Description
【０００１】[0001]
本考案は、相対運動する二部材間を区分するのに用いられるオイルシールに関 する。 The present invention relates to an oil seal used for partitioning between two members that move relative to each other.
【０００２】[0002]
従来のオイルシールとしては、例えば図３(a) に示すように、相対運動自在に 配置された一方の部材としてのハウジング１０２と他方の部材としてのシャフト １０４との間を区分すべく、ハウジング１０２に固定されるシール本体１０３と 、シャフト１０４に嵌合部１１４が嵌合することで固定されるスリーブ１０５と が接触し、シャフト１０４に圧接する金属製の圧接部１１２をスリーブ１０５の 嵌合部１１４が有して成るものが知られている。 As a conventional oil seal, for example, as shown in FIG. 3 (a), the housing 102 is provided so as to be divided between a housing 102 as one member and a shaft 104 as the other member which are arranged so as to be relatively movable. The seal body 103 fixed to the shaft 104 and the sleeve 105 fixed by fitting the fitting part 114 to the shaft 104 come into contact with each other, and the metal pressure contact part 112 press-contacting the shaft 104 is connected to the fitting part of the sleeve 105. What 114 comprises is known.
【０００３】 上記した従来のオイルシール１０１にあっては、シャフト１０４に圧接する圧 接部１１２が金属製であるため伝導性が良く、スリーブ１０５とシール本体１０ ３のリップ部１０６との摺動発熱を放熱する効果はある。しかしながら、圧接部 １１２が剛な材質である金属より成るためスリーブ１０５をシャフト１０４に嵌 合するには大きな荷重を必要とし、装着性が悪いという欠点を有していた。In the above-described conventional oil seal 101, since the pressure contact portion 112 that pressure contacts the shaft 104 is made of metal, the conductivity is good, and the sliding between the sleeve 105 and the lip portion 106 of the seal body 103. It has the effect of releasing heat. However, since the press contact portion 112 is made of a metal, which is a rigid material, a large load is required to fit the sleeve 105 onto the shaft 104, and there is a drawback that the mountability is poor.
【０００４】 そこで、図３(b) に示すように、シャフト１０４に圧接する嵌合部１１４の圧 接部１１２をゴム製にしたものが考えられている。Therefore, as shown in FIG. 3 (b), it is considered that the press-contact portion 112 of the fitting portion 114 press-contacted to the shaft 104 is made of rubber.
【０００５】 圧接部１１２をゴム製にすることで、スリーブ１０５をシャフト１０４に嵌合 するのに要する荷重は小さくて済み、装着性は良くなる。By making the press contact portion 112 made of rubber, the load required for fitting the sleeve 105 to the shaft 104 can be small and the mountability can be improved.
【０００６】[0006]
しかしながら、圧接部１１２をゴム製にすると、圧接部１１２の伝導性が悪く なるので、スリーブ１０５とシール本体１０３のリップ部１０６との摺動発熱を 放熱する効果が低くなってしまう。 However, if the pressure contact portion 112 is made of rubber, the conductivity of the pressure contact portion 112 deteriorates, so that the effect of radiating the sliding heat generated between the sleeve 105 and the lip portion 106 of the seal body 103 is reduced.
【０００７】 本考案は上記した従来技術のもつ課題を解決するためになされたもので、その 目的とするところは、スリーブを他方の部材に装着する際の装着性が良く、なお かつスリーブとシール本体との摺動発熱を良好に放熱しうるオイルシールを提供 することにある。The present invention has been made in order to solve the above-mentioned problems of the prior art. The purpose of the present invention is to have a good mountability when the sleeve is mounted on the other member, and the sleeve and the seal. An object of the present invention is to provide an oil seal that can radiate heat generated by sliding with the main body.
【０００８】[0008]
上記課題を解決するために本考案にあっては、相対運動自在に配置された二部 材の間を区分すべく、一方の部材に固定されるシール本体と、他方の部材に嵌合 部が嵌合することで固定されるスリーブとが接触して成るオイルシールにおいて 、前記スリーブの嵌合部が、前記他方の部材に圧接する弾性部材製の圧接部と、 前記他方の部材に当接する良伝導性部材製の当接部と、から成ることを特徴とす る。 In order to solve the above-mentioned problems, in the present invention, a seal body fixed to one member and a fitting portion to the other member are provided in order to distinguish between two members arranged so as to be relatively movable. In an oil seal that is brought into contact with a sleeve that is fixed by fitting, the fitting portion of the sleeve is a resilient pressure member that is in pressure contact with the other member, and a good contact with the other member. And a contact portion made of a conductive member.
【０００９】[0009]
上記構成のオイルシールにあっては、スリーブはその嵌合部を他方の部材に嵌 合させることで、他方の部材に装着される。その際、嵌合部の圧接部は他方の部 材に圧接し、嵌合部の当接部は他方の部材に当接する。 In the oil seal configured as described above, the sleeve is attached to the other member by fitting the fitting portion of the sleeve to the other member. At that time, the press-contacting portion of the fitting portion presses against the other member, and the contact portion of the fitting portion contacts the other member.
【００１０】 そして、嵌合部の圧接部は弾性部材製であるため、他の部材への圧入に要する 荷重は、圧接部が剛な部材より成る場合に比べて小さくて済み、装着性が良い。 しかも、嵌合部の当接部は良伝導性部材製であるため、スリーブとシール本体と の摺動発熱が良好に他方の部材へと伝えられて、高い放熱効果が得られる。Since the press-contacting portion of the fitting portion is made of an elastic member, the load required for press-fitting into another member can be smaller than that in the case where the press-contacting portion is made of a rigid member, and the mountability is good. .. Moreover, since the abutting portion of the fitting portion is made of a material having good conductivity, sliding heat generated between the sleeve and the seal body is satisfactorily transmitted to the other member, and a high heat radiation effect can be obtained.
【００１１】[0011]
以下に本考案に係るオイルシールを図示の実施例に基づいて説明する。 An oil seal according to the present invention will be described below based on the illustrated embodiment.
【００１２】 図１(a) は本考案の第一の実施例に係るオイルシールを示し、同オイルシール １は、一方の部材としてのハウジング２に固定されるシール本体３と、他方の部 材としてのシャフト４に固定されるスリーブ５とが接触して成っている。FIG. 1A shows an oil seal according to a first embodiment of the present invention. The oil seal 1 includes a seal body 3 fixed to a housing 2 as one member and another member. And a sleeve 5 fixed to the shaft 4 as a contact.
【００１３】 ここで、ハウジング２とシャフト４とは相対運動自在に配置されており、ハウ ジング２とシャフト４との間は、前記オイルシール１により、二つの領域に区分 されている。Here, the housing 2 and the shaft 4 are arranged so as to be relatively movable, and the housing 2 and the shaft 4 are divided into two regions by the oil seal 1.
【００１４】 それから、シール本体３がスリーブ５と接触する箇所は、スリーブ５側へ向け て突出し、リップ部６を形成している。Then, a portion where the seal body 3 comes into contact with the sleeve 5 projects toward the sleeve 5 side to form a lip portion 6.
【００１５】 スリーブ５は、シール本体３のリップ部６と摺接する、金属等の材質より成る スリーブ環７と、このスリーブ環７の軸方向一側の内周面からスリーブ環７のフ ランジ部８に渡って固着されたカバー９と、スリーブ環７の軸方向他側の内周面 にスリーブ環７の返り１０とカバー９の端部とで挾んで取付けられたリング１１ とから構成される。The sleeve 5 is made of a material such as metal, which is in sliding contact with the lip portion 6 of the seal body 3, and the flange portion of the sleeve ring 7 from the inner peripheral surface of the sleeve ring 7 on one axial side. 8, a cover 9 fixedly attached to the sleeve ring 7, and a ring 11 mounted on the inner peripheral surface of the sleeve ring 7 on the other side in the axial direction with the barb 10 of the sleeve ring 7 and the end of the cover 9 sandwiched therebetween. ..
【００１６】 カバー９はゴム等の弾性部材製で、その内周部はシャフト４へのスリーブ５装 着時に、シャフト４と圧接し、圧接部１２を成す。The cover 9 is made of an elastic member such as rubber, and the inner peripheral portion thereof makes pressure contact with the shaft 4 when the sleeve 5 is attached to the shaft 4 to form a pressure contact portion 12.
【００１７】 リング１１は、アルミニウムなどの金属等より成る良伝導性部材製で、その内 周部は、シャフト４へのスリーブ５装着時に、シャフト４と圧のかからない状態 で当接し、当接部１３を成す。The ring 11 is made of a good conductive material such as a metal such as aluminum, and its inner peripheral portion abuts the shaft 4 when the sleeve 5 is mounted on the shaft 4 in a pressure-free state. Make thirteen.
【００１８】 ここで、圧接部１２と当接部１３は嵌合部１４を構成する。Here, the press contact portion 12 and the contact portion 13 form a fitting portion 14.
【００１９】 そして、本実施例においては、カバー９を加硫成形する際にスリーブ環８及び リング１１を一体で成型して、スリーブ５を構成している。In this embodiment, when the cover 9 is vulcanized, the sleeve ring 8 and the ring 11 are integrally molded to form the sleeve 5.
【００２０】 上記構成の本実施例の作用・効果を次に説明する。スリーブ５は、その嵌合部 １４をシャフト４に嵌合させることで、シャフト４に装着される。その際、嵌合 部１４の圧接部１２はシャフト４に圧接し、嵌合部１４の当接部１３はシャフト ４に圧のかからない状態で当接する。The operation and effect of this embodiment having the above configuration will be described below. The sleeve 5 is attached to the shaft 4 by fitting the fitting portion 14 into the shaft 4. At this time, the pressure contact portion 12 of the fitting portion 14 is in pressure contact with the shaft 4, and the contact portion 13 of the fitting portion 14 is in contact with the shaft 4 without pressure.
【００２１】 そして、嵌合部１４の圧接部１２は弾性部材製であるため、シャフト４への圧 入に要する荷重は、圧接部１２が金属等の剛な部材より成る場合に比べて小さく て済み、装着性が良くなる。しかも、嵌合部１４の当接部１３は良伝導性部材製 であるため、スリーブ５のスリーブ環７とシール本体３のリップ部６との摺動発 熱が良好にシャフト４へと伝えられて、高い放熱効果が得られる。Since the press contact portion 12 of the fitting portion 14 is made of an elastic member, the load required for press fitting into the shaft 4 is smaller than that when the press contact portion 12 is made of a rigid member such as metal. It is easy to wear. Moreover, since the contact portion 13 of the fitting portion 14 is made of a highly conductive member, the sliding heat generated between the sleeve ring 7 of the sleeve 5 and the lip portion 6 of the seal body 3 is satisfactorily transmitted to the shaft 4. Thus, a high heat dissipation effect can be obtained.
【００２２】 以下に本考案の他の実施例について説明する。第１の実施例と同一の構成部分 には同一の番号を付して説明を省略する。Another embodiment of the present invention will be described below. The same components as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.
【００２３】 図１(b) は本考案の第２の実施例に係るオイルシールを示しており、第１の実 施例とはリング１１の取付構造及び取付方法が異っている。FIG. 1 (b) shows an oil seal according to a second embodiment of the present invention, which is different from the first embodiment in the mounting structure and mounting method of the ring 11.
【００２４】 即ち、本実施例にあっては、スリーブ環７には第１の実施例のような返り１０ を有していず、カバー９を加硫成形してスリーブ５とカバー９を一体に成形した 後で、スリーブ環７にリング１１を取付けている。That is, in this embodiment, the sleeve ring 7 does not have the barb 10 as in the first embodiment, but the cover 9 is vulcanized and the sleeve 5 and the cover 9 are integrated. After molding, the ring 11 is attached to the sleeve ring 7.
【００２５】 本実施例にあっても第１の実施例と同様の効果を得ることができる。Even in this embodiment, the same effect as that of the first embodiment can be obtained.
【００２６】 図２は本考案の第３の実施例に係るオイルシールを示しており、第１及び第２ の実施例とはリング１１の当接部１３の形状が異っている。FIG. 2 shows an oil seal according to a third embodiment of the present invention, in which the shape of the contact portion 13 of the ring 11 is different from that of the first and second embodiments.
【００２７】 即ち、本実施例におけるリング１１の当接部１３は、その内周面にリング１１ の一端から他端に渡る溝状のスリット１５が、複数設けられている。That is, the contact portion 13 of the ring 11 in this embodiment is provided with a plurality of groove-shaped slits 15 extending from one end to the other end of the ring 11 on the inner peripheral surface thereof.
【００２８】 これによって、シャフト４装着時にリング１１から受ける摩擦力が少なくなる ので、先の実施例と同様の放熱性を有しつつ、装着性に関しては、さらに良好と なる。As a result, the frictional force received from the ring 11 when the shaft 4 is mounted is reduced, so that the mounting property is further improved while having the same heat dissipation as in the previous embodiment.
【００２９】[0029]
以上説明したように本考案に係るオイルシールにあっては、嵌合部の圧接部は 弾性部材製であるため、他の部材への圧入に要する荷重は、圧接部が剛な部材よ り成る場合に比べて小さくて済み、装着性が良い。しかも、嵌合部の当接部のほ うは良伝導性部材製であるため、スリーブとシール本体との摺動発熱が良好に他 方の部材へと伝えられて、高い放熱効果が得られる。 As described above, in the oil seal according to the present invention, since the press-contacting portion of the fitting portion is made of an elastic member, the load required for press-fitting into another member is made of a rigid member at the press-contacting portion. Compared to the case, it is smaller and easy to wear. Moreover, since the contact part of the fitting part is made of a material with good conductivity, sliding heat generation between the sleeve and the seal body is satisfactorily transmitted to the other member, resulting in high heat dissipation effect. ..
