    • PROBLEM TO BE SOLVED: To provide a high-precision slide bearing which can obtain precise and stable rotational torque by having a synthetic resin bearing layer on a base material of a sintered metal and usable as the slide bearing for receiving a relatively large radial load or axial load like the load received by, for example, a rotating shaft of a room air conditioner compressor or a car air conditioner compressor and a transmission of an automobile or a construction machine.SOLUTION: A resin layer 2 is integrally provided on the inner diameter surface side of the base material 1 made of the sintered metal of the cylindrical slide bearing. The resin layer 2 includes a resin composition with a fibrous filler mixed into an aromatic polyether ketone based resin. The fibrous filler 3 is distributed in the resin layer while being aligned so that the longitudinal direction of the fibers intersects the rotational direction of the bearing at an angle of 45-90 degrees. The resin layer 2 has a thickness of 0.1-0.7 mm. This structure alleviates the wear and damage of counterpart members which may be caused by the edges of the fibers, so that frictional coefficient is stabilized. The composite slide bearing, which has the synthetic resin bearing layer 2 with the base material 1 of the sintered metal, can thus provide a precise and stable rotational torque.
    • 要解决的问题:提供一种高精度滑动轴承,其可以通过在烧结金属的基材上具有合成树脂轴承层而获得精确和稳定的转矩,并且可用作用于接收相对较大的滑动轴承 径向载荷或轴向载荷,例如由室内空调压缩机或汽车空调压缩机的旋转轴以及汽车或建筑机械的变速器接收的负载。 解决方案:树脂层2一体地设置在由圆柱形滑动轴承的烧结金属制成的基材1的内径表面侧上。 树脂层2包括混合到芳族聚醚酮基树脂中的具有纤维状填料的树脂组合物。 纤维填料3分布在树脂层中,同时对准,使得纤维的纵向方向以45-90度的角度与轴承的旋转方向相交。 树脂层2的厚度为0.1-0.7mm。 这种结构减轻了由纤维边缘引起的对方构件的磨损和损伤,从而使摩擦系数稳定。 具有合成树脂轴承层2与烧结金属的基材1的复合滑动轴承能够提供精确且稳定的转矩。 版权所有(C)2012,JPO&INPIT
