Linear bearing using method, classification and oil lubrication ways

Linear bearing is a widely used precision components in life, for unlimited travel and cylindrical shaft, and used in the industries of food packaging machinery, printing machinery and textile machinery industries, etc. In order to help them master more knowledge of linear bearing, so today the author is for us the linear bearing using method, classification and oil lubrication ways. Linear bearing use method 1, keep the linear motion bearings and its surrounding clean. 2, use the right tools. 3, when used carefully: if the careless when used for linear motion bearings with intense impact, can cause a scar linear motion bearings, indentation, fracture, etc. 4, pay attention to rust of linear motion bearings. Should avoid to use in damp places, and to not make sweat stained, gloves should be worn. 5, the user should be familiar with linear motion bearings. 6, making linear linear motion bearings using the code of conduct: a, linear motion bearings safekeeping, linear motion bearings and its surrounding clean c b, the size of the installation site and processing quality inspection installed d, e, after inspection, remove the g f, maintenance ( Regular inspection) H, the classification of additional linear bearing lubricant ( 1) Standard, gather linear bearing clearance, open rack linear bearings, linear bearings, linear bearings (commonality lengthened 2) Flange linear bearing can be divided into: round flange type, method, elliptical flange, guided round flange, guiding method, guide the elliptical flange type, extended round flange type. According to the specification standard points: is divided into two series of LM and LME series. The code LM series used in Asia, southeast Asia, Japan, South Korea, China, etc. On the basis of metric size, with straight axis diameter tolerance is usually h7. LME series used in Europe, the United States, Germany, Italy and other regions. On the basis of inch size. Also have metric size, with the straight axis diameter tolerance is usually g6. Two big series structure characteristics, in addition to different sizes, different pore size tolerance, its structure is roughly the same. According to the shape points: 1: straight type ( Shapes such as cylinders, generally with the circlip installation, for special occasions requiring small installation size) Flange type (2: The end or middle flange, with installation can use screw to install, flange general points of circular, square and trimming type three) 3: open mouth, Shapes such as straight, appearance has axial slitting, great for special occasions need clearance adjustment, opening and small opening two) According to the performance points: 1: normal ( General performance requirements) Type 2: super ( Long life and large load performance requirements) Linear bearing lubrication ways 1, circulating oil lubrication oil pump will filter the oil transfer to the linear bearing parts, through the linear bearing lubricating oil filter cooling after use. Due to the circulating oil can take a certain quantity of heat, cooling the bearing, therefore method is suitable for high speed bearing parts. 2, spray lubrication with dry compressed air sprayer and lubricating oil mixed form oil mist, spray in the linear bearing, can effectively make the bearing cooling airflow and can prevent the intrusion. This method is suitable for high speed, high temperature lubrication bearing parts. 3, spray lubrication oil pump to pass through the nozzle jet high pressure oil to the linear bearing, into linear bearing the bearing at the other end into the oil in the tank. In linear bearing high speed rotates, rolling element and cage with high rotate speed makes the surrounding air, the air with general lubrication methods are difficult to be sent to the linear bearing lubricating oil, use the method of high-pressure jet spray the lubricating oil must be taken to the bearing, the position of the nozzle should be placed between inner ring and retainer center 4, drip lubrication oil drip lubrication is suitable for need to ration oil linear bearing parts, general every 3 drops of oil A drop of it is advisable to 8 seconds, too much oil will cause the bearing temperature increased. 5, oil bath lubrication oil bath lubrication is the most common lubrication method, suitable for low, medium speed, bearing lubrication. Immersion in the slot, part of the linear bearing lubricating oil by the bearing parts of rotation, and then flow back to the oil level of oil tank should be slightly lower than the lowest at the center of the roller. Above is the linear bearing using method, classification and all knowledge, and several methods of oil lubrication linear bearing is widely used in electronic equipment industry, can be used for food machinery, packaging machinery, medical machinery, machine tools, CNC machine tools, automotive and digital 3 d coordinate measuring equipment such as precision equipment or special machinery industry.
