The use of the bearing and custody - bearing knowledge

Use attention compared with the general machinery parts, the precision of the rolling bearing is higher, therefore also correspondingly should be careful when using. 1) Keep the bearing and its surrounding clean 2) When used carefully if careless to the bearing to strong impact when using, can cause a scar, indentation, bearing fracture, etc. 3) Use the right tools (4) Note bearing anti-rust avoid use in damp places, and to not make sweat stained, gloves should be worn. 5) The user should be familiar with bearing 6) Set bearing using the code of conduct, bearing a safekeeping, bearing and its surrounding clean c b, the size of the installation site and processing quality of test installed d, e, after inspection, remove the g f, maintenance ( Regular inspection) H, additional bearing lubricant safekeeping bearing were coated with right amount at the time of delivery of anti-rust oil and anti-rust paper, as long as the packaging is not damaged, the quality of the bearing will be guaranteed. But long stored in less than 65%, the temperature is 20 degrees Celsius temperature conditions, the shelf in 30 cm above the ground is advisable. In addition, { TodayHot} Place should avoid direct sunlight or of safekeeping and touch the walls of the cold. The installation of the bearings before installation note 1) Preparation of bearings due to bearing antirust processing and packaging, so do not open the packing before installation. In addition, the coating on bearing anti-rust oil has good lubrication performance, for the general purpose of bearing or bearing grease filling, can not directly use cleaning. But for the instrument bearing or bearing for high-speed rotation, the application of clean cleaning oil washed away anti-rust oil, when the bearing is easy to rust, not for a long time. 2) Axis and the inspection cleaning bearing shell and shell, confirm no scar or mechanical processing of burr. Shell has absolutely can not have abrasives ( SiC and Al2O3, etc. ) Sand, scraps, etc. Next inspection shaft and shell size, shape and machining quality are consistent with those drawings. Before install bearing, in the inspection of shaft and the shell of the mating surface coating machine oil. Bearing the installation method of bearing installation method for bearing type and matching conditions are different. Due to the more commonly as the axis of rotation, so the inner ring and outer ring can respectively USES the interference fit and clearance fit, the outer ring rotates, the outer ring USES the interference fit. ( 1) Installed pumped into general use press, also can use a bolt and nut, when forced to use hammer into the pack. ( 2) Heat will install bearing in oil heating so that it has expanded again after installed on the shaft of the hot set method can avoid unnecessary force, the bearing in a short time to complete installation work. Heating considerations: (1) Generally don't heated above 100 degrees Celsius. 2) Do not allow the bearing contact with the bottom of the tank. Additional heat induction heating device can be used to heat the bearing installation so that it has expanded again after installed on the shaft. Removal periodic inspection or replacement of the bearing parts, the need to remove the bearing. Usually shaft and bearing box almost all want to continue to use, bearing also tend to continue to use. Therefore, the structure design should consider removing bearings, { HotTag} Not damage the bearings, shaft, bearing housing and other components, as well as prepare appropriate removal tool. Remove the interference fit ring, can only add tension on the ring, not by drawing roller ring. Making full use of the maintenance for the bearing bearing and keep its long-term performance, must earnestly to do regular maintenance ( Regular inspection) 。 Through proper periodic inspection, do early detection of fault, prevent accident arrangement is very important to increase productivity and efficiency. 1, clean the bearing will be removed, with photography method such as first and then record the appearance. In addition, to confirm the amount of residual lubricant and lubricant sampling, and then clean the bearing. A, bearing cleaning divided into rough washing and fine washing, can be put in use at the bottom of the container and on the metal frame. B, rough washing, oil using a brush to remove grease or adhesive. If at this time in oil bearing, pay attention to the rolling surface due to foreign bodies such as damage. C, fine cleaning, slowly rotating bearings in the oil, must be carefully. Commonly used cleaning agent for neutral aqueous diesel or kerosene, according to the need to sometimes use warm lye, etc. No matter use which kinds of detergent, often should filter clean. After cleaning, coating anticorrosive oil or antirust grease on the bearing immediately. 2, examination and judgment to judge remove the bearing can be reused, to inspect the dimension precision, rotating accuracy, internal clearance and mating surface, raceway surface, cage and seal rings etc. About the test results that can be used by bearing the judgement or master of bearing. Judgment standard according to the mechanical properties and important degree and inspection cycle. If you have the following injury, bearing shall not be used again, must be replaced. 1) Bearing parts of rupture and defects. 2) The raceway surface material on the surface of the rolling strip. Bearing fault identification method to remove the check, can identify or predict the bearing has a trouble-free operation, to increase productivity and efficiency is very important. Main recognition method is as follows: 1) Through the voice recognition through the voice recognition need to have a lot of experience. Must go through adequate training to achieve voice can identify the bearing and the bearing. Therefore, should as far as possible from staff to carry out the work. With listening gear or listening bar on the shell can be clearly heard the sound of the bearing. 2) Through the method which can identify working temperature comparison method of identification, is limited to use in place of running condition is not change. Therefore, must carry out continuous recording of temperature. Failure, temperature not only, also can appear irregular change. 3) Through the state of lubricant, and the recognition of lubricant sampling analysis, through its pollution degree is mixed with foreign bodies in the judgement or metal powder, etc. The method for larger cannot close observation of bearing or bearing are particularly effective.
