Abstract

A bearing box having an attached cover for protecting the box from dust or the like. Whereas the conventional cover is clamped by bolts or the like, the bearing box according to this invention requires no machining work other than provision of a spigot joint. There are provided clamping brackets (4) to be attached to the seat, groove or projection or the like formed on the cover (2) and formed with a pawl-engaging seat (5a). The brackets (4) are axially bridged across the bearing box in such a manner that the brackets (4) are engaged with the pawl-engaging seats formed on the bearing box and the pawl-engaging seats formed on the cover (2), whereby the cover (2) is attached to both or one face of the bearing box in axial direction under pressure. It is an object of this bearing box to reduce the production cost of a bearing unit and to provide an easily-detachable cover for check and maintenance. Thus, this bearing box may be used for various bearing units.

Most of the methods use screws such as ruts. The bolting by bolts etc. has the advantage that the cover can be actually attached to the bearing box, and in the production of the bearing box, several screws are used in the drilling process and during assembly. With the addition of bolting work, the cost rises by this work. In addition, the user needs to attach and detach the cover for maintenance and inspection when using it, and it is necessary to release the bolts and tighten the bolts. It takes time and effort. In addition, the vault

そ こ で、 ネ ジ類を用い て締着す る 方法以外 の軸受箱に カバ ー を取着す る 方法 が求め られ る と こ ろ であ る が、 こ れま でに具体的な提案が少な い上 、 種 々 の取着方法が考 え られる が、 それぞれに 欠点を有 し広 く 実用化 に至って い な い のが実状 であ る 。 以下に こ れ ら に ついて考察す る。  Therefore, there is a need for a method of attaching the cover to the bearing box other than the method of fastening with screws, but specific proposals have been made so far. Although there are few methods of attachment, various attachment methods are conceivable, but each has its own drawbacks and has not yet been put to practical use. These are discussed below.
た と えば、 カ バ -全体を軸受箱に螺合す る 方法があ る 。 これは、 カ バ - の 外周 およ び軸受箱側に螺刻す る 必要 があ り 、 使用で き る カ バ — は円形に限 られ、 しか も 螺刻 等の加工工程が加わ る ため コ ス ト 高を 招 ぐ 。 さ らに使用 時にその振動に よ る螺合の ゆ る みを生 じさせない よ う に 何ん らかの手当 が必要 と な る 。  For example, there is a method of screwing the entire cover into a bearing housing. This requires screwing on the outer periphery of the cover and on the bearing housing side, and the usable cover is limited to a circular shape, and additional processing steps such as screwing are added. Invites a high price. In addition, some care must be taken to prevent loosening due to the vibration during use.

And high cost. Further, this method has a drawback that the dust holding effect is small because the holding power of the cover is weak.

This is enough to provide a part to mark on the cover mounting surface of ^ receiver, but it is good to just fix the magnet to the fa receiving box or cover. Although it is easy to use, there is an advantage, but if the magnet attracting force is used so that the power bar can be easily attached / detached,

This is a bearing box to which a cover is attached so as to be pressed against the bent part of. In Japanese Utility Model Application Publication No. 52-160734-5, for example, a frustum-shaped frustum-shaped cover made of steel plate is inserted into a portion of the bearing box where a cross-sectional waveform is to be formed, and the cover itself is inserted. We have proposed a bearing box with a dust-proof cover that uses the elasticity of the cover to fix the projection and the part to be marked on the cover.
いずれ も 、 製作費 の低減 、 カ バ - の着脱の容易 さ と防 塵能力の向 上を 目 的 と する も ので あ る 。  In any case, the aim is to reduce the manufacturing cost, to easily attach and detach the cover, and to improve the dustproofing ability.

Then, the parts 6 to be marked are provided on both sides of the cover-mounting of the bearing box 1, and the fitting of the bearing box 1 and the cover-2 is confirmed. This is conventional! ) This is the method used o

Each of the claws is fitted into the catch receiving seat 5, and the pair of covers-2 is pressed against the respective marking portions 6 toward the center of the bearing box 1 by utilizing the elasticity of the stopper 4. Then, the attachment of the dustproof cover -2 to the bearing housing 1 is completed.

Make sure that the fitting does not come off even if it is pulled, and the size of the fitting is 4 as shown in Fig. 1. Any size is acceptable in the circumferential direction. In this case, two fasteners 4 are used. However, according to the shape of the cover 2 (for example, a polygonal shape), or to increase or decrease the press-fitting force of the cover 2 to the marking portion 6. Any number of fasteners 4 can be used accordingly. In order to open the stopper 4, it is possible to release the stopper 4 by removing the fitting of the pawl 4 from the receiving seat. '

The perspective view shown in FIG. 3 shows a case in which a projection-shaped pawl receiving seat 5a is provided over the entire outer periphery of the conical-shaped cover-2 bottom outer surface, and this pawl receiving seat 5a is easily understood. It's exaggerated to do it.

However, part of the cut-out portion 5b is used as the notch 5b, and the stopper 4 is pushed in and inserted without spreading, and a slide is formed on the pawl receiving seat 5a. Attach BA-2. In this case as well, the cover 2 should be formed so as to abut the stamped portion of the bearing housing 1. Note that the notch 5b in Fig. 3 is notched with a slope so that it is easy to insert the stopper. The two stoppers 4 are turned around. The case where the cover 2 is attached is shown, but the position, shape, and projection of the notch 5b are not shown.

As shown in the perspective view of the pillow unit shown in Fig. 4, the L-shaped groove 5c can have any length in the circumferential direction. A notch 5b is provided in the hole, and the cover 2 can be attached by fitting an arbitrary number of the fasteners 4.
以上は ピ ロ 一 形ュ ニ ッ 卜 につい て説明 した が、 各種形 伏の フ ラ ン ジ形 ュニ ッ ト に も こ の発明 を適用す る .こ と が で き る。 その一例を第 5 図の斜視図に示す。  Although the above description has been made with respect to a pillow-shaped unit, the present invention can also be applied to a flange-shaped unit having various shapes. An example is shown in the perspective view of FIG.
すな わ ち 、 上述 した突起伏つめ受け座 5 aを有す る カ バ - 2 を 、 フ ラ ン ジ形軸受箱 7 の印 ろ う 部に 当接さ せ取着 す る 場合 、 軸受箱 7 の一部 に止め金具 4 の一方 のつめが 嵌入 し得 る よ う 欠切部 7 aを設け、 カ ノく' — 2 と軸受箱 7 の それぞれ めつめ受け座 5 a , 7 aに止 め金具 4 を嵌入する 。 こ こ で軸受箱 7 のつめ受け座を欠切部 7 aと したが、 第 1 ^で示 し た ^設す る つめ受け座 5 を は じめ 、 フ ラ ン ジ形 ュ ニ ッ 卜 の形状 に合せた任意数のつめ受け座 と す る こ と がで き る 。 な お 、 ピ ロ 一 形ュニ ッ 卜 に おい て も 、 軸受箱 の ¾ ^ に こ の欠 切部 7 aと 同様の つめ受け座を設けて 、 前 ¾ した軸受箱を跨 ぐ止め金具 と 併用 し カ バ 一 を取着す る こ と も でき る 。 In other words, when the cover 2 having the protruding tabs 5a described above is mounted on the flange-shaped bearing box 7 by abutting the cover-2, the bearing box is required. 7 is provided with a notch 7a so that one of the claws 4 can be fitted into it, and the knuckle '— 2 and the bearing box 7 are respectively fastened to the nail receiving seats 5a and 7a. Insert the metal fitting 4. In this case, the nail receiving seat of the bearing housing 7 is formed as the notch 7a, but the nail receiving seat 5 shown in the first ^ is provided, and the flange receiving unit 5 is formed of the flange type unit. Any number of pawl seats can be made according to the shape. In the case of a pillow-shaped unit, a pawl receiving seat similar to the notch 7a is provided at the ¾ ^ of the bearing box, and a stopper for straddling the above-mentioned bearing box is provided. Attach cover together You can do that too.
