Description
【０００１】[0001]
この考案は高速回転に使用される合成樹脂製保持器に関するものである。 The present invention relates to a synthetic resin cage used for high-speed rotation.
【０００２】[0002]
合成樹脂から成る保持器として、図６に示したものが従来から知られている。 この保持器は、環状の保持器本体３０の一側面に対向一対の爪３１ａ、３１ｂを 周方向に等間隔に形成し、その一対の爪３１ａ、３１ｂ間にボール保持用ポケッ ト３２を設けている。 As a cage made of synthetic resin, the cage shown in FIG. 6 is conventionally known. In this cage, a pair of opposed claws 31a and 31b are formed on one side surface of an annular cage body 30 at equal intervals in the circumferential direction, and a ball holding pocket 32 is provided between the pair of claws 31a and 31b. There is.
【０００３】 上記保持器は、図７の鎖線で示すように、爪形成側の側面を先にして外輪３３ と内輪３４間に挿入し、両輪３３、３４間に予め組込まれた複数のボール３６の それぞれを対向一対の爪３１ａ、３１ｂの変形によってポケット３２内に挿入さ せるようにしている。As shown by the chain line in FIG. 7, the retainer is inserted between the outer ring 33 and the inner ring 34 with the side surface on the claw forming side first, and a plurality of balls 36 previously assembled between the both wheels 33, 34. Each of them is inserted into the pocket 32 by the deformation of the pair of opposed claws 31a and 31b.
【０００４】[0004]
ところで、上記合成樹脂製保持器においては、軸受が高速回転すると、遠心力 により保持器の爪形成側の一側部が外径方向に拡がって外輪３３の内面あるいは ボール３６に接触し、軸受の回転に支障を及ぼし、高速回転用としての使用に改 善の余地がある。 In the above cage made of synthetic resin, when the bearing rotates at a high speed, one side portion of the cage-forming side of the cage expands in the outer radial direction due to centrifugal force and comes into contact with the inner surface of the outer ring 33 or the ball 36, and It hinders rotation and there is room for improvement in high-speed rotation.
【０００５】 この考案の課題は、高速回転用として使用することができる合成樹脂製保持器 を提供することである。An object of the present invention is to provide a synthetic resin cage that can be used for high speed rotation.
【０００６】[0006]
上記の課題を解決するために、この考案においては、環状の保持器本体の一側 面に対向一対の爪を周方向に等間隔に設け、一対の爪間にボール保持用ポケット を形成し、この保持器本体のポケット開口側の側面に環状の蓋体を連結した構成 を採用したのである。 In order to solve the above-mentioned problems, in the present invention, a pair of opposed pawls are provided at equal intervals in the circumferential direction on one side surface of an annular cage body, and a ball holding pocket is formed between the pair of pawls. A structure was adopted in which an annular lid was connected to the side of the cage body on the pocket opening side.
【０００７】 ここで、蓋体の連結には、保持器本体の隣接するポケット間の隣接する爪間に おける側面と蓋体の対向面一方に連結脚を形成し、その連結脚に先端面で開口す る係合凹部を設け、他方には係合軸部を設け、その係合軸部を係合凹部に挿入す る方法を採用することができる。Here, for connecting the lid body, a connecting leg is formed on one of the side surfaces between the adjacent claws between the adjacent pockets of the cage main body and the facing surface of the lid body, and the connecting leg is formed by the tip end surface. It is possible to adopt a method in which an engaging concave portion to be opened is provided, an engaging shaft portion is provided on the other side, and the engaging shaft portion is inserted into the engaging concave portion.
【０００８】[0008]
上記のように、保持器本体のポケットの開口側の側面に環状の蓋体を取付ける ことによってボールを保持する保持器本体の剛性が高くなり、遠心力によって保 持器本体が外径方向に変形するのを防止することができる。 As described above, the rigidity of the cage body that holds the balls is increased by attaching an annular lid to the side surface of the cage body on the opening side, and the cage body is deformed in the outer diameter direction by centrifugal force. Can be prevented.

【００１６】 軸受に対する保持器の組込みに際しては、ポケット３の開口を前側として保持 器本体１を外輪２０と内輪２１間に挿入し、一対の爪２ａ、２ｂの変形によって 両輪２０、２１間に予め組込まれたボール２２をポケット３内に挿入する（図４ （ロ）参照）。When assembling the retainer to the bearing, the retainer body 1 is inserted between the outer ring 20 and the inner ring 21 with the opening of the pocket 3 on the front side, and the pair of claws 2a and 2b is deformed in advance between the two wheels 20 and 21. The assembled ball 22 is inserted into the pocket 3 (see FIG. 4B).
【００１７】 保持器本体１の組込み後、外輪２０と内輪２１間の他側より蓋体１０を挿入し 、その蓋体１０の係合軸部１２を係合凹部５に圧入し、係合軸部１２と係合凹部 ５の係合によって保持器本体１と蓋体１０とを結合状態に保持する。After the retainer main body 1 is assembled, the lid 10 is inserted from the other side between the outer ring 20 and the inner ring 21, and the engaging shaft portion 12 of the lid body 10 is press-fitted into the engaging recess 5 to form the engaging shaft. The retainer body 1 and the lid body 10 are held in a coupled state by the engagement of the portion 12 and the engagement recess 5.
【００１８】 上記蓋体１０の連結によって保持器本体１の剛性が高くなり、軸受が高速回転 しても保持器本体１は外径方向に変形せず、保持器本体１が軸受の回転に支障を 及ぼすことはない。The rigidity of the retainer main body 1 is increased by the connection of the lid body 10, the retainer main body 1 is not deformed in the outer diameter direction even when the bearing rotates at high speed, and the retainer main body 1 interferes with the rotation of the bearing. Will not be affected.
【００１９】 図１乃至図３に示す実施例では、保持器本体１に係合凹部５を形成し、蓋体１ ０に係合軸部１２を設けたが、保持器本体１に係合軸部を形成し、蓋体１０に係 合凹部を有する連結脚４を設けてもよい。In the embodiment shown in FIGS. 1 to 3, the engaging recess 5 is formed in the retainer body 1 and the engaging shaft portion 12 is provided in the lid body 10. The lid 10 may be provided with a connecting leg 4 having an engaging recess.
