Description
【０００１】[0001]
本考案は、分割形転がり軸受用保持器に関する。 The present invention relates to a cage for split rolling bearings.
【０００２】[0002]
例えば、クランク軸や長軸、あるいは、圧延機用ロールのロールネックといっ た軸受の組み付けが困難な箇所には分割形軸受が使用される場合が多い。分割形 軸受は、内・外輪、保持器といった環状の軸受部品をすべて２分割構造とし、組 み付け後に、分割した軸受部品をそれぞれ相互に連結して環状に一体化するもの である。 For example, split bearings are often used in places where it is difficult to assemble the bearings, such as the crankshaft, the long shaft, or the roll neck of a rolling mill roll. The split type bearing has a structure in which the annular bearing parts such as the inner and outer rings and the cage are all divided into two parts, and after assembly, the divided bearing parts are connected to each other and integrated into an annular shape.
【０００３】 図３に一例として示すのは、分割形スラスト円筒ころ軸受の保持器である。こ の保持器は、半円状に分割した２つの保持器分割体３２、３３を割り口３２ａ、 ３３ａで相互に合わせ、この合わせ部に連結した連結板３５を介して両者を環状 に連結一体化したものである。連結板３５は、割り口３２ａ、３３ａに設けられ た凹所によって形成される空間部に収容され、皿鋲３６およびノックピン３７で 保持器本体３２、３３に連結されている。An example shown in FIG. 3 is a cage of a split type thrust cylindrical roller bearing. In this cage, two cage divided bodies 32 and 33, which are divided into semicircles, are fitted to each other at the split ports 32a and 33a, and both are annularly connected and integrated via a connecting plate 35 connected to this mating portion. It has been transformed. The connecting plate 35 is accommodated in the space formed by the recesses provided in the split openings 32a and 33a, and is connected to the retainer bodies 32 and 33 by the flat tack 36 and the knock pin 37.
【０００４】[0004]
軸受回転時、保持器には転動体の遅れ進み等によって円周方向の引張力が発生 するが、上記構成の保持器ではこの引張力が皿鋲３６およびノックピン３７に剪 断力として直接作用する。そのため、長期使用により、皿鋲３６およびノックピ ン３７に強度上の懸念が生じる可能性がある。また、保持器に触れ回りが生じる ような場合には半径方向のずれ力が発生するので、同様の懸念が生じる可能性が ある。 When the bearing rotates, a tensile force in the circumferential direction is generated in the cage due to the lag and advance of the rolling elements, etc., but in the cage of the above configuration, this tensile force directly acts on the flat tack 36 and the knock pin 37 as a shearing force. . Therefore, long-term use may cause concern about the strength of the flat tack 36 and the knock pin 37. In addition, when the cage is touched around, a radial displacement force is generated, which may cause the same concern.
【０００５】 本考案は、上記問題点に鑑み、分割形転がり軸受用保持器における連結部の強 度向上を図ることをその目的とするものである。In view of the above problems, it is an object of the present invention to improve the strength of a connecting portion in a cage for split type rolling bearings.
【０００６】[0006]
本考案の分割形転がり軸受用保持器は、半円状に分割した２つの保持器分割体 を割り口部分で相互に合わせ、この合わせ部に連結した連結板を介して、２つの 保持器分割体を環状に連結一体化したものであって、保持器分割体と連結板とを 、保持器分割体相互の離反方向に拘束する凹凸構造を有するものである。 The cage for split rolling bearings according to the present invention is such that two cage divided bodies which are divided into semicircles are aligned with each other at a split portion, and the two cage divided through a connecting plate connected to this mating portion. A body is connected and integrated in an annular shape, and has a concavo-convex structure for constraining the cage divided body and the connecting plate in the direction in which the cage divided bodies are separated from each other.
【０００７】[0007]
軸受回転時、保持器の連結部に作用する力が、保持器分割体と連結板との凹凸 構造で負荷されるので、保持器分割体と連結板とを連結する連結手段にかかる力 が軽減される。 When the bearing is rotated, the force acting on the cage connecting part is applied by the uneven structure of the cage split body and the connecting plate, so the force applied to the connecting means connecting the cage split body and the connecting plate is reduced. To be done.
【０００８】[0008]
以下、本考案の実施例を図面に従って説明する。 Embodiments of the present invention will be described below with reference to the drawings.
【０００９】 図１に示す実施例は、本考案を分割形スラスト円筒ころ軸受の保持器に適用し たものである。この保持器１は、分割線Ｌに沿って半円状に分割した２つの保持 器分割体２、３を割り口２ａ、３ａで相互に合わせ、この合わせ部に連結した連 結板５を介して両者を環状に連結一体化したものである。一体化された保持器１ には、ころ（図示省略）を収容する複数のポケット１ａが円周等間隔に形成され る。尚、分割手段には自然分割（剪断力による破断）と機械分割（切断等）とが あり、本考案はそのいずれとを問わないが、この実施例では歩留まりの良さ、割 り口２ａと割り口３ａとの適合性の良さを考慮して自然分割を採用している。The embodiment shown in FIG. 1 is an application of the present invention to a cage of a split type thrust cylindrical roller bearing. In this cage 1, two cage divided bodies 2 and 3 which are divided into semicircles along a dividing line L are aligned with each other at split ports 2a and 3a, and a connecting plate 5 connected to this mating portion is interposed. The two are connected and integrated in a ring. In the integrated cage 1, a plurality of pockets 1a for accommodating rollers (not shown) are formed at equal intervals around the circumference. The dividing means includes natural dividing (breaking due to shearing force) and mechanical dividing (cutting, etc.), and the present invention may be either of them, but in this embodiment, the good yield and the dividing opening 2a are used. The natural division is adopted in consideration of good compatibility with the mouth 3a.
【００１０】 図２に拡大して示すように（図１ａにおけるｃ−ｃ断面）、保持器分割体２、 ３の端面に、それぞれ、割り口２ａ、３ａ側から段部２ｂ、３ｂを設け、さらに 、段部２ｂ、３ｂの側壁側に凹溝２ｃ、３ｃを設けてある。連結板５は断面Ｕ字 状のもので、その周方向両側に凸部５ａ、５ｂを設けてある。そして、連結板５ を、段部２ｂ、３ｂとで形成される凹所に凸部５ａ、５ｂ側から装着し、凸部５ ａ、５ｂを凹溝２ｃ、３ｃに嵌め込んだ状態で、段部２ｂ、３ｂの底壁にねじ６ で連結している。As shown in an enlarged view in FIG. 2 (cc cross section in FIG. 1a), step portions 2b and 3b are provided on the end faces of the cage divided bodies 2 and 3 from the split ports 2a and 3a side, respectively. Furthermore, concave grooves 2c and 3c are provided on the side walls of the stepped portions 2b and 3b. The connecting plate 5 has a U-shaped cross section and is provided with projections 5a and 5b on both sides in the circumferential direction. Then, the connecting plate 5 is attached to the concave portion formed by the step portions 2b and 3b from the convex portions 5a and 5b side, and the convex portions 5a and 5b are fitted into the concave grooves 2c and 3c. Screws 6 are connected to the bottom walls of the parts 2b and 3b.
【００１１】 凸部５ａ、５ｂ間の内側寸法Ｓ１は、割り口２ａ、３ａを密着させた状態にお ける凹溝２ｃ、３ｃの壁面間寸法Ｓ２と略等しく、凸部５ａ、５ｂが凹溝２ｃ、 ３ｃに嵌まり込むことで、保持器分割体２、３相互間の周方向位置決めがなされ る。さらに、保持器分割体２、３を周方向に離反させようとする力に対して、凸 部５ａ、５ｂと凹溝２ｃ、３ｃとの係合力によりこれが負荷されるので、ねじ６ にかかる力が軽減され、長期の使用にも十分耐え得るだけの強度が担保される。 尚、保持器１の触れ回りなどにより、保持器分割体２、３を半径方向に離反させ ようとする力が発生するような場合には、上記構成に加え、連結板５の半径方向 両側に同様の凹凸構造を設けても良い。ただ、この実施例のように、割り口２ａ 、３ａを自然分割とすることにより、割り口２ａ、３ａ同士の適合によって半径 方向のずれが抑制されるので、通常の使用条件下では、さらに凹凸構造を付加す る必要性は少ない。勿論、割り口を機械分割とした場合でも、強度としては十分 である。The inner dimension S1 between the convex portions 5a and 5b is substantially equal to the dimension S2 between the wall surfaces of the concave grooves 2c and 3c in the state where the split openings 2a and 3a are in close contact, and the convex portions 5a and 5b are concave grooves. By being fitted into 2c and 3c, the cage divided bodies 2 and 3 are circumferentially positioned with respect to each other. Further, since the engaging force between the convex portions 5a and 5b and the concave grooves 2c and 3c is applied to the force for separating the cage divided bodies 2 and 3 in the circumferential direction, the force applied to the screw 6 Is reduced, and the strength is ensured to withstand long-term use. In addition, in the case where a force for separating the cage divided bodies 2 and 3 in the radial direction is generated due to the contact of the cage 1 or the like, in addition to the above-mentioned configuration, the connecting plate 5 is provided on both sides in the radial direction. You may provide the same uneven structure. However, by naturally dividing the slits 2a 1 and 3a as in this embodiment, the radial deviation is suppressed by the fitting of the slits 2a and 3a, so that under normal use conditions, the unevenness is further reduced. There is little need to add structure. Of course, even if the split is machine-divided, the strength is sufficient.
【００１２】 以上の説明は、本考案を分割形スラスト円筒ころ軸受の保持器に適用した場合 についてものであるが、本考案はこれに限定されず、広く、分割形転がり軸受用 保持器一般に適用可能である。また、凹凸構造は、保持器分割体を離反方向に拘 束し得るものであればよく、その形状・寸法などは特に問わない。The above description is for the case where the present invention is applied to the cage of the split type thrust cylindrical roller bearing, but the present invention is not limited to this, and is widely applied to the split type rolling bearing cage in general. It is possible. Further, the concavo-convex structure may be any structure as long as it can constrain the cage divided bodies in the separating direction, and the shape and dimensions thereof are not particularly limited.
【００１３】[0013]
以上説明したように、本考案の分割形転がり軸受用保持器は、保持器分割体と 連結板とを、保持器分割体相互の離反方向に拘束する凹凸構造を有するので、離 反方向の力がこの凹凸構造で負荷され、連結板と保持器分割体とを連結する連結 手段にかかる力が軽減される。したがって、本考案によれば、分割形転がり軸受 用保持器の連結部における強度上の懸念を解消することができ、軸受の最適運転 を長期にわたって確保することができる。 As described above, the cage for split rolling bearings according to the present invention has the concavo-convex structure for restraining the cage split and the connecting plate in the direction in which the cage splits are separated from each other. However, the force applied to the connecting means for connecting the connecting plate and the cage divided body is reduced. Therefore, according to the present invention, it is possible to eliminate the concern about the strength of the connecting portion of the cage for split rolling bearings, and it is possible to ensure the optimum operation of the bearing for a long period of time.
