摘要： PROBLEM TO BE SOLVED: To improve fretting damage resistance by providing a specific fine roughness to at least one on a back face of a back plate in a sliding member, which is assembled in a supporting member on the back face side, and on the front face of the supporting part. SOLUTION: In a sliding member,a sliding bearing alloy is stuck on the surface of a back plate, in which fine roughness of 4-15μmRz is provided on the back. If roughness of the back plate back face 20 exceeds 4μmRz , the tip of the back plate projection part 20a is crashed by plastic deformation in the part in which fastening stress is locally increased during assembly to a connecting rod 3, and the back plate and a connecting rod bore face 21 are brought into mutual contact uniformly with each other. Even if fretting is caused under a such condition in which a contact part is uniformly distributed and load distribution is unified, stress on the contact face is distributed between 20, 21 via a contact part 21a, so that damage is hardly caused. On the other hand, the roughness exceeds 15μmRz , noise is likely caused because of increase of a bearing clearance.

摘要： PURPOSE:To obtain a copper-based sliding material having excellent bearing characteristics, particularly having excellent wear resistance and seizing resistance under the condition of boundary lubrication in a material which contains specific amounts of graphite, alumina and the balance copper by dispersing said alumina grains into the copper matrix. CONSTITUTION:The copper-based sliding material consisting of, by weight, 1-10% particularly 1-3% graphite, 1-7% particularly 1.5-3% alumina and the balance copper and in which the alumina grains are dispersed into the copper matrix is provided. In said material, the alumina grains 3 are taken in the copper grains as the matrix which provides strength and heat resistance to the sliding material and the graphite 2 as a solid lubricant exists around the copper grains 1 as shown in the drawing. In the above-mentioned constitution, the alumina grains 3 which improve wear resistance are tightly retained by the copper grains 1 and do not fall off even when exposed to a sliding surface 4. Said sliding material therefore has drastically improved wear resistance and seizing resistance under the condition of boundary lubrication.
