(57) [Summary] [Purpose] To prevent runout during rotation and reciprocating motion of the shaft member due to excessive radial clearance in the bearing. [Structure] A plain bearing 1 is fitted in a concave inner diameter portion 2a of an outer ring 2, and is mounted on a shaft member 3 in a state where a predetermined bearing radial clearance R is provided. The plain bearing 1 is compressed in the axial direction X by one end 2b of the outer ring 2 and a retaining ring 5 attached to the other end 2c. Since the plain bearing 1 has a corrugated shape, when it is compressed in the axial direction X, a dimensional change occurs in the radial direction, and the changed size is proportional to the compression size.
Therefore, the bearing radial clearance R can be freely adjusted by adjusting the axial length X0 of the plain bearing 1.
Description
【０００１】[0001]
本考案は、一般産業機械の回転軸あるいは往復動軸等を支持する滑り軸受であ って、軸受ラジアルすきまを自在に調整可能としたものに関する。 The present invention relates to a plain bearing that supports a rotary shaft or a reciprocating shaft of a general industrial machine, in which a bearing radial clearance can be freely adjusted.
【０００２】[0002]
図４に示すように、高分子材からなる滑り軸受１１は、一般に、筒形状をなし 、外環１２に保持された状態で軸部材１３に軸受ラジアルすきまＲをもって装着 される。 As shown in FIG. 4, the plain bearing 11 made of a polymeric material is generally cylindrical and is mounted on the shaft member 13 with a bearing radial clearance R while being held by the outer ring 12.
【０００３】[0003]
軸受ラジアルすきまは使用条件・目的、用途等に応じて最適値に設定する必要 があるが、従来の滑り軸受では、すきまの値に応じて多種類の軸受を準備するか 、あるいは、軸受の摺動面を再加工してすきま調整を行なう必要があるため、在 庫管理上、コスト管理上好ましいとは言えない。また、長時間運転等により摺動 面に摩耗が生じ、軸受ラジアルすきまが過大になることがある。軸受ラジアルす きまが過大になると、軸部材に回転や往復運動時の振れが発生し易く、軸受及び 周辺機器の耐久性、振動、騒音等の面で好ましくない。 The bearing radial clearance needs to be set to the optimum value according to the operating conditions, purpose, application, etc., but with conventional plain bearings, it is necessary to prepare various types of bearings according to the clearance value, or Since it is necessary to rework the moving surface to adjust the clearance, it cannot be said to be preferable in terms of inventory management and cost management. Further, the sliding surface may be worn due to long-time operation, etc., and the radial clearance of the bearing may become excessive. If the bearing radial clearance is too large, the shaft member is liable to shake during rotation or reciprocation, which is not preferable in terms of durability, vibration, noise of the bearing and peripheral equipment.
【０００４】 そこで、本考案の目的は、軸受ラジアルすきまを自在に調整可能とすることに より、上記問題点の解消を図ることにある。Therefore, an object of the present invention is to solve the above problems by making it possible to freely adjust the bearing radial clearance.
【０００５】[0005]
本考案のすきま調整型滑り軸受は、断面が波形形状の高分子材からなる。 The clearance adjustable slide bearing of the present invention is made of a polymer material having a corrugated cross section.
【０００６】[0006]
本考案の滑り軸受は断面が波形形状をなすため、軸方向に圧縮すると、径方向 に寸法変化をおこす。しかも、変化する寸法が圧縮寸法に比例する。したがって 、この滑り軸受の軸方向長さを調整することによって軸受ラジアルすきまを自在 に調整することができる。 Since the plain bearing of the present invention has a corrugated cross section, when it is compressed in the axial direction, the dimension changes in the radial direction. Moreover, the changing size is proportional to the compression size. Therefore, by adjusting the axial length of this plain bearing, the bearing radial clearance can be adjusted freely.
【０００７】[0007]
以下、本考案の実施例を図面に従って説明する。 Embodiments of the present invention will be described below with reference to the drawings.
【０００８】 図１に示すように、滑り軸受１は外環２の凹状内径部２ａに嵌め合わされ、所 定の軸受ラジアルすきまＲを設けた状態で軸部材３に装着されている。この滑り 軸受１は、摺動用エラストマーあるいはプラスチック等の高分子材を用いて形成 されたもので、その断面は波形形状をなしている。尚、高分子材は、使用条件・ 目的、用途等により最適材質を選定して用いると良い。As shown in FIG. 1, the plain bearing 1 is fitted in the concave inner diameter portion 2 a of the outer ring 2 and is mounted on the shaft member 3 in a state where a predetermined bearing radial clearance R is provided. The slide bearing 1 is made of a polymer material such as a sliding elastomer or plastic, and has a wavy cross section. For the polymer material, it is advisable to select and use the optimum material according to the usage conditions, purpose, application, etc.
【０００９】 滑り軸受１は、外環２の一方の端部２ｂと他方の端部２ｃに装着された止め輪 ５とで軸方向Ｘに圧縮されている。図２に示すように、滑り軸受１は波形形状を なすため、軸方向Ｘに圧縮されると径方向に寸法変化をおこし、しかも、変化す る寸法ΔＲが圧縮寸法ΔＸに比例する。そのため、この滑り軸受１はその軸方向 長さＸ０を調整することにより、軸受ラジアルすきまＲを自在に調整することが できる。本実施例では、滑り軸受１の軸方向長さＸ０を、止め輪５の装着位置Ｘ １および止め輪５の幅寸法Ｘ２によって調整する構成にしてある。したがって、 これらを適宜設定することにより、使用条件・目的等に応じた最適な軸受ラジア ルすきまＲを容易に設定することができる。しかも、長時間運転により滑り軸受 １の摺動面に摩耗が生じ、軸受ラジアルすきまＲが過大になったような場合には 、止め輪５を幅寸法Ｘ２の大きなものに取換えることによって、軸受ラジアルす きまＲを適性値に設定し直すことができる。また、副次的効果として、滑り軸受 １の内径部に複数の凹部１ａが形成され、これがグリース等の潤滑剤を保持する 作用をなすため、摺動面における潤滑剤の渇枯がなく、耐久性の向上が図られる といった利点もある。The plain bearing 1 is compressed in the axial direction X by one end 2b of the outer ring 2 and a retaining ring 5 attached to the other end 2c. As shown in FIG. 2, since the plain bearing 1 has a corrugated shape, when it is compressed in the axial direction X, a dimensional change occurs in the radial direction, and the changing dimension ΔR is proportional to the compression dimension ΔX. Therefore, the bearing radial clearance R can be freely adjusted by adjusting the axial length X0 of the plain bearing 1. In this embodiment, the axial length X0 of the plain bearing 1 is adjusted by the mounting position X1 of the retaining ring 5 and the width dimension X2 of the retaining ring 5. Therefore, by appropriately setting these, it is possible to easily set the optimum bearing radial clearance R according to the usage conditions, purpose and the like. In addition, when the sliding surface of the plain bearing 1 is abraded due to long-term operation and the bearing radial clearance R becomes excessive, the retaining ring 5 may be replaced with a larger one in the width dimension X2. The radial clearance R can be reset to an appropriate value. In addition, as a secondary effect, a plurality of recesses 1a are formed in the inner diameter of the sliding bearing 1, which acts to retain a lubricant such as grease, so that there is no exhaustion of the lubricant on the sliding surface and durability is maintained. There is also an advantage that it can be improved.
【００１０】 図２に示す実施例は、外環２の一方の端部２ｂに内ねじ２ｄを形成し、この内 ねじ２ｄに進退自在に螺着させたナット６により、滑り軸受１の軸方向長さＸ０ を自在に調整し得る構成にしたものである。ナット６を締め込んで滑り軸受１側 に進出させると、滑り軸受１が軸方向Ｘに圧縮され軸受ラジアルすきまＲが小さ くなる。図１に示すものに比べ、軸受ラジアルすきまＲの調整をより一層容易に 行なうことができる。また、類似の構成として、軸部材３の外周面に外ねじを形 成し、この外ねじにナットを進退自在に螺着させる構成が考えられる。In the embodiment shown in FIG. 2, an inner screw 2d is formed on one end 2b of the outer ring 2, and a nut 6 screwed to the inner screw 2d so as to move back and forth is used to axially move the sliding bearing 1. The length X0 can be freely adjusted. When the nut 6 is tightened and advanced to the side of the plain bearing 1, the plain bearing 1 is compressed in the axial direction X, and the bearing radial clearance R becomes small. The radial clearance R of the bearing can be adjusted more easily than that shown in FIG. In addition, as a similar configuration, an external thread may be formed on the outer peripheral surface of the shaft member 3, and a nut may be screwed onto the external thread so as to move back and forth.
【００１１】 尚、以上説明した実施例では、滑り軸受１を外環２の凹状内径部２ａに装着し たものを例示したが、本考案はこれに限定されず、例えば、滑り軸受１をハウジ ング等の凹状内径部に直接装着する構成とすることも可能である。In the embodiment described above, the sliding bearing 1 is mounted on the concave inner diameter portion 2a of the outer ring 2, but the present invention is not limited to this. For example, the sliding bearing 1 may be It is also possible to adopt a configuration in which it is directly attached to a concave inner diameter portion such as a ring.
【００１２】[0012]
本考案は、波形形状の高分子材からなる滑り軸受の軸方向長さを調整すること により、軸受ラジアルすきまを自在に調整可能としたため、使用条件・目的等に 応じて軸受ラジアルすきまを最適値に容易に設定することができる。しかも、長 時間運転等により軸受ラジアルすきまが過大になったような場合には、滑り軸受 の軸方向長さを縮小させることにより、適正な軸受ラジアルすきまに容易に調整 し直すことができる。したがって、本考案によれば、軸受ラジアルすきまの拡大 による軸部材の振れを容易に抑制することができ、軸受及び周辺機器の耐久性を 向上させると同時に、振動、騒音といった弊害を解消することができる。 In the present invention, the bearing radial clearance can be freely adjusted by adjusting the axial length of the corrugated polymer bearing, so the optimum value of the bearing radial clearance can be set according to the operating conditions and purposes. Can be easily set. In addition, if the bearing radial clearance becomes excessive due to long-time operation, etc., it is possible to easily readjust the bearing radial clearance by reducing the axial length of the plain bearing. Therefore, according to the present invention, it is possible to easily suppress the runout of the shaft member due to the expansion of the bearing radial clearance, improve the durability of the bearing and peripheral equipment, and at the same time eliminate the adverse effects such as vibration and noise. it can.
