悦翔固定升降机http://www.jnyuexiang.com/对轴承材料性能的基本要求是与轴颈配合后应，具有良好的减摩性、耐磨性、磨合性和摩擦相容性，其中磨合性是指轴承材料在短期轻载的磨合过程中形成相互吻合的表面粗糙度、减小摩擦和磨损的性能；摩擦相容性是指防止轴承材料与轴颈材料发生粘附或防止轴承和轴颈烧伤的性能。具有足够的强度，包括抗压、抗冲击和抗疲劳强度。具有良好的摩擦顺应性和嵌入性。摩擦顺应性是指轴承材料靠表面的弹塑性变形来补偿滑动表面初始配合不良的性能；嵌入性是指轴承材料容许外来硬质颗粒嵌人而避免轴颈，表面刮伤或减轻磨粒磨损的性能。一般硬度低、弹性模量低、塑性好的材料具有良好的摩擦顺应性，其嵌入性也较好。
Yue Xiang basic requirement for fixed lifts bearing material properties after mating with the journal should have good anti-friction, wear resistance, running and friction compatibility, which refers to the break-bearing material in the short run - light load the process of formation of the surface roughness of the mutual agreement, reducing friction and wear performance; compatibility means preventing friction bearing material and journal material adhered or prevent the occurrence of the journal bearing and burn performance. Have sufficient strength, including compressive strength, impact and fatigue strength. Compliance with good friction and embeddedness. Compliance friction bearing material by means of plastic deformation to compensate for surface sliding surfaces with poor initial performance; embedding refers bearing material to allow foreign hard particles embedded avoid journal, surface scratches or mitigate abrasive wear performance. Low general hardness, low elastic modulus, plastic material has good friction good compliance, its embeddedness better.
