Description

本発明は、ベアリングの構造に関し、詳しくはローリングベアリングに関するものである。   The present invention relates to a bearing structure, and more particularly to a rolling bearing.

従来、ベアリング（bearing）は機械中でよく見掛けられる回転ユニットであり、回転ユニットをスムーズに回転させ、軸を適切に支持することができる。一般的にローリングベアリングは、ローリングユニット（ボールまたは円柱型ローラー）をベアリング内に装着するため、ベアリングの内側円形環状体または外側円形環状体を二つに分割し、二つの内側円形環状シェルまたは二つの外側円形環状シェルを形成する必要がある。ベアリングを組み立てる際、内側円形環状体および一つの外側円形環状シェル（または外側円形環状体および一つ内側円形環状シェル）を組み合わせ、そののちローリングユニットをローリング溝に装着し、続いて別の一つの外側円形環状シェル（または内側円形環状シェル）と前述した外側円形環状シェルとを結合させ、ローリングユニットの装着口を密封する。続いて二つの外側円形環状シェル（または内側円形環状シェル）を締め付けるために二つの外側円形環状シェル（または内側円形環状シェル）に形成された結合孔にボルトを差し込み、二つの外側円形環状シェル（または内側円形環状シェル）を締め付ける。例えば、特許文献１、特許文献２、特許文献３に開示された二つの外側円形環状シェルの締め付け方法は、一端から他端にボルトを締め付けることによって組み合わせることである。   Conventionally, a bearing is a rotating unit often found in machines, and can rotate the rotating unit smoothly and support the shaft appropriately. Generally, in order to mount a rolling unit (ball or cylindrical roller) in the bearing, the rolling bearing is divided into two inner circular annular bodies or two inner circular annular shells or two parts. Two outer circular annular shells need to be formed. When assembling the bearing, combine the inner circular annulus and one outer circular annular shell (or the outer circular annulus and one inner circular annular shell), then install the rolling unit in the rolling groove and then another one The outer circular annular shell (or inner circular annular shell) and the outer circular annular shell described above are coupled to seal the mounting opening of the rolling unit. Subsequently, in order to tighten the two outer circular annular shells (or the inner circular annular shell), a bolt is inserted into a coupling hole formed in the two outer circular annular shells (or the inner circular annular shell), and the two outer circular annular shells ( Or tighten the inner circular annular shell). For example, the fastening method of the two outer circular annular shells disclosed in Patent Literature 1, Patent Literature 2, and Patent Literature 3 is to combine them by fastening bolts from one end to the other end.

しかしながら、このような組み合わせ方式は、ボルトを一端から他端に締め付けて組み合わせることであるため、二つの外側円形環状シェル（または内側円形環状シェル）のうちの一つはボルトヘッド部を完全に収容するための陥没孔を有し、別の一つの外側円形環状シェルはボルトヘッド部を収容する必要がないため、ねじ孔のみを有する。しかしながら、陥没孔とねじ孔の配置方法は二つの外側円形環状シェル（または内側円形環状シェル）の間の互換性がないという事態を生じるため、部品および材料の在庫を増加させてしまうだけでなく、特に日増しに厳しくなる経営環境下で経済の負担およびリスクを増大させる。一方、陥没孔の直径がねじ孔の直径より大きいことに対し、あらゆる陥没孔の配置に用いられる外側円形環状シェル（または内側円形環状シェル）は除去される部位が比較的多いため、構造強度が比較的低い。特に外力または熱処理を受けて組織を変化させると、構造が変形しやすくなるだけでなく、ベアリングの製造品質に影響を与えてしまう。一方、二つの外側円形環状シェル（または内側円形環状シェル）の結合孔は形が異なるだけでなく、構造および質量などの物理特性も異なるため、精密機構には二つの外側円形環状シェル（または内側円形環状シェル）の構造および質量が相互に対応しないという問題がある。   However, since such a combination method is to combine the bolts from one end to the other end, one of the two outer circular annular shells (or the inner circular annular shell) completely accommodates the bolt head part. And the other outer circular annular shell does not need to accommodate the bolt head portion, and therefore has only a screw hole. However, the placement method of the recessed hole and the screw hole not only increases the stock of parts and materials, but also causes an incompatibility between the two outer circular annular shells (or the inner circular annular shell). Increase the economic burden and risk, especially in a business environment that is becoming increasingly severe. On the other hand, since the diameter of the recessed hole is larger than the diameter of the screw hole, the outer circular annular shell (or inner circular annular shell) used for the arrangement of all the recessed holes has a relatively large number of parts to be removed. Relatively low. In particular, when the structure is changed by receiving external force or heat treatment, the structure is not only easily deformed, but also affects the manufacturing quality of the bearing. On the other hand, the coupling holes of the two outer circular annular shells (or inner circular annular shells) not only differ in shape but also in physical properties such as structure and mass, so the precision mechanism has two outer circular annular shells (or inner There is a problem that the structure and mass of the circular annular shell) do not correspond to each other.

本発明は、部品種類を低減可能なローリングベアリングを提供することを目的とする。   An object of this invention is to provide the rolling bearing which can reduce a component kind.

上述の目的を達成するために、本発明によるローリングベアリングは、円形環状体、第１円形環状シェル、第２円形環状シェル、複数のローリングユニットおよび複数の締付ユニットを備える。円形環状体は第一ローリング溝を有する。第１円形環状シェルおよび第２円形環状シェルは、同じ構成を有し、第一側面、第二側面と、第一側面に形成された斜面と、第二側面に配置された複数の陥没孔および複数のねじ孔とを有する。第１円形環状シェルの第一側面と第２円形環状シェルの第一側面とは相互に接触し、第１円形環状シェルの斜面と第２円形環状シェルの斜面は、第一ローリング溝と対向する第二ローリング溝を形成する。第二ローリング溝と第一ローリング溝とは、ローリング空間を形成する。第１円形環状シェルおよび第２円形環状シェルのうち、一方の陥没孔と他方のねじ孔とは相互に連通する。複数のローリングユニットはローリング空間に配置される。複数の締付ユニットは陥没孔およびねじ孔に差し込まれ、円形環状シェルを締め付ける。   To achieve the above object, a rolling bearing according to the present invention includes a circular annular body, a first circular annular shell, a second circular annular shell, a plurality of rolling units, and a plurality of clamping units. The circular annular body has a first rolling groove. The first circular annular shell and the second circular annular shell have the same configuration, and include a first side surface, a second side surface, a slope formed on the first side surface, a plurality of recessed holes disposed on the second side surface, and A plurality of screw holes. The first side surface of the first circular annular shell and the first side surface of the second circular annular shell are in contact with each other, and the slope surface of the first circular annular shell and the slope surface of the second circular annular shell face the first rolling groove. A second rolling groove is formed. The second rolling groove and the first rolling groove form a rolling space. Of the first circular annular shell and the second circular annular shell, one recessed hole and the other screw hole communicate with each other. The plurality of rolling units are arranged in the rolling space. A plurality of tightening units are inserted into the recessed holes and screw holes to tighten the circular annular shell.

上述した構造により、二つの同じ円形環状シェルである第１円形環状シェルおよび第２円形環状シェルを使用することで、部品種類を低減することができ、異なる円形環状シェルを使用してベアリングを組み立てる従来の技術に比べて、本発明は部品および材料の在庫を減らすことができる。また本発明は第１円形環状シェルおよび第２円形環状シェルの構造を一致させることによって変形上の差異がベアリングの製造品質に影響を与えることを避けることができるだけでなく、第１円形環状シェルおよび第２円形環状シェルの構造および質量が一致するため、精密機構には二つの円形環状シェルの構造および質量が相互に対応しないという問題を解決することができる。   With the structure described above, the use of two identical circular annular shells, the first circular annular shell and the second circular annular shell, can reduce part types and assemble bearings using different circular annular shells. Compared to the prior art, the present invention can reduce the inventory of parts and materials. The present invention not only avoids that the difference in deformation affects the manufacturing quality of the bearing by matching the structure of the first circular annular shell and the second circular annular shell, Since the structure and mass of the second circular annular shell coincide, the problem that the structures and masses of the two circular annular shells do not correspond to each other in the precision mechanism can be solved.

On the other hand, the number of the recessed holes 124 and the screw holes 125 may not be the same, but the excessive recessed holes 124 or screw holes 125 adversely affect the strength of the first circular annular shell 12 and the second circular annular shell 12. Reach.

本実施形態において、陥没孔１２４とねじ孔１２５とは第１円形環状シェル１２（第２円形環状シェル１２）に交互に分布する。交互分布とは同じ第１円形環状シェル１２（または第２円形環状シェル１２）に位置する陥没孔１２４とねじ孔１２５とを陥没孔―ねじ孔―陥没孔―ねじ孔の順に配列することである。   In the present embodiment, the recessed holes 124 and the screw holes 125 are alternately distributed in the first circular annular shell 12 (second circular annular shell 12). The alternating distribution means that the recessed holes 124 and the screw holes 125 located in the same first circular annular shell 12 (or the second circular annular shell 12) are arranged in the order of recessed holes-screw holes-depressed holes-screw holes. .

本実施形態において、陥没孔１２４とねじ孔１２５とは相互に一定距離を置いて第１円形環状シェル１２（または第２円形環状シェル１２）に交互に分布する。一定距離とは陥没孔１２４とねじ孔１２５との節の直径が一致し、陥没孔１２４とねじ孔１２５との間に置いた距離が一致することである。   In the present embodiment, the recessed holes 124 and the screw holes 125 are alternately distributed in the first circular annular shell 12 (or the second circular annular shell 12) at a certain distance from each other. The constant distance means that the diameters of the nodes of the depression hole 124 and the screw hole 125 are equal, and the distance placed between the depression hole 124 and the screw hole 125 is coincident.

以下、第１実施形態の組立方法について説明を進める。まず円形環状体１１を用意し、円形環状体１１に第１円形環状シェル１２を嵌め込み、そののちローリングユニット１３を中に装着する。続いて第２円形環状シェル１２を円形環状体１１に嵌め込み、陥没孔１２４とねじ孔１２５とを繋げる。続いて陥没孔１２４とねじ孔１２５に締付ユニット１４を差し込み、第１円形環状シェル１２と第２円形環状シェル１２とを締め付ける。   Hereinafter, description will be given of the assembly method of the first embodiment. First, the circular annular body 11 is prepared, the first circular annular shell 12 is fitted into the circular annular body 11, and then the rolling unit 13 is mounted therein. Subsequently, the second circular annular shell 12 is fitted into the circular annular body 11 to connect the recessed hole 124 and the screw hole 125. Subsequently, the tightening unit 14 is inserted into the recessed hole 124 and the screw hole 125, and the first circular annular shell 12 and the second circular annular shell 12 are tightened.

陥没孔１２４とねじ孔１２５とは相互に一定距離を置いて第１円形環状シェル１２（第２円形環状シェル１２）に交互に分布され、陥没孔１２４の数とねじ孔１２５の数の合計がＮである場合、第１円形環状シェル１２（第２円形環状シェル１２）を裏返し、３６０／Ｎ度回転させれば陥没孔１２４をねじ孔１２５に対応させることができる。   The recessed holes 124 and the screw holes 125 are alternately distributed in the first circular annular shell 12 (second circular annular shell 12) at a certain distance from each other, and the total number of the recessed holes 124 and the screw holes 125 is determined. In the case of N, if the first circular annular shell 12 (second circular annular shell 12) is turned upside down and rotated 360 / N degrees, the recessed hole 124 can correspond to the screw hole 125.

（第２実施形態）
図４に示したのは第２実施形態である。第１実施形態との違いは次の通りである。外側円形環状体を二つの第１円形環状シェル１２および第２円形環状シェル１２に分割する第１実施形態に対し、第２実施形態は内側円形環状体を二つの第１円形環状シェル１６および第２円形環状シェル１６に分割する。 (Second Embodiment)
FIG. 4 shows the second embodiment. Differences from the first embodiment are as follows. In contrast to the first embodiment in which the outer circular annular body is divided into two first circular annular shells 12 and a second circular annular shell 12, the second embodiment divides the inner circular annular body into two first circular annular shells 16 and Divide into two circular annular shells 16.

図５に示したのは第３実施形態である。第１実施形態との違いは次の通りである。陥没孔１２４とねじ孔１２５とは相互に対応するように第１円形環状シェル１２および第２円形環状シェル１２に分布される。かつ陥没孔１２４は集中されるため、締付ユニット１４による締め付けが簡単になる。このとき陥没孔１２４の数とねじ孔１２５の数の合計がＮである場合、陥没孔１２４をねじ孔１２５に対応させるには、第１円形環状シェル１２（第２円形環状シェル１２）を裏返し、１８０度回転させればよい。 (Third embodiment)
FIG. 5 shows the third embodiment. Differences from the first embodiment are as follows. The recessed hole 124 and the screw hole 125 are distributed in the first circular annular shell 12 and the second circular annular shell 12 so as to correspond to each other. In addition, since the recessed holes 124 are concentrated, tightening by the tightening unit 14 is simplified. At this time, when the sum of the number of the recessed holes 124 and the number of the screw holes 125 is N, the first circular annular shell 12 (second circular annular shell 12) is turned over to make the recessed holes 124 correspond to the screw holes 125. , 180 degrees may be rotated.

第１円形環状シェル１２（第２円形環状シェル１２）の受けた力を平均させる場合、陥没孔１２４とねじ孔１２５とは相互に対応するように一定距離を置いて第１円形環状シェル１２（第２円形環状シェル１２）に分布することが好ましい、即ち第１実施形態および第２実施形態を採用することが好ましい。   When the force received by the first circular annular shell 12 (second circular annular shell 12) is averaged, the first circular annular shell 12 (with a fixed distance is provided so that the recessed hole 124 and the screw hole 125 correspond to each other. The second circular annular shell 12) is preferably distributed, that is, it is preferable to employ the first and second embodiments.
