Description

【０００１】
【発明の属する技術分野】
本発明は、側輪が周方向でころの範囲となる限定部分で、ころの両端面の凹所の中に向けて圧縮変形されて形成される保持突起を有する、両端面に凹所が形成されたころのためのころ用板金製保持器に関する。
【０００２】
【従来の技術】
米国特許第３２０５０２９号明細書で既に、両端面に凹所が形成されたころに対する保持突起を備えている筒状板金製保持器が知られている。その保持器は筒部材を切断して製造され、そのポケットを打ち抜き加工した後でころが嵌め込まれる。その保持器の側輪の所定部分が、軸方向に作用する圧縮工具によってころの両端面にある凹所の中に向けて圧縮変形され、これによってころが保持器から抜け落ちることを阻止する保持突起（かみ合い結合）が形成される。筒形をなしているのでウェブ（隣接せる二つのポケット間に位置し両側輪を連結している部分）と同じ直径上に位置する側輪から保持突起が形成されることによって、保持器は複数のころの中心を通る円上に位置するようになり、これによって良好な案内作用が得られる。
【０００３】
保持器のより高い安定性が必要とされるか、あるいは内輪の鍔における案内が望まれるとき、保持器の形状を筒形ではなく、断面形状をＬ形あるいはＵ形にしなければならない。この構造の場合、側輪の径方向に延びる環状板部分の形状に影響を与えずに保持突起を形成することはできない。更にまた保持器全体が変形し、これによって軸受における不十分な案内が生じてしまうという虞れがある。
【０００４】
【発明が解決しようとする課題】
本発明の課題は、冒頭に述べた形式の板金製保持器において、側輪に径方向にい延びる環状板部分が存在している場合に、保持器が変形する虞れなしに保持突起を形成することができるようにすることにある。
【０００５】
【課題を解決するための手段及び発明の効果】
この課題は本発明に基づいて、断面形状がＬ状に形成されている少なくとも片側の側輪の径方向に延びる環状板部分に、上記周方向での限定部分でほぼ円周方向に延びる分離個所がスリットとして、保持突起に径方向で隣接した位置に形成され、このスリットによって保持突起が上記限定部分で環状板部分から分離されており、周方向に延びるスリットが周方向にてころの凹所の範囲内に形成されており、側輪の部分であって軸方向に延びる円筒状部分が上記周方向での限定部分でころの端面へ向けて軸方向に圧縮変形されることにより保持突起が形成されていることによって解決される。
【０００６】
側輪の径方向に延びる環状板部分から変形個所が分離されていることによって、保持突起を軸方向に圧縮変形加工する際も側輪は形状が安定し、この径方向に延びる環状板部分に軸方向力は全く作用しない。この利点は保持器全体に影響を及ぼし、これは特にその円形形状を維持する。
【０００７】
【発明の実施の形態】
以下、添付図面に示した実施形態を参照して本発明を詳細に説明する。
【０００８】
図１及びズ２に示されている板金製の保持器は、両側の側輪１と両側輪１間に位置するウェブ２とを有している。片側の側輪１は断面形状がＬ形をなし、径方向に延びる環状板部分４と軸方向に延びる円筒状部分３を有している。ポケットの中に嵌め込まれたころ５は両端面に凹所６を有し、これらの凹所６の中に保持突起７が嵌り込んで、ころ５の保持器からの抜け落ちを阻止している。
【０００９】
上記保持突起７は、圧縮変形工具（図示せず）によって側輪１の軸方向に延びる円筒状部分３を軸方向に圧縮変形して形成される。
【００１０】
径方向で上記保持突起７に続いて位置し円周方向において少なくとも該保持突起７の範囲にわたり延びるスリット８は、保持突起７を側輪１の径方向に延びる環状板部分４から上記範囲で分離し、上記軸方向の圧縮変形により保持突起７が形成される際に環状板部分４が一緒に変形することを防止する。更にスリット８は、それが軸方向に延びる円筒状部分３の内径位置まで達して、径方向に延びる環状板部分４の範囲でも保持突起７が板金厚さより厚くならないように位置づけられている。

BACKGROUND OF THE INVENTION
The present invention is a limited portion in which the side wheel is in the range of the roller in the circumferential direction , and has a holding projection formed by being compressed and deformed into the recess on both end surfaces of the roller, and the recess is formed on both end surfaces. The present invention relates to a roller sheet metal retainer for a rolled roller.
[0002]
[Prior art]
U.S. Pat. No. 3,050,029 already discloses a cylindrical sheet metal cage provided with holding projections for rollers in which recesses are formed on both end faces. The cage is manufactured by cutting a cylindrical member, and the roller is fitted after the pocket is punched. A retaining protrusion that prevents a predetermined portion of the side ring of the cage from being compressed and deformed into a recess on both end faces of the roller by a compression tool acting in the axial direction, thereby preventing the roller from falling off the cage. (Mesh joint) is formed. Since it has a cylindrical shape, a plurality of cages are formed by forming a holding projection from a side ring that is located on the same diameter as the web (a portion that is located between two adjacent pockets and that connects both side wheels). It is located on a circle passing through the center of the roller, and a good guiding action is thereby obtained.
[0003]
When higher stability of the cage is required or guidance on the inner ring collar is desired, the cage shape must be L-shaped or U-shaped instead of cylindrical. In the case of this structure, the holding projection cannot be formed without affecting the shape of the annular plate portion extending in the radial direction of the side wheel. Furthermore, the entire cage may be deformed, which may cause insufficient guidance in the bearing.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to form a holding projection in a sheet metal cage of the type described at the beginning without fear of deformation of the cage when an annular plate portion extending in the radial direction is present on the side wheel. Is to be able to do that.
[0005]
[Means for Solving the Problems and Effects of the Invention]
This object is based on the present invention, in that an annular plate portion extending in the radial direction of at least one side wheel having a cross-sectional shape formed in an L shape is separated into a separation portion extending in a substantially circumferential direction by the limited portion in the circumferential direction. as but a slit, formed in adjacent positions in the radial direction in the holding projections, the recesses of the roller and the holding projections by the slits is separated from the annular plate portion in the limited portion, a slit extending in the circumferential direction at the circumferential direction are formed within the range of, the holding projections by Rukoto is compressed and deformed in the axial direction toward the cylindrical portion extending axially a portion of the side wheels to the end face of the roller limiting portion in the circumferential direction It is solved by being formed.
[0006]
Since the deformed portion is separated from the annular plate portion extending in the radial direction of the side wheel, the shape of the side wheel is stable even when the holding projection is compressed and deformed in the axial direction. No axial force acts at all. This advantage affects the entire cage, which in particular maintains its circular shape.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to embodiments shown in the accompanying drawings.
[0008]
The sheet metal retainer shown in FIGS. 1 and 2 has a side wheel 1 on both sides and a web 2 positioned between the side wheels 1. The side wheel 1 on one side has an L-shaped cross section, and has an annular plate portion 4 extending in the radial direction and a cylindrical portion 3 extending in the axial direction. The rollers 5 fitted in the pockets have recesses 6 at both end faces, and holding projections 7 are fitted in these recesses 6 to prevent the rollers 5 from falling out of the cage.
[0009]
The holding protrusion 7 is formed by compressively deforming the cylindrical portion 3 extending in the axial direction of the side wheel 1 in the axial direction by a compression deformation tool (not shown).
[0010]
The slit 8 that is located in the radial direction following the holding projection 7 and extends in the circumferential direction over at least the range of the holding projection 7 separates the holding projection 7 from the annular plate portion 4 extending in the radial direction of the side wheel 1 in the above range. Then, the annular plate portion 4 is prevented from being deformed together when the holding projection 7 is formed by the axial compressive deformation. Furthermore, the slit 8 reaches the inner diameter position of the cylindrical portion 3 extending in the axial direction, and the holding projection 7 is positioned so as not to be thicker than the thickness of the sheet metal even in the range of the annular plate portion 4 extending in the radial direction.
