Description

この発明は、ハウジングに固定されるプレート一体型の転がり軸受に関する。詳しくは、自動車用トランスミッション等に使用され、そのハウジングに固定されるプレート一体型転がり軸受に関する。   The present invention relates to a plate-integrated rolling bearing fixed to a housing. More specifically, the present invention relates to a plate-integrated rolling bearing used in an automobile transmission and the like and fixed to the housing.

近年、自動車の小型化に伴い、エンジンやトランスミッション等の小型化要求が強まっている。このため、構成部品のコンパクト化が種々検討されており、転がり軸受のハウジングへの固定方法についても、検討が行われている。   In recent years, with the miniaturization of automobiles, there is an increasing demand for miniaturization of engines and transmissions. For this reason, various attempts have been made to make the components compact, and a method for fixing the rolling bearing to the housing has also been studied.

転がり軸受のハウジングへの固定方法として、転がり軸受の外輪に段部を設け、固定プレートで、この段部とハウジングを挟み込み、固定する方法が知られている（特許文献１）。
また、ハウジングに固定されるプレートに転がり軸受を固定するため、係止環を用いる方法が知られている（特許文献２）。
さらに、ハウジングに固定するプレートの中に形成した貫通孔に転がり軸受を挿入し、プレートと転がり軸受を非貫通で金属を変形させて固定する方法が知られている（特許文献３）。 As a method for fixing the rolling bearing to the housing, a method is known in which a step portion is provided on the outer ring of the rolling bearing, and the step portion and the housing are sandwiched and fixed by a fixing plate (Patent Document 1).
Further, a method using a locking ring for fixing a rolling bearing to a plate fixed to a housing is known (Patent Document 2).
Furthermore, a method is known in which a rolling bearing is inserted into a through-hole formed in a plate that is fixed to the housing, and the plate and the rolling bearing are fixed by deforming a metal without penetrating (Patent Document 3).

特開２００９−００８１５５号公報JP 2009-008155 A 特開２００９−０３０７９４号公報JP 2009-030794 A ＤＥ１０２００８０２１８３２Ｂ３DE102008021832B3

しかしながら、特許文献１に記載の方法は、ハウジングの小型化は可能であるが、一対のプレートを用い、ボルトにより固定するので、ハウジングへの組付性は、従来とそれほど変わらない。また、特許文献２に記載の方法は、プレートを軸受と一体とするべく、プレートと軸受外輪の間に係止環を設けることで、プレートと軸受の抜け止めを図っており、組付性が向上しているが、部品点数が増えるので、作業性に問題が生じる場合がある。さらに、特許文献３に記載の方法は、固定されているか否かの確認を行いにくい。   However, although the method described in Patent Document 1 can reduce the size of the housing, since it uses a pair of plates and is fixed by bolts, the assembling property to the housing is not much different from the conventional one. In addition, the method described in Patent Document 2 is designed to prevent the plate and the bearing from coming off by providing a locking ring between the plate and the bearing outer ring so that the plate is integrated with the bearing. Although improved, the number of parts increases, which may cause problems in workability. Furthermore, it is difficult to confirm whether the method described in Patent Document 3 is fixed or not.

そこで、この発明は、固定プレートと軸受の一体化およびハウジングへの取付性を向上させ、かつ作業性を向上させることを目的とする。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to improve the integration of the fixed plate and the bearing, the mounting property to the housing, and the workability.

以下、図１〜図５に基づき、この発明の実施形態を説明する。
この発明に係るプレート一体型転がり軸受１０は、図２（ａ）に示すように、ハウジング３１（図５参照）に固定するためのプレート１１（図１（ａ）〜（ｃ）参照）と、転がり軸受２１とを一体化したものである。 Hereinafter, embodiments of the present invention will be described with reference to FIGS.
A plate-integrated rolling bearing 10 according to the present invention includes a plate 11 (see FIGS. 1A to 1C) for fixing to a housing 31 (see FIG. 5), as shown in FIG. The rolling bearing 21 is integrated.

プレート１１は、図１（ａ）に示すように、軸受配置孔１２及びボルト用穴１３を有する。この軸受配置孔１２は、転がり軸受２１を配置するための孔である。軸受配置孔１２は、転がり軸受２１の外周に嵌合する円形の孔である。軸受配置孔１２は、プレート１１を貫通して形成されている。ボルト用穴１３は、このプレート１１をハウジング３１に取り付けて固定するため、ボルト３２（図５参照）を通し、締め付けるための穴である。ボルト用穴１３は、雌ねじを内周に有するねじ孔である。プレート１１は、外力を加えることで塑性変形可能な金属で形成されている。
そして、このプレート１１の軸受配置孔１２の周縁部は、このプレート１１と転がり軸受２１とをかしめ結合するかしめ手段を有する。 The plate 11 has a bearing arrangement hole 12 and a bolt hole 13 as shown in FIG. The bearing arrangement hole 12 is a hole for arranging the rolling bearing 21. The bearing arrangement hole 12 is a circular hole that fits on the outer periphery of the rolling bearing 21. The bearing arrangement hole 12 is formed through the plate 11. The bolt hole 13 is a hole through which a bolt 32 (see FIG. 5) is passed and tightened in order to attach and fix the plate 11 to the housing 31. The bolt hole 13 is a screw hole having an internal thread on the inner periphery. The plate 11 is made of a metal that can be plastically deformed by applying an external force.
And the peripheral part of the bearing arrangement hole 12 of this plate 11 has a caulking means for caulking and coupling the plate 11 and the rolling bearing 21.

このかしめ手段の例としては、このプレート１１の軸受配置孔１２の周縁部の少なくとも２箇所に設けられた貫通孔１４ｂと、軸受配置孔１２と貫通孔１４ｂの間に形成されるかしめ部１４ａからなるかしめ手段１４をあげることができる。   Examples of the caulking means include a through hole 14b provided in at least two positions on the peripheral edge of the bearing arrangement hole 12 of the plate 11, and a caulking part 14a formed between the bearing arrangement hole 12 and the through hole 14b. The staking means 14 can be raised.

貫通孔１４ｂは、図１（ａ）に示すように軸方向に見て、軸受配置孔１２の周方向に長い長孔とされている。ここで、貫通孔１４ｂの軸受配置孔１２の周方向に沿った方向の幅寸法は、貫通孔１４ｂの軸受配置孔１２の半径方向に沿った方向の幅寸法よりも長い。   As shown in FIG. 1A, the through hole 14 b is a long hole that is long in the circumferential direction of the bearing arrangement hole 12 when viewed in the axial direction. Here, the width dimension of the through hole 14b in the direction along the circumferential direction of the bearing arrangement hole 12 is longer than the width dimension of the through hole 14b in the direction along the radial direction of the bearing arrangement hole 12.

図１（ｃ）に示すように、かしめ部１４ａは、軸受配置孔１２と貫通孔１４ｂの間に形成されたプレート１１の実体部分である。このかしめ部１４ａは、プレート１１のかしめ部１４ａ以外の部分と継ぎ目の無い一体に形成され、軸受配置孔１２の中心方向（すなわち軸受配置孔１２の径方向内方）に向かって塑性変形可能である。すなわち、貫通孔１４ｂに治具等を挿入し、図２（ｃ）および図４に示すようにかしめ部１４ａに押圧力を加えることにより、図２（ｂ）および図３に示すようにかしめ部１４ａが軸受配置孔１２の中心方向に向かって塑性変形するようになっている。   As shown in FIG. 1C, the caulking portion 14a is a substantial part of the plate 11 formed between the bearing arrangement hole 12 and the through hole 14b. The caulking portion 14a is integrally formed with the portions other than the caulking portion 14a of the plate 11 without any joints, and can be plastically deformed toward the center direction of the bearing arrangement hole 12 (that is, radially inward of the bearing arrangement hole 12). is there. That is, by inserting a jig or the like into the through hole 14b and applying a pressing force to the caulking portion 14a as shown in FIGS. 2 (c) and 4, a caulking portion as shown in FIG. 2 (b) and FIG. 14 a is plastically deformed toward the center of the bearing arrangement hole 12.

図４に示すように、貫通孔１４ｂは、かしめ部１４ａの側に凸円弧状の孔縁１５を有する。かしめ部１４ａは、その幅寸法（軸受配置孔１２の半径方向の寸法）が周方向の中央の位置で最も大きい形状とされている。貫通孔１４ｂに凸円弧状の孔縁１５を設けることにより、かしめ部１４ａを径方向内方に塑性変形させたときに、かしめ部１４ａが円滑に変形するようになっている。   As shown in FIG. 4, the through hole 14b has a convex arcuate hole edge 15 on the caulking portion 14a side. The caulking portion 14a has a shape having the largest width dimension (the dimension in the radial direction of the bearing arrangement hole 12) at the center position in the circumferential direction. By providing a convex arcuate hole edge 15 in the through hole 14b, the caulking portion 14a is smoothly deformed when the caulking portion 14a is plastically deformed radially inward.

図１（ｂ）に示すように、かしめ部１４ａは、プレート１１のかしめ部１４ａ以外の部分よりも薄く形成されている。すなわち、プレート１１の軸受配置孔１２の内周部分のうち、かしめ部１４ａの部分の軸方向厚さは、かしめ部１４ａ以外の部分の軸方向厚さよりも薄い。これにより、プレート１１の全体としての剛性を確保しつつ、かしめ部１４ａの部分を塑性変形させることを容易としている。また、かしめ部１４ａの部分の軸方向厚さは、図２（ｂ）に示すように、かしめ部１４ａが転がり軸受２１の外輪２５の段部２６に嵌り込むように段部２６（円周溝）の軸方向幅寸法よりも小さく設定されている。   As shown in FIG. 1B, the caulking portion 14a is formed thinner than the portion of the plate 11 other than the caulking portion 14a. That is, the axial thickness of the caulking portion 14a in the inner peripheral portion of the bearing arrangement hole 12 of the plate 11 is thinner than the axial thickness of the portion other than the caulking portion 14a. This facilitates plastic deformation of the caulking portion 14a while securing the rigidity of the plate 11 as a whole. Further, as shown in FIG. 2B, the axial thickness of the caulking portion 14a is set such that the caulking portion 14a fits into the step portion 26 of the outer ring 25 of the rolling bearing 21 (circumferential groove). ) In the axial width dimension.

プレート１１のかしめ部１４ａ以外の部分の肉厚に対するかしめ部１４ａの肉厚の比は、１／２以下が好ましく、１／３以下が好ましい。このようにすることによって、塑性変形を容易に行うことができる。一方、この肉厚の比は、１／２０以上がよく、１／１０以上が好ましい。これ以上薄いと、前記のかしめ結合により、転がり軸受２１を固定することが不十分になる場合がある。   The ratio of the thickness of the caulking portion 14a to the thickness of the portion other than the caulking portion 14a of the plate 11 is preferably 1/2 or less, and preferably 1/3 or less. By doing in this way, plastic deformation can be performed easily. On the other hand, the thickness ratio is preferably 1/20 or more, and preferably 1/10 or more. If it is thinner than this, it may be insufficient to fix the rolling bearing 21 due to the caulking connection.

このかしめ手段１４は、プレート１１の軸受配置孔１２の周縁部に等間隔に設けることが好ましい。具体的には、２箇所に設けられる場合は、相対する位置、すなわち、軸受配置孔の中心を中心としたとき、２つのかしめ手段１４が配される位置の角度を１８０°とする位置が好ましい。また、３箇所に設ける場合は、軸受配置孔の中心を中心としたとき、３つのかしめ手段１４が配される位置の角度をそれぞれ１２０°とする位置が好ましい。この位置とすることにより、後述するように、かしめ手段１４により、転がり軸受２１をかしめて固定する際、転がり軸受２１を均等に締め付けることができ、転がり軸受２１の位置が偏ってしまうおそれを回避することができる。   The caulking means 14 is preferably provided at equal intervals on the peripheral edge of the bearing arrangement hole 12 of the plate 11. Specifically, in the case of being provided at two places, a position where the opposite position, that is, the position at which the two caulking means 14 are arranged when the center of the bearing arrangement hole is the center is 180 ° is preferable. . Moreover, when providing in three places, when making the center of a bearing arrangement | positioning hole into the center, the position which makes the angle of the position where the three crimping means 14 are arrange | positioned each 120 degrees is preferable. By adopting this position, as will be described later, when the rolling bearing 21 is caulked and fixed by the caulking means 14, the rolling bearing 21 can be evenly tightened, and the risk that the position of the rolling bearing 21 is biased is avoided. can do.

転がり軸受２１は、図２（ａ）に示すように、複数の転動体２２、この転動体２２を保持する保持器２３、内輪２４及び外輪２５とを備えた軸受である。内輪２４と外輪２５は、内輪２４の外周と外輪２５の内周が径方向に対向するように同軸に配置され、内輪２４と外輪２５の対向面間に転動体２２が組み込まれている。転動体２２は、例えば玉である。   As shown in FIG. 2A, the rolling bearing 21 is a bearing including a plurality of rolling elements 22, a cage 23 that holds the rolling elements 22, an inner ring 24, and an outer ring 25. The inner ring 24 and the outer ring 25 are arranged coaxially so that the outer circumference of the inner ring 24 and the inner circumference of the outer ring 25 are opposed to each other in the radial direction, and a rolling element 22 is incorporated between opposing surfaces of the inner ring 24 and the outer ring 25. The rolling elements 22 are balls, for example.

外輪２５には、図２（ｃ）に示すように、その外周面の角部に、プレート１１の軸受配置孔１２の周縁部を配する段部２６を有する。段部２６は、外輪２５の外周の円筒面に対して径方向内方に凹んだ部分である。ここでは、段部２６は、外輪２５の外周面の軸方向端部に形成された円周溝とされている。円周溝の軸方向両側の溝縁２７，２８のうち、外輪２５の軸方向端面の側の溝縁２８は、他方の溝縁２７よりも低く形成されている。このようにすると、図２（ｂ）に示すように、プレート１１のかしめ部１４ａが段部２６の内面に接触した状態で、プレート１１のかしめ部１４ａと段部２６のかかり代（軸方向に見てかしめ部１４ａと外輪２５が重なり合う部分の大きさ）を確保することが可能となる。   As shown in FIG. 2 (c), the outer ring 25 has a stepped portion 26 for arranging the peripheral edge portion of the bearing arrangement hole 12 of the plate 11 at the corner portion of the outer peripheral surface thereof. The step portion 26 is a portion that is recessed radially inward with respect to the cylindrical surface on the outer periphery of the outer ring 25. Here, the step portion 26 is a circumferential groove formed at the axial end portion of the outer peripheral surface of the outer ring 25. Of the groove edges 27 and 28 on both sides in the axial direction of the circumferential groove, the groove edge 28 on the axial end face side of the outer ring 25 is formed lower than the other groove edge 27. In this way, as shown in FIG. 2 (b), in the state where the caulking portion 14a of the plate 11 is in contact with the inner surface of the step portion 26, the margin of the caulking portion 14a and the step portion 26 of the plate 11 (in the axial direction) It is possible to ensure the size of the portion where the caulking portion 14a and the outer ring 25 overlap.

図２（ｂ）に示すように、段部２６として、外輪２５の軸方向端面の側の溝縁２８を有する円周溝を採用すると、外輪２５をプレート１１に対して軸方向に確実に固定することが可能であるが、段部２６として、外輪２５の軸方向端面の側の溝縁２８をもたないもの（すなわち、段部２６の内面が外輪２５の軸方向端面に交差する形状のもの）を採用することも可能である。   As shown in FIG. 2B, when a circumferential groove having a groove edge 28 on the axial end face side of the outer ring 25 is employed as the step portion 26, the outer ring 25 is securely fixed to the plate 11 in the axial direction. However, the step portion 26 does not have the groove edge 28 on the axial end surface side of the outer ring 25 (that is, the inner surface of the step portion 26 intersects the axial end surface of the outer ring 25). Can also be adopted.

次に、転がり軸受２１をハウジング３１に固定する方法について、図２〜図４を用いて説明する。   Next, a method for fixing the rolling bearing 21 to the housing 31 will be described with reference to FIGS.

まず、図２（ｃ）および図４に示すように、転がり軸受２１の外輪２５の段部２６に、プレート１１の軸受配置孔１２の周縁部を配する。次に、図２（ｂ）および図３に示すように、貫通孔１４ｂに治具（図示せず）を挿入し、その治具でかしめ部１４ａを軸受配置孔１２の中心方向に向かって押圧する。これにより、かしめ部１４ａは、塑性変形を生じ、軸受配置孔１２の中心方向に移動する。そして、塑性変形されたかしめ部１４ａは、転がり軸受２１の外輪２５の段部２６の内側の円筒面に押しつけられた状態となる。これにより、プレート１１と転がり軸受２１はかしめ結合され、両者が一体化する。   First, as shown in FIG. 2C and FIG. 4, the peripheral portion of the bearing arrangement hole 12 of the plate 11 is arranged on the step portion 26 of the outer ring 25 of the rolling bearing 21. Next, as shown in FIGS. 2B and 3, a jig (not shown) is inserted into the through hole 14 b and the caulking portion 14 a is pressed toward the center of the bearing arrangement hole 12 with the jig. To do. As a result, the caulking portion 14 a undergoes plastic deformation and moves toward the center of the bearing arrangement hole 12. The plastically deformed caulking portion 14 a is pressed against the cylindrical surface inside the step portion 26 of the outer ring 25 of the rolling bearing 21. As a result, the plate 11 and the rolling bearing 21 are caulked and joined together.

ここで、かしめ部１４ａを径方向内方に塑性変形させるに際し、図１に示す複数箇所（この実施形態では２箇所）のかしめ部１４ａを同時にかしめると好ましい。このようにすると、かしめ部１４ａをかしめるときに、複数箇所のかしめ部１４ａから外輪２５に均一に押圧力が作用するので、外輪２５の中心が軸受配置孔１２の中心から片寄ってしまう事態を効果的に防止することができ、外輪２５の中心が軸受配置孔１２の中心に一致しやすくなる。また、複数箇所のかしめ部１４ａを同時にかしめると、かしめの工程数を一工程に抑えることができるため、製造ラインの設計も容易である。   Here, when the caulking portion 14a is plastically deformed inward in the radial direction, it is preferable that the caulking portions 14a shown in FIG. 1 (two in this embodiment) are caulked simultaneously. In this way, when the caulking portion 14a is caulked, a pressing force is uniformly applied to the outer ring 25 from a plurality of caulking portions 14a, so that the center of the outer ring 25 is offset from the center of the bearing arrangement hole 12. Therefore, the center of the outer ring 25 can easily coincide with the center of the bearing arrangement hole 12. In addition, if the caulking portions 14a at a plurality of locations are caulked at the same time, the number of caulking steps can be suppressed to one step, so that the production line can be designed easily.

このようにして得られたプレート一体型転がり軸受１０は、図５に示すように、ハウジング３１にセットし、プレート１１のボルト用穴１３を通して、ボルト３２を用いてプレート一体型転がり軸受１０をハウジング３１に固定させることができる。   As shown in FIG. 5, the plate-integrated rolling bearing 10 obtained in this way is set in a housing 31, and the plate-integrated rolling bearing 10 is installed in the housing using bolts 32 through bolt holes 13 of the plate 11. 31 can be fixed.

このようにして得られたプレート一体型転がり軸受１０は、トランスミッションや、自動車用モータ、コンプレッサ等に使用される転がり軸受の少なくとも一つとして用いることができる。   The plate-integrated rolling bearing 10 thus obtained can be used as at least one of rolling bearings used in transmissions, automobile motors, compressors, and the like.

トランスミッションの例としては、図６に示されるトランスミッションを例としてあげることができる。このトランスミッションは、段階的に変速比を変化させる多段変速機になっており、その回転部（例えば入力軸Ｓ１および出力軸Ｓ２）を回転可能に支持するプレート付き転がり軸受Ｂとして、上記のプレート一体型転がり軸受１０を備えている。図示のトランスミッションは、エンジンの回転が入力される入力軸Ｓ１と、入力軸Ｓ１と平行に設けられた出力軸Ｓ２と、入力軸Ｓ１から出力軸Ｓ２に回転を伝達する複数のギア列Ｇ１〜Ｇ４と、各ギア列Ｇ１〜Ｇ４と入力軸Ｓ１または出力軸Ｓ２との間に組み込まれた図示しないクラッチとを有し、そのクラッチを選択的に係合させることで使用するギア列Ｇ１〜Ｇ４を切り替え、これにより、入力軸Ｓ１から出力軸Ｓ２に伝達する回転の変速比を変化させるものである。出力軸Ｓ２の回転は出力ギアＧ５に出力され、その出力ギアＧ５の回転がディファレンシャルギヤ等に伝達される。入力軸Ｓ１と出力軸Ｓ２は、それぞれプレート一体型転がり軸受１０で回転可能に支持されている。   As an example of the transmission, the transmission shown in FIG. 6 can be given as an example. This transmission is a multi-stage transmission in which the gear ratio is changed stepwise, and the above-described plate is used as a rolling bearing B with a plate that rotatably supports its rotating parts (for example, the input shaft S1 and the output shaft S2). A body type rolling bearing 10 is provided. The illustrated transmission includes an input shaft S1 to which engine rotation is input, an output shaft S2 provided in parallel with the input shaft S1, and a plurality of gear trains G1 to G4 that transmit the rotation from the input shaft S1 to the output shaft S2. Each of the gear trains G1 to G4 and a clutch (not shown) incorporated between the input shaft S1 or the output shaft S2, and the gear trains G1 to G4 used by selectively engaging the clutches. This changes the speed ratio of the rotation transmitted from the input shaft S1 to the output shaft S2. The rotation of the output shaft S2 is output to the output gear G5, and the rotation of the output gear G5 is transmitted to the differential gear or the like. The input shaft S1 and the output shaft S2 are rotatably supported by the plate-integrated rolling bearing 10, respectively.
