Abstract

PROBLEM TO BE SOLVED: To prevent a synthetic-resin-made cage from getting damaged even if the cage largely expands when in use and comes into contact with an outer ring raceway surface in a roller bearing having the cage.SOLUTION: An outer diameter surface 43a of a column portion 43 of the cage 4 is dented from outer peripheral surfaces of a large-diameter side annular portion 41 and a small-diameter side annular portion 42 to have the cage 4 guided by the contact of the outer peripheral surfaces of both the annular portions 41 and 42 with a raceway surface 2a of an outer ring 2. Intervals between the outer peripheral surface and the raceway surface 2a of the outer ring 2, at the large-diameter side annular portion 41 and the small-diameter side annular portion 42 of the cage 4, are the same or approximately the same.

Description

この発明は、合成樹脂製の保持器を備えたころ軸受に関する。   The present invention relates to a roller bearing provided with a cage made of synthetic resin.

円錐ころ軸受は、内輪および外輪の軌道面ところをなす円錐の頂点が、軸受中心軸上の一点に集まるように設計されている。そのため、図４に示すように、円錐ころ軸受の内輪１および外輪２の軌道面１ａ，２ａは軸方向に傾斜し、内輪１の外周面の傾斜した軌道面１ａの小径側に小鍔部１１が形成され、大径側に大鍔部１２が形成されている。
また、ころ３を保持する保持器４は、大径側環状部４１と小径側環状部４２と両環状部４１，４２を連結する柱部４３とからなり、周方向で隣り合う柱部４３と両環状部４１，４２とで、ころ３を保持するポケット４４が形成されている。
特許文献１には、合成樹脂製で図３に示す形状の保持器４を用いた円錐ころ軸受が記載されている。この円錐ころ軸受においては、外輪２の軌道面２ａの軸線に対する傾斜角度θ1 が、保持器４の柱部４３の外径面の軸線に対する傾斜角度θ2 より大きく形成されている。 The tapered roller bearing is designed so that the apexes of the cones forming the raceway surfaces of the inner ring and the outer ring are gathered at one point on the bearing central axis. Therefore, as shown in FIG. 4, the raceway surfaces 1 a and 2 a of the inner ring 1 and the outer ring 2 of the tapered roller bearing are inclined in the axial direction, and a small flange portion 11 is formed on the small diameter side of the inclined raceway surface 1 a of the outer peripheral surface of the inner ring 1. The large collar portion 12 is formed on the large diameter side.
The cage 4 that holds the rollers 3 includes a large-diameter-side annular portion 41, a small-diameter-side annular portion 42, and a column portion 43 that connects both the annular portions 41, 42. A pocket 44 for holding the roller 3 is formed by both the annular portions 41 and 42.
Patent Document 1 describes a tapered roller bearing made of a synthetic resin and using a cage 4 having the shape shown in FIG. In this tapered roller bearing, the inclination angle θ 1 with respect to the axis of the raceway surface 2 a of the outer ring 2 is formed larger than the inclination angle θ 2 with respect to the axis of the outer diameter surface of the column part 43 of the cage 4.

また、合成樹脂製の保持器４を軸方向に分割する金型（２枚の型板）によって射出成形すると、大径側環状部４１側の型板の形状に伴って、図５に示すように、柱部４３の外径面４３１に欠損面４３２が生じることが記載されている。なお、図４および５に、柱部４３の外径面４３１と欠損面４３２との角度をθ3 で示す。
特許文献２には、円錐ころ軸受の合成樹脂製保持器に、円錐ころの大径側端面および小径側端面を各端面の中心で支持する突起部を設けることで、円錐ころの端面と保持器との接触部に生じる摩擦抵抗を低減することが記載されている。 Further, when the synthetic resin cage 4 is injection-molded with a mold (two mold plates) that is divided in the axial direction, the shape of the mold plate on the large-diameter side annular portion 41 side is shown in FIG. In addition, it is described that a defect surface 432 is generated on the outer diameter surface 431 of the column portion 43. 4 and 5, the angle between the outer diameter surface 431 of the pillar portion 43 and the defect surface 432 is indicated by θ 3 .
In Patent Document 2, the end surface of the tapered roller and the cage are provided on the synthetic resin cage of the tapered roller bearing by providing a protrusion that supports the large-diameter side end surface and the small-diameter side end surface of the tapered roller at the center of each end surface. It is described that the frictional resistance generated in the contact portion with the head is reduced.

合成樹脂製保持器を備えた円錐ころ軸受は、合成樹脂の線膨張係数が金属よりも大きいため、高温または高湿条件で使用した場合に、保持器が大きく膨張して外輪軌道面に接触する可能性がある。
その場合、特許文献１および２に記載された形状の保持器では、柱部の外径面が外輪軌道面に接触することになり、柱部が外輪の軌道面ところの転動面との間に挟まれる恐れがある。これに伴って、ころが保持器の柱部に乗り上がると保持器に損傷が生じる可能性がある。
この発明の課題は、合成樹脂製保持器を備えたころ軸受において、使用時に保持器が大きく膨張して外輪軌道面と接触した場合でも、保持器に破損が生じないようにすることである。 A tapered roller bearing with a synthetic resin cage has a larger linear expansion coefficient than that of metal. Therefore, when used at high temperature or high humidity, the cage expands greatly and comes into contact with the outer ring raceway surface. there is a possibility.
In that case, in the cage having the shape described in Patent Documents 1 and 2, the outer diameter surface of the column portion comes into contact with the outer ring raceway surface, and the column portion is between the raceway surface of the outer ring raceway surface. There is a risk of being caught. Along with this, if the roller rides on the pillar portion of the cage, the cage may be damaged.
An object of the present invention is to prevent a cage from being damaged even when a roller bearing provided with a synthetic resin cage is inflated and comes into contact with an outer ring raceway surface during use.

上記課題を解決するために、この発明のころ軸受は、外輪および内輪の軌道面が軸方向に傾斜し、内輪の外周面の前記傾斜した軌道面の小径側に小鍔部が形成され、大径側に大鍔部が形成され、大径側環状部と小径側環状部と両環状部を連結する複数の柱部とからなり、周方向で隣り合う柱部と前記両環状部とで、ころを保持するポケットが形成されている合成樹脂製保持器を有するころ軸受であって、前記保持器は、前記柱部の外径面が前記両環状部の外周面より凹み、前記両環状部の外周面と前記外輪の軌道面との接触で案内されることを特徴とする。   In order to solve the above problems, in the roller bearing of the present invention, the raceway surfaces of the outer ring and the inner ring are inclined in the axial direction, and a small flange portion is formed on the small diameter side of the inclined raceway surface of the outer ring surface of the inner ring. A large collar portion is formed on the radial side, and includes a large-diameter-side annular portion, a small-diameter-side annular portion, and a plurality of column portions that connect both annular portions. A roller bearing having a synthetic resin cage in which pockets for holding rollers are formed, wherein the cage has an outer diameter surface of the column portion recessed from an outer peripheral surface of the annular portions, and the annular portions. It is guided by contact with the outer peripheral surface of the outer ring and the raceway surface of the outer ring.

この発明のころ軸受によれば、保持器が、柱部ではなく、大径側環状部および小径側環状部の外周面と外輪の軌道面との接触により案内される。よって、保持器の柱部が外輪の軌道面と接触せず、外輪の軌道面ところの転動面との間に挟まれることがないため、ころが保持器の柱部に乗り上げることが防止される。
また、前記保持器の大径側環状部および小径側環状部で、外周面と前記外輪の軌道面との間隔を同じか略同じにすることで、保持器外周面の偏摩耗を防止することができる。 According to the roller bearing of the present invention, the cage is guided not by the column portion but by contact between the outer peripheral surface of the large-diameter side annular portion and the small-diameter side annular portion and the raceway surface of the outer ring. Therefore, the pillar portion of the cage does not come into contact with the raceway surface of the outer ring and is not sandwiched between the raceway surfaces of the raceway surface of the outer ring, so that the rollers are prevented from riding on the pillar portion of the cage. The
In addition, by making the distance between the outer circumferential surface and the raceway surface of the outer ring the same or substantially the same in the large-diameter side annular portion and the small-diameter side annular portion of the cage, uneven wear of the cage outer circumferential surface is prevented. Can do.

この発明によれば、合成樹脂製保持器を備えたころ軸受において、使用時に保持器が大きく膨張して外輪軌道面と接触した場合でも、保持器に破損が生じないようにすることができる。   According to the present invention, in a roller bearing provided with a synthetic resin cage, it is possible to prevent the cage from being damaged even when the cage is greatly expanded during use and contacts the outer ring raceway surface.

以下、この発明の実施形態について説明する。
図１に示すように、第１実施形態の円錐ころ軸受は、内輪１、外輪２、円錐状のころ３、および、保持器４からなる。内輪１の外周面の軸方向中央部に、軸方向に傾斜した軌道面１ａが形成されている。内輪１の外周面の軸方向両端部には、軌道面１ａの小径側に小鍔部１１が形成され、大径側に大鍔部１２が形成されている。 Embodiments of the present invention will be described below.
As shown in FIG. 1, the tapered roller bearing of the first embodiment includes an inner ring 1, an outer ring 2, a conical roller 3, and a cage 4. An axially inclined track surface 1 a is formed at the axially central portion of the outer peripheral surface of the inner ring 1. At both ends in the axial direction of the outer peripheral surface of the inner ring 1, a small flange portion 11 is formed on the small diameter side of the raceway surface 1a, and a large flange portion 12 is formed on the large diameter side.

外輪２は、軌道面２ａである内周面全体が軸方向に傾斜している。また、外輪２の軸方向寸法が従来品よりも大きく形成されている。よって、保持器４に保持されているころ３は、外輪２の軌道面２ａの軸方向両端部を除いた軸方向中央部に実質的に接触する。
保持器４は、大径側環状部４１と小径側環状部４２と両環状部４１，４２を連結する柱部４３とからなり、周方向で隣り合う柱部４３と両環状部４１，４２とで、ころ３を保持するポケット４４が形成されている。保持器４の柱部４３の外径面４３ａが、大径側環状部４１および小径側環状部４２の外周面より凹んでいる。 In the outer ring 2, the entire inner peripheral surface which is the raceway surface 2a is inclined in the axial direction. Moreover, the axial direction dimension of the outer ring | wheel 2 is formed larger than the conventional product. Therefore, the roller 3 held by the cage 4 substantially contacts the central portion in the axial direction excluding both axial end portions of the raceway surface 2 a of the outer ring 2.
The cage 4 includes a large-diameter-side annular portion 41, a small-diameter-side annular portion 42, and a column portion 43 that connects both the annular portions 41, 42, and the column portion 43 and the annular portions 41, 42 that are adjacent in the circumferential direction. Thus, a pocket 44 for holding the roller 3 is formed. The outer diameter surface 43 a of the pillar portion 43 of the cage 4 is recessed from the outer peripheral surfaces of the large diameter side annular portion 41 and the small diameter side annular portion 42.

また、保持器４の大径側環状部４１および小径側環状部４２で、外周面と外輪２の軌道面２ａとの間隔を同じか略同じにしている。すなわち、大径側環状部４１および小径側環状部４２の外周面に沿ったラインＬK と、外輪２の軌道面２ａに沿ったラインＬG を平行か略平行にしている。
その結果、柱部４３の外径面４３ａと外輪２の軌道面２ａとの間隔（ラインＬH とＬG との距離）が、大径側環状部４１および小径側環状部４２の外周面と外輪２の軌道面２ａとの間隔（ラインＬK とＬG との距離）より大きくなっている。そのため、保持器４は、大径側環状部４１および小径側環状部４２の外周面が、外輪２の軌道面２ａの軸方向両端部に接触することで案内される。よって、保持器４の柱部４３は、外輪２の軌道面２ａと接触せず、外輪２の軌道面２ａところ３の転動面との間に挟まれることがないため、ころ３が保持器４の柱部４３に乗り上げることが防止される。 Further, in the large-diameter side annular portion 41 and the small-diameter side annular portion 42 of the cage 4, the distance between the outer peripheral surface and the raceway surface 2 a of the outer ring 2 is the same or substantially the same. In other words, a line L K along the outer peripheral surface of the large diameter side annular portion 41 and the small-diameter-side annular portion 42, and substantially parallel or parallel lines L G along the raceway surface 2a of the outer ring 2.
As a result, (the distance between the line L H and L G) distance between the raceway surface 2a of the outer diameter surface 43a and the outer ring 2 of the pillar portion 43, and the outer peripheral surface of the large diameter side annular portion 41 and the small-diameter-side annular portion 42 It is larger than the distance between the raceway surface 2a of the outer ring 2 (the distance between the line L K and L G). Therefore, the retainer 4 is guided by the outer peripheral surfaces of the large-diameter side annular portion 41 and the small-diameter side annular portion 42 coming into contact with both end portions in the axial direction of the raceway surface 2 a of the outer ring 2. Therefore, the pillar portion 43 of the cage 4 does not come into contact with the raceway surface 2a of the outer ring 2 and is not sandwiched between the raceway surface 2a of the outer ring 2 and the rolling surface of 3, so that the roller 3 is retained by the cage. 4 is prevented from riding on the column part 43.

また、保持器４の大径側環状部４１および小径側環状部４２で、外周面と外輪２の内周面２ａとの間隔が同じか略同じになっているため、保持器４の外周面の偏摩耗が防止できる。
さらに、保持器４の柱部４３の外径面４３ａは、小径側環状部４２および大径側環状部４１の外周面より凹んでいる。外径面４３ａの小径側環状部４２側に傾斜面４３ｂが存在し、大径側環状部４１側に傾斜面４３ｃが存在する。また、図２に示すように、柱部４３の大径側環状部４１側には、図３および４に示す合成樹脂製の保持器４と同様に、欠損面４３２が存在する。 Further, the outer circumferential surface of the cage 4 is the same or substantially the same between the outer circumferential surface and the inner circumferential surface 2 a of the outer ring 2 in the large-diameter side annular portion 41 and the small-diameter side annular portion 42 of the cage 4. Can prevent uneven wear.
Further, the outer diameter surface 43 a of the pillar portion 43 of the cage 4 is recessed from the outer peripheral surfaces of the small diameter side annular portion 42 and the large diameter side annular portion 41. The inclined surface 43b exists on the small diameter side annular portion 42 side of the outer diameter surface 43a, and the inclined surface 43c exists on the large diameter side annular portion 41 side. As shown in FIG. 2, a defect surface 432 exists on the large-diameter-side annular portion 41 side of the column portion 43, as in the case of the synthetic resin cage 4 shown in FIGS. 3 and 4.

そして、図１に示すように、保持器４の傾斜面４３ｂと小径側環状部４２の外周面（ラインＬK ）とのなす角度αと、柱部４３の欠損面４３２と大径側環状部４１の外周面（ラインＬK ）とのなす角度βとの関係をα≦βに設定している。また、傾斜面４３ｂの最大外径Ｄ43b は柱部４３の欠損面４３２の径Ｄ432 より小さい。
これにより、保持器４は、図３および４に示す合成樹脂製の保持器４と同様に、軸方向に分割する金型（２枚の型板）を用いた射出成形法で作製することができる。 As shown in FIG. 1, the angle α formed by the inclined surface 43 b of the cage 4 and the outer peripheral surface (line L K ) of the small diameter side annular portion 42, the defect surface 432 of the column portion 43, and the large diameter side annular portion. The relationship between the angle β formed by the outer peripheral surface 41 (line L K ) 41 is set to α ≦ β. Further, the maximum outer diameter D 43b of the inclined surface 43 b is smaller than the diameter D 432 of the missing surface 432 of the column part 43.
Accordingly, the cage 4 can be manufactured by an injection molding method using a mold (two mold plates) divided in the axial direction, like the cage 4 made of synthetic resin shown in FIGS. it can.

第２実施形態の円錐ころ軸受は、図２に示すように、保持器４の柱部４３の内径面４３ｄを第１実施形態の保持器４の内径面４３ｅより径方向内側にずらして、第１実施形態の保持器４よりも柱部４３の厚さを厚くしている。それ以外は第１実施形態の円錐ころ軸受と同じである。これにより、第２実施形態の円錐ころ軸受は、第１実施形態の円錐ころ軸受と比較して保持器４の強度が向上できる効果を有する。   As shown in FIG. 2, the tapered roller bearing of the second embodiment shifts the inner diameter surface 43 d of the pillar portion 43 of the cage 4 to the inner side in the radial direction from the inner diameter surface 43 e of the cage 4 of the first embodiment. The thickness of the column part 43 is made thicker than the cage 4 of one embodiment. Other than that, it is the same as the tapered roller bearing of the first embodiment. Thereby, the tapered roller bearing of 2nd Embodiment has an effect which can improve the intensity | strength of the holder | retainer 4 compared with the tapered roller bearing of 1st Embodiment.

なお、この発明は、外輪および内輪の軌道面が軸方向に傾斜し、内輪の外周面の前記傾斜した軌道面の小径側に小鍔部が形成され、大径側に大鍔部が形成され、大径側環状部と小径側環状部と両環状部を連結する複数の柱部とからなり、周方向で隣り合う柱部と前記両環状部とで、ころを保持するポケットが形成されている合成樹脂製保持器を有するころ軸受であれば、円錐ころ軸受に相当しないころ軸受にも適用できる。   In the present invention, the raceway surfaces of the outer ring and the inner ring are inclined in the axial direction, a small flange portion is formed on the small diameter side of the inclined raceway surface of the inner ring, and a large flange portion is formed on the large diameter side. A large-diameter side annular portion, a small-diameter side annular portion, and a plurality of column portions that connect both annular portions, and a pocket that holds the rollers is formed by the column portions adjacent to each other in the circumferential direction and the both annular portions. If it is a roller bearing having a synthetic resin cage, it can be applied to a roller bearing not corresponding to a tapered roller bearing.
