Description

この発明は、複数の柱部と、内外径円環部の少なくとも一つを別部材とした、分割式の転がり軸受用保持器に関する。   The present invention relates to a split type rolling bearing cage in which at least one of a plurality of column parts and an inner and outer diameter annular part is a separate member.

転がり軸受は、図９に示すように、内輪１５に保持器１６を被せるとともにこの保持器１６のポケット７にころ８を設け、さらに外輪１７を取り付け、内輪１５と外輪１７が軸心周りにスムーズに相対回転するようにしている。この内外輪１５、１７の少なくとも一方には、つば１８（１８ａ、１８ｂ）が形成され、このつば１８に、ころ８の端面が当接することによって、軸受からころ８が脱落するのを防止している。
この保持器１６を図１０に示して説明すると、この保持器１６は、小径側円環部２と、大径側円環部３と、両円環部２、３をつなぐ柱部１とから構成され、この柱部１同士の間の隙間がころ８を収納するポケット７となっている。 In the rolling bearing, as shown in FIG. 9, the inner ring 15 is covered with a cage 16, and a roller 8 is provided in the pocket 7 of the cage 16, and an outer ring 17 is attached. The inner ring 15 and the outer ring 17 are smoothly around the axis. The relative rotation is made. At least one of the inner and outer rings 15, 17 is formed with a collar 18 (18 a, 18 b), and the end surface of the roller 8 abuts on the collar 18 to prevent the roller 8 from falling off the bearing. Yes.
The retainer 16 will be described with reference to FIG. 10. The retainer 16 includes a small-diameter-side annular portion 2, a large-diameter-side annular portion 3, and a column portion 1 that connects both annular portions 2 and 3. The gap between the pillar portions 1 is a pocket 7 for storing the rollers 8.

例えば、円錐ころ軸受においては、同図に示すように、内輪１５の大径側に大つば１８ａ、小径側に小つば１８ｂがそれぞれ形成されるのが一般的である。そして、軸受のアセンブリに際しては、保持器１６のころ内接円径が小つば外径よりも大きくなるように小径側円環部２を拡径させ（いわゆる「底拡げ」を行い）、その拡径させた状態で、保持器１６ところ８を内輪１５に嵌め込み、この嵌め込み後に、小径側円環部２の内径を専用工具を用いて正規の寸法に戻している（いわゆる「加締め」を行う）。   For example, in a tapered roller bearing, as shown in the figure, generally, a large collar 18a is formed on the large diameter side of the inner ring 15, and a small collar 18b is formed on the small diameter side. When assembling the bearing, the small-diameter side annular portion 2 is expanded (so-called “bottom expansion”) so that the roller inscribed circle diameter of the cage 16 is larger than the small collar outer diameter. In a state where the diameter is made, the cage 16 is fitted into the inner ring 15, and after this fitting, the inner diameter of the small-diameter side annular portion 2 is returned to a normal dimension using a dedicated tool (so-called “caulking” is performed). ).

しかしながら、この加締めが不十分な場合、ころ８と保持器１６のポケット７の当たり不良が生じて、ポケット７の内面が異常摩耗して円滑な相対回転に問題が生じたり、保持器１６に局所的に力が加わって、この保持器１６の破損やこれに伴う軸受のトラブルが生じたりする可能性がある。   However, if this caulking is insufficient, a contact failure between the roller 8 and the pocket 7 of the cage 16 occurs, and the inner surface of the pocket 7 wears abnormally, causing a problem in smooth relative rotation. If force is applied locally, the cage 16 may be damaged or a bearing trouble may occur.

このような問題を回避すべく、下記特許文献１には、保持器の底拡げ及び加締めを行うことなく、内輪に転動体を設けた保持器を嵌め込むようにした構成が開示されている。この構成では、内輪の小つばの部分を内輪本体とは別部材として自在に取り外しできるようにし、保持器を嵌め込む際には、前記小つばを内輪本体から一旦外しておく。そして、この保持器の嵌め込み後に、小つばを内輪本体に固定して、保持器及び転動体の脱落を防止している。   In order to avoid such a problem, the following Patent Document 1 discloses a configuration in which a cage provided with a rolling element is fitted into an inner ring without expanding and caulking the cage. . In this configuration, the small brim portion of the inner ring can be freely removed as a separate member from the inner ring main body, and when the retainer is fitted, the small brim is temporarily removed from the inner ring main body. After the cage is fitted, the small brim is fixed to the inner ring main body to prevent the cage and rolling elements from falling off.

実開平３−６５０１７号公報Japanese Utility Model Publication No. 3-65017

前記内輪に形成するつばは、上述したように、転動体の端面に当接してその脱落を防止するためのものである。このため、前記特許文献１に示すように、小つばを分離可能な構成とすると、転動体がこの小つばに当接した際に、この当接の衝撃によって、小つばが内輪本体から外れる恐れがある。この場合、外れた小つばと、この小つば側から脱落した転動体によって、軸受に大きなトラブルが生じる可能性が高い。
そこで、この発明は、この軸受のアセンブリの際に、保持器の底拡げ及び加締めを行うことなく、この保持器を内輪に嵌め込むとともに、内輪に形成したつばによって、転動体を安定して保持することを課題とする。 As described above, the collar formed on the inner ring is for coming into contact with the end face of the rolling element to prevent its falling off. For this reason, as shown in the above-mentioned Patent Document 1, when the small brim is configured to be separable, when the rolling element comes into contact with the small brim, the small brim may be detached from the inner ring main body due to the impact of the contact. There is. In this case, there is a high possibility that a big trouble will occur in the bearing due to the detached small brim and the rolling elements that have fallen off the small brim side.
Therefore, in the present invention, when the bearing is assembled, the cage is fitted into the inner ring without performing the bottom expansion and caulking of the cage, and the rolling element is stably formed by the collar formed on the inner ring. It is an issue to hold.

上記課題を解決するため、この発明は、複数の柱部と、小径側円環部と、大径側円環部とを有する転がり軸受用保持器において、前記柱部と小径側円環部、又は、前記柱部と大径側円環部とを分離不可能な一体部材とする一方で、前記一体部材に嵌め込む大径側円環部又は小径側円環部をこの一体部材とは別部材とし、前記一体部材とした柱部、及び、前記別部材とした大径側円環部又は小径側円環部の双方に嵌合部を形成し、前記一体部材と、別部材である大径側円環部又は小径側円環部とを、前記嵌合部によって連結する構成とした。   In order to solve the above problems, the present invention provides a rolling bearing retainer having a plurality of pillars, a small-diameter-side annular part, and a large-diameter-side annular part, the pillar part and the small-diameter-side annular part, Alternatively, the column portion and the large-diameter-side annular portion are made an integral member that cannot be separated, while the large-diameter-side annular portion or the small-diameter-side annular portion that is fitted into the integral member is separated from the integral member. A fitting portion is formed in both the pillar portion as the member, the pillar portion as the integral member, and the large-diameter side annular portion or the small-diameter side annular portion as the separate member, and the integral member is a large separate member. The diameter-side annular portion or the small-diameter-side annular portion is connected by the fitting portion.

この構成とすることにより、保持器の小径側又は大径側のいずれか一方の円環部が開放された状態となっていることから、内輪の大小の両つばが付いたままの状態でも、この保持器の底拡げを行うことなく、その開放端側（円環部が別部材となっている側）から容易にこの保持器（一体部材）を内輪に被せることができる。このため、加締め作業も不要となって、加締め不良に起因する軸受トラブルを防止することができる。   By adopting this configuration, either the small-diameter side or the large-diameter side of the cage is in an open state, so that the inner ring has both large and small collars attached, The cage (integral member) can be easily put on the inner ring from the open end side (side where the annular portion is a separate member) without expanding the bottom of the cage. For this reason, the caulking work is also unnecessary, and the bearing trouble caused by the caulking failure can be prevented.

前記柱部と、小径側円環部又は大径側円環部のいずれを一体化するかについては、内輪の軌道面の両側に形成したつばの大きさを考慮した上で、一体部材を嵌め込みやすいように適宜決定する。   Whether to integrate the pillar portion with the small-diameter side annular portion or the large-diameter side annular portion is based on the size of the collar formed on both sides of the raceway surface of the inner ring, and is fitted with an integral member. Decide as appropriate to make it easier.

上記構成の代わりに、複数の柱部と、小径側円環部と、大径側円環部とを有する転がり軸受用保持器において、前記柱部が固定柱部と別体柱部とからなり、前記固定柱部と、小径側円環部及び大径側円環部とを分離不可能な一体部材とする一方で、前記別体柱部をこの一体部材とは別部材とし、前記一体部材とした小径側円環部及び大径側円環部、及び、別部材とした別体柱部の双方に嵌合部を形成し、前記一体部材と、別部材である別体柱部とを、前記嵌合部によって連結する構成とすることもできる。   Instead of the above configuration, in a rolling bearing retainer having a plurality of pillars, a small-diameter-side annular part, and a large-diameter-side annular part, the pillar part is composed of a fixed pillar part and a separate pillar part. The fixed column part and the small-diameter-side annular part and the large-diameter-side annular part are an integral member that cannot be separated, while the separate pillar part is a separate member from the integral member, and the integral member The small-diameter side annular part and the large-diameter side annular part, and the separate pillar part as a separate member are formed with fitting parts, and the integral member and the separate pillar part as a separate member It can also be set as the structure connected by the said fitting part.

この別体柱部を採用する構成においては、前記固定柱部と別体柱部とが、軸受の周方向に交互に配置されるようにするのがより好ましい。   In the configuration employing the separate column portion, it is more preferable that the fixed column portion and the separate column portion are alternately arranged in the circumferential direction of the bearing.

このように固定柱部と別体柱部を交互に配置すると、回転対称性が良好となり、内外輪の円滑な相対回転を確保できるとともに、回転の際の異音や振動等の発生を防止することができる。   When the fixed column portion and the separate column portion are alternately arranged in this manner, the rotational symmetry becomes good, and the smooth relative rotation of the inner and outer rings can be secured, and the occurrence of abnormal noise or vibration during rotation is prevented. be able to.

この固定柱部と別体柱部を交互に配置する代わりに、例えば、固定柱部の間に三個のころを嵌め込み、各ころの間に別体柱部を設ける構成としてもよい。   Instead of alternately arranging the fixed column portions and the separate column portions, for example, three rollers may be fitted between the fixed column portions, and separate column portions may be provided between the rollers.

また、別体柱部を採用する前記構成においては、各別体柱部を別々に円環部に取り付ける代わりに、別体柱部の一方の端部をリング部材に所定間隔をおいて固定しておき、この別体柱部を固定した柱部付リング部材を一体部材に取り付けるようにすることもできる。   Further, in the above configuration employing the separate column part, instead of attaching each separate column part to the annular part separately, one end of the separate column part is fixed to the ring member at a predetermined interval. It is also possible to attach the ring member with a column portion to which the separate column portion is fixed to the integrated member.

前記所定間隔とは、前記別体柱部を円環部に固定した際の、別体柱部同士の間隔のことを指し、このように所定間隔を置くことで、一つの別体柱部を円環部に固定すると、他の別体柱部も円環部の所定位置（その別体柱部を固定すべき位置）に配置される。このため、前記他の別体柱部を固定する際に、一つ一つ位置調整をする必要がなく、作業の煩雑さが軽減される。   The predetermined interval refers to the interval between the separate column portions when the separate column portion is fixed to the annular portion, and by placing a predetermined interval in this way, one separate column portion is obtained. When fixed to the annular part, the other separate column part is also arranged at a predetermined position of the annular part (position where the separate column part is to be fixed). For this reason, when fixing the said another separate pillar part, it is not necessary to adjust a position one by one, and the complexity of an operation | work is reduced.

上記各構成においては、一方の前記嵌合部が穴状の雌形嵌合部、他方の前記嵌合部が突起状の雄形嵌合部であって、前記雌形嵌合部及び雄形嵌合部の双方に、それらの幅方向に突出する凸部を形成し、前記雌形嵌合部に雄形嵌合部を嵌め込んだ状態で引き抜き力が作用した際に、前記両嵌合部の凸部同士が係合して、この嵌合部同士の抜け止めがなされるようにすることもできる。   In each of the above configurations, one of the fitting portions is a hole-shaped female fitting portion, and the other fitting portion is a protruding male fitting portion, and the female fitting portion and the male shape Both of the fitting portions are formed with protrusions projecting in the width direction, and when the pulling force is applied with the male fitting portion fitted into the female fitting portion. The convex portions of the portions can be engaged with each other to prevent the fitting portions from coming off.

このように嵌合部の抜け止めがなされるようにしておくことで、軸受の使用中に保持器が分離して転動体が脱落するトラブルを未然に防止することができる。   By preventing the fitting part from coming off in this way, it is possible to prevent a trouble that the cage is separated and the rolling elements fall off during use of the bearing.

あるいは、一方の前記嵌合部が穴状の雌形嵌合部、他方の前記嵌合部が突起状の雄形嵌合部であって、前記雌形嵌合部又は雄形嵌合部の少なくとも一方に、ディンプル状の突起を形成し、この突起と対向する嵌合部との間の摩擦力によって、嵌合部同士の抜け止めがなされるようにすることもできる。   Alternatively, one of the fitting portions is a hole-shaped female fitting portion, and the other fitting portion is a protruding male fitting portion, and the female fitting portion or the male fitting portion It is also possible to form dimple-shaped protrusions on at least one and prevent the fitting parts from coming off by the frictional force between the protrusions and the fitting parts facing each other.

このディンプル状の突起も嵌合部の抜け止めに有効に作用して、前記凸部と同様に転動体が脱落するトラブルを未然に防止することができる。   This dimple-like projection also effectively acts to prevent the fitting portion from coming off, and the trouble that the rolling elements fall off can be prevented in advance as in the case of the convex portion.

前記柱部と小径側円環部、又は、前記柱部と大径側円環部を一体部材とする構成においては、別部材である前記大径側円環部又は小径側円環部と、前記一体部材とが、軸受の外径方向に段差を形成することなく、前記嵌合部において連結されるように構成することもできる。   In the configuration in which the pillar part and the small diameter side annular part, or the pillar part and the large diameter side annular part as an integral member, the large diameter side annular part or the small diameter side annular part which is a separate member, The integral member may be configured to be coupled at the fitting portion without forming a step in the outer diameter direction of the bearing.

このように結合部において段差を形成しないようにすることにより、軸受使用時の保持器のブレが生じても、小径側円環部と外輪軌道面が接触すること無く、転動体の安定した回転状態を確保することができる。   By not forming a step in the coupling portion in this way, even if the cage is shaken during use of the bearing, stable rotation of the rolling element without contact between the small-diameter-side annular portion and the outer ring raceway surface. A state can be secured.

前記別体柱部を採用する各構成においては、保持器のポケット内に、軸受の軸心方向にこのポケットの幅を拡大する凹部を形成し、この凹部に前記別体柱部の係合溝を嵌め込むようにすることもできる。   In each configuration employing the separate column portion, a recess that enlarges the width of the pocket in the axial direction of the bearing is formed in the pocket of the cage, and the engagement groove of the separate column portion is formed in the recess. Can also be fitted.

この凹部に嵌合部を嵌め込むと、軸受の使用時に、別体柱部が保持器の周方向にずれて動くのが防止される。このため、固定柱部とこの別体柱部の所定の間隔が維持されて、各柱部の間に嵌め込んだ転動体がポケット内の特定箇所に強く当接したり、がたついたりすることなく、軸受の相対回転を円滑に行うことができる。   When the fitting portion is fitted into the concave portion, the separate column portion is prevented from being displaced in the circumferential direction of the cage during use of the bearing. For this reason, the predetermined interval between the fixed column portion and the separate column portion is maintained, and the rolling elements fitted between the respective column portions strongly contact or rattle a specific location in the pocket. The relative rotation of the bearing can be performed smoothly.

前記加工構成に係る保持器においては、前記一体部材が鉄製であって、別部材である小径側円環部又は大径側円環部が樹脂性とするのが好ましい。
一体部材を鉄製とすることによって、転動体を嵌め込んだときの強度を担保する一方で、円環部を樹脂製とすることで前記一体部材へのこの円環部の嵌め込みを容易に行い得るからである。 In the cage according to the processing configuration, it is preferable that the integral member is made of iron, and the small-diameter side annular part or the large-diameter side annular part as a separate member is made of resin.
By making the integral member made of iron, the strength when the rolling element is fitted can be secured, while the annular portion can be made of resin so that the annular portion can be easily fitted into the integral member. Because.

また、前記構成においては、前記樹脂を、ポリフェニレンサルファイド（ＰＰＳ）又はポリアミド９Ｔ（ＰＡ９Ｔ）とするのが特に好ましい。   Moreover, in the said structure, it is especially preferable to make the said resin into polyphenylene sulfide (PPS) or polyamide 9T (PA9T).

これらの樹脂は、熱膨張率が鉄とほぼ同じなので、軸受の使用に伴ってその内部温度が上昇しても、前記一体部材と円環部の熱膨張率の差に起因して、これらが分解してしまう恐れは低い。また、これらの樹脂は吸水膨張しにくいので、常に高い寸法精度を確保することができる。このため、軸受の安定した相対回転が確保できる。   These resins have almost the same coefficient of thermal expansion as iron, so even if the internal temperature rises with the use of the bearing, these are due to the difference in coefficient of thermal expansion between the integral member and the annular part. The risk of disassembly is low. Moreover, since these resins are difficult to absorb and expand, high dimensional accuracy can always be ensured. For this reason, the stable relative rotation of a bearing is securable.

また、前記各構成における転がり軸受は、円錐ころ軸受とするのが好ましい。
この円錐ころ軸受は内輪の軌道面が大径側から小径側に傾斜しているため、転動体の脱落防止のためにこの小径側には、つばが形成されている。このため、保持器を上述したように一体部材と別体部材とで構成して、この一体部材を前記つばを乗り越えて容易に内輪に嵌め込み得るようにした本願発明の構成は、前記円錐ころ軸受への適用に特に適している。 Moreover, it is preferable that the rolling bearing in each said structure is a tapered roller bearing.
In this tapered roller bearing, since the raceway surface of the inner ring is inclined from the large diameter side to the small diameter side, a flange is formed on the small diameter side to prevent the rolling elements from falling off. For this reason, the structure of the present invention in which the cage is composed of the integral member and the separate member as described above, and the integral member can be easily fitted into the inner ring over the collar is the tapered roller bearing. Particularly suitable for application to.

この発明によると、転がり軸受の保持器の柱部又は内外径円環部を別部材としたので、軸受のアセンブリの際に、保持器の底拡げ及び加締めを行う必要がない。このため、このアセンブリに伴う煩雑さを大幅に軽減することができる。また、この保持器の内輪のつばを内輪本体から分離不可能な構成としたので、転動体がこのつばに当接してもこのつばが内輪本体から外れることがない。このため、このつばによって転動体を安定して保持することができる。   According to the present invention, since the column portion or the inner and outer diameter ring portions of the cage of the rolling bearing are separate members, it is not necessary to perform the bottom expansion and caulking of the cage during the assembly of the bearing. For this reason, the complexity associated with this assembly can be greatly reduced. Further, since the collar of the inner ring of the cage cannot be separated from the inner ring main body, even if the rolling element comes into contact with the collar, the collar does not come off from the inner ring main body. For this reason, a rolling element can be stably hold | maintained with this collar.

この発明に係る転がり軸受用保持器の一実施形態を図１に示す。この保持器は、円錐ころ軸受用のものであって、複数の柱部１と、小径側円環部２と、大径側円環部３とで構成されている。この柱部１と大径側円環部３は分離不可能な一体部材４となっている一方で、この一体部材４に嵌め込む小径側円環部２は、この一体部材４とは別部材となっている。   One embodiment of a rolling bearing cage according to the present invention is shown in FIG. This cage is for a tapered roller bearing and includes a plurality of column portions 1, a small-diameter-side annular portion 2, and a large-diameter-side annular portion 3. The column portion 1 and the large-diameter side annular portion 3 are an inseparable integral member 4, while the small-diameter side annular portion 2 fitted into the integral member 4 is a separate member from the integral member 4. It has become.

図１乃至３に示すように、この一体部材４を構成する柱部１の端部には突起状の雄形嵌合部５が形成される一方で、小径側円環部２には、穴状の雌形嵌合部６がそれぞれ形成され、両嵌合部５、６の嵌め合いによって、一体部材４と小径側円環部２とを連結している。また、両嵌合部５、６にはそれらの幅方向に突出する凸部５ａ、６ａがそれぞれ形成され、雌形嵌合部６に雄形嵌合部５を嵌め込んだ状態で引き抜き力が作用した際に、両嵌合部５、６の凸部５ａ、６ａ同士が係合して、この嵌合部５、６同士の抜け止めがなされるようになっている。このように凸部５ａ、６ａを形成する代わりに、ディンプル状の突起を多数形成して、この突起と対向する嵌合部５、６との間の摩擦力によって、抜け止めを図るようにしてもよい。   As shown in FIGS. 1 to 3, a protruding male fitting portion 5 is formed at the end portion of the column portion 1 constituting the integrated member 4, while the small-diameter side annular portion 2 has a hole. A female fitting portion 6 is formed, and the integral member 4 and the small-diameter side annular portion 2 are connected by fitting the fitting portions 5 and 6 together. Further, the fitting portions 5 and 6 are respectively formed with convex portions 5a and 6a protruding in the width direction thereof, and the pulling force is applied in a state where the male fitting portion 5 is fitted into the female fitting portion 6. When acting, the projections 5a and 6a of the fitting parts 5 and 6 are engaged with each other, and the fitting parts 5 and 6 are prevented from coming off. Instead of forming the protrusions 5a and 6a in this way, a large number of dimple-shaped protrusions are formed, and the frictional force between the fitting parts 5 and 6 facing the protrusions is used to prevent the protrusions from being removed. Also good.

この一体部材４は、所定厚さの鉄板をプレス加工成形したものであって、この保持器のポケット７に収納した円錐ころ８を安定的に保持し得る強度を有している。その一方で、小径側円環部２は射出成形法によって樹脂を成形したものであって、一体部材４の素材である鉄と同程度の熱膨張率を有するとともに、吸水性が低く寸法安定性に優れるポリフェニレンサルファイド（ＰＰＳ）が使用されている。この小径側円環部２の素材は、ＰＰＳと同等の熱膨張率等の材料物性を有するポリアミド９Ｔ（ＰＡ９Ｔ）に置き換えることもできる。   The integral member 4 is obtained by press-molding an iron plate having a predetermined thickness, and has a strength capable of stably holding the tapered rollers 8 housed in the pockets 7 of the cage. On the other hand, the small-diameter side annular portion 2 is formed by resin molding by an injection molding method, has a thermal expansion coefficient comparable to that of iron that is a material of the integral member 4, and has low water absorption and dimensional stability. Polyphenylene sulfide (PPS), which is excellent in the quality, is used. The material of the small-diameter side annular portion 2 can be replaced with polyamide 9T (PA9T) having material properties such as a thermal expansion coefficient equivalent to PPS.

なお、図１等に示した構成では、小径側円環部２が一体部材４の柱部よりも、その連結部において軸受の外径方向に突出した構成となっているが、図４（ａ）及び（ｂ）に示すように、小径側円環部２が柱部１から突出しないようにすることもできる。このようにすれば、軸受使用時に保持器のブレが生じても、小径側円環部２と外輪１７の軌道面が接触すること無く、円錐ころ８の安定した回転を確保することができる。   In the configuration shown in FIG. 1 and the like, the small-diameter-side annular portion 2 is configured to protrude in the outer diameter direction of the bearing at the connecting portion rather than the column portion of the integral member 4, but FIG. ) And (b), it is possible to prevent the small-diameter side annular portion 2 from protruding from the column portion 1. In this way, even if the cage is shaken when the bearing is used, stable rotation of the tapered roller 8 can be ensured without contact between the raceway surface of the small-diameter side annular portion 2 and the outer ring 17.

この発明に係る転がり軸受用保持器の他の実施形態を図５（ａ）及び（ｂ）に示す。この保持器も円錐ころ軸受用のものであって、複数の柱部１と、小径側円環部２と、大径側円環部３とで構成されている。この柱部１と小径側円環部２は分離不可能な一体部材４となっている一方で、この一体部材４に嵌め込む大径側円環部３は、この一体部材４とは別部材となっている。   Another embodiment of a rolling bearing cage according to the present invention is shown in FIGS. This cage is also for tapered roller bearings, and is composed of a plurality of column parts 1, a small-diameter side annular part 2, and a large-diameter side annular part 3. The column portion 1 and the small-diameter-side annular portion 2 are an integral member 4 that cannot be separated, while the large-diameter-side annular portion 3 that is fitted into the integral member 4 is a separate member from the integral member 4. It has become.

そして、この一体部材４を構成する柱部１の端部に穴状の雌形嵌合部６を形成するとともに、大径側円環部３に突起状の雄形嵌合部５を形成し、両嵌合部５、６に凸部５ａ、６ａを形成することによって、図１等の構成と同様に、嵌合部５、６同士の抜け止め作用が発揮される。   And while forming the hole-shaped female fitting part 6 in the edge part of the pillar part 1 which comprises this integrated member 4, the protrusion-shaped male fitting part 5 is formed in the large diameter side annular part 3. By forming the convex portions 5a and 6a on the fitting portions 5 and 6, the retaining action between the fitting portions 5 and 6 is exhibited as in the configuration of FIG.

この発明に係る転がり軸受用保持器のさらに他の実施形態を図６（ａ）〜（ｃ）に示す。この保持器も、円錐ころ軸受用のものであって、複数の柱部１と、小径側円環部２と、大径側円環部３とで構成されている。この柱部１は、固定柱部９と別体柱部１０とからなり、この固定柱部９と、小径側円環部２及び大径側円環部３は分離不可能な一体部材４となっている一方で、この一体部材４に嵌め込む別体柱部１０は、この一体部材４とは別部材となっている。   Still another embodiment of the cage for a rolling bearing according to the present invention is shown in FIGS. This cage is also for tapered roller bearings, and is composed of a plurality of column portions 1, a small-diameter-side annular portion 2, and a large-diameter-side annular portion 3. The column portion 1 includes a fixed column portion 9 and a separate column portion 10, and the fixed column portion 9, the small-diameter side annular portion 2, and the large-diameter side annular portion 3 are inseparable from an integral member 4. On the other hand, the separate column part 10 fitted into the integrated member 4 is a separate member from the integrated member 4.

この別体柱部１０の両端には係合溝１１が形成されている。隣り合う固定柱部９、９の間に形成されるポケット７に二個の円錐ころ８、８を収納した後に、同図（ｂ）に示すように、別体柱部１０の係合溝１１を小径側円環部２及び大径側円環部３の所定位置に嵌め込む。そうすると、ポケット７に収納した二個の円錐ころ８、８が、ポケット７内で互いに接触することなく、円滑に回転することができる。この別体柱部１０の両端部にはテーパ１２が形成されており、このテーパ１２によって、小径側円環部２及び大径側円環部３がスムーズに係合溝１１に案内されるようにしている。   Engaging grooves 11 are formed at both ends of the separate column portion 10. After storing the two tapered rollers 8 and 8 in the pocket 7 formed between the adjacent fixed column portions 9 and 9, as shown in FIG. Are inserted into predetermined positions of the small-diameter side annular portion 2 and the large-diameter side annular portion 3. If it does so, the two tapered rollers 8 and 8 accommodated in the pocket 7 can rotate smoothly, without contacting each other in the pocket 7. FIG. Tapers 12 are formed at both ends of the separate column part 10 so that the small-diameter side annular part 2 and the large-diameter side annular part 3 are smoothly guided to the engaging groove 11 by the taper 12. I have to.

この固定柱部９と別体柱部１０は、周方向に交互に配置されている。このため回転対称性が良好であって、円錐ころ８の回転をスムーズに行うことができる。   The fixed column portions 9 and the separate column portions 10 are alternately arranged in the circumferential direction. For this reason, the rotational symmetry is good and the tapered roller 8 can be smoothly rotated.

この構成においては、図７（ａ）及び（ｂ）に示すように、ポケット７内に、軸受の軸心方向にこのポケット７の幅を拡大する凹部１３を形成し、この凹部１３に別体柱部１０の係合溝１１を嵌め込むようにしてもよい。このようにすると、別体柱部１０の周方向位置が凹部１３の位置に固定されて、この軸受の使用中に別体柱部１０が不用意に周方向に動かない。このため、円錐ころ８同士の所定の間隔が維持されて、この円錐ころ８の安定した回転状態を確保することができる。   In this configuration, as shown in FIGS. 7A and 7B, a recess 13 is formed in the pocket 7 so as to increase the width of the pocket 7 in the axial direction of the bearing, and the recess 13 is separately provided. The engaging groove 11 of the column part 10 may be fitted. If it does in this way, the peripheral direction position of separate pillar part 10 will be fixed to the position of crevice 13, and separate pillar part 10 will not move in the peripheral direction carelessly during use of this bearing. For this reason, the predetermined space | interval of the tapered rollers 8 is maintained, and the stable rotation state of this tapered roller 8 can be ensured.

この別体柱部１０は、図６及び７に示したように、一つずつ一体部材４に設ける構成としてもよいが、図８に示すように、各別体柱部１０の一方の端部をリング部材１４に所定間隔をおいて固定した構成とすることもできる。この別体柱部１０は断面が略「コ」の字形をしており（同図（ａ）を参照）、外力を加えて「コ」の字の開口側に別体柱部１０を変形させつつ、一体部材４のポケット７に嵌め込む。この嵌め込み後は、別体柱部１０が元の形状に戻って、ポケット内で突っ張った状態となるため、この別体柱部１０が抜け落ちることはない。   6 and 7, the separate column portions 10 may be provided on the integrated member 4 one by one, but as shown in FIG. 8, one end portion of each separate column portion 10. The ring member 14 may be fixed at a predetermined interval. This separate column part 10 has a substantially “U” -shaped cross section (see FIG. 1A), and an external force is applied to deform the separate column part 10 toward the opening side of the “U” character. While fitting into the pocket 7 of the integral member 4. After the fitting, the separate column portion 10 returns to its original shape and is stretched in the pocket, so that the separate column portion 10 does not fall off.

また、この一体部材４同士はリング部材１４で連結されているため、一つの別体柱部１０を嵌め込むことによって、他の別体柱部１０も、所定位置（別体柱部１０を固定すべき位置）に配置される。このため、この別体柱部１０を嵌め込む際に、一つ一つ位置調整をする必要がなく、作業の煩雑さが軽減される。   In addition, since the integrated members 4 are connected to each other by a ring member 14, by inserting one separate column portion 10, another separate column portion 10 is also fixed at a predetermined position (the separate column portion 10 is fixed. To be placed). For this reason, when this separate column part 10 is fitted, it is not necessary to adjust the position one by one, and the complexity of the work is reduced.

さらに、同図（ｃ）に示すように、この別体柱部１０と両円環部２、３との係合部分に凸部１０ａを形成しておくと、一体部材４に別体柱部１０を嵌め込んだ際の抜け止め作用が発揮され、円錐ころ８の保持が一層確実なものとなる。   Further, as shown in FIG. 5C, when a convex portion 10a is formed at the engaging portion between the separate column portion 10 and the two annular portions 2, 3, the separate column portion is formed on the integral member 4. The retaining action when 10 is fitted is exhibited, and the tapered roller 8 is more reliably held.

なお、一体部材４と円環部２、３又は別体柱部１０を一体化する場合は、その連結箇所に接着剤を使用してもよい。連結の確実性が高まって、軸受の使用の際に不具合が生じる恐れを一層低減し得るからである。この接着剤の選択に際しては、樹脂素材としてＰＰＳを使用する場合はエポキシ系やシリコーン系の接着剤を使用する必要がある。このＰＰＳは耐薬品性に優れる反面、上記以外の接着剤では十分な接着力が得られないためである。前記エポキシ系接着剤の中でも、特にＥＰ−００１（セメダイン（株）製）が強固な接着力を得られる点で有効である。   In addition, when integrating the integral member 4 and the ring parts 2, 3 or the separate pillar part 10, you may use an adhesive agent for the connection location. This is because the reliability of the connection is increased, and the risk of occurrence of problems when the bearing is used can be further reduced. When selecting the adhesive, it is necessary to use an epoxy or silicone adhesive when PPS is used as the resin material. This PPS is excellent in chemical resistance, but a sufficient adhesive force cannot be obtained with an adhesive other than the above. Among the epoxy adhesives, EP-001 (manufactured by Cemedine Co., Ltd.) is particularly effective in obtaining a strong adhesive force.
