koyo轴承质料的冶金质量曾经是影响转动轴承早期失效的主要因素。跟着冶金技能(譬喻轴承钢的真空脱气等)进步,原质料质量获得改进。原质料质量因素在轴承失效说明中所占的比重已经明明下降,但它仍然是轴承失效的主要影响因素之一。选材是否恰当仍然是koyo轴承失效说明必需思量的因素。
Metallurgical quality Koyo bearings material used to be the main factors affecting the early failure of rotating bearings. Metallurgical skills (parables of bearing steel by vacuum degassing) progress, quality of raw material improvement. Raw material quality of the relative contribution of factors bearing failure that has obviously declined, but it still is one of the main affecting factors of bearing failure. Appropriateness of the selection remains a factor of Koyo bearings failure description required thought.
koyo轴承金属腐蚀和生锈是汗水的手的要点,占绝大多数的金属腐蚀,在许多情况下无法避免的。手汗会造成腐蚀koyo轴承,主要是汗水在其膜汗水接触面,电化学反应和互动会导致腐蚀,但可避免的,如手套,带来如拿起零件的专业工具。
Koyo bearings points on metal corrosion and rusting is sweat, hand, account for the vast majority of metal corrosion, in many cases could not be avoided. Sweat may cause corrosion Koyo bearings, mainly contacts on the sweat of sweat in his film, electro-chemical reactions and interactions can cause corrosion, but can be avoided, such as gloves, bring as part of professional tools.
润滑脂的作品是从球分离与内外滚道油层使用,油的粘度使用,贴在球和滚道面,由内,外滚道和金属界面球分离,减少了金属表面的磨损和防止空气和水分腐蚀金属,降低振动和噪音,使koyo轴承旋转顺利。
Work is isolated from ball of grease and Raceway formation using both inside and outside, the viscosity of the oil used, posted in ball and roller surface, from the inside, separation of foreign road roller and ball metal interface, reducing wear and prevent air and moisture corrosion of metal surfaces metal, reducing vibration and noise, so that Koyo bearings rotate smoothly.
koyo轴承表现出晚期故障特征到出现严重故障(一般为轴承损坏如抱轴、烧伤、沙架散裂、滚道、珠粒磨损等)时间大都不超过一周,设备容量越大,转速越快,其间隔时间越短。因此,在实际滚动轴承故障诊断中,一旦发现晚期故障特征,应果断判断koyo轴承存在故障,尽快安排检修。
Koyo bearings demonstrate advanced features to a serious failure (often a damaged bearing like arms burn, sand, spallation, Raceway, wear beads and other) most of the time not more than a week, equipment capacity larger, faster the speed, shorter intervals. Therefore, actual in fault diagnosis of rolling bearing once advanced features should be decisive judgment fault of Koyo bearings, arrange for repair as soon as possible.
