Description
本発明は、軸受を軸方向に固定する2分割止め輪に関する。 The present invention relates to a two-part retaining ring for fixing a bearing in an axial direction.
軸受を軸に装着する場合、軸方向への移動を防止する為に、例えば特許文献1の技術のように、2分割された止め輪が使用される場合がある。 When the bearing is mounted on the shaft, in order to prevent movement in the axial direction, a retaining ring divided into two may be used as in the technique of Patent Document 1, for example.
この2分割止め輪7は、図4に示すように、一対の半円状の止め輪分割体9、9からなる。これら止め輪分割体9は互いに同じ形状のものである。各止め輪分割体9は、軸受内輪(図3を参照)の幅面に係合可能な径方向高さである板幅6bを有し、板厚t(図5(B))比べて板幅6bが十分に広い板状に形成されている。すなわち、止め輪分割体9の内径d(図5(A))は、軸6の内径d1(図4)よりも小さく、軸の止め輪溝(図示せず)の内径と略一致させてある。
As shown in FIG. 4, the two-part
各止め輪分割体9は、両端に互いに係脱可能な結合部10A、10Bを有している。一端の結合部10Aは、通常幅部分9aの端部の外径部から幅狭となって円周方向に延びる首部11A、およびこの首部11Aの先端から内径側へ突出して先端面が内径側に向くテーパ面となった三角形状の外径側爪12Aからなる。他端の結合部10Bは、通常幅部分9aの端部の内径部から幅狭となって円周方向に延びる首部11B、およびこの首部11Bの先端から外径側へ突出して先端面が外径側に向くテーパ面となった三角形状の内径側爪12Bからなる。外径側爪12Aおよび内径側爪12Bの背面である引っ掛かり面12a、12bは、図5のように止め輪分割体9の半径方向に対して先端が首部側11A、11B側へ傾く傾斜角θを持たせてある。
Each
これら一対の止め輪分割体9、9は、軸の止め輪溝への装着に際して、図4のように2個を180°位相をずらせて軸の両側から対向配置し、矢印Fのように互いに対向方向に押し込むことで結合させる。この押し込みに際して、対向する爪12A、12Bの先端面間の接触により、外径側爪12Aが外側に、また組み込み初期のみ内径側爪12Bが内側に逃げるように、各首部11A、11Bが撓む。このような撓みが可能なように、各首部11A、11Bの断面高さを小さく設定してある。外径側爪12Aと内径側爪12Bが噛み合ったときに、図5のように装着が完了する。このように両止め輪分割体9、9を結合した状態で、爪12Aの先端面とこの面に対面する止め輪分割体9の通常幅部分9aの端面との間に隙間Cが生じるように、通常幅部分9aの端面9bを形成してある。また爪12Bの外径側にも隙間Dが生じる。
The pair of
このような2分割止め輪は、止め輪を2分割に形成することで、組み込み時の径方向高さの制限が無くなり、止め輪の径方向高さを自由に設計できる。そのため、このような止め輪を軸受のシール摺接部付近に配置すると、いわゆるスリンガー的な効果も期待できるが(図3を参照)、従来技術の2分割留め輪では、その結合部付近に隙間C、D(図5)があり、この隙間から水等の異物が直接軸受のシール部に掛かり、軸受内部に異物が浸入しやすいという問題があり、十分なスルンガー効果を期待することは困難であった。 In such a two-part retaining ring, by forming the retaining ring into two parts, there is no restriction on the radial height when assembled, and the radial height of the retaining ring can be freely designed. Therefore, if such a retaining ring is arranged in the vicinity of the seal sliding contact portion of the bearing, a so-called slinger effect can be expected (see FIG. 3). However, in the conventional two-part retaining ring, there is a gap near the coupling portion. There are C and D (Fig. 5), and there is a problem that foreign matters such as water are directly applied to the seal portion of the bearing from this gap, and foreign matters are likely to enter the bearing, and it is difficult to expect a sufficient Srunger effect. there were.
本発明の2分割止め輪は、上述の様な事情に鑑み、従来の2分割止め輪と同等の軸方向固定機能を有しながら、軸受内部に水や異物が浸入することの防止性能の向上を図るべく発明したものである。 In view of the circumstances as described above, the two-part retaining ring of the present invention has an axial direction fixing function equivalent to that of the conventional two-part retaining ring, while improving the performance of preventing water and foreign matter from entering the bearing. It was invented to achieve this.
本発明の上記目的は、下記の構成により達成される。
一対の半円状の止め輪分割体からなり、各止め輪分割体の両端に互いに係脱可能な結合部を設けた2分割止め輪において、前記各止め輪分割体の外径は、軸受内輪のシール摺動部分よりも大きく、前記結合部に隙間がない構成の2分割止め輪。
The above object of the present invention can be achieved by the following constitution.
A two-part retaining ring comprising a pair of semi-circular retaining ring segments and provided with coupling portions that can be engaged with and disengaged from each other at both ends of each retaining ring segment. A two-part retaining ring configured to be larger than the seal sliding portion and having no gap in the joint portion.
上述の様に構成する本発明の軸受固定用の2分割止め輪によれば、従来の2分割止め輪と同等の軸方向位置決め機能を有しながら、従来の隙間(C、D)部分を弾性体で塞いでいるため従来の2分割止め輪に比べ異物浸入や防止性能が向上している。また軸受シール部材の摺動面を充分覆う径方向幅とすることにより、軸受のシール部材との間にラビリンス隙間を設けられ、さらに効果を得ることができる。 According to the two-part retaining ring for fixing a bearing of the present invention configured as described above, the conventional gap (C, D) portion is elastic while having the same axial positioning function as the conventional two-part retaining ring. Since it is closed by the body, the invasion of foreign matter and the prevention performance are improved as compared with the conventional two-part retaining ring. Further, by setting the radial width to sufficiently cover the sliding surface of the bearing seal member, a labyrinth gap is provided between the bearing seal member and the bearing seal member, and further effects can be obtained.
図1、図2及び図3を参照して、本発明に係る実施形態である2分割止め輪について説明する。尚、本実施形態の特徴は、2分割止め輪の結合部付近の隙間を塞ぐ構造を工夫した点にある。その他の部分の基本構造及び作用は、図4、図5に示した従来構造の2分割止め輪と同様であるから、同等部分には同一符号を付して、重複する説明を省略若しくは簡略にし、以下、本実施形態の特徴部分、並びに、上述した従来構造と異なる部分を中心に説明する。 With reference to FIG.1, FIG2 and FIG.3, the 2 split retaining ring which is embodiment which concerns on this invention is demonstrated. The feature of this embodiment is that the structure for closing the gap in the vicinity of the coupling portion of the two-part retaining ring is devised. Since the basic structure and operation of the other parts are the same as those of the conventional two-part retaining ring shown in FIGS. 4 and 5, the same parts are denoted by the same reference numerals, and redundant explanations are omitted or simplified. Hereinafter, the characteristic part of this embodiment and the part different from the conventional structure described above will be mainly described.
この2分割止め輪17は、図1に示すように、一対の半円状の止め輪分割体19、19からなる。これら止め輪分割体19は互いに同じ形状のものである。
As shown in FIG. 1, the two-
各止め輪分割体19は、首部11Aの内径側、および首部11Bの外径側にゴム等の弾性部材20、20を接着している。これらの弾性部材の形状は、図2のように各止め輪分割体19、19を結合したときに、従来2分割止め輪(図5)の隙間C、Dを塞ぐような形状としている。なお、本発明の実施形態である2分割止め輪は、前記の弾性部材20、20以外は、従来2分割止め輪(図5)と同形状である。
Each retaining
図3のように、軸受18のシール部材22の摺動部側の止め輪、即ち、シール部材22が外輪固定、内輪摺動の場合の軸用の2分割止め輪17の外径をシール部材22の摺動部22aを覆う程度まで大きくすることで、シール摺動部22aへ直接、水や異物が届かなくなり、より高い異物浸入防止性能を発揮できる。更に2分割止め輪17とシール部材22との間にラビリンス隙間を設けることにより、更に異物の浸入防止性能を向上することができる。なお、図3の21は、通常のC型止め輪である。
As shown in FIG. 3, the retaining ring on the sliding portion side of the
上述の様に構成する本発明の軸受固定用の2分割止め輪によれば、従来の2分割止め輪と同等の軸方向位置決め機能を有しながら、従来の隙間(C、D)部分を弾性体で塞いでいるため従来の2分割止め輪に比べ異物浸入や防止性能が向上している。また軸受シール部材の摺動面を充分覆う径方向幅とすることにより、軸受のシール部材との間にラビリンス隙間を設けられ、さらに効果を得ることができる。 According to the two-part retaining ring for fixing a bearing of the present invention configured as described above, the conventional gap (C, D) portion is elastic while having the same axial positioning function as the conventional two-part retaining ring. Since it is closed by the body, the invasion of foreign matter and the prevention performance are improved as compared with the conventional two-part retaining ring. Further, by setting the radial width to sufficiently cover the sliding surface of the bearing seal member, a labyrinth gap is provided between the bearing seal member and the bearing seal member, and further effects can be obtained.
