Description
【０００１】[0001]
この考案は針状ころ軸受用保持器に関し、例えば遊星歯車機構における遊星歯 車を支持する針状ころ軸受に用いられる。 The present invention relates to a needle roller bearing cage, and is used, for example, in a needle roller bearing that supports a planetary gear in a planetary gear mechanism.
【０００２】[0002]
遊星歯車減速機における遊星歯車を支持する構成の一例を図４に示す。遊星歯 車１は、キャリア２、２に固定した軸３に総ころタイプの針状ころ軸受４を介し て支持され、また、その針状ころ軸受４と遊星歯車１の両側面にはそれぞれスラ ストワッシャ５、５が介在される。軸受４は、保持器付きのものもあるが、総こ ろタイプが一般的である。 FIG. 4 shows an example of a structure for supporting the planetary gears in the planetary gear reducer. The planetary gear 1 is supported on a shaft 3 fixed to carriers 2 and 2 through a full-roller type needle roller bearing 4, and the needle roller bearing 4 and the planetary gear 1 are slidable on both sides. Stowers 5, 5 are interposed. The bearing 4 may be provided with a retainer, but it is generally a full bearing type.
【０００３】[0003]
自動車に搭載される遊星歯車減速機の場合、自動車の高性能化により遊星歯車 も高速回転での使用が増加しており、また遊星歯車は強度上ねじれ角を有するよ うに設計されているため、前記のスラストワッシャ５のＰＶ値が高くなり、該ス ラストワッシャ５が摩耗しやすくなっている。 In the case of planetary gear speed reducers mounted on automobiles, the use of high-speed rotation of planetary gears is increasing due to higher performance of automobiles, and the planetary gears are designed to have a torsion angle in terms of strength. The PV value of the thrust washer 5 is high, and the thrust washer 5 is easily worn.
【０００４】 また、総ころタイプの場合、遊星歯車１のスラスト力により、ころ６にモーメ ント荷重がかかるのでスキューが発生し、これによりころ６のスラスト力が大き くなり、ころ端面と接触するスラストワッシャ５が摩耗しやすい。Further, in the case of the full-roller type, the thrust force of the planetary gear 1 applies a moment load to the roller 6 to cause skew, which increases the thrust force of the roller 6 and makes contact with the roller end surface. Thrust washer 5 is easily worn.
【０００５】 更に、総ころタイプの場合、許容回転数が低いため、高速回転使用においては 発熱に伴う潤滑油の温度上昇により、潤滑不足を来たしやすい問題もある。Further, in the case of the full-roller type, since the permissible rotational speed is low, there is a problem that in high-speed rotation use, insufficient lubrication easily occurs due to a temperature rise of the lubricating oil due to heat generation.
【０００６】 そこで、この考案は上記の問題点を解決するため、スラストワッシャと一体化 された針状ころ軸受の保持器を提供することを課題とする。In order to solve the above problems, it is an object of the present invention to provide a needle roller bearing retainer integrated with a thrust washer.
【０００７】[0007]
上記の課題を解決するために、この考案はポケットを周方向に一定間隔で形成 した保持器本体の両端に、外方へ張り出したスラストワッシャ部を一体に設けた 構成としたものである。 In order to solve the above-mentioned problems, the present invention has a structure in which thrust washer portions projecting outward are integrally provided at both ends of a retainer body having pockets formed at regular intervals in the circumferential direction.
【０００８】[0008]
上記の保持器を用いた針状ころ軸受は、保持器本体のポケットにころを挿入し てその姿勢の安定化を図ると共に、スラストワッシャ部においてスラスト力を受 ける。保持器と一体のスラストワッシャ部は、遊星歯車の回転数の約１／２とな る。 In the needle roller bearing using the above cage, the roller is inserted in the pocket of the cage body to stabilize its posture, and the thrust washer receives thrust force. The thrust washer part integrated with the cage is about 1/2 of the rotation speed of the planetary gear.
【０００９】[0009]
図１に示すように、実施例の保持器７は、環状の保持器本体８と、その保持器 本体８の両端に外方へ張り出した環状のスラストワッシャ部９、９’とから成り 、上記保持器本体７には周方向に一定間隔をおいて所要数のポケット１０が設け られる。上記の保持器７は図２に示すように、一方のスラストワッシャ部９’を 保持器本体８から分離して２ピースの部材に分けて構成しておくと組立時に便利 である。この場合該スラストワッシャ部９’の内周面には、保持器本体８の各柱 １１に合致する溝１２が設けてあり、組立後溶接等により一体化される。 As shown in FIG. 1, the retainer 7 of the embodiment comprises an annular retainer body 8 and annular thrust washer portions 9 and 9 ′ protruding outward at both ends of the retainer body 8. The cage body 7 is provided with a required number of pockets 10 at regular intervals in the circumferential direction. As shown in FIG. 2, the cage 7 is convenient for assembling when one thrust washer portion 9'is separated from the cage body 8 and divided into two pieces. In this case, on the inner peripheral surface of the thrust washer portion 9 ', there are provided grooves 12 which match the columns 11 of the retainer body 8 and are integrated by welding or the like after assembly.
【００１０】 図３は、上記の保持器７を用いた針状ころ軸受４’を遊星歯車１の支持装置に 使用した例である。この支持装置は、前述の従来の場合と同様の左右一対のキャ リア２、２の間に固定した軸３に上述の保持器７のポケット１０にころ６を挿入 してなる針状ころ軸受４’を介して遊星歯車１を支持する。保持器７の各ワッシ ャ部９、９’はころ６及び遊星歯車１との各両端面と、各キャリア２、２との間 に介在される。FIG. 3 shows an example in which the needle roller bearing 4 ′ using the cage 7 is used as a support device for the planetary gear 1. This support device has a needle roller bearing 4 in which a roller 6 is inserted into a pocket 10 of the cage 7 on a shaft 3 fixed between a pair of left and right carriers 2 and 2 similar to the conventional case. 'To support the planetary gear 1. The washer portions 9 and 9'of the cage 7 are interposed between the respective end surfaces of the roller 6 and the planetary gear 1 and the respective carriers 2 and 2.
【００１１】 上記の支持装置を組立てる場合は、保持器８として、図２に示したように、一 方のスラストワッシャ部９’を分離した２ピースのものを用い、一方のキャリア ２を外した状態で軸３のまわりに保持器本体８（及びこれと一体のスラストワッ シャ部９）とを挿入したのち、各ポケット１０にころ６を挿入し、そのまわりに 遊星歯車１を組入れ、その後保持器本体８の各柱１１の一端に、分離されたスラ ストワッシャ部９’の溝１２を嵌合し、その嵌合部分を溶接して一体化する。In the case of assembling the above supporting device, as the retainer 8, as shown in FIG. 2, a two-piece one in which one thrust washer portion 9 ′ is separated is used, and one carrier 2 is removed. After inserting the cage main body 8 (and the thrust washer portion 9 integral therewith) around the shaft 3 in this state, the rollers 6 are inserted into the respective pockets 10, and the planetary gear 1 is assembled around the cage 6, and then the cage is inserted. The groove 12 of the separated thrust washer portion 9'is fitted to one end of each pillar 11 of the main body 8 and the fitted portion is welded to be integrated.
【００１２】 上記の支持装置において、スラストワッシャ部９、９’は保持器本体８と一体 に回転し、その回転数は遊星歯車１の回転数の約１／２となる。その結果各スラ ストワッシャ部９、９’と遊星歯車１の端面及び各スラストワッシャ部９、９’ とキャリア２、２との間の回転もそれぞれ約１／２となるので、各スラストワッ シャ部９、９’のＰＶ値が半減する。またころ６の姿勢は保持器７のポケット１ ０の部分で保持され、スキューが防止される。In the above support device, the thrust washer portions 9 and 9 ′ rotate integrally with the retainer body 8, and the rotation speed thereof is about half the rotation speed of the planetary gear 1. As a result, the rotation between the thrust washer portions 9 and 9'and the end surface of the planetary gear 1 and between the thrust washer portions 9 and 9'and the carriers 2 and 2 is also about 1/2, so that each thrust washer portion 9 , 9 ′ PV value is halved. Further, the posture of the roller 6 is held by the pocket 10 portion of the cage 7, and skew is prevented.
【００１３】[0013]
以上のように、この考案は保持器本体の両端に外方へ張り出したスラストワッ シャ部を一体に設けたことにより、スラストワッシャ部のＰＶ値を半減させるこ とができ、またころの姿勢が安定するためにそのスキューを防止し、ころ端面と 接触する部分における摩耗を低減することができる。また、許容回転数が総ころ タイプに比べ約２倍に増えるので、発熱が低く、又寿命低下を抑えることができ る。 As described above, according to the present invention, since the thrust washer portions projecting outward are integrally provided at both ends of the cage body, the PV value of the thrust washer portion can be halved, and the posture of the roller is stable. Therefore, the skew can be prevented, and the wear at the portion contacting the roller end face can be reduced. In addition, the allowable number of rotations is about double that of the full-roller type, so heat generation is low and the life can be suppressed.
