Description
【０００１】[0001]
この考案は、外輪の外側にフランジ部材を圧入固定したフランジ付シェル形軸 受に関する。 The present invention relates to a flanged shell type bearing in which a flange member is press-fitted and fixed to the outside of an outer ring.
【０００２】[0002]
各種事務機器におけるローラは、鋼板フレームによる支持のため、軸方向の固 定が行なえるフランジ付の軸受が必要になる。 Since the rollers in various office equipment are supported by steel plate frames, bearings with flanges that can be fixed in the axial direction are required.
【０００３】 従来は図４に示すように、外周にフランジ１を設けたメタル軸受２を用い、鋼 板フレーム３の孔４にメタル軸受２をフランジ１が鋼板フレーム３の一面に重な るよう挿入し、メタル軸受２でローラ５を回動自在に支持するようにしていたが 、最近では、より速く情報を伝達できるように高速化が求められ、上記のような すべり軸受ではこれに対応できなくなっている。Conventionally, as shown in FIG. 4, a metal bearing 2 provided with a flange 1 on the outer circumference is used, and a metal bearing 2 is provided in a hole 4 of a steel plate frame 3 so that the flange 1 overlaps one surface of the steel plate frame 3. The roller 5 is inserted into the roller bearing 5 so that it can be rotatably supported by the metal bearing 2. However, recently, it has been required to increase the speed so that information can be transmitted more quickly. It's gone.
【０００４】 そこで図５のように、すべりを転がりにすることで高速化を図るには、先ず玉 軸受６の使用が考えられるが、先にも述べたように、軸方向の固定が必要になる ため、外輪７の外周にフランジ８を設けなければならない。Therefore, as shown in FIG. 5, in order to increase the speed by rolling the slide, it is conceivable to use the ball bearing 6 first, but as described above, it is necessary to fix the bearing in the axial direction. Therefore, the flange 8 must be provided on the outer circumference of the outer ring 7.
【０００５】[0005]
しかし、外輪７にフランジ８を設けた玉軸受６は、汎用玉軸受をそのまま利用 できないため、別加工品となり製作コストが高くつくと共に、ローラ５を内輪９ で支持するのでローラ５と内輪９の間にクリープ現象が生じるという問題もある 。 However, since the ball bearing 6 having the flange 8 on the outer ring 7 cannot be used as a general-purpose ball bearing as it is, it is a separately processed product and the manufacturing cost is high, and since the roller 5 is supported by the inner ring 9, the roller 5 and the inner ring 9 are supported. There is also the problem that a creep phenomenon occurs between them.
【０００６】 そこでこの考案は、上記のような問題点を解決するため、ローラ支持の転がり 化を安価に実現することができると共に、クリープ現象の発生がないローラ支持 が行なえるフランジ付シェル形軸受を提供することを課題としている。In order to solve the above-mentioned problems, the present invention can realize the rolling of the roller support at a low cost, and at the same time, the flanged shell type bearing which can perform the roller support without creep phenomenon. The challenge is to provide.
【０００７】[0007]
上記のような課題を解決するため、この考案は、シェル形軸受における外輪の 外側に別体のフランジ部材を圧入固定した構成を採用したものである。 In order to solve the above problems, the present invention adopts a structure in which a separate flange member is press-fitted and fixed to the outer side of the outer ring in the shell type bearing.
【０００８】[0008]
シェル形軸受の外輪に圧入するフランジ部材はプレスで安価に製作でき、汎用 シェル形軸受との組合せによりローラ支持の転がり化が安価に実現できると共に 、シェル形軸受はころでローラを直接支持するので、ころとローラの間にクリー プ現象の発生がない。 The flange member that is press-fitted into the outer ring of the shell-type bearing can be manufactured at low cost by pressing, and by combining it with a general-purpose shell-type bearing, roller rolling can be realized at low cost, and the shell-type bearing directly supports the rollers with rollers. , No creep phenomenon between rollers and rollers.
【０００９】[0009]
以下、この考案の実施例を添付図面の図１乃至図３に基づいて説明する。 An embodiment of the present invention will be described below with reference to FIGS. 1 to 3 of the accompanying drawings.
【００１０】 図１と図２のように、シェル形軸受１１は、外輪１２の内部に組込んだ多数の 針状ころ１３を保持器１４によって一定の間隔に配置し、上記外輪１２の外側に 別体のフランジ部材１５を圧入固定した構造になっている。As shown in FIGS. 1 and 2, in the shell type bearing 11, a large number of needle rollers 13 incorporated in the outer ring 12 are arranged at regular intervals by a cage 14, and the outer ring 12 is covered with the needle rollers 13. It has a structure in which a separate flange member 15 is press-fitted and fixed.
【００１１】 図１に示すシェル形軸受１１の第１の例は、外輪１２の両端部に縁曲げ部１６ 、１６を設けたタイプであり、外輪１２の一方端部側に外嵌圧入するフランジ部 材１５は、プレス成形によって断面Ｌ字状に形成されている。A first example of the shell type bearing 11 shown in FIG. 1 is a type in which edge bending portions 16 and 16 are provided at both ends of the outer ring 12, and a flange that is press-fitted to one end of the outer ring 12 is fitted. The member 15 is formed into an L-shaped cross section by press molding.
【００１２】 このフランジ部材１５は特に熱処理する必要はなく、外輪１２に圧入した状態 で外輪１２とスポット溶接によって固定化される。The flange member 15 does not need to be heat-treated, and is fixed to the outer ring 12 by spot welding while being press-fitted into the outer ring 12.
【００１３】 この第１の例は、鋼板フレーム１７の孔１８に外輪１２を挿入し、フランジ部 材１５が鋼板フレーム１７の一面側に当接する状態で、針状ころ１３群によって ローラ１９を回動自在に支持する。In this first example, the outer ring 12 is inserted into the hole 18 of the steel plate frame 17, and the roller member 19 is rotated by the group of needle rollers 13 while the flange member 15 is in contact with one surface side of the steel plate frame 17. Support freely.
【００１４】 次に、図２に示すシェル形軸受１１の第２の例は、外輪１２の一方端部にのみ 縁曲げ部１６を設け、フランジ部材１５を圧入する側をストレート端部２０にす ると共に、外輪１２に圧入するフランジ部材１２の外側端部に外輪用の鍔２１を 一体に設けている。Next, in a second example of the shell type bearing 11 shown in FIG. 2, the edge bent portion 16 is provided only on one end portion of the outer ring 12, and the side on which the flange member 15 is press-fitted is the straight end portion 20. In addition, a flange 21 for the outer ring is integrally provided on the outer end of the flange member 12 that is press-fitted into the outer ring 12.
【００１５】 この第２の例では、外輪１２の両端における片方の縁曲げ部が省けるため構造 の簡素化が図れると共に、フランジ部材１５は、保持器１４が合成樹脂製の場合 、熱処理は不要であるが、保持器１４が金属製の場合、鍔２１の摩耗を避けるた め、軟窒化程度の熱処理を施すことが望ましい。In the second example, one edge bending portion at both ends of the outer ring 12 can be omitted, so that the structure can be simplified, and the flange member 15 does not require heat treatment when the cage 14 is made of synthetic resin. However, in the case where the cage 14 is made of metal, it is desirable to perform heat treatment such as soft nitriding in order to avoid wear of the collar 21.
【００１６】 次に、図３（Ａ）乃至（Ｃ）は、フランジ部材１５の圧入による外輪１２の内 径に変化が生じる場合に対処する手段をシェル形軸受の第２の例に適用した状態 を示している。Next, FIGS. 3A to 3C show a state in which means for coping with the case where the inner diameter of the outer ring 12 is changed by press fitting the flange member 15 is applied to the second example of the shell type bearing. Is shown.
【００１７】 即ち、外輪１２は、外側にフランジ部材１５を外嵌圧入することにより、圧入 部分の内径が縮径し、両側端部で内径の異いが出てくると、ローラ１９を直接転 走面とする針状ころ１３の円滑な転がりを妨げる要因となる。That is, in the outer ring 12, when the flange member 15 is externally fitted and press-fitted, the inner diameter of the press-fitted portion is reduced, and when the inner diameter becomes different at both end portions, the roller 19 is directly rolled. This becomes a factor that hinders the smooth rolling of the needle roller 13 as the running surface.
【００１８】 このため、外輪１２において、フランジ部材１５を圧入する部分の内周に、フ ランジ部材１５の圧入による内径の縮径分を見こしたぬすみ部分２２を設けてい る。For this reason, the outer ring 12 is provided with a recessed portion 22 on the inner periphery of the portion into which the flange member 15 is press-fitted, in which the reduced diameter of the inner diameter due to the press-fitting of the flange member 15 is found.
【００１９】 図３（Ａ）に示すぬすみ部分２２は、外輪１２の内周に設けた少量の段差によ って形成し、図３（Ｂ）はゆるやかなテーパをつけることによって形成している 。The recessed portion 22 shown in FIG. 3 (A) is formed by a small amount of step provided on the inner circumference of the outer ring 12, and FIG. 3 (B) is formed by making a gentle taper. ..
【００２０】 このように、外輪１２の内径でフランジ部材１５を圧入する部分に予めぬすみ 部分２２を設けておくと、図３（Ｃ）のように、外輪１２へフランジ部材１５を 圧入することによって外輪１２が縮径すると、ぬすみ部分２２が適切な転走面に 矯正され、針状ころ１３の円滑な転がりが得られることになる。As described above, when the recessed portion 22 is provided in advance in the portion where the flange member 15 is press-fitted with the inner diameter of the outer ring 12, the flange member 15 is press-fitted into the outer ring 12 as shown in FIG. 3C. When the outer ring 12 has a reduced diameter, the recessed portion 22 is corrected to an appropriate rolling surface, so that the needle roller 13 can be smoothly rolled.
【００２１】 この考案のフランジ付シェル形軸受は上記のような構成であり、鋼板フレーム １７の孔１８に外輪１２を挿入し、フランジ部材１５を鋼板フレーム１７の一面 側に当接させ、針状ころ１３群でローラ１９を回動自在に支持する。The flanged shell type bearing of the present invention is configured as described above, and the outer ring 12 is inserted into the hole 18 of the steel plate frame 17, and the flange member 15 is brought into contact with one surface side of the steel plate frame 17 to form a needle-like shape. The roller 19 is rotatably supported by the group of rollers 13.
【００２２】 シェル形軸受１１はフランジ部材１５が鋼板フレーム１７に当接することによ って軸方向に固定され、かつ、針状ころ１３群でローラ１９を転がり支持し、ロ ーラ１９の高速化を可能にしている。The shell type bearing 11 is axially fixed by the flange member 15 coming into contact with the steel plate frame 17, and the roller 19 is supported by the needle roller 13 group in a rolling manner. Is possible.
【００２３】 なお、シェル形軸受の取付けは、図示実施例では、鋼板フレーム１７に取付け たが、一般的なハウジング孔へ外輪を圧入する取付け時にはフランジ部材１５が 圧入時の位置決めとなる。この場合、外輪１２の内径にぬすみ部２２を設けなく ても、外輪１２は、ハウジング孔への圧入部分とフランジ部材１５が圧入された 部分が略同等に縮径することになり、針状ころの円滑な転がりが得られる。Although the shell type bearing is attached to the steel plate frame 17 in the illustrated embodiment, the flange member 15 is positioned during press-fitting when the outer ring is press-fitted into a general housing hole. In this case, even if the hollow portion 22 is not provided on the inner diameter of the outer ring 12, the outer ring 12 has a portion in which the press-fitted portion into the housing hole and the portion in which the flange member 15 is press-fitted have substantially the same diameter. You can get smooth rolling.
【００２４】 従って、シェル形軸受１１は事務機に限らず、種々の機器に使用することがで きる。Therefore, the shell type bearing 11 can be used not only for office machines but also for various devices.
【００２５】 また、シェル形軸受１１は、針状ころを用いたものを示したが、転動体にボー ルを用いたシェル形軸受を使用するようにしてもよい。Further, the shell type bearing 11 is shown as one using needle rollers, but a shell type bearing using balls as rolling elements may be used.
【００２６】[0026]
以上のように、この考案によると、シェル形軸受における外輪に別体のフラン ジ部材を圧入固定したので、ローラの転がり支持が汎用のシェル形軸受を用いて 行なえ、ローラの高速化が安価に実現できる。 As described above, according to the present invention, since the separate flange member is press-fitted and fixed to the outer ring of the shell type bearing, the rolling support of the roller can be performed by using the general shell type bearing, and the speeding up of the roller can be inexpensive. realizable.
【００２７】 また、シェル形軸受はローラを直接転走面とするため、内輪との間にクリープ 現象が発生するというようなことがなくなる。Further, in the shell type bearing, since the roller directly makes the rolling contact surface, the creep phenomenon with the inner ring does not occur.
