Description

この発明は、複列自動調心ころ軸受の外輪の計測方法、特に、非対称外輪の計測方法に関する。   The present invention relates to a method for measuring an outer ring of a double row spherical roller bearing, and more particularly to a method for measuring an asymmetric outer ring.

特定方向のアキシアル荷重に対して耐久性を向上させた複列自動調心ころ軸受は、例えば、特開２００４−２４５２５１号公報（特許文献１）に記載されている。図１に示すように、同公報に記載されている複列自動調心ころ軸受１１は、内輪１２と、外輪１３と、内輪１２および外輪１３の間に複列に配置された球面ころ１４，１５と、球面ころ１４，１５をそれぞれ保持する保持器１６とを備える。   A double-row self-aligning roller bearing having improved durability against an axial load in a specific direction is described in, for example, Japanese Patent Application Laid-Open No. 2004-245251 (Patent Document 1). As shown in FIG. 1, a double row spherical roller bearing 11 described in the publication includes an inner ring 12, an outer ring 13, and spherical rollers 14 disposed in a double row between the inner ring 12 and the outer ring 13. 15 and a retainer 16 for holding the spherical rollers 14 and 15 respectively.

外輪１３は、左右の列で共通の球面状凹部である軌道面を有する。また、球面ころ１４，１５は、ころ長さが互いに異なり、球面ころ１５のころ長さＬ２を球面ころ１４のころ長さＬ１よりも長くしている。さらに、軸受の回転中心軸に垂直な平面と、内輪１２および外輪１３によって左右の列の球面ころ１４，１５へ伝えられる合力の作用線とがなす角（以下「接触角」という）については、軸受の右側列１１ｂの接触角θ２を軸受の左側列１１ａの接触角θ１よりも大きくしている。 The outer ring 13 has a raceway surface which is a spherical concave portion common to the left and right rows. Moreover, spherical roller 14 and 15, different roller length from each other, are longer than the roller length L 1 of the spherical rollers 14 the length L 2 days of spherical rollers 15. Further, regarding an angle (hereinafter referred to as “contact angle”) formed by a plane perpendicular to the rotation center axis of the bearing and an action line of resultant force transmitted to the left and right rows of spherical rollers 14 and 15 by the inner ring 12 and the outer ring 13, the contact angle theta 2 of the right column 11b of the bearing is larger than the contact angle theta 1 of the left column 11a of the bearing.

上記構成とすることにより、ころ長さおよび接触角を大きくした軸受の右側列１１ｂのアキシアル荷重負荷能力を高くすることができる。その結果、負荷に応じた適切な支持が各列で行えて、実質寿命を延長することができる。また、材料に無駄がなく経済的な複列自動調心ころ軸受１１が得られる。   By setting it as the said structure, the axial load load capability of the right side row | line | column 11b of the bearing which enlarged roller length and contact angle can be made high. As a result, appropriate support according to the load can be provided in each row, and the real life can be extended. Moreover, the economical double row self-aligning roller bearing 11 can be obtained with no waste of materials.

ここで、図１に示したような、複列自動調心ころ軸受の外輪軌道面の軌道径、表面粗さ、または、真円度等（以下、「寸法等」という）の計測は、左右の各列毎に行う。   Here, as shown in FIG. 1, the measurement of the raceway diameter, surface roughness, roundness, etc. (hereinafter referred to as “dimensions”) of the outer ring raceway surface of the double row spherical roller bearings For each column.

具体的な計測方法を、左右の列で外輪軌道面の最大径部から両端面までの距離（以下、「外輪軌道面幅」という）が同一の外輪（以下、「対称外輪」という）を例にとって、図２および図３を用いて説明する。   An example of a specific measurement method using an outer ring (hereinafter referred to as “symmetric outer ring”) having the same distance (hereinafter referred to as “outer ring raceway width”) from the maximum diameter portion of the outer ring raceway surface to both end faces in the left and right rows Therefore, it demonstrates using FIG. 2 and FIG.

まず、図２に示すように、外輪２１の一方側列２１ａの端面２２を下にして計測台２６に載置し、外輪外径面２４に当て板２７を当接させて固定する。そして、外輪軌道面２５の計測台２６から所定の高さｈの位置に計測器のプローブ２８を接触させて計測を行う。   First, as shown in FIG. 2, the end surface 22 of the one side row 21 a of the outer ring 21 is placed on the measurement table 26, and a contact plate 27 is brought into contact with and fixed to the outer ring outer diameter surface 24. Then, measurement is performed by bringing the probe 28 of the measuring instrument into contact with the position of the predetermined height h from the measuring table 26 on the outer ring raceway surface 25.

次に、外輪２１の他方側列２１ｂの軌道面の計測は、図３に示すように、外輪２１を反転させて、他方側列２１ｂの端面２３を下にして計測台２６に載置して行う。その他の計測方法は、図２に示した場合と同様である。   Next, as shown in FIG. 3, the raceway surface of the other side row 21b of the outer ring 21 is measured by inverting the outer ring 21 and placing it on the measuring table 26 with the end surface 23 of the other side row 21b facing down. Do. Other measurement methods are the same as those shown in FIG.

外輪２１は対称外輪であるから、左右列２１ａ，２１ｂの軌道面の寸法等の計測は、両端面２２，２３から同一距離ｈの位置で同じ条件となる。その結果、左右列２１ａ，２１ｂの計測は、外輪を反転させるだけで、計測条件を変更することなく行うことができる。
特開２００４−２４５２５１号公報（段落番号０００８等） Since the outer ring 21 is a symmetrical outer ring, the measurement of the dimensions of the raceway surfaces of the left and right rows 21a and 21b has the same conditions at the same distance h from both end surfaces 22 and 23. As a result, the measurement of the left and right rows 21a and 21b can be performed without changing the measurement conditions by simply inverting the outer ring.
JP-A-2004-245251 (paragraph number 0008, etc.)

しかし、図１に示した複列自動調心ころ軸受１１は、左右の列でころ長さＬ１，Ｌ２および接触角θ１，θ２を互いに異ならせたことにより、左右の列で外輪軌道面幅が異なる外輪（以下、「非対称外輪」という）である。 However, the double-row self-aligning roller bearing 11 shown in FIG. 1 has an outer ring in the left and right rows by making the roller lengths L 1 and L 2 and the contact angles θ 1 and θ 2 different from each other in the left and right rows. Outer rings having different raceway widths (hereinafter referred to as “asymmetric outer rings”).

そこで、図１に示すような複列自動調心ころ軸受の非対称外輪に上記の計測方法を適用した例を、図４および図５を用いて説明する。   An example in which the above measuring method is applied to an asymmetric outer ring of a double row spherical roller bearing as shown in FIG. 1 will be described with reference to FIGS.

まず、図４に示すように、非対称外輪３１の外輪軌道面幅が長い列３１ａ（以下、「長幅列」という）の計測をするときは、長幅列３１ａ側の端面３２を下にして計測台３６に載置し、外径面３４に当て板３７を当接させて、外輪３１を固定する。そして、外輪軌道面３５の計測台３６から高さｈ１の位置に計測器のプローブ３８を接触させて計測を行う。 First, as shown in FIG. 4, when measuring a row 31 a having a long outer ring raceway surface width of the asymmetric outer ring 31 (hereinafter referred to as “long width row”), the end surface 32 on the long width row 31 a side is directed downward. The outer ring 31 is fixed by placing it on the measuring table 36 and bringing the contact plate 37 into contact with the outer diameter surface 34. Then, measurement is performed by bringing the probe 38 of the measuring instrument into contact with the position of the height h 1 from the measuring table 36 on the outer ring raceway surface 35.

次に、図５に示すように、非対称外輪３１の外輪軌道面幅が短い列３１ｂ（以下、「短幅列」という）の計測をするときは、短幅列３１ｂ側の端面３３を下にして計測台３６に載置し、当て板３７を外径面３４に当接させて、外輪３１を固定して計測を行う。その他の計測手順は図４に示した長幅列３１ａの場合と同様である。   Next, as shown in FIG. 5, when measuring a row 31 b with a short outer ring raceway surface width of the asymmetric outer ring 31 (hereinafter referred to as a “short width row”), the end surface 33 on the short width row 31 b side is directed downward. Is placed on the measuring table 36, the abutting plate 37 is brought into contact with the outer diameter surface 34, and the outer ring 31 is fixed to perform measurement. Other measurement procedures are the same as those in the case of the long width row 31a shown in FIG.

ただし、外輪３１は非対称外輪であるから、各端面３２，３３から同一距離の位置での、軌道面の寸法等は異なる。   However, since the outer ring 31 is an asymmetric outer ring, the dimensions of the raceway surfaces at the same distance from the end faces 32 and 33 are different.

そこで、左右列３１ａ，３１ｂの軌道面の寸法等を同じ位置で計測するためには、各端面３２，３３からの距離が異なる位置で計測を行わなくてはならない。図４および図５に示した外輪３１の例では、ｈ１＞ｈ２とする必要がある。 Therefore, in order to measure the dimensions of the track surfaces of the left and right rows 31a and 31b at the same position, the measurement must be performed at positions where the distances from the end faces 32 and 33 are different. In the example of the outer ring 31 shown in FIGS. 4 and 5, it is necessary to satisfy h 1 > h 2 .

したがって、非対称外輪の計測は、左右列で計測条件を変えて行わなければならず、計測作業が煩雑となる問題がある。   Therefore, the measurement of the asymmetric outer ring must be performed by changing the measurement conditions in the left and right rows, and there is a problem that the measurement work becomes complicated.

本発明の目的は、非対称外輪を有する複列自動調心ころ軸受において、外輪軌道面の計測作業を効率化する方法を提供することである。   An object of the present invention is to provide a method for improving the efficiency of measuring the outer ring raceway surface in a double row spherical roller bearing having an asymmetric outer ring.

本発明の他の目的は、非対称外輪軌道面の計測に適したブロックゲージを提供することである。   Another object of the present invention is to provide a block gauge suitable for measuring an asymmetric outer ring raceway surface.

この発明に係る非対称外輪軌道面の計測方法は、左右の列の外輪軌道面幅が互いに異なる複列自動調心ころ軸受の外輪の、長幅列の軌道面と、短幅列の軌道面とを計測する方法である。長幅列の軌道面を計測するときは、外輪の長幅列側の端面を下にして計測台上に直接載置し、計測台から所定の高さの位置にある軌道面上に計測プローブを当て、短幅列の軌道面を計測するときは、長幅列の外輪軌道面幅と、短幅列の外輪軌道面幅との差と同一の厚みを有するブロックゲージを計測台上に載置し、外輪の短幅列側の端面を下にしてブロックゲージ上に載置し、計測台から長幅列の計測時と同一の高さの位置にある軌道面上に計測プローブを当てることを特徴とする。   The method for measuring an asymmetric outer ring raceway surface according to the present invention includes: It is a method to measure. When measuring the long-width track surface, place the outer ring directly on the measurement table with the end surface on the long-width row side of the outer ring facing down, and place the measurement probe on the track surface at a predetermined height from the measurement table. When measuring the raceway surface of the short width row, a block gauge having the same thickness as the difference between the outer raceway surface width of the long width row and the outer ring raceway width of the short width row is placed on the measurement table. Place the outer ring on the block gauge with the end face on the short-width row side of the outer ring facing down, and place the measurement probe on the track surface at the same height as when measuring the long-width row. It is characterized by.

上記方法により、軸受の左右の列で、計測台から所定距離の位置での外輪軌道面の公称軌道径が同じ値となるので、外輪を反転させるのみで、計測条件を変更することなく計測を行うことができる。その結果、計測作業を効率化することができる。   By the above method, the nominal track diameter of the outer ring raceway surface at a predetermined distance from the measuring table is the same value in the left and right rows of bearings, so measurement can be performed without changing the measurement conditions by simply inverting the outer ring. It can be carried out. As a result, the measurement work can be made efficient.

この発明に係る非対称外輪軌道面の計測用ブロックゲージは、左右の列の外輪軌道面幅が互いに異なる複列自動調心ころ軸受の外輪の、長幅列の軌道面と、短幅列の軌道面とを計測する際に使用するブロックゲージであって、長幅列の外輪軌道面幅と、短幅列の外輪軌道面幅との差と同一の厚みを有することを特徴とする。   The block gauge for measuring the asymmetric outer ring raceway surface according to the present invention includes a long row raceway surface and a short width raceway of the outer ring of the double row self-aligning roller bearing in which the outer ring raceway widths of the left and right rows are different from each other. It is a block gauge used when measuring a surface, and has the same thickness as the difference between the outer ring raceway surface width of the long width row and the outer ring raceway width of the short width row.

非対称外輪の軌道面の計測を、外輪を反転させて所定のブロックゲージ上に載置するのみで、計測条件を変更することなく行うことができるので、計測作業を効率化することができる。   Since the measurement of the raceway surface of the asymmetric outer ring can be performed without changing the measurement conditions simply by inverting the outer ring and placing it on a predetermined block gauge, the measurement work can be made more efficient.

図６，７，８を参照して、この発明の一実施形態に係る非対称外輪軌道面の計測方法を説明する。   A method for measuring an asymmetric outer ring raceway surface according to an embodiment of the present invention will be described with reference to FIGS.

まず、非対称外輪４１の長幅列４１ａ側の外輪軌道面４５の計測を行うときは、図６に示すように、端面４２を下にして非対称外輪４１を計測台４６に直接載置し、外径面４４に当て板４７を当接させて固定する。そして、外輪軌道面４５の計測台４６から所定の高さｈの位置に計測器のプローブ４８を接触させて行う。   First, when measuring the outer ring raceway surface 45 on the long width row 41a side of the asymmetric outer ring 41, as shown in FIG. The contact plate 47 is brought into contact with the radial surface 44 and fixed. Then, the probe 48 of the measuring instrument is brought into contact with the position of the predetermined height h from the measuring table 46 on the outer ring raceway surface 45.

次に、非対称外輪４１の短幅列４１ｂ側の外輪軌道面４５の計測を行うときは、図７に示すように、計測台４６上にブロックゲージ４９を載置し、ブロックゲージ４９の上に、端面４３を下にして非対称外輪４１を載置し、外径面４４に当て板４７を当接させて固定する。ここで、ブロックゲージ４９厚みｔ３は、長幅列４１ａの外輪軌道面幅をｔ１とし、短幅列４１ｂの外輪軌道面幅をｔ２とすると、ｔ３＝ｔ１−ｔ２となるように設定する。 Next, when measuring the outer ring raceway surface 45 on the short width row 41 b side of the asymmetric outer ring 41, as shown in FIG. 7, a block gauge 49 is placed on the measurement table 46, and the block gauge 49 is placed on the block gauge 49. The asymmetric outer ring 41 is placed with the end face 43 facing down, and a contact plate 47 is brought into contact with the outer diameter surface 44 and fixed. Here, the block gauge 49 thickness t 3, the outer ring raceway surface width of the long width columns 41a and t 1, when the outer ring raceway surface of the Short width columns 41b and t 2, a t 3 = t 1 -t 2 Set as follows.

こうすることで、長幅列４１ａの外輪軌道面幅ｔ１と、短幅列４１ｂの外輪軌道面幅ｔ２にブロックゲージ４９の幅ｔ３を加えた幅とが同一となるので、外輪４１を対称外輪として取り扱うことが可能となる。 In this way, the outer ring raceway surface width t 1 of the long width column 41a, the width plus the width t 3 of the outer ring raceway surface width t 2 in gauge blocks 49 of a short width columns 41b and are the same, the outer ring 41 Can be handled as a symmetrical outer ring.

上記構成とすることにより、計測台４６から距離ｈの位置での短幅列４１ｂの軌道面４５の公称軌道径は、計測台４６から距離ｈの位置での長幅列４１ａの軌道面４５の公称軌道径と同じ値となる。   With the above configuration, the nominal orbital diameter of the track surface 45 of the short width row 41b at the position h from the measurement table 46 is the same as that of the track surface 45 of the long width row 41a at the position h from the measurement table 46. The same value as the nominal track diameter.

その結果、図８に示すように、短幅列４１ｂについても、長幅列４１ａの場合と同様に、計測台４６からｈの位置で軌道面４５の計測を行うことができる。   As a result, as shown in FIG. 8, the track surface 45 can also be measured at the position h from the measurement table 46 in the short width row 41b as in the case of the long width row 41a.

上記方法を用いることにより、非対称外輪軌道面の左右列の計測についても、非対称外輪４１を反転させてブロックゲージ４９上に載置するだけで、計測条件を変更することなく行うことができるので、外輪軌道面の計測作業を効率化することができる。   By using the above method, the measurement of the left and right rows of the asymmetric outer ring raceway surface can be performed without changing the measurement conditions simply by inverting the asymmetric outer ring 41 and placing it on the block gauge 49. Measurement work of the outer ring raceway surface can be made efficient.

上記の実施形態では、長幅列４１ａ側の計測を先に行い、短幅列４１ｂ側の計測を後で行ったが、これに限ることなく、短幅列４１ｂ側の計測を先に行ってもよい。   In the above embodiment, the measurement on the long width column 41a side is performed first, and the measurement on the short width column 41b side is performed later. However, the measurement is not limited to this, and the measurement on the short width column 41b side is performed first. Also good.

以上、図面を参照してこの発明の実施形態を説明したが、この発明は、図示した実施形態のものに限定されない。図示した実施形態に対して、この発明と同一の範囲内において、あるいは均等の範囲内において、種々の修正や変形を加えることが可能である。   As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to the thing of embodiment shown in figure. Various modifications and variations can be made to the illustrated embodiment within the same range or equivalent range as the present invention.

この発明は、非対称外輪を有する複列自動調心ころ軸受において、外輪軌道面の計測に有利に利用される。   The present invention is advantageously used for measuring the outer ring raceway surface in a double row spherical roller bearing having an asymmetric outer ring.
