Description

本発明は、ころ軸受用溶接保持器に関する。   The present invention relates to a roller bearing welded cage.

従来の溶接保持器は、例えば図３に示すものがある（特許文献１）。１００は帯状鋼板、１０１はポケット孔、１０２はポケット孔１０１の円周方向両側の柱部、１０６、１０７はポケット孔１０１の軸方向両側の第１環状部および第２環状部、１０８、１０９は溶接部、１１０、１１１は溶接ビードである。   For example, a conventional welding cage is shown in FIG. 3 (Patent Document 1). 100 is a strip steel plate, 101 is a pocket hole, 102 is a pillar portion on both sides in the circumferential direction of the pocket hole 101, 106 and 107 are first and second annular portions on both axial sides of the pocket hole 101, and 108 and 109 are The welds 110 and 111 are weld beads.

この溶接保持器は、幅が一定で所定の長さに切断した帯状鋼板１００を環状に丸めて作られる。溶接保持器は、円周方向に複数の転動体収納用のポケット孔１０１を有し、複数のポケット孔１０１のうち、一つのポケット孔１０１を構成する軸方向両側の第１環状部１０６および第２環状部１０７に、前記一つのポケット孔１０１の円周方向の中間で、帯状鋼板１００の両端部を設け、この両端部を突合せ溶接することによって両端部間に溶接部１０８、１０９が形成されている。   This welded cage is made by rolling a strip-shaped steel plate 100 having a constant width and cut into a predetermined length into an annular shape. The welding cage has a plurality of pocket holes 101 for accommodating rolling elements in the circumferential direction, and among the plurality of pocket holes 101, the first annular portions 106 and the first annular portions 106 on both sides in the axial direction constituting one pocket hole 101. Two end portions of the strip-shaped steel plate 100 are provided in the two annular portions 107 in the middle of the circumferential direction of the one pocket hole 101, and welded portions 108 and 109 are formed between the both end portions by butt welding the both end portions. ing.

こうして作られた溶接保持器を、円筒ころとともに外輪および内輪間へ挿入して使用すると、円筒ころの進み遅れによって溶接保持器を分断しようとする引っ張り荷重が円周方向に働く。第１環状部１０６および第２環状部１０７に比べて溶接部１０８、１０９の方が強度的に弱いため、溶接部１０８、１０９で分断しやすい。   When the welded cage made in this way is inserted between the outer ring and the inner ring together with the cylindrical roller and used, a tensile load that attempts to divide the welded cage due to advance and delay of the cylindrical roller acts in the circumferential direction. Since the welded portions 108 and 109 are weaker in strength than the first annular portion 106 and the second annular portion 107, the welded portions 108 and 109 are easily divided.

Among the plurality of pocket holes 20, the welded portions 30 at both ends of the belt-shaped steel plate 11 are positioned in the first annular portion 21 that forms one pocket hole 20. Among the plurality of pocket holes 20, the welded portions 33 at both ends of the belt-shaped steel plate 11 are positioned in the second annular portion 22 that forms one pocket hole 20. With respect to the pocket hole 20 having the welded portion 30, the welded portion 33 is provided in the fourth pocket hole 20 in the circumferential direction. Welding beats 31 are formed on both sides in the axial direction of the strip-shaped steel plate 11 of the welded portion 30, and the welding beats 31 are removed by a grinder or the like. Further, welding beats 34 are formed on both sides in the axial direction of the strip-shaped steel plate 11 of the butt welding portion 33, and the welding beats 34 are removed by a grinder or the like.

溶接部３０があるポケット孔２０と、溶接部３３があるポケット孔２０との間にある４つの柱部２６は、これの軸方向の中間で帯状鋼板１１の両端部を有する。柱部２６は、第１環状部２１側の柱片２７と、第２環状部２２側の柱片２８とからなり、柱片２７および柱片２８を軸方向に突合せ溶接することによって、柱片２７の端部と柱片２８の端部間に溶接部３６が形成されるようになっている。溶接部３６の円周方向両側に溶接ビート３７が形成され、この溶接ビート３７はグラインダー等によって除去されるようになっている。   The four columnar portions 26 between the pocket hole 20 with the welded portion 30 and the pocket hole 20 with the welded portion 33 have both ends of the strip-shaped steel plate 11 in the middle in the axial direction thereof. The column portion 26 includes a column piece 27 on the first annular portion 21 side and a column piece 28 on the second annular portion 22 side, and the column piece 27 and the column piece 28 are butt welded in the axial direction, thereby A welded portion 36 is formed between the end portion 27 and the end portion of the column piece 28. Welding beats 37 are formed on both sides of the welded portion 36 in the circumferential direction, and the welding beats 37 are removed by a grinder or the like.

ポケット孔２０は、円周方向両側の柱部２５、２６と、軸方向両側の第１環状部２１および第２環状部２２とで囲まれた平面視矩形形状（図２）をなしている。柱部２５、２６は円周方向に一定幅で軸方向に延びる部分であり、第１環状部２１および第２環状部２２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 the column portions 25 and 26 on both sides in the circumferential direction and the first annular portion 21 and the second annular portion 22 on both sides in the axial direction. The column portions 25 and 26 are portions extending in the axial direction with a constant width in the circumferential direction, and the first annular portion 21 and the second annular portion 22 are portions extending in the circumferential direction with a constant width in the axial direction.

次に図１および図２にもとづいて、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ＳＰＣＣからなるフープ材を用いることができる。   Next, a method for manufacturing the welded cage 10 will be described with reference to FIGS. 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-shaped steel plate 11, for example, a hoop material made of SPCC having excellent formability can be used.

溶接保持器１０の展開平面を作るのに、打ち抜きプレス金型が使用され、打ち抜きプレス金型によって、複数のポケット２０、柱部２５、２６、第１環状部２１、第２環状部２２が形成されると同時に、フープ材から帯状鋼板１１が切断される。フープ材から切断するときに、４つの柱部２６をこれの軸方向の中間で切断して、柱部２６を柱片２７と柱片２８とに分け、４つの柱部２６を挟んで円周方向両側にある一方のポケット孔２０を形成する第１環状部２１を一方のポケット孔２０の円周方向の中間で切断し、他方のポケット孔２０を形成する第２環状部２２を他方のポケット孔２０の円周方向の中間で切断する。こうして切断された帯状鋼板１１は、６個のポケット孔２０を形成する第１環状部２１および第２環状部２２を中間に有し、一方に４．５個のポケット孔２０を形成する第１環状部２１と、４個の柱片２７と、０．５個のポケット孔２０を形成する第２環状部２２が突出し、他方に０．５個のポケット孔２０を形成する第１環状部２１と、４個の柱片２８と、４．５個のポケット孔２０を形成する第２環状部２２が突出している。   A punching press die is used to form a development plane of the welded cage 10, and a plurality of pockets 20, column portions 25 and 26, a first annular portion 21, and a second annular portion 22 are formed by the punching press die. At the same time, the strip steel plate 11 is cut from the hoop material. When cutting from the hoop material, the four column portions 26 are cut in the middle in the axial direction to divide the column portion 26 into the column pieces 27 and 28 and sandwich the four column portions 26 with the circumference. The first annular portion 21 forming one pocket hole 20 on both sides in the direction is cut in the middle of one pocket hole 20 in the circumferential direction, and the second annular portion 22 forming the other pocket hole 20 is cut into the other pocket. Cut in the middle of the hole 20 in the circumferential direction. The strip-shaped steel plate 11 thus cut has a first annular portion 21 and a second annular portion 22 that form six pocket holes 20 in the middle, and a first that forms 4.5 pocket holes 20 on one side. The annular portion 21, the four column pieces 27, and the second annular portion 22 that forms 0.5 pocket holes 20 protrude, and the first annular portion 21 that forms 0.5 pocket holes 20 on the other side. Further, the four annular pieces 28 and the second annular portion 22 forming the 4.5 pocket holes 20 protrude.

帯状鋼板１１を折り曲げプレス金型にセットし、折り曲げプレス金型によって、帯状鋼板１１は環状に折り曲げ成形される。この結果、４個の柱片２７および４個の柱片２８は、帯状鋼板１１の円周方向において同位置にあり、第１環状部２１の両端部は互いに接触し、第２環状部２２の両端部は互いに接触する。第１環状部２１および第２環状部の両端部に図略の電極をそれぞれ接触させ、電流を流す。電流が両端部間を流れるときの抵抗熱によって両端部間が溶け、かかる状態で円周方向に突合せ荷重をかけることによって両端部が一体化する。続いて、柱片２７、２８に図略の電極をそれぞれ接触させ、電流を流す。電流が柱片２７、２８間を流れるときの抵抗熱によって柱片２７、２８間が溶け、かかる状態で帯状鋼板１１の軸方向に突合せ荷重をかけることによって柱片２７、２８同士が一体化する。   The belt-shaped steel plate 11 is set in a bending press mold, and the belt-shaped steel plate 11 is bent into an annular shape by the bending press mold. As a result, the four column pieces 27 and the four column pieces 28 are in the same position in the circumferential direction of the strip-shaped steel plate 11, both end portions of the first annular portion 21 are in contact with each other, and the second annular portion 22 Both ends are in contact with each other. Electrodes (not shown) are brought into contact with both ends of the first annular portion 21 and the second annular portion, respectively, and a current flows. Both ends are melted by resistance heat when current flows between both ends, and both ends are integrated by applying a butt load in the circumferential direction in this state. Subsequently, electrodes (not shown) are brought into contact with the column pieces 27 and 28, respectively, and a current is passed. The column pieces 27 and 28 are melted by the resistance heat generated when the current flows between the column pieces 27 and 28, and the column pieces 27 and 28 are integrated by applying a butt load in the axial direction of the strip steel plate 11 in this state. .

第１環状部２１の両端部間には溶接部３０が形成され、溶接部３０の帯状鋼板１１の軸方向に溶接ビート３１がはみ出す。第２環状部２１の両端部間には溶接部３３が形成され、溶接部３３の帯状鋼板１１の軸方向に溶接ビート３４がはみ出す。柱片２７、２８間には溶接部３６が形成され、溶接部３６の帯状鋼板１１の円周方向に溶接ビート３７がはみ出す。また各溶接部３０、３３、３６から帯状鋼板１１の径方向に溶接肉がはみ出す。溶接ビート３１、３３、３７およびはみ出た溶接肉は、グラインダー等で除去される。こうして、ころ軸受用溶接保持器１０が完成する。溶接方法は、上記の電気抵抗溶接以外にアーク溶接、ガス溶接等の公知の溶接方法でも実施することができる。   A welded portion 30 is formed between both end portions of the first annular portion 21, and the welding beat 31 protrudes in the axial direction of the strip-shaped steel plate 11 of the welded portion 30. A welded portion 33 is formed between both end portions of the second annular portion 21, and the weld beat 34 protrudes in the axial direction of the strip-shaped steel plate 11 of the welded portion 33. A welded portion 36 is formed between the column pieces 27 and 28, and the weld beat 37 protrudes in the circumferential direction of the strip-shaped steel plate 11 of the welded portion 36. Further, the weld meat protrudes from the welded portions 30, 33, 36 in the radial direction of the strip-shaped steel plate 11. The welding beats 31, 33, 37 and the protruding weld meat are removed with a grinder or the like. In this way, the roller bearing welded cage 10 is completed. The welding method can be carried out by a known welding method such as arc welding or gas welding in addition to the above electric resistance welding.

こうして作られたころ軸受用溶接保持器１０は、図略の円筒ころとともに図略の外輪および図略の内輪間に挿入される。例えば、外輪に対し内輪を回転させると、円筒ころは外輪および内輪上を転動し、ころ軸受用溶接保持器１０は内輪と同方向に回転する。外輪および内輪間には、例えば円周１箇所に大きなラジアル荷重が作用し、ラジアル荷重が作用しているところに向けて円筒ころの進み遅れが増大し、ラジアル荷重が作用しているところを通過すると円筒ころは進み遅れを取り戻す。このため、ころ軸受用溶接保持器１０には円周方向に引っ張り荷重が作用し、この引っ張り荷重はラジアル荷重が作用しているところに向けて増大する。引っ張り最大荷重は、第１環状部２１および溶接部３３、あるいは溶接部３０および第２環状部２２、あるいは第１環状部および第２環状部２２に作用するため、ころ軸受用溶接保持器１０が円周上の１箇所で分断することはない。つまり、溶接部３０および溶接部３３に引っ張り最大荷重が同時に作用しない。   The roller bearing welded cage 10 made in this way is inserted between an unillustrated outer ring and an unillustrated inner ring together with an unillustrated cylindrical roller. For example, when the inner ring is rotated with respect to the outer ring, the cylindrical roller rolls on the outer ring and the inner ring, and the roller bearing welded cage 10 rotates in the same direction as the inner ring. Between the outer ring and the inner ring, for example, a large radial load is applied to one place on the circumference, and the advance and delay of the cylindrical roller increases toward the place where the radial load is applied, and passes through the place where the radial load is applied. The cylindrical roller then regains the delay. For this reason, a tensile load acts on the roller bearing welded cage 10 in the circumferential direction, and this tensile load increases toward the place where the radial load is acting. The maximum tensile load acts on the first annular portion 21 and the welded portion 33, the welded portion 30 and the second annular portion 22, or the first annular portion and the second annular portion 22. There is no division at one point on the circumference. That is, the maximum tensile load does not act on the welded portion 30 and the welded portion 33 at the same time.

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.

上述した実施形態は、溶接部３０があるポケット孔２０に対し、円周方向に４つ目のポケット孔２０に溶接部３３を設けた。他の実施形態として、溶接部３０あるポケット孔２０に対し、円周方向に１つ目のポケット孔２０に溶接部３３を設けても良い。この場合、柱片２７および柱片２８間の溶接部３７が１個となるので、溶接コストを減らすことができる。さらに他の実施形態として、溶接部３０あるポケット孔２０に対し、円周方向に６つ目のポケット孔２０に溶接部３３を設けても良い。この場合、溶接部３０および溶接部３３にかかるトータルの引っ張り荷重が小さくなるので、より分断しにくくなる。どの実施形態も、同じポケット孔２０に溶接部３０および溶接部３３を設けない。   In the embodiment described above, the welded portion 33 is provided in the fourth pocket hole 20 in the circumferential direction with respect to the pocket hole 20 having the welded portion 30. As another embodiment, the welded portion 33 may be provided in the first pocket hole 20 in the circumferential direction with respect to the pocket hole 20 in the welded portion 30. In this case, since there is only one welded portion 37 between the column piece 27 and the column piece 28, the welding cost can be reduced. As another embodiment, the welded portion 33 may be provided in the sixth pocket hole 20 in the circumferential direction with respect to the pocket hole 20 in the welded portion 30. In this case, since the total tensile load applied to the welded part 30 and the welded part 33 is reduced, it becomes more difficult to divide. In any embodiment, the weld 30 and the weld 33 are not provided in the same pocket hole 20.

上述した溶接保持器１０は、円筒ころ軸受用溶接保持器に限らず、針状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 cylindrical roller bearing welded cage but can be applied to a needle roller bearing welded cage.
