図１および図２において、１０はころ軸受用溶接保持器全体を示す。１１は帯状鋼板、２０はポケット孔、２１はポケット孔２０の円周方向両側の柱部、２２、２３はポケット孔２０の軸方向両側の耳部、２４、２５は溶接部である。   1 and 2, reference numeral 10 denotes an entire roller bearing welded cage. 11 is a strip-shaped steel plate, 20 is a pocket hole, 21 is a column part on both sides in the circumferential direction of the pocket hole 20, 22 and 23 are ears on both sides in the axial direction of the pocket hole 20, and 24 and 25 are welded parts.

溶接保持器１０は、円周方向に複数のポケット孔２０を有する一枚の帯状鋼板１１を環状に丸めその円周方向の両端部を突合せ溶接して構成されている。各ポケット孔２０は、円周方向両側の柱部２１によって円周方向に仕切られている。複数のポケット孔２０のうち、一つのポケット孔２０を形成する耳部２２、２３に帯状鋼板１１の両端部の突合せ溶接部２４、２５が位置する。   The welded cage 10 is configured by rounding one strip-shaped steel plate 11 having a plurality of pocket holes 20 in the circumferential direction into an annular shape and butt-welding both ends in the circumferential direction. Each pocket hole 20 is partitioned in the circumferential direction by column portions 21 on both sides in the circumferential direction. Of the plurality of pocket holes 20, the butt welds 24, 25 at both ends of the belt-shaped steel plate 11 are located at the ears 22, 23 forming one pocket hole 20.

ポケット孔２０は、円周方向両側の柱部２１と軸方向両側の耳部２２、２３とで囲まれた平面視矩形形状（図２）をなしている。柱部２１は円周方向に一定幅で軸方向に延びる部分であり、耳部２２、２３は軸方向に一定幅で円周方向に延びる部分である。   The pocket hole 20 has a rectangular shape in plan view (FIG. 2) surrounded by column portions 21 on both sides in the circumferential direction and ear portions 22 and 23 on both sides in the axial direction. The column portion 21 is a portion extending in the axial direction with a constant width in the circumferential direction, and the ear portions 22 and 23 are portions extending in the circumferential direction with a constant width in the axial direction.

溶接保持器１０は、幅が一定で所定長さに切断した帯状鋼板１１を円周方向に環状に丸めて作られ、円周方向の両端部が突合せ溶接されるものであり、その両端部が突合せ溶接されて溶接部２４、２５が形成される。これら溶接部２４、２５は、円周方向に複数ある耳部２２、２３のうち、一つの耳部２２、２３の円周方向の中間に設けられている。溶接部２４、２５は、帯状鋼板１１の板厚分だけ、しかも耳部２２、２３と同じ幅分だけ、帯状鋼板１１を溶かした部分である。溶接部２４、２５を有する耳部２２、２３の両側面には、溶接部２４、２５を含む円周方向両側にかけて凹み部３０、３１が形成されている。この凹み部３０、３１は、帯状鋼板１１の板厚方向に貫通しており、溶接保持器１０の軸方向に凹んでいる。凹み部３０、３１を挟んで円周方向両側には案内面４０が形成され、この案内面４０によってころが回転可能に保持される。案内面４０は、柱部２１とともにポケット孔２０を構成する部分である。凹み部３０、３１の円周方向両側には、傾斜した段部４１、４２を有し、この段部４１、４２に後述する溶接ビード３２、３３がかからないように、凹み部３０、３１は、溶接ビード３２、３３の幅の３倍程度の幅を有する。   The welded cage 10 is made by rolling a strip-shaped steel plate 11 having a constant width and cut into a predetermined length into a ring shape in the circumferential direction, and both ends in the circumferential direction are butt welded. Butt welds 24 and 25 are formed by butt welding. These welding parts 24 and 25 are provided in the middle of the circumferential direction of one ear | edge part 22 and 23 among the several ear | edge parts 22 and 23 in the circumferential direction. The welded portions 24 and 25 are portions where the strip-shaped steel plate 11 is melted by the thickness of the strip-shaped steel plate 11 and by the same width as the ear portions 22 and 23. On both side surfaces of the ear portions 22 and 23 having the welded portions 24 and 25, recessed portions 30 and 31 are formed on both sides in the circumferential direction including the welded portions 24 and 25. The recessed portions 30 and 31 penetrate in the plate thickness direction of the belt-shaped steel plate 11 and are recessed in the axial direction of the welded cage 10. Guide surfaces 40 are formed on both sides in the circumferential direction across the recesses 30 and 31, and the rollers are rotatably held by the guide surfaces 40. The guide surface 40 is a part that constitutes the pocket hole 20 together with the column part 21. On both sides in the circumferential direction of the recesses 30 and 31, there are inclined step portions 41 and 42, and the recess portions 30 and 31 It has a width about three times the width of the weld beads 32, 33.

各溶接部２４、２５の溶接保持器１０の軸方向両側には、突合せ溶接したときにはみ出た溶接ビード３２、３３が形成されている。溶接ビード３２、３３は、各溶接部２４、２５の両側面を塞ぐような形で設けられる。すなわち、溶接ビード３２、３３は、各溶接部２４、２５の円周方向の幅より大きめの幅でもって帯状鋼板１１の板厚方向に貫通して設けられている（図３）。溶接ビード３２、３３は、断面半円形状の肉盛であり、溶接保持器１０の軸方向において、凹み部３０、３１内に位置し、ポケット孔２０内へ突出していない。よって、ポケット孔２０に回転可能に保持されるころに対し、溶接ビード３２、３３が接触する可能性が無い。溶接ビート３２、３３がころの収納を阻害しないとともに、回転中のころに接触しない。   On the both sides in the axial direction of the weld cage 10 of the welded portions 24 and 25, weld beads 32 and 33 that protrude when butt welding is formed. The weld beads 32 and 33 are provided so as to close both side surfaces of the welded portions 24 and 25. That is, the weld beads 32 and 33 are provided so as to penetrate in the thickness direction of the strip steel plate 11 with a width larger than the circumferential width of the welded portions 24 and 25 (FIG. 3). The weld beads 32 and 33 are built up with a semicircular cross section, and are positioned in the recessed portions 30 and 31 in the axial direction of the welded cage 10 and do not protrude into the pocket hole 20. Therefore, there is no possibility that the weld beads 32 and 33 come into contact with the rollers rotatably held in the pocket holes 20. The welding beats 32 and 33 do not hinder the storage of the rollers and do not contact the rotating rollers.

凹み部３０、３１は、溶接ビード３２、３３を含む円周方向両側に渡って形成され、段部４１、４２に溶接ビード３２、３３がかかっていないので、溶接保持器１０を円周方向に分断させようとする力が、溶接ビード３２、３３に集中しない。この結果、溶接保持器１０の分断を防ぐことができる。   The recessed portions 30 and 31 are formed on both sides in the circumferential direction including the weld beads 32 and 33, and the weld beads 32 and 33 are not applied to the step portions 41 and 42. The force to be divided is not concentrated on the weld beads 32 and 33. As a result, it is possible to prevent the welding cage 10 from being divided.

次に溶接保持器１０の製造方法を説明する。帯状鋼板１１にプレス加工を施し溶接保持器１０の展開平面を作る。帯状鋼板１１の材料としては、例えば、成形性に優れたＳＰＣ帯状鋼材を用いることができる。   Next, a method for manufacturing the welded cage 10 will be described. The belt-shaped steel plate 11 is subjected to press working to create a development plane of the welded cage 10. As a material of the strip steel plate 11, for example, an SPC strip steel material excellent in formability can be used.

溶接保持器１０の展開平面を作るのに、プレス金型が使用され、プレス金型によって、複数のポケット２０、凹み部３０、３１、円周方向の両端が同時に成形される。すなわち、材料の打ち抜きと材料の切断が同時に行われる。   A press die is used to create a development plane of the welded cage 10, and a plurality of pockets 20, recesses 30 and 31, and both ends in the circumferential direction are simultaneously formed by the press die. That is, material punching and material cutting are performed simultaneously.

後に行われる突合せ溶接において、帯状鋼板１１の両端部が溶け込むので、帯状鋼板１１は、溶接前においては、その両端部に溶接しろを必要とする。そのため、帯状鋼板１１は、実際の溶接保持器の円周方向長さよりも溶接しろ分だけ長く切断されている。帯状鋼板１１は、その両端部が突合わされて溶接される結果、溶接後においては、帯状鋼板１１の円周方向の長さは、その溶接部を含めて規定の円周方向長さとなる。   In the butt welding performed later, both end portions of the strip-shaped steel plate 11 are melted. Therefore, the strip-shaped steel plate 11 requires a welding margin at both end portions before welding. Therefore, the strip steel plate 11 is cut longer than the actual circumferential length of the welded cage by the welding margin. As a result of the end portions of the belt-shaped steel plate 11 being abutted and welded, the length of the strip-shaped steel plate 11 in the circumferential direction after welding is the prescribed circumferential length including the welded portion.

溶接工程では、所定長さに切断した帯状鋼板１１を環状に丸めるとともに、両端部を突合わせた状態にし、この突合わせた部分に高電流を流して溶接を行う。この溶接により両端部間が溶け込んで接続される。この溶接工程により溶けた材料は、帯状鋼板１１の板厚方向および幅方向にはみ出す。幅方向にはみ出すことによって、溶接保持器１０の軸方向両側面に溶接ビード３２、３３が形成される。この溶接ビード３２、３３は、溶接保持器１０の円周方向の幅を持って、帯状鋼板１１の板厚方向に貫通して形成される。しかも、断面半円形状の肉盛を有する。溶接ビード３２、３３は、溶接保持器１０の軸方向において凹み部３０、３１内に位置し、ポケット孔２０内へ突出していない。帯状鋼板１１の板厚方向にはみ出た肉盛は、グラインダー等で除去される。溶接方法は、上記以外の公知の溶接方法でも実施することができる。   In the welding process, the strip-shaped steel plate 11 cut to a predetermined length is rolled into an annular shape, and both ends are brought into a butted state, and a high current is passed through the joined portion to perform welding. By this welding, both ends are melted and connected. The material melted by this welding process protrudes in the plate thickness direction and the width direction of the strip steel plate 11. By protruding in the width direction, weld beads 32 and 33 are formed on both axial sides of the weld cage 10. The weld beads 32 and 33 have a width in the circumferential direction of the weld cage 10 and are formed so as to penetrate in the plate thickness direction of the strip steel plate 11. Moreover, it has an overlay with a semicircular cross section. The weld beads 32 and 33 are located in the recessed portions 30 and 31 in the axial direction of the weld cage 10 and do not protrude into the pocket hole 20. The build-up that protrudes in the thickness direction of the strip-shaped steel plate 11 is removed by a grinder or the like. The welding method can also be carried out by a known welding method other than the above.

本発明はこうした実施形態に何等限定されるものではなく、本発明の要旨を逸脱しない範囲において、種々なる態様で実施し得ることは勿論である。   The present invention is not limited to these embodiments, and can of course be implemented in various modes without departing from the gist of the present invention.

上述した実施形態として、凹み部３０、３１は、円周方向にまっすぐな平面を有する。他の実施形態として、凹み部３０、３１は、円周方向に湾曲した曲面を有しても良い。この曲面は、溶接ビード３２、３３を中心に円周方向両側へ行くに従って、凹み深さが漸減する形でも良い。   As embodiment mentioned above, the recessed parts 30 and 31 have a plane straight in the circumferential direction. As another embodiment, the recessed portions 30 and 31 may have curved surfaces that are curved in the circumferential direction. This curved surface may have a shape in which the dent depth gradually decreases as it goes to both sides in the circumferential direction with the weld beads 32 and 33 as the center.

上述した溶接保持器１０は、針状ころ軸受用溶接保持器に限らず、円筒ころ軸受用溶接保持器にも適用できる。   The above-described welded cage 10 is not limited to a needle roller bearing welded cage but can be applied to a cylindrical roller bearing welded cage.
