Description

この発明は、モータによって駆動される駆動軸方向と減速機の出力軸方向が直交する構造の直交型減速機に関するものである。   The present invention relates to an orthogonal speed reducer having a structure in which a drive shaft direction driven by a motor and an output shaft direction of the speed reducer are orthogonal to each other.

直交型減速機においては、出力軸が中空及び中実形状の機種があり、特に出力軸中実軸機種においては電動機から見て右側に出力軸が突出した機種と左側に突出した機種の２機種の製品仕様となっている。このような従来の直交型減速機として、電動機部分と減速機部分が一体に形成された構成の減速機部分の出力軸の出力方向が減速機ケースの左側、右側の何れの方向に配置しても最終段歯車が装着可能に形成され、出力の方向が、左側、右側の何れにも対応できるようにしたものがある（例えば特許文献１参照）。   In orthogonal reduction gears, there are models with hollow and solid output shafts. In particular, the output shaft solid shaft model has two models, one with the output shaft protruding to the right and the one with the left protruding from the motor. It has become the product specification. As such a conventional orthogonal speed reducer, the output direction of the output shaft of the speed reducer portion having a configuration in which the motor portion and the speed reducer portion are integrally formed is arranged on either the left side or the right side of the speed reducer case. In some cases, the final gear is formed so that it can be mounted, and the output direction can correspond to either the left side or the right side (see, for example, Patent Document 1).

特開２０００−２７０５１５号公報（第１頁、図１）JP 2000-270515 A (first page, FIG. 1)

上記のような従来の直交型減速機においては、出力軸が１種類のもので左右の何れの出力方向にも対応できるというものの、出力軸の突出方向を変更するときに、駆動歯車に係合する従動歯車と中間歯車を保持している歯車軸は左右方向の位置を変更しない構成としているため、最終段歯車を有する出力軸を左側に突出させる場合と、右側に突出させる場合とで、出力軸に対する最終段歯車の左右方向の位置を変更する必要があり、さらに最終段歯車とベアリングの相対位置を位置決めするためのスペーサが必要になるなどの課題があった。   In the conventional orthogonal speed reducer as described above, although the output shaft is of a single type and can respond to either the left or right output direction, it is engaged with the drive gear when changing the protruding direction of the output shaft. Since the gear shaft holding the driven gear and the intermediate gear does not change the position in the left-right direction, the output shaft having the final gear is projected to the left and the right is projected to the right. There is a problem in that it is necessary to change the position of the final gear in the left-right direction with respect to the shaft, and a spacer is required to position the relative position of the final gear and the bearing.

この発明は、上記のような従来技術の課題を解消するためになされたもので、出力軸に対する最終段歯車の左右方向の位置を変更したり、最終段歯車とベアリングの相対位置を位置決めするためのスペーサを用いる必要がない、部品点数が削減された直交型減速機を提供することを目的としている。   The present invention has been made to solve the above-described problems of the prior art, in order to change the position in the left-right direction of the final gear relative to the output shaft, or to position the relative position of the final gear and the bearing. It is an object of the present invention to provide an orthogonal speed reducer with a reduced number of parts that does not require the use of this spacer.

この発明による直交型減速機は、ギヤケースの中心部に位置するように設けられた第１歯車を有する駆動軸と、上記駆動軸の方向に対し軸方向が直交する方向に配設され、かつ上記ギヤケースに対して、上記駆動軸の方向から見て左右任意の向きに取り付け可能に支承され、上記第１歯車に係合する第２歯車及びこの第２歯車の一側部または他側部に同軸に設けられた第３歯車を有する第２第３歯車軸組立体と、この第２第３歯車軸組立体を支承して上記第１歯車から対称位置に配設され、かつ外径が左右とも同一寸法に形成した第２第３歯車軸組立体軸受と、上記第２第３歯車軸組立体に対し軸方向が平行で少なくとも一端部が上記ギヤケースから突出され、かつ上記ギヤケースに対して上記駆動軸の方向から見て左右任意の向きに取り付け可能に支承され、上記第３歯車に直接または他の減速歯車を介して係合する最終段歯車を有する出力軸と、この出力軸を支承して上記第１歯車から対称位置に配設され、かつ外径が左右とも同一寸法に形成した出力軸受とを備えるように構成されたものである。 An orthogonal speed reducer according to the present invention is provided with a drive shaft having a first gear provided so as to be positioned at the center of a gear case, and disposed in a direction orthogonal to the direction of the drive shaft, A second gear that is supported so as to be attached to the gear case in any direction left and right when viewed from the direction of the drive shaft, and that is coaxial with one side or the other side of the second gear. A second third gear shaft assembly having a third gear provided on the first gear, and a second gear shaft assembly that is supported by the second gear shaft assembly and disposed at a symmetric position from the first gear, and has outer diameters on both the left and right sides. The second and third gear shaft assembly bearings having the same dimensions and the axial direction parallel to the second and third gear shaft assembly, at least one end projecting from the gear case, and the drive with respect to the gear case Mounting in any direction left and right as viewed from the axis direction Capable is supported, an output shaft having a final stage gear which engages through the third direct or other reduction gear to gear, is arranged to support the output shaft from the first gear to the symmetrical position, And it is comprised so that an outer diameter may be provided with the output bearing formed in the same dimension on either side .

この発明においては、駆動軸に設けられた第１歯車に係合する第２歯車及びこの第２歯車の一側部または他側部に同軸に設けられた第３歯車を有する第２第３歯車軸組立体を支承して上記第１歯車から対称位置に配設され、かつ外径が左右とも同一寸法に形成した第２第３歯車軸組立体軸受と、出力軸を支承して上記第１歯車から対称位置に配設され、かつ外径が左右とも同一寸法に形成した出力軸受とを備えたことにより、出力軸突出方向の変更が組立時の仕様に応じて第２第３歯車軸組立体と出力軸の双方の左右を同時に入れ替えるだけで簡単に対応できる。このため、出力軸に対する最終段歯車の左右方向の位置を変更する必要がなく、位置決め用のスペーサを用いる必要もないので、部品点数が削減できる。 In the present invention, a second third gear having a second gear engaged with the first gear provided on the drive shaft and a third gear provided coaxially on one side or the other side of the second gear. A shaft assembly is supported and the second gear shaft assembly bearing, which is disposed symmetrically with respect to the first gear and has the same outer diameter on both the left and right sides, and the output shaft is supported on the first gear. By providing an output bearing that is arranged symmetrically from the gear and whose outer diameter is the same on both the left and right sides, the second and third gear shaft assemblies can be changed in the output shaft protruding direction according to the specifications at the time of assembly. It can be easily handled by simply swapping both the left and right sides of the solid and the output shaft. For this reason, it is not necessary to change the position in the left-right direction of the final gear relative to the output shaft, and it is not necessary to use a positioning spacer, so that the number of parts can be reduced.

A bearing 3 (3a, 3b) having the same structure and a bearing 4 (4a, 4b) having the same structure on the left and right for supporting the output shaft 23 with respect to the gear case 21 are provided.

上記ギヤケース２１は左右対称的に形成されており、上記駆動軸１１はギヤケース２１の図の左右方向の中心線Ａ上に位置するように設置されている。また、上記第２第３歯車軸組立体２２は、駆動軸１１の方向（軸方向）に対して直交する方向に配設され、駆動軸１１の方向ないしは電動機１側から見て左右任意の向きに取り付け可能に支承されている。そのために、第２第３歯車軸組立体２２を支承する軸受３ａ、３ｂ及びその支持部３０ａ、３０ｂは中心線Ａに対して左右対称位置に同一径で設けられている。また、上記出力軸２３を支承する軸受４ａ、４ｂ及びその支持部４０ａ、４０ｂも中心線Ａに対して左右対称位置に同一径で設けられており、組立時に第２第３歯車軸組立体２２と出力軸２３の左右方向を同時に入れ替えることで図２（ａ）に示す、出力軸２３が右側に突出されたもの、及び図２（ｂ）に示す出力軸２３が左側に突出されたものを選択できるように構成されている。なお、その他の構成は従来技術と同様であるので説明を省略する。
The gear case 21 is symmetrically formed, and the drive shaft 11 is installed on the center line A in the left-right direction of the gear case 21 in the drawing. The second and third gear shaft assemblies 22 are disposed in a direction orthogonal to the direction of the drive shaft 11 (axial direction), and the direction of the drive shaft 11 or an arbitrary left and right direction when viewed from the motor 1 side. It is supported so that it can be attached to. For this purpose, the bearings 3a and 3b for supporting the second and third gear shaft assemblies 22 and the support portions 30a and 30b are provided with the same diameter at symmetrical positions with respect to the center line A. The bearings 4a, 4b for supporting the output shaft 23 and the support portions 40a, 40b are also provided at the same symmetrical position with respect to the center line A with the same diameter, and the second third gear shaft assembly 22 is assembled at the time of assembly. shown in FIG. 2 (a) by exchanging the left and right direction of the output shaft 23 at the same time, that the output shaft 23 is protruded to the right, and those output shaft 23 shown in FIG. 2 (b) is protruded to the left It is configured to be selectable. Since other configurations are the same as those of the prior art, description thereof is omitted.

次に、上記のように構成された実施の形態１の動作について説明する。先ず、直交型減速機２を組み立てる際には、同一軸上に配置された第２歯車第３歯車軸組立体２２を支持する例えば互いに同一型番からなる軸受３ａ、軸受３ｂをギヤケース２の中心に対し対称位置となるように所定位置に装着する。同様に出力軸２３についてもギヤケース２の中心に対し対称位置となるよう例えば互いに同一型番からなる軸受け４ａ、４ｂを所定位置に装着する。そして、図２（ａ）の場合、第３歯車Ｇ３、最終段歯車Ｇ９が中心線Ａの右側となるように、また、図２（ｂ）の場合、第３歯車Ｇ３、最終段歯車Ｇ９が左側となるように、ギヤケース２１の所定位置に順次装着、固定する。さらに、ギヤケース２１の中心に第１歯車Ｇ１を有する電動機１の回転軸兼駆動軸１１を配置し、第１歯車Ｇ１を第２歯車Ｇ２に噛合させる。なお、オイル（図示省略）、オイルシール、封止カバーの取り付けなどは従来装置と同様である。   Next, the operation of the first embodiment configured as described above will be described. First, when assembling the orthogonal reduction gear 2, the bearing 3 a and the bearing 3 b having the same model number, for example, supporting the second gear and the third gear shaft assembly 22 arranged on the same shaft are centered on the gear case 2. It is mounted at a predetermined position so as to be symmetrical. Similarly, for example, bearings 4a and 4b having the same model number are mounted at predetermined positions so that the output shaft 23 is positioned symmetrically with respect to the center of the gear case 2. In the case of FIG. 2A, the third gear G3 and the final gear G9 are on the right side of the center line A, and in the case of FIG. 2B, the third gear G3 and the final gear G9 are The gear case 21 is sequentially mounted and fixed so as to be on the left side. Furthermore, the rotation shaft / drive shaft 11 of the electric motor 1 having the first gear G1 is arranged at the center of the gear case 21, and the first gear G1 is engaged with the second gear G2. Note that oil (not shown), oil seal, sealing cover and the like are the same as those of the conventional apparatus.

上記のように、実施の形態１によれば、第１歯車Ｇ１を有する駆動軸１１をギヤケース２１の中心線Ａ上に配置する一方、第１歯車Ｇ１に係合する第２歯車Ｇ２及び第３歯車Ｇ３を有する第２歯車第３歯車軸組立体２２と、第３歯車Ｇ３に係合する最終段歯車Ｇ９を有する出力軸２３を、ギヤケース２１の中心線Ａに対し駆動軸１１の軸方向から見て左右任意の向きに取り付け可能にしたので、組立時に仕様に応じて第２第３歯車軸組立体２２と出力軸２３の双方の左右を同時に入れ替えるだけで、１通りの部品揃えにより、出力軸２３の突出部が左右何れの方向でも簡単に対応することができる。また、出力軸２３に対する最終段歯車Ｇ９の左右方向の位置を変更する手段とその変更操作の必要がなく、位置決め用のスペーサを用いる必要もない。そのため、部品点数や加工数が削減できるという効果が得られ、生産設備や生産工程の環境負荷も低減できる。   As described above, according to the first embodiment, the drive shaft 11 having the first gear G1 is disposed on the center line A of the gear case 21, while the second gear G2 and the third gear G1 that are engaged with the first gear G1. A second gear, a third gear shaft assembly 22 having a gear G3, and an output shaft 23 having a final stage gear G9 engaged with the third gear G3 are connected to the center line A of the gear case 21 from the axial direction of the drive shaft 11. Since it can be mounted in any direction left and right as seen, it is possible to output by simply aligning the left and right of both the second and third gear shaft assembly 22 and the output shaft 23 according to the specifications at the time of assembly. The protruding portion of the shaft 23 can easily cope with either the left or right direction. In addition, there is no need for means for changing the position of the last gear G9 in the left-right direction with respect to the output shaft 23 and the changing operation thereof, and there is no need to use a positioning spacer. Therefore, the effect that the number of parts and the number of processes can be reduced is obtained, and the environmental load of the production facility and production process can be reduced.

実施の形態２．
図３は、この発明の実施の形態２に係る直交型減速機の要部を示す断面図である。なお、この実施の形態２の直交型減速機２Ａは、出力軸２３Ａが電動機１側から見て左右両方向に突出されたものであり、図の右側の突出部２３ｂの方が左側の突出部２３ａよりも直径が太く、かつ突出長が長く形成されている。その他の構成は上記実施の形態１と同様であるので説明を省略する。 Embodiment 2. FIG.
FIG. 3 is a cross-sectional view showing a main part of an orthogonal reduction gear according to Embodiment 2 of the present invention. In the orthogonal reduction gear 2A of the second embodiment, the output shaft 23A protrudes in both the left and right directions when viewed from the electric motor 1 side, and the right protrusion 23b in the drawing is the left protrusion 23a. The diameter is thicker than that, and the protruding length is longer. Since other configurations are the same as those of the first embodiment, description thereof is omitted.

上記のように構成された実施の形態２においては、直径が太く、かつ突出長が長い突出部２３ｂを電動機１側から見て左側に配置したものとしたい場合には、実施の形態１と全く同様に、組立時に第２第３歯車軸組立体２２と出力軸２３Ａの双方の左右を同時に入れ替えるだけで対応できる。従って、実施の形態１と同様に、組立時に仕様に応じて第２第３歯車軸組立体２２と出力軸２３Ａの双方の左右を同時に入れ替えるだけで簡単に対応できる。このため、出力軸２３Ａに対する最終段歯車Ｇ９の左右方向の位置を変更する必要がなく、位置決め用のスペーサを用いる必要もないので、部品点数が削減できるなど、実施の形態１と同様の効果が得られる。   In the second embodiment configured as described above, the projection 23b having a large diameter and a long projection length is arranged on the left side when viewed from the electric motor 1 side. Similarly, it is possible to cope with this by simply exchanging the left and right of both the second and third gear shaft assembly 22 and the output shaft 23A at the time of assembly. Therefore, as in the first embodiment, it is possible to easily cope with this by simply switching both the left and right sides of the second and third gear shaft assembly 22 and the output shaft 23A at the time of assembly according to the specifications. For this reason, there is no need to change the position in the left-right direction of the final gear G9 with respect to the output shaft 23A, and there is no need to use a positioning spacer. can get.

なお、上記実施の形態１、２では、２段減速方式の場合について説明したが、必ずしもそれに限定されるものではなく、例えば第２第３歯車軸組立体２２と出力軸２３、２３Ａの間に第４第５歯車軸組立体（図示省略）が介装された３段減速方式の場合などでも同様に構成できる。なお、３段減速方式において出力軸２３を右側に突出させる場合には、例えば、第２第３歯車軸組立体２２を図２（ｂ）のように第３歯車Ｇ３が中心線Ａの左に位置するように配置し、第４第５歯車軸組立体は、第４歯車が左側、第５歯車が右側に位置するように配置することで、出力軸２３を図２（ａ）と同一のものを流用するようにすることができる。なお、その場合において、出力軸２３の突出方向を左側に変更するときは、第２第３歯車軸組立体２２、第４第５歯車軸組立体（図示省略）、及び出力軸２３の三者の左右方向を同時に入れ替えることとなる。   In the first and second embodiments, the case of the two-stage reduction method has been described. However, the present invention is not necessarily limited to this, and for example, between the second and third gear shaft assembly 22 and the output shafts 23 and 23A. The same configuration can be made in the case of a three-stage reduction system in which a fourth and fifth gear shaft assembly (not shown) is interposed. When the output shaft 23 protrudes to the right side in the three-stage reduction method, for example, the second gear 3 shaft assembly 22 is moved to the left of the center line A as shown in FIG. The fourth and fifth gear shaft assemblies are arranged so that the fourth gear is located on the left side and the fifth gear is located on the right side, so that the output shaft 23 is the same as in FIG. Things can be diverted. In this case, when the projecting direction of the output shaft 23 is changed to the left side, the third of the second and third gear shaft assemblies 22, the fourth and fifth gear shaft assemblies (not shown), and the output shaft 23 are used. The left and right directions are simultaneously replaced.

また、上記実施の形態の説明では、左右に配置された軸受３ａ、３ｂ、及び軸受４ａ、４ｂを、それぞれ互いに同一のものによって構成した場合について例示したが、これに限定されるものではなく、軸受の外径とギヤケース２１の中心線Ａから軸受の外側端面までの距離が同一であればよく、軸受３ａと軸受３ｂ、または軸受４ａと軸受４ｂの内径は左右で異なっていても差し支えない。   In the description of the above embodiment, the bearings 3a and 3b and the bearings 4a and 4b arranged on the left and right are exemplified by the same ones. However, the present invention is not limited to this. The outer diameter of the bearing and the distance from the center line A of the gear case 21 to the outer end face of the bearing need only be the same, and the inner diameters of the bearing 3a and the bearing 3b or the bearing 4a and the bearing 4b may be different on the left and right.
