〔発明の利用分野〕
本発明は軸受装置に係り、例えば配電器の軸受装置に有
効である。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a bearing device, and is effective for example in a bearing device for a power distributor.
従来、特開５５−１３９９７４号公報のようなものでベ
アリングの組付けは、予めシャフトにベアリングを圧入
しておき、次にベアリングの外輪部をハウジングに固定
する方式と、予めハウジングに装着し、次にシャフトに
圧入する方式とがある。Conventionally, there are two methods for assembling a bearing, such as those disclosed in Japanese Patent Application Laid-Open No. 55-139974, in which the bearing is press-fitted onto the shaft in advance, and then the outer ring of the bearing is fixed to the housing. The next method is to press fit into the shaft.
しかし前者は、シャフトにウェイト取付台が一体になっ
ており、通常、ウェイトなどの部品が装着しているため
、ベアリング抑え板を介して一部の空隙よりネジを通す
が、加締工具を挿入して固定するしかなく、生産性に問
題があった。However, with the former, the weight mounting base is integrated into the shaft, and parts such as weights are usually attached to it, so the screw is passed through a part of the gap through the bearing holding plate, but the tightening tool is inserted. There was a problem with productivity.
一方、後者は、シャフトを圧入荷重が比較的大きく、ベ
アリングの外輪で該荷重を受けるためボール転走面に圧
痕をつける可能性あり、実用されなかった。On the other hand, the latter has not been put to practical use because the shaft is press-fitted with a relatively large load and the outer ring of the bearing receives the load, which may cause impressions on the ball rolling surface.
一方、いずれの場合も、シャフトのベアリング嵌合部は
ベアリングをシャフトに圧入する関係上。On the other hand, in either case, the bearing fitting part of the shaft is because the bearing is press-fitted into the shaft.
含油メタルの嵌合部より径を大きくする必要があるため
、シャフトが段付になり研磨加工も生産性に問題があっ
た。Since the diameter needs to be larger than the fitting part of the oil-impregnated metal, the shaft becomes stepped and there are problems with productivity during polishing.
本発明はかかる欠点を除去した軸受装置を提供するもの
である。The present invention provides a bearing device that eliminates such drawbacks.
本発明はシャフトの圧入荷重を必要以上に発生させない
よう、ベアリングの内輪とシャフトの間で局部的に金属
の塑性変形をさせるものである。The present invention locally causes plastic deformation of the metal between the inner ring of the bearing and the shaft so as not to generate an unnecessarily high press-fitting load on the shaft.
次に、本発明の実施例を第１〜第４図について説明する
。Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 4.
１は配電器のハウジングで、ベアリング２．オイルシー
ル３．含油メタル４を夫々、収納している。５はシャフ
トで、ウェイト７を懸架しているウェイト取付台６を一
体にしている。８はワッシャ、９はカップリングである
。以上は公知の構造である。1 is the housing of the power distributor, bearing 2. Oil seal 3. Each oil-impregnated metal 4 is stored therein. Reference numeral 5 denotes a shaft, which integrates a weight mounting base 6 on which a weight 7 is suspended. 8 is a washer and 9 is a coupling. The above is a known structure.
次に本発明の要部について説明する。第２図に示す如く
ベアリング２の外輪はハウジング１の金属を塑性流動さ

でベアリング２の嵌合部に設けである。次に第２図に示
す状態でＰ−Ｑ方向に荷重を加えシャフト５をベアリン
グ２の内輪に圧入する。Next, the main parts of the present invention will be explained. As shown in FIG. 2, the outer ring of the bearing 2 is fixed by causing the metal of the housing 1 to plastically flow, and by causing the flesh to plastically flow and bite into the plurality of V grooves 10. Reference numeral 11 denotes a spline having a plurality of projections and depressions 15 and 16 formed by polishing the shaft 5 and then performing plastic processing, and is provided at the fitting portion of the bearing 2. Next, in the state shown in FIG. 2, a load is applied in the P-Q direction to press fit the shaft 5 into the inner ring of the bearing 2.
本発明は上述の如くシャフト５を全周圧入するのではな
く、部分的に圧入するため、圧入荷重は少なくなり、ベ
アリング２のボール部に圧痕が発生ずる許容荷重以下で
あり、且つ核部の緊縛力はシャフト５などの振動に充分
耐えるものである。In the present invention, as described above, the shaft 5 is not press-fitted all around, but is partially press-fitted, so the press-fitting load is small and is less than the allowable load that would cause an indentation on the ball part of the bearing 2, and the core part The binding force is sufficient to withstand vibrations of the shaft 5 and the like.
また、第３図、第４図のようにスプラインはシャフト５
の両側から金具１７で押圧して形成されるためシャフト
５に設けたスプライン１１は凸部１５と凹部１６が形成
され、圧入する時凸部１５により移動する肉は凹部１６
へ流れるため圧入該重は小さくてすむものである。Also, as shown in Figures 3 and 4, the spline is attached to the shaft 5.
Since the spline 11 provided on the shaft 5 is formed by pressing with metal fittings 17 from both sides, a convex portion 15 and a concave portion 16 are formed, and the flesh that moves due to the convex portion 15 when press-fitting is formed in the concave portion 16.
The weight of press-fitting can be small because the flow flows into the air.
以上の通り、本発明は小さい圧入荷重で確実な固定が得
られるものである。As described above, the present invention provides reliable fixation with a small press-fitting load.
