【発明の詳細な説明】
本発明は軸受として使用しているボールベアリンク、ニ
ードルベアリングなどのベアリングの固定構造に関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fixing structure for a bearing such as a ball bearing link or a needle bearing used as a bearing.
従来のベアリングの固定構造としては、圧入固定、接着
固定、ベアリング側面からの挾み込み固定によるもの等
があった。Conventional bearing fixing structures include press-fit fixing, adhesive fixing, and fixing by inserting from the side of the bearing.
出入固定においてはベアリング外径寸法と、圧入側穴径
寸法のバラツキによシ、圧入不十分及びベアリング回転
不良が発生した。接着固定においては、乾燥迄に時間を
要し、又、ゴミ、油等による固定力の変動及び余分の接
着剤による二次的事故の発生があった。When fixing the bearing in and out, insufficient press-fitting and poor bearing rotation occurred due to variations in the outer diameter of the bearing and the diameter of the press-fit hole. When fixing with adhesive, it takes time to dry, and the fixing force fluctuates due to dust, oil, etc., and secondary accidents occur due to excess adhesive.
ベアリング側面からの挾み込み固定においては、ベアリ
ングの同心度管理が必要であシ、又、固定用の部品の追
加等コスト面にも不利な点が多かった。When fixing the bearing by inserting it from the side, it is necessary to control the concentricity of the bearing, and there are many disadvantages in terms of cost, such as the addition of fixing parts.
本発明の目的は、作業性向上やベアリング回転特性維持
が確保できるベアリングの固定構造を提供することにあ
る。An object of the present invention is to provide a bearing fixing structure that can improve workability and maintain bearing rotational characteristics.
本発明のベアリングの固定構造は、外周にナールを有す

に対して同心で回転する内輪を有するベアリングと、前
記ベアリングを前記ナールを介して出入固定する穴を有
する被固定物とを具備することを特徴とする。The bearing fixing structure of the present invention includes an outer ring having a knurl on the outer periphery, a rolling part, a bearing having an inner ring that rotates concentrically with respect to the outer ring via the rolling part, and the bearing being fixed in and out through the knurl. and an object to be fixed having a hole.
本発明の実施例を図面を診照して説明する。 Embodiments of the present invention will be described with reference to the drawings.

リングを示す。FIG. 1 shows a bearing in which a straight knurl 14 is attached to the outer circumference of an outer ring 13. A rolling part 12 is provided between the inner ring 11 and the outer ring 13. FIG. 2 shows a bearing in which a spiral knurl 24 is attached to the outer periphery of an outer ring 23. FIG. 3 shows a bearing in which diamond knurls 34 are attached to the outer periphery of an outer ring 33.
なお、各図に共通な要素として、出入ガイド用のテーパ
ーを付けである。A common element in each figure is a taper for guiding entry and exit.
第４図はワンウェイクラッチベアリングのロック方向を

トナール４４を付けである。FIG. 4 shows a bearing with a taper 45 for guiding in and out only on one side in order to clarify the locking direction of the one-way clutch bearing. Further, a straight knurl 44 is attached to the outer periphery of the outer ring 43.
第５図は本発明の実施例を示し、１は第４図に示したベ
アリングであシ、５はこのベアリング１を圧入固定した
。動力伝達用の歯車を示す。FIG. 5 shows an embodiment of the present invention, in which 1 is the bearing shown in FIG. 4, and 5 is the bearing 1 which is press-fitted and fixed. Shows gears for power transmission.
ベアリング外輪の外周にナールを付け、圧入対象物の穴
部に圧入することによシ、ナール部が穴部のかべに食込
み、抜は防止や回転防止となり、各部の寸法精度がハメ
アイ寸法と比較し公差範囲が広くとれる。By attaching a knurl to the outer periphery of the outer ring of the bearing and press-fitting it into the hole of the object to be press-fitted, the knurl bites into the wall of the hole, preventing pull-out and rotation, and the dimensional accuracy of each part can be compared with the fitting dimensions. This allows for a wide tolerance range.
又、出入の際、従来はベアリング全体に圧縮応力がかが
シ、ベアリング回転不良が発生していたが、ベアリング
外輪の外周にナールを付けることによシ、ナール部が出
入対象物の穴部に食込み固定する為、ベアリングにかか
る圧縮応力が比較的小さく、ベアリング回転不良が防止
出来る。In addition, when moving in and out, compressive stress was applied to the entire bearing, which caused bearing rotation failure, but by adding a knurl to the outer periphery of the outer ring of the bearing, the knurled part can be easily attached to the hole of the object to be moved in and out. Because it bites into the bearing and fixes it, the compressive stress applied to the bearing is relatively small, preventing bearing rotation failure.
本発明は以上説明したように、ベアリング外輪の外周に
ナール加工を実施することによシ、圧入後の抜は防止及
び回転止めが容易に得られ、寸法精度も比較的範囲が広
く得られ、量産性向上が計れる。As explained above, by knurling the outer periphery of the outer ring of the bearing, the present invention can easily prevent removal after press-fitting and stop rotation, and can also achieve a relatively wide range of dimensional accuracy. Mass productivity can be improved.
