摘要: A resin composition for use in a sliding member, which has higher seizing resistance while maintaining abrasion resistance. The sliding resin composition includes: a resin binder; a solid lubricant; and a protecting and reinforcing agent that is harder and brittler than the resin binder. As the protecting and reinforcing agent, aggregates of particles harder than the resin binder are used. The amount of the protecting and reinforcing agent contained is 1 vol. % or more but 20 vol. % or less of the entire sliding resin composition. The particles harder than the resin binder have an average particle diameter of 10 nm or more but 100 nm or less that is smaller than that of the solid lubricant.

摘要: A slide bearing for an internal combustion engine includes a metal layer having an inner peripheral surface formed to extend along at least a part of a cylindrical shape, and a resin coating layer formed on the inner peripheral surface of the metal layer. The inner peripheral surface of the metal layer has annular or helical groove sections that extend in a generally circumferential direction of a cylindrical shape such that the inner peripheral surface has protrusion sections, which are arranged adjacent to each other in an axial direction of the cylindrical shape and which extend in the generally circumferential direction. The resin coating layer is formed to match shapes of the groove sections and the protrusion sections. t and Rpk satisfy the following relations: 1.0 μm≦t≦5.0 μm; and 0.06≦Rpk/t≦5.04, where t is an average coating thickness of the resin coating layer at positions different from crests of the protrusion sections; and Rpk is a reduced peak height of the resin coating layer.

摘要: Disclosed herein is a sliding member that has a coating layer serving as a sliding surface thereof so that even when foreign matter enters between the coating layer and a partner member, smoothness between them is maintained to prevent the occurrence of seizing. When the coating layer has an elastic recovery ratio of less than 60%, foreign matter that has entered between the coating layer and the sliding surface of a partner member is efficiently embedded in the coating layer. When the coating layer is formed of a resin composition, the resin composition contains a binder resin, a solid lubricant, and metal particles having a Young's modulus of 10 GPa or more but 100 GPa or less.

摘要: A resin composition used for a sliding member to improve seizing resistance. The sliding resin composition includes: a resin binder; a solid lubricant; and aggregates of particles. A coupling force between the particles in the aggregates is smaller than a threshold stress of the resin binder so that the aggregates exposed at a surface of the resin binder are partially detached with a force smaller than the threshold stress of the resin binder. The aggregates of the particles harder than the resin binder are used as a protecting and reinforcing agent, and the amount of the particles contained in the sliding resin composition is 1 vol. % or more but 20 vol. % or less of the entire sliding resin composition. The particles harder than the resin binder have an average particle diameter of between 10 nm and 100 nm that is smaller than that of the solid lubricant.
