A bearing can be provided.

以下、本発明の実施の形態を図面に基づいて説明する。
図１は、本発明の第１の実施形態に係るころ軸受の部分断面図である。同図において、符号１１は外輪、１２は内輪であって、外輪１１の内周面には環状の転動体軌道面１３が形成されている。この転動体軌道面１３は内輪１２の外周面に形成された転動体軌道面１４と対向しており、外輪１１と内輪１２との間には、転動体である複数のころ１５を保持する保持器１６が設けられている。
保持器１６は、図２及び図３に示すように、転動体１５の中心部に形成されたピン挿通孔１９を挿通して転動体１５を回転自在に支持する複数本の支持ピン１７（図では１本のみを図示）と、これら支持ピン１７を介して転動体１５を保持する一対の環状側板１８，１８とから構成されている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a partial cross-sectional view of a roller bearing according to a first embodiment of the present invention. In the figure, reference numeral 11 denotes an outer ring, 12 denotes an inner ring, and an annular rolling element raceway surface 13 is formed on the inner peripheral surface of the outer ring 11. The rolling element raceway surface 13 faces a rolling element raceway surface 14 formed on the outer peripheral surface of the inner ring 12, and a plurality of rollers 15 that are rolling elements are held between the outer ring 11 and the inner ring 12. A vessel 16 is provided.
As shown in FIGS. 2 and 3, the retainer 16 is inserted into a pin insertion hole 19 formed at the center of the rolling element 15, and a plurality of support pins 17 (see FIG. 2) for rotatably supporting the rolling element 15. , Only one is shown), and a pair of annular side plates 18 and 18 that hold the rolling elements 15 via the support pins 17.

支持ピン１７は、例えばＪＩＳ Ｇ４０５１ Ｓ２５Ｃ以上（炭素含有量がＳ２５Ｃ相当以上）の機械構造用炭素鋼から形成されている。また、支持ピン１７はＨｖ３００以上（好ましくはＨｖ３５０以上）の硬さを有する高周波焼入れ層２０（図３参照）を有しており、この高周波焼入れ層２０は転動体１５と接触する部分に形成されている。
環状側板１８は、例えばＪＩＳ Ｓ１０Ｃ〜Ｓ３５Ｃ程度の機械構造用炭素鋼あるいはこれらの規格に相当する鉄鋼材料で形成されている。また、環状側板１８はＨｖ１００〜Ｈｖ２７０（好ましくはＨｖ１００〜Ｈｖ２００）程度の硬さを有しており、各環状側板１８には、複数のピン圧入孔２１（図３参照）が環状側板１８の円周方向に等間隔で穿設されている。 The support pin 17 is made of, for example, JIS G4051 S25C or higher (carbon content equal to or higher than S25C) carbon steel for machine structures. Further, the support pin 17 has an induction hardening layer 20 (see FIG. 3) having a hardness of Hv 300 or more (preferably Hv 350 or more), and the induction hardening layer 20 is formed in a portion in contact with the rolling element 15. ing.
The annular side plate 18 is formed of, for example, carbon steel for machine structure of about JIS S10C to S35C or a steel material corresponding to these standards. The annular side plate 18 has a hardness of about Hv100 to Hv270 (preferably Hv100 to Hv200), and each annular side plate 18 has a plurality of pin press-fitting holes 21 (see FIG. 3). It is drilled at equal intervals in the circumferential direction.

支持ピン１７の両端部は環状側板１８に形成されたピン圧入孔２１に圧入されており、環状側板１８の外側面には、ピン圧入孔２１に圧入された支持ピン１７の両端部を環状側板１８に結合するための溶接部２２（図３参照）がティグ溶接、プラズマアーク溶接等の溶加材（フィラー）を用いない溶接方法で形成されている。
上述のように、支持ピン１７の両端部を環状側板１８に形成されたピン圧入孔２１に圧入し、ピン圧入孔２１に圧入された支持ピン１７の両端部を環状側板１８に結合するための溶接部２２を環状側板１８の外側面に形成したことで、前述した従来技術のように、テーパブッシュを使用したり、支持ピンにテーパ加工やねじ加工を施したりする必要がないので、部品点数の増加やコストの上昇を抑えることができる。 Both ends of the support pin 17 are press-fitted into pin press-fitting holes 21 formed in the annular side plate 18, and both ends of the support pins 17 press-fitted into the pin press-fitting holes 21 are inserted into the outer side surface of the annular side plate 18. A welded portion 22 (see FIG. 3) for joining to 18 is formed by a welding method that does not use a filler material (filler) such as TIG welding or plasma arc welding.
As described above, both ends of the support pin 17 are press-fitted into the pin press-fit holes 21 formed in the annular side plate 18, and both ends of the support pins 17 press-fitted into the pin press-fit holes 21 are coupled to the annular side plate 18. Since the welded portion 22 is formed on the outer surface of the annular side plate 18, there is no need to use a taper bush or to taper or thread the support pin as in the prior art described above. Increase and cost increase can be suppressed.

また、溶接部２２をティグ溶接あるいはプラズマアーク溶接のいずれかの溶接方法で形成した場合には、支持ピン１７と環状側板１８との結合部を円環状に溶接できる。なお、円環状以外に、円周上の複数箇所に溶接することも可能であり、円環状を含め等配に溶接してあることが望ましい。
なお、上述した実施形態では支持ピン１７をＪＩＳ Ｇ４０５１ Ｓ２５Ｃ以上の機械構造用炭素鋼で形成したが、例えばＪＩＳ Ｇ４４０１の炭素工具鋼あるいはこれらの規格に相当する炭素鋼から支持ピン１７を形成してもよく、焼入れ性がより多く必要な場合には、支持ピン１７の素材として、ＪＩＳ Ｇ４８０５の高炭素クロム軸受鋼、ＪＩＳ Ｇ４１０２のニッケルクロム鋼、ＪＩＳ Ｇ４１０３のニッケルクロムモリブデン鋼、ＪＩＳ Ｇ４１０４のクロム鋼、ＪＩＳ Ｇ４１０３のクロムモリブデン鋼などを用いてもよい。 Further, when the welded portion 22 is formed by a welding method of either TIG welding or plasma arc welding, the joint portion between the support pin 17 and the annular side plate 18 can be welded in an annular shape. In addition to the annular shape, it is also possible to weld to a plurality of locations on the circumference, and it is desirable that welding is performed evenly including the annular shape.
In the above-described embodiment, the support pin 17 is formed of carbon steel for machine structure of JIS G4051 S25C or more. For example, the support pin 17 is formed from carbon tool steel of JIS G4401 or carbon steel corresponding to these standards. If more hardenability is required, JIS G4805 high carbon chrome bearing steel, JIS G4102 nickel chrome steel, JIS G4103 nickel chrome molybdenum steel, JIS G4104 chrome steel are used as the material for the support pins 17. JIS G4103 chromium molybdenum steel or the like may be used.

また、上述した実施形態では支持ピン１７の軸径を全長にわたって同一径としたが、図４に示す第２の実施形態のように、環状側板１８のピン圧入孔２１に圧入される支持ピン１７の両端部のうち一方の端部（図中下側の端部）の軸径ｄ1を他方の端部（図中上側の端部）の軸径ｄ3より小さくしてもよい。
この場合、支持ピン１７の両端部のうち軸径が小さいほうの端部（図中下側の端部）の先端部に先細り状のテーパ部２３を形成することが好ましい。また、ピン圧入孔２１は支持ピン１７が圧入される側の周縁部に面取り部２４を有することが好ましい。 In the above-described embodiment, the shaft diameter of the support pin 17 is the same throughout the entire length. However, the support pin 17 press-fitted into the pin press-fitting hole 21 of the annular side plate 18 as in the second embodiment shown in FIG. The shaft diameter d 1 of one end (the lower end in the figure) may be smaller than the shaft diameter d 3 of the other end (the upper end in the figure).
In this case, it is preferable to form the tapered portion 23 at the tip end of the end portion (lower end portion in the figure) having the smaller shaft diameter among the both end portions of the support pin 17. Moreover, it is preferable that the pin press-fitting hole 21 has a chamfered portion 24 at the peripheral portion on the side where the support pin 17 is press-fitted.

上述のように、環状側板１８のピン圧入孔２１に圧入される支持ピン１７の両端部のうち一方の端部の軸径ｄ1を他方の端部の軸径ｄ3より小さくしたことで、一対の環状側板１８のうち一方の環状側板１８の外側面側から支持ピン１７を圧入できるので、保持器の組立を容易に行うことができる。
また、支持ピン１７の両端部のうち軸径が小さいほうの端部の先端部に先細り状のテーパ部２３を形成したことで、保持器を組立てる際に支持ピン１７を環状側板１８のピン圧入孔２１に容易に圧入することができる。さらに、ピン圧入孔２１の支持ピン１７が圧入される側の周縁部に面取り部２４を設けたことで、保持器を組立てる際に支持ピン１７を環状側板１８のピン圧入孔２１に容易に圧入することができる。 As described above, the shaft diameter d 1 of one end of the both ends of the support pin 17 that is press-fitted into the pin press-fitting hole 21 of the annular side plate 18 is made smaller than the shaft diameter d 3 of the other end. Since the support pin 17 can be press-fitted from the outer surface side of one annular side plate 18 of the pair of annular side plates 18, the assembly of the cage can be performed easily.
Further, since the tapered portion 23 is formed at the tip of the end portion having the smaller shaft diameter among the both end portions of the support pin 17, the support pin 17 is inserted into the pin of the annular side plate 18 when the cage is assembled. It can be easily press-fitted into the hole 21. Further, by providing a chamfer 24 at the peripheral edge of the pin press-fitting hole 21 on the side where the support pin 17 is press-fitted, the support pin 17 can be easily press-fitted into the pin press-fitting hole 21 of the annular side plate 18 when the cage is assembled. can do.

図５は本発明の第３の実施形態に係る軸受用保持器の部分断面図であり、この第３の実施形態が第２の実施形態と異なる点は、支持ピン１７が環状側板１８のピン圧入孔２１に圧入される両端部より軸径の小さい軸部１７ａを中央部に有する点、および軸部１７ａの軸方向長さＬを一方の環状側板１８の内側面と他方の環状側板１８の内側面との間隔Ｓより長くし、環状側板１８の中に支持ピン１７の両端部と軸部１７ａとの間の段差が存在する点である。このような構成であると、支持ピン１７の両端部と軸部１７ａとの間に生じた段差３０によって支持ピン１７がフレッチングにより損傷することを防止することができる。   FIG. 5 is a partial cross-sectional view of a bearing cage according to the third embodiment of the present invention. The third embodiment is different from the second embodiment in that the support pin 17 is a pin of the annular side plate 18. A point having a shaft portion 17a having a shaft diameter smaller than both end portions to be press-fitted into the press-fitting holes 21 in the center portion, and an axial length L of the shaft portion 17a are set to the inner side surface of one annular side plate 18 and the other annular side plate 18. It is longer than the distance S from the inner side surface, and there is a step between the both end portions of the support pin 17 and the shaft portion 17 a in the annular side plate 18. With such a configuration, it is possible to prevent the support pin 17 from being damaged by fretting due to the step 30 generated between both end portions of the support pin 17 and the shaft portion 17a.
