介绍: 精微轴承的套圈及钢球采用精炼轴承钢GCR15(等同于日本的JIS G4805 SUJ2,美国的AISI52100),精炼不锈钢9Cr18(AISI440) 保持架一般采用黄铜皮H62或SPCC钢带冲压制成,也可用不锈钢带3Cr13、1Cr18Ni9或酚醛胶布、塑料、铜料制造。 防尘盖有08AI、SPCC钢带或不锈钢带,1Cr18Ni9制成。 密封圈由橡胶及特弗龙材料制成。 | |||||||||||||||
1.冠形保持架:在装配时把钢球装入特殊的装球口即可,在低速的情况下有较低的启动力矩,转动灵活。 2.浪形保持架:由有爪和无爪组合而成,大多采用不锈钢304或316的材料,适合于中等转速的场合。 3.酚醛保持架:适合于极高的转速,有自润滑的功能,普遍用于牙钻轴承。 Usually,the rings and balls are made of Gcr15 high carton chromium beearing steel (equivalent of JIS G 4805 SUJ2 steel or AISI52100 steel) and 9Cr18 stainless steel(equivalent of AISI440) The shields are made of SPCC or 1Cr18Ni9.The seals are made of synthetic rubber and Teflon The retainers are made of brass strips H62,SPCC steel,3Cr13,1Cr18Ni9,as well as phenolic resin and plastic.1.CROWN RETAINER: The standard metal crown retainer is very light weight, with specially coined ball pockets to reduce torque and provide smooth running characteristics. Material used is 400 series stainless steel. 1.CROWN RETAINER: The standard metal crown retainer is very light weight, with specially coined ball pockets to reduce torque and provide smooth running characteristics. Material used is 400 series stainless steel. 2.RIBBON RETAINER: The closed pocket design of the ribbon retainer is the most common type. The material used is 300 series stainless steel. For low torque applications, a loose clinched ribbon retainer may be available. 3.PHENOLICRETAINER: Plastic crown retainers have the highest speed ratings of any standard retainer type, but have limited availability. |
