Description
【0001】[0001]
本考案は、自動車のベルト伝導機構等に使用されるプーリ用軸受に関する。 The present invention relates to a pulley bearing used for a belt transmission mechanism of an automobile.
【0002】[0002]
例えば図10に示すように、自動車のベルト伝導機構に使用されるテンション プーリ用軸受では、その重量軽減のため、プーリ本体11と玉軸受12とを一体 化した構成のものが使用されている。プーリ本体11は、一対の断面コ字形のプ レス成形鋼板をリベット13などで突き合わせ結合して一体化したものであり、 ベルト(図示省略)を掛けるための外径側円筒部11aと、玉軸受12の外輪1 2bを嵌合するための内径側円筒部11bとを有する。このテンションプーリ用 軸受はベルトを介して駆動力を受けると、プーリ本体11と玉軸受12の外輪1 2bとが一体となって回転する。 For example, as shown in FIG. 10, a tension pulley bearing used in a belt transmission mechanism of an automobile has a structure in which a pulley body 11 and a ball bearing 12 are integrated to reduce the weight thereof. The pulley main body 11 is made up of a pair of press-formed steel plates having a U-shaped cross-section, butted and joined together by a rivet 13 and the like, and has an outer diameter side cylindrical portion 11a for hanging a belt (not shown) and a ball bearing. It has an inner diameter side cylindrical portion 11b for fitting 12 outer rings 12b. When the tension pulley bearing receives a driving force via the belt, the pulley body 11 and the outer ring 12b of the ball bearing 12 rotate integrally.

近時、自動車業界において、低燃費促進の一環として車体重量の軽量化が積極 的に進められており、自動車部品メーカにあっても部品の軽量化が大きな課題と なっている。その一方で、自動車部品にはコスト性も厳しく要求されるという実 状がある。 Recently, in the automobile industry, the weight reduction of vehicle body has been actively promoted as a part of promotion of low fuel consumption, and the weight reduction of parts has become a big issue even for automobile parts manufacturers. On the other hand, automobile parts are also required to be cost-effective.
【0004】 以上の観点から、図10に示す従来のテンションプーリ用軸受の問題点を指摘 すれば、まず、プーリ本体11の内径側円筒部11bに玉軸受12の外輪12b を嵌合した構成であるから、その重量軽減に限界があるということである。また 、回転部分となるプーリ本体11と外輪12bの重量が大きいということは、そ れだけ慣性が大きく、より多くのトルクを損失することになる。つぎに、プーリ 本体11は一対のプレス成形鋼板を結合一体化したものであるから、相互の芯出 し・結合といった作業が別途必要になり、その分工程増につながることである。 尚、プーリ用軸受の軽量化・低コスト化を図るべく、プーリ本体を樹脂製とし たものもあるが、高温耐久性、クリープといった問題を内在しており、その用途 は限定されている。From the above point of view, pointing out the problem of the conventional tension pulley bearing shown in FIG. 10, first, the outer ring 12b of the ball bearing 12 is fitted to the inner diameter side cylindrical portion 11b of the pulley body 11. Therefore, there is a limit to the weight reduction. Further, the large weight of the pulley body 11 and the outer ring 12b, which are the rotating parts, means that the inertia is correspondingly large and more torque is lost. Next, since the pulley main body 11 is formed by integrally combining a pair of press-formed steel plates, it is necessary to separately perform operations such as mutual centering and connection, which leads to an increase in the number of processes. Some pulley bodies are made of resin in order to reduce the weight and cost of bearings for pulleys, but their use is limited due to the inherent problems of high temperature durability and creep.
【0005】 本考案は、上記問題点に鑑み、プーリ用軸受の軽量化および低コスト化を図ろ うとするものである。さらに、本考案はプーリ用軸受の振動・騒音特性の向上を も図ろうとするものである。In view of the above problems, the present invention is intended to reduce the weight and cost of a pulley bearing. Further, the present invention is intended to improve the vibration and noise characteristics of the pulley bearing.
【0006】[0006]
請求項1のプーリ用軸受は、ベルトを掛けるための外径側円筒部と、外径側円 筒部より内径側に空間部を隔てて位置する内径側円筒部と、外径側円筒部と内径 側円筒部とを一方の端面側において連続させる連続部とを有する断面コ字形のプ レス一体成形環体からなるプーリ本体と、内径側円筒部に装着される玉軸受とで 構成されるものであって、内径側円筒部の内径面に玉軸受のボールを転動自在に 案内する外側軌道面を直接形成したものである。 According to another aspect of the present invention, there is provided a pulley bearing, wherein an outer diameter side cylindrical portion for hanging a belt, an inner diameter side cylindrical portion located on the inner diameter side of the outer diameter side cylindrical portion with a space therebetween, and an outer diameter side cylindrical portion. Consists of a pulley body consisting of a press integrally molded ring body with a U-shaped cross section having a continuous part that connects the inner diameter side cylindrical part on one end face side, and a ball bearing mounted on the inner diameter side cylindrical part The outer raceway surface for rollingly guiding the balls of the ball bearing is directly formed on the inner diameter surface of the inner diameter side cylindrical portion.
【0007】 請求項2のプーリ用軸受は、請求項1の構成において、外径側円筒部と内径側 円筒部との間の空間部に弾性体を介在させたものである。According to a second aspect of the present invention, in the structure of the first aspect, an elastic body is interposed in a space between the outer diameter side cylindrical portion and the inner diameter side cylindrical portion.
【0008】[0008]
プーリ本体はプレス一体成形によるものであるから、低コストである。また、 プーリ本体の内径側円筒部に玉軸受のボールを転動自在に案内する外側軌道面を 直接形成し、内径側円筒部に軸受外輪を兼ねさせることにより、より一層の軽量 化、トルク損失の減少を図ることができる。 Since the pulley main body is formed by press integral molding, the cost is low. In addition, the outer raceway surface that guides the balls of the ball bearing to roll freely is formed directly on the inner diameter side cylindrical part of the pulley body, and the inner diameter side cylindrical part also serves as the bearing outer ring, further reducing weight and torque loss. Can be reduced.
【0009】 外径側円筒部と内径側円筒部との間の空間部に弾性体を介在させることにより 、ベルト荷重が弾性体によって支持されるので、プーリ本体の強度、剛性が向上 する。さらに、運転時にベルトを介して伝わる振動が弾性体の適度の弾性変形に よって吸収される。Since the belt load is supported by the elastic body by interposing the elastic body in the space between the outer diameter side cylindrical portion and the inner diameter side cylindrical portion, the strength and rigidity of the pulley main body is improved. Further, the vibration transmitted through the belt during operation is absorbed by the appropriate elastic deformation of the elastic body.

A flange 1a1 for belt design is provided on the other end surface of the outer diameter side cylindrical portion 1a, and a single row of outer track surface 1b1 is provided on the inner diameter surface of the inner diameter side cylindrical portion 1b.
【0013】 玉軸受2は、軸体例えば中空状の軸体3の外径面に嵌着される内輪2bと、単 列の外側軌道面1b1と内輪2bの外径面に形成された単列の内側軌道面2b1 との間に転動自在に介在する複数のボール2cと、ボール2cを円周等間隔に保 持する保持器2dと、内径側円筒部1bの内径面に嵌着され、軸受内を密封する 一対のシール部材2eとで構成されている。The ball bearing 2 includes an inner ring 2b fitted to the outer diameter surface of a shaft body such as a hollow shaft body 3, a single row outer raceway surface 1b1 and a single row formed on the outer diameter surface of the inner ring 2b. A plurality of balls 2c which are rotatably interposed between the inner raceway surface 2b1 and the inner raceway surface 2b1, a retainer 2d which holds the balls 2c at equal intervals around the circumference, and an inner diameter surface of the inner diameter side cylindrical portion 1b. It is composed of a pair of seal members 2e for sealing the inside of the bearing.
【0014】 プーリ本体1は、図2に示すように、1枚の鋼板素材1’からプレス加工によ り外径側円筒部1’aと内径側円筒部1’b等を成形した後、内径側円筒部1’ bの他方の端面の底抜および外側軌道面1’b1の成形加工を行なって形成した ものである。As shown in FIG. 2, the pulley main body 1 is obtained by forming an outer diameter side cylindrical portion 1′a, an inner diameter side cylindrical portion 1′b and the like from a single steel plate material 1 ′ by press working, It is formed by punching out the other end surface of the inner diameter side cylindrical portion 1'b and forming the outer raceway surface 1'b1.
【0015】 図3に示す実施例は、複列の玉軸受2を使用したものである。プーリ本体1は 、図1に示すものと同様に、1枚の鋼板素材1’をプレス成形したプレス一体成 形環体である。内輪2bの外径面には複列の内側軌道面2b1が形成され、内径 側円筒部1bの内径面には複列の外側軌道面1b1が形成されている。この実施 例では、ボール2cと内側軌道面2b1および外側軌道面1b1との接触が、ア ンギュラコンタクトになっている。The embodiment shown in FIG. 3 uses a double row ball bearing 2.

A double row inner raceway surface 2b1 is formed on the outer diameter surface of the inner ring 2b, and a double row outer raceway surface 1b1 is formed on the inner diameter surface of the inner diameter side cylindrical portion 1b. In this embodiment, the contact between the ball 2c and the inner raceway surface 2b1 and the outer raceway surface 1b1 is an angular contact.
【0016】 図4に示す実施例は、図1に示す構成において、空間部1dに弾性体例えば樹 脂体5を介在させたものであり、図5に示す実施例は、図3に示す構成において 、空間部1dに樹脂体5を介在させたものである。プーリ本体1の外径側円筒部 1aに作用するベルト荷重が樹脂体5によって支持されることにより、プーリ本 体1の強度、剛性が向上する。また、運転時にベルトを介して伝わる振動が樹脂 体5の適度の弾性変形によって吸収される。したがって、この実施例のテンショ ンプーリ用軸受は、極めて良好な振動・音響特性を有する。特に、冷時には、軸 方向自励振動による異音(汽笛音)が発生する場合があり、このような場合、特 に有効である。尚、樹脂体5は樹脂材を空間部1dに射出成形したものである。 図6に示す実施例は、樹脂体5を空間部1dの一部分にのみ介在させたもので ある。The embodiment shown in FIG. 4 is obtained by interposing an elastic body such as a resin body 5 in the space 1d in the structure shown in FIG. 1. The embodiment shown in FIG. 5 has the structure shown in FIG. In the above, the resin body 5 is interposed in the space 1d. By supporting the belt load acting on the outer diameter side cylindrical portion 1a of the pulley body 1 by the resin body 5, the strength and rigidity of the pulley body 1 are improved. Further, the vibration transmitted through the belt during operation is absorbed by the appropriate elastic deformation of the resin body 5. Therefore, the tension pulley bearing of this embodiment has extremely good vibration and acoustic characteristics. Especially when it is cold, abnormal noise (steam whistle) may occur due to axial self-excited vibration, which is especially effective in such a case. The resin body 5 is a resin material injection-molded in the space 1d. In the embodiment shown in FIG. 6, the resin body 5 is interposed only in a part of the space 1d.

【0020】[0020]
以上説明したように、本考案によれば、プーリ本体をプレス一体成形環体とし たので、図10に示す結合一体のプーリ本体に比べ、芯出し・結合作業が不要と なり、工程の簡素化並びに低コスト化を図ることができる。また、プーリ本体の 内径側円筒部に外側軌道面を直接形成し、内径側円筒部に軸受外輪を兼ねさせる 構成としたので、より一層の重量軽減を図ることができると同時に、回転部分の 慣性が減少するので、トルク損失を減少させることができる。さらに、外径側円 筒部と内径側円筒部との間の空間部に弾性体を介在させることにより、プーリ本 体の強度、剛性が向上し、しかも、運転時にベルトを介して伝わる振動が樹脂体 の適度の弾性変形によって吸収されるので、振動・音響特性を従来に比べ著しく 向上させることができる。 As described above, according to the present invention, since the pulley main body is the press-integrated ring body, the centering and connecting work is unnecessary as compared with the integrated pulley body shown in FIG. 10, and the process is simplified. In addition, cost reduction can be achieved. In addition, the outer raceway surface is directly formed on the inner diameter side cylindrical part of the pulley body, and the inner diameter side cylindrical part also serves as the bearing outer ring, so that the weight can be further reduced and the inertia of the rotating part can be achieved at the same time. Is reduced, the torque loss can be reduced. Furthermore, by interposing an elastic body in the space between the outer diameter side cylindrical portion and the inner diameter side cylindrical portion, the strength and rigidity of the pulley main body is improved, and the vibration transmitted through the belt during operation is reduced. Since it is absorbed by the moderate elastic deformation of the resin body, it is possible to significantly improve vibration and acoustic characteristics as compared with the conventional one.
