しかしながら、こうした潤滑油案内装置では、潤滑油導入部が複数設けられている場合には、各潤滑油導入部からの潤滑油が衝突して潤滑油を円筒部の内部孔に円滑に案内することができない場合が生ずる。   However, in such a lubricating oil guide device, when a plurality of lubricating oil introduction portions are provided, the lubricating oil from each lubricating oil introduction portion collides and smoothly guides the lubricating oil to the inner hole of the cylindrical portion. There is a case that cannot be done.

本発明は上記従来の問題点に鑑み案出したものであって、回転軸の軸中心油路に潤滑油を導入する導入口に複数の導入経路から潤滑油が導入される場合であっても潤滑油を軸中心油路内に良好に案内することを目的とし、その請求項１は、回転軸の軸中心に形成された軸中心油路内に潤滑油を案内する潤滑油案内装置であって、前記軸中心油路に形成された前記潤滑油の導入口と、前記回転軸を回転可能に支承するケースの前記導入口に対応する位置に形成された潤滑油導入部と、該潤滑油導入部に潤滑油を送入する前記ケースに形成された複数の潤滑油流路と、該複数の潤滑油流路に対向して配置されて前記潤滑油導入部を仕切るとともに前記軸中心油路内に挿入された仕切り手段とを備えることである。   The present invention has been devised in view of the above-described conventional problems, and even when the lubricating oil is introduced from a plurality of introduction paths into the introduction port for introducing the lubricating oil into the axial center oil path of the rotating shaft. The first object of the present invention is to provide a lubricating oil guide device for guiding the lubricating oil into the shaft center oil passage formed at the shaft center of the rotating shaft. The lubricating oil introduction port formed in the shaft center oil passage, the lubricating oil introduction portion formed at a position corresponding to the introduction port of the case for rotatably supporting the rotating shaft, and the lubricating oil A plurality of lubricating oil passages formed in the case for feeding the lubricating oil into the introduction portion; and the plurality of lubricating oil passages arranged opposite to the plurality of lubricating oil passages to partition the lubricating oil introduction portion and the shaft center oil passage And partition means inserted in the inside.

また、請求項４は、前記仕切り板は、前記フランジ部との接続部が略Ｒ状に形成されてなることである。   According to a fourth aspect of the present invention, the partition plate is formed such that a connection portion with the flange portion is formed in a substantially R shape.

また、請求項５は、前記仕切り板は、前記対向面が前記回転軸の回転方向とは反対側に傾斜して前記複数の潤滑油流路に対向するよう配置されてなることである。   The partition plate may be arranged such that the facing surface is inclined to the opposite side of the rotation direction of the rotating shaft and faces the plurality of lubricating oil flow paths.

本発明は、回転軸の軸中心に形成された軸中心油路内に潤滑油を案内する潤滑油案内装置であって、前記軸中心油路に形成された前記潤滑油の導入口と、前記回転軸を回転可能に支承するケースの前記導入口に対応する位置に形成された潤滑油導入部と、該潤滑油導入部に潤滑油を送入する前記ケースに形成された複数の潤滑油流路と、該複数の潤滑油流路に対向して配置されて前記潤滑油導入部を仕切るとともに前記軸中心油路内に挿入された仕切り手段とを備えることにより、複数の潤滑油路から潤滑油導入部に潤滑油が導入される際に、潤滑油が衝突することなく軸中心油路内に案内される。従って、回転軸の軸中心油路に潤滑油を導入する導入口に複数の導入経路から潤滑油が導入される場合であっても、潤滑油を軸中心油路内に良好に案内することができる。   The present invention is a lubricating oil guide device that guides lubricating oil into a shaft center oil passage formed at the shaft center of a rotating shaft, the lubricating oil inlet formed in the shaft center oil passage, A lubricating oil introduction portion formed at a position corresponding to the introduction port of the case that rotatably supports the rotating shaft, and a plurality of lubricating oil flows formed in the case that feeds the lubricating oil into the lubricating oil introduction portion Lubricating from the plurality of lubricating oil passages by providing a passage and a partitioning means disposed to face the plurality of lubricating oil passages and partitioning the lubricating oil introduction portion and inserted into the shaft center oil passage. When the lubricating oil is introduced into the oil introducing portion, the lubricating oil is guided into the shaft center oil passage without colliding. Therefore, even when the lubricating oil is introduced from a plurality of introduction paths into the introduction port for introducing the lubricating oil into the shaft center oil path of the rotating shaft, the lubricant can be guided well into the shaft center oil path. it can.

また、前記仕切り手段は、前記潤滑油導入部に取り付け可能なフランジ部と、該フランジ部に垂設された仕切り板とからなることにより、フランジ部を潤滑油導入部に取り付けるだけで、フランジ部に垂設された仕切り板が複数の潤滑油流路に対向して配置されて潤滑油導入部を仕切り、更に軸中心油路内に挿入されるから、簡易な構成で軸中心油路内に潤滑油を良好に案内することができる。   Further, the partition means comprises a flange portion attachable to the lubricating oil introduction portion and a partition plate suspended from the flange portion, so that the flange portion is simply attached to the lubricating oil introduction portion.

また、前記仕切り板は、前記対向面が前記回転軸の回転方向とは反対側に傾斜して前記複数の潤滑油流路に対向するよう配置されてなることにより、潤滑油が回転軸の回転方向とは反対方向に傾斜されているから、潤滑油流路からの潤滑油が回転軸に連れ回るのを防止することができる。この結果、潤滑油が回転軸の回転により軸中心油路壁面に遠心力で張り付くのを防止できるから、潤滑油を軸中心油路内に良好に案内することができる。   Further, the partition plate is arranged so that the facing surface is inclined to the opposite side to the rotation direction of the rotating shaft and faces the plurality of lubricating oil flow paths, so that the lubricating oil rotates the rotating shaft. Since it is inclined in the direction opposite to the direction, it is possible to prevent the lubricating oil from the lubricating oil flow path from rotating around the rotating shaft. As a result, it is possible to prevent the lubricating oil from sticking to the wall surface of the shaft center oil passage by centrifugal force due to the rotation of the rotating shaft, so that the lubricating oil can be guided well into the shaft center oil passage.

以下、本発明の実施例を図面に基づいて説明する。
図１は、本発明の一実施形態としての潤滑油案内装置２０を備える変速機１の構成の概略を示す概略構成図であり、図２は、実施例である潤滑油案内装置２０周辺を拡大して示す要部拡大図である。
実施例の潤滑油案内装置２０を備える変速機１は、図１に示すように、中空構造で軸中心に潤滑油の軸中心油路２ａが形成されているとともにケース１ａにベアリング３を介して回転可能に支承された回転軸２と、この回転軸２上に配置された遊転ギヤｇを含む変速ギヤ対Ｇと遊転ギヤｇを回転軸２に選択的に固定する同期装置Ｓとから構成される変速機構ＴＭと、変速ギヤ対Ｇや図示しないディファレンシャルギヤによって掻き上げられた潤滑油を受け止めて変速機構ＴＭの各部へ潤滑油を上方から供給するオイルガータ５と、オイルガータ５から軸中心油路２ａ内に潤滑油を案内する実施例の潤滑油案内装置２０とを備える。 Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic configuration diagram showing an outline of a configuration of a transmission 1 including a lubricating oil guide device 20 as one embodiment of the present invention, and FIG. 2 is an enlarged view of the periphery of the lubricating oil guide device 20 as an embodiment. It is a principal part enlarged view shown.
As shown in FIG. 1, the transmission 1 including the lubricating oil guide device 20 according to the embodiment has a hollow structure in which an axial center oil passage 2 a for lubricating oil is formed at the center of the shaft, and a bearing 3 is interposed in the case 1 a. A rotating shaft 2 that is rotatably supported, a transmission gear pair G that includes a free rotating gear g disposed on the rotating shaft 2, and a synchronizer S that selectively fixes the free rotating gear g to the rotating shaft 2. The structured transmission mechanism TM, the oil garter 5 that receives the lubricating oil scraped up by the transmission gear pair G and a differential gear (not shown) and supplies the lubricating oil from above to the parts of the transmission mechanism TM, and the shaft from the oil garter 5 And a lubricating oil guide device 20 of the embodiment for guiding the lubricating oil into the central oil passage 2a.

実施例の潤滑油案内装置２０は、図１および図２に示すように、回転軸２の端部が挿入されて軸中心油路２ａの導入口２ｂと連通するケース１ａに形成された潤滑油導入部としての円形凹部１ｂと、オイルガータ５と円形凹部１ｂとを接続するケース１ａに形成された潤滑溝４ａと、図示しない潤滑油供給部と円形凹部１ｂとを接続するケース１ａに穿設された潤滑孔４ｂと、円形凹部１ｂに形成された円形段部１ｂ’に取り付けられて潤滑溝４ａや潤滑孔４ｂからの潤滑油を軸中心油路２ａに導くオイルチャンネル６とを備える。   As shown in FIGS. 1 and 2, the lubricating oil guide device 20 of the embodiment has a lubricating oil formed in a case 1a in which the end of the rotary shaft 2 is inserted and communicated with the inlet 2b of the shaft center oil passage 2a. A circular recess 1b as an introduction portion, a lubricating groove 4a formed in a case 1a connecting the oil garter 5 and the circular recess 1b, and a case 1a connecting a lubricant supply portion (not shown) and the circular recess 1b are formed. And an oil channel 6 that is attached to the circular step 1b ′ formed in the circular recess 1b and guides the lubricating oil from the lubricating groove 4a and the lubricating hole 4b to the shaft center oil passage 2a.

回転軸２には、軸中心油路２ａの潤滑油を変速機構ＴＭの各部、特に同期装置Ｓに供給するための供給口として複数箇所に亘って径方向貫通孔２ｃが形成されている。   The rotary shaft 2 is formed with radial through holes 2c at a plurality of locations as supply ports for supplying the lubricating oil in the shaft center oil passage 2a to each part of the speed change mechanism TM, particularly to the synchronization device S.

図３は、ケース１ａに形成された潤滑溝４ａ周辺を拡大して示す拡大正面図である。潤滑溝４ａは、図示するように、オイルガータ５の屈曲部５ａ（図中二点鎖線で示す）とベアリング３（図中二点鎖線で示す）とにより覆われて、オイルガータ５からの潤滑油を円形凹部１ｂへと導く潤滑油路４ａ’を構成する。   FIG. 3 is an enlarged front view showing the periphery of the lubricating groove 4a formed in the case 1a in an enlarged manner. As shown in the figure, the lubricating groove 4a is covered with a bent portion 5a (indicated by a two-dot chain line in the figure) and a bearing 3 (indicated by a two-dot chain line in the figure) of the oil garter 5, and lubrication from the oil garter 5 is performed. A lubricating oil passage 4a 'for guiding oil to the circular recess 1b is formed.

図４は、オイルチャンネル６の外観を示す外観図であり、図５は、オイルチャンネル６を円形段部１ｂ’に取り付けた状態を正面からみた状態図である。
オイルチャンネル６は、図４に示すように、円形段部１ｂ’に取り付けるためのベースとしてのフランジ部６１と、このフランジ部６１から直角方向に延びる仕切り板６２とから構成されており、仕切り板６２が、図５に示すように、回転軸２の回転方向とは反対方向に傾斜した状態で軸中心油路２ａ内に挿入される。即ち、仕切り板６２によって円形凹部１ｂを潤滑油路４ａ’側と潤滑孔４ｂ側とに仕切って潤滑油を軸中心油路２ａへ案内する経路を構成する。 FIG. 4 is an external view showing the external appearance of the oil channel 6, and FIG. 5 is a state view of the state in which the oil channel 6 is attached to the circular step portion 1b ′ as viewed from the front.
As shown in FIG. 4, the oil channel 6 includes a flange portion 61 as a base for attaching to the circular step portion 1 b ′, and a partition plate 62 extending in a direction perpendicular to the flange portion 61. As shown in FIG. 5, 62 is inserted into the shaft center oil passage 2 a while being inclined in a direction opposite to the rotation direction of the rotary shaft 2. That is, the partition plate 62 divides the circular recess 1b into the lubricating oil passage 4a 'side and the lubricating hole 4b side, thereby constituting a route for guiding the lubricating oil to the shaft center oil passage 2a.

仕切り板６２は、フランジ部６１から滑らかな形状、例えば、Ｒ形状でもって連続的に一体形成されており、先端にいくに伴い厚みが漸減する傾斜状となっている。即ち、仕切り板６２は、仕切り板６２の潤滑油路４ａ’に対向する対向面６２ａと潤滑孔４ｂに対向する対向面６２ｂとが、先端に向かうほど接近するような傾斜状に形成されている。また、仕切り板６２は、円形凹部１ｂを潤滑油路４ａ’側と潤滑孔４ｂ側とに仕切る。   The partition plate 62 is integrally formed continuously from the flange portion 61 with a smooth shape, for example, an R shape, and has an inclined shape in which the thickness gradually decreases toward the tip. That is, the partition plate 62 is formed in an inclined shape such that the facing surface 62a facing the lubricating oil passage 4a ′ of the partition plate 62 and the facing surface 62b facing the lubricating hole 4b approach each other toward the tip. . The partition plate 62 partitions the circular recess 1b into the lubricating oil passage 4a 'side and the lubricating hole 4b side.

次に、こうして構成された実施例の潤滑油案内装置２０の動作に伴って、回転軸２の軸中心油路２ａ内に案内される潤滑油の動きについて説明する。
変速ギヤ対Ｇや図示しないディファレンシャルギヤによって掻き上げられてオイルガータ５に受け止められた潤滑油は、上方から変速機構ＴＭの各部へ供給されながらオイルガータ５を屈曲部５ａに向かって流れる。屈曲部５ａまで流れてきた潤滑油は、屈曲部５ａによって潤滑油路４ａ’に導かれ、潤滑油路４ａ’を通って上方から円形凹部１ｂに供給される。一方、図示しない潤滑油供給部からは、潤滑孔４ｂを介して下方から円形凹部１ｂに潤滑油が供給される。このとき、円形凹部１ｂがオイルチャンネル６の仕切り板６２により潤滑油路４ａ’側と潤滑油孔４ｂ側とに仕切られているから、潤滑油路４ａ’から供給される潤滑油と潤滑油孔４ｂから供給される潤滑油が互いに衝突することがない。 Next, the movement of the lubricating oil guided into the shaft center oil passage 2a of the rotating shaft 2 in accordance with the operation of the lubricating oil guiding apparatus 20 of the embodiment configured as described above will be described.
The lubricating oil scraped up by the transmission gear pair G and a differential gear (not shown) and received by the oil garter 5 flows through the oil garter 5 toward the bent portion 5a while being supplied to each part of the transmission mechanism TM from above. The lubricating oil that has flowed to the bent portion 5a is guided to the lubricating oil passage 4a ′ by the bent portion 5a, and is supplied to the circular concave portion 1b from above through the lubricating oil passage 4a ′. On the other hand, from a lubricating oil supply unit (not shown), the lubricating oil is supplied from below to the circular recess 1b through the lubricating hole 4b. At this time, since the circular recess 1b is partitioned by the partition plate 62 of the oil channel 6 into the lubricating oil passage 4a ′ side and the lubricating oil hole 4b side, the lubricating oil and the lubricating oil hole supplied from the lubricating oil passage 4a ′. The lubricating oil supplied from 4b does not collide with each other.

そして、潤滑油路４ａ’によって上方から円形凹部１ｂに供給された潤滑油は、仕切り板６２の対向面６２ａによって軸中心油路２ａに案内されるとともに、潤滑孔４ｂによって下方から円形凹部１ｂに供給された潤滑油は、仕切り板６２の対向面６２ｂによって軸中心油路２ａに案内される。このとき、仕切り板６２とフランジ部６１との接続部のＲ形状によって潤滑油の流れの向きを円滑に軸方向に変えることができるとともに、仕切り板６２の傾斜によって円滑に軸中心油路２ａ内に潤滑油を案内することができる。
また、軸中心油路２ａ内に案内された潤滑油は、遠心力により軸中心油路２ａ壁面に張り付いて回転軸２の回転に連れまわろうとするが、仕切り板６２が回転軸２の回転方向とは反対方向に傾斜した状態で軸中心油路２ａ内に挿入されていることにより、潤滑油の回転軸２との連れ回りを積極的に阻止する。これにより、より良好に軸中心油路２ａ内に潤滑油を案内することができる。 The lubricating oil supplied from above to the circular recess 1b by the lubricating oil passage 4a 'is guided to the axial center oil passage 2a by the facing surface 62a of the partition plate 62, and from below to the circular recess 1b by the lubricating hole 4b. The supplied lubricating oil is guided to the shaft center oil passage 2 a by the facing surface 62 b of the partition plate 62. At this time, the flow direction of the lubricating oil can be smoothly changed to the axial direction by the R shape of the connecting portion between the partition plate 62 and the flange portion 61, and smoothly in the shaft center oil passage 2 a by the inclination of the partition plate 62. It is possible to guide the lubricating oil.
Further, the lubricating oil guided in the shaft center oil passage 2a sticks to the wall surface of the shaft center oil passage 2a by centrifugal force and tries to rotate with the rotation shaft 2, but the partition plate 62 rotates the rotation shaft 2. By being inserted into the shaft center oil passage 2a while being inclined in the direction opposite to the direction, the accompanying rotation of the lubricating oil with the rotating shaft 2 is actively prevented. As a result, the lubricating oil can be guided into the shaft center oil passage 2a better.

こうして軸中心油路２ａ内に案内された潤滑油は、回転軸２の回転による遠心力により径方向貫通孔２ｃから流出して変速機構ＴＭの各部、特に同期装置Ｓの潤滑を行う。   The lubricating oil thus guided into the shaft center oil passage 2a flows out of the radial through hole 2c by the centrifugal force caused by the rotation of the rotating shaft 2 and lubricates each part of the speed change mechanism TM, particularly the synchronizing device S.

以上説明した実施例１の潤滑油案内装置２０によれば、潤滑油路４ａ’から潤滑油導入部としての円形凹部１ｂを介して軸中心油路２ａに潤滑油を案内する経路と、潤滑孔４ｂから潤滑油導入部としての円形凹部１ｂを介して軸中心油路２ａに潤滑油を供給する経路とをオイルチャンネル６の仕切り板６２により仕切るから、潤滑油路４ａ’から供給される潤滑油と潤滑孔４ｂから供給される潤滑油とが互いに衝突することがない。この結果、潤滑油を軸中心油路２ａ内に良好に案内することができる。   According to the lubricating oil guide device 20 of the first embodiment described above, the path for guiding the lubricating oil from the lubricating oil path 4a ′ to the shaft center oil path 2a via the circular recess 1b as the lubricating oil introduction section, and the lubricating hole Since the passage for supplying the lubricating oil to the shaft center oil passage 2a is partitioned by the partition plate 62 of the oil channel 6 through the circular recess 1b as the lubricating oil introduction portion from 4b, the lubricating oil supplied from the lubricating oil passage 4a ' And the lubricating oil supplied from the lubricating hole 4b do not collide with each other. As a result, the lubricating oil can be favorably guided into the shaft center oil passage 2a.

また、仕切り板６２とフランジ部６１との接続部をＲ形状に形成するから、潤滑油の流れの向きを円滑に軸方向に変えることができる。さらに、仕切り板６２を対向面６２ａと対向面６２ｂとが先端に向かうほど接近するような傾斜状に形成するから、潤滑油を円滑に軸中心油路２ａ内に案内することができる。また、仕切り板６２を回転軸２の回転方向とは反対方向に傾斜した状態で軸中心油路２ａ内に挿入するから、遠心力により軸中心油路２ａの壁面に張り付いて回転軸２の回転に連れまわろうとする潤滑油の回転軸２との連れ回りを積極的に阻止することができる。この結果、より良好に軸中心油路２ａ内に潤滑油を案内することができる。   Moreover, since the connection part of the partition plate 62 and the flange part 61 is formed in R shape, the direction of the flow of lubricating oil can be smoothly changed to an axial direction. Furthermore, since the partition plate 62 is formed in an inclined shape such that the opposing surface 62a and the opposing surface 62b approach each other toward the tip, the lubricating oil can be smoothly guided into the shaft center oil passage 2a. Further, since the partition plate 62 is inserted into the shaft center oil passage 2a while being inclined in a direction opposite to the rotation direction of the rotation shaft 2, the partition plate 62 is attached to the wall surface of the shaft center oil passage 2a by centrifugal force. It is possible to positively prevent the lubricating oil that is about to rotate with the rotating shaft 2. As a result, it is possible to better guide the lubricating oil into the shaft center oil passage 2a.

実施例１の潤滑油案内装置２０では、仕切り板６２は、フランジ部６１からＲ形状でもって連続的に一体形成されているものとしたが、フランジ部６１から滑らかな形状でもって連続していればＲ形状に限らず如何なる形状であっても良い。   In the lubricating oil guide device 20 of the first embodiment, the partition plate 62 is continuously formed integrally with the flange portion 61 with the R shape, but may be continuous with the flange portion 61 with a smooth shape. For example, the shape is not limited to the R shape and may be any shape.

実施例１の潤滑油案内装置２０では、仕切り板６２は、フランジ部６１からＲ形状でもって連続的に一体形成されているものとしたが、潤滑油路４ａ’や潤滑孔４ｂからの潤滑油を衝突させることなく軸中心油路２ａ内に案内できれば良く、フランジ部６１から直角に連続するものであっても構わない。   In the lubricating oil guiding apparatus 20 of the first embodiment, the partition plate 62 is continuously formed integrally with the flange portion 61 with an R shape. However, the lubricating oil from the lubricating oil passage 4a ′ and the lubricating hole 4b is used. As long as it can be guided into the shaft center oil passage 2a without colliding with each other, it may be continuous from the flange portion 61 at a right angle.

実施例１の潤滑油案内装置２０では、仕切り板６２は、対向面６２ａと対向面６２ｂとが、先端に向かうほど接近するような傾斜状に形成されているものとしたが、対向面６２ａと対向面６２ｂとが平行に形成されているものであっても構わない。   In the lubricant guide device 20 of the first embodiment, the partition plate 62 is formed in an inclined shape such that the facing surface 62a and the facing surface 62b approach each other toward the tip, but the facing surface 62a The opposing surface 62b may be formed in parallel.

実施例１の潤滑油案内装置２０では、仕切り板６２は、回転軸２の回転方向とは反対方向に傾斜した状態で軸中心油路２ａ内に挿入されるものとしたが、仕切り板６２は、回転軸２の回転方向に対して傾斜しない状態、即ち、回転軸２の軸線方向に水平な状態で軸中心油路２ａ内に挿入されるものとしたり、回転軸２の回転方向と同方向に傾斜した状態で軸中心油路２ａ内に挿入されるものしても構わない。   In the lubricating oil guide apparatus 20 according to the first embodiment, the partition plate 62 is inserted into the shaft center oil passage 2a while being inclined in a direction opposite to the rotation direction of the rotary shaft 2, but the partition plate 62 is It is assumed that it is inserted into the shaft center oil passage 2a in a state where it is not inclined with respect to the rotational direction of the rotary shaft 2, that is, in a state horizontal to the axial direction of the rotary shaft 2, or the same direction as the rotational direction of the rotary shaft 2 It may be inserted into the shaft center oil passage 2a in a state of being inclined to the center.

次に、本発明の第２実施例の潤滑油案内装置１２０について説明する。
図６は、第２実施例である潤滑油案内装置１２０の構成の概略を示す構成図である。第２実施例の潤滑油案内装置１２０を備える変速機１Ａは、潤滑油案内装置２０を潤滑油案内装置１２０に変えた点を除いて第１実施例の潤滑油案内装置２０を備える変速機１と同一の構成をしている。従って、第２実施例の変速機１Ａの構成のうち第１実施例の変速機１と同一の構成については同一の符号を付し、その説明を省略する。 Next, the lubricating oil guide device 120 of the second embodiment of the present invention will be described.
FIG. 6 is a configuration diagram showing an outline of the configuration of the lubricating oil guide device 120 according to the second embodiment. A transmission 1A including the lubricant guide device 120 of the second embodiment is a transmission 1 including the lubricant guide device 20 of the first embodiment, except that the lubricant guide device 20 is changed to the lubricant guide device 120. It has the same configuration as Therefore, in the configuration of the transmission 1A of the second embodiment, the same components as those of the transmission 1 of the first embodiment are denoted by the same reference numerals and description thereof is omitted.

第２実施例の潤滑油案内装置１２０は、図示するように、回転軸２の端部が挿入されて軸中心油路２ａの導入口２ｂと連通するケース１ａに形成された潤滑油導入部としての円形凹部１ｂに潤滑油を供給するケース１ａに形成された４つの潤滑油路１４ａ，１４ｂ，１４ｃ，１４ｄと、円形凹部１ｂに形成された円形段部１ｂ’に取り付けられて４つの潤滑油路１４ａ，１４ｂ，１４ｃ，１４ｄからの潤滑油を軸中心油路２ａに導くオイルチャンネル１６とを備える。   As shown in the drawing, the lubricating oil guiding device 120 of the second embodiment is a lubricating oil introducing portion formed in the case 1a in which the end portion of the rotating shaft 2 is inserted and communicated with the introducing port 2b of the axial center oil passage 2a. The four lubricating oil passages 14a, 14b, 14c, 14d formed in the case 1a for supplying the lubricating oil to the circular concave portion 1b and the four circular step portions 1b 'formed in the circular concave portion 1b are provided. And an oil channel 16 for guiding lubricating oil from the paths 14a, 14b, 14c, and 14d to the shaft center oil path 2a.

オイルチャンネル１６は、図示するように、円形段部１ｂ’に取り付けるためのベースとしてのフランジ部６１０と、このフランジ部６１０から直角方向に延びる仕切り板６２０とから構成されている。仕切り板６２０は、互いにほぼ直角状に交わって十字状をなす仕切り板６２０ａと仕切り板６２０ｂとから構成されており、仕切り板６２０ａと仕切り板６２０ｂとによって、円形凹部１ｂを各潤滑油路１４ａ，１４ｂ，１４ｃ，１４ｄに対応した４つの室に仕切って潤滑油を軸中心油路２ａへ案内する経路を構成する。   As shown in the figure, the oil channel 16 includes a flange portion 610 as a base for attaching to the circular step portion 1 b ′, and a partition plate 620 extending from the flange portion 610 in a right angle direction. The partition plate 620 is composed of a partition plate 620a and a partition plate 620b that cross each other substantially at right angles to form a cross shape. A path for guiding the lubricating oil to the shaft center oil path 2a is configured by partitioning into four chambers corresponding to 14b, 14c, and 14d.

次に、こうして構成された実施例２の潤滑油案内装置１２０の動作に伴って、回転軸２の軸中心油路２ａ内に案内される潤滑油の動きについて説明する。
図示しない潤滑油供給部から４つの潤滑油路１４ａ，１４ｂ，１４ｃ，１４ｄを介して円形凹部１ｂに潤滑油が供給される。円形凹部１ｂは、オイルチャンネル１６の仕切り板６２０ａおよび仕切り板６２０ｂにより４つの潤滑油路１４ａ，１４ｂ，１４ｃ，１４ｄに対応した室に仕切られているため、各潤滑油路１４ａ，１４ｂ，１４ｃ，１４ｄから供給される潤滑油は互いに衝突することなく、仕切り板６２０ａや仕切り板６２０ｂによって良好に軸中心油路２ａ内に案内される。 Next, the movement of the lubricating oil guided into the shaft center oil passage 2a of the rotating shaft 2 in accordance with the operation of the lubricating oil guiding apparatus 120 of the second embodiment configured as described above will be described.
Lubricating oil is supplied from a lubricating oil supply unit (not shown) to the circular recess 1b through the four lubricating oil passages 14a, 14b, 14c, and 14d. Since the circular recess 1b is partitioned into chambers corresponding to the four lubricating oil passages 14a, 14b, 14c, and 14d by the partition plate 620a and the partition plate 620b of the oil channel 16, each of the lubricating oil passages 14a, 14b, 14c, The lubricating oil supplied from 14d does not collide with each other, and is well guided into the shaft center oil passage 2a by the partition plate 620a and the partition plate 620b.

こうして軸中心油路２ａ内に案内された潤滑油は、回転軸２の回転による遠心力により径方向貫通孔２ｃから流出して変速機構ＴＭの各部、特に同期装置Ｓの潤滑を行う。   The lubricating oil thus guided into the shaft center oil passage 2a flows out of the radial through hole 2c by the centrifugal force generated by the rotation of the rotating shaft 2 and lubricates each part of the speed change mechanism TM, particularly the synchronizing device S.

以上説明した実施例２の潤滑油案内装置１２０によれば、潤滑油導入部としての円形凹部１ｂを仕切り板６２０ａと仕切り板６２０ｂとにより４つの潤滑油路１４ａ，１４ｂ，１４ｃ，１４ｄに対応した室に仕切るから、４つの潤滑油路１４ａ，１４ｂ，１４ｃ，１４ｄから供給される潤滑油が互いに衝突することがない。この結果、潤滑油を軸中心油路２ａ内に良好に案内することができる。   According to the lubricating oil guide device 120 of the second embodiment described above, the circular concave portion 1b as the lubricating oil introduction portion corresponds to the four lubricating oil passages 14a, 14b, 14c, and 14d by the partition plate 620a and the partition plate 620b. Since the chambers are partitioned, the lubricants supplied from the four lubricant passages 14a, 14b, 14c, and 14d do not collide with each other. As a result, the lubricating oil can be favorably guided into the shaft center oil passage 2a.

実施例２の潤滑油案内装置１２０では、４つの潤滑油路１４ａ，１４ｂ，１４ｃ，１４ｄから軸中心油路２ａ内に潤滑油を案内するものとしたが、軸中心油路２ａ内に潤滑油を供給するための潤滑油路の数はいくつであっても良く、この場合、円形凹部１ｂを潤滑油路の数に対応した室に仕切るよう仕切り板６２０を構成するものとすれば良い。   In the lubricating oil guide device 120 of the second embodiment, the lubricating oil is guided from the four lubricating oil passages 14a, 14b, 14c, and 14d into the shaft center oil passage 2a. However, the lubricating oil is introduced into the shaft center oil passage 2a. Any number of lubricating oil passages may be provided, and in this case, the partition plate 620 may be configured to partition the circular recess 1b into chambers corresponding to the number of lubricating oil passages.

実施例１，２の潤滑油案内装置２０，１２０では、仕切り板６２は、フランジ部６１に一体形成されているものとしたが、別体で形成されていても構わない。   In the lubricating oil guide devices 20 and 120 of the first and second embodiments, the partition plate 62 is formed integrally with the flange portion 61, but may be formed separately.

以上、本発明の実施の形態について実施例を用いて説明したが、本発明はこうした実施例に限定されるものではなく、本発明の要旨を逸脱しない範囲内において、種々なる形態で実施し得ることは勿論である。   As mentioned above, although embodiment of this invention was described using the Example, this invention is not limited to such an Example, In the range which does not deviate from the summary of this invention, it can implement with a various form.
