主軸１０の下端部に設けたオイルポンプ１２は、図２の詳細に示す様に、ベアリング１１の取り付け用の板部材１１aに固定したボス１１cと、このボス１１c挿入して固定してありベアリング１１が設けられるボス１１aとの双方に取り付けたケース２２と、このケース２２内にケース２２の内側に接近させたネジ部２３を有し、主軸１０の下端に固定した回転体２４とで構成するネジポンプである。そして、このオイルポンプ１２は、前記ケース２２の上部に設けた孔２５は、オイルバス５に連通する潤滑油供給口である。   As shown in detail in FIG. 2, the oil pump 12 provided at the lower end of the main shaft 10 has a boss 11c fixed to a plate member 11a for mounting the bearing 11 and the boss 11c inserted and fixed. A screw pump comprising a case 22 attached to both of the bosses 11a provided with a screw body 23 and a rotating body 24 fixed to the lower end of the main shaft 10 having a screw portion 23 approaching the inside of the case 22 in the case 22 It is. In the oil pump 12, a hole 25 provided in the upper part of the case 22 is a lubricating oil supply port communicating with the oil bath 5.

そして前記オイルポンプ１２は、大径の傘歯車３０が主軸１０を矢印A方向に回転させられると主軸１０と共に回転体２４が回転し、そのネジ部２３のネジ溝によって、オイルバス５の潤滑油が孔２５を介してケース２２の内面に沿って下方室２６に送られパイプ１９を介して油室２０aに供給される。尚、前記オイルポンプ１２は、ネジポンプの実施例を記載したが、この他の形式例えばトロコイドポンプ等、主軸１０の端部に設置が可能であれば、他の形式のポンプでも良い。   When the large-diameter bevel gear 30 rotates the main shaft 10 in the direction of arrow A, the oil pump 12 rotates the rotating body 24 together with the main shaft 10. Is sent to the lower chamber 26 along the inner surface of the case 22 through the hole 25 and supplied to the oil chamber 20 a through the pipe 19. Although the oil pump 12 has been described as an example of a screw pump, other types such as a trochoid pump may be used as long as it can be installed at the end of the main shaft 10.

ケーシング２の上部ケーシング２aには、各種の機材が設置される底板２cを備えている。この底板２cの上面には、ベアリング４によって出力フランジ３を回転自在に支持すると共に、その中央部に前記主軸１０に設けた太陽歯車１７が遊星歯車４０を介して噛合う内歯歯車４１が固定してある。また、底板２cの下面には、主軸１０に沿って下方に向かって延出する軸受保持体１３が設けてある。この軸受保持体１３には、前記出力フランジ３に固定してあり、内歯歯車４１に噛合う遊星歯車４０を保持する遊星枠４３の下端を回転自在に保持するベアリング４２と、主軸１０の上部を回転自在に保持するベアリング１４とを備えている。   The upper casing 2a of the casing 2 is provided with a bottom plate 2c on which various equipments are installed. On the upper surface of the bottom plate 2c, an output gear 3 is rotatably supported by a bearing 4, and an internal gear 41 is fixed to which the sun gear 17 provided on the main shaft 10 is meshed via a planetary gear 40 at the center. It is. A bearing holder 13 that extends downward along the main shaft 10 is provided on the bottom surface of the bottom plate 2c. The bearing holder 13 is fixed to the output flange 3, and a bearing 42 that rotatably holds a lower end of a planetary frame 43 that holds a planetary gear 40 that meshes with an internal gear 41, and an upper portion of the main shaft 10. And a bearing 14 that holds the shaft rotatably.

太陽歯車１７と遊星歯車４０及び遊星枠４３は、遊星減速機構を構成するもので、前記太陽歯車１７が回転すると、この回転で遊星歯車４０が回転させられ、底板２cに固定された内歯歯車４１と噛合い回転し、遊星枠４３が出力フランジ３を伴って回転する。即ち、動力源の回転は、小径の傘歯車３２から大径の傘歯車３０を介して太陽歯車１７が回転させられると、遊星歯車４０が自転するので、遊星枠４３が公転し、この公転が出力フランジ３に回転させる。   The sun gear 17, the planetary gear 40, and the planetary frame 43 constitute a planetary gear reduction mechanism. When the sun gear 17 rotates, the planetary gear 40 is rotated by this rotation, and the internal gear fixed to the bottom plate 2c. The planetary frame 43 rotates with the output flange 3. That is, when the sun gear 17 is rotated from the small-diameter bevel gear 32 via the large-diameter bevel gear 30, the planetary gear 40 rotates, and the planetary frame 43 revolves. The output flange 3 is rotated.

前記出力フランジ３に設けてある油路４５は、凹部２０で構成する油室２０aに開口する開口端４５aを備え、この開口端４５aからの潤滑油を吐出する吐出口４６a〜４６cを有する。前記吐出口４６aは、内歯歯車４１の周囲に底板２cで構成してありベアリング４に潤滑油を供給する潤滑室４７の上部に位置しており、油室２０aからの潤滑油を潤滑室４７に供給する。また、前記吐出口４６bは、遊星歯車４０のベアリング４０aの上部に位置し遊星歯車４０と共に回転するので、ベアリング４０aに油室２０aからの潤滑油を常時供給する。さらに前記吐出口４６cは、太陽歯車１７と遊星歯車４０の噛合い部に位置し、この噛合い部と共に回転し油室２０aからの潤滑油を常時供給する。   The oil passage 45 provided in the output flange 3 includes an opening end 45a that opens to the oil chamber 20a formed by the recess 20, and has discharge ports 46a to 46c that discharge lubricating oil from the opening end 45a. The discharge port 46a is constituted by the bottom plate 2c around the internal gear 41, and is positioned above the lubrication chamber 47 for supplying the lubricant to the bearing 4. The lubrication oil from the oil chamber 20a is supplied to the lubrication chamber 47. To supply. The discharge port 46b is positioned above the bearing 40a of the planetary gear 40 and rotates together with the planetary gear 40, so that the lubricating oil from the oil chamber 20a is constantly supplied to the bearing 40a. Further, the discharge port 46c is located at the meshing portion of the sun gear 17 and the planetary gear 40, and rotates together with the meshing portion to constantly supply the lubricating oil from the oil chamber 20a.

このように、油路４５は、開口端４５aから潤滑油が供給されるとその一部は、吐出口４６aから潤滑室４７に供給され、吐出口４６bからベアリング４０aに供給され、また吐出口４６cから太陽歯車１７と遊星歯車４０の噛合い部に供給するものである。そして、吐出口４６bと吐出口４６cから滴下する潤滑油は、出力フランジ３と遊星枠４３とが常に同一位置で回転するので、太陽歯車１７と遊星枠４３との回転数が相違していても、ベアリング４０aと太陽歯車１７と遊星歯車４０との噛合い部に潤滑油は常時供給することになる。また、潤滑室４７は、内歯歯車４１の外側の周囲に設けてあり、吐出口４６aが出力フランジ３の回転に関係なく潤滑室４７の上部に位置するので、潤滑室４７には潤滑油が常時供給されることになる。   Thus, when the lubricating oil is supplied from the opening end 45a, a part of the oil passage 45 is supplied from the discharge port 46a to the lubrication chamber 47, supplied from the discharge port 46b to the bearing 40a, and discharged from the discharge port 46c. To the meshing portion of the sun gear 17 and the planetary gear 40. The lubricating oil dropped from the discharge port 46b and the discharge port 46c always rotates at the same position of the output flange 3 and the planetary frame 43. Therefore, even if the rotational speeds of the sun gear 17 and the planetary frame 43 are different. The lubricating oil is always supplied to the meshing portion of the bearing 40a, the sun gear 17, and the planetary gear 40. The lubrication chamber 47 is provided around the outside of the internal gear 41, and the discharge port 46a is positioned above the lubrication chamber 47 regardless of the rotation of the output flange 3. It will be supplied constantly.

さらに、前記吐出口４６bと吐出口４６cから滴下した潤滑油は、太陽歯車１７と遊星歯車４０の噛合い部とベアリング４０aを潤滑した後軸受保持体１３が形成する潤滑室１３bに溜まりベアリング１４、ベアリング４２を潤滑する。そして、この潤滑室１３bに貯留された潤滑油は、軸受保持体１３の上方に設けた排出孔１３aを介して大径の傘歯車３０の上面に滴下してオイルバス５に還流する   Further, the lubricating oil dropped from the discharge port 46b and the discharge port 46c is accumulated in the lubrication chamber 13b formed by the bearing holder 13 after lubricating the meshing portion of the sun gear 17 and the planetary gear 40 and the bearing 40a. Lubricate the bearing 42. Then, the lubricating oil stored in the lubricating chamber 13 b is dropped onto the upper surface of the large-diameter bevel gear 30 through the discharge hole 13 a provided above the bearing holder 13 and returns to the oil bath 5.

また、前記潤滑室４７には、底板２cに固定したパイプ５０が開口すると共に溢水窓５２を備えている。前期パイプ５０の開口端５０aの位置と溢水窓５２の下端５１の高さをほぼ同等にしてある。従って潤滑室４７には、ほぼパイプ５０の開口端５０aの高さに潤滑油が保持され常にベアリング４に潤滑油を供給する。   Further, the lubrication chamber 47 is provided with an overflow window 52 and a pipe 50 fixed to the bottom plate 2c is opened. The position of the opening end 50a of the first pipe 50 and the height of the lower end 51 of the overflow window 52 are made substantially equal. Therefore, the lubricating oil is held in the lubricating chamber 47 at substantially the height of the opening end 50 a of the pipe 50 and is always supplied to the bearing 4.

前記パイプ５０は、その下端がボス３７の油路３６に接続しており、潤滑室４７から開口端４５aを介して流出する潤滑油が油路３５を介して開口端３５aと開口端３５bからベアリング３４aとベアリング３４bに供給される。このベアリング３４aとベアリング３４bを潤滑した潤滑油は、ハウジング３３の下部に設けた排出油路３７を介して、オイルバス５へ還流する。また、潤滑室４７への潤滑油の供給が多くなり、パイプ５０から十分排出できなくなると、溢水窓５２の下端５１を経て溢水枡５３から排出油路５４を介してオイルバス５へ還流する。   The pipe 50 has a lower end connected to the oil passage 36 of the boss 37, and the lubricating oil flowing out from the lubrication chamber 47 through the opening end 45 a is bearing from the opening end 35 a and the opening end 35 b through the oil passage 35. 34a and bearing 34b. The lubricating oil that has lubricated the bearing 34 a and the bearing 34 b returns to the oil bath 5 through a discharge oil passage 37 provided in the lower portion of the housing 33. When the supply of lubricating oil to the lubrication chamber 47 increases and the pipe 50 cannot be sufficiently discharged, it returns to the oil bath 5 from the overflow tank 53 through the drain oil passage 54 via the lower end 51 of the overflow window 52.

主軸１０の下部に設けたオイルポンプ１２からの潤滑油は、潤滑油のパイプ１９から油室２０aに供給されこの油室２０aから、油路４５から吐出口４６aを経て潤滑室４７に貯留され、さらに、パイプ５０から油路３６から出油路３８を経てオイルバス５に還流し、その途中にあるベアリングに潤滑油を掛け流す。また、吐出口４６bと吐出口４６bから流出する潤滑油は、潤滑室１３ｂから排出孔１３aを経てオイルバス５に掛け流され、その経路中にあるベアリング等を潤滑する。この様に、回転数の相違する部材間に設けた油室２０aに潤滑油を供給して、この油室２０aから多方向に掛け流して大きなオイルバス５に還流する様にしたので、各部分への潤滑が適切に行き渡る。 Lubricating oil from the oil pump 12 provided at the lower portion of the main shaft 10 is supplied from the lubricating oil pipe 19 to the oil chamber 20a, and is stored in the lubricating chamber 47 from the oil chamber 20a through the oil passage 45 through the discharge port 46a. Further, the oil is recirculated from the pipe 50 through the oil passage 36 to the oil bath 5 through the oil discharge passage 38, and the lubricating oil is poured over a bearing in the middle thereof. Further, the lubricating oil flowing out from the discharge port 46b and the discharge port 46b flows into the oil bath 5 from the lubrication chamber 13b through the discharge hole 13a, and lubricates bearings and the like in the path. As described above, the lubricating oil is supplied to the oil chamber 20a provided between the members having different rotational speeds, and is circulated from the oil chamber 20a in multiple directions so as to return to the large oil bath 5. Proper lubrication.

以上の構成を有する実施例は、入力軸３１に駆動源からの回転が伝達されると、小径の傘歯車３２と大径の傘歯車３０の噛合い回転により、主軸１０が回転させられる。この主軸１０の回転は、スプライン継手１５を介して太陽歯車１７から遊星歯車４０に伝達されるので、遊星歯車４０が内歯歯車４１に噛合って自転し遊星枠４３を公転する。この遊星枠４３の公転は、遊星枠４３が出力フランジ３に連結しているので、出力フランジ３を回転する。尚、出力フランジ３の回転は、大径の傘歯車３０と小径の傘歯車３２の噛合い回転で減速され、さらに、太陽歯車１７と遊星歯車４０の噛合い回転で減速されると共に、遊星歯車４０と内歯歯車４１の噛合い回転で減速された値となる。   In the embodiment having the above configuration, when the rotation from the drive source is transmitted to the input shaft 31, the main shaft 10 is rotated by the meshing rotation of the small-diameter bevel gear 32 and the large-diameter bevel gear 30. Since the rotation of the main shaft 10 is transmitted from the sun gear 17 to the planetary gear 40 via the spline joint 15, the planetary gear 40 meshes with the internal gear 41 and rotates to revolve the planetary frame 43. The revolution of the planetary frame 43 rotates the output flange 3 because the planetary frame 43 is connected to the output flange 3. The rotation of the output flange 3 is decelerated by the meshing rotation of the large-diameter bevel gear 30 and the small-diameter bevel gear 32, and further decelerated by the meshing rotation of the sun gear 17 and the planetary gear 40, and the planetary gear. It becomes a value decelerated by the meshing rotation of 40 and the internal gear 41.

オイルバス５の潤滑油は、ケース２２の孔２５から、ネジ部２３により下方室２６に供給される。この下方室２６に供給された潤滑油は、主軸１０のパイプ１９の内部から油室２０aに流出する。油室２０aに供給された潤滑油は、油路４５から、吐出口４６aをから潤滑室４７に供給されベアリング４を潤滑ると共に、パイプ５０から油路３５を経てベアリング３４aとベアリング３４bを潤滑して出油路３８を介してオイルバス５へ還流する。
また、油路４５から吐出口４６bと吐出口４６cとから流出する潤滑油は、遊星歯車４０のベアリング４０aと遊星歯車４０と太陽歯車１７の噛合い部を潤滑した後、潤滑室１３ｂに貯留され、ベアリング１４とベアリング４２を潤滑した後排出孔１３aから大径の傘歯車３０に滴下してオイルバス５に還流する。 Lubricating oil in the oil bath 5 is supplied from the hole 25 of the case 22 to the lower chamber 26 by the screw portion 23. The lubricating oil supplied to the lower chamber 26 flows out from the inside of the pipe 19 of the main shaft 10 to the oil chamber 20a. The lubricating oil supplied to the oil chamber 20a is supplied from the oil passage 45 through the discharge port 46a to the lubrication chamber 47 and lubricates the bearing 4, and also lubricates the bearing 34a and the bearing 34b from the pipe 50 through the oil passage 35. Then, the oil flows back to the oil bath 5 through the oil discharge passage 38.
Further, the lubricating oil flowing out from the discharge port 46b and the discharge port 46c from the oil passage 45 lubricates the meshing portion of the bearing 40a of the planetary gear 40, the planetary gear 40, and the sun gear 17, and is then stored in the lubrication chamber 13b. After the bearing 14 and the bearing 42 are lubricated, the bearing 14 and the bearing 42 are dropped into the large-diameter bevel gear 30 from the discharge hole 13a and returned to the oil bath 5.
