SKF bearing using normative analysis

Rolling bearing installation space can accommodate in SKF bearing installation space type bearing due to the design of shafting pay attention to the rigidity and strength of shaft, so generally, first determine the diameter of axle, bearing inside diameter. But rolling bearing series of a variety of sizes and types, should choose the most suitable type of bearing. Rotation has the required precision machine tool spindle rotating precision of the rolling bearing type, gas turbine and control machine, high rotating accuracy, high speed and low friction, at this time should be used more than 5 level precision bearing. 1, keep the bearing and the surrounding clean. 2, when used carefully: if the careless when used to SKF bearing with intense impact, can cause a scar, indentation, bearing fracture, etc. 3, using appropriate tools. 4, pay attention to the bearing rust. Should avoid to 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: 1) , bearing the custody. 2) , bearing and its surrounding clean 3) , the size of the installation site and processing quality inspection 4) , installation work 5) After install, check 6) And remove the homework 7) And maintenance, Regular inspection) 8) , lubricants added load size, direction and nature of the rolling bearing load bearing load abound change, such as the size of the load, is only the radial load and axial load is a one-way or two-way, the degree of vibration or shock, and so on. After considering these factors, and then to select the most appropriate type of SKF bearing. Inner ring and outer ring of the tilted relative analysis causes the bearing inner ring and outer ring tilted relative factors, and choose the types of bearing can adapt to the conditions of use. If the inner ring and outer ring is too big, the relative tilt SKF bearing damage will cause internal load. So should choose the types of bearing can withstand the tilt. Speed can be adapted to mechanical speed bearing type bearing limit speed not only depends on bearing type is limited to the bearing size, cage type, precision grade, load condition and lubrication method, etc. , therefore, when the choice must consider these factors. Most of rolling bearing used in high-speed rotation of the following: deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings.
