Description

本発明は、例えば、自動車用エンジンの補機或いはカムシャフトを駆動するベルトやタイミングベルト等が掛け渡される樹脂プーリが外輪に一体に成形される樹脂プーリ用軸受に関する。   The present invention relates to a bearing for a resin pulley in which, for example, a resin pulley around which an auxiliary machine for an automobile engine or a belt for driving a camshaft, a timing belt or the like is stretched is formed integrally with an outer ring.

自動車のエンジン補機類を駆動するベルトの案内用プーリとしては、その質量軽減及び製造コスト抑制のため、転がり軸受の外輪に樹脂プーリを一体に成形した樹脂プーリ用軸受が採用されている（例えば、特許文献１および特許文献２参照）。   As a pulley for guiding belts for driving engine accessories of automobiles, a resin pulley bearing in which a resin pulley is integrally formed on an outer ring of a rolling bearing is adopted in order to reduce mass and reduce manufacturing costs (for example, Patent Document 1 and Patent Document 2).

この樹脂プーリ用軸受では、転がり軸受の素材である軸受鋼（ＳＵＪ２等）の防錆能力が低いことから、外輪に防錆油を塗布し、樹脂プーリの成形前に該防錆油を外輪から除去するようにしている。   In this resin pulley bearing, the bearing steel (SUJ2 etc.), which is the material of the rolling bearing, has low rust prevention capability. Therefore, apply rust prevention oil to the outer ring and remove the rust prevention oil from the outer ring before molding the resin pulley. Try to remove.

しかし、上記従来の技術では、転がり軸受の外輪に樹脂プーリを成形する際、外輪に防錆油が残存していると、成形時に溶融樹脂が防錆油の油分を巻き込んでしまうため、樹脂プーリの強度が劣化してしまう可能性がある。   However, in the above prior art, when the resin pulley is molded on the outer ring of the rolling bearing, if the rust preventive oil remains in the outer ring, the molten resin entrains the oil component of the rust preventive oil at the time of molding. May deteriorate in strength.

また、転がり軸受の外輪に樹脂プーリを成形する前に、外輪に防錆油を塗布する工程および外輪から防錆油を除去する工程が必須となるため、作業工程が増えてコスト低下を妨げる原因になる。   Also, before molding resin pulleys on the outer ring of rolling bearings, the process of applying rust-preventing oil to the outer ring and the process of removing rust-preventing oil from the outer ring are indispensable. become.

本発明は、このような不都合を解消するためになされたものであり、その目的は、樹脂プーリの強度劣化を防止することができるとともに、作業工程を減らして製造コストを低くすることができる樹脂プーリ用軸受を提供することにある。   The present invention has been made in order to eliminate such inconveniences, and an object of the present invention is to prevent the deterioration of the strength of the resin pulley and reduce the manufacturing process by reducing the work process. The object is to provide a pulley bearing.

以下、本発明に係る樹脂プーリ用軸受の一実施形態について、図面を参照して詳細に説明する。
図１は本発明に係る樹脂プーリ用軸受の一実施形態を説明するための断面図、図２は図１の側面図である。 Hereinafter, an embodiment of a resin pulley bearing according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a cross-sectional view for explaining an embodiment of a resin pulley bearing according to the present invention, and FIG. 2 is a side view of FIG.

本実施形態の樹脂プーリ用軸受１０は、図１に示すように、内周面に外輪軌道面１１ａを有する外輪１１と、外周面に内輪軌道面１２ａを有する内輪１２と、外輪軌道面１１ａと内輪軌道面１２ａとの間に転動自在に配設される複数の玉（転動体）１３と、玉１３を円周方向に等間隔に保持する保持器１４と、外輪１１の軸方向の両端部内周部に装着され、軸受空間と外部との間をシールするシール部材１５と、を備える。   As shown in FIG. 1, the resin pulley bearing 10 of the present embodiment includes an outer ring 11 having an outer ring raceway surface 11a on an inner peripheral surface, an inner ring 12 having an inner ring raceway surface 12a on an outer peripheral surface, and an outer ring raceway surface 11a. A plurality of balls (rolling elements) 13 that are rotatably arranged between the inner ring raceway surface 12a, a cage 14 that holds the balls 13 at equal intervals in the circumferential direction, and both ends of the outer ring 11 in the axial direction. And a seal member 15 which is mounted on the inner periphery of the unit and seals between the bearing space and the outside.

また、外輪１１の外周面には、樹脂プーリ１６が一体に形成されている。
この樹脂プーリ１６は、図１および図２に示すように、外輪１１の外周面に外嵌状態で一体に固定される内筒１７と、内筒１７と略同心配置されて、自動車用エンジンの補機やカムシャフトを駆動するベルト等が掛け渡される外筒１８と、外筒１８と内筒１７との間を連結する円環状板１９と、内筒１７と外筒１８との間で円環状板１９に放射状にして設けられた補強リブ２０と、を備える。 A resin pulley 16 is integrally formed on the outer peripheral surface of the outer ring 11.
As shown in FIGS. 1 and 2, the resin pulley 16 is disposed substantially concentrically with the inner cylinder 17 that is integrally fixed to the outer circumferential surface of the outer ring 11 and the inner cylinder 17. An outer cylinder 18 on which an auxiliary machine, a belt for driving a camshaft and the like are stretched, an annular plate 19 connecting the outer cylinder 18 and the inner cylinder 17, and a circle between the inner cylinder 17 and the outer cylinder 18 Reinforcing ribs 20 provided radially on the annular plate 19.

また、樹脂プーリ１６は、外輪１１を金型内に芯出し固定し、例えばインサート成形等の射出性径により、この金型内のキャビティーに溶融樹脂を充填し、これを固化させることによって、外輪１１の外周面に一体的に形成される。なお、樹脂としては、ナイロン系樹脂、フェノール系樹脂等を用いることができる。
なお、図２において符号２１は、樹脂成形時のピンゲート部とされる。 Further, the resin pulley 16 centers and fixes the outer ring 11 in the mold, and fills the cavity in the mold with a molten resin by an injection diameter such as insert molding, for example, and solidifies it. It is integrally formed on the outer peripheral surface of the outer ring 11. As the resin, nylon resin, phenol resin, or the like can be used.
In FIG. 2, reference numeral 21 denotes a pin gate portion during resin molding.

そして、本実施形態では、外輪１１の素材として軸受鋼（ＳＵＪ２等）を用い、該外輪１１の少なくとも樹脂プーリ１６が接触する部分に、予めフッ素被膜等の表面被膜処理を施している。   And in this embodiment, bearing steel (SUJ2 etc.) is used as a raw material of the outer ring | wheel 11, and surface coating processes, such as a fluorine film, are performed in advance to the part which the resin pulley 16 of this outer ring | wheel 11 contacts.

以上説明したように、本実施形態の樹脂プーリ用軸受１０によれば、外輪１１の少なくとも樹脂プーリ１６が接触する部分に、予めフッ素被膜等の表面被膜処理を施しているので、防錆能力が低い軸受鋼からなる外輪１１に対して、従来のように、防錆油を塗布することなく、フッ素被膜等による防錆性を付与することができる。   As described above, according to the resin pulley bearing 10 of the present embodiment, a surface coating treatment such as a fluorine coating is applied in advance to at least a portion of the outer ring 11 that is in contact with the resin pulley 16. The outer ring 11 made of low bearing steel can be provided with rust prevention by a fluorine coating or the like without applying rust prevention oil as in the prior art.

これにより、樹脂プーリ１６の成形時に溶融樹脂が防錆油の油分を巻き込んでしまうのを回避することができ、樹脂プーリ１６の強度が劣化するのを防止することができる。   Thereby, it can avoid that molten resin entrains the oil component of antirust oil at the time of shaping | molding of the resin pulley 16, and it can prevent that the intensity | strength of the resin pulley 16 deteriorates.

また、外輪１１に防錆油を塗布する作業および外輪１１から防錆油を除去する作業が不要になるため、作業工程が減って製造コストを低くすることができ、安価な樹脂プーリ用軸受を提供することができる。   Further, since the work for applying the antirust oil to the outer ring 11 and the work for removing the antirust oil from the outer ring 11 are not required, the work process can be reduced and the manufacturing cost can be reduced. Can be provided.

なお、本発明の外輪、内輪、転動体、表面処理被膜等の構成は、上記一実施形態に例示したもの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において適宜変更可能である。   Note that the configurations of the outer ring, inner ring, rolling element, surface treatment film, and the like of the present invention are not limited to those exemplified in the above embodiment, and can be appropriately changed without departing from the gist of the present invention. .

例えば、上記実施形態では、外輪１１の表面被膜処理としてフッ素被膜処理を例示したが、これに限定されず、硬質クロメート被膜、ＤＬＣ（ダイヤモンド ライク カーボン）被膜等の表面被膜処理を施してもよい。   For example, in the above-described embodiment, the fluorine coating process is exemplified as the surface coating process of the outer ring 11. However, the present invention is not limited to this, and a surface coating process such as a hard chromate coating or a DLC (diamond-like carbon) coating may be performed.

また、上記実施形態では、防錆能力が低い軸受鋼からなる外輪１１に表面被膜処理を施して防錆性を付与する場合を例示したが、これに代えて、外輪１１の素材として防錆能力の高いステンレス鋼材又はセラミックス材を用いてもよい。このようにすると、外輪１１に防錆油を塗布する作業および外輪１１から防錆油を除去する作業が不要になるのは勿論のこと、外輪１１に表面被膜処理も施す必要がないため、樹脂プーリの成形時における手間を更に省くことができる。   Moreover, in the said embodiment, although the case where surface coating process was given to the outer ring | wheel 11 which consists of bearing steel with a low rust prevention capability and rust prevention property was provided, it replaced with this and the rust prevention capability is used as the raw material of the outer ring | wheel 11 instead. High stainless steel material or ceramic material may be used. In this case, the work for applying the rust-preventing oil to the outer ring 11 and the work for removing the rust-preventing oil from the outer ring 11 are not required. It is possible to further save time and trouble when forming the pulley.

この場合、ステンレス鋼材としては、例えば、ＳＵＳ４４０Ｃを例示することができる。一方、セラミックス材としては、窒化珪素系、アルミナ系等を例示することができる。   In this case, as a stainless steel material, SUS440C can be illustrated, for example. On the other hand, examples of the ceramic material include silicon nitride and alumina.

その他、上記で例示した樹脂プーリ、外輪軌道面、外輪、内輪軌道面、内輪、転動体等の材質、形状、寸法、形態、数、配置箇所等は本発明を達成できるものであれば任意であり、限定されない。   In addition, the materials, shapes, dimensions, forms, numbers, locations, etc. of the resin pulley, outer ring raceway surface, outer ring, inner ring raceway surface, inner ring, rolling element, etc. exemplified above are arbitrary as long as they can achieve the present invention. Yes, but not limited.
