- PVD physical vapor deposition
- the bearing surface of the other member has a lubrication liner formed of resin.
- the lubricating liner is made of a fabric made of polytetrafluoroethylene (PTFE) and polyaramid fibers and saturated with a phenolic resin composition.
- PTFE polytetrafluoroethylene

- the metal surface has a surface roughness Ra (centerline average roughness) of 4.0 ⁇ m or more and Rmax (maximum height) of 30.0 ⁇ m or more.
- the fibrous lubricating liner of Patent Document 1 cannot be adjusted by grinding or cutting because the fiber is cut and does not function as a liner when post-processing is performed.

As a result, a liner having a uniform thickness can be formed on the spherical plain bearing.
- the polymerization reaction may be stopped early by adjusting the ultraviolet irradiation time to be short. After the swaging process, the semi-cured liner is sandwiched between the inner ring and the outer ring, and thus cannot be irradiated with ultraviolet rays.
- thermosetting agent to the resin composition.
- ultraviolet irradiation may be performed without heating.
- a thermoplastic resin or a thermosetting resin since the resin does not follow the deformation of the outer ring unless it is in an uncured state, it becomes difficult to perform swaging.

- the main body of the reamer bolt 70 is made of, for example, SUS630.
- the thickness of the liner 74a can be about 0.25 to 0.5 mm.
- the reamer bolt 70 is used for important connecting parts that transmit high torque such as a propeller shaft of a ship, movable wings of an aircraft, and a connecting rod of an automobile engine.
- the reamer bolt 70 used for such an important connecting portion needs to be fitted with a high precision so that the fitting with the bolt hole is free from backlash. Therefore, although the shaft portion 74 of the reamer bolt 70 is finished with high accuracy, it is still advantageous that the dimensions can be adjusted on the bolt side during assembly. Since the reamer bolt according to the present invention has the machine liner 74a, the outer diameter of the body portion can be easily adjusted on the user side even after the resin is cured.
- shank 74 has the self-lubricating machinable liner 74a even if the bolt is inserted or removed at the time of assembly or disassembly, no galling or the like occurs and a long-life reamer bolt 70 is obtained.

- the resin composition of the present invention can be used as a self-lubricating liner by being applied to the sliding surface of a sliding member and cured by ultraviolet irradiation.
- a high temperature / high pressure process is not required for curing the resin composition, and furthermore, the adhesion of the cured resin composition to the coated surface (base surface) is extremely strong, so that the coated surface is roughened. Processing is not necessary. Therefore, a relatively large amount of PTFE can be contained while ensuring the safety of work, and the equipment cost can be reduced.
- the self-lubricating liner thus formed can be formed on various sliding members including a sliding bearing such as a sleeve bearing and a spherical sliding bearing.
- the sliding member is provided with the self-lubricating liner formed from the resin composition of the present invention, the liner surface can be cut or ground, and the inner diameter of the bearing can be adjusted when the shaft is assembled on the end user side.

SUS630ステンレス鋼をH1150条件で熱処理した材料を用いて図1に示すような円筒状のスリーブ軸受(幅(軸方向長さ)12.7mm、外径30.2mm、内径24.9mm)を作製した。このスリーブ軸受の内周面に実施例1~15及び比較例1~8で調製した樹脂組成物を、それぞれ、ディスペンサーを用いて均一に塗布した。次いで、塗布した樹脂組成物に紫外線ランプを用いて紫外線(λ=365nm)を1分間照射して、樹脂組成物を硬化させ、内周面にマシナブルライナーを形成した。次いで、このマシナブルライナーをライナーの厚さが0.25mmになるように切削及び研削し、内径25.4mmに仕上げた。こうして実施例1~16及び比較例1~8で調製した樹脂組成物よりなる23種類のマシナブルライナーについて、以下のような試験により性能評価を行った。
1.ラジアル静的限界荷重(静荷重試験)
この試験におけるAS81934規格要求を下表に示す。AS81934規格では表2の左欄に示すように、スリーブ軸受の材料(アルミ合金とステンレス鋼)及び内径寸法ごとにラジアル静的限界荷重を定めている。実施例1~16及び比較例1~8で用いたスリーブ軸受の材料及び寸法からすれば、表2に記載の型式番号M81934/1-16C016に相当するので、最大試験荷重は140kN(31,400lb)とした。
揺動試験は、常温と温度163℃(+6℃/-0℃)の高温に対して行われる。この試験におけるAS81934規格要求は、常温揺動試験における許容可能なライナー摩耗量の上限値が、1,000サイクル後0.089mm(0.0035in)、5,000サイクル後0.102mm(0.0040in)、25,000サイクル後0.114mm(0.0045in)である。また、高温揺動試験における25,000サイクル後の摩耗量の上限値は0.152mm(0.0060in)である。
この試験におけるAS81934規格要求は、耐油性確認試験後の許容可能なライナー磨耗量上限値が0.152mm(0.0060in)である。上記のようにして作製したマシナブルライナーを有するスリーブ軸受B4を温度71℃±3℃で、下記に示す6種類の油剤a~fにそれぞれ24時間浸漬させた後、油剤から取り出して30分以内に上記の常温揺動試験を行った。ただし、油剤bについては温度43℃±3℃で、24時間浸漬させた。また、油剤eについては上記の揺動試験の75%の面圧条件とした。
油剤b.MIL-DTL-5624タービン燃料油JP4またはJP5
油剤c.MIL-PRF-7808潤滑油
油材d.MIL-PRF-5606油圧作動油
油剤e.AS8243凍結防止剤
油剤f.MIL-PRF-83282作動液
自己潤滑性ライナーのスリーブ軸受の内周面に対する耐剥離性(付着性)について評価するために以下のように試料を作製した。前述の試験で用いたスリーブ軸受(幅12.7mm、外径30.2mm、内径24.9mm)に樹脂組成物を塗布する前に、スリーブ軸受の内周面を、表4に示すような4種類の面粗度になるようにサンドブラスト処理により粗面化した。次いで実施例1で調製した樹脂組成物を塗布し、紫外線を照射してマシナブルライナーを形成した。このマシナブルライナーの厚さが0.25mmとなるまで切削及び研削して、スリーブ軸受の内径を25.4mmに仕上げた。こうして作製した4種類の面粗度の内周面にマシナブルライナーを備えたスリーブ軸受について以下のようなA~Dの条件で試験を行い、剥離の有無を確認した。
B : 液体窒素(-196℃)中に15分間保持後、樹脂の剥離確認:液体窒素から取り出したときの剥離の有無を観察した。
C : 前述のAS81934規格に従って常温にて面圧275MPaで摺動させ、25,000サイクルまでの剥離有無を観測した。
D : 前述のAS81934規格に従って163℃にて面圧275MPa で摺動させ、25,000サイクルまでの剥離有無を観測した。
樹脂組成物中に固体潤滑剤としてのPTFE粉末を加えた場合に、PTFE粉末の粒子径のライナー摩耗への影響を調査するために、実施例1の樹脂組成物において異なる粒子径のPTFE粉末を用いて樹脂組成物を調製し、それらの樹脂組成物から形成したマシナブルライナーについて前述の常温揺動試験を面圧275MPaで10万サイクルまで行い、摩耗量を測定した。得られた結果を表6に示す。また、この結果を用いた粒子径に対する摩耗量を示すグラフを図3に示す。
球面滑り軸受20は、図4に示すように、凹球面状の内周面22aを有する外輪22と凸球面状の外周面26aを有する内輪26と、内周面22aと外周面26aとの間に形成されたマシナブルライナー24を有する。ライナー厚さは、例えば、0.25mm程度とすることができる。
上記球面滑り軸受20をロッドエンドボディ50に組み込んだロッドエンド球面滑り軸受60の例を図6に示す。ロッドエンドボディ50は、球面滑り軸受20を組み込む貫通穴52aを有する頭部52と、メネジまたはオネジ56を設けた軸部54からなる。軸部54は頭部52から貫通穴52aの半径方向に延在する略円筒体である。球面滑り軸受20は貫通穴52aに挿入された後、貫通穴52aの縁に形成されているV溝(不図示)をカシメることによってロッドエンドボディ50に固定される。
図7に示すようなリーマボルト70は、頭部72と、大径の軸部74と、小径のオネジ部76からなる本体部と、軸部74の外周に設けられたマシナブルライナー74aとを備える。マシナブルライナー74aは、上記のいずれかの実施例の樹脂組成物を実施例に記載したような方法で均一に塗布し、硬化させることで形成される。リーマボルト70の本体部は、例えば、SUS630から形成されている。ライナー74a厚さは0.25~0.5mm程度とすることができる。
