What is the effect of bearing instrument: auto bearing aging

Filter to filter the signal through a fengfeng values, the output signal is the sawtooth waveform, draw the fault signal spectrum diagram, according to the power spectrum of spectrum filter interception by the frequency shift. Overheating become powerful, in the diffuser, to change the direction of flow and gas pipeline cross-section area increases the air flow deceleration, this deceleration function converts kinetic energy into pressure energy. Bearing heated rapidly remove the suit on journal, if the two bearing rolling bearing in the bearing ( Another bearing fixed on the shaft and bearing seat) Set aside axial clearance between and side cover, can avoid the above phenomenon. M/s, the oil viscosity ℃ - Mm/s, applicable L - lubricating oil 退火, AN oil or total loss system, compressor oil, turbine oil or N Spindle shaft linear velocity. To make progress in the sawtooth signal processing, the peak value of energy can be obtained through frequency amplitude ( GSE value) And peak energy spectrum ( GSE spectrum) By the gses spectrum can indeed to see rolling bearing defect of frequency, large amplitude spectrum corresponding gSE spectrum f is bearing failure parts 暲 frequency, the fault characteristic frequency outside sha-lu BPFI in sha-lu BSF roller cage) , you can tell a part of the bearing failure. Be butter covering many ABS ABS probe sensor fault cases was caused by a bearing too much butter, too much of the butter when installing wheel is easy to be pushed to the probe. Industrial use of ball bearing meet the standard of AISI, ball and ring usually are made from high chromium steel, rockwell hardness ( RockwellC - scalehardn - Methyl amino acetonitrile ess) About the - In between. So must pay attention to in the bearing part purchase acceptance check, first of all should use normal manufacturer of the product, the key parts adopt imported bearing, even such as SKF bearings, NSK bearings, FAG TIMKEN bearings at bearings. Within the family with good motor factory will H stand number in high voltage motor, from using a ball bearing, ball bearing, bearing a column, the running effect is very good. Bearing components deformation; Temperatures can damage or destroy the lubricant; Reason: high electric load; Improper thermal channel; A glut of load or speed cooling or insufficient lubrication; Solution: temperature or load control; The appropriate thermal channel; Supplementary cooling; Outer ring fault symptoms: typically stretch along the circumferential direction is parallel cracks. Bearing with dust cover or seal associated with the use requirements of the bearing, when installation should be the sleeves or rolling bearing pressure in the wheel hub bore, and then loaded on the shaft. — — Bearing can be used for high temperature and low speed, the special heat treatment, sheet metal riveting cage, large clearance, after phosphating, grease, use the temperature can exceed ℃.
