Miniature linear bearing types and purposes

Linear ball bearings ( 轴承) The structure, 结构) Is within the outer ring is equipped with a device, keep a multiple ball, and infinite loop movement. Fixed retainer within the ends of the spring collar, working in the steel ball bearing, 工作) Straight line rail has a gap in the window. This part is made of steel ball by load rolling contact. Bearing bearing lubrication method, divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. If only consider lubrication and oil lubrication. However, grease lubrication can simplify the structure of bearing the surrounding of the special features, compare the pros and cons of grease lubrication and oil lubrication. With very low friction coefficient of the relative movement, so the linear motion ball bearings, 轴承) For machinery and equipment, automation equipment, energy-saving equipment such as the most appropriate selection of bearings. Linear motion bearings, is being more and more widely applied to electronics, machinery, instrument, machine ( machine) People, tools, machinery, food machinery, packaging ( 包装) Machinery, medical machinery, printing machinery, textile machinery, CNC machine tools, automobile and other general or special machinery industry. Using linear ball bearings ( 轴承) Advantages: 1. Due to the flow contact can make the starting friction resistance ( zǔ李) And dynamic friction resistance for minimal, so can save energy, Explanation: to provide natural energy conversion material) Higher speed, easy to get. Bearing bearing lubrication method, divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. If only consider lubrication and oil lubrication. However, grease lubrication can simplify the structure of bearing the surrounding of the special features, compare the pros and cons of grease lubrication and oil lubrication. 2. The load increases, but the friction coefficient is not sensitive to changes, so under heavy load, small friction coefficient, and the accuracy unchanged for a long time, can be used to mechanical cycle to keep for a long time. 3. Linear motion bearings good interchangeability, installation ( ān zhuāng) Easy to use to save time, and make the mechanical structure is novel, small, lightweight characteristic. 4. Save for oil procedures ( shǒu xù) To simplify the purpose of lubrication and maintenance. 5. On both sides of additional oil seal bearing also apply to dust more easily invaded by a foreign body or places. The classification of linear ball bearings ( 分类) : standard ( 使用) The most extensive series there are three kinds of different size series: LM series: metric size series ( Association of southeast Asian nations) ； The LME series: metric size series ( The United States use) 。 L miniature to adapt to the light, thin, short, needs of The Times series, the ultra small diameter ( 直径) Size, inner diameter: 3, 4, 5 mm. L stainless steel ( Acid-proof stainless steel) Blocks are all stainless steel on both ends of the outer ring, steel ball, retainer plastic manufacturing ( zhì zào) 。 S, SLUU l open to remove a column of steel ball, and corresponding to the outer ring, can obtain high rigidity, and prevent the warping of the shaft guide mechanism, adjustable gap can be obtained at the same time, no loose fit. LMOP LMEOP l clearance gather along the long axis on the outer ring to open a single slit type, to adjust fixed bearing shell to cooperate, no loose state. LMADJ LMEADJ l enclosed type oil seal bearing single side or both ends with a lip with special synthetic rubber ( 橡胶) Seal ( 密封) Circle, more suitable for the dust and foreign bodies into field, and can be a very good keep lubricating oil leakage.
