Bearing tester: fan side bearing of the machine's name

Bearing vibration of the bearing vibration is sensitive to bearing damage, such as peeling, indentation, rust, crack and wear will be reflected in the bearing vibration measurement, therefore, through the use of special bearing vibration tester ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Nature of the load impact load, appropriate chooses roller bearings, with grinding wheel to repair parts polishing processing, remove highs and leakage of the original metal, the more rough surface, the better; 。 Due to the high drop point lithium grease, so the point is not in the fire of the fat, NSK bearing lubrication, is to choose form NSK bearings, NSK bearing grease lubrication, choose dust cover or seal rubber seals. How electric cars bearing replacement: introduction to add up the rear wheels level, has a screw face downwards, mat board on the shaft, with a hammer percussion rear axle, unload motor cover, replace the bearing. Machining surface roughness or worn to choose lubricating oil of high viscosity, drops of oil varies with oil viscosity and bearing clearance and the oil hole position different significant changes. Note: no more than degrees, the standard of contact Angle for the °, ° and °, the larger the contact Angle axial load capacity is larger, the smaller the contact Angle bearing can bear radial load and one-way axial load. This kind of material of flake or spheroidal graphite after material's surface is covered, can cambium lubrication graphite layer, therefore has the antifriction and wear resistance. Bearings rolling bearing general, closed type bearing cappedbearin - Methyl amino acetonitrile g with one or two seals, one or two dust cover and a sealing ring and a dust cover of the rolling bearing. Such resistance to acid and alkali bearing comprehensive performance will be improved greatly, as the industrial production of robots, but can use a word to describe its requirements: quick, accurate and stable. 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 imperceptible, only a machine high temperature, bouncing, such as sound, will cause people to notice, but by the time people realized that, most of the shaft has been wear and tear, causing the machine downtime. b gt; Fixed - - - - Simply supported way support this structure, suitable for high accuracy requirement, under the operation condition of the radial force is small, because the other side has simply supported, critical speed is higher than the fixed - - Free support. As for how to choose appropriate therapy instrument bearing therapy instrument bearing mostly stainless steel bearings, because the advantage of the stainless steel bearing is much superior than common characteristics of the bearing steel, at least, it has set the antirust function.
