Description

本発明は、例えば、連続鋳造設備におけるスラブ搬送用杵型ロールの回転支持部に用いられる円筒ころ軸受等の転がり軸受に装着されるシール部材及び該シール部材を備えた転がり軸受に関する。   The present invention relates to, for example, a seal member mounted on a rolling bearing such as a cylindrical roller bearing used in a rotation support portion of a saddle roll for conveying a slab in a continuous casting facility, and a rolling bearing provided with the seal member.

従来のこの種の転がり軸受としては、例えば、図４に示す連続鋳造設備用の円筒ころ軸受が知られている。
この円筒ころ軸受は、連続鋳造設備におけるスラブ搬送用杵型ロールの自由端側を回転可能に支持するためのものであり、外輪（軌道輪）１と内輪（軌道輪）２との間に転動体としての複数の円筒ころ３が周方向に転動可能に配設され、外輪１の外周面に形成された凸球面部１ａに、内周面に凸球面部１ａに対応する凹球面部４ａを有する調芯輪４が外嵌されて、調芯機能が付与されている。
外輪１の軸方向の両端部内周面には、それぞれシール装着溝５が形成されており、該シール装着溝５には、シール部材６の外径部が装着され、該シール部材６の内径側のシールリップ６ａは、軸受回転時に内輪２の外周面（軌道面）に摺接するようになっている。 As a conventional rolling bearing of this type, for example, a cylindrical roller bearing for continuous casting equipment shown in FIG. 4 is known.
This cylindrical roller bearing is for rotatably supporting the free end side of the saddle type roll for slab conveyance in a continuous casting facility, and is rolled between an outer ring (track ring) 1 and an inner ring (track ring) 2. A plurality of cylindrical rollers 3 as moving bodies are disposed so as to be able to roll in the circumferential direction, and a concave spherical surface portion 4 a corresponding to the convex spherical surface portion 1 a on the inner peripheral surface is formed on the convex spherical surface portion 1 a formed on the outer peripheral surface of the outer ring 1. The centering ring 4 having the above is fitted on the outside to provide a centering function.
Seal mounting grooves 5 are formed on the inner peripheral surfaces of both ends in the axial direction of the outer ring 1, and the outer diameter portion of the seal member 6 is mounted in the seal mounting groove 5, and the inner diameter side of the seal member 6 The seal lip 6a is in sliding contact with the outer peripheral surface (track surface) of the inner ring 2 when the bearing rotates.

上記従来の円筒ころ軸受においては、一般に、シール部材６の外径側装着部の軸方向幅内にシール部材６全体が配置されており、内径側のシールリップ６ａはシール部材６の軸方向外側を向く端面と略同一位置に配置されている。
ところで、連続鋳造設備に用いられる円筒ころ軸受では、スラブの熱によるロールの軸方向への伸縮により、内輪２に対して、軸方向に移動可能な軌道面の軸方向寸法である許容移動寸法Ｈを設定しておくことが必要である。この許容移動寸法Ｈとは、シール部材６のシールリップ６ａ位置から内輪２の軌道面と軸方向端面との間の面取り部２ａまでの寸法である。 In the conventional cylindrical roller bearing described above, generally, the entire seal member 6 is disposed within the axial width of the outer diameter side mounting portion of the seal member 6, and the seal lip 6 a on the inner diameter side is the outer side in the axial direction of the seal member 6. It is arrange | positioned in the substantially the same position as the end surface which faces.
By the way, in the cylindrical roller bearing used for the continuous casting equipment, the allowable movement dimension H which is the axial dimension of the raceway surface movable in the axial direction with respect to the inner ring 2 by the expansion and contraction of the roll in the axial direction due to the heat of the slab. Must be set in advance. The allowable movement dimension H is a dimension from the position of the seal lip 6a of the seal member 6 to the chamfered portion 2a between the raceway surface of the inner ring 2 and the end surface in the axial direction.

しかしながら、上記従来の円筒ころ軸受においては、シール部材６の内径側のシールリップ６ａが、該シール部材６の軸方向外側を向く端面と略同一位置に配置されているため、前記許容移動寸法Ｈを大きく取るには、内輪２の軸方向長さを長くするか、円筒ころ３の軸方向長さを短くせざるを得ない。
この場合、内輪２の軸方向長さを長くすると、軸受幅寸法が長くなって、軸受ひいては設備の大型化を招く原因になり、円筒ころ３の軸方向長さを短くすると、軸受の負荷容量が低下してしまうという問題が生じる。 However, in the above-described conventional cylindrical roller bearing, the seal lip 6a on the inner diameter side of the seal member 6 is disposed at substantially the same position as the end surface facing the axially outer side of the seal member 6, so that the allowable movement dimension H In order to obtain a large value, it is necessary to increase the axial length of the inner ring 2 or shorten the axial length of the cylindrical roller 3.
In this case, if the length of the inner ring 2 in the axial direction is increased, the bearing width is increased, which causes an increase in the size of the bearing and thus the equipment. If the axial length of the cylindrical roller 3 is shortened, the load capacity of the bearing is increased. This causes a problem of lowering.

本発明はこのような不都合を解消するためになされたものであり、軸受の負荷容量を低下させることなく、シール部材のシールリップが配置される側の軌道輪の軸方向の許容移動寸法を大きく取ることができる転がり軸受のシール部材及び転がり軸受を提供することを目的とする。   The present invention has been made to eliminate such inconveniences, and without increasing the load capacity of the bearing, increases the allowable movement dimension in the axial direction of the bearing ring on the side where the seal lip of the seal member is disposed. It is an object of the present invention to provide a rolling bearing seal member and a rolling bearing that can be taken.

本発明によれば、一対の軌道輪のうちの一方の軌道輪の軸方向端部に装着されたシール部材のシールリップを、該シール部材の装着位置に対して、他方の軌道輪の軸方向端面から離間する側に配置しているので、転動体の軸方向寸法を短くすることなく、シールリップの位置と他方の軌道輪の軸方向端面との寸法を長くすることができる。これにより、軸受の負荷容量を低下させることなく、シール部材のシールリップが配置される側の軌道輪である他方の軌道輪の軸方向の許容移動寸法を大きく取ることができる。   According to the present invention, the seal lip of the seal member mounted on the axial end portion of one of the pair of track rings is moved in the axial direction of the other track ring with respect to the mounting position of the seal member. Since it arrange | positions in the side spaced apart from an end surface, the dimension of the position of a seal lip and the axial direction end surface of the other track ring can be lengthened, without shortening the axial direction dimension of a rolling element. Thereby, the allowable movement dimension in the axial direction of the other bearing ring which is the bearing ring on the side where the seal lip of the seal member is disposed can be increased without reducing the load capacity of the bearing.

以下、本発明の実施の形態の一例を図を参照して説明する。図１は本発明の実施の形態の一例である円筒ころ軸受を説明するための要部断面図、図２及び図３は本発明の他の実施の形態である円筒ころ軸受を説明するための要部断面図である。なお、この実施の形態では、転がり軸受として、連続鋳造設備におけるスラブ搬送用杵型ロールの自由端側を回転可能に支持する円筒ころ軸受を例に採る。   Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of an essential part for explaining a cylindrical roller bearing which is an example of an embodiment of the present invention, and FIGS. 2 and 3 are for explaining a cylindrical roller bearing which is another embodiment of the present invention. It is principal part sectional drawing. In this embodiment, a cylindrical roller bearing that rotatably supports the free end side of the saddle roll for slab conveyance in the continuous casting facility is taken as an example of the rolling bearing.

本発明の実施の形態の一例である円筒ころ軸受１０は、外輪（軌道輪）１１の軌道面１１１ａと内輪（軌道輪）１２の軌道面１２ａとの間に転動体としての複数の円筒ころ１３が周方向に転動可能に配設されており、外輪１１の軌道面１１ａの軸方向の両端側には、それぞれ鍔部１４が設けられている。
また、外輪１１の外周面には、調芯座としての凸球面部１５が形成されており、この凸球面部１５に、内周面に該凸球面部１５に対応する凹球面部１６を有する調芯輪１７が外嵌されて、調芯機能が付与されている。この調芯機能により、ロールの撓み等による軸心ずれを吸収することができる。 A cylindrical roller bearing 10, which is an example of an embodiment of the present invention, includes a plurality of cylindrical rollers 13 as rolling elements between a raceway surface 111 a of an outer ring (track ring) 11 and a raceway surface 12 a of an inner ring (track ring) 12. Are arranged so as to be able to roll in the circumferential direction, and flanges 14 are provided on both end sides of the raceway surface 11a of the outer ring 11 in the axial direction.
A convex spherical surface 15 as a centering seat is formed on the outer peripheral surface of the outer ring 11. The convex spherical portion 15 has a concave spherical portion 16 corresponding to the convex spherical portion 15 on the inner peripheral surface. A centering ring 17 is fitted on the outside to provide a centering function. This alignment function can absorb axial misalignment due to roll deflection or the like.

外輪１１の両鍔部１４の軸方向の外側内周面には、それぞれシール装着溝１８が形成されており、該シール装着溝１８には、シール部材２０の外径部が装着されている。
シール部材２０は、例えば、芯金にゴム等の弾性材が一体に成形されたものであり、弾性材の内径側にシールリップ２２が設けられ、該シールリップ２２が、軸受回転時に内輪１２の軌道面１２ａに摺接するようになっている。また、内輪１２の軌道面１２ａと軸方向端面との間には、面取り部２３が形成されている。 A seal mounting groove 18 is formed on each of the outer peripheral surfaces in the axial direction of both flange portions 14 of the outer ring 11, and an outer diameter portion of a seal member 20 is mounted in the seal mounting groove 18.
The seal member 20 is formed by integrally molding an elastic material such as rubber on a core metal, for example, and a seal lip 22 is provided on the inner diameter side of the elastic material, and the seal lip 22 is formed on the inner ring 12 when the bearing rotates. It is in sliding contact with the raceway surface 12a. Further, a chamfered portion 23 is formed between the raceway surface 12 a of the inner ring 12 and the axial end surface.

ここで、この実施の形態では、シール部材２０の内径側のシールリップ２２を、該シール部材２０の軸方向外側を向く端面より軸方向内側、即ち、内輪１２の軸方向端面から離間する側に配置している。これにより、円筒ころ１３の軸方向長さを短くすることなく、シールリップ２２の位置から内輪１２の軌道面１２ａの面取り部２３までの寸法を長くすることができる。   Here, in this embodiment, the seal lip 22 on the inner diameter side of the seal member 20 is arranged on the inner side in the axial direction from the end surface facing the outer side in the axial direction of the seal member 20, that is, on the side away from the end surface in the axial direction of the inner ring 12. It is arranged. Thereby, the dimension from the position of the seal lip 22 to the chamfered portion 23 of the raceway surface 12a of the inner ring 12 can be increased without reducing the axial length of the cylindrical roller 13.

このように、この実施の形態では、シール部材２０の内径側のシールリップ２２を、該シール部材２０の軸方向外側を向く端面より軸方向内側に配置しているので、円筒ころ１３の軸方向長さを短くすることなく、シールリップ２２の位置から内輪１２の軌道面１２ａの面取り部２３までの寸法を長くすることができ、この結果、軸受の負荷容量を低下させることなく、内輪１２の軌道面１２ａの軸方向の許容移動寸法Ｈを大きく取ることができる。   As described above, in this embodiment, the seal lip 22 on the inner diameter side of the seal member 20 is disposed on the inner side in the axial direction from the end surface facing the outer side in the axial direction of the seal member 20. Without shortening the length, the dimension from the position of the seal lip 22 to the chamfered portion 23 of the raceway surface 12a of the inner ring 12 can be increased. As a result, the inner ring 12 can be reduced without reducing the load capacity of the bearing. The allowable movement dimension H in the axial direction of the raceway surface 12a can be increased.

また、許容移動寸法Ｈを従来より大きく取る必要がない場合は、その分、軸受幅寸法を短くすることができるので、軸受のコンパクト化を図ることができる。
なお、本発明の一対の軌道輪、シール部材、シールリップ及び転動体等の構成は上記実施の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。 Further, when it is not necessary to make the allowable movement dimension H larger than the conventional one, the bearing width dimension can be shortened accordingly, so that the bearing can be made compact.
The configurations of the pair of race rings, the seal member, the seal lip, and the rolling element of the present invention are not limited to those illustrated in the above embodiment, and can be appropriately changed without departing from the gist of the present invention. It is.

例えば、上記実施の形態では、軸受の軸方向中心位置に対して、軸方向の両方向の移動に対応するために、外輪１１の軸方向の両端部にそれぞれシール部材２０を装着した場合を例示したが、これに限定されず、軸方向の一方向（図２の左方向）だけの許容移動寸法Ｈを要求（構造上の要求）された場合には、図２に示すように、外輪１１の軸方向の一端部（図２の右端部）のみにシール部材２０を装着するようにしてもよい。この場合、円筒ころ１３は、左端側の鍔部１４の必要な軸方向幅を確保しつつ、軸受の軸方向中心位置より左端側にオフセットして配置されている。   For example, in the above-described embodiment, the case where the seal members 20 are respectively attached to both end portions in the axial direction of the outer ring 11 in order to cope with movement in both axial directions with respect to the axial center position of the bearing is illustrated. However, the present invention is not limited to this, and when an allowable movement dimension H in only one axial direction (left direction in FIG. 2) is required (a structural requirement), as shown in FIG. The seal member 20 may be attached only to one end portion in the axial direction (the right end portion in FIG. 2). In this case, the cylindrical roller 13 is disposed offset to the left end side from the axial center position of the bearing while ensuring the necessary axial width of the flange portion 14 on the left end side.

また、上記実施の形態では、外輪１１と内輪１２との軸方向寸法を略同一とした場合を例示したが、前記許容移動寸法Ｈが不足する場合には、図３に示すように、外輪１１の軸方向寸法より内輪１２の軸方向寸法を長くして、該許容移動寸法Ｈをさらに大きく取るようにしてもよい。
さらに、上記実施の形態では、転動体として円筒ころ１３を用いた円筒ころ軸受１０に本発明を適用した場合を例示したが、これに代えて、転動体として針状ころを用いた針状ころ軸受に本発明を適用してもよい。 In the above embodiment, the case where the outer ring 11 and the inner ring 12 have substantially the same axial dimension is illustrated. However, when the allowable movement dimension H is insufficient, as shown in FIG. The axial dimension of the inner ring 12 may be made longer than the axial dimension, and the allowable movement dimension H may be further increased.
Furthermore, in the said embodiment, although the case where this invention was applied to the cylindrical roller bearing 10 using the cylindrical roller 13 as a rolling element was illustrated, it replaced with this and the needle roller which used the needle roller as a rolling element was illustrated. The present invention may be applied to a bearing.

さらに、上記実施の形態では、シール部材２０の外径部を外輪１１側に装着した場合を例示したが、これに代えて、シール部材の内径部を内輪側に装着して、外径側にシールリップを配置するようにしてもよい。
さらに、上記実施の形態では、連続鋳造設備に用いられる円筒ころ軸受に本発明を適用した場合を例示したが、これに代えて、例えば、中大型電動機や製紙機械等の回転支持部に用いられる円筒ころ軸受等の転がり軸受に本発明を適用してもよい。 Furthermore, in the above embodiment, the case where the outer diameter portion of the seal member 20 is mounted on the outer ring 11 side is illustrated, but instead, the inner diameter portion of the seal member is mounted on the inner ring side and A seal lip may be arranged.
Furthermore, in the said embodiment, although the case where this invention was applied to the cylindrical roller bearing used for a continuous casting installation was illustrated, it replaces with this, for example, is used for rotation support parts, such as a medium-sized motor and a papermaking machine. The present invention may be applied to a rolling bearing such as a cylindrical roller bearing.
