悅翔固定升降機(jī)http://m.kkwl.net/對軸承材料性能的基本要求是與軸頸配合后應(yīng),具有良好的減摩性、耐磨性、磨合性和摩擦相容性,其中磨合性是指軸承材料在短期輕載的磨合過程中形成相互吻合的表面粗糙度、減小摩擦和磨損的性能;摩擦相容性是指防止軸承材料與軸頸材料發(fā)生粘附或防止軸承和軸頸燒傷的性能。具有足夠的強(qiáng)度,包括抗壓、抗沖擊和抗疲勞強(qiáng)度。具有良好的摩擦順應(yīng)性和嵌入性。摩擦順應(yīng)性是指軸承材料靠表面的彈塑性變形來補(bǔ)償滑動(dòng)表面初始配合不良的性能;嵌入性是指軸承材料容許外來硬質(zhì)顆粒嵌人而避免軸頸,表面刮傷或減輕磨粒磨損的性能。一般硬度低、彈性模量低、塑性好的材料具有良好的摩擦順應(yīng)性,其嵌入性也較好。
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.
