Description
【０００１】[0001]
本考案は、軸方向の位置決め用の機械要素として広く用いられている止め輪に 関する。 The present invention relates to a snap ring widely used as a mechanical element for axial positioning.
【０００２】[0002]
軸に外嵌された筒体、又は孔に内嵌された軸体を軸長方向に位置決めすべく用 いられる止め輪は、前記軸又は前記孔への後付けが可能であり、設計の自由度が 高いことから、各種の機械装置に広く用いられている。 The snap ring used to position the cylindrical body externally fitted to the shaft or the axial body fitted internally to the hole in the axial direction can be retrofitted to the shaft or the hole, and the degree of freedom in design can be increased. It is widely used in various mechanical devices due to its high cost.
【０００３】 図４は一般的な軸用Ｃ型止め輪の平面図である。図示の如くＣ型止め輪３は、 周方向に均一な矩形断面を有する円環を周方向に適宜の幅を有する開離部3aによ り欠損させ、平面視にてＣ型をなす環状部3bを備えてなる。前記開離部3aを挾ん で対向する前記環状部3bの両端縁には、半径方向外向きに張り出し部が設けてあ り、この張り出し部には、開離部3aの後述する拡幅操作に用いる操作孔3c，3cが 形成してある。FIG. 4 is a plan view of a general C-shaped snap ring for a shaft. As shown in the figure, the C-shaped retaining ring 3 has an annular portion having a uniform rectangular cross section in the circumferential direction, which is cut off by a separating portion 3a having an appropriate width in the circumferential direction to form a C-shaped annular portion in plan view. It is equipped with 3b. At both ends of the annular portion 3b that opposes the opening 3a, protrusions are provided outward in the radial direction, and the protrusions are used for widening operation of the opening 3a described later. The operation holes 3c, 3c to be used are formed.
【０００４】 図５は、軸４に外嵌された筒体５を軸長方向に位置決めする際のＣ型止め輪３ の装着方法の説明図である。装着対象となる軸４の外周には、Ｃ型止め輪３の厚 さと略等しい幅を有する係合溝40が周設してある。Ｃ型止め輪３の装着は、開離 部3aを拡幅せしめて環状部3bを拡径させ、この状態で前記軸４の一側端部から嵌 挿した後、前記係合溝40に整合する位置にて前記拡径を解除する手順により行わ れる。これによりＣ型止め輪３は、図示の如く、環状部3bの内周縁を係合溝40内 に係合させ、外周側を適幅突出させた状態で軸４に係着されたことになり、該軸 ４に外嵌された筒体５は、係合溝40から突出する環状部3bにその一側端面を突き 当てた状態で拘束される。FIG. 5 is an explanatory diagram of a method of mounting the C-shaped retaining ring 3 when positioning the tubular body 5 fitted onto the shaft 4 in the axial direction. An engaging groove 40 having a width substantially equal to the thickness of the C-shaped retaining ring 3 is provided around the outer circumference of the shaft 4 to be mounted. When mounting the C-shaped retaining ring 3, the opening 3a is widened to expand the annular portion 3b, and in this state, the ring 4 is fitted from one end of the shaft 4 and then aligned with the engaging groove 40. It is carried out by the procedure for releasing the diameter expansion at the position. As a result, the C-shaped retaining ring 3 is attached to the shaft 4 in a state where the inner peripheral edge of the annular portion 3b is engaged in the engagement groove 40 and the outer peripheral side is protruded by an appropriate width as shown in the figure. The cylindrical body 5 fitted onto the shaft 4 is constrained with its one end face abutting against the annular portion 3b protruding from the engagement groove 40.
【０００５】 さて、以上の如きＣ型止め輪３の装着に際しては、開離部3aを拡幅させ、この 状態を軸４への嵌挿の間に維持する必要があり、これらのことは一般的に、前記 操作孔3c，3cに作用端を差し込んだプライヤーの操作により行われるが、同一寸 法を有する多数の軸４，４…に対して各別のＣ型止め輪３，３…を装着すること が要求される製造ラインにおいては、装着作業の能率向上のため、図６に示す如 き専用の治具６が用いられることがある。When mounting the C-shaped retaining ring 3 as described above, it is necessary to widen the opening portion 3a and maintain this state during the insertion into the shaft 4. The operation is performed by operating the pliers with the working ends inserted in the operation holes 3c, 3c, but different C-shaped retaining rings 3, 3 ... Are attached to a large number of shafts 4, 4 ,. In a manufacturing line that is required to do so, a dedicated jig 6 as shown in FIG. 6 may be used in order to improve the efficiency of mounting work.
【０００６】 治具６は、軸４への遊嵌が可能な円筒形をなす保持部6aの一側に、先端に向け て外径が縮径されたテーパ部6bを連設した構成となっており、この治具６を用い たＣ型止め輪の装着作業は、保持部6aに多数のＣ型止め輪３，３…を保持させた 治具６をテーパ部6b側から軸４に遊嵌し、１つのＣ型止め輪３をテーパ部6b側に 押出し、該テーパ部6bの傾斜に沿わせて滑動させて、先端縁に整合する係合溝40 内に落とし込む手順にて行われる。The jig 6 has a structure in which a taper portion 6b having an outer diameter reduced toward the tip is continuously provided on one side of a cylindrical holding portion 6a that can be loosely fitted on the shaft 4. In order to mount the C-shaped retaining ring using this jig 6, the jig 6 having a large number of C-shaped retaining rings 3, 3 ... It is carried out by a procedure of fitting, pushing out one C-shaped retaining ring 3 to the taper portion 6b side, sliding it along the inclination of the taper portion 6b, and dropping it into the engaging groove 40 aligned with the tip edge.
【０００７】[0007]
さて、以上の如く装着された軸用のＣ型止め輪３は、一般的には、軸４の外側 に隙間なく嵌合された筒体５の位置決めに用いられるが、前記軸４の外周との間 に適宜の隙間を有して嵌合する筒体５の位置決めに用いられることもある。図７ は、このような位置決め状態を示す側断面図である。位置決め対象となる筒体５ は、軸４を囲繞する筒形のハウジング７に内嵌保持され、軸４の外周との間に隙 間を有しており、前記筒体５の軸長方向への位置決めは、軸４外周の係合溝40に 係合されたＣ型止め輪３にその一側端面を当接せしめて行われている。 Now, the C-shaped retaining ring 3 for the shaft mounted as described above is generally used for positioning the cylindrical body 5 fitted on the outer side of the shaft 4 with no gaps. It may be used to position the cylindrical body 5 fitted with a proper gap between them. FIG. 7 is a side sectional view showing such a positioning state. The tubular body 5 to be positioned is internally fitted and held in a tubular housing 7 surrounding the shaft 4 and has a gap between the outer periphery of the shaft 4 and the tubular body 5 in the axial direction of the tubular body 5. The positioning is performed by contacting one end face of the C-shaped retaining ring 3 engaged with the engagement groove 40 on the outer periphery of the shaft 4 with one end surface thereof.
【０００８】 このような用途においては、筒体５の端面との当接を可能とするため、軸４の 外側に突出する環状部3bの幅寸法が軸４と筒体５との間の隙間寸法を上回ること が必要であり、内外径差が大きい広幅のＣ型止め輪３が用いられる。In such an application, the width of the annular portion 3b protruding to the outside of the shaft 4 is set so that the gap between the shaft 4 and the cylinder 5 can be brought into contact with the end surface of the cylinder 5. It is necessary to exceed the size, and a wide C-shaped retaining ring 3 having a large difference in inner and outer diameters is used.
【０００９】 ところが、この種のＣ型止め輪３においては、軸４への装着に際して広幅の環 状部3bを拡径するために大きい力を必要とし、また、この拡径が環状部3bの塑性 変形を招来し、拡径力の解除後における係合溝40への係合が確実に行われず、筒 体５の確実な位置決めに支障を来す場合があった。However, in this type of C-shaped snap ring 3, a large force is required to expand the wide annular portion 3b when it is mounted on the shaft 4, and this expansion also causes the annular portion 3b to expand. There is a case where plastic deformation is caused, and the engagement with the engagement groove 40 is not reliably performed after the expansion force is released, which hinders the reliable positioning of the cylinder 5.
【００１０】 更に、前記治具６を用いたＣ型止め輪３の装着においては、装着対象となる軸 ４よりも更に大なる外径を有する前記保持部6aへの嵌挿のために、環状部3bに余 分な拡径を強いられることから、広幅のＣ型止め輪３に対しての前記治具６の使 用は難しく、プライヤー等の専用工具を用いた装着に頼らざるを得ず、装着作業 に多大の手間を要する難点があった。Further, when the C-shaped retaining ring 3 is mounted using the jig 6, an annular shape is required for fitting the C-shaped retaining ring 3 into the holding portion 6a having an outer diameter larger than that of the shaft 4 to be mounted. Since the portion 3b is forced to have an excessively large diameter, it is difficult to use the jig 6 for the wide C-shaped retaining ring 3, and it is inevitable to rely on mounting using a dedicated tool such as pliers. However, there was a problem that the mounting work required a lot of work.
【００１１】 なお以上の如き問題は、縮径変形せしめた状態で円孔に内挿され、該円孔に内 嵌された軸体の位置決めのために内周面に周設された係合溝に係着して用いられ る穴用Ｃ型止め輪においても全く同様に生じるものである。The above-mentioned problems are caused by the engagement groove which is inserted into the circular hole in a state of being reduced in diameter and deformed, and is provided around the inner peripheral surface for positioning the shaft body fitted in the circular hole. The same is true for the C-type retaining ring for holes that is used by being attached to the.
【００１２】 本考案は斯かる事情に鑑みてなされたものであり、装着時における拡径又は縮 径に伴う塑性変形の程度を緩和し、広幅であっても十分な拡径又は縮径が可能で あり、治具を用いた能率的な装着をなし得るＣ型止め輪を提供することを目的と する。The present invention has been made in view of such circumstances, and it is possible to reduce the degree of plastic deformation associated with the diameter expansion or the diameter reduction at the time of mounting, and to sufficiently expand or reduce the diameter even if the width is wide. It is an object of the present invention to provide a C-shaped retaining ring that can be efficiently mounted using a jig.

本考案に係る止め輪は、周方向に適宜幅を有する開離部により円環の一部を欠 損させた環状部を備え、該環状部を前記開離部の拡幅又は縮幅を伴って変形させ 、円形断面を有する軸の外側又は孔の内側に挿入し、夫々の周面に係着せしめて 用いる止め輪において、前記環状部の外周縁に開口を有し、半径方向内向きに延 びる複数本の外側スリットと、これらと異なる周方向位置にて前記環状部の内周 縁に開口を有し、半径方向外向きに延びる複数本の内側スリットとを、前記開離 部の両側に夫々軸対称をなして具備することを特徴とする。 A retaining ring according to the present invention comprises an annular portion in which a part of an annulus is cut off by an opening having an appropriate width in the circumferential direction, and the annular portion is expanded or contracted with the opening. In a retaining ring that is deformed and inserted into the outside of a shaft having a circular cross section or inside the hole and fixedly attached to each circumferential surface, the retaining ring has an opening at the outer peripheral edge and extends radially inward. A plurality of outer slits, and a plurality of inner slits that extend outward in the radial direction and that have openings at the inner peripheral edge of the annular portion at different circumferential positions are provided on both sides of the opening. It is characterized in that each of them is provided with axial symmetry.

本考案においては、軸又は孔への装着時における拡径又は縮径に伴う環状部の 変形を、該環状部の外周縁及び内周縁に夫々形成された外側スリット及び内側ス リットの開口幅の増減により吸収し、塑性変形が生じない状態での十分な拡径又 は縮径を許容し、治具を用いた装着を可能とする。 In the present invention, the deformation of the annular portion due to the expansion or contraction of the diameter when mounted on the shaft or the hole is controlled by the opening widths of the outer slit and the inner slit formed on the outer peripheral edge and the inner peripheral edge of the annular portion, respectively. It absorbs due to increase or decrease and allows sufficient diameter expansion or diameter reduction without plastic deformation, enabling mounting using a jig.

以下本考案をその実施例を示す図面に基づいて詳述する。図１は本考案に係る Ｃ型止め輪の平面図である。図示の如くこのＣ型止め輪１は、図４に示す従来の Ｃ型止め輪３と同様、周方向に均一な矩形断面を有する円環を周方向に適宜の幅 を有する開離部1aにより欠損させ、平面視にてＣ型をなす環状部1bを備え、また 開離部1aを挾んで対向する環状部1bの両端縁近傍に夫々操作孔1c，1cを備えてな る。 Hereinafter, the present invention will be described in detail with reference to the drawings showing an embodiment thereof. FIG. 1 is a plan view of a C-shaped retaining ring according to the present invention. As shown in the figure, this C-shaped retaining ring 1 is similar to the conventional C-shaped retaining ring 3 shown in FIG. 4 in that a ring having a uniform rectangular cross section in the circumferential direction is formed by an opening 1a having an appropriate width in the circumferential direction. It is provided with an annular portion 1b which is cut off and has a C-shape in a plan view, and operating holes 1c and 1c are provided in the vicinity of both end edges of the annular portion 1b which face each other across the opening 1a.
【００１６】 さて、本考案に係るＣ型止め輪１の環状部1bには、開離部1aを挾んだ両側に軸 対称をなして並び、外周縁に開口を有して半径方向内向きに延びる複数本の外側 スリット10，10…が形成してあり、また、周方向に互いに相隣する前記外側スリ ット10，10間の夫々に、内周縁に開口を有して半径方向外向きに延びる複数本の 内側スリット11，11…が形成してある。Now, in the annular portion 1b of the C-shaped retaining ring 1 according to the present invention, the annular portion 1b is arranged axially symmetrically on both sides of the separation portion 1a, and has an opening at the outer peripheral edge and is directed radially inward. Are formed with a plurality of outer slits 10, 10, ... Also, each of the outer slits 10, 10 adjacent to each other in the circumferential direction has an opening at the inner peripheral edge thereof and has an outer radial direction. A plurality of inner slits 11 extending in the direction are formed.
【００１７】 図２は、環状部1bの一部拡大図であり、外側スリット10及び内側スリット11の 詳細な形成態様を示している。図示の如く外側スリット10は、環状部1bの外周縁 からの長さＬ1 と、略一定の幅Ｗ1 とを有し、また内側スリット11は、同じく内 周縁からの長さＬ2 と、略一定の幅Ｗ2 とを有しており、これらの先端部には、 夫々の幅Ｗ1 及びＷ2 よりも大なる直径を有する円形のぬすみ孔 10a,11aが貫通 形成してある。FIG. 2 is a partially enlarged view of the annular portion 1b, showing a detailed formation mode of the outer slit 10 and the inner slit 11. As shown, the outer slit 10 has a length L 1 from the outer peripheral edge of the annular portion 1b and a substantially constant width W 1, and the inner slit 11 also has a length L 2 from the inner peripheral edge. They have a substantially constant width W 2 and are formed at their tips with circular recessed holes 10 a, 11 a having a diameter larger than the respective widths W 1 and W 2 .
【００１８】 図３は、環状部1bに拡径又は縮径方向の力を加えた場合に生じる外側スリット 10及び内側スリット11の変形状態を示す説明図である。拡径方向の力が加えられ た場合、図３（ａ）に示す如く、外側スリット10が開口幅を減じ、内側スリット 11が開口幅を増す変形態様を夫々示し、逆に縮径方向の力が加えられた場合、図 ３（ｂ）に示す如く、外側スリット10が開口幅を増し、内側スリット11が開口幅 を減じる変形態様を夫々示す。従って、複数の外側スリット10，10…及び内側ス リット11，11…を周方向に備えた前記環状部1bは、前述の如き変形に伴って大き く拡径又は縮径することができる。FIG. 3 is an explanatory view showing a deformed state of the outer slit 10 and the inner slit 11 which occurs when a force in the diameter expanding or contracting direction is applied to the annular portion 1b. When a force in the diameter expanding direction is applied, as shown in FIG. 3 (a), the outer slit 10 reduces the opening width and the inner slit 11 increases the opening width. 3B, the outer slit 10 increases the opening width and the inner slit 11 decreases the opening width, respectively, as shown in FIG. 3B. Therefore, the annular portion 1b provided with the plurality of outer slits 10, 10, ... And the inner slits 11, 11, ... In the circumferential direction can be greatly expanded or reduced in diameter in accordance with the deformation as described above.
【００１９】 本考案に係るＣ型止め輪１は、従来のＣ型止め輪３と同様、図５又は図６に示 す如く軸４に装着して用いられる。この装着に際し、開離部1aを拡幅せしめて環 状部1bを拡径させた場合、環状部1bの外周縁及び内周縁には、局所的に引張力又 は圧縮力が作用するが、本考案に係るＣ型止め輪１においては、周方向に並設さ れた外側スリット10，10…及び内側スリット11，11…が、夫々の形成部位での引 張力又は圧縮力の作用により、図３（ａ）に示す如く変形することになり、環状 部1bの十分な拡径が許容される。この結果本考案に係るＣ型止め輪１は、図６に 示す如く、装着対象となる軸４よりも大なる外径を有する治具６への嵌挿も可能 であり、該治具６を用いた能率的な装着が可能となる。The C-shaped retaining ring 1 according to the present invention is used by being mounted on the shaft 4 as shown in FIG. 5 or 6 like the conventional C-shaped retaining ring 3. At the time of this mounting, when the open portion 1a is widened and the annular portion 1b is expanded, tensile or compressive force locally acts on the outer peripheral edge and the inner peripheral edge of the annular portion 1b. In the C-shaped retaining ring 1 according to the invention, the outer slits 10, 10 ... And the inner slits 11, 11 ... juxtaposed in the circumferential direction are formed by the action of tensile force or compressive force at the respective forming portions. As shown in FIG. 3 (a), it is deformed, and the diameter of the annular portion 1b is sufficiently expanded. As a result, the C-shaped retaining ring 1 according to the present invention can be fitted and inserted into a jig 6 having an outer diameter larger than that of the shaft 4 to be mounted, as shown in FIG. It is possible to use it efficiently.
【００２０】 なお、外側スリット10の長さＬ1 及び幅Ｗ1 と、内側スリット11の長さＬ2 及 び幅Ｗ2 とは、環状部2bの拡径に伴う変形態様を均一化するため、夫々略同一寸 法とするのがよく、また前記長さＬ1 ，Ｌ2 は、図示の如く、環状部2bの幅方向 に外側スリット10と内側スリット11との重なりが生じるように設定される。また 外側スリット10及び内側スリット11の先端側に形成されたぬすみ孔 10a,11aは、 前述した変形に伴って先端部に生じる応力集中を緩和する作用をなす。Note that the length L 1 and width W 1 of the outer slit 10 and the length L 2 and width W 2 of the inner slit 11 are for uniformizing the deformation mode due to the diameter expansion of the annular portion 2b. , And the lengths L 1 and L 2 are set so that the outer slit 10 and the inner slit 11 overlap each other in the width direction of the annular portion 2b as shown in the drawing. It Further, the recessed holes 10a, 11a formed on the tip side of the outer slit 10 and the inner slit 11 have a function of relieving the stress concentration generated at the tip portions due to the aforementioned deformation.
【００２１】 また、前述の如く軸４に装着されたＣ型止め輪１は、これにより位置決めされ る筒体５（図５参照）を介して作用する軸方向の力に対して所定の強度を有する 必要があるが、前述の如き細幅の外側スリット10及び内側スリット11の形成に伴 う軸方向の力に対する強度低下はわずかであり、問題となる場合は少ない。特に 軸方向の力に対する強度確保が必要な場合には、外側スリット10及び内側スリッ ト11の幅Ｗ1 及びＷ2 を可及的に小さくすることにより対応でき、この場合にお ける環状部1bの拡径量は、外側スリット10及び内側スリット11の形成数を増すこ とにより確保できる。Further, as described above, the C-shaped retaining ring 1 mounted on the shaft 4 has a predetermined strength against the axial force acting via the cylindrical body 5 (see FIG. 5) positioned by the C-shaped retaining ring 1. Although it is necessary to have the strength, the strength reduction with respect to the axial force due to the formation of the outer slit 10 and the inner slit 11 having the narrow width as described above is slight, and there is little problem. Especially when it is necessary to secure the strength against the axial force, it can be dealt with by reducing the widths W 1 and W 2 of the outer slit 10 and the inner slit 11 as much as possible, and in this case, the annular portion 1b. The diameter expansion amount can be secured by increasing the number of outer slits 10 and inner slits 11 formed.
【００２２】 なお本実施例においては、軸用Ｃ型止め輪について説明したが、本考案は、穴 用Ｃ型止め輪においても同様に適用可能であり、図１に示すＣ型止め輪１は、穴 用としてもそのまま使用可能である。更に本考案は、平面視においてＣ型をなす Ｃ型止め輪に限らず、他の平面形状を有する止め輪にも適用できる。In the present embodiment, the C-shaped retaining ring for the shaft has been described, but the present invention can be similarly applied to the C-shaped retaining ring for holes, and the C-shaped retaining ring 1 shown in FIG. It can also be used as is for holes. Furthermore, the present invention is not limited to a C-shaped retaining ring having a C-shape in plan view, but can be applied to a retaining ring having another planar shape.
【００２３】[0023]
以上詳述した如く本考案に係る止め輪においては、環状部の外周縁及び内周縁 に夫々開口を有して形成された外側スリット及び内側スリットが変形し、軸又は 孔への装着に際しての環状部の拡径又は縮径を吸収するから、塑性変形が生じな い状態での十分な拡径又は縮径が許容され、広幅であっても十分な拡径又は縮径 が可能であり、治具を用いた能率的な装着を確実になし得る等、本考案は優れた 効果を奏する。 As described above in detail, in the retaining ring according to the present invention, the outer slit and the inner slit, which have openings at the outer peripheral edge and the inner peripheral edge of the annular portion, are deformed, and the annular ring when mounted on the shaft or the hole is deformed. Since it absorbs the expansion or contraction of the diameter of the part, sufficient expansion or contraction of the diameter is allowed in the state where plastic deformation does not occur, and even if it is wide, sufficient expansion or contraction is possible. The present invention has excellent effects such as efficient mounting using a tool.
