【発明の詳細な説明】
〔産業上の利用分野〕
この発明は回転体を有する電動機等に広く使用されるこ
ろがり軸受に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rolling bearing widely used in electric motors having a rotating body.
ころがり軸受は、一般に内輪を回転軸に強く、又外輸を
ハウジングに緩く嵌合させ使用される。Rolling bearings are generally used with the inner ring tightly fitted around the rotating shaft and the outer ring loosely fitted into the housing.
しかして外輪とハウジングとの間にクリープを生じ易い
。このクリープを防止するために一般に第５図による軸
受構造が用いられる。Creep is therefore likely to occur between the outer ring and the housing. To prevent this creep, a bearing structure according to FIG. 5 is generally used.

ーである。In the figure, 1 is the shaft of the motor, 2 is the housing 3 in the center.
Brakent has the following. Reference numeral 4 designates a ball bearing in which an internal shaft 41 is fitted into the shaft 1 and an external shaft 42 is loosely fitted into the housing 3, and 5 is an inner end force bar fixed to the bracket 2 by bolts 6.

。Thus, the outer ring 42 of the bearing 4 is clamped and fixed between the outer end cover portion 2a of the bracket 2 and the inner end force bar 5 by screwing the bolt 6 into the inner end cover 5. Therefore, the occurrence of the creep is prevented.
ところで従来の玉軸受４は、クリープを防止するために
、内エンドカバー５を必要とする軸受構造となり、軸受
構造の構成が複雑で組立が煩雑となる欠点がある。However, the conventional ball bearing 4 has a bearing structure that requires an inner end cover 5 to prevent creep, and has the drawback that the structure of the bearing structure is complicated and assembly is complicated.
この発明はクリープの防止が可能でかつ簡単な軸受構造
を採用できるころがり軸受を提供することを目的とする

〔課題を解決するための手段〕
上記目的を達戒するために、この発明によれば、ころが
り軸受の外輪の端面に凹部を形或するものとする。The purpose of this invention is to provide a rolling bearing that can prevent creep and employ a simple bearing structure. [Means for Solving the Problems] In order to achieve the above object, according to the present invention, a recess is formed in the end face of the outer ring of the rolling bearing.
ブラケットに回り止めを設け、この回り止めの先端を前
記ころがり軸受の凹所に挿入することにより外輪の回転
が阻止される．即ちクリープを防止することができる。Rotation of the outer ring is prevented by providing a detent on the bracket and inserting the tip of the detent into the recess of the rolling bearing. That is, creep can be prevented.
第１図及び第２図はこの発明の実施例を示すもので、第
５図と共通あるいは同一の部分は同じ符号で示す。1 and 2 show an embodiment of the present invention, and parts common or identical to those in FIG. 5 are designated by the same reference numerals.
第１図及び第２図において、玉軸受４の外輪４２には、
その端面に凹所としてなる錐穴状の丸穴４３が形成され
る。In FIGS. 1 and 2, the outer ring 42 of the ball bearing 4 includes:
A cone-shaped round hole 43 serving as a recess is formed in the end face.
しかして外輪４２のクリープを防止するには、ブラケッ

よい。従って従来の軸受横造における内エンドカバー（
第５図の５）やボルト（第５図の６）を必要とせず、か
つブラケ・７ト２に前記ボルト用のボルト孔が不要とな
るので、軸受構造が簡素化され、又組立も極めて容易と
なる。In order to prevent the outer ring 42 from creeping, a pin hole may be made in the outer end cover portion 2a of the bracket 2, and the tip of the pin 7 fitted into the pin hole may be inserted into the round hole 43. Therefore, the inner end cover (
Since 5) in Figure 5 and bolts (6 in Figure 5) are not required, and bolt holes for the bolts are not required in bracket 7, the bearing structure is simplified and assembly is extremely easy. It becomes easier.
第３図は軸受構造に対する第２図の実施例の変形例を示

端面上に設けたピン穴と外輪４２の九穴４３との間にか
すがい状の固定ビン８が設けられる。この固定ピン８に
よって外輪４２のクリープが防止され、かつ上述の実施
例と同様の効果が得られる。FIG. 3 shows a modification of the embodiment of FIG. 2 with respect to the bearing structure, in which creep is prevented from the inner end surface side of the ball bearing 4. In FIG. In this case, a screw-shaped fixing pin 8 is provided between the pin hole provided on the inner end surface of the housing 3 of the bracket 2 and the nine holes 43 of the outer ring 42. This fixing pin 8 prevents the outer ring 42 from creeping, and provides the same effect as the above embodiment.

面や外端面に接触させる方法が用いられている。時には
接触不良を生じ計測が確実に行われないことがあった。FIG. 4 shows an embodiment of the use of the nine holes 43 provided in the foreign material 42 for purposes other than creep prevention. Conventionally, when measuring the outer ring temperature, a method has been used in which a temperature sensing part provided at the tip of a lead wire led to a thermometer is brought into contact with the outer peripheral surface or outer end surface of the outer ring through a hole drilled in a bracket. Occasionally, poor contact occurred and measurements could not be performed reliably.
この実施例では前記リード線９先端の感温部１０を丸穴
４３に埋込むことによって外輪４２の温度を確実に計測
することができる。In this embodiment, the temperature of the outer ring 42 can be reliably measured by embedding the temperature sensing portion 10 at the tip of the lead wire 9 in the round hole 43.
この発明によれば、ころがり軸受の外輪の端面に凹部を
形成したので、外輪にクリープを発生させることがなく
、かつその軸受構造を従来に比べ格段に簡単な構成とす
ることができる。更に外輪温度の計測において確実な温
度計測が行える。According to this invention, since the concave portion is formed in the end face of the outer ring of the rolling bearing, creep does not occur in the outer ring, and the bearing structure can be made much simpler than the conventional one. Furthermore, reliable temperature measurement can be performed when measuring the temperature of the outer ring.
