Description

本発明は、ハウジングに固定される軌道輪の凹円弧状の軌道面に複数のころを配列し、可動部材の凸円弧状部を揺動自在に支持する揺動軸受に関する。   The present invention relates to a rocking bearing in which a plurality of rollers are arranged on a concave arc-shaped raceway surface of a bearing ring fixed to a housing, and a convex arc-shaped portion of a movable member is swingably supported.

建設機械や農業機械等に使用される斜板式の油圧ポンプや油圧モータ等には、斜板等の可動部材を揺動自在に支持する揺動軸受が組み込まれている。この種の揺動軸受の一例を図５（ａ）、（ｂ）に示す（特許文献１参照。）。この揺動軸受は、ハウジング１１に固定される軌道輪１の凹円弧状の軌道面１ａに複数のころ２を保持器３に保持して配列し、その複数のころ２で斜板等の可動部材１２の凸円弧状部１２ａを揺動自在に支持するものである。その軌道輪１は、凸円弧状の外径面１ｂをハウジング１１の凹円弧状部１１ａに当接させ、外径面１ｂの周方向中心位置から垂直に突出させたピン突起５１を、ハウジング１１の凹円弧状部１１ａに設けられたピン穴５２に係合させることにより、ハウジング１１の凹円弧状部１１ａに位置決めされている。なお、このピン突起５１は通常エンボス加工により形成されており、これに伴って軌道面１ａには凹部５３が形成されている。
特開２００２−２８６０４１号公報（図２） A swash plate type hydraulic pump, a hydraulic motor, or the like used in construction machinery, agricultural machinery, or the like incorporates a swing bearing that supports a movable member such as a swash plate in a swingable manner. An example of this type of rocking bearing is shown in FIGS. 5A and 5B (see Patent Document 1). In this oscillating bearing, a plurality of rollers 2 are arranged on a concave arc-shaped raceway surface 1 a of a raceway ring 1 fixed to a housing 11 while being held by a cage 3, and the swash plate or the like is movable by the plurality of rollers 2. The convex arcuate portion 12a of the member 12 is supported in a swingable manner. The bearing ring 1 has a pin projection 51, which has a convex arc-shaped outer diameter surface 1 b in contact with a concave arc-shaped portion 11 a of the housing 11 and projects vertically from the circumferential center position of the outer diameter surface 1 b. The concave arc-shaped portion 11a of the housing 11 is positioned by engaging with a pin hole 52 provided in the concave arc-shaped portion 11a. In addition, this pin protrusion 51 is normally formed by embossing, and the recessed part 53 is formed in the track surface 1a in connection with this.
Japanese Patent Laying-Open No. 2002-286041 (FIG. 2)

ところで、上記のように軌道輪外径面の周方向中心位置から垂直に突出するピン突起で軌道輪を位置決めする揺動軸受は、図６（ａ）に示すように、ハウジング１１の凹円弧状部１１ａの曲率半径ＲＨが軌道輪１の外径面１ｂの曲率半径ＲＬよりも大きく、軌道輪１の外径面１ｂが周方向中心部でハウジング１１の凹円弧状部１１ａと接触する場合に、図６（ｂ）に示すように、軌道輪１がハウジング１１のピン穴５２と係合するピン突起５１の回りに動きやすく、可動部材の凸円弧状部を組み付けにくい問題がある。なお、凹円弧状部１１ａの曲率半径ＲＨが軌道輪外径面１ｂの曲率半径ＲＬよりも小さく、軌道輪外径面１ｂが周方向両端部で凹円弧状部１１ａと接触する場合は、軌道輪１が動くことなく安定するので、このような問題はない。 By the way, as shown in FIG. 6 (a), the rocking bearing for positioning the raceway ring by the pin projection vertically projecting from the circumferential center position of the raceway outer diameter surface as shown in FIG. The radius of curvature RH of the portion 11a is larger than the radius of curvature RL of the outer diameter surface 1b of the bearing ring 1, and the outer diameter surface 1b of the race ring 1 contacts the concave arcuate portion 11a of the housing 11 at the circumferential center. In this case, as shown in FIG. 6B, there is a problem that the race 1 is easy to move around the pin protrusion 51 that engages with the pin hole 52 of the housing 11, and it is difficult to assemble the convex arcuate portion of the movable member. When the radius of curvature RH of the concave arcuate portion 11a is smaller than the radius of curvature RL of the raceway outer diameter surface 1b, and the raceway outer diameter surface 1b contacts the concave arcuate portion 11a at both ends in the circumferential direction. Since the race 1 is stabilized without moving, there is no such problem.

本発明の課題は、揺動軸受の軌道輪が外径面の周方向中心部でハウジングの凹円弧状部と接触する場合であっても、ハウジングに位置決めした軌道輪が動かないようにすることである。   An object of the present invention is to prevent a bearing ring positioned on a housing from moving even when the bearing ring of the rocking bearing is in contact with the concave arc-shaped portion of the housing at the circumferential center of the outer diameter surface. It is.

上記の課題を解決するため、本発明は、内径面に凹円弧状の軌道面が設けられ、外径面が凸円弧状に形成された軌道輪と、この軌道輪の軌道面に配列されて転動する複数のころとを備え、前記軌道輪がその外径面をハウジングの凹円弧状部に当接させた状態でハウジングに固定され、前記複数のころで可動部材の凸円弧状部を揺動自在に支持する揺動軸受において、前記軌道輪の外径面にキー溝を設け、この軌道輪のキー溝と前記ハウジングの凹円弧状部に設けられたキー溝とにキーを係合させることにより、前記軌道輪が前記ハウジングの凹円弧状部に位置決めされるようにした構成を採用した。   In order to solve the above-described problems, the present invention provides a raceway having a concave arc-shaped raceway surface on an inner diameter surface and an outer diameter surface formed in a convex arc shape, and is arranged on the raceway surface of the raceway. A plurality of rollers for rolling, and the raceway ring is fixed to the housing in a state where an outer diameter surface thereof is in contact with the concave arcuate portion of the housing, and the convex arcuate portion of the movable member is formed by the plurality of rollers. In a rocking bearing that is swingably supported, a key groove is provided on the outer diameter surface of the bearing ring, and a key is engaged with the key groove of the bearing ring and the key groove provided in the concave arcuate portion of the housing. By adopting such a configuration, the configuration is adopted in which the race is positioned in the concave arcuate portion of the housing.

すなわち、軌道輪外径面のキー溝とハウジングの凹円弧状部のキー溝とにキーを係合させて、軌道輪のハウジングへの位置決めを行うことにより、軌道輪が外径面の周方向中心部でハウジングの凹円弧状部と接触する場合でも、キーと各キー溝との係合によって、軌道輪の動きを拘束できるようにしたのである。   That is, by engaging the key with the key groove on the outer ring surface of the bearing ring and the key groove on the concave arcuate portion of the housing and positioning the bearing ring on the housing, the bearing ring moves in the circumferential direction of the outer diameter surface. Even when contacting the concave arcuate portion of the housing at the center, the movement of the raceway can be restricted by the engagement between the key and each keyway.

また、前記軌道輪のキー溝は、前記軌道面へ貫通しないものとすることが望ましい。従来の揺動軸受では、ころが軌道面の凹部上を転動するときに凹部の周縁部に過大な面圧が発生するため、軌道輪の早期剥離を生じる場合があるが、上記の構成において、軌道輪のキー溝を軌道面へ貫通させなければ、軌道面に過大面圧が発生する部位がなくなり、軌道輪の早期剥離を防止できるからである。   It is desirable that the keyway of the raceway does not penetrate the raceway surface. In the conventional rocking bearing, when the roller rolls on the concave portion of the raceway surface, an excessive surface pressure is generated at the peripheral portion of the concave portion. This is because if the keyway of the raceway is not penetrated into the raceway surface, there is no portion where excessive surface pressure is generated on the raceway surface, and early separation of the raceway ring can be prevented.

本発明の揺動軸受は、上述したように、軌道輪外径面のキー溝とハウジングの凹円弧状部のキー溝とにキーを係合させて、軌道輪の位置決めを行うようにしたものであるから、軌道輪が外径面の周方向中心部でハウジングの凹円弧状部と接触する場合でも、軌道輪の動きを拘束でき、可動部材の凸円弧状部を容易に組み付けることができる。   As described above, the rocking bearing of the present invention is such that the key is engaged with the key groove on the outer surface of the race ring and the key groove on the concave arcuate portion of the housing to position the race ring. Therefore, even when the raceway is in contact with the concave arcuate portion of the housing at the circumferential center of the outer diameter surface, the movement of the raceway can be restricted and the convex arcuate portion of the movable member can be easily assembled. .

また、前記軌道輪のキー溝を軌道面へ貫通しないように形成することにより、軌道面に従来のような凹部がなくなり、軌道輪の早期剥離を防止することができる。   Also, by forming the keyway of the raceway so as not to penetrate the raceway surface, there is no conventional recess in the raceway surface, and early separation of the raceway ring can be prevented.

以下、図１乃至図４に基づき、本発明の実施形態を説明する。図１および図２は、第１の実施形態を示す。この揺動軸受は、図１（ａ）に示すように、内径面に凹円弧状の軌道面１ａが設けられ、外径面１ｂが凸円弧状に形成された軌道輪１と、軌道輪１の軌道面１ａに配列されて転動する複数のころ２と、これらのころ２を転動自在に保持する保持器３とからなり、軌道輪１がその外径面１ｂをハウジング１１の凹円弧状部１１ａに当接させた状態でハウジング１１に固定され、複数のころ２で可動部材１２の凸円弧状部１２ａを揺動自在に支持するようになっている。   Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 4. 1 and 2 show a first embodiment. As shown in FIG. 1 (a), this oscillating bearing has a raceway ring 1 in which a concave arc-shaped raceway surface 1a is provided on an inner diameter surface and an outer diameter surface 1b is formed in a convex arc shape, and a raceway ring 1 A plurality of rollers 2 which are arranged on the raceway surface 1a and roll, and a cage 3 which holds these rollers 2 so that they can roll. The raceway ring 1 has an outer diameter surface 1b which is a concave circle of the housing 11. It is fixed to the housing 11 in contact with the arcuate portion 11a, and the plurality of rollers 2 support the convex arcuate portion 12a of the movable member 12 in a swingable manner.

前記軌道輪１は、鋼板のプレス成形品とされ、図１（ｂ）および図２（ａ）に示すように、軌道面１ａの軸方向両端部に、ころ２の軸方向移動を規制する鍔４がフランジ曲げ加工で形成されている。なお、軌道輪の鍔は、図５に示した従来例と同様に、軌道面の軸方向両端部のいずれか一方のみに設けるようにしてもよい。また、軌道面１ａの周方向両端部には、保持器３の揺動を規制するストッパ５が曲げ加工で形成されている。なお、このストッパは、必ずしも設けなくてもよい。   The track ring 1 is a press-formed product of a steel plate, and as shown in FIGS. 1B and 2A, the axial movement of the roller 2 is restricted at both axial ends of the track surface 1a. 4 is formed by flange bending. In addition, like the conventional example shown in FIG. 5, the hooks of the race rings may be provided only on either one of both end portions in the axial direction of the raceway surface. Moreover, the stopper 5 which controls the rocking | fluctuation of the holder | retainer 3 is formed in the both ends of the circumferential direction of the track surface 1a by the bending process. Note that this stopper is not necessarily provided.

また、図２（ａ）、（ｂ）に示すように、軌道輪１の外径面１ｂには、その周方向中心部の軸方向中央位置に、軌道輪１軸方向と直交する方向に延びる矩形断面のキー溝６が設けられ、このキー溝６に対向するようにハウジング１１の凹円弧状部１１ａにも矩形断面のキー溝１３が設けられている。そして、軌道輪１のキー溝６とハウジング１１のキー溝１３とに矩形断面のキー７が係合することにより、軌道輪１がハウジング１１の凹円弧状部１１ａに位置決めされている。   Further, as shown in FIGS. 2A and 2B, the outer diameter surface 1 b of the bearing ring 1 extends in a direction perpendicular to the axial direction of the bearing ring at the axial center position of the circumferential center portion thereof. A key groove 6 having a rectangular section is provided, and a key groove 13 having a rectangular section is also provided in the concave arcuate portion 11 a of the housing 11 so as to face the key groove 6. Then, the key 7 having a rectangular cross section is engaged with the key groove 6 of the bearing ring 1 and the key groove 13 of the housing 11, whereby the bearing ring 1 is positioned on the concave arcuate portion 11 a of the housing 11.

この揺動軸受は、上記の構成であり、軌道輪１のキー溝６とハウジング１１の凹円弧状部１１ａに設けられたキー溝１３とにキー７を係合させることにより、軌道輪１をハウジング１１の凹円弧状部１１ａに位置決めしているので、軌道輪１が外径面１ｂの周方向中心部でハウジング１１の凹円弧状部１１ａと接触する場合でも、キー７とキー溝６、１３との係合によって軌道輪１の動きを拘束でき、可動部材１２の凸円弧状部１２ａを容易に組み付けることができる。   This oscillating bearing has the above-described configuration. By engaging the key 7 with the key groove 6 of the bearing ring 1 and the key groove 13 provided in the concave arcuate portion 11a of the housing 11, the bearing ring 1 is moved. Since the positioning is performed on the concave arc-shaped portion 11a of the housing 11, even when the race 1 contacts the concave arc-shaped portion 11a of the housing 11 at the circumferential center of the outer diameter surface 1b, the key 7 and the key groove 6, The movement of the race 1 can be restrained by the engagement with 13, and the convex arcuate portion 12 a of the movable member 12 can be easily assembled.

また、軌道輪１のキー溝６が軌道面１ａへ貫通しておらず、軌道面１ａに従来のような過大面圧を発生させる凹部がないため、軌道輪１の早期剥離を生じるおそれが少なく、長期間安定して使用できる。   In addition, since the keyway 6 of the bearing ring 1 does not penetrate the raceway surface 1a and there is no concave portion that generates excessive surface pressure as in the prior art, there is little risk of early separation of the raceway ring 1. Can be used stably for a long time.

図３（ａ）、（ｂ）および図４（ａ）、（ｂ）は、第２の実施形態を示す。この実施形態の軌道輪１には、外径面１ｂの周方向中心部の軸方向一端側に、軸方向に延びる半円形断面のキー溝６が設けられている。一方、ハウジング１１の凹円弧状部１１ａには、軌道輪１のキー溝６に対向する位置に、矩形断面のキー溝１３が設けられている。また、軌道輪１およびハウジング１１のキー溝６、１３と係合するキー７は、円筒形に形成されている。その他の基本的な構成および作用、すなわち、キー７とキー溝６、１３との係合により軌道輪１の動きを拘束できる点、軌道面１ａに凹部がなく軌道輪１の早期剥離を防止できる点は、第１の実施形態と同じである。   3 (a) and 3 (b) and FIGS. 4 (a) and 4 (b) show a second embodiment. The raceway ring 1 of this embodiment is provided with a keyway 6 having a semicircular cross section extending in the axial direction on one axial end side of the circumferential center portion of the outer diameter surface 1b. On the other hand, the concave arcuate portion 11 a of the housing 11 is provided with a key groove 13 having a rectangular cross section at a position facing the key groove 6 of the race 1. Further, the key 7 that engages with the raceway 1 and the key grooves 6 and 13 of the housing 11 is formed in a cylindrical shape. Other basic configurations and functions, that is, the movement of the bearing ring 1 can be restricted by the engagement between the key 7 and the key grooves 6 and 13, and there is no recess in the raceway surface 1 a, so that early separation of the bearing ring 1 can be prevented. The point is the same as in the first embodiment.

なお、軌道輪のキー溝は、上述した各実施形態のように軌道面へ貫通しないものとすることが望ましいが、軌道面へ貫通させることもできる。その場合は、各実施形態に比べて軌道輪の早期剥離防止の点では劣るが、軌道輪の製作しやすさやコストの面では有利である。   In addition, although it is desirable that the keyway of the raceway does not penetrate into the raceway surface as in the above-described embodiments, it can also penetrate into the raceway surface. In that case, it is inferior in terms of prevention of early separation of the raceway ring as compared with each embodiment, but is advantageous in terms of ease of production of the raceway ring and cost.
