(57) [Summary] [Purpose] The purpose is to increase the alignment angle of spherical plain bearings. [Structure] In the structure shown in FIG. 1, this spherical sliding bearing has the wall thickness t and width w of the outer ring 2 set in accordance with the required alignment angle θ. That is, the alignment angle θ is limited by the interference between the shaft 3 and the housing 4, and the more the interference part 4a between the housing 4 and the shaft 3 moves away from each other in the outer radial direction or approaches the center in the axial direction, the more the alignment becomes The angle θ becomes larger. In other words, the alignment angle θ can be determined by the set position of the interference portion 4a, and furthermore, the set position of the interference portion can be determined by the wall thickness t and width w of the outer ring 2. Therefore, by increasing the wall thickness t of the outer ring 2, the interference portion 4a can be positioned further in the outer diameter direction, and by further decreasing the width w, it can be positioned closer to the center in the axial direction. θ can be easily increased.

本考案は、球面すべり軸受に関し、特に大きな調心角を可能にしたものに関す る。 This invention relates to spherical plain bearings, especially those that enable a large alignment angle. Ru.
【０００２】0002
球面すべり軸受は内輪が外輪の内径面を揺動することにより、内輪に挿通され た軸の撓み等を吸収（調心）する作用をなすものであるが、従来の球面すべり軸 受の調心角は一般に５〜１５゜であった。これは、図２に示すように、内輪１が 所定角（θ）揺動すると、軸３と外輪２を固定するハウジング４とが干渉し、内 輪１の揺動が阻止されるためである。 Spherical plain bearings are inserted into the inner ring by swinging the inner ring on the inner surface of the outer ring. This has the effect of absorbing (aligning) the deflection, etc. of the shaft, but compared to the conventional spherical sliding shaft. The alignment angle of the bridge was generally 5 to 15 degrees. This means that the inner ring 1 is When swinging by a predetermined angle (θ), the shaft 3 and the housing 4 that fixes the outer ring 2 interfere, and the inner This is because the swinging of the wheel 1 is prevented.

例えば、免震装置に使用される鋼棒ダンパ−においては、地震の想定レベルが 大きくなるにしたがって、鋼棒を支持する球面すべり軸受にも大きな調心角が要 求されるようになってきた。しかしながら、従来の球面すべり軸受は最大調心角 が１５゜以下と小さいため、このような大きな調心角が要求される用途への使用 が制限されていた。 For example, for steel bar dampers used in seismic isolation devices, the expected earthquake level is As the steel rod becomes larger, the spherical plain bearing that supports the steel rod also requires a larger alignment angle. It's starting to be sought after. However, conventional spherical plain bearings have a maximum alignment angle of Since the angle is as small as 15° or less, it can be used in applications that require such a large centering angle. was restricted.
【０００４】 調心角を増大させる手段として、内輪内径部のクラウニング量を大きく取るこ とが考えられるが、調心角が制限されるのは軸とハウジングとの干渉による要因 が大であるから、この手段では調心角をあまり大きくすることができない。また 、クラウニング加工のために生産性の点で問題がある。0004 One way to increase the alignment angle is to increase the amount of crowning on the inner diameter of the inner ring. However, the alignment angle is limited due to interference between the shaft and the housing. is large, so this means cannot increase the alignment angle very much. Also , there is a problem in terms of productivity due to the crowning process.
【０００５】 そこで、本考案の目的は、球面すべり軸受の調心角を、生産性を低下させると なく増大させることにある。[0005] Therefore, the purpose of this invention is to reduce the alignment angle of spherical plain bearings in order to reduce productivity. The goal is to increase the number of people without having to worry about it.

【課題を解決するための手段】 本考案は、内径面が凹状の球面をなす外輪、外径面が凸状の球面をなし、外輪 の内径面に摺動自在に挿入される内輪で構成されるものにおいて、外輪の肉厚お よび幅寸法が、軸線を基準とする内輪の揺動角（調心角）に対応して設定された ことを特徴とする球面すべり軸受を提供する。[Means to solve the problem] This invention has an outer ring with a concave spherical inner diameter surface, a convex spherical outer ring with an outer diameter surface, and an outer ring with a concave spherical inner diameter surface. consists of an inner ring that is slidably inserted into the inner diameter surface of the and width dimensions are set corresponding to the swing angle (alignment angle) of the inner ring with respect to the axis. To provide a spherical plain bearing characterized by the following.
【０００７】[0007]
ハウジングと軸との干渉部位が外径方向に離れる程、また軸方向中心に近付く 程調心角は大きくなる。本考案は、外輪の肉厚および幅寸法をこの観点から設定 することにより、調心角の増大を可能にせんとするものである。 The farther apart the interference part between the housing and the shaft is in the radial direction, the closer it gets to the center in the axial direction. The centering angle becomes larger. This invention sets the wall thickness and width dimensions of the outer ring from this perspective. By doing so, it is possible to increase the centering angle.

以下、本考案の実施例を図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described based on the drawings.
【０００９】 図１に示すように、本考案の球面すべり軸受は、内径面２ａが凹状の球面をな す外輪２、外径面１ａが凸状の球面をなし、外輪２の内径面２ａに揺動自在に挿 入される内輪１で構成される。内輪１の内径部のエッジ部にはカットクラウニン グ１ｂが形成されており、この内径部に軸３が挿通される。そして、軸３が荷重 をうけて撓んだ場合等には、軸３の撓み方向に内輪１が揺動してこの撓みを吸収 する。外輪２は周方向に２分割された形状をなし、外径側をハウジング４に嵌合 固定されている。尚、５は２分割された外輪２を相互に固定するためのボルトで ある。このボルト５は主に組立の際の便宜を考慮したものであり、外輪２はハウ ジング４で固定されるから、ボルト５は必ずしも必要なものではない。[0009] As shown in Fig. 1, the spherical plain bearing of the present invention has an inner diameter surface 2a having a concave spherical surface. An outer ring 2, the outer diameter surface 1a of which has a convex spherical surface, is swingably inserted into the inner diameter surface 2a of the outer ring 2. It consists of an inner ring 1 that is inserted. Cut crowning is applied to the edge of the inner diameter of inner ring 1. A shaft 3 is inserted into the inner diameter portion of the shaft 1b. Then, shaft 3 is loaded When the inner ring 1 is deflected due to the bending, the inner ring 1 swings in the direction of the deflection of the shaft 3 to absorb this deflection. do. The outer ring 2 has a shape divided into two in the circumferential direction, and the outer diameter side is fitted into the housing 4. Fixed. In addition, 5 is a bolt for fixing the two divided outer ring 2 to each other. be. This bolt 5 is mainly designed for convenience during assembly, and the outer ring 2 is attached to the housing. The bolts 5 are not necessarily necessary because the bolts 4 are fixed.
【００１０】 この球面すべり軸受は、上記構成において、外輪の肉厚寸法ｔおよび幅寸法ｗ を必要とする調心角θに対応して設定したものである。すなわち、調心角θは軸 ３とハウジング４との干渉により制限されるものであり、ハウジング４と軸３と の干渉部位４ａが外径方向に離れる程また軸方向中心に近付く程、調心角θは大 きくなる。つまり、調心角θは干渉部位４ａの設定位置により決めることができ 、さらに干渉部位４ａの設定位置は外輪の肉厚寸法ｔおよび幅寸法ｗにより決め ることができる。したがって、外輪２の肉厚寸法ｔを大きくすることで干渉部位 ４ａをより外径方向に位置させ、さらに幅寸法ｗを小さくすることでより軸方向 中心に近付けることができ、これらにより調心角θを容易に増大させることがで きるのである。このようにすることによって、調心角θを約５０゜以上にするこ とが可能となる。0010 In the above configuration, this spherical sliding bearing has a wall thickness t and a width w of the outer ring. This is set in accordance with the required alignment angle θ. In other words, the alignment angle θ is 3 and the housing 4, and the interference between the housing 4 and the shaft 3 is limited. The more the interference part 4a moves away from the outer diameter direction or the closer it gets to the center in the axial direction, the larger the alignment angle θ becomes. I hear it. In other words, the alignment angle θ can be determined by the set position of the interference part 4a. , Furthermore, the setting position of the interference part 4a is determined by the wall thickness t and width w of the outer ring. can be done. Therefore, by increasing the wall thickness t of the outer ring 2, the interference area can be reduced. By positioning 4a further in the outer diameter direction and further reducing the width dimension w, it is possible to can be brought closer to the center, and the alignment angle θ can be easily increased. It is possible. By doing this, the alignment angle θ can be increased to approximately 50° or more. becomes possible.

An example is shown. This steel rod damper connects the building side member 7 and the ground which are arranged at intervals. A steel rod 9 is inserted into the side member 8, and this steel rod 9 is supported by a spherical slide bearing 10 so as to be able to move up and down. This is what I did. The spherical plain bearing 10 is used for the building side member 7 and the ground side member 8 during an earthquake. This serves to center the deflection of the steel rod 9 due to relative movement with the steel rod 9. Earthquake in seismic isolation equipment The expected level of In some cases, a high alignment angle of As mentioned above, the sliding bearing of the present invention has a high Since the centering angle can be easily achieved, it can be applied to such applications.
