Description

本発明は、動力伝達機構や搬送機構などに用いられるチェーンに関し、特に、ブシュとピンとの間に供給する潤滑油をチェーン内に貯留させたチェーンに関する。   The present invention relates to a chain used for a power transmission mechanism, a conveyance mechanism, and the like, and more particularly to a chain in which lubricating oil supplied between a bush and a pin is stored in the chain.

従来から、動力伝達機構や搬送機構などに用いられ、チェーン内に潤滑油を保有させたチェーンとして、内プレートに嵌着されるブシュとして含油焼結ブシュを用い、含浸させた潤滑油をブシュとピンの間に供給するようにしたものや、内プレートと外プレートとの間にＯリングを配置してブシュとピンの間のシールを行い、封入されているグリース等の潤滑油の飛散防止と外部からの異物の侵入を防止するようにしたものがある。   Conventionally, oil-impregnated sintered bushes have been used as bushes that are used in power transmission mechanisms, transport mechanisms, etc., and in which the lubricating oil is retained in the chain, and the bushes that are fitted to the inner plate. What is supplied between the pins and an O-ring between the inner plate and the outer plate to seal between the bushing and the pin, and to prevent scattering of lubricating oil such as enclosed grease Some have been designed to prevent the entry of foreign objects from the outside.

また、内プレートと外プレートとの対向面の間に、ブシュとピンの間の潤滑油の漏出経路を塞ぐように、潤滑油を保持する吸湿材を配設し、吸湿材に含浸させた潤滑油をブシュとピンの間に供給するものもある（特許文献１参照）。
特開平１１−３５１３３８号公報 In addition, a hygroscopic material that retains the lubricating oil is disposed between the opposing surfaces of the inner plate and the outer plate so as to block the lubricating oil leakage path between the bush and the pin, and the lubricating material impregnated with the hygroscopic material. Some supply oil between bushes and pins (see Patent Document 1).

Since the lubricating oil which is easily deteriorated by heat and the filling amount is small, there is a problem that the oil-free life is short.

さらに、吸湿材を配設したチェーンでは、保油力の小さい羊毛や合成繊維製のフェルト、不織布又はスポンジを吸湿材として使用しているので、運転中の遠心力により保有されている潤滑油はチェーン外部に飛散して有効に活用できず、無給油寿命が短いという問題があった。   Furthermore, in a chain with a hygroscopic material, wool, synthetic fiber felt, non-woven fabric or sponge with low oil retention is used as the hygroscopic material, so the lubricating oil retained by the centrifugal force during operation is There was a problem that it was scattered outside the chain and could not be used effectively, and the oil-free life was short.

そこで、本発明は、前述したような従来技術の問題を解決するものであって、すなわち、本発明の目的は、ブシュとピンとの間に供給する潤滑油を外部へ飛散することなくチェーン内に大量に貯留させるとともに、貯留した潤滑油をブシュとピンとの間に確実に供給できるようし、さらに、ブシュとピンとの間に発生する摺動熱による潤滑油の劣化を抑制して、無給油寿命を向上させた無給油チェーンを提供することである。   Therefore, the present invention solves the problems of the prior art as described above, that is, the object of the present invention is to provide the lubricating oil supplied between the bush and the pin in the chain without splashing outside. A large amount of oil is stored and the stored lubricating oil can be reliably supplied between the bushing and the pin.

本実施例の貯油槽を備えたチェーン１００は、図１及び図２に示すように、一対の内プレート１１０、１１０のブシュ孔１１０ａに嵌着されたブシュ１２０，１２０と、このブシュ１２０，１２０を嵌挿して一対の外プレート１３０，１３０のピン孔１３０ａに嵌着されたピン１４０により、一対の内プレート１１０，１１０と一対の外プレート１３０，１３０とが交互に多数連結されている。
そして、ブシュ１２０とピン１４０との間に潤滑油を供給する貯油槽１５０、１５０が、内部を密閉してそれぞれの内プレート１１０、１１０に装着されており、貯油槽１５０と外プレート１３０との間には隙間が設けてある。
なお、符号１６０は、一対の内プレート間のブシュ１２０に外嵌したローラである。 As shown in FIGS. 1 and 2, the chain 100 including the oil storage tank according to the present embodiment includes bushes 120 and 120 fitted into the bush holes 110 a of the pair of inner plates 110 and 110, and the bushes 120 and 120. The pair of inner plates 110, 110 and the pair of outer plates 130, 130 are alternately connected in large numbers by pins 140 fitted in the pin holes 130 a of the pair of outer plates 130, 130.
Oil storage tanks 150 and 150 for supplying lubricating oil between the bushes 120 and the pins 140 are attached to the inner plates 110 and 110 with the inside sealed, and the oil storage tank 150 and the outer plate 130 are connected to each other. There is a gap between them.
Reference numeral 160 denotes a roller fitted around the bush 120 between the pair of inner plates.

この貯油槽１５０は、図２及び図３に示すように、側壁１５１と、側壁１５１の外周端から内プレート方向に延出した周壁１５２とからなるキャップ状部材であり、側壁１５１の左右中央にブシュ嵌挿孔１５１ａ，１５１ａが穿孔されている。   2 and 3, the oil storage tank 150 is a cap-shaped member including a side wall 151 and a peripheral wall 152 extending from the outer peripheral end of the side wall 151 toward the inner plate. Bush fitting insertion holes 151a and 151a are perforated.

また、ブシュ１２０は、貯油槽１５０が内プレート１１０の外側に装着された際に、その一部を貯油槽１５０内に配置するように内プレート１１０の外側面から延出しており、このブシュ１２０の延出部１２０ａには、貯油槽１５０内に開口して槽内の潤滑油をブシュ１２０とピン１４０との間に供給する給油口１２１が上下２つ設けられている。   The bush 120 extends from the outer surface of the inner plate 110 so that a part of the bush 120 is disposed in the oil storage tank 150 when the oil storage tank 150 is attached to the outer side of the inner plate 110. The extending portion 120 a is provided with two upper and lower oil supply ports 121 that open into the oil storage tank 150 and supply lubricating oil in the tank between the bush 120 and the pin 140.

さらに、側壁１５１内面には、油収集用ガイド部材１５３が設けられ、この油収集用ガイド部材１５３は、ブシュの延出部１２０ａ，１２０ａを取り巻くように、それぞれのブシュ嵌挿孔１５１ａ，１５１ａの外周端から周壁１５２の内面に向けて渦巻き状で、点対称に配置されている。
このように、点対称に配置すると、貯油槽１５０を、上下左右ランダムに内プレート１１０及びブシュの延出部１２０ａに装着できるので組立が容易である。 Furthermore, an oil collecting guide member 153 is provided on the inner surface of the side wall 151, and the oil collecting guide member 153 is formed in each bush fitting insertion hole 151a, 151a so as to surround the bush extending portions 120a, 120a. They are spirally arranged from the outer peripheral end toward the inner surface of the peripheral wall 152 and are arranged point-symmetrically.
If the oil storage tank 150 is arranged point-symmetrically in this way, the assembly can be easily performed because the oil storage tank 150 can be mounted on the inner plate 110 and the bush extension 120a at random in the vertical and horizontal directions.

そして、内部にグリース等の潤滑油を充填して、側壁１５１を、ブシュ嵌挿孔１５１ａ，１５１ａを介して、内プレート１１０の外側のブシュの延出部１２０ａに、延出部１２０ａの先端が側壁１５１の外側面から突出するように嵌挿し、周壁１５２を内プレート１１０の外周面１１０ａに圧入被嵌することによって、内部を密閉した貯油槽１５０が形成されるとともに、ブシュ１２０の延出部１２０ａ、すなわち、ブシュ１２０の一部を貯油槽１５０の内部に配置して内プレート１１０に装着されている。   Then, lubricating oil such as grease is filled inside, and the distal end of the extended portion 120a is connected to the extended portion 120a of the bush on the outer side of the inner plate 110 through the bush fitting insertion holes 151a and 151a. The oil storage tank 150 is formed so that the inner wall 110 is sealed by inserting the peripheral wall 152 into the outer peripheral surface 110a of the inner plate 110 by being inserted so as to protrude from the outer surface of the side wall 151, and the extending portion of the bush 120 120 a, that is, a part of the bush 120 is disposed inside the oil storage tank 150 and attached to the inner plate 110.

このように、周壁１５２を圧入すると、周壁１５２の内周面と内プレート１１０の外周面との間の密閉されて槽内の潤滑油の漏出が防止できる。
また、周壁１５２と内プレート１１０の外周面との間を接着剤により密閉して潤滑油の漏出を防止するようにしても良く、さらに、楕円形状の内プレートを用い、その外周面に断面Ｖ字状の溝を周設して、このＶ字状の溝にＯリング等のシール部材を配置して、周壁内周面と内プレート外周面の間の密閉性を高めても良い。 In this way, when the peripheral wall 152 is press-fitted, the space between the inner peripheral surface of the peripheral wall 152 and the outer peripheral surface of the inner plate 110 is sealed, and leakage of lubricating oil in the tank can be prevented.
Further, the gap between the peripheral wall 152 and the outer peripheral surface of the inner plate 110 may be sealed with an adhesive to prevent leakage of the lubricating oil. Furthermore, an elliptical inner plate is used and the outer peripheral surface has a cross-section V. A sealing member such as an O-ring may be arranged around the V-shaped groove and an O-ring or the like may be disposed in the V-shaped groove to improve the sealing performance between the inner peripheral surface of the peripheral wall and the outer peripheral surface of the inner plate.

本実施例の貯油槽を備えたチェーン１００は、前述したような構成であるので、チェーン運転中に、ブシュ１２０とピン１４０の間の潤滑油が消耗されても、貯油槽１５０内の潤滑油が給油口１２１を介してブシュ１２０とピン１４０の間に補給され、しかも、貯油槽１５０内の潤滑油は、油収集ガイド部材１５３により強制的に給油口に導かれて、潤滑油を余すことなく供給されるので、長期にわたる無給油運転を実現できる。
また、貯油槽１５０の外側面と外プレート１３０との間には、ブシュ１２０の先端が突出しているので、内プレート１３０がチェーン進行方向と直交する方向に動いても隙間が確実に確保され、この隙間を通過する運転中の気流により貯油槽１５０が冷却されるので貯油槽１５０及びブシュ１２０とピン１４０との間の潤滑油の過熱による劣化を抑制することができる。
しかも、確保された隙間によって、内プレート１１０が外プレート１３０方向に動いても、貯油槽１５０は外プレートに接触しないので、貯油槽１５０の損傷を防止することができる。 Since the chain 100 having the oil storage tank of the present embodiment has the above-described configuration, even if the lubricating oil between the bush 120 and the pin 140 is consumed during the chain operation, the lubricating oil in the oil storage tank 150 is consumed. Is supplied between the bush 120 and the pin 140 through the oil supply port 121, and the lubricating oil in the oil storage tank 150 is forcibly guided to the oil supply port by the oil collecting guide member 153 to leave the lubricating oil. Since it is supplied without any problems, it is possible to realize long-term oil-free operation.
Further, since the tip of the bush 120 protrudes between the outer surface of the oil storage tank 150 and the outer plate 130, a gap is reliably ensured even if the inner plate 130 moves in a direction perpendicular to the chain traveling direction, Since the oil storage tank 150 is cooled by the airflow during operation that passes through the gap, deterioration due to overheating of the lubricating oil between the oil storage tank 150 and the bush 120 and the pin 140 can be suppressed.
Moreover, even if the inner plate 110 moves in the direction of the outer plate 130 due to the secured gap, the oil storage tank 150 does not contact the outer plate, so that the oil storage tank 150 can be prevented from being damaged.

なお、貯油槽１５０の側壁１５１に設ける油収集ガイド部材１５３は、図４に示すような、仕切板１５３ａにより槽内を区画し、それぞれの区画室に渦巻き状の油収集ガイド部材１５３を配置したものでも良く、図５に示すような、湾曲したガイド板１５３ｂを嵌挿されたブシュの延出部１２０ａの外周に沿って放射状に複数設けて油収集ガイド部材１５３を構成しても良く、図６に示すような、湾曲したガイド板１５３ｃを嵌挿されたブシュ１２０の延出部１２０ａの外周に沿って放射状に複数設けるとともに、これらガイド板１５３ｃの間に、ブシュ１２０の延出部１２０ａの外周から間隔をおいて複数の湾曲したガイド板１５３ｄを配置して油収集ガイド部材１５３を構成しても良い。
また、これらの油収集ガイド部材１５３，１５３は、点対称に配置されている。 The oil collecting guide member 153 provided on the side wall 151 of the oil storage tank 150 is partitioned by a partition plate 153a as shown in FIG. 4, and a spiral oil collecting guide member 153 is disposed in each partition chamber. As shown in FIG. 5, the oil collecting guide member 153 may be configured by providing a plurality of radial shapes along the outer periphery of the extended portion 120a of the bush into which the curved guide plate 153b is inserted, as shown in FIG. As shown in FIG. 6, a plurality of radial guide plates 153 c are radially provided along the outer periphery of the extended portion 120 a of the bush 120 into which the curved guide plate 153 c is inserted, and the extended portion 120 a of the bush 120 is interposed between the guide plates 153 c. The oil collecting guide member 153 may be configured by arranging a plurality of curved guide plates 153d at intervals from the outer periphery.
Further, these oil collecting guide members 153 and 153 are arranged point-symmetrically.

次に、本発明の第２実施例である貯油槽を備えたチェーン２００について、図７及び図８により説明する。
ここで、図７は、チェーン長手方向と直交する方向からみた本実施例の貯油槽を備えたチェーンの断面図であり、図８は、本実施例のブッシュの斜視図である。 Next, a chain 200 having an oil storage tank according to a second embodiment of the present invention will be described with reference to FIGS.
Here, FIG. 7 is a cross-sectional view of the chain provided with the oil storage tank of the present embodiment viewed from a direction orthogonal to the longitudinal direction of the chain, and FIG. 8 is a perspective view of the bush of the present embodiment.

本実施例の貯油槽を備えたチェーン２００は、前述した貯油槽を備えたチェーン１００と対比すると、貯油槽２５０の装着形態とブシュの延出部に設けた給油口のみが異なっており、その他の具体的な構成は、前述した貯油槽を備えたチェーン１００と同じであるから、貯油槽を備えたチェーン１００と同一の部材に対応する２００番台の符号を付して重複する説明は省略する。   The chain 200 provided with the oil storage tank of the present embodiment is different from the chain 100 provided with the oil storage tank described above only in the mounting form of the oil storage tank 250 and the oil supply port provided in the extension part of the bush. The specific configuration is the same as that of the chain 100 provided with the oil storage tank described above, and therefore, the same reference numerals as those in the 200th series corresponding to the same members as those of the chain 100 provided with the oil storage tank are used and redundant description is omitted. .

そこで、貯油槽２５０は、図７に示すように、第１実施例と同様に、側壁２５１と、側壁２５１の外周端から内プレート方向に延出した周壁２５２とからなるキャップ状部材であり、ブシュ２２０は、その一部を貯油槽２５０内に配置するように、内プレート２１０の外側面から延出している。
そして、ブシュ２２０の延出部２２０ａの端面２２０ｂが側壁２５１の内側面に当接するように、側壁２５１がピン２４０に嵌挿され、周壁２５２を内プレート２１０の外周面に圧入被嵌することによって、内部が密閉した貯油槽２５０が形成されるとともに、ブシュ２２０の延出部２２０ａ、すなわち、ブシュ２２０の一部が貯油槽２５０の内部に配置されて内プレート２１０の外側に装着されている。
なお、本実施例も、第１実施例と同様に、貯油槽２５０内に油収集ガイド部材２５３が設けられている。この油収集ガイド部材２５３の機能は第１実施例と同様であるので説明は省略する。 Therefore, as shown in FIG. 7, the oil storage tank 250 is a cap-like member including a side wall 251 and a peripheral wall 252 extending in the inner plate direction from the outer peripheral end of the side wall 251, as in the first embodiment. The bush 220 extends from the outer surface of the inner plate 210 so that a part of the bush 220 is disposed in the oil storage tank 250.
Then, the side wall 251 is fitted into the pin 240 so that the end surface 220b of the extended portion 220a of the bush 220 abuts on the inner side surface of the side wall 251, and the peripheral wall 252 is press-fitted to the outer peripheral surface of the inner plate 210. In addition, an oil storage tank 250 whose inside is sealed is formed, and an extended portion 220a of the bush 220, that is, a part of the bush 220 is disposed inside the oil storage tank 250 and attached to the outside of the inner plate 210.
In this embodiment, an oil collecting guide member 253 is provided in the oil storage tank 250 as in the first embodiment. Since the function of the oil collecting guide member 253 is the same as that of the first embodiment, description thereof is omitted.

また、本実施例のブシュ２２０は、図８に示すように、端面２２０ｂに、両端が開放されて半径方向に延びる溝２２２が放射状に複数形成されているので、側壁２５１の内側面に当接したブシュの端面２２０ｂに備えられた溝２２２によって、ブッシュの延出部２２０ａに、貯油槽２５０内の潤滑油をブシュ２２０とピン２４０の間に供給する給油口２２１が形成される。   Further, as shown in FIG. 8, the bush 220 of this embodiment has a plurality of radially extending grooves 222 that are open at both ends and radially formed on the end surface 220 b, so that it abuts against the inner surface of the side wall 251. By the groove 222 provided in the end face 220b of the bush, an oil supply port 221 for supplying the lubricating oil in the oil storage tank 250 between the bush 220 and the pin 240 is formed in the extending portion 220a of the bush.

このように、加工のし易い端部２２０ｂに溝２２２を設けることで、給油口が形成されるので、給油口２２１の形成が容易である。   In this manner, the oil supply port is formed by providing the groove 222 in the end portion 220b that is easy to process, and therefore the formation of the oil supply port 221 is easy.

次に、本発明の第３実施例である貯油槽を備えたチェーン３００について、図９及び図１０により説明する。
ここで、図９は、本実施例の貯油槽を備えたチェーンの組立図であり、図１０は、チェーン長手方向と直交する方向からみた本実施例の貯油槽を備えたチェーン断面図である。 Next, a chain 300 having an oil storage tank according to a third embodiment of the present invention will be described with reference to FIGS.
Here, FIG. 9 is an assembly view of a chain provided with the oil storage tank of the present embodiment, and FIG. 10 is a cross-sectional view of the chain provided with the oil storage tank of the present embodiment viewed from a direction orthogonal to the chain longitudinal direction. .

本実施例の貯油槽を備えたチェーン３００は、前述した貯油槽を備えたチェーン１００と対比すると、貯油槽３５０の形態のみが異なっており、その他の具体的な構成は、前述した貯油槽を備えたチェーン１００と同じであるから、貯油槽を備えたチェーン１００と同一の部材に対応する３００番台の符号を付して重複する説明は省略する。   The chain 300 provided with the oil storage tank of this embodiment is different from the chain 100 provided with the oil storage tank described above only in the form of the oil storage tank 350, and other specific configurations are the same as those of the oil storage tank described above. Since it is the same as the provided chain 100, the same reference numerals as those in the 300th series corresponding to the same members as those of the chain 100 provided with the oil storage tank are used, and redundant description is omitted.

そこで、貯油槽３５０は、図９及び図１０に示すように、油留め板３５１とブシュの延出部３２０ａを囲むように、油留まり板３５１の内側面と内プレート３１０の外側面との間に配置されたＯリング３５２のようなシール部材とから構成され、内プレート３１０のブシュ孔３１０ａに嵌着されたブシュ３２０は、その一部を貯油槽３５０内に配置するように、内プレート３１０の外側面から延出している。
そして、油留め板３５１には、左右中央にブシュ嵌挿孔３５１ａ，３５１ａが穿孔され、このブシュ嵌挿孔３５１ａ，３５１ａを囲むようにＯリング３５２，３５２を配置して、グリース等の潤滑油をＯリング内に充填した後、油留め板３５１をブシュ嵌挿孔３５１ａ，３５１ａを介してブシュの延出部３２０ａ嵌挿することによって、内部が密閉された貯油槽３５０が形成されるとともに、ブシュ３２０の延出部３２０ａ、すなわち、ブシュ３２０の一部が貯油槽３５０の内部に配置されて内プレート３１０の外側に装着されている。
なお、本実施例でも、第１実施例と同様に、ブシュの延出部３２０ａの先端は、油留め板３５１の外側に突出している。 Therefore, as shown in FIGS. 9 and 10, the oil storage tank 350 is provided between the inner surface of the oil retaining plate 351 and the outer surface of the inner plate 310 so as to surround the oil retaining plate 351 and the bush extension portion 320a. The bush 320, which is composed of a seal member such as an O-ring 352 disposed in the inner plate 310 and is fitted in the bush hole 310a of the inner plate 310, is disposed in the oil storage tank 350 so that a part thereof is disposed in the oil storage tank 350. It extends from the outer surface of the.
The oil retaining plate 351 is provided with bushing insertion holes 351a and 351a in the center of the left and right sides, and O-rings 352 and 352 are disposed so as to surround the bushing insertion holes 351a and 351a. After filling the O-ring into the oil retaining plate 350, the bushing extension hole 320a is inserted into the bushing insertion hole 351a through the bushing insertion hole 351a. An extension part 320 a of the bush 320, that is, a part of the bush 320 is disposed inside the oil storage tank 350 and attached to the outside of the inner plate 310.
In this embodiment as well, as in the first embodiment, the tip of the bushing extension 320 a protrudes outside the oil retaining plate 351.

また、油留め板３５１の内側面には、油収集ガイド部材３５３が、ブシュの延出部３２０ａを取り巻くように、Ｏリング３５２とブシュ嵌挿孔３５１ａとの間に渦巻き状に配置されている。
なお、この油収集ガイド部材３５３の機能は、前記した第１実施例の油収集ガイド部材１５３と同じであるから、その説明は省略する。 Further, on the inner side surface of the oil retaining plate 351, an oil collecting guide member 353 is disposed in a spiral shape between the O-ring 352 and the bushing insertion hole 351a so as to surround the bush extension portion 320a. .
Since the function of the oil collecting guide member 353 is the same as that of the oil collecting guide member 153 of the first embodiment, the description thereof is omitted.

次に、本発明の第４実施例である貯油槽を備えたチェーン４００について、図１１乃至図１６により説明する。
ここで、図１１は、チェーン長手方向と直交する方向からみた第４実施例の貯油槽を備えたチェーンの断面図であり、図１２は、油溜まり用凹部を設けた捲きブシュの説明図であり、図１３は、油溜まり用凹部の別の態様を示した斜視図であり、図１４は、発泡金属を充填した油溜まり用凹部の斜視図であり、図１５は、発泡金属を充填した油溜まり用凹部の第２の態様を示した斜視図であり、図１６は、発泡金属を充填した油溜まり用凹部の第３の態様を示した斜視図である。 Next, a chain 400 having an oil storage tank according to a fourth embodiment of the present invention will be described with reference to FIGS.
Here, FIG. 11 is a cross-sectional view of the chain provided with the oil storage tank of the fourth embodiment as seen from the direction orthogonal to the longitudinal direction of the chain, and FIG. 12 is an explanatory view of a fired bush provided with an oil reservoir recess.

It is the perspective view which showed the 2nd aspect of the recessed part for oil reservoirs, and FIG. 16 is the perspective view which showed the 3rd aspect of the recessed part for oil reservoirs filled with the foam metal.

本実施例の貯油槽を備えたチェーン４００は、前述した貯油槽を備えたチェーン１００と対比すると、ブシュ４２０の形態のみが異なっており、その他の具体的な構成は、前述した貯油槽を備えたチェーン１００と同じであるから、貯油槽を備えたチェーン１００と同一の部材に対応する４００番台の符号を付して重複する説明は省略する。   The chain 400 provided with the oil storage tank of this embodiment is different from the chain 100 provided with the oil storage tank described above only in the form of the bush 420, and other specific configurations include the oil storage tank described above. Since the chain 100 is the same as the chain 100, the same reference numerals as those in the 400th series corresponding to the same members as those of the chain 100 having the oil storage tank are used, and redundant description is omitted.

そこで、前記ブシュ４２０は、図１１に示すように、内プレート４１０の外側から延出した延出部４２０ａに、貯油槽４５０内の潤滑油をブシュ４２０とピン４４０との間に供給する給油口４２１と、この給油口４２１に連通してブシュ４２０の長手方向に延びる油溜まり用凹部４２２が設けられている。   Therefore, as shown in FIG. 11, the bush 420 supplies the lubricating oil in the oil storage tank 450 between the bush 420 and the pin 440 to the extending portion 420 a extending from the outside of the inner plate 410. 421 and an oil reservoir recess 422 that extends in the longitudinal direction of the bush 420 in communication with the oil supply port 421 are provided.

そして、第１実施例と同様に、側壁４５１と周壁４５２とからなるキャップ状の貯油槽４５０を、ブッシュ４２０の延出部４２０ａに側壁４５１を嵌挿するとともに、周壁４５２を内プレート４１０の外周面に被嵌して内プレート４１０の外側に装着されている。   As in the first embodiment, the cap-shaped oil storage tank 450 including the side wall 451 and the peripheral wall 452 is inserted into the extending portion 420 a of the bush 420 and the side wall 451 is inserted into the outer periphery of the inner plate 410. It is fitted on the surface and attached to the outside of the inner plate 410.

このブシュ４２０は、矩形の金属板Ｐを円筒状に成形した巻きブシュであり、図１２（ａ）に示すように、矩形の金属板Ｐの両端面Ｐ１，Ｐ１に、傾斜面４２２ａ，４２２ａを両側及び下部を残して形成し、この傾斜面４２０ａの両側に断面半円状の凹部４２１ａ，４２１ａを形成して、この金属板Ｐを、図１２（ｂ）に示すように、円筒状に形成して両端面Ｐ１，Ｐ１を突き合わせることによって、対向する断面半円状の凹部４２１ａ，４２１ａにより給油口４２１が形成されるとともに、この給油口４２１に連通し、両端が閉鎖された断面Ｖ字状の油溜まり部４２２が対向する傾斜面４２２ａ，４２２ａにより形成されている。   The bush 420 is a wound bush formed by forming a rectangular metal plate P into a cylindrical shape. As shown in FIG. 12A, inclined surfaces 422a and 422a are provided on both end faces P1 and P1 of the rectangular metal plate P. The metal plate P is formed in a cylindrical shape as shown in FIG. 12 (b) by forming the concave portions 421a and 421a having a semicircular cross section on both sides of the inclined surface 420a. Then, by abutting the both end faces P1 and P1, a refueling port 421 is formed by the concave portions 421a and 421a having a semicircular cross section facing each other, and a V-shaped cross section that is communicated with the refueling port 421 and closed at both ends. An oil reservoir 422 is formed by inclined surfaces 422a and 422a facing each other.

したがって、給油口４２１から流入した潤滑油は、ブシュ４２０の長手方向に流動するとともに表面張力により油溜まり用凹部４２２内に保持され、ブシュ４２０とピン４４０の間の長手方向に供給されるので、局部的な潤滑油欠乏による偏摩耗が防止できる。   Accordingly, the lubricating oil flowing in from the oil supply port 421 flows in the longitudinal direction of the bush 420 and is held in the oil reservoir recess 422 by the surface tension and is supplied in the longitudinal direction between the bush 420 and the pin 440. Uneven wear due to local lack of lubricating oil can be prevented.

また、溜まり用凹部４２２の別の態様としては、図１３（ａ）に示すように、金属板Ｐの両端面Ｐ１、Ｐ１に、両端が閉鎖された断面半円形の溝４２２ｂ，４２２ｂと、この溝４２２ｂ，４２２ｂの両側に外面に開口する断面半円状の凹部４２１ａ，４２１ａと、内面に開口する複数の断面半円状の凹部４２３ａ，４２３ａを形成し、両端面Ｐ１，Ｐ１を突き合わせることによって、図１３（ｂ）に示すように、給油口４２１と、この給油口４２１に連通して両端が閉鎖された断面円形の中空状の油溜まり用凹部４２２及び流出口４２３が形成されている。
そして、給油口４２１から流入した潤滑油は、この中空状の溜まり用凹部４２２に保持されて流出孔４２３を介してブシュ４２０とピン４４０との間の長手方向に供給される。 Further, as another aspect of the recess 422 for accumulation, as shown in FIG. 13 (a), grooves 422b and 422b having semicircular cross sections whose both ends are closed on both end faces P1 and P1 of the metal plate P, Recesses 421a, 421a having a semicircular cross section that opens to the outer surface and grooves 423a, 423a having a semicircular cross section that opens to the inner surface are formed on both sides of the grooves 422b, 422b, and both end faces P1, P1 are abutted. Thus, as shown in FIG. 13B, there are formed an oil supply port 421, a hollow oil sump recess 422 having a circular cross-section that communicates with the oil supply port 421 and is closed at both ends, and an outlet 423. .
The lubricating oil flowing in from the oil supply port 421 is held in the hollow reservoir recess 422 and supplied in the longitudinal direction between the bush 420 and the pin 440 through the outflow hole 423.

さらに、油溜まり用凹部４２２に、保油機能を向上させるように、発泡金属Ｍを充填することもできる。
発泡金属Ｍは、高い空隙率と大きな変形性を有するため、保油能力が優れるとともに、油溜まり用凹部への充填が容易であり、この発泡金属Ｍによる保油機能により、ブシュとピンの間に潤滑油を過不足無く供給することができる。このように発泡金属Ｍを充填すると、ブシュ端面からの潤滑油の漏出を抑制できるので、油溜まり用凹部４２２の両端を開放してもよい。 Further, the foamed metal M can be filled in the oil reservoir recess 422 so as to improve the oil retaining function.
Since the metal foam M has a high porosity and large deformability, it has excellent oil retaining ability and can be easily filled into the oil reservoir recess. The oil retaining function of the metal foam M allows the gap between the bush and the pin. It is possible to supply lubricating oil without excess or deficiency. When the foam metal M is filled in this manner, leakage of the lubricating oil from the bushing end surface can be suppressed, so that both ends of the oil reservoir recess 422 may be opened.

図１４乃至図１６は、発泡金属Ｍを充填した油溜まり用凹部４２２の形態を示したもので、図１４（ａ）に示すように、金属板Ｐの両端面Ｐ１，Ｐ１に傾斜面４２２ｃ，４２２ｃと、この傾斜面４２２ｃの両側に断面半円状の凹部４２１ａ，４２１ａを形成し、この端面Ｐ１，Ｐ１を突き合わせて、図１４（ｂ）に示すように、給油口４２１と両端が開放され、ブシュ４２０の内周面に開口した断面Ｖ字状の油溜まり用凹部４２２が形成され、この油溜まり用凹部４２２に発泡金属Ｍが充填されている。   FIGS. 14 to 16 show the form of the oil sump recess 422 filled with the foam metal M. As shown in FIG. 14A, the both end faces P1, P1 of the metal plate P are inclined surfaces 422c, 422c and concave portions 421a and 421a having a semicircular cross section are formed on both sides of the inclined surface 422c, and the end surfaces P1 and P1 are abutted to open the oil supply port 421 and both ends as shown in FIG. An oil reservoir recess 422 having a V-shaped cross-section opened on the inner peripheral surface of the bush 420 is formed, and the oil reservoir recess 422 is filled with a foam metal M.

The hollow oil reservoir recess 422 is formed inside the bush 430, and the oil reservoir recess 422 is filled with the foam metal M.
The oil reservoir recess 422 is provided with a slit 424 for supplying the lubricating oil in the oil reservoir recess 422 between the bush 420 and the pin 440.

さらに、油溜まり用凹部４２２の第３の形態として、図１６（ａ）に示すように、金属板Ｐの両端面Ｐ１，Ｐ１に、端面Ｐ１に開口した断面三角形状の溝４２２ｅ、４２２ｅと、この溝４２２ｅの両側に断面半円状の凹部４２１ａ，４２１ａを形成し、この端面Ｐ１，Ｐ１を突き合わせて、図１６（ｂ）に示すように、給油口４２１と両端が開放された断面四角形の中空状の油溜まり用凹部４２２をブシュ４２０の内部に形成し、この油溜まり用凹部４２２に発泡金属Ｍを充填しても良い。
なお、この油溜まり用凹部４２２には、図１５に示した油溜まり用凹部４２２と同様にスリット４２４が設けられている。
このようにブシュ４２０の内部に中空状の油溜まり用凹部を形成すると、発泡金属Ｍを確実に保持できる。 Further, as a third form of the oil reservoir recess 422, as shown in FIG. 16 (a), on both end faces P1, P1 of the metal plate P, grooves 422e, 422e having a triangular cross section opened to the end face P1, and Recesses 421a and 421a having a semicircular cross section are formed on both sides of the groove 422e, the end faces P1 and P1 are abutted to each other, and as shown in FIG.
