摘要： In prior art, the wear resistance and frictional properties of a sliding member are improved by adding bismuth, an alkaline earth metal salt or the like, but not lead, to a polytetrafluoroethylene used as a base resin, in view of the undesirable influences of lead on the environment. However, a further improved wear resistance at a high PV value has been desirable. In the present invention, a sliding member having excellent wear resistance and frictional properties even when used at a high PV value can be obtained by using a thermosetting resin as a base resin in a proportion of 50 to 80 vol % and adding thereto a PTFE with a molecular weight of 3,000,000 or more in a proportion of 10 to 40 vol % and bismuth and/or a bismuth alloy in a proportion of 1 to 20 vol %.

摘要： PROBLEM TO BE SOLVED: To provide a bearing device of a compressor for a refrigerator which can widen a clearance between a sliding surface of a bearing and a crankshaft surface in starting, while narrowing the clearance between the sliding surface of the bearing and the crankshaft surface, in regular operation of the compressor for the refrigerator. SOLUTION: A thickness of a resin sliding layer 3 is set so that a bearing clearance C2 in starting becomes relatively large within a range of 2.5-20% to a bearing clearance C1 in the normal service operation. Thus, since reduction in compression efficiency of the compressor for the refrigerator by axial run-out of a crankshaft 4 is prevented in the normal service operation, while narrowing the bearing clearance C1, since the bearing clearance C2 becomes large within a range of 2.5-20% to the normal service operation in starting, direct contact between the sliding surface of the bearing 1 and the crankshaft 4 surface can be prevented.

摘要翻译：解决的问题：提供一种用于冰箱的压缩机的轴承装置，其能够在起动时加宽轴承的滑动面和曲轴表面之间的间隙，同时缩小轴承的滑动表面与轴承的滑动面之间的间隙曲轴表面，在冰箱的压缩机的正常运行中。解决方案：树脂滑动层3的厚度被设定为使得起动时的轴承间隙C2在正常维护操作中与轴承间隙C1的2.5-20％的范围内相对较大。因此，由于在正常维修作业中防止了通过曲轴4的轴向流出而使冷藏库的压缩机的压缩效率降低，同时在使轴承间隙C1变窄的同时，由于轴承间隙C2变大，在启动时的正常维修操作为20％，可以防止轴承1的滑动表面与曲轴4表面之间的直接接触。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To further enhance abrasion resistance and frictional characteristics of a sliding composition and a sliding member under a high PV value condition to fulfill the demand for further enhancement of abrasion resistance under the high PV value condition, though abrasion resistance and frictional characteristics of the sliding member have been heretofore enhanced by incorporating into a polytetrafluoroethylene as a base resin bismuth, an alkaline earth metal salt or the like instead of lead in consideration of the environment. SOLUTION: The sliding member excellent in abrasion resistance and frictional characteristics even when used under the high PV value condition comprises 50-80 vol% of a thermosetting resin as the base resin and, incorporated thereinto, 10-40 vol% of a PTFE having a molecular weight of at least 3,000,000 and 1-20 vol% of bismuth and/or a bismuth alloy.

摘要： PROBLEM TO BE SOLVED: To provide a sliding member for a vehicular shock absorber with improved running stability, by quickly generating a frictional force between the sliding member and a piston rod to be suitable for a state of a road surface, in extension and contraction of the shock absorber, respectively.SOLUTION: A patterned indented area with an index X of cushion characteristics of 2.5×10(μm)≤X≤5.0×10(μm)is formed on a surface of a resin layer 4 of the sliding member 1. When a vehicle runs on a rough road, the frictional force is increased in the sliding member of shock absorber on a contraction side, on the other hand, the frictional force is kept to be low in the sliding member of shock absorber on an extension side. The contraction-side shock absorber suppresses amplitude, on the other hand, the extension-side shock absorber secures grounding of vehicle wheels on the road surface. Therefore, the running stability of vehicle is improved.

摘要： PROBLEM TO BE SOLVED: To provide a sliding resin composition which can reduce oil-repellency of PTFE even in conditions where lubricating oil is scarce, can prevent discharge of the lubricating oil from a sliding surface and, thereby, hardly causes the seizure. SOLUTION: The resin composition 1 in such a state that particles of PTFE 3 allowing an inorganic compound 4 having oil-absorptivity to be embedded on the surface of the particles of PTFE 3 are dispersed is used and, thereby, the inorganic compound 4 having the oil-absorptivity absorbs and retains the lubricating oil and can reduce oil-repellency of PTFE 3 on the sliding surface. Therefore, the inorganic compound 4 can prevent discharge of the lubricating oil from the sliding surface and the resin composition 1 hardly seizes. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a multi-layered resin sliding member that shows an enhanced non-seizure property by increasing a ratio of a resin layer by adding rigid particles to a porous metallic layer to increase abrasion resistance and reducing a ratio of the porous metallic layer at the sliding surface.
SOLUTION: It is possible to partially increase hardness of the multi-layered resin sliding member since the porous metallic layer contains the rigid particles. Therefore in case of making the porous metallic layer and the resin layer co-exist on the sliding surface by cutting the sliding surface of the multi-layered resin sliding member, even if the content of the porous metallic layer of the sliding surface is decreased, abrasion resistance of the porous metallic layer can be enhanced. Since the ratio of the resin of the sliding surface is increased by decreasing the content of the porous metallic layer of the sliding surface, the non-seizure property can be enhanced. In this way it is possible to construct the composite resin sliding member showing excellence in the abrasion resistance and the non-seizure property by the porous metallic layer's containing the rigid particles.

摘要翻译：解决的问题：提供一种多层树脂滑动构件，其通过增加刚性颗粒到多孔金属层以增加树脂层的比例以增加耐磨性并降低比例来显示出增强的非咬合性能的多孔金属层。解决方案：由于多孔金属层包含刚性颗粒，可以部分地增加多层树脂滑动构件的硬度。因此，通过切割多层树脂滑动构件的滑动面，使多孔金属层和树脂层共存在滑动面上的情况下，即使滑动面的多孔金属层的含量降低，可以提高多孔金属层的耐磨性。由于通过降低滑动表面的多孔金属层的含量来增加滑动表面的树脂的比例，因此可以提高非咬合性能。以这种方式，可以通过含有刚性颗粒的多孔金属层来构建显示出优异的耐磨性和非咬合性能的复合树脂滑动构件。版权所有（C）2006，JPO＆NCIPI
