込むようにしたアンギュラ玉軸受として、いわゆる外輪
分離型のものが用いられる。Incorporate the required number of balls held by the retainer into the rolling grooves of the inner ring, first integrate the inner ring, balls and the retainer around the shaft first, and then install the outer ring later. As such an angular ball bearing, a so-called outer ring separated type is used.
外輪分離型のアンギュラ玉軸受においては、外輪を分

込んで、内輪35に組み付けるようになっていた。In an outer ring-separated angular contact ball bearing, a retainer for holding the inner ring and the ball in an integrated state with the outer ring separated is used, but such a retainer is conventionally used as shown in FIG. Provided on the peripheral surface of the resin ring 31 are a plurality of ball storage pockets 32 opening on the inner diameter side and the outer diameter side,
A ball 34 is inserted into each of the pockets 32 from the outer diameter side opening 33 and assembled to the inner ring 35.

点があった。However, in such an angular ball bearing, in order to reliably limit the amount of movement of the ball 34 in the outer diameter direction, the strength of the outer diameter side opening 33 of the pocket 32 is increased to increase the strength of the ball.
It is necessary to increase the holding force to the 34, but this increases the amount of insertion when inserting the ball from the outer diameter side of the cage, and there is a disadvantage that the workability in assembling the bearing is deteriorated. .
しかし、ボールのかち込みを容易にするために、ポケ
ットの外径側開口部33の形状を大きくすると、ボールの
動き量が大きくなって各ボールの内接円径が大きくな

る。However, if the shape of the opening 33 on the outer diameter side of the pocket is increased to facilitate the insertion of the ball, the amount of movement of the ball is increased, and the inscribed circle diameter of each ball is increased. There is a problem that integration cannot be reliably performed.
そこで、この考案は、ボールのかち込み量に関係なく

とする可撓性を付与した構成としたものである。In order to solve the above-mentioned problem, the present invention incorporates a required number of balls held by a ring-shaped synthetic resin retainer into a rolling groove of the inner ring, and integrates the inner ring, the ball and the retainer. In an outer ring separated type angular contact ball bearing in which an outer ring is detachably fitted to a circumscribed circle diameter of the ball, a required number of pockets provided in the retainer are formed to have a required number of pocket inner diameter side openings sized to allow the ball to be inserted. At the same time, the outer diameter side opening is formed to a size that prevents the ball from coming out,
The inscribed circle diameter of each ball in the state of being stored in each of the pockets is set smaller than the outer diameter surface of the inner ring, and the inner ring can be pressed into the inside of each ball at the outer diameter side opening. This is a configuration in which flexibility is provided.
なお、上記の構成において、ポケットの内径側周面に

Of the inner ring, the retainer and the ball can be reliably integrated.
第１図及び第２図は、実施例のアンギュラ玉軸受の保
持器を示しており、この保持器１は、合成樹脂から成る
リング２の周面に、円周方向に一定間隔で複数のボール
収納用ポケット３を設けて成っている。1 and 2 show a retainer for an angular contact ball bearing according to an embodiment. The retainer 1 is provided with a plurality of balls at a constant interval in a circumferential direction on a peripheral surface of a ring 2 made of a synthetic resin. A storage pocket 3 is provided.
上記各ポケット３は、内周面４がボール９の形状に対
応した球面になっており、その内径側と外径側の両方向
に開口部５、６を有している。Each of the pockets 3 has a spherical inner surface 4 corresponding to the shape of the ball 9, and has openings 5 and 6 in both directions on the inner diameter side and the outer diameter side.

えるようになっている。The distance A from the small-diameter end 7 of the cage 1 to the inclined portion on the inner diameter side is the distance A 'of the conventional cage 30 shown in FIG.
3 (A <A '). As a result, as shown in FIGS. 3 and 10, the shape of the inner diameter side opening 5 of the pocket 3 becomes larger than that of the conventional retainer 30, The insertion of the ball 9 from the opening 5 can be performed with a small pushing force.
なお、このようなボールのかち込み量を小さくする方
法としては、保持器１の内径d1を大きくする方法を採用
することもできる。As a method of reducing the value inclusive of such balls, it is also possible to employ a method of increasing the inner diameter d 1 of the cage 1.
一方、各ポケット３の外径側開口部６は、ボール９の

されている。On the other hand, the outer diameter side opening 6 of each pocket 3 is formed in a size that does not allow the ball 9 to come out, and as shown in FIG. The inscribed circle diameter d of each ball stored in the pocket 3
Is set to be smaller than the diameter D of the outer diameter surface 12 of the inner ring 10.
また、外径側開口部６には、各ポケットにボール９を
収納した状態で、その各ボールの内側に内輪10の外径面
12を圧入したとき、各ボール９を拡径させて内輪10の圧
入を許容する可撓性がもたされている。Further, in the outer diameter side opening 6, the ball 9 is stored in each pocket, and the outer diameter surface of the inner ring 10 is provided inside each ball.
When the ball 12 is press-fitted, each ball 9 is expanded to allow the inner ring 10 to be press-fitted.
なお、上記の外径開口部６にボール９の抜け出しを阻
止できるだけの強度をもたせるには、保持器１の外径D1

なり、ボール９に対する大きな保持力を得ることができ
る。In order to provide the outer diameter opening 6 with sufficient strength to prevent the ball 9 from coming off, the outer diameter D 1 of the cage 1 is required.
And a method of increasing the distance B from the large-diameter end 8 of the retainer to the outer-diameter inclined portion. According to this method, the thickness of the outer diameter side opening 6 is increased, and a large holding force for the ball 9 can be obtained.
上記のごとき保持器１を用いてアンギュラ玉軸受を組
み立てるには、先ず、保持器１の小径側端部７を下側に
向けた状態で、第４図に示すように内径側開口部５から
ボール９を各ポケット３内に挿入し、その各ボール９の
内側に、内輪10を外径面12側から押し込んで組み付け
る。In order to assemble the angular contact ball bearing using the cage 1 as described above, first, with the small-diameter side end 7 of the cage 1 turned downward, as shown in FIG. The ball 9 is inserted into each of the pockets 3, and the inner ring 10 is pushed into the inside of each of the balls 9 from the outer diameter surface 12 side and assembled.
この状態では、各ボール９が内輪10のボール転走溝13
に入り込むと共に、その内接円形ｄが内輪の外径面12の
径Ｄより小さくなるため、保持器１とボール９は内輪10
から分離せず、３者が一体の状態で保持される。In this state, each ball 9 is in the ball rolling groove 13 of the inner ring 10.
As the inscribed circle d becomes smaller than the diameter D of the outer diameter surface 12 of the inner ring, the cage 1 and the ball 9
And the three members are held in an integrated state.
このため、次に、第５図に示すように保持器１の外径
