Description

本発明は、スラストニードル軸受であって、特に、自動車用変速機のメインシャフトに対して、回転自在に支持する為の回転支持部に使用されるスラストニードル軸受に関する。   The present invention relates to a thrust needle bearing, and more particularly to a thrust needle bearing used for a rotation support portion for rotatably supporting a main shaft of an automobile transmission.

例えば自動車用変速機に組み込まれるメインシャフトにギヤを回転可能に支持する回転支持部の構造として、従来から、例えば特許文献１に記載された様な構造が知られている。図５は、特許文献１に記載された構造の１例を示している。この回転支持部の構造は、小径部３１ａおよび大径部３１ｂを有する軸３１と、小径部３１ａの径方向外側に配置される外方部材３２と、小径部３１ａの外径面および外方部材３２の内径面の間に配置されるラジアルころ軸受３３と、大径部３１ｂおよび外方部材３２の端面の間に配置されるスラストころ軸受１１とを備える。   For example, as a structure of a rotation support portion that rotatably supports a gear on a main shaft incorporated in an automobile transmission, for example, a structure as described in, for example, Patent Document 1 is known. FIG. 5 shows an example of the structure described in Patent Document 1. The structure of the rotation support portion includes a shaft 31 having a small-diameter portion 31a and a large-diameter portion 31b, an outer member 32 disposed on the radially outer side of the small-diameter portion 31a, an outer-diameter surface and an outer member of the small-diameter portion 31a. The radial roller bearing 33 disposed between the inner diameter surfaces of the 32 and the thrust roller bearing 11 disposed between the end surfaces of the large diameter portion 31b and the outer member 32 are provided.

ラジアルころ軸受３３は、複数のころ３３ａと、隣接するころ３３ａの間隔を保持する保持器３３ｂとを備え、小径部３１ａの外径面と外方部材３２の内径面とを軌道面とするケージ＆ローラタイプの針状ころ軸受であって、軸３１に負荷されるラジアル荷重を支持する。   The radial roller bearing 33 includes a plurality of rollers 33a and a retainer 33b that holds an interval between adjacent rollers 33a, and a cage having an outer diameter surface of the small diameter portion 31a and an inner diameter surface of the outer member 32 as a raceway surface. This is a & roller type needle roller bearing that supports a radial load applied to the shaft 31.

スラストころ軸受１１は、複数のころ１２と、隣接するころ１２の間隔を保持する保持器１３とを備える。   The thrust roller bearing 11 includes a plurality of rollers 12 and a cage 13 that holds the interval between the adjacent rollers 12.

保持器１３は、環状の部材であって、金属製の平板をプレス加工等によって折り曲げて形成されている。そして、ころ１２を収容する複数のポケット１７が形成されて径方向に延在する柱部１６と、柱部１６の内周に形成される内周鍔部１５とを有する。   The cage 13 is an annular member, and is formed by bending a metal flat plate by pressing or the like. And it has the pillar part 16 in which the several pocket 17 which accommodates the roller 12 is formed, and extends in a radial direction, and the inner peripheral collar part 15 formed in the inner periphery of the pillar part 16. FIG.

内周鍔部１５は、保持器１３の軸方向に延びる円筒部１５ａと、円筒部１５ａの軸方向両端部に径方向外側に屈曲する第１および第２屈曲部１５ｂ，１５ｃとを含み、第１および第２屈曲部１５ｂ，１５ｃは、それぞれ径方向外側に延びる壁面１５ｄ，１５ｅを有している。   The inner peripheral flange 15 includes a cylindrical portion 15a extending in the axial direction of the cage 13, and first and second bent portions 15b and 15c that are bent radially outward at both axial ends of the cylindrical portion 15a. The first and second bent portions 15b and 15c have wall surfaces 15d and 15e extending outward in the radial direction, respectively.

第１屈曲部１５ｂから延びる壁面１５ｄは、所定の長さの直線部分を有し、その先は保持器１３の軸方向に屈曲しながら径方向外側に延び、柱部１６と、さらにその外側に保持器１３の外周に沿って外周鍔部１８とが形成されている。   The wall surface 15d extending from the first bent portion 15b has a straight portion having a predetermined length, and the tip of the wall portion 15d extends radially outward while being bent in the axial direction of the cage 13, and the column portion 16 and further to the outside thereof. An outer peripheral flange 18 is formed along the outer periphery of the cage 13.

第２屈曲部１５ｃから延びる壁面１５ｅは、ポケット１７の手前まで径方向外側に直線的に延びて、先端が保持器１３の軸方向内側、すなわち壁面１５ｄの方向に折り曲げられている。そして、内周鍔部１５の断面形状は、４つの角がそれぞれ所定の曲率を持った略四角形状となっている。   The wall surface 15e extending from the second bent portion 15c linearly extends radially outward to the front of the pocket 17, and the tip is bent in the axial direction inside of the cage 13, that is, in the direction of the wall surface 15d. And the cross-sectional shape of the inner periphery collar part 15 becomes a substantially square shape with four corners each having a predetermined curvature.

そして、スラストころ軸受１１は、大径部３１ｂの端面と第２屈曲部１５ｃから外径方向に延びる壁面１５ｅとが対面し、ラジアルころ軸受３３の保持器３３ｂの軸方向端面と第１屈曲部１５ｂから外径方向に延びる壁面１５ｄの直線部分とが対面するように配置されている。   In the thrust roller bearing 11, the end surface of the large diameter portion 31b and the wall surface 15e extending in the outer diameter direction from the second bent portion 15c face each other, and the axial end surface of the cage 33b of the radial roller bearing 33 and the first bent portion. It arrange | positions so that the linear part of the wall surface 15d extended in the outer diameter direction from 15b may face.

特許文献１では、ラジアルころ軸受３３とスラストころ軸受１１とを図５に示すように配置することによって、軌道輪を省略しても壁面１５ｄの直線部分でラジアルころ軸受３３の軸方向への移動を規制している。また、内周鍔部１５の断面形状を略四角形状として剛性を向上することによって、ラジアルころ軸受３３との接触によって内周鍔部１５が変形するのを防止している。   In Patent Document 1, by arranging the radial roller bearing 33 and the thrust roller bearing 11 as shown in FIG. 5, even if the bearing ring is omitted, the radial roller bearing 33 moves in the axial direction at the straight portion of the wall surface 15d. Is regulated. Further, the inner peripheral flange 15 is prevented from being deformed by contact with the radial roller bearing 33 by improving the rigidity by making the cross-sectional shape of the inner peripheral flange 15 substantially rectangular.

ところで、上記のスラストころ軸受１１では、その保持器１３の内周鍔部１５は、鋼板をバーリング加工や曲げ加工することによって形成される。しかし、形状が複雑であり、材料である鋼板に大きな変形や絞りが施されるため、保持器肉厚が薄くなったり、また、熱処理も軟窒化処理となったりしてしまい、保持器の案内形式が、ラジアルころ軸受の保持器端面で案内される場合や、軸で案内される場合では、その強度の低下が懸念されていた。また、略四角形状のような内周鍔部を成形した後に、バレル研磨や黒染加工処理等の水処理を行なう場合に、内周鍔部に水等の加工液が浸透することとなり、乾燥が不十分な場合には、加工液が内周鍔部内に残ってしまい、その使用時に加工液がにじみ出て、錆や異物等のいわゆるコンタミをもたらす原因となる可能性があった。   By the way, in the thrust roller bearing 11 described above, the inner peripheral flange portion 15 of the cage 13 is formed by burring or bending the steel plate. However, because the shape is complicated and the steel plate, which is the material, is subjected to large deformation and drawing, the cage thickness becomes thin, and the heat treatment also becomes nitrocarburizing treatment, which leads to guidance for the cage. When the type is guided by the cage end face of the radial roller bearing or when it is guided by the shaft, there is a concern about a decrease in strength. In addition, when water treatment such as barrel polishing or black dyeing processing is performed after forming the inner peripheral collar portion such as a substantially square shape, the processing liquid such as water penetrates into the inner peripheral collar portion and is dried. However, if the amount is insufficient, the working fluid remains in the inner peripheral flange, and the working fluid may ooze out during use, which may cause so-called contamination such as rust and foreign matter.
