので、第２中間軸２２と第１出力軸２４が一体となって回転自在となっている。また、駆動軸５２及び第２中間軸２２は、図５に示すように奥行き方向ほぼ中央位置に配置されており、モータピニオン５４、第１歯車１２、第２歯車２０の歯車列は屈曲状に配列されている。なお、軸受２６に支持されている第１出力軸２４は駆動モータ５０が取付けられた側と同じ方向にケーシングから突出している。   The first gear 12 is supported by a first intermediate shaft 14 disposed in the first housing portion 5 </ b> A, and the first intermediate shaft 14 is rotatably supported via bearings 16 and 18. The second gear 20 is supported by a second intermediate shaft 22 that is disposed across the first housing portion 5A and the second housing portion 6A. The second intermediate shaft 22 has an insertion recess 22a on one end side. The first output shaft 24 is inserted into the insertion recess 22a, and a single pin 27 is passed through each through hole and fixed integrally. . Since the end of the second intermediate shaft 22 opposite to the first output shaft 24 is supported by the bearing 28 and the first output shaft 24 is supported by the bearing 26, the second intermediate shaft 22 and the first output shaft 24 are integrated. And is free to rotate. Further, as shown in FIG. 5, the drive shaft 52 and the second intermediate shaft 22 are disposed at substantially the center position in the depth direction, and the gear train of the motor pinion 54, the first gear 12, and the second gear 20 is bent. It is arranged. The first output shaft 24 supported by the bearing 26 protrudes from the casing in the same direction as the side on which the drive motor 50 is attached.

第２収容部６Ａに収容されている食違い軸減速部６は、第２中間軸２２の第１出力軸２４を取り付けた側の反対側に備えた第１ねじ歯車３０と、この第１ねじ歯車３０と噛み合う第２ねじ歯車３２とで構成されている。   The staggered shaft speed reduction part 6 accommodated in the second accommodation part 6A includes a first screw gear 30 provided on the opposite side of the second intermediate shaft 22 to the side on which the first output shaft 24 is attached, and the first screw The second screw gear 32 meshes with the gear 30.

第２ねじ歯車３２は第２出力軸３４に支持されており、この第２出力軸３４は軸受３６，３８を介して回転自在に支持されている。なお、第２出力軸３４はケーシング本体部２背面側にケーシングから突出しており、ケーシング外部に出力歯車４０を備えている。   The second screw gear 32 is supported by a second output shaft 34, and the second output shaft 34 is rotatably supported via bearings 36 and 38. The second output shaft 34 protrudes from the casing on the back side of the casing body 2 and includes an output gear 40 outside the casing.

駆動モータ５０による駆動軸５２の回転は、モータピニオン５４から第１歯車１２の大歯車１２ａに伝達され第１中間軸１４が回転する。第１中間軸１４の回転により第１歯車１２の小歯車１２ｂが回転し、第１歯車１２の小歯車１２ｂと噛み合う第２歯車２０を回転させる。第２歯車２０の回転により第２中間軸２２が回転し、第２中間軸２２の回転により同軸の第１出力軸２４及び第１ねじ歯車３０を回転させる。第１ねじ歯車３０は第２ねじ歯車３２と噛み合い、回転が垂直な方向に変換されて第２ねじ歯車３２が回転することにより第２出力軸３４が回転する。このようにして駆動軸５２の回転は駆動軸５２と平行な方向に減速されて伝達され、第１出力軸２４の回転として出力することができるともに、駆動軸５２と垂直に方向を変換された第２出力軸３４の回転としても出力することができる。   The rotation of the drive shaft 52 by the drive motor 50 is transmitted from the motor pinion 54 to the large gear 12a of the first gear 12, and the first intermediate shaft 14 rotates. The small gear 12b of the first gear 12 is rotated by the rotation of the first intermediate shaft 14, and the second gear 20 that meshes with the small gear 12b of the first gear 12 is rotated. The second intermediate shaft 22 is rotated by the rotation of the second gear 20, and the coaxial first output shaft 24 and the first screw gear 30 are rotated by the rotation of the second intermediate shaft 22. The first screw gear 30 meshes with the second screw gear 32, and the rotation is converted into a vertical direction, and the second screw gear 32 rotates, whereby the second output shaft 34 rotates. Thus, the rotation of the drive shaft 52 is decelerated and transmitted in a direction parallel to the drive shaft 52, and can be output as the rotation of the first output shaft 24, and the direction is changed perpendicularly to the drive shaft 52. It can also be output as rotation of the second output shaft 34.

また、図４に示すように、円筒状の第１ねじ歯車３０をケーシング左右方向に渡って配置し、第１ねじ歯車３０と噛み合う円盤状の第２ねじ歯車３２を第１ねじ歯車３０の直下に配置しているので、食違い軸減速部６の厚みを小さくすることができ、減速機１の外観形状を前述したように直方体形状から食違い軸減速部６側を正面側、背面側ともに削ぎ落として薄くし、段部８，９を形成することを可能としている。   Further, as shown in FIG. 4, a cylindrical first screw gear 30 is arranged in the left-right direction of the casing, and a disk-like second screw gear 32 that meshes with the first screw gear 30 is directly below the first screw gear 30. Therefore, the thickness of the staggered shaft speed reducing portion 6 can be reduced, and the outer shape of the speed reducer 1 is changed from the rectangular parallelepiped shape to the staggered shaft speed reducing portion 6 side from the front side and the rear side as described above. The stepped portions 8 and 9 can be formed by scraping and thinning.

第１出力軸２４は平行軸減速部５の最終段歯車である第２歯車２０と同軸に備えられているので、十分に減速されて出力される。また、第２出力軸３４も平行軸減速部５で減速された回転を受けた食違い軸減速部６の第２ねじ歯車３２と同軸に備えられているので、十分に減速された回転を出力することができる。ただし、これは本発明の権利範囲を限定するものではなく、第１出力軸２４は第２歯車２０と同軸であることに限らず、平行軸減速部５のいずれかの歯車と同軸であればよく、平行軸減速部５の歯車の数も限定しない。第１ねじ歯車３０についても平行軸減速部５のいずれかの歯車と同軸であればよく、第１出力軸２４とも必ずしも同軸である必要はない。また、第２出力軸３４が第２ねじ歯車３２と同軸に備えられた構成を示したが、第２ねじ歯車と噛み合わせて第２ねじ歯車の回転を同方向に伝達する他の歯車をさらに備えて、この歯車と同軸に備えられた構成としてもよい。   Since the first output shaft 24 is provided coaxially with the second gear 20 that is the final gear of the parallel shaft speed reducing unit 5, the first output shaft 24 is sufficiently decelerated and output. Further, since the second output shaft 34 is also provided coaxially with the second screw gear 32 of the staggered shaft speed reduction unit 6 that has received the speed reduced by the parallel axis speed reduction unit 5, a sufficiently decelerated rotation is output. can do. However, this does not limit the scope of the right of the present invention, and the first output shaft 24 is not limited to being coaxial with the second gear 20 but may be coaxial with any gear of the parallel shaft speed reducing unit 5. Well, the number of gears of the parallel shaft reduction part 5 is not limited. The first screw gear 30 may also be coaxial with any one of the gears of the parallel shaft speed reduction unit 5, and need not necessarily be coaxial with the first output shaft 24. In addition, the configuration in which the second output shaft 34 is provided coaxially with the second screw gear 32 is shown, but another gear that meshes with the second screw gear and transmits the rotation of the second screw gear in the same direction is further provided. It is good also as a structure provided with this gear and the same axis | shaft.

なお、本実施の形態の第１ねじ歯車３０が発明の第１食違い軸歯車を、第２ねじ歯車３２が発明の第２食違い軸歯車を構成している。しかし、本発明はこれに限定されず第１食違い軸歯車をウォームギヤとし、第２食違い軸歯車をウォームホイールとする構成でもよい。   The first screw gear 30 of the present embodiment constitutes the first staggered shaft gear of the invention, and the second screw gear 32 constitutes the second staggered shaft gear of the invention. However, the present invention is not limited to this, and the first staggered shaft gear may be a worm gear and the second staggered shaft gear may be a worm wheel.

図７は、本発明の減速機１の使用例を示した図であり、（ａ）は正面側からの斜視図、（ｂ）は背面側からの斜視図である。ここで示すものは、手前側と奥側に２つの外部歯車６０、７０が隙間を空けて並んで配置し、その左側にそれぞれ駆動モータ５０を接続した２つの減速機１を上下に並べて配置したものである。   FIG. 7 is a view showing an example of use of the speed reducer 1 of the present invention, where (a) is a perspective view from the front side, and (b) is a perspective view from the back side. In this example, two external gears 60 and 70 are arranged side by side with a gap between them on the front side and the back side, and two speed reducers 1 each having a drive motor 50 connected to the left side are arranged side by side. Is.

上側に配置された減速機１の出力歯車４０は、手前側に配置された外部歯車６０と噛み合い、上側の減速機１に接続された駆動モータ５０の駆動により出力歯車４０が回転して外部歯車６０を回転させる。下側に配置された減速機１の出力歯車４０は、奥側に配置された外部歯車７０と噛み合い、下側の減速機に接続された駆動モータ５０の駆動により出力歯車４０が回転して外部歯車７０を回転させる。   The output gear 40 of the speed reducer 1 arranged on the upper side meshes with the external gear 60 arranged on the near side, and the output gear 40 is rotated by the drive of the drive motor 50 connected to the upper speed reducer 1 so that the external gear is rotated. Rotate 60. The output gear 40 of the speed reducer 1 arranged on the lower side meshes with the external gear 70 arranged on the back side, and the output gear 40 rotates by driving of the drive motor 50 connected to the lower speed reducer. The gear 70 is rotated.

上下２つの減速機１は互いに反転させて配置させるだけでよく、減速機１の段部８，９により、外部歯車６０，７０との干渉を避けることができる。また、２つの外部歯車６０，７０の前後方向から減速機１や駆動モータ５０が飛び出すことがないので、機器の省スペース化を実現できる。   The upper and lower two reduction gears 1 need only be reversed and arranged, and the steps 8 and 9 of the reduction gear 1 can avoid interference with the external gears 60 and 70. Moreover, since the reduction gear 1 and the drive motor 50 do not jump out from the front-rear direction of the two external gears 60 and 70, it is possible to realize a space-saving device.

以上説明したように、本発明の構成によれば、一つの駆動モータ５０の駆動により駆動モータ５０の駆動軸５２と平行な第１出力軸２４と、駆動軸５２と垂直な第２出力軸３４との２方向への出力が可能である。また、食違い軸減速部６は第１ねじ歯車３０と第２ねじ歯車３２とで構成しているので、食違い軸減速部６を薄く形成することが可能であり、減速機１をコンパクトに形成し、機器の省スペース化を実現できる。   As described above, according to the configuration of the present invention, the first output shaft 24 parallel to the drive shaft 52 of the drive motor 50 and the second output shaft 34 perpendicular to the drive shaft 52 are driven by one drive motor 50. Can be output in two directions. Further, since the staggered shaft speed reduction unit 6 is composed of the first screw gear 30 and the second screw gear 32, the staggered shaft speed reduction unit 6 can be formed thin, and the speed reducer 1 can be made compact. Forming a space-saving device.
