Bearing machine: measure bearing clearance is what mean

Ok, get into the business, below the sauvy technology is how to carry out online repair it? Sauvy engineers to the scene just spent hours was finished on bearing repair work, here we'll look at how they do it. Bearing examination should focus on what & amp; #; Bearing the quality first, check whether there is grease metamorphism, agglomerate, impurities such as adverse situation, this is the important basis of reason judge bearing damage. Normal fatigue wear: due to the long running, metal material itself can produce metal fatigue and elastic deformation to plastic deformation, therefore, shaft and bearing inner ring mating surface generation gap, which lead to the relative rotation of the bearing inner ring and the shaft, cause the shaft wear and tear; 。 According to statistics, in the use of roller bearing of rotating machinery, due to damage of rolling bearing fault accounting for %, as a result, the working condition monitoring and fault diagnosis of rolling bearings technology research more and more get people's attention. Load: different load affects the viscosity of the grease of choose and buy, and performance, for higher temperature, due to the better thermal stability, is considering solid or gas lubricant. Equipment problems, the author analyzes the reasons of axial appear wear has a lot of, but the main reason is the nature of metal used to manufacture shaft, metal high hardness, but concession sex difference ( Cannot recover after a deformation) , low shock resistance, fatigue resistance performance is poor, so easy to cause adhesion wear, abrasive wear, fatigue wear and fretting wear, most of the axial wear problem is imperceptible, only a machine high temperature, bouncing, such as sound, most of the shaft has been badly worn, thus making machine downtime. Remove the bearing inspection: if bearing a serious fault and fever for some reason, the bearing should be removed, identify the cause of fever; If the bearing fever accompanied by noise, may be bearing cover and shaft wipe dry or lubricating grease. So we get a cage, a steel ball thoroughly of the bearing, high temperature tempering instantaneous high temperature can make the surface layer of the grinding area ~ n - constant depth Methyl amino acetonitrile m) Be heated to a temperature higher than the workpiece temperature tempering heat. Con - cone inner circle Methyl amino acetonitrile e tapered roller bearing inner ring, outer spherical sphericaloutsidesurface surface was part of the surface of the ball bearing outer ring. Sauvy carbon technology is a kind of application technology of polymer materials, is the use of the comprehensive performance of materials and corresponding repair process to repair worn parts, restore the original size tolerance and meet the equipment operation condition, equipment in order to achieve the purpose of application for a long time. Heat insulation and cooling, interlocking don't careless, can, for example, for the purity of the work environment, according to the seriousness of the pollution, can L life by a coefficient, the coefficient of from. Bearing installation running record, macro inspection include: changes of the shapes and sizes, Including vibration analysis, dynamic function and roll roundness analysis) 。
