保持器の外径が非常に大きくなると、大型のプレス金型を作ることが困難となるので、板材をカップ状に折り曲げ成形することが困難となる。このため外径の大きい保持器(例えば、外径が1000mm)は、肉厚のある1枚の板材にポケットをミーリング加工によって形成しているのが現状である。ミーリング加工に時間がかかりコスト高となる。また前記ポケットは、保持器の軸方向に真っ直ぐ形成されるので、一対のレース間に保持器および複数のころを組付けるときに、ころがポケットから脱落しやすく、組付け作業が非常に大変である。本発明は上述した問題点を解決するためになされたもので、その目的は、安価に製作でき、一対のレース間への組付けが容易なスラスト用保持器を提供する。   When the outer diameter of the cage becomes very large, it becomes difficult to make a large press die, and it becomes difficult to bend the plate material into a cup shape. For this reason, a cage having a large outer diameter (for example, an outer diameter of 1000 mm) currently has a pocket formed on one thick plate material by milling. Milling takes time and costs are high. In addition, since the pocket is formed straight in the axial direction of the cage, when the cage and a plurality of rollers are assembled between a pair of races, the rollers easily fall out of the pocket, and the assembling work is very difficult. is there. The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a thrust cage that can be manufactured at low cost and can be easily assembled between a pair of races.

請求項1に記載の発明は、円盤状の板材からなり、複数のころを円周方向に間隔を空けて配置するとともに放射状に配置するポケットを形成したスラスト用保持器であって、前記板材は、これよりも板厚が薄い薄板材を3枚以上積層したものであり、中間積層の前記薄板材に前記ポケットを構成する第1の収納穴を形成し、中間積層の両外側に配置される前記薄板材に前記ポケットを構成する第2の収納穴を形成し、前記第1の収納穴は前記ころの外径よりも大きめに切断にて形成し、前記第2の収納穴は前記ころの外径よりも小さめに切断にて形成し、各薄板材を積み重ねる過程で前記第1の収納穴および前記第2の収納穴に前記ころを収納し、前記第1の収納穴および前記第2の収納穴が一致するように前記各薄板材を位置決めする位置決め手段を設け、位置決めされた複数の前記薄板材を互いに連結する連結手段を設けたことを特徴とするものである。   The invention according to claim 1 is a thrust retainer comprising a disk-shaped plate material, in which a plurality of rollers are arranged at intervals in the circumferential direction, and pockets for radially arranging are formed, wherein the plate material is , Three or more thin plate materials having a thinner plate thickness are laminated, and a first storage hole that constitutes the pocket is formed in the thin plate material of the intermediate laminate, and is disposed on both outer sides of the intermediate laminate. A second storage hole constituting the pocket is formed in the thin plate material, the first storage hole is formed by cutting larger than the outer diameter of the roller, and the second storage hole is formed in the roller. The roller is stored in the first storage hole and the second storage hole in the process of stacking the thin plate materials by cutting to be smaller than the outer diameter, and the first storage hole and the second storage hole. Position for positioning each thin plate material so that the storage holes match The fit means provided and is characterized in that a connecting means for connecting together a plurality of said thin plate being positioned.

本発明によれば、切断にてポケットを形成することができるので、安価に製作することができる。また、第1の収納穴および第2の収納穴によって、ころが抜けないように保持することができるので、一対のレース間への組付けが容易になる。   According to the present invention, since the pocket can be formed by cutting, it can be manufactured at low cost.

図2および図3に示すように、スラスト用ころ軸受10は、図略のハウジングに設けられる第1のレース11と、図略の回転軸に設けられる第2のレース20と、第1のレース11および第2のレース20間に配置され第1のレース11および第2のレース20上を転動する複数の円筒ころ40と、複数のころを円周方向に間隔を空けて配置するとともに放射状に配置する保持器30とからなっている。第1のレース11、第2のレース20、円筒ころ40、保持器30は、いずれも鉄系の材料からなっている。   As shown in FIGS. 2 and 3, the thrust roller bearing 10 includes a first race 11 provided in a not-illustrated housing, a second race 20 provided on a not-shown rotating shaft, and a first race. A plurality of cylindrical rollers 40 arranged between the first race 11 and the second race 20 and rolling on the first race 11 and the second race 20, and a plurality of rollers spaced apart in the circumferential direction and arranged radially. And a retainer 30 disposed in the housing. The first race 11, the second race 20, the cylindrical roller 40, and the cage 30 are all made of an iron-based material.

第1のレース11および第2のレース20は、円盤状の板材である。第1のレース11および第2のレース20の少なくとも円筒ころ40側の面に焼入れ、焼き戻し処理が施され、円筒ころ40の転動による摩耗に耐えられるようになっている。   The first race 11 and the second race 20 are disk-shaped plate materials. The first race 11 and the second race 20 are subjected to quenching and tempering treatment on at least the surface on the cylindrical roller 40 side so as to be able to withstand wear due to rolling of the cylindrical roller 40.

円筒ころ40は、円筒形状を有する。円筒ころ40は、第1のレース11および第2のレース20上を転動する転動面41と、後述するポケット35に接触する端面42を有する。端面42は、保持器30の外径側のポケット35に接触する端面と、保持器30の内径側のポケット35に接触する端面とがある。   The cylindrical roller 40 has a cylindrical shape. The cylindrical roller 40 has a rolling surface 41 that rolls on the first race 11 and the second race 20, and an end surface 42 that comes into contact with a pocket 35 described later. The end surface 42 has an end surface that contacts the pocket 35 on the outer diameter side of the cage 30 and an end surface that contacts the pocket 35 on the inner diameter side of the cage 30.

図1に示すように保持器30は、円盤状の板材である。図2乃至図4に示すように板材は、この板厚よりも薄い薄板材を複数枚積層したものである。保持器30は、複数のころ40を円周方向に間隔を空けて配置するとともに放射状に配置するポケット35を有する。保持器30は、第1の薄板材31、第2の薄板材32、第3の薄板材33、第4の薄板材34を順に積層したものである。   As shown in FIG. 1, the cage 30 is a disk-shaped plate material. As shown in FIGS. 2 to 4, the plate material is obtained by laminating a plurality of thin plate materials thinner than the plate thickness. The cage 30 has pockets 35 in which a plurality of rollers 40 are arranged at intervals in the circumferential direction and are arranged radially. The cage 30 is formed by sequentially laminating a first thin plate material 31, a second thin plate material 32, a third thin plate material 33, and a fourth thin plate material 34.

図2に示すように第1の薄板材31および第4の薄板材34にポケット35を構成する第2の収納穴31a、34aが形成され、第2の薄板材32および第3の薄板材33にポケット35を構成する第1の収納穴32a、33aが形成されている。第1の収納穴32a、33aは、円筒ころ40の外径よりも大きめに切断によって形成され、第2の収納穴31a、34aは、円筒ころ40の外径よりも小さめに切断によって形成されている。第1の収納穴32a、33aは、円筒ころ40の軸方向長さよりも大きめに切断によって形成され、第2の収納穴31a、34aは、円筒ころ40の軸方向長さよりも極僅かに大きめに切断によって形成されている。   As shown in FIG. 2, second storage holes 31 a and 34 a that form pockets 35 are formed in the first thin plate material 31 and the fourth thin plate material 34, and the second thin plate material 32 and the third thin plate material 33. The first storage holes 32a and 33a constituting the pocket 35 are formed in the first storage hole 32a. The first storage holes 32a and 33a are formed by cutting larger than the outer diameter of the cylindrical roller 40, and the second storage holes 31a and 34a are formed by cutting smaller than the outer diameter of the cylindrical roller 40. Yes. The first storage holes 32 a and 33 a are formed by cutting larger than the axial length of the cylindrical roller 40, and the second storage holes 31 a and 34 a are slightly larger than the axial length of the cylindrical roller 40. It is formed by cutting.

第1の収納穴32a、33aおよび第2の収納穴31a、34aは、レーザ加工の切断によって形成される。レーザ加工による切断面は、第1の薄板材31、第2の薄板材32、第3の薄板材33、第4の薄板材34の板厚が、薄くなればなるほどきれいになる傾向にある。逆に第1の薄板材31、第2の薄板材32、第3の薄板材33、第4の薄板材34の板厚が厚くなればなるほど、切断面が汚くなり、ミーリング加工できれいに整える必要が出てくる。   The first storage holes 32a and 33a and the second storage holes 31a and 34a are formed by laser processing cutting. The cut surface by the laser processing tends to be cleaner as the plate thicknesses of the first thin plate material 31, the second thin plate material 32, the third thin plate material 33, and the fourth thin plate material 34 become thinner. Conversely, the thicker the thickness of the first thin plate material 31, the second thin plate material 32, the third thin plate material 33, and the fourth thin plate material 34, the more the cut surface becomes dirty, and it is necessary to prepare it neatly by milling processing. Comes out.

第2の収納穴31a、34aは、円筒ころ40と接触するので、できるだけきれいな加工面が必要となる。第2の収納穴31a、34aは、レーザ加工で切断した後、ミーリング加工で加工面をきれいに整える。第1の収納穴32a、33aは、円筒ころ40と接触しないので、きれいな加工面を必要としない。第1の収納穴32a、33aは、レーザ加工で切断したままである。このように、レーザ加工による切断を使用することにより、ミーリング加工時間が減り、保持器30の製作費が安価となる。   Since the second storage holes 31a and 34a are in contact with the cylindrical roller 40, a processed surface that is as clean as possible is required. After the second storage holes 31a and 34a are cut by laser processing, the processed surfaces are neatly prepared by milling. Since the first storage holes 32a and 33a do not contact the cylindrical roller 40, a clean processed surface is not required. The first storage holes 32a and 33a remain cut by laser processing. Thus, by using cutting by laser processing, milling processing time is reduced, and the manufacturing cost of the cage 30 is reduced.

薄板材の枚数は、保持器30の全体の肉厚、レーザ加工による切断面の状況、ミーリング加工時間に応じて適宜決められる。すなわち、レーザ加工時間とミーリング加工時間を合わせたトータルの加工時間が短くなるように、薄板材の枚数が決められる。   The number of thin plate materials is appropriately determined according to the overall thickness of the cage 30, the state of the cut surface by laser processing, and the milling time. That is, the number of thin plate materials is determined so that the total processing time including the laser processing time and the milling processing time is shortened.

図1および図3に示すように第1の薄板材31、第2の薄板材32、第3の薄板材33、第4の薄板材34には、円周上2箇所にピン穴51が形成され、このピン穴51にピン50が差し込まれている。ピン穴51およびピン50によって、第1の収納穴32a、33aおよび第2の収納穴31a、34aが互いに一致し、第1の収納穴32a、33aおよび第2の収納穴31a、34aによってポケット35が構成される。   As shown in FIGS. 1 and 3, pin holes 51 are formed at two locations on the circumference of the first thin plate material 31, the second thin plate material 32, the third thin plate material 33, and the fourth thin plate material 34. The pin 50 is inserted into the pin hole 51. By the pin hole 51 and the pin 50, the first storage holes 32a, 33a and the second storage holes 31a, 34a coincide with each other, and the pockets 35 are formed by the first storage holes 32a, 33a and the second storage holes 31a, 34a.

A welding beat 56 is formed by welding the letter-shaped groove 55. On the inner circumference of the first thin plate material 31, the second thin plate material 32, the third thin plate material 33, and the fourth thin plate material 34, V-shaped grooves 57 are formed at equal intervals on the circumference. A weld beat 58 is formed by welding the V-shaped groove 57. The first thin plate member 31, the second thin plate member 32, the third thin plate member 33, and the fourth thin plate member 34 are connected to each other by the welding beats 56 and 58.
