Description
【０００１】[0001]
この考案は玉軸受のシールド装置に関するものである。 The present invention relates to a ball bearing shield device.
【０００２】[0002]
従来の玉軸受のシールド装置は、図３及び図４に示すように、外輪１の軌道面 ２の少なくとも一側の内周面にシールド板３の外周縁を圧入し、該シールド板３ 圧入部の内側面を上記外輪１のシールド壁面４に接触させ、該シールド板３の内 周縁を内輪５の外周面に所要のすき間をおいて対向させた構成であった。上記の シールド板３は図４に示すようなリング状の鋼板であり、外周部が外方へ屈曲さ れて圧入部６となり、その圧入部６の内側に、外輪１のシールド壁面４に接触す る圧接部７が形成される。 As shown in FIGS. 3 and 4, the conventional shield device for a ball bearing is configured such that the outer peripheral edge of the shield plate 3 is press-fitted onto the inner peripheral surface of at least one side of the raceway surface 2 of the outer ring 1, and the press-fitting portion of the shield plate 3 is inserted. The inner side surface of the outer ring 1 is brought into contact with the shield wall surface 4 of the outer ring 1, and the inner peripheral edge of the shield plate 3 is opposed to the outer peripheral surface of the inner ring 5 with a required gap. The shield plate 3 is a ring-shaped steel plate as shown in FIG. 4, and the outer peripheral portion is bent outward to form the press-fitting portion 6, and the inside of the press-fitting portion 6 contacts the shield wall surface 4 of the outer ring 1. A pressure contact portion 7 is formed.
【０００３】[0003]
上記構成のシールド装置は、シールド板３の外周面全体にわたり形成された圧 入部６が弾性変形して外輪１の内周面に圧入されるものであるから、組立時に高 い圧入力が必要となり、また圧入後に外輪１が変形したり、シールド板３が変形 するなどの問題があった。この問題は特に小径の玉軸受の場合に著しい。 In the shield device having the above structure, since the press-fitting portion 6 formed over the entire outer peripheral surface of the shield plate 3 is elastically deformed and press-fitted into the inner peripheral surface of the outer ring 1, a high pressure input is required during assembly. In addition, there is a problem that the outer ring 1 is deformed after the press fitting, and the shield plate 3 is deformed. This problem is remarkable especially in the case of small diameter ball bearings.
【０００４】 このような問題点を解消するために、図５に示すように、シールド板３の外周 縁に径方向の多数のスリット８を形成することにより、圧入力を小さくして、外 輪１の変形を抑制することが知られている。In order to solve such a problem, as shown in FIG. 5, a large number of radial slits 8 are formed on the outer peripheral edge of the shield plate 3 to reduce the pressure input and reduce the outer ring. It is known that the deformation of No. 1 is suppressed.
【０００５】 しかし、上記のスリット８が、外周縁から圧入部７に達する深さで形成される と、圧入部７とシールド壁面４との間にすき間が生じ、グリース洩れを生じるこ とがある。However, if the slit 8 is formed to a depth reaching the press-fitting portion 7 from the outer peripheral edge, a gap may be created between the press-fitting portion 7 and the shield wall surface 4, and grease leakage may occur. .
【０００６】 そこで、この考案は、玉軸受のシールド装置において、シールド板の圧入力が 小さく、しかもシール効果に優れたシールド装置を提供することを課題とする。Therefore, it is an object of the present invention to provide a shield device for a ball bearing, in which the pressure input of the shield plate is small and the seal effect is excellent.
【０００７】[0007]
上記の課題を解決するために、この考案は外輪の軌道面の少なくとも一側の内 周面にシールド板の外周縁を圧入し、該シールド板の圧入部の内側面を上記外輪 のシールド壁面に接触させ、該シールド板の内周縁を内輪の外周面に所要のすき 間をおいて対向させてなる玉軸受のシールド装置において、上記シールド板をシ ールド板本体と、そのシールド板本体の外周縁に等間隔をおいて突設した３乃至 ６箇所の突起により形成し、上記突起を弾性変形させてシールド板を外輪の内周 面に圧入し、上記シールド板本体の外周部内面を外輪のシールド壁面に接触させ た構成としたものである。 In order to solve the above-mentioned problems, the present invention presses the outer peripheral edge of a shield plate into the inner peripheral surface of at least one side of the raceway surface of the outer ring, and the inner side surface of the press-fitting portion of the shield plate is used as the shield wall surface of the outer ring. In a shield device for a ball bearing in which the inner peripheral edge of the shield plate is opposed to the outer peripheral surface of the inner ring with a required clearance, the shield plate is provided with the shield plate body and the outer peripheral edge of the shield plate body. The protrusions are elastically deformed to press the shield plate into the inner peripheral surface of the outer ring, and the inner surface of the outer peripheral portion of the shield plate main body is shielded from the outer ring. It is configured to contact the wall surface.
【０００８】[0008]
上記のシールド装置において、シールド板は、シールド板本体外周に形成した 突起が弾性変形して外輪の内周面に圧入される。また、シールド板本体の外周部 内面がシールド壁面に接触する。 In the above shield device, the shield plate is press-fitted into the inner peripheral surface of the outer ring by elastically deforming the protrusion formed on the outer periphery of the shield plate body. Also, the inner surface of the outer peripheral portion of the shield plate body contacts the wall surface of the shield.
【０００９】[0009]
図１及び図２に示すように、実施例玉軸受のシールド装置において玉軸受の構 成は従来のものと同様であるので、同一部分に同一符号を付するにとどめ、その 説明を省略する。シールド板３はリング状鋼板により形成されたシールド板本体 ９と、そのシールド板本体９の外周縁の等分４箇所に高さ０．１ｍｍ程度の低い 突起１０を形成したものである。 As shown in FIGS. 1 and 2, in the ball bearing shield device of the embodiment, the structure of the ball bearing is the same as that of the conventional one, so that the same parts are allotted with the same reference numerals and the description thereof is omitted. The shield plate 3 is composed of a shield plate body 9 formed of a ring-shaped steel plate, and low protrusions 10 having a height of about 0.1 mm formed at four equally divided outer peripheral edges of the shield plate body 9.
【００１０】 上記の突起１０は外方へ斜めに屈曲され（図１の実線参照）、またシールド板 本体９の外周縁の内面が圧接部７となっている。The above-mentioned protrusion 10 is bent obliquely outward (see the solid line in FIG. 1), and the inner surface of the outer peripheral edge of the shield plate body 9 serves as the pressure contact portion 7.
【００１１】 上記のシールド板３は、その突起１０を弾性変形させて外輪１の内周面に圧入 され（図１の一点鎖線参照）、圧接部７が外輪１のシールド壁面４に接触される 。In the shield plate 3, the protrusion 10 is elastically deformed and press-fitted onto the inner peripheral surface of the outer ring 1 (see the alternate long and short dash line in FIG. 1), and the press contact portion 7 is brought into contact with the shield wall surface 4 of the outer ring 1. .
【００１２】 上記の突起１０は３〜６箇所の範囲で適宜選定される。また各突起１０のシー ルド板本体９の外周からの立上り部１１にゆるやかなアールを形成し、応力の集 中を避けている。The protrusions 10 are appropriately selected within a range of 3 to 6 places. In addition, a gentle radius is formed on the rising portion 11 of each protrusion 10 from the outer periphery of the shield plate body 9 to avoid the concentration of stress.
【００１３】 実施例のシールド装置は以上のごときものであるので、シールド板３は突起１ ０の弾性変形により外輪１に保持され、またシールド板本体９の圧接部７がシー ルド壁４に接触することにより、シール作用を行う。Since the shield device of the embodiment is as described above, the shield plate 3 is held by the outer ring 1 by the elastic deformation of the protrusion 10, and the pressure contact portion 7 of the shield plate body 9 contacts the shield wall 4. By doing so, a sealing action is performed.
【００１４】[0014]
以上のように、この考案は、玉軸受のシールド装置を構成するシールド板を、 シールド板本体とその外周縁の３〜６個の突起により形成したので、外輪への圧 入時は上記の突起のみが弾性変形するだけであるので、従来の場合に比べ、圧入 力が小さくてよく、組立作業が容易になる。従って、外輪及びシールド板自体の 変形が抑制される。また、シールド板本体の外周部内面が全周にわたり外輪のシ ールド壁面に接触するので、シール効果が高い効果がある。 As described above, according to the present invention, the shield plate constituting the shield device for the ball bearing is formed by the shield plate body and the three to six protrusions on the outer peripheral edge thereof. Since only the elastically deforms only, the press-fitting force is smaller than in the conventional case, and the assembling work becomes easy. Therefore, deformation of the outer ring and the shield plate itself is suppressed. Further, since the inner surface of the outer peripheral portion of the shield plate body comes into contact with the shield wall surface of the outer ring over the entire circumference, a high sealing effect is obtained.
