Description

本発明は、ピンタイプ保持器を備えたピンタイプ保持器付きころ軸受に関する。   The present invention relates to a roller bearing with a pin type cage provided with a pin type cage.

ピンタイプ保持器は、円周方向等間隔で複数のピン挿通孔を備えかつ互いに平行に配置された一対の環状板と、これら一対の環状板間に円周方向に等間隔に配置されそれぞれ貫通孔を有する複数の中空ころと、各中空ころそれぞれの貫通孔に挿通されて中空ころを回転可能に支持し、両端部が一対の環状板それぞれのピン挿通孔に固定された複数のピンとで構成されている。このようなピンタイプ保持器を備えたころ軸受においては、総ころ形ころ軸受に近い負荷容量が確保可能であると同時に、総ころ形ころ軸受の欠点である、ころのスキューが発生しない長所を備える（特許文献１，２，３，等参照）。   The pin type cage has a plurality of pin insertion holes at equal intervals in the circumferential direction and a pair of annular plates arranged in parallel to each other, and is arranged between the pair of annular plates at equal intervals in the circumferential direction and penetrates each. Consists of a plurality of hollow rollers having holes, and a plurality of pins that are inserted through the through holes of each hollow roller to rotatably support the hollow rollers, and both ends are fixed to the pin insertion holes of each of the pair of annular plates Has been. A roller bearing equipped with such a pin type cage can secure a load capacity close to that of a full-roller roller bearing, and at the same time has the advantage of not causing roller skew, which is a disadvantage of a full-roller roller bearing. Provided (see Patent Documents 1, 2, 3, etc.).

ところで、従来のピンタイプ保持器付きころ軸受では、環状板は、ピンを保持する機能を目的としているため、その外径が中空ころセットの外接円径（当該中空ころに外接する外輪の内径）以下であり、保持器全体が外輪から抜け出し易いという課題がある。
実開昭５０−１５０６５６号公報 特開平１１−３２５０６３号公報 特開２００２−９８１５３号公報 By the way, in the conventional roller bearing with a pin type cage, the annular plate is intended for the function of holding the pin, so the outer diameter is the circumscribed circle diameter of the hollow roller set (the inner diameter of the outer ring circumscribing the hollow roller) There is a problem that the entire cage is easily pulled out from the outer ring.
Japanese Utility Model Publication No. 50-150656 JP 11-325063 A JP 2002-98153 A

したがって、本発明により解決すべき課題は、保持器が外輪より容易に抜け出ない構造にすることである。   Therefore, the problem to be solved by the present invention is to provide a structure in which the cage is not easily pulled out from the outer ring.

本発明によるピンタイプ保持器付きころ軸受は、円周方向所定間隔で複数のピン固定孔を備えかつ互いに平行に配置された一対の環状板と、これら一対の環状板間に配置されかつ上記ピン固定孔それぞれに対応するピン挿通孔を有する複数の中空ころと、各中空ころのピン挿通孔に挿通されるとともに上記環状板の各ピン固定孔に固定される複数のピンとを備えるピンタイプ保持器付きころ軸受であって、上記一対の環状板それぞれの外径を、共に、上記複数の中空ころよりなるころセットの外接円径より大きくしたことを特徴とするものである。   A roller bearing with a pin type cage according to the present invention includes a pair of annular plates provided with a plurality of pin fixing holes at predetermined intervals in the circumferential direction and arranged in parallel to each other, and between the pair of annular plates and the pin A pin type retainer comprising: a plurality of hollow rollers having pin insertion holes corresponding to the respective fixing holes; and a plurality of pins inserted into the pin insertion holes of the respective hollow rollers and fixed to the pin fixing holes of the annular plate. In the roller bearing, the outer diameter of each of the pair of annular plates is larger than the circumscribed circle diameter of the roller set including the plurality of hollow rollers.

本発明によると、両環状板の外径が、共に、上記中空ころセットの外接円径より大きいから、当該保持器を外輪の内周面に装着した場合、例えば保持器に軸方向一方に抜け出しの力が作用しても、軸方向他方の環状板が外輪の軸方向他方の端面に係合し、軸方向他方方に抜け出しの力が作用しても、軸方向一方の環状板が外輪の軸方向一方の端面に係合するから、保持器が外輪より抜け出すことが無い。   According to the present invention, since the outer diameters of both the annular plates are both larger than the circumscribed circle diameter of the hollow roller set, when the cage is mounted on the inner peripheral surface of the outer ring, for example, the cage is pulled out in one axial direction. Even if this force is applied, the other annular plate in the axial direction is engaged with the other end surface in the axial direction of the outer ring, and even if a pulling force is applied in the other axial direction, the one annular plate in the axial direction is Since it engages with one end face in the axial direction, the cage does not come out of the outer ring.

本発明の好ましい実施態様として、上記複数のピンのうち、一部を上記ピン固定孔の外側孔部にかしめや溶接等の固定手段により固定し、残りを上記ピン固定孔に圧入により固定する。   As a preferred embodiment of the present invention, a part of the plurality of pins is fixed to the outer hole portion of the pin fixing hole by fixing means such as caulking or welding, and the rest is fixed to the pin fixing hole by press fitting.

上記態様の場合、トータル的にはかしめ等によりピン固定孔に対するピンの固定強度を確保でき、また、トータル的には、全体がコストのかかるかしめではなく、一部がコストが安く済む圧入だけでピンをピン固定孔に固定しているから、コストが安く済む。   In the case of the above aspect, the pin fixing strength with respect to the pin fixing hole can be secured by caulking or the like in total, and overall, the caulking is not costly as a whole, but only the press-fitting that partially reduces the cost. Since the pin is fixed to the pin fixing hole, the cost can be reduced.

本発明によると、保持器が外輪より抜け出すことを防止できる。   According to the present invention, it is possible to prevent the cage from coming out of the outer ring.

以下、添付図面を参照して、本発明のピンタイプ保持器付きころ軸受（以下、単にころ軸受という）に適用して説明する。図１は、ころ軸受の側面断面図、図２は、図１のＡ−Ａ線に沿う断面図、図３は、ころ軸受の分解斜視図である。これらの図において、このころ軸受は、外輪１０と、複数の中空ころ１１と、ピンタイプ保持器１２とを備える。   Hereinafter, with reference to the accompanying drawings, description will be made by applying the present invention to a roller bearing with a pin type cage (hereinafter simply referred to as a roller bearing). 1 is a side sectional view of a roller bearing, FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIG. 3 is an exploded perspective view of the roller bearing. In these drawings, the roller bearing includes an outer ring 10, a plurality of hollow rollers 11, and a pin type cage 12.

中空ころ１１は、軸心を貫通する、軸方向全長にわたり同一内径でかつ断面円形をなすピン挿通孔１３を備える。ピンタイプ保持器１２は、中空ころ１１のピン挿通孔１３に挿通されて該中空ころ１１を回転自在に保持するピン１４と、円環状でかつ互いに同軸上を平行に配置されかつピン１４の両端が圧入されるピン固定孔１５を有する一対の環状板１６とを有する。この環状板１６のピン固定孔１５は、その内径が、中空ころ１１のピン挿通孔１３の内径より小さくされている。ピン１４は、中空ころ１１を回転自在とする外径を備えた断面円形を有してピン挿通孔１３に挿入されるピン本体１７と、ピン本体１７の外径よりも小さいが、環状板１６のピン固定孔１５に圧入可能な外径を有するピン両端１８とからなる。この構成により、ピン１４は、ピン本体１７とそのピン両端１８との外径差により軸方向に段付き構成なっている。ピン本体１７は、中空ころ１１のピン挿通孔１３に挿入されるとともに当該ピン挿通孔１３外に突き出されて、環状板１６の内端面に当接しているとともに、ピン両端１８は、該ピン固定孔１５に圧入されるとともにその外側孔部１７にかしめられて固定されている。このかしめに代えて溶接やその他の固定手段で固定することでもよい。なお、上記の場合、ピン両端１８を上記固定手段で固定することは、コストがかかるので、環状板１６のピン固定孔１５に圧入だけで固定してコスト低減を図ってもよい。   The hollow roller 11 includes a pin insertion hole 13 that penetrates the shaft center and has the same inner diameter and a circular cross section over the entire length in the axial direction. The pin type retainer 12 is inserted into the pin insertion hole 13 of the hollow roller 11 to rotatably hold the hollow roller 11, and is annular and arranged coaxially in parallel with each other and both ends of the pin 14. And a pair of annular plates 16 each having a pin fixing hole 15 into which is inserted. The pin fixing hole 15 of the annular plate 16 has an inner diameter smaller than the inner diameter of the pin insertion hole 13 of the hollow roller 11. The pin 14 has a circular cross section with an outer diameter that allows the hollow roller 11 to rotate, and is inserted into the pin insertion hole 13. The pin 14 is smaller than the outer diameter of the pin body 17, but the annular plate 16 And both pin ends 18 having an outer diameter capable of being press-fitted into the pin fixing hole 15. With this configuration, the pin 14 has a stepped configuration in the axial direction due to a difference in outer diameter between the pin body 17 and both ends 18 of the pin. The pin body 17 is inserted into the pin insertion hole 13 of the hollow roller 11 and protrudes out of the pin insertion hole 13 so as to be in contact with the inner end face of the annular plate 16. While being press-fitted into the hole 15, it is caulked and fixed to the outer hole 17. Instead of this caulking, it may be fixed by welding or other fixing means. In the above case, since it is costly to fix the pin ends 18 with the fixing means, it may be fixed to the pin fixing hole 15 of the annular plate 16 only by press fitting to reduce the cost.

ピン１４のピン本体１７は、中空ころ１１の内周面との摺動摩擦抵抗を低減して潤滑を向上する等のため、皮膜処理、表面硬化処理等を施してもよい。皮膜処理としては、リン酸マンガン酸亜鉛の皮膜形成、二硫化モリブデン等の層状物質系のコーティング、ベーキングによる焼成皮膜の形成、スズ、亜鉛、銀、クロム（硬質クロム）、その他の金属のメッキ等がある。ＰＴＦＥ、ポリイミド等の高分子系の固体潤滑皮膜の形成がある。表面硬化処理としては、浸硫窒化、浸硫、液体窒化、レーザビーム焼入れ、高周波焼入れ、浸炭焼入れ、ショットピーニング等がある。あるいは、耐摩耗、耐かじり、耐焼付き性の向上のため、タフトライド処理、イオン窒化処理等の熱処理を施してもよい。上記処理は、中空ころ１１のピン挿通孔１３の内周面や、中空ころ１１の外周面、外輪１０の内周面、 環状板１６の外輪１０の外端面と接触する箇所等に施してもよい。   The pin main body 17 of the pin 14 may be subjected to a film treatment, a surface hardening treatment, or the like in order to reduce sliding frictional resistance with the inner peripheral surface of the hollow roller 11 and improve lubrication. Film treatment includes zinc manganate film formation, layered material coating such as molybdenum disulfide, baking film formation by baking, tin, zinc, silver, chromium (hard chrome), plating of other metals, etc. There is. There is the formation of a polymer-based solid lubricating film such as PTFE or polyimide. Examples of the surface hardening treatment include nitrosulphurizing, sulfiding, liquid nitriding, laser beam hardening, induction hardening, carburizing and quenching, and shot peening. Alternatively, heat treatment such as tuftride treatment or ion nitriding treatment may be performed in order to improve wear resistance, galling resistance, and seizure resistance. The above treatment may be applied to the inner peripheral surface of the pin insertion hole 13 of the hollow roller 11, the outer peripheral surface of the hollow roller 11, the inner peripheral surface of the outer ring 10, a portion that contacts the outer end surface of the outer ring 10 of the annular plate 16, etc. Good.

そして、環状板１６の外径Ｒ１は、複数の中空ころ１１からなる中空ころセットの外接円径（中空ころ１１が外接する外輪１０の内径）Ｒ２より大きくされており、かつ、ピン１４のピン両端１８は、環状板１６のピン固定孔１５の外側孔部１７にかしめられている。   The outer diameter R1 of the annular plate 16 is larger than the circumscribed circle diameter (inner diameter of the outer ring 10 to which the hollow roller 11 circumscribes) R2 of the hollow roller set composed of the plurality of hollow rollers 11, and the pin 14 Both ends 18 are caulked to the outer hole 17 of the pin fixing hole 15 of the annular plate 16.

以上の構成を備えたころ軸受においては、両環状板１６の外径が、共に、中空ころ１１のセットの外接円径より大きいから、当該保持器１２を外輪１０の内周面に装着した場合、当該保持器１２に軸方向一方に抜け出しの力が作用しても、軸方向他方の環状板１６が外輪１０の軸方向他方の端面に係合し、軸方向他方方に抜け出しの力が作用しても、軸方向一方の環状板１６が外輪の軸方向一方の端面に係合するから、保持器１２が外輪１０より抜け出すことが無い。また、ピン１４がピン本体１７とピン両端１８とで軸方向段付き形状になり、かつ、ピン本体１７がピン挿通孔１３外で環状板１６の内端面に当接しているから、ピン１４そのものが環状板１６から抜け出すのを確実に防止できる。   In the roller bearing having the above configuration, since the outer diameters of both annular plates 16 are both larger than the circumscribed circle diameter of the set of hollow rollers 11, the cage 12 is mounted on the inner peripheral surface of the outer ring 10. Even if a pulling force acts on the cage 12 in one axial direction, the other annular plate 16 in the axial direction engages with the other axial end surface of the outer ring 10, and a pulling force acts on the other axial direction. Even so, the one annular plate 16 in the axial direction engages with one end face in the axial direction of the outer ring, so that the cage 12 does not come out of the outer ring 10. Further, since the pin 14 has an axially stepped shape between the pin body 17 and the both ends 18 of the pin, and the pin body 17 is in contact with the inner end surface of the annular plate 16 outside the pin insertion hole 13, the pin 14 itself Can be reliably prevented from coming out of the annular plate 16.

（他の形態）
図４ないし図６を参照して本発明の他の形態（第２形態）を説明する。図４は、本発明の他の形態に係るころ軸受の側面断面図、図５は、図４のＢ−Ｂ線に沿う断面図、図６は、図４のＣ−Ｃ線に沿う断面図である。図１ないし図３と対応する部分には、同一の符号を付している。第２形態が、図１ないし図３に示す形態（第１形態）と相違するのは、第１形態では、すべてのピン１４のピン両端１８が、環状板１６のピン固定孔１５の外側孔部１７にかしめ等の固定手段で固定されているのに対して、第２形態では、上記複数のピン１４のうち、一部のピン両端１８を環状板１６のピン固定孔１５の外側孔部１７にかしめまたは溶接等により固定し、残りのピン両端１８をピン固定孔１５に圧入だけで固定していることである。すなわち、ピン両端１８のすべてを固定手段で固定した場合、固定強度は得られても、製造コストが高くつく一方、ピン両端１８のすべてを圧入だけで固定すると製造コストは安くても、固定強度に劣る。これに対して、第２形態の場合、すべてのピン１４がピン固定孔１５にコストがかかるかしめや溶接等で固定されておらず、一部だけがピン固定孔１５にかしめや溶接等の固定手段で固定されている一方、残りが、かしめや溶接等が施されず、圧入だけで固定されているから、トータル的には必要な固定強度を得られると同時にその製造コストの低減を図ることが可能となる。上記ピン１４のうち、ピン両端１８を、固定手段で固定するピン数と、圧入だけで固定するピン数との割合は、固定強度とコストとの関係により適宜に決定することができる。 (Other forms)
Another embodiment (second embodiment) of the present invention will be described with reference to FIGS. 4 is a side sectional view of a roller bearing according to another embodiment of the present invention, FIG. 5 is a sectional view taken along line BB in FIG. 4, and FIG. 6 is a sectional view taken along line CC in FIG. It is. Parts corresponding to those in FIGS. 1 to 3 are denoted by the same reference numerals. The second form is different from the form shown in FIGS. 1 to 3 (first form). In the first form, the pin ends 18 of all the pins 14 are outside holes of the pin fixing holes 15 of the annular plate 16. Whereas the second embodiment is fixed to the portion 17 by fixing means such as caulking, in the second embodiment, a part of both ends 18 of the plurality of pins 14 is connected to the outer hole portion of the pin fixing hole 15 of the annular plate 16. 17 is fixed by caulking or welding or the like, and the other end 18 of the pin is fixed to the pin fixing hole 15 only by press fitting. That is, when all of the pin ends 18 are fixed by the fixing means, even if the fixing strength is obtained, the manufacturing cost is high. On the other hand, if all of the pin ends 18 are fixed only by press-fitting, the fixing strength is low. Inferior to On the other hand, in the case of the second embodiment, all the pins 14 are not fixed to the pin fixing holes 15 by caulking, welding or the like, and only a part is fixed to the pin fixing holes 15 by caulking, welding or the like. While the rest is fixed by means, the rest is not crimped or welded, and is fixed only by press-fitting, so that the necessary fixing strength can be obtained in total and the manufacturing cost can be reduced at the same time Is possible. Of the pins 14, the ratio between the number of pins that fix the pin ends 18 by the fixing means and the number of pins that are fixed only by press-fitting can be appropriately determined according to the relationship between the fixing strength and the cost.

なお、外輪１０の両端部は、図７で示すように、軸方向に延ばし、その内周面を軸方向に段付きにしてもよい。   In addition, as shown in FIG. 7, both ends of the outer ring 10 may extend in the axial direction, and the inner peripheral surface thereof may be stepped in the axial direction.
