本発明は特許請求の範囲第１項の前提部分に記載のころ
がり軸受、特に玉軸受に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a rolling bearing, in particular a ball bearing, according to the preamble of claim 1.
上述のようなころがり軸受、特に玉軸受はドイツ連邦共

立てられなければならない。しかしその際困難が生ずる
。なぜならば内輪および外輪の端面は、大きな付加的出
費なしには、組立て力が玉を介して伝達されないほど正
確につくることができないからである。Rolling bearings, in particular ball bearings, of the type mentioned above are already known from German Utility Model No. 1913905. A radial deep groove ball bearing is shown here, which has a T-shaped cross-section retainer for sealing purposes on one side. The sealing effect is achieved by the legs of the lateral parts projecting into the edge recesses of both inner and outer rings. However, there are problems when assembling such bearings. For reasons of simplicity, the entire bearing with its inner and outer rings must therefore be assembled at the same time with a reinforced periphery. However, difficulties arise in doing so. This is because the end faces of the inner and outer rings cannot be made so precisely that the assembly forces are not transmitted via the balls without great additional expenditure.
したがって通常の軸受の場合には、組立ての際に玉の損
傷が起こり、そのことが早期の軸受故障に至らせるとい
う大きな危険が生ずる。With conventional bearings, there is therefore a great risk that the balls will be damaged during assembly, leading to premature bearing failure.
本発明の課題は、特許請求の範囲第１項の前提部分に記
載の軸受を改良して、軸上へおよびハウジング内への軸
受けの押込みの際の内輪および外輪の端面の有り得る不
精確が玉の損傷に至らせずかつその際同時に密Ｅ効果が
維持されかつ付加的に腐食に対する内外輪の端面の保護
もできるようにすることである。It is an object of the invention to improve the bearing according to the preamble of claim 1 in such a way that possible inaccuracies in the end faces of the inner and outer rings when pushing the bearing onto the shaft and into the housing are eliminated. The object of the present invention is to prevent damage to the inner and outer rings, while at the same time maintaining the high-E effect, and additionally to protect the end faces of the inner and outer rings against corrosion.
この課題の解決策は特許請求の範囲第１項の特徴部分に
明示されている。特許請求の範囲第２項および第３項は
特別の構成を含んでいる。A solution to this problem is specified in the characterizing part of claim 1. Claims 2 and 3 contain special features.
Ｔ字状保持器の横部分が内外輪の端面より全部または一
部突出し、脚部が比較的大きい面を持つ各内外輪に対向
していることによって、非常に大きい組立て力を加える
ことができる。組立て力は横部分の脚部を介して両方の
内外輪へ伝達される。内外輪の端面の不精確は、弾性プ
ラスチック製の保持器が使用されることによって除去さ
れる。大きい不精確の場合は玉は荷重をかけられない。A very large assembly force can be applied because the lateral portion of the T-shaped retainer protrudes in whole or in part from the end faces of the inner and outer rings, and the legs face the inner and outer rings, each having a relatively large surface. . The assembly forces are transmitted to both inner and outer rings via the legs of the lateral parts. Inaccuracies in the end faces of the inner and outer races are eliminated by the use of resilient plastic cages. In the case of large inaccuracies, the ball cannot be loaded.
なぜならば脚部と内外輪との間の遊隙は転動体と保持器
ポケットの底部との間の軸線方向遊隙より常に小さいか
らである。This is because the play between the legs and the inner and outer rings is always smaller than the axial play between the rolling elements and the bottom of the cage pocket.
玉はポケット内において遊隙を持っているから、作動位
置においてＴ字状保持器の脚部と内外輪の端面との間に
小さい間隙が生ずる。それによって両方の内外輪へしば
しば望ましいラビリンス密封が生ずる。Since the balls have play in the pocket, a small gap is created between the legs of the T-shaped retainer and the end faces of the inner and outer races in the operating position. This results in an often desirable labyrinth seal to both the inner and outer races.
好ましい構成によれば、組立て力は保持器の横部分にあ
る隆起を介して加えられる。それによって力の経過はさ
らに改善される。すなわち横部分の脚部は荷重に応じて
さまざまにそり返ることができる。According to a preferred configuration, the assembly force is applied via ridges on the lateral parts of the retainer. The force course is thereby further improved. That is, the legs of the lateral parts can bend in various ways depending on the load.
別の好ましい構成により横部分の脚部が外輪の局面およ
び内輪の孔面まで延びている場合は、密封効果をさらに
高めることができる。それによりハウジングおよび軸と
共に、さらに有利な屈曲したラビリンス間隙および内外
輪端面の保護が得られる。The sealing effect can be further increased if, in a further preferred embodiment, the legs of the lateral parts extend to the curved surface of the outer ring and to the bore surface of the inner ring. This provides further advantageous protection of the housing and the shaft as well as the curved labyrinth gap and the end faces of the inner and outer rings.
本発明を図面により詳細に説明する。図面は櫛形保持器
を持つラジアル深溝玉軸受の部分断面を示している。The present invention will be explained in detail with reference to the drawings. The drawing shows a partial cross-section of a radial deep groove ball bearing with a comb cage.

状保持器４から成る。作動位置において保持器４の横部
分５の脚部５′および５＃は内外輪ｌおよび２の端面に
小さい遊隙６を持って対向している。According to the drawings, the bearing consists of an inner ring 11, an outer ring 2, a set of five 3 and a T-shaped retainer 4. In the operating position, the legs 5' and 5# of the lateral part 5 of the cage 4 face the end faces of the inner and outer rings 1 and 2 with a small clearance 6.

償される。保持器４がプラスチックからできている場合
は、この効果はさらに高められる。Furthermore, the lateral part 5 is provided with an annular bulge 8 . When an assembly force 9 is applied to this annular bulge, the play 6 is first nullified. This is because the play 7 between the balls 3 and the bottom 4' of the retainer pocket is greater than the play 6. Ball 3 is therefore never subjected to assembly forces. The assembly forces are transmitted directly from the legs 5' and 5' to the inner and outer fi+ and 2 as desired. Inaccuracies are compensated for by the elasticity of the legs 5' or 5'. This effect is further enhanced if the cage 4 is made of plastic.
