Description

本発明は、自動車の変速機などにおける回転軸に設けた部材への潤滑油供給装置、特に回転軸の外周面に設けた部材を中心孔内に供給した潤滑油により潤滑するようにした回転軸に設けた部材への潤滑油供給装置に関する。   The present invention relates to a lubricating oil supply device for a member provided on a rotating shaft in an automobile transmission or the like, and in particular, a rotating shaft adapted to lubricate a member provided on the outer peripheral surface of the rotating shaft with lubricating oil supplied into a central hole. It is related with the lubricating oil supply apparatus to the member provided in.

この種の回転軸に設けた部材への潤滑油供給装置としては、例えば特許文献１に記載された技術がある。図２はこの特許文献１とほゞ同じ技術を示すものであり、変速機ハウジング１０内に互いに平行に回転自在に支持した２本の回転軸２０，２４には、互いに噛合される複数対の変速歯車２６ａ，２６ｂ、２７ａ，２７ｂ、２８ａ，２８ｂ及び２９ａ，２９ｂが設けられ、回転軸２０には第１及び第２変速クラッチ３０，４０が設けられている。回転軸２０には、その中心孔２１と外周面２０ａの間に、各変速歯車２７ａ，２８ａ，２９ａの軸受部ならびに第１及び第２変速クラッチ３０，４０に潤滑油を供給する放射方向の分配孔２１ａ〜２１ｄが形成され、フランジ部２３ａがハウジング１０に取り付けられた潤滑油送入部材２３のパイプ部２３ｂは回転軸２０の中心孔２１内に挿入され、その先端は複数の分配孔２１ａ〜２１ｄのうち回転軸２０の一端面２０ｂに最も近い第４分配孔２１ｄよりも中心孔２１の奥側に延長配置されている。   As an apparatus for supplying lubricating oil to a member provided on this type of rotating shaft, for example, there is a technique described in Patent Document 1. FIG. 2 shows substantially the same technology as that of Patent Document 1, and a plurality of pairs of gears meshed with each other are provided on two rotary shafts 20 and 24 that are rotatably supported in parallel in the transmission housing 10. Transmission gears 26a, 26b, 27a, 27b, 28a, 28b and 29a, 29b are provided, and the rotary shaft 20 is provided with first and second transmission clutches 30, 40. The rotary shaft 20 has a radial distribution between the center hole 21 and the outer peripheral surface 20a for supplying lubricating oil to the bearing portions of the transmission gears 27a, 28a, and 29a and the first and second transmission clutches 30 and 40. The pipe portion 23b of the lubricating oil feeding member 23 in which the holes 21a to 21d are formed and the flange portion 23a is attached to the housing 10 is inserted into the center hole 21 of the rotating shaft 20, and the tip thereof is a plurality of distribution holes 21a to 21a. 21d, the fourth distribution hole 21d closest to the one end surface 20b of the rotating shaft 20 is extended and arranged on the back side of the center hole 21.

ハウジング１０内で撹拌される潤滑油は導入通路（図示省略）を介してハウジング１０とフランジ部２３ａの間の空間Ｓに送り込まれ、パイプ部２３ｂから矢印ａに示すように中心孔２１内に放出される。放出された潤滑油は中心孔２１の奥に向かう流れと、パイプ部２３ｂと中心孔２１の間を通る流れに分かれ、前者は全て分配孔２１ａ〜２１ｃに供給され、後者は一部が分配孔２１ｄに供給されて残りは矢印ｄに示すように、回転軸２０の一端面２０ｂの開口からハウジング１０内に排出される。これにより、各分配孔２１ａ〜２１ｄへの潤滑油供給量を可及的に均一にすることができる。
特公平３−４３５１８号公報（第３欄の第１１行〜第１６行、第５欄の第２２行〜第６欄の第１４行、図３）。 Lubricating oil stirred in the housing 10 is fed into the space S between the housing 10 and the flange portion 23a through an introduction passage (not shown), and discharged from the pipe portion 23b into the center hole 21 as indicated by an arrow a. Is done. The discharged lubricating oil is divided into a flow toward the back of the center hole 21 and a flow passing between the pipe portion 23b and the center hole 21. The former is all supplied to the distribution holes 21a to 21c, and the latter is partially distributed. The remainder is supplied to 21d and discharged from the opening of the one end face 20b of the rotating shaft 20 into the housing 10 as shown by the arrow d.

Japanese Examined Patent Publication No. 3-43518 (11th line to 16th line in the third column, 22nd line to 14th line in the fifth column, 14th line, FIG. 3).

しかしながら上述した特許文献１の技術では、潤滑油送入部材２３のパイプ部２３ｂから中心孔２１内に放出された潤滑油のうちパイプ部２３ｂと中心孔２１の間を通るものの一部は第４分配孔２１ｄを介して第２変速クラッチ４０に供給されるが、残りは中心孔２１の内面に沿って回転軸２０の一端面２０ｂ側に流れて潤滑に使用されることなく一端面２０ｂに形成された開口からハウジング１０内に排出されるので、潤滑に使用される潤滑油量が減少して作動条件によっては潤滑不足が生じるという問題がある。これを解決する手段としてはパイプ部２３ｂと中心孔２１の間の隙間を減少させ、また螺旋溝により排出とは逆向きの流れを筒部２３ｂと中心孔２１の間に発生させる等の対策が考えられるが、加工精度及び組立精度を高める必要があるので製造コストが増大するという別の問題を生じる。本発明はこのような各問題を解決することを目的とする。   However, in the technique of Patent Document 1 described above, a part of the lubricating oil discharged from the pipe portion 23b of the lubricating oil feeding member 23 into the central hole 21 passes between the pipe portion 23b and the central hole 21 is the fourth. It is supplied to the second speed change clutch 40 through the distribution hole 21d, but the remainder flows along the inner surface of the center hole 21 toward the one end surface 20b of the rotary shaft 20 and is formed on the one end surface 20b without being used for lubrication. Since it is discharged into the housing 10 from the opened opening, there is a problem in that the amount of lubricating oil used for lubrication decreases and insufficient lubrication occurs depending on operating conditions. As means for solving this, there are measures such as reducing the gap between the pipe portion 23b and the central hole 21 and generating a flow opposite to the discharge between the cylindrical portion 23b and the central hole 21 by a spiral groove. Though conceivable, it is necessary to increase the processing accuracy and the assembly accuracy, which causes another problem that the manufacturing cost increases. The object of the present invention is to solve each of these problems.

このために、本発明による回転軸に設けた部材への潤滑油供給装置は、ハウジング内にほゞ水平に回転自在に回転軸を支持し、回転軸に同軸的に形成した中心孔を回転軸の一端面に開口させ、回転軸の一端面と対向するハウジングの内面に取り付けられた潤滑油送入部材の導入部を中心孔に一端面側から挿入して中心孔内に潤滑油を送り込み、中心孔から回転軸の外周面に向かって放射方向に形成した複数の分配孔により中心孔内に送り込まれた潤滑油を回転軸の外周面に設けた部材に供給するようにした回転軸に設けた部材への潤滑油供給装置において、回転軸の一端面側となる中心孔の内面には相当な軸線方向範囲にわたり環状凹部を形成し、この環状凹部の底面は一端面から離れるにつれて次第に径が増大するテーパ面状としたことを特徴とするものである。   For this purpose, the lubricating oil supply device to the member provided on the rotating shaft according to the present invention supports the rotating shaft so as to be rotatable almost horizontally in the housing, and has a central hole formed coaxially with the rotating shaft. The lubricating oil feeding member introduced to the center hole is inserted into the center hole from one end surface side, and the lubricating oil is fed into the center hole. Provided on the rotating shaft so that the lubricating oil fed into the central hole by a plurality of distribution holes formed radially from the central hole toward the outer peripheral surface of the rotating shaft is supplied to the member provided on the outer peripheral surface of the rotating shaft. In the apparatus for supplying lubricating oil to the members, an annular recess is formed in the inner surface of the central hole on the one end surface side of the rotating shaft over a considerable axial range, and the diameter of the bottom surface of the annular recess gradually increases as the distance from the one end surface increases. Increased taper surface It is an butterfly.

前項に記載の回転軸に設けた部材への潤滑油供給装置において、潤滑油送入部材の導入部は、環状凹部の範囲よりも奥まで突出していることが好ましい。   In the lubricating oil supply device to the member provided on the rotating shaft described in the preceding paragraph, it is preferable that the introduction portion of the lubricating oil feeding member protrudes farther than the range of the annular recess.

前２項に記載の回転軸に設けた部材への潤滑油供給装置において、複数の分配孔の一部は、環状凹部の底面の径が最大となる位置付近に形成されていることが好ましい。   In the lubricating oil supply apparatus for a member provided on the rotary shaft described in the preceding item 2, it is preferable that a part of the plurality of distribution holes is formed in the vicinity of a position where the diameter of the bottom surface of the annular recess becomes maximum.

前３項に記載の回転軸に設けた部材への潤滑油供給装置において、潤滑油送入部材は、回転軸の一端面と対向するハウジングの内面に取り付けられてこの内面との間に空間を形成するフランジ部と、一端がフランジ部に連結されて空間に連通されフランジ部から略直角に延びて環状凹部内に挿入される筒状の導入部からなり、ハウジング内で撹拌される潤滑油がハウジングとフランジの間の空間内に導入されて導入部から中心孔内に送り込まれるようにすることが好ましい。   In the lubricating oil supply device to the member provided on the rotating shaft according to the preceding item 3, the lubricating oil feeding member is attached to the inner surface of the housing facing the one end surface of the rotating shaft, and a space is formed between the inner surface and the inner surface. The lubricating oil that is formed in the housing is composed of a flange portion to be formed and a cylindrical introduction portion that is connected to the flange portion at one end, communicates with the space, extends from the flange portion at a substantially right angle, and is inserted into the annular recess. It is preferable to be introduced into the space between the housing and the flange so as to be fed into the central hole from the introduction portion.

前４項に記載の回転軸に設けた部材への潤滑油供給装置において、回転軸の外周面には変速歯車を回転自在に支持するとともに変速歯車を回転軸に離脱可能に連結する変速クラッチを設け、分配孔は変速歯車および変速クラッチに潤滑油を供給することが好ましい。   In the lubricating oil supply device to the member provided on the rotating shaft according to the preceding item 4, a transmission clutch that rotatably supports the transmission gear and that removably connects the transmission gear to the rotating shaft is provided on the outer peripheral surface of the rotation shaft. The provided and distributing hole preferably supplies lubricating oil to the transmission gear and the transmission clutch.

上述のように、請求項１の発明によれば、回転軸の一端面側となる中心孔の内面には相当な軸線方向範囲にわたり環状凹部を形成し、この環状凹部の底面は一端面から離れるにつれて次第に径が増大するテーパ面状としたので、中心孔の内面に沿って回転軸の一端面側に流れて一端面に形成された開口からハウジング内に排出されようとする潤滑油は、回転軸の回転により生じる遠心力とテーパ面の作用により、回転軸の一端面から離れる向きに戻されて一端面からハウジング内に排出されようとする潤滑油が減少し、また潤滑油送入部材が取り付けられるハウジングの内面あるいは潤滑油送入部材の取付部分に沿って流れ落ちる潤滑油の一部も回転軸の一端面に形成された開口からテーパ面に沿って環状凹部内に吸い込まれる。これにより中心孔内に保持される潤滑油量が増大するので、潤滑不足が生じ難くなる。また、潤滑油送入部材の導入部と中心孔の間の隙間を減少させる必要はなく、中心孔の加工精度や潤滑油送入部材の加工精度及び取付精度を高める必要はないので、製造コストが増大することもない。   As described above, according to the first aspect of the present invention, the annular recess is formed in the inner surface of the central hole on the one end face side of the rotating shaft over a considerable axial range, and the bottom face of the annular recess is separated from the one end face. Since the tapered surface gradually increases in diameter as the lubricating oil flows to the one end surface side of the rotating shaft along the inner surface of the center hole and is about to be discharged into the housing from the opening formed in the one end surface, the lubricating oil rotates. Due to the centrifugal force generated by the rotation of the shaft and the action of the tapered surface, the lubricating oil that is returned to the direction away from the one end surface of the rotating shaft and is discharged from the one end surface into the housing is reduced, and the lubricating oil feeding member is A part of the lubricating oil that flows along the inner surface of the housing to be attached or the attaching portion of the lubricating oil feeding member is also sucked into the annular recess along the tapered surface from the opening formed at one end face of the rotating shaft. As a result, the amount of lubricating oil retained in the center hole is increased, so that insufficient lubrication is less likely to occur. In addition, it is not necessary to reduce the gap between the introduction portion of the lubricating oil feeding member and the center hole, and it is not necessary to increase the processing accuracy of the central hole and the processing accuracy and mounting accuracy of the lubricating oil feeding member. Does not increase.

潤滑油送入部材の導入部が環状凹部の範囲よりも奥まで突出している請求項２の発明によれば、潤滑油送入部材の筒部から中心孔内に放出された潤滑油が環状凹部内に直接入ることはないので、中心孔の奥部に形成された分配孔にも充分に潤滑油が分配される。従って前項に記載の効果に加えて、中心孔の奥部に形成された分配孔に連通される部材に潤滑不足が生じるおそれが減少する。   According to the second aspect of the present invention, the introduction portion of the lubricating oil feeding member protrudes deeper than the range of the annular recessed portion. The lubricating oil discharged from the cylindrical portion of the lubricating oil feeding member into the central hole is the annular recessed portion. Since the oil does not enter directly into the inside, the lubricating oil is sufficiently distributed also to the distribution hole formed in the inner part of the center hole. Therefore, in addition to the effects described in the previous section, the risk of insufficient lubrication in the member communicating with the distribution hole formed in the inner part of the center hole is reduced.

複数の分配孔の一部は、環状凹部の底面の径が最大となる位置付近に形成されている請求項３の発明によれば、前各項に記載の効果に加えて、そのような一部の分配孔に連通される部材に潤滑不足が生じるおそれも減少する。   According to the invention of claim 3, a part of the plurality of distribution holes is formed in the vicinity of the position where the diameter of the bottom surface of the annular recess is maximized. The risk of insufficient lubrication in the member communicating with the distribution hole of the portion is also reduced.

潤滑油送入部材は、回転軸の一端面と対向するハウジングの内面に取り付けられてこの内面との間に空間を形成するフランジ部と、一端がフランジ部に連結されて空間に連通されフランジ部から略直角に延びて環状凹部内に挿入される筒状の導入部からなり、ハウジング内で撹拌される潤滑油がハウジングとフランジの間の空間内に導入されて導入部から中心孔内に送り込まれるようにした請求項４の発明によれば、前各項に記載の効果に加えて、潤滑油を供給するポンプを設ける必要がないので回転軸に設けた部材への潤滑油供給装置の構造を簡略化して製造コストを少なくすることができる。   The lubricating oil feeding member is attached to the inner surface of the housing opposite to one end surface of the rotating shaft and forms a space between the inner surface and one end connected to the flange portion and communicated with the space. It consists of a cylindrical introduction part that extends substantially at a right angle and is inserted into an annular recess. Lubricating oil that is agitated in the housing is introduced into the space between the housing and the flange and fed into the center hole from the introduction part According to the fourth aspect of the invention, in addition to the effects described in the preceding paragraphs, there is no need to provide a pump for supplying the lubricating oil, so the structure of the lubricating oil supply device to the member provided on the rotating shaft Can be simplified and the manufacturing cost can be reduced.

回転軸の外周面には変速歯車を回転自在に支持するとともに変速歯車を回転軸に離脱可能に連結する変速クラッチを設け、分配孔は変速歯車および変速クラッチに潤滑油を供給するようにした請求項５の発明によれば、前各項の効果を有する変速機を得ることができる。   A transmission clutch is provided on the outer peripheral surface of the rotation shaft so as to rotatably support the transmission gear and removably connect the transmission gear to the rotation shaft, and the distribution hole supplies lubricating oil to the transmission gear and the transmission clutch. According to the invention of item 5, a transmission having the effects of the preceding items can be obtained.

入力軸２０とともに回転するスリーブ４２が、環状溝４２ｂに係合されたシフトフォーク（図示省略）により、図示の中立位置から右向きにシフトされれば、第１シフティングキースプリング４８を介してアウタリング４６が右向きに押され、アウタリング４６とミドルリング４５とインナリング４４が各コーン面とコーン穴により摩擦係合されて第５速駆動歯車２９ａが入力軸２０と同期された後、第５速駆動歯車２９ａの外歯スプライン４３がスリーブ４２の内歯スプライン４２ａと係合され、第５速駆動歯車２９ａは入力軸２０と連結されて第５速段が形成される。この状態からスリーブ４２が中立位置に戻されれば、第５速駆動歯車２９ａと入力軸２０の連結が解除されるとともに、第２シフティングキースプリング４９を介して左向きに押されるプルリング４７によりアウタリング４６が戻されて、アウタリング４６とミドルリング４５とインナリング４４の間の各コーン面とコーン穴による摩擦係合が解除される。   If the sleeve 42 that rotates together with the input shaft 20 is shifted to the right from the neutral position shown in the drawing by a shift fork (not shown) engaged with the annular groove 42b, the outer ring is provided via the first shifting key spring 48. 46 is pushed rightward, the outer ring 46, the middle ring 45, and the inner ring 44 are frictionally engaged by the cone surfaces and the cone holes, and the fifth speed drive gear 29a is synchronized with the input shaft 20, and then the fifth speed The external spline 43 of the drive gear 29a is engaged with the internal spline 42a of the sleeve 42, and the fifth speed drive gear 29a is connected to the input shaft 20 to form the fifth speed stage.

上述した実施形態による手動変速機の作動状態では、変速歯車２６ａ，２６ｂ、２７ａ，２７ｂ、２８ａ，２８ｂ等により撹拌されて飛散されたハウジング本体１０ａ内の潤滑油は、図示を省略した導入通路を介してハウジングカバー１０ｂの内面とフランジ部２３ａの間の空間Ｓに送り込まれ、筒部２３ｂから矢印ａに示すように中心孔２１内に放出される。中心孔２１内に挿入された潤滑油送入部材２３の筒部２３ｂの先端は環状凹部２２の軸線方向範囲よりも奥まで突出されており、筒部２３ｂから中心孔２１内に放出された潤滑油が環状凹部２２内に直接入ることはないので、中心孔２１の奥側に設けられた各分配孔２１ａ〜２１ｃには充分に潤滑油が分配される。   In the operating state of the manual transmission according to the above-described embodiment, the lubricating oil in the housing body 10a that has been agitated and scattered by the transmission gears 26a, 26b, 27a, 27b, 28a, 28b, etc. passes through the introduction passage (not shown). Then, it is fed into the space S between the inner surface of the housing cover 10b and the flange portion 23a, and discharged into the center hole 21 as shown by the arrow a from the cylindrical portion 23b. The tip of the cylindrical portion 23b of the lubricating oil feeding member 23 inserted into the center hole 21 protrudes farther than the axial range of the annular recess 22 and lubrication released into the central hole 21 from the cylindrical portion 23b. Since the oil does not directly enter the annular recess 22, the lubricating oil is sufficiently distributed to the distribution holes 21 a to 21 c provided on the back side of the center hole 21.

また、筒部２３ｂと中心孔２１の間を通って入力軸２０の一端面２０ｂ側に流れる潤滑油は、一端面２０ｂに形成された中心孔２１の後端の開口からハウジングカバー１０ｂ内に排出されようとするが、中心孔２１の後部の内面には相当な軸線方向範囲にわたり環状凹部２２が形成され、この環状凹部２２の底面は一端面２０ｂから離れるにつれて次第に径が増大するテーパ面状としたので、筒部２３ｂと中心孔２１の間を一端面２０ｂ側に流れる潤滑油は、入力軸２０の回転により生じる遠心力と環状凹部２２のテーパ面の作用により、矢印ｂに示すように入力軸２０の一端面２０ｂから離れる向きに戻されて一端面２０ｂからハウジング１０内に排出されようとする潤滑油が減少し、環状凹部２２内の潤滑油は環状凹部２２の底面の径が最大となる位置付近に形成された第４分配孔２１ｄ及びクラッチハブ４１に形成した連通孔４１ｂを介して第２変速クラッチ４０の各部に供給される。さらにハウジングカバー１０ｂ内で撹拌され飛散されて、矢印ｃに示すように、ハウジング１０の内面あるいはこれに取り付けられる潤滑油送入部材２３のフランジ部２３ａに沿って流れ落ちる潤滑油の一部も入力軸２０の一端面２０ｂに形成された開口からテーパ面に沿って環状凹部２２内に吸い込まれる。   Further, the lubricating oil that flows between the cylindrical portion 23b and the center hole 21 and flows toward the one end face 20b of the input shaft 20 is discharged into the housing cover 10b from the opening at the rear end of the center hole 21 formed in the one end face 20b. However, an annular recess 22 is formed on the inner surface of the rear portion of the center hole 21 over a considerable axial range, and the bottom surface of the annular recess 22 has a tapered surface shape whose diameter gradually increases as the distance from the one end surface 20b increases. As a result, the lubricating oil flowing toward the one end face 20b between the cylindrical portion 23b and the center hole 21 is input as shown by the arrow b due to the centrifugal force generated by the rotation of the input shaft 20 and the action of the tapered surface of the annular recess 22. The lubricating oil that is returned to the direction away from the one end surface 20b of the shaft 20 and is discharged from the one end surface 20b into the housing 10 decreases, and the lubricating oil in the annular recess 22 has a diameter of the bottom surface of the annular recess 22. Is supplied to each part of the second shift clutch 40 via the fourth distribution holes 21d and the communication hole 41b formed in the clutch hub 41 which is formed at a position nearby becomes large. Further, as indicated by an arrow c, a part of the lubricating oil that is stirred and scattered in the housing cover 10b and flows down along the flange portion 23a of the lubricating oil feeding member 23 attached to the housing 10 is also input shaft. 20 is sucked into the annular recess 22 from the opening formed in the one end surface 20b along the tapered surface.

上述したようにこの実施形態によれば、中心孔２１内に保持される潤滑油量が増大するので、入力軸２０の外周面２０ａに設けられる各駆動歯車２７ａ，２８ａ，２９ａの軸受部及び第２変速クラッチ４０の潤滑不足が生じ難くなる。なお、筒部２３ｂと中心孔２１の間の隙間を減少させなくても上記作用は行われ、従って中心孔２１の加工精度や潤滑油送入部材２３の加工精度及び取付精度を高める必要はないので、製造コストが増大することもない。   As described above, according to this embodiment, the amount of lubricating oil retained in the center hole 21 is increased, so that the bearing portions of the drive gears 27a, 28a, 29a provided on the outer peripheral surface 20a of the input shaft 20 and the first Insufficient lubrication of the two-speed clutch 40 is unlikely to occur. Even if the gap between the cylindrical portion 23b and the center hole 21 is not reduced, the above-described operation can be performed. Therefore, it is not necessary to increase the processing accuracy of the center hole 21, the processing accuracy and the mounting accuracy of the lubricating oil feeding member 23. Therefore, the manufacturing cost does not increase.

また上述した実施形態では、入力軸２０の一端面２０ｂと対向するハウジングカバー１０ｂの内面と、この内面に取り付けられる潤滑油送入部材２３のフランジ部２３ａとの間に空間Ｓを形成して、この空間Ｓにハウジング本体１０ａ内で撹拌され飛散される潤滑油が導入通路を介して送り込まれるようにしており、このようにすれば潤滑油を供給するポンプを設ける必要がないので回転軸に設けた部材への潤滑油供給装置の構造を簡略化して製造コストを少なくすることができる。しかしながら本発明はこれに限られるものではなく、潤滑油ポンプにより潤滑油送入部材２３に潤滑油を送り込むようにして実施することもできる。   In the above-described embodiment, the space S is formed between the inner surface of the housing cover 10b facing the one end surface 20b of the input shaft 20 and the flange portion 23a of the lubricating oil feeding member 23 attached to the inner surface. Lubricating oil that is stirred and scattered in the housing body 10a is fed into the space S through the introduction passage. In this way, there is no need to provide a pump for supplying the lubricating oil, so the rotating shaft is provided. The structure of the lubricating oil supply device for the remaining members can be simplified and the manufacturing cost can be reduced. However, the present invention is not limited to this, and the present invention can be carried out by feeding the lubricating oil into the lubricating oil feeding member 23 by a lubricating oil pump.

なお上述した実施形態では、本発明を自動車の手動変速機に適用した例につき説明したが、本発明は自動車の手動変速機に限られるものではなく、回転軸を備えたその他の機器に適用することも可能である。   In the above-described embodiment, the example in which the present invention is applied to a manual transmission of an automobile has been described. However, the present invention is not limited to the manual transmission of an automobile, and is applied to other devices having a rotating shaft. It is also possible.
