FAG bearings are Shaker more difficult to control the main sources of vibration, due to a vibrating screen is a great incentive for maintenance of bearings the speed limit and the coefficient of friction, so the radial bearing is very big, vibrating screen in the course of work, a large exciting force will cause the elastic vibration of bearing system. If poor lubrication, produces larger friction FAG bearing temperature rise too high, thermal expansion is too large, the radial clearance is significantly reduced, which in turn exacerbates the friction, temperature rise further.
FAG bearings locking approach plain is divided into two types:
1. the report of FAG bearings fixed on screws
Simply screw hole on the inner ring extended local locks, housing export fixed, fixed on screws with hex wrench locking. Please select the appropriate hex wrench.
2. fair locking sleeve FAG bearings
Fair locking sleeve had a recess of FAG bearings of vibration and temperature, inside this recess hole into a fair, in the inner ring of the bearing seat also has a local fair. Sleeve on the inner ring on the fair position, toward the direction of the axis of rotation, rotating Blaster up fair know FAG bearings sleeve Garter, hex wrench lock screw tightly.
FAG bearings with eccentric system vibration system, can be considered a single degree of freedom system. Bearing drive shaft and the driven shaft a resonance frequency of the numerical system exists, if a vibration frequency, resonance frequencies close to, resonance occurs. In addition, due to the bias in the centrifugal inertial force, will therefore have a flexural vibration material factors influencing bearing life, if a speed close to the threshold, bending resonance occurs.
From rust, cracks, spalling, indentation, abrasion, are reflected in the fag bearing vibration measurement, bearing vibration damage to the bearing is very sensitive, so bearing by using a special measuring bearing vibration (frequency Analyzer, etc) you can measure the size of the vibration, through frequency not infer exceptions to the specific situation. Due to the measured value of FAG bearings use conditions or sensor installation locations vary, therefore requires prior analysis and comparison of measurement values for each machine after the judging criteria.
FAG bearings even with minor injuries such as split, also is making an abnormal sound and irregular sound, with acoustic logging can be distinguished using acoustic measurement, operation FAG checking bearing size and sound of the rolling sound, playing the role of prevention in advance.
If you use oil hole can directly measure the fag bearing outer ring temperature is more appropriate. Under normal circumstances, the bearing temperature, generally depending on the bearing outside of room temperature may speculate. If lubricated, install suitable, the bearing temperature is rising dramatically, and abnormal high temperature occurs, in which case you must stop and take the necessary precautions. Typically, the fag bearing temperature as the operation began slowly to rise, 1-2 hours to stabilize. Bearing normal temperature for the thermal capacity of the machine, heat dissipation, speed and load vary. If necessary, using heat sensors can monitor FAG bearing temperature, automatic alarm and temperature exceeding a specified value or stop preventing the burning shaft accident.
