【考案の詳細な説明】
この考案は、円筒ころ軸受用ニラ割保持器、特に内外輪
が共にニラ割の円筒ころ軸受の保持器を半円形の保持部
材を２個合わせて構成したものに関する。[Detailed Description of the Invention] This invention relates to a split cage for a cylindrical roller bearing, particularly a cage for a cylindrical roller bearing with split inner and outer rings, which is constructed by combining two semicircular holding members.
現在、ニラ割型の円筒ころ軸受用もみ抜き保持器はポケ
ット柱部にて軸方向に分割し、半円形の保持部材２個を
ボルト等で締結して一体とするタイプが一般的に採用さ
れており、ボルト等による固定はそれだけスペースが必
要で、ころを多く使用できないため軸受の負荷容量低下
の原因となっている。Currently, machined cages for split-type cylindrical roller bearings are generally split in the axial direction at the pocket column, and then integrated into one by connecting two semicircular holding members with bolts, etc. Fixing with bolts, etc. requires a corresponding amount of space, which prevents the use of many rollers, which causes a reduction in the bearing's load capacity.
また、タップ加工、ボルト挿入部の加工及び固定用ボル
トが必要で、これらの加工はかなり複雑で加工上の難点
となっていた。In addition, tapping, processing of bolt insertion parts, and fixing bolts are required, and these processes are quite complicated and pose difficulties in processing.
この考案は、従来例の上記の欠点に鑑みこれを改良した
もので、特に自然側方式の軌道輪の開発による製作上の
有利を更に活かすための工夫を提供せんとするものであ
る。This invention is an improvement of the conventional example in view of the above-mentioned drawbacks, and particularly aims to provide an ingenuity to further utilize the manufacturing advantages of the development of the natural side type bearing ring.
以下この考案の構成を第１図乃至第７図に従って説明す
ると次の通りである。The structure of this invention will be explained below with reference to FIGS. 1 to 7.
第１図及び第２図において、１は軸方向に自然割の円筒
ころ軸受内輪、２は同軸方向に自然割の外輪、３は円筒
ころ、４は保持器、５及び６は締付輪である。In Figures 1 and 2, 1 is a naturally split cylindrical roller bearing inner ring in the axial direction, 2 is a naturally split outer ring in the coaxial direction, 3 is a cylindrical roller, 4 is a cage, and 5 and 6 are tightening rings. be.
そして、内輪１及び外輪２は研磨で最終仕上げをした後
（軸方向に自然割され、保持器４は軸方向に切り割った
半円形の保持部材２個で以って構成される。After the inner ring 1 and the outer ring 2 are given a final finish by polishing (they are naturally split in the axial direction, the cage 4 is constituted by two semicircular holding members cut in the axial direction).
尚、内外輪１，２の自然割の割り口部（内外径側、軌道
面側）は充分にパリ取りをしておくことが必要である。Incidentally, it is necessary to sufficiently remove burr from the naturally split portions of the inner and outer rings 1 and 2 (inner and outer diameter sides, raceway surface sides).
上記内輪１、外輪２及び保持器４の割り口の方向は、内
輪は同一方向、外輪は凸と凹又は凹と凸とし、組合わせ
た時、割り口が互にずれない様にされる。The directions of the split ends of the inner ring 1, outer ring 2, and retainer 4 are such that the inner ring faces in the same direction and the outer rings are convex and concave or concave and convex so that the split ends do not deviate from each other when combined.
又、軸受内輪１の自然割部Ｉには内輪自然側稜破断片面
に薄い高分子材料の緩衝材を接着剤等で以って接着し、
接着後締付輪で固定する。Further, in the natural split portion I of the bearing inner ring 1, a thin polymer material cushioning material is adhered to the fractured surface of the inner ring natural side with an adhesive or the like.
After gluing, secure with a tightening ring.
保持器４は半円形の一対の保持部材８と９からなり、そ
の合わせ部１４，１５はポケットの中央部とする。The retainer 4 consists of a pair of semicircular retaining members 8 and 9, and their mating parts 14 and 15 are at the center of the pocket.
ところで、本考案の保持器は保持器外径部が、外輪内径
部にて案内される外輪案内形式にて適用されるもので、
外輪及び保持器は共に軸方向自然割り時及び切断時、変
形が生じ、自然割り後及び切断後の形状は共に半楕円状
となる。By the way, the cage of the present invention is applied in an outer ring guided type in which the outer diameter part of the cage is guided by the inner diameter part of the outer ring.
Both the outer ring and the retainer are deformed when they are naturally split in the axial direction and when they are cut, and both have a semi-elliptical shape after natural splitting and after cutting.
従って夫々を合わせた状態では特に外輪内径の合わせ部
に取付誤差や荷重の負荷に起因する段差が生じる可能性
が犬である。Therefore, when they are combined, there is a high possibility that a step may occur due to installation error or load, especially at the joint portion of the inner diameter of the outer ring.
本考案はこの外輪の段差部に半円形の保持部材の合わせ
部の先端が干渉するのを防ぐため、保持器４０半円形の
一対の保持部材８，９の合わせ部の外径に逃げのための
円弧状の窪み１６を設け、外輪の段差部に合わせ部が衝
突するのを防ぎ、保持器を円滑に回転する様になしたも
のである。In order to prevent the tips of the mating parts of the semicircular holding members from interfering with the stepped part of the outer ring, the present invention provides relief at the outer diameter of the mating parts of the pair of semicircular holding members 8 and 9 of the retainer 40. An arc-shaped recess 16 is provided to prevent the mating portion from colliding with the stepped portion of the outer ring, and to allow the retainer to rotate smoothly.
又、他のポケットの複数個の中央部に同様の円弧形状の
切欠１７が潤滑性能の向上の目的で設けられている。Further, similar circular arc-shaped notches 17 are provided in the central portions of a plurality of other pockets for the purpose of improving lubrication performance.
第３図以下は、この考案に係る保持器のみの詳細を説明
するための図面である。FIG. 3 and subsequent drawings are drawings for explaining the details of only the cage according to this invention.
第３図及び第４図で明らかなように、保持器４は半円形
の一対の保持部材８と９からなり、その円周方向には等
間隔に複数個のポケット１０が存在する。As is clear from FIGS. 3 and 4, the retainer 4 consists of a pair of semicircular retaining members 8 and 9, and a plurality of pockets 10 are present at equal intervals in the circumferential direction.
保持部材８．９は環状部とそれに続く軸方向に延びた柱
部１２からなる半円形のくし形基部を有し、柱部１２間
のポケット１０は当初軸方向の一方に向って開口し、こ
の開口は半円形の側板１１を柱部１２を貫通する鋲１３
で固定することによって蓋される。The retaining element 8.9 has a semicircular comb-shaped base consisting of an annular part followed by an axially extending post 12, the pocket 10 between the posts 12 being initially open in one axial direction; This opening is formed by a stud 13 that passes through the semicircular side plate 11 through the pillar portion 12.
It is covered by fixing it with.

１ａ、１１ａと８ａ 、９ａ間にスキマｔを形成させて
おく、上記合わせ部の位置は、既に述べた如く必ずポケ
ット１０の中央部に位置され、かつ、１８０度に対称的
に位置せしめられている。At the joining part 14-15 of the two semicircular holding members 8 and 9, side edges 11a, 11a, 8a, and 9a are left, and both side edges 1
The position of the above-mentioned joining part, which forms the gap t between 1a, 11a and 8a, 9a, is always located at the center of the pocket 10, as described above, and is symmetrically located at 180 degrees. There is.
尚、第５図、第６図及び第７図は保持器４０合わせ部１
４，１５０詳細を示す図面で、第５図は横から見た図面

4,150 details, FIG. 5 is a side view, FIG. 6 is a top view, and FIG. 7 is a three-dimensional view.
第５図に示す如く、ポケットスキマ２ａと側縁１１ａ、
１１ａ及び８ａ 、９ａのスキマｔはｔ ＞ ２ ａと
する。As shown in FIG. 5, the pocket gap 2a and the side edge 11a,
The clearance t of 11a, 8a, and 9a is t>2a.
これによって、保持部材γ、８０合わせ部は運転時にこ
ろにより分離され、保持部材７，８０合わせ部は直接接
触しないようになされている。As a result, the mating portions of the holding members γ and 80 are separated by the rollers during operation, and the mating portions of the holding members 7 and 80 are prevented from coming into direct contact.
上記、保持部材８９０合わせ部１４，１５をポケット１

っかからず）に案内され得る。As explained above, this invention is a machined cage for a split cylindrical roller bearing that is guided by a split raceway ring, which has annular parts on both sides and is spaced evenly around the circumference between the two layered parts. A column extending in the axial direction is provided at the position, a pocket for accommodating the cylindrical roller is provided between each column, and the column and the side edge The recesses formed by the recesses are provided facing each other, and the cylindrical roller is held by both recesses, and the added dimension of the depth of the above-mentioned recesses is set to the cylindrical roller so that the side edges do not interfere with each other during use. Since the diameter of the retainer is smaller than the diameter of the retainer, and the outer diameter of the mating portion of both retaining members is provided with a recess that serves as a relief, when the outer diameter of the cage is guided by the inner diameter of the outer ring, it will not be split into half. Even if the inner diameter surface of the outer ring is semi-elliptical and misaligned, since the outer diameter portion of the divided end surfaces of both holding members is recessed, it will not collide with the inner diameter stepped portion of the split end surface of the outer ring. You can be guided smoothly (without getting caught).
そして、半円形状に二分割された保持部材の合せ部に側

で支障なく阻止させ得る。By providing a side edge at the joining part of the semicircularly divided holding member, the cylindrical roller inserted into this joining part can be the same cylindrical roller as the other parts, and this cylindrical roller can be inserted into the joining part. The axial movement of the rollers can be prevented without any problem by the side edges of both of the holding members.
筐た、両保持部材の側縁間のスキマはポケットスキマよ
りも犬としであるため、使用中、両保持部材の分割端面
同志が衝突し合うことがない。Since the gap between the side edges of the housing and both holding members is narrower than the pocket gap, the divided end faces of both holding members do not collide with each other during use.
