Description

本発明は、アキシャルドロー型により射出成形される樹脂製保持器を備える円すいころ軸受に関する。特に、建設機械フォイールや一般減速器装置に使用される大型薄肉保持器として適用できる。   The present invention relates to a tapered roller bearing including a resin cage that is injection molded by an axial draw mold. In particular, it can be applied as a large thin-walled cage used in construction machine wheels and general speed reducers.

従来のアキシャルドロー型により射出成形される樹脂製保持器を備える円すいころ軸受として、組み立ての際、保持器のポケットに円すいころを保持器の内径側から配置して、その保持器の大径側より内輪を小鍔部側から押し込み、円すいころの最小内径より小鍔部の外径が僅かに大きくしてあることにより、保持器の弾性変形を利用して、円すいころと小鍔部との間にかかり代を作り、組み立てを行うものが知られている（例えば、特許文献１参照）。   As a tapered roller bearing with a resin cage that is injection-molded by a conventional axial draw mold, when assembling, a tapered roller is placed in the cage pocket from the inside diameter side of the cage, and the large diameter side of the cage The inner ring is pushed in from the side of the small flange, and the outer diameter of the small flange is slightly larger than the minimum inner diameter of the tapered roller. There is known a technique for making an allowance in the middle and assembling (for example, see Patent Document 1).

特開２００９−２０９９５２号公報JP 2009-209952 A

しかしながら、上記特許文献１に記載の円すいころ軸受では、円すいころが保持器のポケットに内径側から配置されているだけであるため、組み立ての際に、振動や保持器の変形等によりころがポケットの径方向内側から脱落して、組み込み不良が発生したり、ころが傷ついたりする可能性があった。   However, in the tapered roller bearing described in Patent Document 1, since the tapered roller is merely disposed in the pocket of the cage from the inner diameter side, the roller is not pocketed due to vibration or deformation of the cage during assembly. May fall off from the inside in the radial direction, resulting in poor assembly or damage to the rollers.

また、組み立てを完了した完成品の円すいころ軸受において、装置設備メーカーにて装置設備に軸受を組み込む際、この円すいころ軸受をカップ（円すいころ軸受の外輪のこと）とコーン（内輪、保持器、円すいころの組立体のこと）に分離し、それぞれを装置設備の部品にサブユニットとして組み込んだ後、最終的な組み込みで、カップとコーンを組み合わせる作業を行う場合がある。   In addition, for assembled tapered roller bearings that have been assembled, when the equipment manufacturer incorporates the bearings into the equipment, the tapered roller bearing is replaced with a cup (the outer ring of the tapered roller bearing) and a cone (inner ring, cage, In some cases, the assembly of the cup and the cone is performed in the final assembly after each is assembled as a sub-unit into the parts of the equipment.

この場合、コーンのみを手で持ち上げて運搬することになり、特に、軸受断面が薄く、大きなサイズの軸受であると、全てのころの重量が保持器に掛かることにより撓んで、撓みが一番大きな部位（コーンを縦に持った場合の最も下になる部分）において、ころと内輪の小鍔部の外径との間に隙間が生じ、ころが外力により小鍔部を乗り越え、保持器の内径側から脱落してしまうことがある。また、ころが１つ脱落してしまうと、上記ころと内輪の小鍔部の外径との間の隙間が更に大きくなり、保持器ところは、内輪から外れやすくなり、他のころが脱落してしまう。そして、ころが脱落すると、製品機能に致命的な影響を与える傷を発生させる可能性がある。また、脱落してしまったころを再度保持器に組み込むことは困難であり、製品は使用できなくなってしまう。   In this case, only the cone is lifted and transported by hand. Particularly, in the case of a bearing having a thin bearing cross section and a large size, the weight of all the rollers is bent by the cage, and the bending is the most. In a large part (the lowest part when the cone is held vertically), a gap is created between the roller and the outer diameter of the inner ring's small collar, and the roller gets over the small collar due to external force. It may fall off from the inner diameter side. Also, if one roller falls off, the gap between the roller and the outer diameter of the small collar portion of the inner ring will become larger, and the cage will be easily removed from the inner ring, and the other rollers will fall off. End up. If the rollers fall off, there is a possibility of causing scratches that have a fatal effect on the product function. In addition, it is difficult to reassemble the fallen roller into the cage, and the product cannot be used.

本発明は、前述した事情に鑑みてなされたものであり、その目的は、軸受を組み立てる際、及び軸受を装置設備に組み込む際における円すいころの保持器からの脱落を防止することができる円すいころ軸受を提供することにある。   The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a tapered roller that can prevent the tapered roller from falling off from the cage when the bearing is assembled and when the bearing is incorporated into the equipment. It is to provide a bearing.

以下、本発明に係る円すいころ軸受の一実施形態について、図面に基づいて詳細に説明する。   Hereinafter, an embodiment of a tapered roller bearing according to the present invention will be described in detail based on the drawings.

本実施形態の円すいころ軸受１０は、図１に示すように、内周面に外輪軌道面１１ａを有する外輪１１と、外周面に内輪軌道面１２ａを有する内輪１２と、外輪軌道面１１ａと内輪軌道面１２ａとの間に転動可能に配設される複数の円すいころ１３と、複数の円すいころ１３を円周方向に等間隔に保持する保持器２０と、を備える。また、内輪１２の軸方向端部には、小鍔部１２ｂ及び大鍔部１２ｃがそれぞれ形成される。   As shown in FIG. 1, the tapered roller bearing 10 of this embodiment includes an outer ring 11 having an outer ring raceway surface 11a on an inner peripheral surface, an inner ring 12 having an inner ring raceway surface 12a on an outer peripheral surface, an outer ring raceway surface 11a and an inner ring. A plurality of tapered rollers 13 disposed so as to be able to roll between the raceway surface 12a and a cage 20 that holds the plurality of tapered rollers 13 at equal intervals in the circumferential direction. Further, a small flange portion 12b and a large flange portion 12c are formed at the axial end portion of the inner ring 12, respectively.

保持器２０は、図２及び図３に示すように、アキシャルドロー型による合成樹脂の射出成形によって形成されるもので、小径側円環部２１と、大径側円環部２２と、小径側円環部２１及び大径側円環部２２を軸方向に連結し、円周方向に略等間隔に設けられる複数の柱部２３と、円周方向に互いに隣り合う柱部２３間に形成され円すいころ１３を転動可能に保持するポケット２４と、を備える。   As shown in FIGS. 2 and 3, the cage 20 is formed by injection molding of a synthetic resin by an axial draw type, and includes a small-diameter side annular part 21, a large-diameter side annular part 22, and a small-diameter side. The annular portion 21 and the large-diameter side annular portion 22 are connected in the axial direction, and are formed between a plurality of column portions 23 provided at substantially equal intervals in the circumferential direction and the column portions 23 adjacent to each other in the circumferential direction. And a pocket 24 for holding the tapered roller 13 in a rollable manner.

そして、本実施形態では、各柱部２３の内周面の小径側部分に、円すいころ１３の脱落を防止する突起部２５が小径側円環部２１に連続してそれぞれ形成されており、これにより、軸受１０を組み立てる際、及び軸受１０を装置設備に組み込む際における円すいころ１３のポケット２４の径方向内側からの脱落が防止されると共に、保持器２０の剛性が高められている。また、突起部２５は、円すいころ１３の脱落を防止するために、保持器２０の軸方向視において略台形状に形成されている。また、突起部２５は、ポケット２４に挿入された円すいころ１３と接触しないため、円すいころ１３の回転を妨げることはない。また、保持器２０を二分割の金型から軸方向へ取り出し易くするため、突起部２５の内周面は、小径側円環部２１の内周面と面一に形成される。   And in this embodiment, the projection part 25 which prevents the fall off of the tapered roller 13 is formed in the small diameter side part of the internal peripheral surface of each pillar part 23 continuously with the small diameter side annular part 21, respectively. Thus, when the bearing 10 is assembled and when the bearing 10 is incorporated into the equipment, the tapered roller 13 is prevented from falling off from the inside of the pocket 24 in the radial direction, and the rigidity of the cage 20 is enhanced. Further, the protrusion 25 is formed in a substantially trapezoidal shape when the cage 20 is viewed in the axial direction in order to prevent the tapered roller 13 from falling off. Moreover, since the protrusion part 25 does not contact the tapered roller 13 inserted into the pocket 24, it does not hinder the rotation of the tapered roller 13. Moreover, in order to make it easy to take out the retainer 20 from the two-part mold in the axial direction, the inner peripheral surface of the protrusion 25 is formed flush with the inner peripheral surface of the small-diameter side annular portion 21.

また、本実施形態では、突起部２５は、アキシャルドロー型による保持器２０の射出成形と同時に形成される。   Moreover, in this embodiment, the protrusion part 25 is formed simultaneously with the injection molding of the holder | retainer 20 by an axial draw type.

以上説明したように、本実施形態の円すいころ軸受１０によれば、各柱部２３の内周面の小径側部分に、円すいころ１３が保持器２０の径方向内側から脱落することを防止する突起部２５が設けられるため、軸受１０を組み立てる際、及び軸受１０を装置設備に組み込む際における円すいころ１３の保持器２０からの脱落を防止することができ、円すいころ１３は保持器２０の径方向内側から組み込まれる。また、突起部２５を設けることにより、保持器２０の剛性を高めることができるので、軸受１０を装置設備に組み込む際の保持器２０の変形を小さくすることができる。   As described above, according to the tapered roller bearing 10 of the present embodiment, the tapered roller 13 is prevented from falling off from the radially inner side of the cage 20 on the small diameter side portion of the inner peripheral surface of each column portion 23. Since the protrusion 25 is provided, it is possible to prevent the tapered roller 13 from falling off from the cage 20 when the bearing 10 is assembled and when the bearing 10 is assembled into the equipment. The tapered roller 13 has a diameter of the cage 20. Built in from the inside. Moreover, since the rigidity of the retainer 20 can be increased by providing the projecting portion 25, the deformation of the retainer 20 when the bearing 10 is incorporated into the equipment can be reduced.

なお、本実施形態の変形例として、図４〜図６に示すように、突起部２５は、円すいころ１３をポケット２４に挿入できる範囲内において、大径側円環部２２に向かって延設されていてもよい。この場合、突起部２５の延設された部分は、大径側円環部２２に向かうに従って周方向幅が狭くなるように略台形状に形成されている。そして、本変形例によれば、柱部２３の剛性を高めることができるので、軸受１０を装置設備に組み込む際の保持器２０の変形を更に小さくすることができる。   As a modification of the present embodiment, as shown in FIGS. 4 to 6, the protrusion 25 extends toward the large-diameter annular portion 22 within a range in which the tapered roller 13 can be inserted into the pocket 24. May be. In this case, the extended portion of the protrusion 25 is formed in a substantially trapezoidal shape such that the circumferential width becomes narrower toward the large-diameter side annular portion 22. And according to this modification, since the rigidity of the pillar part 23 can be improved, the deformation | transformation of the holder | retainer 20 at the time of incorporating the bearing 10 in apparatus equipment can be made still smaller.

なお、本発明は上記実施形態に例示したものに限定されるものではなく、本発明の要旨を逸脱しない範囲において適宜変更可能である。   In addition, this invention is not limited to what was illustrated to the said embodiment, In the range which does not deviate from the summary of this invention, it can change suitably.
