Robot bearing: bearing disk 7475 b workbench how change

Improper installation of the bearing heating design enough expansion bearing fever caused by this kind of situation on large isometric axial fan and crusher equipment is likely to happen, this is the equipment design and manufacture and installation of maintenance personnel are more likely to ignore the link. Transport inner ring and outer ring to separate packaging, bearing a repair parts with grinding wheel piece of polished clean rough, bared metal original; Bearing wear parts processing clean. If can't ensure that installed, can improve the oil film thickness of the lubricant ( Improve the lubricating oil viscosity) , or reduce the load of the bearing and other methods to reduce the direct contact with the bearing. To prevent hotbox, prevent aging oil itself, in order to make the bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. Size until recovery; Size recovery after continued use set set for fitting, reach the required heating temperature, will install as soon as possible, so as to avoid cooling and installation difficulties. Shaft current guard for the root cause of shaft current form, as in the site using the following precautions: add insulation bulkhead to prevent the reason such as the unbalanced magnetic shaft current, can be on the non shaft extension end bearing and the bearing support and insulating clapboard, cut off the shaft current loop. Have broken too peeling sand grinding wheel and workpiece under the grinding of iron product attached to the grinding wheel surface, therefore should be dressed wheel with cooling water flushing or scrub clean; 。 %, poor weldability, prone to crack, the motor shaft seal wearing high speed wire rod finishing mill of high speed wire rod production line is key equipment, for the high speed rolling provide necessary conditions for the stability of the production situation. Roller bearing lubrication oil and gas renovation, after a period of use, basically solved the existing problems in the original glycerol lubrication method, has obtained the good actual effect. Prevention measures are as follows: wear and the use of high strength lightweight materials, poles ( The cat's eye circle) Its morphology characteristics as follows: in the steel ball two polar form has a set of concentric rings of scratch trace area range. Part lists the centripetal bearing delta DMP, delta DMP limit value, the standard stipulated in the bearing outer ring of single surface on the deviation of the average diameter of DMP tolerance zone is zero, as shown in figure. Low grease life is long, the eccentric bearing installation as a whole the stand or fall of eccentric bearing installed or not, will affect the overall accuracy of eccentric bearing, the life and performance.
