Description
【０００１】[0001]
この考案は、自動調心ころ軸受または自動調心玉軸受にシールを設けたシール 付調心型転がり軸受に関する。 The present invention relates to a self-aligning rolling bearing with a seal in which a self-aligning roller bearing or a self-aligning ball bearing is provided with a seal.
【０００２】[0002]
調心型の転がり軸受は、調心作用によって外輪と内輪の軸心にずれが生じるた め、シールを設けることが難しく、軸受自体にシールを施したものはあまり実用 化されていない。しかし、シール機能を要望される場合があり、従来、シール付 きの調心型転がり軸受として図６（Ａ）に示すもの（特公昭５５−２１２１６号 公報）や、同図（Ｂ）〜（Ｄ）に示すもの等が各々提案されている。 In a centering type rolling bearing, it is difficult to provide a seal because the axial center of the outer ring and the inner ring are misaligned by the centering action, and bearings with a sealed seal have not been put to practical use. However, there is a case where a sealing function is required, and conventionally, a centering type rolling bearing with a seal is shown in FIG. 6 (A) (Japanese Patent Publication No. 55-21216), and FIGS. Those shown in D) have been proposed.
【０００３】 同図（Ａ）の軸受は、内輪５１および外輪５２の幅面に内側リング５３および 外側リング５４を各々取付け、両リング５３，５４と繊維材の被覆５５とでシー ル５６を構成したものである。両リング５３，５４は、調心動作にかかわらずに 被覆５５の挟み込みが維持されるように、外側へ突出した屈曲板状に形成されて いる。５７は転動体である。この構成によると、シール５６による確実なグリー ス漏れ防止および塵埃の侵入防止効果が得られる。In the bearing shown in FIG. 1A, an inner ring 53 and an outer ring 54 are attached to the width surfaces of an inner ring 51 and an outer ring 52, respectively, and a seal 56 is composed of both rings 53 and 54 and a fiber material coating 55. It is a thing. Both rings 53 and 54 are formed in a bent plate shape protruding outward so that the sandwiching of the cover 55 is maintained regardless of the centering operation. 57 is a rolling element. With this configuration, the seal 56 can reliably prevent the grease from leaking and prevent dust from entering.
【０００４】 同図（Ｂ）〜（Ｄ）の例は、構造の簡易化や取扱いの容易を図ったものであり 、各々金属板製のリング状のシール板５８〜６０を設けている。シール板５８〜 ６０の取付け構造は次の構造としてある。すなわち、（Ｂ）の例は、シール板５ ８のフランジ５８ａが入るように外輪５２の幅を広げ、外輪５２内にシール板５ ８を圧入してある。（Ｃ）の例はシール板５９のフランジ５９ａを外輪５２の外 径に圧入し、そのフランジ先端をかしめ止めしてある。同図（Ｄ）の例は、シー ル板６０のフランジ６０ａを内輪５１の内径面に圧入し、フランジ先端をかしめ 止めしてある。The examples of FIGS. 1B to 1D are for simplifying the structure and facilitating handling, and ring-shaped sealing plates 58 to 60 made of metal plates are provided, respectively. The mounting structure of the seal plates 58 to 60 is as follows. That is, in the example of (B), the width of the outer ring 52 is widened so that the flange 58a of the seal plate 58 is inserted, and the seal plate 58 is press-fitted into the outer ring 52. In the example of (C), the flange 59a of the seal plate 59 is press fitted into the outer diameter of the outer ring 52, and the tip of the flange is caulked. In the example of FIG. 3D, the flange 60a of the seal plate 60 is press-fitted into the inner diameter surface of the inner ring 51, and the tip of the flange is caulked.
【０００５】[0005]
図６（Ａ）の例は、シール５６が内外輪５１，５２から幅方向に大きく突出す るため、横置き状態で段積みすることができず、また柔らかな被覆５５の保護の ために、横置きするだけでも支障を生じる場合がある。そのため取扱に不便であ る。 In the example of FIG. 6 (A), since the seal 56 projects greatly from the inner and outer rings 51, 52 in the width direction, the seals cannot be stacked in a horizontal state, and in order to protect the soft cover 55, Even horizontal placement may cause problems. Therefore, it is inconvenient to handle.
【０００６】 図６（Ｂ）〜（Ｄ）の例は、取扱上の問題はないが、次のような欠点がある。 すなわち（Ｂ）の例は、軸受幅が大きく広がるという問題点があり、（Ｃ）の例 はシール板５９が保持器６１と干渉して調心性が損なわれる。また、（Ｄ）の例 は内輪５１の内径の嵌め合い面が小さくなるため、クリープを起こし易いという 問題点がある。The examples shown in FIGS. 6B to 6D have no problem in handling, but have the following drawbacks. That is, in the example of (B), there is a problem that the bearing width is widened, and in the example of (C), the seal plate 59 interferes with the cage 61, and the aligning property is deteriorated. Further, in the example of (D), since the fitting surface of the inner diameter of the inner ring 51 becomes small, there is a problem that creep easily occurs.
【０００７】 この考案の目的は、シール材の突出がなくて取扱性が良く、またシール材の取 付けのために軸受幅が広がったり、調心性が損なわれたりする等の支障を伴うこ とのないシール付調心型転がり軸受を提供することである。The object of the present invention is that the sealing material does not project and the handling is good, and the mounting of the sealing material causes problems such as widening of the bearing width and loss of alignment. It is an object of the present invention to provide a self-aligning type rolling bearing with a seal.
【０００８】[0008]
この考案のシール付調心型転がり軸受は、内輪と外輪との間の隙間を塞ぐリン グ板状のシール材を、内輪の外径面に取付けたものである。 The centering type rolling bearing with a seal of the present invention is one in which a ring-plate-shaped sealing material that closes the gap between the inner ring and the outer ring is attached to the outer diameter surface of the inner ring.
【０００９】[0009]
この構成によると、シール材を内輪の外径面に取付けたため、シール材が軸受 の幅方向に突出せず、そのため軸受の段積み等が可能で取扱性が良い。内輪の外 径面は、調心型の軸受では、側縁部と転動体との間の幅が外輪側よりも広くなっ ており、そのため軸受幅をほとんど広げずにシール材の取付けが行える。また、 シール材は内輪に取付けたため、外輪側に取付ける場合と異なり、調心動作によ ってシール材が保持器や転動体に干渉することがない。 According to this structure, since the sealing material is attached to the outer diameter surface of the inner ring, the sealing material does not project in the width direction of the bearing, and therefore, the bearings can be stacked and the handling is good. In the outer diameter surface of the inner ring, in a centering type bearing, the width between the side edge and the rolling element is wider than that on the outer ring side, so the seal material can be installed without widening the bearing width. Also, since the seal material is attached to the inner ring, unlike the case where it is attached to the outer ring side, the seal material does not interfere with the cage and rolling elements due to the centering operation.
【００１０】[0010]
【実施例】 この考案の一実施例を図１および図２に基づいて説明する。この実施例は、自 動調心ころ軸受に適用した例である。 内輪１と外輪２の間に、保持器３で保持されたスフェリカルころ型の転動体４ を２列に設け、内輪１の外径面の両端近傍にシール取付溝５を形成してある。シ ール材６は、内径部に内向きのフランジ６ａを有するリング状の金属板からなり 、内輪１の外径面に圧入すると共に、フランジ先端の係止突条６ｂ（図２）をシ ール取付溝５に係合させて内輪１に取付けてある。シール材６の外径は、外輪２ の幅面における内径よりも僅かに小径に形成されている。シール材６のフランジ ６ａの外径面は、保持器３の案内面としてある。Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 and 2. This embodiment is an example applied to a self-aligning roller bearing. Spherical roller type rolling elements 4 held by a cage 3 are provided in two rows between the inner ring 1 and the outer ring 2, and seal mounting grooves 5 are formed near both ends of the outer diameter surface of the inner ring 1. The seal member 6 is composed of a ring-shaped metal plate having an inwardly facing flange 6a on its inner diameter portion, is press-fitted into the outer diameter surface of the inner ring 1, and is provided with a locking projection 6b (Fig. 2) at the end of the flange. It is attached to the inner ring 1 by engaging with the base mounting groove 5. The outer diameter of the sealing material 6 is formed to be slightly smaller than the inner diameter of the width surface of the outer ring 2. The outer diameter surface of the flange 6 a of the sealing material 6 serves as a guide surface for the cage 3.
【００１１】 この構成によると、シール材３を内輪１の外径面に取付けたため、シール材３ が軸受の幅方向に突出せず、そのため軸受の横置きや段積みが可能で、取扱性が 良い。また、１枚板のシール材３を圧入して取付けただけの構造であるため、構 造が簡単でコストが易くできる。According to this configuration, since the seal material 3 is attached to the outer diameter surface of the inner ring 1, the seal material 3 does not project in the width direction of the bearing, and therefore, the bearing can be placed horizontally or stacked, and handleability is improved. good. In addition, since the structure is such that only one sheet of the sealing material 3 is press-fitted and attached, the structure is simple and the cost can be increased.
【００１２】 また、内輪１の外径面にシール材６を取付けているため、軸受幅を余分に広げ る必要がない。すなわち、自動調心ころ軸受では、内輪１の外径面における側縁 部と転動体４との間の幅は外輪側よりも広くなっており、この部分を取付けに利 用することにより、軸受幅をほとんど広げずにシール材３の取付けが行える。そ のため、シール無しタイプの自動調心ころ軸受用のハウジングや軸をそのままこ の実施例の軸受に使用できる。さらに、シール材３は内輪１に取付けたため、外 輪２側に取付ける場合と異なり、調心動作により内輪１と外輪２の軸がずれても 、シール材６が保持器３や転動体４に干渉することがない。また、図６（Ｄ）の 従来例と異なり、シール材６で内輪１の嵌め合い面が狭められることもない。Since the seal material 6 is attached to the outer diameter surface of the inner ring 1, it is not necessary to increase the bearing width. That is, in the self-aligning roller bearing, the width between the side edge portion on the outer diameter surface of the inner ring 1 and the rolling element 4 is wider than that on the outer ring side. By utilizing this portion for mounting, the bearing The seal material 3 can be attached without widening the width. Therefore, the housing and shaft for the self-aligning roller bearing of the unsealed type can be used as it is for the bearing of this embodiment. Further, since the seal material 3 is attached to the inner ring 1, unlike the case where the seal material 3 is attached to the outer ring 2 side, even if the axes of the inner ring 1 and the outer ring 2 are deviated by the centering operation, the seal material 6 is retained on the cage 3 and the rolling elements 4. There is no interference. Further, unlike the conventional example of FIG. 6D, the fitting surface of the inner ring 1 is not narrowed by the sealing material 6.
【００１３】 なお、シール材６は非接触型のものであるため、シール性は密閉型のものに比 べて劣るが、前記のように取扱性が良く構造が簡単であるため、そのような使用 目的に好適に使用できる。調心動作により内輪１が外輪２に対して傾いたときに 、シール材６の外径端が外輪２から軸方向に離れて隙間を生じることが懸念され るが、例えば外径が１００mmφのシール材６において、０．５度の内輪１の傾き が生じても、シール材６の外径端の軸方向移動距離は０．４mm程度であるため、 シール性能に大きな影響を及ぼすことはない。Since the sealing material 6 is a non-contact type, the sealing performance is inferior to that of the closed type, but as described above, it is easy to handle and the structure is simple. It can be suitably used for the intended purpose. When the inner ring 1 is tilted with respect to the outer ring 2 due to the centering operation, there is a concern that the outer diameter end of the sealing material 6 may be separated from the outer ring 2 in the axial direction to create a gap. Even if the inner ring 1 is tilted by 0.5 degrees in the material 6, since the axial movement distance of the outer diameter end of the sealing material 6 is about 0.4 mm, the sealing performance is not significantly affected.
【００１４】 調心動作による隙間の増大防止が要望される場合は、図３（Ａ）に示すように シール材６の外径端に内側へ屈曲した環状の屈曲部６ｄを設ければ良い。これに より、図３（Ｂ）のように内輪１に傾きが生じても、シール材６の外径端と外輪 ２との間の隙間の増大が防止され、シール性が確保される。If it is desired to prevent an increase in the gap due to the centering operation, an inwardly bent annular bent portion 6d may be provided at the outer diameter end of the sealing material 6 as shown in FIG. 3 (A). As a result, even if the inner ring 1 is tilted as shown in FIG. 3B, an increase in the gap between the outer diameter end of the sealing material 6 and the outer ring 2 is prevented, and the sealing performance is secured.
【００１５】 なお、図４に示すようにシール材６を芯金６ｅとこれを被覆するゴム等の弾性 被覆材６ｆとで構成し、その外周のリップ部６ｇを外輪２の内径面に接触させる ようにしても良い。これにより、より一層のシール性能の向上が図れる。As shown in FIG. 4, the seal member 6 is composed of a core metal 6e and an elastic coating material 6f such as rubber for covering the core metal 6e, and the lip portion 6g on the outer periphery thereof is brought into contact with the inner diameter surface of the outer ring 2. You may do it. As a result, the sealing performance can be further improved.
【００１６】 図５はさらに他の実施例を示す。この例は、内輪１が外鍔１ａを有する形式の 自動調心ころ軸受である。この場合は、内輪１の外鍔１ａの外径面にシール材６ を装着する。保持器７にはくし歯形のものを使用してある。このように構成した 場合も、図１の実施例における取扱いの容易性や、その他の各効果が得られる。FIG. 5 shows still another embodiment. This example is a self-aligning roller bearing in which the inner ring 1 has an outer collar 1a. In this case, the seal material 6 is attached to the outer diameter surface of the outer collar 1a of the inner ring 1. The cage 7 has a comb-teeth shape. Even in the case of such a configuration, the ease of handling and other effects in the embodiment of FIG. 1 can be obtained.
【００１７】 なお、前記各実施例は自動調心ころ軸受に適用した場合につき説明したが、こ の考案は自動調心玉軸受にも適用することができる。Although each of the embodiments has been described as applied to a self-aligning roller bearing, the invention can be applied to a self-aligning ball bearing.

この考案のシール付調心型転がり軸受は、シール材を内輪の外径面に取付けた ため、シール材が軸受の幅方向に突出せず、そのため軸受の段積み等が可能で取 扱性が良い。また、シール材を内輪の外径面に取付けたため、軸受幅をほとんど 広げずにシール材の取付けが行え、しかもシール材が保持器や転動体に干渉して 調心性が損なわれることがない。 Since the centering type rolling bearing with seal of this invention has the sealing material attached to the outer diameter surface of the inner ring, the sealing material does not project in the width direction of the bearing, so that the bearings can be stacked and handled. good. In addition, since the seal material is attached to the outer diameter surface of the inner ring, the seal material can be attached without widening the bearing width, and the seal material does not interfere with the cage and the rolling elements to impair the alignment.
